Section B: Optirnize Site Utilization (LID Principles)
Review of the information collected in Section 'A' will aid in identifying the principal constraints on site
design and selection of LID BMPs as well as opportunities to reduce imperviousness and incorporate LID
Principles into the site and landscape design. For example, constraints might include impermeable
soils, high groundwater, groundwater pollution or contaminated soils, steep slopes, geotechnical
instability, high-intensity land use, heavy pedestrian or vehicular traffic, utility locations or safety
concerns. Opportunities might include existing natural areas, low areas, oddly configured or otherwise
unbuildable parcels, easements and landscape amenities including open space and buffers (which can
double as locations for LID Bioretention BMPs), and differences in elevation (which can provide
hydraulic head). Prepare a brief narrative for each of the site optimization strategies described below.
This narrative will help you as you proceed with your Low Impact Development (LID) design and explain
your design decisions to others.
The 2010 SMR MS4 Permit further requires that LID Retention BMPs (Infiltration Only or Harvest and
Use) be used unless it can be shown that those BMPs are infeasible. Therefore, it is important that your
narrative identify and justify if there are any constraints that would prevent the use of those categories
of LID BMPs. Similarly,you should also note opportunities that exist which will be utilized during project
design. Upon completion of identifying Constraints and Opportunities, include these on your WQMP
Site plan in Appendix 1.
Site Optimization
The following questions are based upon Section 3.2 of the WQMP Guidance Document. Review of the
WQMP Guidance Document will help you determine how best to optimize your site and subsequently
identify opportunities and/or constraints,and document comp�iance.
Did you identify and preserve existing drainage patterns? If so, how? If not,why?
Yes,proposed grading preserves existing drainage patterns
Did you identify and protect existing vegetation?If so, how? If not,why?
Yes, vegetation outside of grading limits preserved
Did you identify and preserve natural infiltration capacity? If so, how? If not,why?
Yes, area of property outside of grading limits has natural infiltration
Did you identify and minimize impervious area? If so, how? If not,why?
Yes, only impervious areas are building and required parking
Did you identify and disperse runoff to adjacent pervious areas? If so, how? If not,why?
Yes, runoff directed to pervious areas when possible

Section D: Implement LID BMPs
D.1 Infiltration Applicability
An assessment of the feasibility of utilizing Infiltration BMPs is required for all projects, except in the
following case:
❑ Harvest and Use BMPs will be implemented to address the Design Capture Volume (see the
Harvest and Use Assessment below) for all Drainage Management Areas AND the project is
exempt from HMP Performance Standards(Proceed to Section D.2 and Section E).
If the above box remains unchecked, perform a site-specific evaluation of the feasibility of Infiltration
BMPs using each of the applicable criteria identified in Chapter 3.4.1 of the WQMP Guidance Document
and complete the remainder of Section D.1.
Is there an infiltration concern (see discussion in Chapter 2.3.4 of the WQMP Guidance Document for
further details)? ❑ Y �N
If yes has been checked, both Infiltration BMPs and Hydrologic Control BMPs that include an infiltration
functionalities may not be feasible for the site. It is recommended that you contact your Copermittee to
verify whether or not infiltration within the Project is infeasible.
Geotechnical Report
A Geotechnical Report or Phase I Environmental Site Assessment may be required by the Copermittee to
confirm present and past site characteristics that may affect the use of Infiltration BMPs. In addition,the
Copermittee, at their discretion, may not require a geotechnical report for small projects as described in
Chapter 2 of the WQMP Guidance Document. If a geotechnical report has been prepared, include it in
Appendix 3. In addition, if a Phase I Environmental Site Assessment has been prepared, include it in
Appendix 4.
Is this project classified as a small project consistent with the requirements of Chapter 2 of the WQMP
Guidance Document?Q Y � N
Infiltration Feasibility
Table D.1 below is meant to provide a simple means of assessing which DMAs on your site support
Infiltration BMPs and is discussed in the WQMP Guidance Document in Chapter 2.3.4. Check the
appropriate box for each question and then list affected DMAs as applicable. If additional space is
needed, add a row below the corresponding answer.

...have any contaminated groundwater plume in the vicinity of the site? X
If Yes,list affected DMAs:
...geotechnical report identifies other site-specific factors that would preclude effective and safe infiltration? X
Describe here:
If you answered "Yes" to any of the questions above for any DMA, Infiltration BMPs should not be used
for those DMAs and you should proceed to the assessment for Harvest and Use below.

Water Quality Management Plan(WQMP)
Temecula MOB 2
D.2 Harvest and Use Assessment
Please check what applies:
❑ Reclaimed water will be used for the non-potable water demands for the Project.
❑Downstream water rights may be impacted by Harvest and Use as approved by the Regional
Board (verify with the Copermittee).
XThe Design Capture Volume (DCV) will be addressed using infiltration Only BMPs. In such a
case, Harvest and Use BMPs are still encouraged, but it would not be required if the DCV will be
infiltrated or evapotranspired.
If any of the above boxes have been checked, Harvest and Use BMPs need not be assessed for the site. If
neither of the above criteria applies, follow the steps below to assess the feasibility of irrigation use,
toilet use and other non-potable uses (e.g., industrial use).
Irrigation Use Feasibility
Complete the following steps to determine the feasibility of harvesting stormwater runoff for Irrigation
Use BMPs on your site:
Step 1: Identify the total area of irrigated landscape on the site, and the type of landscaping used.
Total Area of Irrigated Landscape: 0.16 acres
Type of Landscaping(Conservation Design orActive Turf): Conservation Design
Step 2: Identify the planned total of all impervious areas on the proposed project from which runoff
might be feasibly captured and stored for irrigation use. Depending on the configuration of
buildings and other impervious areas on the site, you may consider the site as a whole, or
parts of the site, to evaluate reasonable scenarios for capturing and storing runoff and
directing the stored runoff to the potential use(s) identified in Step 1 above.
Total Area of Impervious Surfaces: 1.46 acres
Step 3: Cross reference the Design Storm depth for the project site (see Exhibit A of the WQMP
Guidance Document) with the left column of Table 2-4 in Chapter 2 to determine the
minimum area of Effective Irrigated Area per Tributary Impervious Area (EIATIA).
Enter your EIATIA factor: 3.62
Step 4: Multiply the unit value obtained from Step 3 by the total of impervious areas from Step 2 to
develop the minimum irrigated area that would be required.
Minimum required irrigated area: 5.29 acres
Step 5: Determine if harvesting stormwater runoff for irrigation use is feasible for the project by c
omparing the total area of irrigated landscape(Step 1)to the minimum required irrigated area
(Step 4).
Minimum required irrigated area (Step 4) Available Irrigated Landscape(Step 1)
5.29 acres 0.16 acres

Toilet Use Feasibility
Complete the following steps to determine the feasibility of harvesting stormwater runoff for toilet
flushing uses on your site:
Step 1: Identify the projected total number of daily toilet users during the wet season, and account
for any periodic shut downs or other lapses in occupancy:
Projected Number of Daily Toilet Users:90
Project Type:Commercial
Step 2: Identify the planned total of all impervious areas on the proposed Project from which runoff
might be feasibly captured and stored for toilet use. Depending on the configuration of
buildings and other impervious areas on the site,you may consider the Project site as a whole,
or parts of the site, to evaluate reasonable scenarios for capturing and storing runoff and
directing the stored runoff to the potential use(s) identified in Step 1 above.
Total Area of lmpervious Surfaces:1.46 acres
Step 3: Enter the Design Storm depth for the project site (see Exhibit A) into the left column of Table
2-3 in Chapter 2 to determine the minimum number or toilet users per tributary impervious
acre (TUTIA).
Enter your TUTIA factor:193
Step 4: Multiply the unit value obtained from Step 3 by the total of impervious areas from Step 2 to
develop the minimum number of toilet users that would be required.

lithology of onsite soils should be reported in Appendix 7.
❑ Step 1.6—Are onsite streams capable of delivering Bed Sediment Supply from the site, if any,to
the receiving channel?
Rate the potential: ❑High
❑ Medium
� Low
Results from the analyses of the sediment delivery potential to the receiving channel shou�d be
documented in Appendix 7 and identify, at a minimum, the Sediment Source, the distance to the
receiving channel, the onsite channel density, the project watershed area, the slope, length, land use,
and rainfall intensity.
❑ Step 1.C—Will the receiving channel adversely respond to a change in Bed Sediment Load?
Rate the need for bed sediment supply:
� High
� ❑ Medium
� Low
Results from the in-stream analysis to be performed both onsite should be documented in Appendix 7.
The analysis should, at a minimum, quantify the bank stability and the degree of incision, provide a
gradation of the Bed Sediment within the receiving channel, and identify if the channel is sediment
supply-limited.
❑ Step 1.D-Summary of Step 1
Summarize in Table E.3 the findings of Step 1 and associate a score (in parenthesis) to each step. The
sum of the three individual scores determines if a stream is a significant contributor to the receiving
stream.
� Sum is equal to or greater than eight - Site is a significant source of sediment bed
material —all on-site streams must be preserved or by-passed within the site plan. The
applicant shall proceed to Step 2 for all onsite streams.
• Sum is greater than five but lower than eight. Site is a source of sediment bed material—
some of the on-site streams must be preserved (with identified streams noted). The
applicant shall proceed to Step 2 for the identified streams only.
• Sum is equal to or lower than five. Site is not a significant source of sediment bed
material.The applicant may advance to Section F.

Section G: Source Control BMPs
Source Control BMPs include permanent, structural features that may be required in your Project plans
— such as roofs over and berms around trash and recycling areas — and Operational BMPs, such as
regular sweeping and "housekeeping", that must be implemented by the site's occupant or user. The
Maximum Extent Practicable (MEP) standard typically requires both types of BMPs. In general,
Operational BMPs cannot be substituted for a feasible and effective structural BMP. Using the Pollutant
Sources/Source Control Checklist in Appendix 8, review the following procedure to specify Source
Control BMPs for your site:
1. Identify Pollutant Sources: Review Column 1 in the Pollutant Sources/Source Control Checklist.
Check off the potential sources of Pollutants that apply to your site.
2. Note Locations on Project-Specific WQMP Exhibit: Note the corresponding requirements listed in
Column 2 of the Pollutant Sources/Source Control Checklist. Show the location of each Pollutant
source and each permanent Source Control BMP in your Project-Specific WQMP Exhibit located in
Appendix 1.
3. Prepare a Table and Narrative: Check off the corresponding requirements listed in Column 3 in the
Pollutant Sources/Source Control Checklist. In the left column of Table G.1 below, list each potential
source of Pollutants on your site (from those that you checked in the Pollutant Sources/Source
Control Checklist). In the middle column, list the corresponding permanent, Structural Source
( Control BMPs (from Columns 2 and 3 of the Pollutant Sources/Source Control Checklist) used to

Section I: Operation, Maintenance and Funding
The Copermittee with jurisdiction over the Project site will periodically verify that BMPs on your Project
are maintained and continue to operate as designed.To make this possible,the Copermittee will require
that you include in Appendix 9 of this Project-Specific WQMP:
1. A means to finance and implement maintenance of BMPs in perpetuity, including replacement
cost.
2. Acceptance of responsibility for maintenance from the time the BMPs are constructed until
responsibility for operation and maintenance is legally transferred. A warranty covering a
period following construction may also be required.
3. An outline of general maintenance requirements for the Stormwater BMPs you have selected.
4. Figures delineating and designating pervious and impervious areas, location, and type of
Stormwater BMP, and tables of pervious and impervious areas served by each facility. Geo-
locating the BMPs using a coordinate system of latitude and longitude is recommended to
help facilitate a future statewide database system.
5. A separate list and location of self-retaining areas or areas addressed by LID Principles that do
not require specialized Operations and Maintenance or inspections but will require typical
landscape maintenance as noted in Chapter 5, in the WQMP Guidance. Include a brief
description of typical landscape maintenance for these areas.
The Copermittee with jurisdiction over the Project site wifl also require that you prepare and submit a
detailed BMP Operation and Maintenance Plan that sets forth a maintenance schedule for each of the
BMPs built on your site. An agreement assigning responsibility for maintenance and providing for
inspections and certification may also be required.
Details of these requirements and instructions for preparing a BMP Operation and Maintenance Plan are
in Chapter 5 of the WQMP Guidance Document.

Conventional A type of BMP that provides treatment of stormwater runoff.
Treatment Control Conventional treatrnent control BMPs, while designed to treat
BMP particular Pollutants, typically do not provide the same level of
volume reduction as LID BMPs, and commonly require more
specialized maintenance than LID BMPs. As such, the 2010 SMR
MS4 Permit and this WQMP require the use of LID BMPs wherever
feasible,before Conventional Treatrnent BMPs can be considered or

� LID Bioretention BMP LID Bioretention BMPs are bioretention areas are vegetated (i.e.,
landscaped) shallow depressions that provide storage, infiltration,
and evapotranspiration, and provide for pollutant removal (e.g.,
filtration, adsorption, nutrient uptake) by filtering stormwater
through the vegetation and soils. In bioretention areas, pore spaces
and organic material in the soils help to retain water in the form of
soil moisture and to prornote the adsorption of pollutants (e.g.,
dissolved metals and petroleum hydrocarbons) into the soil matrix.
Plants use soil moisture and promote the drying of the soil through
transpiration.
The 2010 SMR MS4 Permit defines "retain' as to keep or hold in a
particular place,condition, or position without discharge to surface
waters.
LID Biotreatment BMPs that reduce stormwater pollutant discharges by intercepting
gMp rainfall on vegetative canopy, and through incidental infiltration
and/or evapotranspiration, and filtration, and other biological and
chemical processes. As stormwater passes down through the
planting soil, pollutants are filtered, adsorbed, biodegraded, and
sequestered by the soil and plants, and collected through an
underdrain.

Dear Mr. Walsh:
We have prepared this letter in response to the referenced "Review Comments" letter prepared by the
`� County of Riverside Planning Department dated December l, 2015. We have addressed the planning
department comments and for ciarification, we have reiterated the review comments followed by our
response.
ITEM 1:
Please provide a discus.sion vn the regional geologic settingfor the site.
RESPONSE ITEM 1:
The subject site is located in the southerly portion of the Perris Block, which is the central block of
three major fault-bounded blocks of the northern part of the Peninsular Ranges. The Perris Block
lies between the Santa Ana Block to the west and the San Jacinto Block to the east. The interior of
the Perris Block has various low bedrock mountains, hills and bedrock plains with intervening
sediment-filled valleys that make up six erosional surfaces sculpted by the effects of the vertical
oscillation of the block during the Plio-Pleistocene era.
Locally the subject site is located along the northerly edge of a southwesterly trending alluvial valley
(Pauba Valley), which is drained by Temecula Creek and its tributaries. Based on our subsurface
investigation, the subject site is underlain at the ground surface by approximately 35-ft of
undifferentiated alluvial/colluvial soils, which overly sedimentary units of Pleistocene-age Pauba
formation(Kennedy, 2000).

RESPONSE ITEM N�3:
Groundwater was encountered within ou�• exploratozy boring B-1 at a depth of 38-ft bgs, which was
excavated o�i the lower elevations of tlle subject sitc. Tlistoric high groundwater in the vicinity of tlle
subject site has been as high as 4-ft bgs in the vicinity of the subject site (DWR, I971 & Rancho
Wate�•, 1974). Histoz•ic l�igh �,n•oundwate�• was extrapolated fi•om wcll no. &S/2W-I?Gl, wllieh is
located approximately 600-ft to the northwest. Groundwater stabilized at a depth of 38-ft bgs duri»g
our subsurface investigation of the subject site. Based on the grawth of the Temecuta area and tlie
i��.creased den�ands on grouz�dwatei• welis tocated witliin the Pauba Valley, we do not anticipate
groundwater to aehieve historie highs.
Based on aur review of the previous liquefaction report pez•foz�m.ed for the co�atiguous property (same
awnership)to the east{Professional Engineez•s Consulting,Inc.,201 S), groundwater was stabiIized at a
depth of 37-ft bgs during their subsurface investigation of the subject site. Their liquefaction anaIysis
concluded that the subj�ct site was not susceptible to Iiquefactzon.
It is our apinion that, owing to the depth of shallow �roundrvater of approximately 38 feet bgs, the
proposed 5-ft thick f li blanket, and the silty nature of the n�edium d�nse to dense undifferentiated
alluvial/eoliuvial saiIs and sedimezztazy bed�•ock unde�•lyzng the subject site, lic}uefaction potential at
the subject site is anticipated ta be low,and further analysis appears ta be unwarranted at this timc.

RESPONSC ITEM N4 4:
The stateme��t was inadvertently left in fi•om previous report and should have read "liquefaction
patential at the subject site is anticipated to be low, and further analysis appears to be unwa��ranted at
this timc.
iTEM NO.5:
The cons•zrltrr�t should provrde the positivc lines vf'evidence (aer•ictl phvto analysis, site gevlogic
mapping, etc.) to support their conclassion that rao active f'at�lting tr•averses the site. Alsv, thc�
consultant should pf•ovide a cleccs•staterraent regai-din.g t.he fault ras��tuf•e��otenticr.l at dhe site.
R�SPONSE IT�M NO S:
Stereographic pairs of aerial photographs were examined to evaluate the local and regional geolo�;�c
and geamorphic features af the pz•opex�ty and iz�nn�ediate vicinity. Six {6} sets of vertical black and
white photos, dating from I939 were examined (see references). The photo�raphs were obtained from
the I'ai�•child Collection and Riverside County Plood Control Dist;•ict with scales of 1-in=1,667-ft
(I'airchiId}, 1-in=1,600-ft {1983 & 1990} and 1-inch=2,000 {I962, 1374 & 1980). Owing to the
z•elatively large pl�otogz•apl�ic scales invoIved, the a�lalysis and subsequent interpretatioz� of detail from
aerial pliotographs sometimes rcquiz•es a de�ree of subjective_judgnlent. The degree of cei�tainty on tt�e
interpretation of deiails depe�lds upon such factors as the scale aa�d tl�e quaIity of the photograph.
�iowever, an analysis of aeriat photog�•apl�.s will z•eveal tl�e gex�erai geomo�phic features, site
developrnei�t featu�•es, possible ground disturbance, etc. A summary of the obseived geoinorphic
sttuctures is provided belaw.
Topograpllically, the subject site is located near the northerly boundary of a la�•ge southwesi trending
alluvial valley in an area of gently sloping tez•rain toward Temecula Creek. No geomorphic
expressions suggestive of faulting, such as linear topo�raphy, affset streams, spring lines, and/or
fault scaips, were noted within or proximal to the subject site during our site investigation and
mapping and aerial photograph review of the subject site, A "tnoderate" linear expression was
noted approximately 5,000-ft southwest of the subject site and was defined by linear topo�raphy and
tonal changes in vegetation. This feature was roughly coincident with the n�apped location af the
Elsinore fault. A "made�•ate" lineament in the context of this report is an observed lineament that
may have Iocal sinuosity, is less than a few km lang, may be locally wider than long, is more diffuse
on imagery and may coincide with apparent alignments of topographic saddles or local drainage
se�;ments.

RESPONS� ITEM NO 6:
The closest known active fauit is the Elsinore fault zone(Tei�iecula segzi�eni} located approximately 5-
knn to the southwest of the subjeet site. The CaliFornia GeoIogical Survey has assigned tl�e Elsinore
fault zone(Temecula)a sIip rate of 5 mm/year, with probable magnitude of 6.8.
Other known si�ni�cant faults includc the San.lacinto fault(Anza segment} located appz•oxirnately 32-
km to the northeast of the site with a px•obabl�magnitude of 7.2. The Newport-Tnglewood fault]ocated
approximately 47-km to southwest of the subject site with a probable magnitude of 7.1. The San

City of Temecula, Riverside County, California
Work Order No. 2421502.00
Dear Mr. Stephen:
In accordance with your request, we have prepared this "Preliminary Geotechnical Investigation"
report for the proposed two-story o�ce building at the above referenced site. The purpose of our
�/ _ investigation was to evaluate the onsite conditions and provide foundation and grading
recommendations. Our scope of work included a site reconnaissance and subsurface exploration.
For our investigation, we were provided with a 15-scale "Preliminary Site Pian" prepared by The
Stephen Group (tsg) of Riverside, California. A reduced not-to-scaIe copy of the site plan was
utilized to prepare our Geotechnical Plan,Plate 1.
1.0 INTRODUCTION
Proposed Development& Site Description
The proposed development includes the construction of a two-story, office building with
associated parking, driveways and landscape areas. It is anticipated that the subject structure will
consist of conventional slab-on-grade construction utilizing continuous and pier footings.
The subject site (APN 959-080-005) is currently vacant and was previously utilized as a single-
family residence. At the time of our investigation, vegetation on the subject site consisted of a
sparse, low, dried growth of annual weeds and grasses. Topographically, the subject site is
located in an area of relatively flat terrain that slopes to the southwest at an approximately 2% or
less gradient. Drainage onsite is accomplished by sheetflow to the southwest toward Temecula
Parkway.

Fiefd Investi�ation
Three explaratory borings were advanced on September 24, 201 S to a tnaximum depth of 51.5-ft
below tlle ground surface (hgs) utilizing a Mobile Na. B-61 truck tnounted drill rig equipped with
6-in hollow stem augers. Logs of our exploratory boz•i��gs are included in Appendix B of this
report.
Laborato Testin Pro ram
Rep�•esei�tativc in-situ and bulfc soii sample were obtained from our expIoratory borings for
laboratory testing. Laborato�•y testing to determine the engineering paranrzete�•s of represe��tative
soils consisted of �naximum density/optimum mozsture determinations, moisture density
( determinations, expansion index, and sieve analysis including 20Q washes.
Laboratory testing was conducted in accordance with ASTM and Caltrans test speeifications, where
applicablc. The results of our laboratary tests are presented in Appendix C of this report.
SUBSURFACE CONDITIONS
B�sed on our subsurface investigation, thc suhject site is underlain at the ground su�•face by
appz•oxitnately 35-ft of uiid'zfferentiated aIluvial/colluvial soils, whieh overly sedimeiltaty units af
T'Icistocene-age Pauba foF•mation (Kennedy, 2000). The undifferentiated alluvial/colluvial soils
genez•alIy consisted of silty Sand (Uni�ed Soil CIassit"ication — SM} that can be described as
brown, �ne to medium �rained,minoi•gravel size, slightly moist with mznor to abu�idant pinpoi�it
pores and fine roots in upper 3-ft. Mino�• interbeds of dark brown clayey Silt {ML) and we11-
graded Sand (SW) were observed.
The sedimentary units consisted of interlensing gravelly silty Sand (SM-�P) and dark brown siIty
Sand (SM). The silty San.d (SM) can be described as medium to dark brown, fine to medium
gz•ained, minor gravel, nnoist and medium dense to dense. The sandy Silt (ML} can be described
as b�•own, medium dense, moist, and sandy in part, clayey in part with nainoz•calcat•eous veinlets.
The vs�ell-graded Sand (SW} at depth (45 feet bclow ground surface) can be described as light
brown, fine to veiy coarse grained sand with occasionat fine grained gravel. A more dctailed
description of the onsite earth materials axe presented in Appendix B, Explaratory Boring
Logs.

Groundwater
Groundwater was encountei•ed within our exploratory borzng B-1 ai a depth of 38-ft bgs, which was
excavated on the lower elevations of the subject site. Fluctuations of th.e �;roundwater level,
localized zones of pei•ched water, and variations in soils moisture content shouid be anticipated
during and following the rai�iy season. Irrigation of agriculture and/or landscaped areas on and
adjacent to the site can also cause a fluctuation of local groundwater ievels and perched water
conditions ean develop. In addition,the depih to groundwater can fluctuate seasonally as a result of
pIanned groundwater and ston��wate�•management.
Cxcavation Characteristics
We anticipate ti�at the undifferei3tiated alluvial/colluvial sails can be excavated witll nnoderate ease
ta moderate difficulty to the proposed depths utilizin�; conventional gradin�; equipment (CAT D-8
ar equivalent)in proper working conditian.
S�ISMICITY
Re�ianal Seismicitv
The site is located in a region of generally high seismzcity, as is all of southern California, During
its design life, the site is expected to expe�•ience strong ground motions from earthquakes on
F•egional and/or Incal causafiive faults. Tl�e subject site is not Iocated within either a Stat� of
California (Hart, 2000} or County of Riversid� (Gounty of Riverside GIS Webszte, 2015) Fault-
Kupture Hazard `Lo��e for active faulting. No active faults are k;iown to iz•avexse the site (Kennedy
& Morton, 2043}, 7'he closest knawn active fault is the Clsi�iore fault zane {Wildomar segmez�zt}
locatcd approximately witllin l.5-kilometers to the southwest of the subject site.
The EIsino�•e fault zoz�e (Wildomar segmez�t) is charactez•ized as a z•ig�zt-lateral strike-slip fault with
a total length of approximately 180 kiIometers (Caltech Southern Califarnia Earthquake Uata
Cente�• �scrne�, 20]5). The Caltech SC�DC has assigned the Elsinore fault zone {Wildoma�•) a
slip ratc of 4 mrn/year,with probable magnitudes of Mw 6.5-7.5.
2013 Califarnia Building Code(CBC}-Seismic Parameters:
Based on the geologic se�ting and soil conditions encountered, the soils underlying the site are
classified as "Site Class D, Stiff Soil Profile", according to the CBC. The seismic parameters
according to the CBC are summaz�ized in thc USGS Design Maps Sun�mary Report presented in
Appendix �. "The corresponding value for peak ground acccleration from the design response
spectrum based on the 2013 CBC seisznic parameters is 0.773g.

SECONDARY S�ISMIC HAZARDS
Lique�'actian
Soil liquefaction is the loss of soi] sti•ength due to increased pore water pressures caused by a
signifcant ground shaking{seismic) event. Liquefaction typically cozasists ofthe re-ai�•angeme��t of
the sail particles into a denser condition resulting, in ihis case, in Iocalized areas of settleznent, sand
boils, a.t�zd flow failures. Areas underlain by loose to medium dense cohesionless soils, where
graundwater is within 34 to 40 feet of the surface, are particularly susceptible when subject to
ground accelerations such as th.ose due to earthquake motion. Tlie liquefactioi; patential is
general]y considered greatest in saturated loose, poorly graded f ne sands with a nnean grain siz�
(D;o) in the range of 0.075 to 0.2z�t1��1. TypicalIy, liquefaetion has a relatively low potential at depths
greater than 45-ft and is vi��Eually unknown below a depth ot'60-ft.
Frocedures outlined in two publicatzozas, 1} The Guidelines for Evaluation and Mitigation of
Seismic Ha:�ards in Galifoz•nza, Special Fublication I 17: Department of Consex-vatior�, Division of
MiFaes and Geology {1997); and 2) Recomn�endations for Implementatioil of DMG Special
Publication 117: GuideIznes of Analyzing and Mitigation, Liquefaction Hazards in California:
Southern California Earthquake Center University of Southei�n California (1997), provide for a
' "screenzng study" in lieu of a coznplete liquefaction analysis. It is our opinion that, owing to the
depth of shallow groundwater of approxixnat�ly 38 feet bgs, the proposed 5-ft thick�Il blanket,and
the silty nature of the medium dense to dense undifferentiated alluviaUcoltuvial soils and
sedimerztary bedrock underlyin�;the subject site, liquefaction and other shallow groundwate�•related
hazards a�•e possible but not probable, an.d further analysis appears to be unwarranted at this time.
Seconda Seismic Hazards
Owing to tl�e absence of pi•e-existing faults, the medium dense to dense soils and sedimentaiy units
underlying the subject site,the relatively flat t�zature of the subjec#site, thc abs�nce of large sur�cial
boulders, and Iocation of the site in relation to large bodies af water; we at�tzcipate tlaat tlae potential
for ground �upture, seismic settlement, landslides, rock fall, seiches and tsunamis onsitc is
anticipated ta be ne�ligible.
RECOMMENDATIONS

As required by the 2013 California Building Code, Table 1705.6, it is recommended that
obscrvation and testing of fill procedures aspect of�;rading be canducted on a"continuous basis"as
lon�as f lI is bein�placed. This may requiz•e a high level of comn�unication and planning between
the testing personnel and the grading contractor.
Prior to the comznencernent of any grading, the subject areas proposed to be graded should be
cIeared of any vegetation, construction debris, undocun�ented fills, etc. The client, prior to any
si�e preparation, shouId arran�e and attend a rneeting among the grading contractor, the design
engineer, the soiis en�ineer and/oi• geologist, a representati�e of the appropriate governing
autl�orities as well as any other• concerned parties. AlI parties should be given at least 48 hours
notice. Eartl�wark shouId be conducted in accordance with the Standard Earthworlc and Grading
Speci�cations provided in A�pendix D,except where othe��wise specified in this report.
Site Preparation
Owing to the loose, potei�tzally compressible natu��e of the undiffez•entiated alluvial/colltYvial
soils, we z•ecommend thei�• complete rennoval and recaznpaction within any proposed structures.
The ovcrexcavation shouId be should extend a minin�um of 4-ft below the existin� ground
surface or a minin�unl of 2-ft b�low the bottom of the deepest footing, whichever is �;��eate�•. The
overexcavatio�3 shouId extend a minimuna of 5-ft outside the building footprint or to a distanee
equal to the ovez�excavation depth, whichever is greater. Removals within the pz•oposed driveway
and pai•king areas should extend a minimum of 1-ft below existing ground. The p�•oject soils
engineer and/or geolo�ist shouId verify the depth of any removals in the fieid prior to piacennent
of fll.
Prior to placemcnt of filI materials,the exposed alluvial soils sl�ould be scarified a minimum af 12-
inches bgs, rnoisture conditioned to near optin�um moisture coz�tent, and recompacted to a
miz�in�un� of 90-percez�t af thc maximum dry density as detcrmined by ASTM D-1557. The project
soils cngineer and/or geotogist oi• their representative should vea•ify tl�e deptli of any removals
and/or excavations ix� the field priar to placement o��ll.
Fill Placement
Onsite earth zxaaterials are suitable for use as stnzcturai fill. A qualzfied soil engineer should test
import materials to deterrz�.ine their feasibility for use as staructural fill. FiIC materials shall oniy be
placed on surfaces that are observed to be campetent alluvia�soils with minimum density of
85-percent of the maximum dry density as determined by ASTM D-1557.
Approved �lI material should be placed in 6 ta $-inch lifts, brought to at least optimuzn zn.oisture
content, and compacted to a minimum of 90 percent of the maxitnum laboratory dry dcnsity, as
determined by the AS"I'M U 1557-12 test method. No particles largez• thaz� 6 inches in diameter
should be used as fiil matez•ial. No asphalt concrete may be utilized as fill. Rocks Iar�;er than 6
inches should either be hauled off-site or ci•ushed and used as fill material and placed in
' _ accordance with specifications contained in Appendix D.

Cut/Fill Transitions
Owing to the recom.znencted ov�rexcavation and recompaction of th.e proposed building pad (see
Site Preparation Section), any cuf/�11 transitions are anticipated to be eliminated within the pad
areas.
Slope Stability & Construction
Cut and fill slopes canstructed at a 2:1 {horizantal:vertical) sIope i•atio, to a maximum vertical
l�eight of appraximately 10-ft, will be surficially and grossly stable if constructed in accordance
with the recommendations presented in this rcport and i�� Appendix D of this rcport. Owing to the
relatively flat nature of the subject site and tl�e "PreIiininazy Site Plan", no fill a��d/or cut slopes are
anticipated.
Exnansion Index Testin�
Expansion index testing was pez�farmed on a �•epresentative onsite sail sannple collected du�•in� our
izivestigation. The results, which are tisted iia Appendix C, indicate that the expansion index for
the onsite soiis is a 2, wl�ich is considered Non Expansive (Expanszon Irtdex <20 - 2013 CBC,
Section I803.5.3}. E�pansion testing should also be perform:ed on innpoz•ted soiIs priar to their
approval as structr�ral fi11 material az�.d on the pad surface at the completion of raugh grading
operations.
. ,,,, e Testin�
oluble Sulfat,,...
Based an oui• past soluble sulfate conient testing of simila�• soils on adjacei�t sites, it is antici�ated
that, from a cor�•osivity standpoint, Type TT Portla�zd Cement can be used for consti•uction. We
anticipate the onsite soils to have Negligible sulfatc exposure per 1�.mex�ican Concrete Institute
(�CI), 3I 8, Table 4.3.1 (2005). Soluble sulfate testing sltouId be conducted within tl;c huilding pad
az•eas at tl�e completion of grading.
Corrosion Suite Testin�
Based an our past Corrosivity Suite test results of sirrzilar soils on adjacent sites, we anticipate the
onsite soils ta be xnadex•ately cor��osive (NACE International, 1984). South Shore Testing and
Environmei�tal does not practice corrosion enginreex•ing. If specific information oi- evaluation
relatzng to the corrosivity of the onsite or any import soil is required, we recommend that a
coimpetent corrosion engineer be retained to interpret or provide additionaI con•osion analysis and
mitigation.

Allowable Bearins Cauacity
Ai1 allowable safe bearing capacity of 1,900 pounds per square foot(ps� may be used for design of
continuaus footings that maintain a mininnum width of 12-inches and a minimum depth of at least
12-inches below the lowest adjacent grade. The bearing value may be zncreased by 10% for each
additional foot of depth and/or width to a maximum of 2,3Q0 psf.
Total settlements under static Ioads of footings suppoi�ted on properly compacted �ll nnaterials and
sized for the allowable bearing pressures are not expected to exceed 1 inch. Differential settlements
between footings designed far the maximutn recon�mended bearing value are expected to be less
than one-haif of the total settlement. These settlements are expccted to occur primarily duz•ing
construction. Soil engineering parameters for imported soil ix�;ay vary.
Lateral Load Resistance
Tl�e foIlowing parameters should be considered foa• lateral Ioads against peirnanent structures
founded on en�inee�•ed fill nlaterials compacted to 90 percent of the nlaximum dzy density. Soil
en�;ineering parameters foz•imported soil may vary.
�;quivalent�'luid Pressure for Leve1 F3ack#ill
Active: 35 pcf
Passivc: 327 pcf
Coefficient of fi•iction(concrete on soil}: 0.35
If passive earth pressure and fz•iction arc combined to provide required ��esistat�ce to lateraI fo��ces,
the value of the passive p�•�ssure should bc reduced to two tl�irds of the above recommendations.
These values may be increased by one tlziz•d whei� considerin; short-term loads such as wind oz•
seismic forces.
Foundation Svstem Desi�n
Foundation elements for any pz•oposed structures should be fauiaded entirely in engineered �11
materials. South Shore Testing & Environmental should perform a footing inspection, prior to
placement of reinforcem�nt to insuz•e the footing excavations and reinfo�•cement have been
constructed in aecordance with the recannmendations presented in this report.
For one-story or equivalent structures, contznuous spread foatings should be a mininaunn of 12-
inches wide and 12-inclaes �elow the Iowest adjacent grade. Fo�•two-sto�y or equivalent struc#ures,
continuous spread footings should be a minin�urn o#'I S-inches wide and 18-inches below the Iowest
adjacent�;rade. As a minimurn, ail footings should have two No. 4 reinfo��cing bar placed at the top
and bottom of the footing.

The slab area ar�d footing excavations shauld be moistened prior to placement af concrete.
Concrete siabs should be a minimuzn thickness of 4-inches. Conerete sIabs, in moisture sensitive
areas, shoutd be underlain with a vapor barrier consisting of a minimum of 10-mil polyviiiyl
chloride membra�le with all laps sealed. A 2-inch laye�•of clean sand should be placed above the

4bse�rvation of Foundation �xcavations
In accordance with the 20I3 C�3C and prior to the placement of fozms, coz�crete, or steel, all

It is recozrxnnended that thc subgrade materials be compacted ta a depth of I foot below
subgrade elevation and that both the sub�;rade matet•iais and the�BII be compacted to 95%
relative to the znaximum density of the respective matez•ials, as detexmined by ASTM
D l 557 laboratozy tests. R-Value testing should be conducted on imported soils prior to
their approval as structural fill material
Surface Drainase
Proper surface drainage is cz•itical to the future perfarmance of the project. Infiltx•ation of irz•igation
excess and stox•n� runoff into the supporting soiIs can adve�•sely affect the pez•fo�-mance of the
planz�zed improvements. Saturatzon of a soil can cause it to lose internal sl�ear strength and increase
its eampressibility, resulting in a chai��;e in the original designed en�;ineering propez�ties. Proper
drainage should be maintained at all times. All site drainage should be collected and transferred to
the street in non-erosive draina�e devices or onsite in approved infilt�•ation systems. Drainages
should not be allowed to pand anywhe�•e on tlZe site, and especially not against any foundation o�•
retaining wall. Landscape irrigation situated within 5-ft of thc building perimeter shauld be
enclosed in protected planters.
Positive site drainage should be provzded away from structures, pavement, and the tops of slopes to
swales or other approved nan-erosive drainage structures. Any buitding pad and pavement areas
should be fne graded such that water is not allowed ta pond.
Oversize Rock
No ovex•szze rack was obse;ved du��ing ou�•investigation of the subject site. Ii'any oversize n�.aferial
is to be generated during site development, it shouId be disposed of off site, utitized in landscapin�,
or placed in a��approved rock fill in accordance wi#h Appendix ll of tl�is repoi�t.
Utility Trench Back�ll
Utiliiy trench backfill should be compacted to a zninimum of 90 percent of the maximunl dry
density determined in laboratory testing by the ASTM D 1557 test n�ethod, It is our opinion that
utility trench backfill consisting of onsite or approved sandy soils can best be placed by mechanical
compactio�l to a minimum of 90 percent of the rr�axi�nuni dxy ciensity. The upper 1-ft of utility
trench excavations located within pavement areas should be cozzzpacted#o a rz►ininr�urrx of 95 percent
of the maximum dry density. All trencl� excavations should be conducted in accordance with Cal-
USHA stazldards as a minimum.

The soils encountered within ouz•exploratory trenches are generally classiffed as Type"C" soil in
accordance with the CAL/OSHA (California, State of 2007) excavation standards. Unless
speci�cally evaluated by the project engineering geologist, all tempora�y excavations should be
performed in accordance with CAL/4SHA (California, State of, 204'7} excavation standards for
Type "C" soil. Based upon a sail classi�cation of Type "C", the temporary excavations should
not be inclined steeper than 1.5:1 (horizontai:vertical) for a maximum depth of 20-ft. For
temporary excavations deeper than 20-fi or for conditians that differ fron:z those described for
Type "C" in the CAL/OSHA excavation standards, the project geotechnical engineer should be
contacted.
Grading Plan Review

LAB�RATORY TESTING
A. Classificatio�
SoiIs were visually cIassificd according to the Unified Soil Classzfzcation System.
Classi�cation was supplemented by index tests such as maxi�num density and optirnum
moisture can#ent.
B. Ex ansion Index
An expansion index test was perforn�ed on a repz•esentative sample of the onsite soils
remolded and tested under a surchar�;e of 144 lb/ftz, in accordance with ASTM D-4829-
11. "I'he test results are presented on Figure G1, Table I and a copy of our labo►�atory
test ►•esults are presented on Figure C-2.
C. Maximum Density/Ot�timum Moisture Content
A maximum density/optzmum moisture content �•elationship was determined for typica]
sample of the onsite soils. The laboratoiy stai�da�•ds used we;i•e AS"I'M 155'7-Method A.
The test x•esults are summarized on Figure C-1, Table YI and laboratary results are
p�•esented on Figure G3.
� � D. Particte Siz�Determination
A paz�tiele size deterrr�ination, consistin�; of inechanical analyses (sieve} inciuding 20�
washes was perforined on rep�•esentative samples of th� onsite soils in accordance with
t�STM D 422-63 and CAI, 'TEST 202. The test resuits are shown on Figure C-4 and the
z•esults of the 200 wash testin�; a�•e px�esented on the Exploratoxy Boring Log in

SECTION I.
EXECUTIVE SUMMARY&RECOMMENDATIONS
Earth-Strata, Inc. (E-S)was retained by Mr. Kevin Fox to perform a Phase I Site Assessment
(Phase I ESA) of a site located at 31625 De Portola Road, Temecula, California. At the time
of the October 7th, 2015 site visit,the subject property consisted of one parcel, with a single
story 2,000 square foot house totaling approximately 2.23 Acres. The subject property is
located within a residential area.
This Phase I ESA was performed in accordance with the scope and limitations of the
American Society for Testing and Materials (ASTM)Phase I ESA Standard E1527-2013
(equivalent to the USEPA's All Appropriate Inquiry [AAI] Standard),the scope of work
defined in this report, as well as the signed service agreement. The following summarizes E-
S's independent conclusions and best professional judgment based upon information available
to us during the course of this Assessment.
During the site visit, the E-S Assessor was accompanied by Mr. Don Rhodes, on site resident
for over 10 years. Mr. Rhodes said the property has always been a residential single family
home with no UST's,AST's or industrial usage. The home is currently vacant, and the yard is
used for Mr. Rhodes landscaping business.
As defined by ASTM E1527-2013, the Key Site Manager is that person having good
knowledge of the uses and physical characteristics of the subject property, and in a position to
provide reasonably accurate information far the Key Site Manager Environmental
Questionnaire. The questioner was performed Earth Strata.
Based upon the limited site reconnaissance, historical review, regulatory records review, and
other information detailed within this report, this Assessment identified evidence of pesticide
use, an ASTM Recognized Environmental Conditions (RECs). No other issues in connection
with the subject property were recognized.
RECOMMENDATIONS
Based on the results of this Phase I ESA, no further investigation is recommended for this
Site.
An Executive Summary Overview is also included in the previous section. However, when
making any decisions concerning the findings of this Assessment, please also refer to the
entirety of this report, which may present other items of interest that are not discussed in the
Executive Summary, or further details regarding the above items. In addition, please refer to
the Data Gaps section (IV-H) of this report regarding information that may have been
unavailable or incomplete which may have a bearing on the findings or usage of this report.

SECTION II.
SCOPE OF WORK&LIMITATIONS
PURPOSE
The primary goal of this Phase I Environmental Site Assessment is to assist the client in
satisfying one of the requirements to qualify for the "innocent landowner, contiguous property
owner, or bona fide prospective purchaser limitations on CERCLA liability" (42 U.S.C. §
9601 et. seq.). Qualification for these limitations is predicated on the assumption that "...the
defendant must have undertaken, at the time of acquisition, all appropriate inquiry into the
previous ownership and uses of the property consistent with good commercial or customary
practice in an effort to minimize liability...." The secondary goal of this Assessment is to
provide information that will assist in evaluating the risk of potential significant value
impairment of the security interest due to environmental impacts.
PROTOCOL
The American Society for Testing and Materials (ASTM) Phase I ESA Standard E1527-2013
is the most current method used in attempting to perform the due diligence required to achieve
the above purpose. The E1527-2013 Standard was created by the ASTM "...in an effort to
define good commercial and customary practice in the United States of America for
conducting an environmental site assessment...." and is equivalent to the USEPA's All
Appropriate Inquiry [AAI] Standard issued November 1, 2013. The ASTM Standard E1527-
2013 is the revised E1527-2005 and is intended to identify recognized environmental
conditions (RECs) in connection with a given property. The term recognized environmental
conditions is not intended to include "de minimus" conditions that generally do not present a
material risk of harm or that are unlikely to be the subject of enforcement actions by
governmental agencies. Other conditions or issues that are beyond the ASTM scope may also
be discussed in this report, as detailed within each section.
SCOPE OF WORK
Utilizing ASTM Standard E1527-2013, as well as the scope of work discussed below and in
the work authorization document, this Assessment involved: A site reconnaissance of the
subject property, review of Phase I by others, limited observations of adjoining properties, a
review of the historical usage of the subject property, and a review of relevant documentation
provided by various public and private sources (including the client and/or owner of the
subject property) to identify conditions indicative of releases or threatened releases of
hazardous substances, as defined in CERCLA Section 101 (14)U.S.C. § 312.1(c) evaluate the
presence or likely existence of:
♦ Recognized environmental conditions, specified by ASTM E1527-2013 as: "the
presence or likely presence of any hazardous substances or petroleum products on
; a property under conditions that indicate an existing release, a past release, or a
_�
Phase[Environmental Site Assessment Earth-Strata,Inc.
31625 De Portola Road,Temecula,CA Page 6
��,
' material threat of a release of any hazardous substances or petroleum products
into structures on the property or into the ground, groundwater or surface water of
the property."
♦ A brief evaluation and assessment of potential environmental issues which may
not rise to the level of recognized environmental conditions, such as: obviously
improper hazardous material or waste handling, suspect asbestos-containing
materials, lead-based paint, polychlorinated bi-phenyls, and radon gas.
LIMITATIONS
As discussed in ASTM E1527-2013, no Phase i ESA can completely eliminate uncertainty
regarding the potential for RECs in connection with a subject property. This investigation is
simply intended to reduce uncertainty within reasonable limits of time and cost.
Refer to Section VI-A for a brief discussion of some (but not necessarily all) specific
limitations to E-S's subject property observations at the time of the site visit. The
observations contained within this Assessment are based upon conditions readily observable
during the site visit. These observations are typically unable to address conditions of areas not
inspected, hidden from view, subsurface soil, groundwater, underground storage tanks,
neighboring properties, and the like, unless specifically mentioned. It is not the purpose of
this Assessment to determine the actual presence, or degree or extent of contamination (if any)
at the subject property. Unless specifically noted within this report, this Assessment does not
include observations, testing, coring, or sampling analysis to address groundwater, soil, or
extraneous materials contamination (including mold, bio-hazardous or radiologic issues) in or
on the subject property. E-S also is not providing geological interpretations or
recommendations. Potential Vapor Intrusion issues from on or off-site sources are not
evaluated. Electromagnetic issues (e.g., proximity to high-voltage power lines) are also not
included. This Assessment does not include or address reasonably ascertainable
environmental liens recorded against the subject property, unless stated.
E-S makes no warranties or guarantees as to the accuracy or completeness of information
obtained from or compiled by others. Information may also exist which was beyond the scope
of this investigation, or was not provided to E-S that may have an impact on the conclusions
of this Assessment. This Assessment does not attempt to address past or forecast future site
conditions. E-S also cannot forecast or be responsible for changes in regulatory guidelines or
protocols, industry standards or the like, which may affect the conclusions and/or future usage
of this report.
This Assessment has been conducted and prepared in accordance with generally accepted
practices and procedures exercised by reputable professionals under similar circumstances. E-
S makes no other warranties or guarantees, either expressed or implied, as to the findings,
opinions, or recommendations contained in the report, or as to the existence or non-existence
of RECs or other issues at the subject property.

SECTION III.
GENERAL SITE DESCRIPTION
Earth-Strata, Inc. (E-S)was retained by Mr. Kevin Fox to perform a Phase I Site Assessment
(Phase I ESA)of a site located at 31625 De Portola Road, Temecula, California. At the time
of the October 7th, 2015 site visit, the subject property consisted of one parcel, with a single
story 2,000 square foot house totaling approximately 2.23 Acres. The subject property is
located within a residential area.
During the site visit, the home is vacant but the property is occupied by Mr. Rhodes, who runs
a landscaping business with several tools, pieces of equipment and landscaping remnants on
site. The site is fenced,with parking and storage areas. Some of the fencing has been knocked
down, several small storage buildings and two storage containers are near the back half of the
property. Dirt has been stock piled in the middle of the property. Power and water lines run
underground along De Portola Road. A septic system is located in front of the house, between
the structure and De Portola Road. A small intermittent natural drainage runs north to south
along the west side of the property and is improved with riprap. The subject property location
is shown on various Figures in the appendices.
A. CLIENT PROVIDED INFORMATION
As discussed in ASTM E1527-2013, the user(e.g., Client) is required to perform certain tasks
or provide certain information to E-S in order to identify potential RECs. Tasks or
information to be provided by the Client include: 1) review of judicial and title records for
environmental liens,environmental deed restrictions or activity and use limitations (AULs);2)
provide specialized, actual, commonly known or reasonably ascertainable knowledge
regarding the property; and, 3) identify reasons for a significantly lower purchase price (if
applicable).
The Client has not provided or reported to E-S any information which indicates the subject
property is being sold, purchased or valued at a significantly reduced price due to outstanding
environmental issues. Nor has the Client or Key Site Manager provided or reported to E-S
information indicating a specific knowledge of RECs, historic RECs, Environmental Liens,
Activity and Use Limitations, or Environmental Deed Restrictions related to the subject
property.
However, E-S was not privy to the original purchase price versus valuation metrics of the
property by the current owner/seller, and therefore cannot evaluate this parameter. The
Client/User of this report may wish to perform such an evaluation.

B. ADJOINING AND ADJACENT PROPERTIES
As discussed in ASTM E1527-2013, an adjoining property is any real property whose border
is contiguous or partially contiguous with the subject property, or would be if the properties
were not separated by a roadway, street or other public thoroughfare. For the purposes of this
report, an adjacent property is any real property located within approximately one block or
less of the subject property's border.
Specifically,the subject property is bordered by the following:
North: Immediately by De Portola Road, Vacant Lots and single family
residential properties.
East: Immediately by Vacant properties and Margarita Road.
West: Immediately by Vacant property.
South: Immediately by a Hospital.

C. USGS TOPOGRAPHIC MAP
The subject property's physical setting was researched employing a United States Geological
Survey (IJSGS) 7.5 Minute Topographic Quadrangle (Quad) Map relevant to the subject
property. The USGS 7.5 Minute Quad Map has an approximate scale of 1 inch to 24,000 feet,
and shows physical features such as wetlands, roadways, mines, and buildings. The USGS 7.5
Minute Quad Map was used as the Standard Physical Setting Source, and is sufficient as a
single reference.
The Pechanga, California Quad Map shows no physical features that are likely to
environmentally impact the subject property. The subject property is identified as a
rural/urban large property with three buildings. No mines, aboveground storage tanks, or
wetlands were depicted in the immediate area of the subject property; however there is a blue
line ending at the property front of the property indicating a waterway. The elevation of the
subject property is approximately 1065 feet above mean sea level with a gentle topographic
gradient to the south (USGS Pechanga 7.5' Quadrangle). A copy of the map can be found in
appendix B.
D. GENERAL HYDROGEOLOGIC CHARACTERISTICS
The subject property is within the Temecula Valley Groundwater Basin, underlying the Santa
�' Margarita water shed. The Temecula Valley Groundwater Basin underlies several valleys in
- the southwestern portion of Riverside County and northern San Diego County. Murrieta,
Temecula, Pauba, Long, and Lancaster Valleys are largest of the valleys overlying this basin.
The basin is bounded by non-water bearing crystalline rocks of the Peninsular Ranges. The
overlying valleys are drained mainly by Wilson, Temecula, Murrieta, Warm Springs, and
Pechanga Creeks,to the Santa Margarita River, which flows west out of Temecula Valley.
The Pechanga Indian Reservation overlies some of the southwestern part of the basin.
Average annual precipitation ranges from 7 to 15 inches. (Department of Water Resources
(DWR) 1956).
Water bearing formations consist of Quaternary alluvium, which is estimated to reach more
than 2,500 feet thick, and is the water-bearing material of this basin. Well yields generally
range to 300 gpm in the northwestern part of the basin, but reach 1,750 gpm for wells in
Pauba Valley(DWR 1956). Groundwater is generally unconfined, but is confined in the Pauba
Valley and near some faults that cut the basin (DWR 1956).
Although site-specific groundwater information for the subject property was unavailable,
according to information obtained from the EDR report the closest well site is(Federal Well
ID USGS40000133968). Groundwater flow direction beneath the site is not provided. Please
see the EDR Summary Radius Map Report for Hydrologic and Geologic information,
appendix D.

SECTION IV.
HISTORICAL REVIEW
The site historical review is used to develop an understanding of the previous uses of the
subject property and surrounding area in an effort to identify the likelihood of past uses, or
activities having environmentally impacted, the subject property. The historical review
consisted of a search of various public and private Standard Historical Sources, as detailed in
the sections below.
As defined by ASTM E1527-2013, a Standard Historical Source is considered complete if the
information contained within the source identifies all uses of the subject property from the
time the property was first used for residential, agricultural, commercial, industrial or
governmental purposes. Ideally, the information should be available in either five-year
intervals or site milestone events (i.e., initial construction activities, demolition activities,
etc.). However, available public and private historical sources do not always fulfill this goal,
in which case, the closest approximation is made based upon the sources readily available at
the time of historical review.
Historical Review Summarv: From the historical information review discussed below, E-S
concludes that the subject property was initially developed in 1985 with wood frame structure,
primarily used for residential purposes. The structure has been occupied by multiple tenants
since its construction. No dry cleaners, gasoline stations, major landfills, military bases, or
heavy industrial businesses were identified on the subject property. Currently the site is used
for residential purposes.
A. AERIAL PHOTOGRAPH REVIEW
Aerial photographs were reviewed by E-S to evaluate past land-use patterns of the subject
property and vicinity on a 10 year basis going back to 1939. The photos were supplied by
EDR and Google Earth Pro. Copies of representative aerial photographs can be found in the
appendix. This review revealed the following:
1939 to late 1980:
The subject property is in a rural area, agriculturally developed with tilled fields. The
surrounding area usage consists of vacant natural vegetation and rural agricultural
land. De Portola Road appears in the 1978 aerial photo.
1985 to Present:
The subject property appears developed with a single story home in the 1989 Aerial
Photo. The surrounding area usage increases with large residential properties roads
and various infrastructures that accompany it.
Phase I Environmental Site Assessment Earth-Strata,Inc.
31625 De Portola Road,Temecula,CA Page 1 I
B. BUILDING PERMIT REVIEW
In an effort to evaluate the development history of the subject property, E-S reviewed the
Riverside County, Department of Planning website (http://www3.tlma.co.riverside.ca.usn.
Review of this information indicated 1 Assessor's Parcel Number for the subject property.
The measured area for the parcel is approximately 2.23 acres. The legal description is located
in the appendices, Thomas Bros. page 979, grid E2, Township and Range is T8SR2W SEC
17. No other information significant to this report was obtained from the Assessor's data.
The data for one typical parcel can also be found in the appendix E.
C. SANBORN FIRE INSURANCE MAP REVIEW
E-S requested Sanborn Fire Insurance Maps for the subject property; no maps were found.
D. CITY STREET DIRECTORY REVIEW
E-S requested a "City Street Directory" for the area of the subject property. No significant
additional information was revealed after review.
E. HISTORICAL TOPOGRAPHIC MAP REVIEW
�
Historical topographic maps were provided by EDR and reviewed by E-S. No significant
additional information was revealed after review.
F. INTERVIEWS
As specified in ASTM E1527-2013, interviews will be conducted with parties including
present land owners and occupants, past land owners and occupants, and adjoining property
owners, as appropriate and as available. E-S interviewed the land owner, at the time of the
site visit; no environmental issues were identified by the owner.
G. RECORDED LAND TITLE RECORDS
As specified in ASTM E1527-2013, recorded land titles are records usually maintained by the
municipal or county recorder of deeds which detail ownership fees, leases, land contracts,
easements, and other encumbrances attached to or recorded against the subject property. Due
to state land trust regulations and laws, land-title records typically only provide trust names,
owner's names, or easement holders, and not information concerning previous uses or
occupants of the subject property. Therefore, this Assessment has relied upon other standard
historical information sources which are typically more informative than recorded land titles.
The Client also has not provided an environmental liens/activity usage limitation search for E-
S's review, or requested that such a search be performed by E-S. According to the ASTM
Phase[Environmental Site Assessment EaRh-Strata,Inc.
31625 De Portola Road,Temecula,CA Page 12
E1527-2013 guidelines, it is the responsibility of the User of this report to perform such a
review.
A title report was not provided, however a search was conducted on-line at the Riverside
County Land information site (http://www3.tlma.co.riverside.ca.us/pa/rclis/index.html). Such
a report typically does not list all documents related to the subject property, simply those that
the title insurer wants to exclude from coverage and/or that are of potential interest to the
transaction. Title reports may also be one method to evaluate the environmental liens search
required by the ASTM E1527-2013 standard, which is required to be performed by the report
User. A liens/use limitations search by the User is required by the ASTM/AAI standard 180
days or less prior to acquisition of a property, but a general review of the above title report
was performed by E-S.
No obvious issues that would significantly environmentally impact the subject property were
noted from this review. In addition, no environmental liens, environmental deed restrictions,
nor activity and or use limitations related to environmental issues were specifically listed.
Please note that E-S has not reviewed the underlying documents related to the items listed in
the title report, and the purpose of the items was only generally ascertained based on their
listed document name. E-S also did not review the title report for potential non-
environmental issues that may affect the property, and is not providing a legal opinion as to
the contents of the report. If more in-depth information is desired regarding the contents of
the title report, appropriate legal counsel or a title professional should be consulted.
r"
H. DATA GAPS
As specified in ASTM E1527-2013, data gaps are defined as "a lack or inability to obtain
information required by the standards and practices listed in the regulation despite good faith
efforts by the Environmental Professional or prospective landowner to gather such
information". Data failure occurs when historical research does not identify standard
historical sources that are "reasonably ascertainable" and"likely to provide useful information
to identify prior uses of the property". Per ASTM E1527-13, the assessment must document
data failure and give reasons why historical sources were not available or excluded (if
applicable). Based on E-S's research, no significant data gaps were identified for the subject
site.

�� ' SECTION V.
AGENCY RECORDS REVIEW
In an effort to evaluate whether the subject property and/or nearby sites have reported USTs,
hazardous waste generation, or hazardous material releases, regulatory information from the
federal, state, and local agencies listed below were reviewed. The database report was
compiled by a third-party database provider and is reportedly the most recent database
information available from each agency. A copy of the database report is included in the
appendix. According to the database provider, their search of the various databases conforms
to ASTM E1527-2013 Standards. However, the accuracy of the information provided by the
agencies is not without error or omission, and the information listed is limited to that which
was reported to or gathered by that agency. A limited discussion of the number of sites
identified, and of their potential impact to the subject property, follows this page. In addition,
E-S may request state and/or local regulatory agency information for the subject property,
targeting those agencies most likely to provide information useful for this Assessment. The
primary databases reviewed and their general search range criteria are below:

"Orphan" sites are those which could not be plotted by the database provider using
conventional geo-coding methods, typically because the information provided in the original
government database was unclear, incorrect or missing. A listing of orphan sites (if any)
appears at the end of the database, immediately after the last plottable site description.
E-S reviewed the orphan list for sites with the same name as the subject property(if applicable)
and/or the same or similar property address. This review is inherently limited by the
incomplete and/or possibly incorrect data reported in the orphan listings. For orphans
apparently not related to the subject property, only those obviously located adjoining or within
a short distance that may affect the property are discussed. Orphan sites which are also listed in
the plotted section are not re-discussed. E-S's review of the orphan list revealed no obvious
sites of concern listed at or adjoining the subject property.

OTHER POTENTIAL ISSUES OF CONCERN
A. PCB-CONTAINING EXTERIOR ELECTRICAL TRANSFORMERS
No electrical transformers was observed near the subject.
B. OTHER PCB-CONTAINING INTERIOR OR EXTERIOR EQUIPMENT
During the on-site inspection, no evidence was observed of any equipment likely containing
PCB-contaminated fluid (e.g., interior electric transformers, hydraulic elevators, hydraulic
hoists/lifts, hydraulic loading dock ramps, other fluid containing equipment, etc.).
C. SUSPECT ASBESTOS-CONTAINING MATERIALS (ACMs)
Due to the age and nature of the property the buildings may contain asbestos materials;
however, no observations of asbestos-containing materials (ACMs)were identified.
D. LEAD-BASED PAINT (LBP)
Due to the age of the of the property it's unlikely that LBP's may be present: However, no
i observations of lead-based paint(LBP)were observed.
E. LEAD IN DRINHING WATER
Federal regulations limit lead in publicly supplied water to no more than 15 parts per billion
(ppb), however, the most common source of lead in tap water is from interior plumbing
systems (piping, connections, faucets, etc.). Children are the most susceptible to possible
health effects from consuming lead-tainted drinking water. Due to the nature of the property
being undeveloped, no observations of these sources were observed. The presence or absence
of elevated lead concentrations in the water can only be confirmed through laboratory testing,
and such analysis is beyond the scope of this Assessment.
F. AIR QUALITY
Unusual smells, noxious odors, or visual emissions were not observed during the inspection of
the subject property. However, these observations are general in nature and should not be
construed as an air quality assessment.
��
Phase I Environmental Site Assessment Earth-Strata,Inc.

/��
G. RADON
According to the USEPA, the general area of the site has a predicted average indoor screening
level of less than the EPA guideline action level of 4.0 picoCuries per liter of air(EPA Radon
Zone Level of 2 or 3). Therefore, based upon the reported subsurface characteristics of the
area, the subject property exhibits a low to moderate potential for high-level radon exposure.
H. RAILROAD RIGHTS-OF-WAY
There are several potential environmental risks associated with railroad rights-of-way,
including the usage of herbicides, pesticides, petroleum materials and related heavy metals
(e.g. arsenic) to maintain the tracks, as well as the potential spillage of hazardous materials
from railcars. During the site visit, railroad rights-of-way, spurs, or related features were not
observed near the subject property.
I. PESTICIDES
During this assessment, agricultural pesticide use was not identified.

�-, Infiltration Trench Desi�n Procedure
1. Enter the area tributary to the trench, maximum drainage area is 10 acres.
2. Enter the Design Volume, VgMp, determined from Section 2.1 of this Handbook.
3. Enter the site infiltration rate, found in the geotechnical report.
4. Enter the factor of safety from Table 1 of Appendix A, Infiltration Testing.
5. Determine the maximum reservoir layer depth, DMAX, The value is obtained by taking the
smaller of two depth equations but may never exceed 8 feet. The first depth, D1 is related
to the infiltration rate of the soil. The second depth, D2, is related to required setbacks to
groundwater, bedrock/impermeable layer. These parameters are shown in Figure 1.
Calculate D1.
1(in�hr) x 72 (hrs)
\
Dl 12�tin�ft� X n�100 x FS
� � Where:
� I =site infiltration rate (in/hr), found in the geotechnical report
FS =factor of safety, refer to Appendix A- Infiltration Testing
n = porosity of the trench material, 40%
Calculate DZ. Enter the depth to the seasonal high groundwater and
bedrock/impermeable layer measured from the finished grade. The spreadsheet checks
the minimum setbacks shown in Figure 1 and selects the smallest value. The equations
are listed below for those doing hand calculations.

= Depth to historic high groundwater mark- 11 feet
= Depth to impermeable layer- 6 feet
DZ is the smaller of the two values.
DMAX is the smaller value of D1 and DZ, and must be less than or equal to 8 feet.
6. Enter the proposed reservoir layer depth, DR. The value must be no greater than DMAx•

;-�,, 7. Find the required surface area of the trench, AS. Once DR is entered, the spreadsheet will
calculate the corresponding depth of water and the minimum surface area of the trench.
Design d�,t, = DR x �n�100� AS = vBMP
Design du,
Where:
AS = minimum area required (ftZ)
VBMP = BMP storage volume (ft3)
Design dW = Depth of water in reservoir layer (ft)
8. Enter the proposed design surface area; it must be greater than the minimum surface
area.
9. Calculate the minimum trench width. This is to ensure that EPA's Class V Injection well
status is not triggered. The total trench depth (shown in Figure 1) includes the upper foot
where the overflow pipe is located. The minimum surface dimension is DR+ 1 foot.

OPERATIONS AND MAINTENANCE MANUAL
A. Purpose
The purpose of this manval is to provide maintenance instructions for the infiltration trench
located northwest side of the building. The infiltration trench treats urban runoff before it enters
into the onsite storm drain system. Maintenance per this manual will ensure the infiltration
trenches function as designed.
This manual will serve as a reference guide to assist the property owner with the following:
1. Overview of the infiltration trench and planter box and how they function
2. Description of the location of the infiltration trench and planter box
3. Procedure required to effectively maintain the infiltration trench and planter box
4_ Reproducible copies of the forms, logs,and guidelines necessary for recording
maintenance activities associated with the infiltration trench.
B. General Description and Function of the Infiltration Trench and PIanter Box
Infiltration Trench
The infiltration trench is a 177'by 20'basin that is 1'deep on the surface and 3'deep under the
sarface that allows urban runoff to infiltrate into the ground. From the top of the trench to the
bottom the material consists of:
�. 1. Mulch or landscape material on top
2. 1'of pea gravel �
3. 2'of washed rock(1"to 3"diameter)
4. Tmpermeable liner on the sides of the trench

The basin contains an overflow outlet with an 8"pvc pipe that connects to an I 8"pipe from the
Temecula Medial O�ce Building project. The 18"pipe ties into an existing storm drain in
Margarita Road.
Runoff is treated by passing through•the pea gravel and rock within the trench and ultimately
through infiltration into the ground under the trench.
Planter Box
The planter box is 10'x 160'x 0.5'deep with an outlet that is 4"off the bottom of the planter.
The outlet pipe is 6"pvc and ties into the infiltration trench.See diagram below:

C.Maintenance Responsibility .
The property owner,TV Phase One,LLC is responsible for maintaining the infiltration trench
and planter box. The goal of maintenance is to ensure that infiltration is occurring. Regular
inspection and replacement of materials within the trench and planter box once they become
ineffective in performing as designed are the major components in the maintenance program.
Trash, litter,and debris will also need to be removed on a regular basis. The following general
procedures should be followed:
. 1. Qualified maintenance personnel should periodically inspect the trench and planter box
every 6 months.
2. If a problem is identified, it should be resolved as soon as possible to ensure that the
trench and planter box function as designed.
3. Regular removal of trash and debris should occur.Any visible trash or debris should be
promptly removed.
Detailed maintenance procedures are outlined in Section E
D.Maintenance Indicators and Activities
Functional Maintenance �
Regular functiona!maintenance is required to ensure that the infiltration trench and planter box
perform in an effective manner. Functional maintenance consists of both preventative and
� corrective activities. Logs and guide sheets are contained herein to use in recording vital
information while performing operation inspection and other infiltration trench and planter box
maintenance activities. Maintenance records shall be kept by the property owner for a minimum
of 5 years. The proper use and subsequent storage of these records will assure.the City of
Temecula that the infiltration trench and planter box are functioning as designed.
Preventative Maintenance
Preventative maintenance shall be performed on a regular basis. Checklists are included herein
to track and record preventative maintenance activities. These activities include trash and debris
removal and sediment management.
Trash and debris removal shall be performed to ensure that runoff has adequate surface area to
infiltrate through the various layers that comprise the cross section ofthe trench and to ensure the
planter box functions properly.
Sediment management will occur when testing indicates that the infiltration rate has diminished
below the stated acceptable rate.
Corrective Maintenance •
Corrective maintenance will be required on an emergency or non-routine basis to correct
problems and restore intended operation and safe function of the infiltration trench and planter
box.

Infiltration Trench Maintenance
1. Inspect minimum of twice per year, before and after the rainy season, after large storms or
mbre frequently as needed.
2. Clean the trench when the loss of infiltration capacity is observed. When standing water
is present for a period of time in excess of 72 hours,removal of sediment may be
necessary.This is an expensive activity and the need for it may be minimized through the
prevention of erosion.
3. Control mosquitoes as necessary
4. Remove litter and debris from surface as required
Planter Box Maintenance
1. Inspect minimum of twice per year,before and after the rainy season,after large storms or
more frequently as needed.
2. Clean the planter box when the loss of function is observed. When standing water is
present for a period of time in excess of 72 hours, removat of sediment may be necessary.
This is an expensive activity and the need for it may be minimized through the prevention
of erosion.

planter box maintenance activities.Emergencies that occasionally arise would require a more
urgent, critical response.
Sediment Removal
The types of storm water pollutants that accumulate in sediment varies,but may include
contaminants such as heavy metals,petroleum hydrocarbons,and other organic compounds such
as pesticides or so[vents.When the sediment reaches a level of 2",the sediment must be
removed.
S`ediment Disposal
Several methods for disposal are available depending on the concentration of toxins in the waste.
Methods can range from recycling the material,to depositing the sediment into appropriate
landfills.
At the time of disposal, if wastes are deemed to be unfit for disposal in a municipal landfill,a full
' and comprehensive testing program should be run by a qualified person to test for all the
, constiutuents outlined under California code of Regulations(CCR)Title 22. Title 22 list
concentrations of certain chemicals and their soluble threshold limit concentrations(STLC's)and
their total threshold limit concentrations(TTLC's).Chemicals that exceed the allowable
concentrations are considered hazardous wastes and must be removed from the sediment.

Description
Each project site possesses unique topographic,hydrologic,and vegetative features,some of
which are more suitable for development than others. Integrating and incorporating
appropriate landscape planning methodologies into the project design is the most effective
action that can be done to minimize surface and groundwater containination from stormwater.
Approach
Landscape planning should couple consideration of land suitability for urban uses with
consideration of community goals and projected growth. Project plan designs should conserve
natural areas to the e�ent possible,m�imize natural water storage and infiltration
opportunities,and protect slopes and channels.
Suitable Applications
Appropriate applications include residential,commercial and industrial areas plaruied for
development or redevelop�nent.
Design Considerations
Design requirements for site design and landscapes planning
should conform to applicable standards and specifications of
agencies with jurisdiction and be consistent with applicable
General Plan and Local Area Plan policies.

SD-10 Site Design & Landscape Planning
Designing New Instaliations
Begin the development of a plan for the landscape unit with attention to the following general
principles:
■ Formulate the plan on the basis of clearly articulated community goals. Carefully identify
conflicts and choices between retaining and protecting desired resources and community
growth.
■ Map and assess land suitability for urban uses. Include the following landscape features in
the assessment: wooded land,open unwooded land,steep slopes,erosion-prone soils,
foundation suitability,soil suitability for waste disposal,aquifers,aquifer recharge areas,
wetlands,floodglains,surface waters,agricultural lands,and various categories of urban
land use. When appropriate,the assessment can highlight outstanding local or regional
resources that the community determines should be protected(e.g_,a scenic area,
recreational area,threatened species habitat,farmland,fish run). Mapping and assessment
should recognize not only these resources but also additional areas needed for their
sustenance.
Project plan designs should conserve natural areas to the extent possible,ma�umize natural
water storage and infiltration opportunities,and protect slopes and channels_
Conserve Natural Areas during Landscape Planning
If applicable,the following items are required and must be implemented in the site layout
� during the subdivision design and approval process, consistent with applicable General Plan and
Local Area Plan policies:
■ Cluster development on least-seusitive portions of a site while leaving the remaining land in
a natural undisturbed condition.
■ Limit clearing and grading of native vegetation at a site to the minimum amount needed to
build lots,allow access,and provide fire protection.
■ Maxiuuze trees and other vegetation at each site by planting additional vegetation,clustering
tree areas,and promoting the use of native and/or drought tolerant plants.
■ Promote natural vegetation by using parking lot islands and other landscaped areas.
■ Preserve riparian areas and wetlands.
Mc�imize Nat��ral Water Storage and Infzltration Opportunities Within the Landscape Unit
■ Proinote the conservation of forest cover. Building on land that is already deforested affects
basin hydrology to a lesser extent than converting forested land. Loss of forest cover reduces
interception storage,detention in the orgaiuc forest floor layer,and water losses by
evapotranspiration,resulting in large peak runoff increases and either dieir negative effects
or the expense of countering them with structural solutions.
■ Maintain natural storage reservoirs and drainage corridors,including depressions,areas of
permeable soils,swales,and interniittent streams_ Develop and iuiple�ient policies and
`

r
regulations to discourage the clearing,filling,and channelization of these features. Utilize
them in drainage networks in preference to pipes,culverts,and engineered ditches.
■ Evaluating infiltration opportunities by referring to the stormwater management manual for
the jurisdiction and pay particular attention to the selection criteria for avoiding
groundwater contamination,poor soils,and hydrogeological conditions that cause these
facilities to fail. If necessary,locate developments with large amounts of impervious
surfaces or a potential to produce relatively contaminated runoff away froin groundwater
recharge areas_
Protection of Slopes and Channels durfng Landscape Design
■ Convey runoff safely from the tops of slopes.
■ Avoid disturbing steep or unstable slopes.
■ Avoid disturbing natural channels.
■ Stabilize disturbed slopes as quickly as possible.
■ Vegetate slopes with native or drought tolerant vegetation_
■ Control and treat flows in landscaping and/or other controls prior to reaching existing
natural drainage systems.
� ■ Stabilize temporary and permanent channel crossings as quickly as possible,and ensure that
increases in run-off velocity ancl frequency caused by the project do not erode the channel.
■ Install energy dissipaters,such as riprap,at the outlets of new storm drains,culverts,
conduits,or chaxuiels that enter unlined channels in accordance with applicable
specifications to ininimize erosion. Energy dissipaters shall be installed in such a way as to
miniinize impacts to receiving waters.
■ Line on-site conveyance channels where appropriate,to reduce erosion caused by increased
flow velocity due to increases in tributary unpervious area. The first choice for 1'uungs
should be grass or soine other vegetative surface,since these materials not only reduce
runoff velocities,but also provide water quality benefits from filtration and infiltration. If
velocities in the channel are high enough to erode grass or other vegetative linings,riprap,
concrete,soil ceinent,or geo-grid stabilization are other alternatives.
■ Consider other design principles that are comparable and equally effective.
Redeveloping Existing InstaiIaiions
Various jurisdictional stormwater management and nutigation plans(SUSMP,WQMP,etc.)
define"redevelopment"in terms of amounts of additional impervious area,increases in gross
floor area and/or e�rterior construction,and land disturbing activities with structural or
itnpervious surfaces. The definition of"redevelopment"must be consulted to determine
whether or not the require�ients for new development apply to areas intended for
redevelopment. If the definition applies,the steps outlined under"designing new uistallations"
above should be followed_

Redevelopment may present significant opportunity to add features which had not previously
been implemented. Examples include incorporation of depressions,areas of permeable soils,
and swales in newly redeveloped areas_ While some site constraints may exist due to the status
of already e�sting infrasiructure,opportunities should not be missed to maximize infiltration,
slow runoff,reduce impervious areas,disconnect directly connected impervious areas.

Description
Various roof runoff controls are avaiIable to address stormwater
that drains off rooftops. Tlie objective is to reduce the total volume and rate of runoff from
individual lots, and retain the pollutants on site that may be picked up from roofing materials
and atmospheric deposition. Roof runoff controls consist of directing the roof runoff away from
paved areas and mitigafiing flow to the storm drain system through one of several general
� approaches: cisterns or rain barrels;dry wells or infiltration trenches;pop-up einitters,and
� foundation planting. The first three approaches require the roof runoff to be contained in a
gutter and downspout system. Foundation planting provides a vegetated strip under the drip
line of the roof.
Approach
Design of individual lots for single-family homes as well as lots for higher density residential and
commercial structures should consider site design provisions for containing and infiltr�ating roof
runoff or directing roof runoff to vegetative swales or buffer areas. Retained water can be reused
for watering gardens,lawns,and trees. Benefits to the environment include reduced demand for
potable water used for irrigation,improved stormwater quality,iucreased groundwater
recharge,decreased runoff volume and peak flows,and decreased flooding potential.
Suitable Applications
Appropriate applications include residential,commercial and industrial areas planned for
development or redevelopment.
Design Considerations
Designing New Installations
Cisterns or Rain Barrels
One inethod of addressing roof runoff is to direct roof downspouts
to cisterns or rain barrels. A cistern is an above ground storage
vessel with either a manually operated valve ar a permanently
open outlet. Roof runoff is temporarily stored and then released � • �
�
for irrigation or infiltration between stox-�ns. The number of rain

��
barrels needed is a function of the rooftop area. Some low impact developers recommend that
every house have at least 2 rain barrels,with a miniinum storage capacity of i000 liters. Roof
barrels serve several purposes including mitigating the first flush from the roof wluch has a high
volume, amouiit of contaminants,and thermal load_ Several types o€rain barrels are
commercially available. Consideration inust be given to selecting rain barrels that are vector
proof and childproof_ In addition,sonie barrels are designed with a bypass valve that filters out
grit and other contaminants and routes overtlow to a soak-away pit or rain garden.
If the cistern has an operable valve,the valve can be closed to store stormwater for irrigation or
infiltration between storms. This system requires continual monitoring by the resident or
grounds crews,but provides greater flexibility in water storage and metering. If a cistern is
provided with an operable valve and water is stored inside for long periods,the cistern must be
covered to prevent mosquitoes from breeding_
A cistern system with a pei�xnanently open outlet can also provide for metering stormwater
runoff. If the cistern outlet is significantly smaller than the size of the downspout inlet(say i/a to
�/2 inch diameter),runoff will build up inside the cistern during storn�s,and will empty out
slowly after peak intensities subside. This is a feasible way to mitigate the peak flow increases
caused by rooi�op impervious land coverage,especially for the frequent, small storms.
Dry wetls and Inftltration Trenches
Roof downspouts can be directed to dry wells or infiltration trenches. A dry well is coiistructed
by excavating a hole in the ground and filling it with an open graded aggregate,and allowing the
C water to fill the dry well and infiltrate after the storm event_ An undergrouiid connection from
the downspout conveys water into the dry well, allowing it to t�e stored in the voids. To
minimize sedimentation from lateral soil movement,the sides and top of the stone stora,ge
matrix can be wrapped in a permeable filter fabric,though the bottom may remain open. A
perforated observation pipe can be inserted vertically into the dry well to allow for inspection
and maintenance.
In practice,dry wells receiving runoff from single roof downspouts have been successful over
long pei-iods because they contain very little sediment. They must be sized according to the
amount of rooftop runoff received,but are typically 4 to 5 feet square,and 2 to 3 feet deep,with
a minimum of i-foot soil cover over the top(m�imum depth of 10 feet).
To protect the foundation,dry wells must be set away from the building at least io feet. They
must be installed in solids that accommodate infiltration. In poorly drained soils,dry wells have
very limited feasibility.
Infiltration trenches functiou in a similar manner and would be particularly effective for larger
roof areas_ An infiltration trench is a long,narrow,rock-filled trench with no outlet that receives
stormwater runoff. These are desci�ibed under Treatrneirt Controls.
Pop-up Drainage Emitter
Roof downspouts can be directed to an underground pipe that daylights some distance from the
building fouiidation,releasing the roof runoff through a pop-up eniitter_ Similar to a pop-up
iri-igation head,the einitter only opens when there is flow from the roo£ The emitter remains
flush to the ground during dry periods,for ease of lawn or landscape uiaintenance.

Foundation Planting
Landscape planting can be provided around the base to allow increased opportunities for
stormwater infiltration and protect the soil from erosion caused by concentrated sheet flow
coming off the roo£ Foundation plantings can reduce the physical impact of water on the soil
and provide a subsurface inatrix of roots that encourage infiltration. These plantings must be
sturdy enough to tolerate the heavy runoff sheet flows,and periodic soil saturation.
Redevetoping Existing Installations
Vai�ious jurisdictional stormwater management and nutigation plans(SUSMP,WQMP, etc.)
define"redevelopment"in terms of amounts of additional impervious area,increases in gross
floor area and/or exterior construction,and land disturUing activities with structural or
impervious surfaces. The definition of"redevelopment"must be consulted to determine
whether or not the requirements for new development apply to areas intended for
redevelopment_ If the definition applies,the steps outlined under"designing new installations"

Description
Irrigation water provided to landscaped areas may result in excess irrigation water being
conveyed into stormwater drainage systems.
Approach
Project plan designs for development and redevelopment should include application methods of
irrigation water that minimize runoff of excess irrigation water into the storinwater conveyance
C_;
system.
Suitable Applications
Appropriate applications include residential,commercial and industrial areas planned for
development or redevelopment_ (Detached residential single-family homes are typically
excluded from this requirement.)
Design Considerations
Designing New Installations
The following methods to reduce excessive irrigation runoff should be considered,and
incorporated and implemented where determined applicable and feasible by the Permittee:
■ Employ rain-triggered shutoff devices to prevent irrigation after precipitation.
■ Design irrigation systems to each landscape area's specific water requireinents.
■ Include design featuring flow reducers or shutoff valves
triggered by a pressure drop to control water loss in the event
of broken sprinkler heads or lines.
■ Implement landscape plans consistent with County or City
water conservation resolutions,which may include provision
of water sensors,programmable irrigation times(for short
cycles),etc.

■ Design timing and application methods of irrigation water to minimize the runoff of excess
irrigation water into the storm water drainage systein.
■ Group plants with similar water requirements in order to reduce excess irrigation runoff and
promote surface filtration. Choose plants with low irrigation requirements(for example,
native or drought tolerant species). Consider design features such as:
- Using mulches(such as wood chips or bar)in planter areas without ground cover to
minimize sed'unent in runoff
- Installing appropriate plant materials for the location,in accordance with amount of
sunlight and climate,and use native plant materials where possible and/or as
recommended by the landscape architect
- Leaving a vegetative barrier along the property houndary and interior watercourses,to
act as a pollutant filter,where appropriate and feasible
- Choosing plants that minimize or eliuunate tl�e use of fertilizer or pesticides to sustain
growth
■ Einploy other comparable,equally effective methods to reduce irrigation water runoff_

Description Sediment Q
Landscape maintenance activities include vegetation removal; Nutrients Q
herbicide and insecticide application;fertilizer application; Trash Q
watering; and other gardening and lawn care practices. Metals
Vegetation control typically involves a combination of chemical Bacteria
C ' (herbicide)application and mechanical methods. All of these Oil and Grease
maintenance practices have the potential to contribute pollutants Organics
to the storm drain system. The major objectives of this BMP are Oxygen Demanding Q
to minimize the discharge of pesticides,herbicides and fertilizers
to the storm drain system and receiving waters; prevent the
disposal of landscape waste into the storm drain system by
collecting and properly disposing of clippings and cuttings,and
educating employees and the public.
Approach
Pollution Prevenfion
■ Implement an integrated pest management(IPM) program.
IPM is a sustainable approach to managing pests by
combining biological, cultural,physical,and chemical tools.
■ Choose low water using flowers,trees,shrubs,and
groundcover.
■ Consider alternative landscaping techniques such as
naturescaping and xeriscaping.
■ Conduct appropriate maintenance(i.e.properly timed
fertilizing,weeding, pest control,and pruning)to help
preserve the landscapes water efficiency. � � �

��
■ Consider grass cycling(grass cycling is the natural recycling of grass by leaving the clippings
on the lawn when mowing. Grass clippings decompose quickly and release valuable
nutrients back into the lawn).
Suggested Frotocols
Mowing, Trimming,and Weeding
■ Whenever possible use mechanical methods of vegetation removal(e.g mowing with tractor-
type or push mowers,hand cutting with gas or electric powered weed trimmers)rather than
applying herbicides. Use hand weeding where practical.
■ Avoid loosening the soil when conducting mechanical or manual weed control,this could
lead to erosion. Use mulch or other erosion control measures when soils are exposed.
■ Performing mowing at optimal times. Mowing should not be performed if significant rain
events are predicted.
■ Mulching mowers may be recommended for certain flat areas. Other techniques may be
einployed to minimize mowing such as selective vegetative planting using low maintenance
grasses and shrubs.
■ Collect lawn and garden clippings,pruning waste,tree trimmings,and weeds. Chip if
necessary,and compost or dispose of at a landfill(see waste management section of this fact
sheet).
` ■ Place temporarily stockpiled material away from watercourses,and berm or cover stockpiles
to prevent material releases to storm drains.
Planting
■ Determine existing native vegetation features(location,species,size,function,importance)
and consider the feasibility of protecting them. Consider elements such as their effect on
drainage and erosion,hardiness,maintenance requirements,and possible conflicts between
preserving vegetation and the resulting maintenance needs.
■ Retain and/or plant selected native vegetation whose features are determined to be
beneficial,where feasible. Native vegetation usually requires less maintenance(e.g.,
irrigation,fertilizer)than planting new vegetation.
■ Consider using low water use groundcovers when planting or replanting.

■ Compost leaves,sticks,or other collected vegetation or dispose of at a permitted landfill. Do
not dispose of collected vegetation into waterways or storm drainage systems.
■ Place temporarily stockpiled material away from watercourses and storm drain inlets,and
berm or cover stockpiles to prevent material releases to the storm drain system.
■ Reduce the use of high nitrogen fertilizers that produce excess growth requiring more
frequent mowing or trimming.

■ Avoid landscape wastes in and around storm drain inlets by either using bagging equipment
or by manually picking up the material.
Irrigation
■ Where practical,use automatic timers to minimize runoff.
■ Use popup sprinkler heads in areas with a lot of activity or where there is a chance the pipes
may be broken. Consider the use of inechanisms that reduce water flow to sprinkler heads if
broken.
■ Ensure that there is no runoff from the landscaped area(s)if re-claimed water is used for
irrigation.
■ If bailing of muddy water is required(e.g.when repairing a water line leak),do not put it in
the storm drain;pour over landscaped areas.
■ Irrigate slowly or pulse irrigate to prevent runoff and then only irrigate as much as,is
needed.
■ Apply water at rates that do not exceed the infiltration rate of the soil.
Fertilizer and Pesticide Management
■ Utilize a comprehensive management system that incorporates integrated pest management
(IPM)techniques. There are many methods and types of IPM,including the following:
C - Mulching can be used to prevent weeds where turf is absent,fencing installed to keep
rodents out,and netting used to keep birds and insects away from leaves and fruit.
- Visible insects can be removed by hand(with gloves or tweezers)and placed in soapy
water or vegetable oil. Alternatively,insects can be sprayed off the plant with water or in
some cases vacuumed off of larger plants.
- Store-bought traps,such as species-specific,pheromone-based traps or colored sticky
cards, can be used.
- Slugs can be trapped in small cups filled with beer that are set in the ground so the slugs
can get in easily.
- In cases where microscopic parasites,such as bacteria and fungi,are causing damage to
plants,the affected plant material can be removed and disposed of(pruning equipment
should be disinfected with bleach to prevent spreading the disease organism).
- Small mammals and birds can be excluded using fences,netting,tree trunk guards.
- Beneficial organisms,such as bats,birds,green lacewings,ladybugs,praying mantis,
ground beetles,parasitic nematodes,trichogramma wasps,seed head weevils,and
spiders that prey on detrimental pest species can be promoted.
■ Follow all federal,state, and local laws and regulations governing the use,storage,and
disposal of fertilizers and pesticides and training of applicators and pest control advisors.

SC-73 Landscape Maintenance
■ Use pesticides only if there is an actual pest problem(not on a regular preventative
schedule).
■ Do not use pesticides if rain is expected. Apply pesticides only when wind speeds are low
(less than 5 mph).
■ Do not mix or prepare pesticides for application near storm drains.
■ Prepare the minimum amount of pesticide needed for the job and use the lowest rate that
will effectively control the pest.
■ Employ techniques to minimize off-target application(e.g.spray drift)of pesticides,
including consideration of alternative application techniques.
■ Fertilizers should be worked into the soil rather than dumped or broadcast onto the surface.
■ Calibrate fertilizer and pesticide application equipment to avoid excessive application.
■ Periodically test soils for determining proper fertilizer use.
■ Sweep pavement and sidewalk if fertilizer is spilled on these surfaces before applying
irrigation water.
■ Purchase only the amount of pesticide that you can reasonably use in a given time period
C (month or year depending on the product).
■ Triple rinse containers,and use rinse water as product. Dispose of unused pesticide as
hazardous waste.
■ Dispose of empty pesticide containers according to the instructions on the container label.
Inspection
■ Inspect irrigation system periodically to ensure that the right amount of water is being
applied and that excessive runoff is not occurring. Minimize excess watering,and repair
leaks in the irrigation system as soon as they are observed. �
■ Inspect pesticide/fertilizer equipment and transportation vehicles daily.
Training
■ Educate and train employees on use of pesticides and in pesticide application techniques to
prevent pollution. Pesticide application must be under the supervision of a California
qualified pesticide applicator.
■ Train/encourage municipal maintenance crews to use IPM techniques for managing public
green areas.
■ Annually train employees within departments responsible for pesticide application on the
appropriate portions of the agenc�s IPM Policy,SOPs,and BMPs, and the latest IPM
techniques.

�-
■ Employees who are not authorized and trained to apply pesticides should be periodically(at
least annually) informed that they cannot use over-the-counter pesticides in or around the
workplace.
■ Use a training log or similar method to document training.
Spill Response and Prevention
■ Refer to SC-i1, Spill Prevention, Control&Cleanup
■ Have spill cleanup materials readily available and in a know in location
■ Cleanup spills immediately and use dry methods if possible.
■ Properly dispose of spill cleanup material.
Other Considerations
■ The Federal Pesticide, Fungicide, and Rodenticide Act and California Title 3, Division 6,
Pesticides and Pest Control Operations place strict controls over pesticide application and
handling and specify training,annual refresher,and testing requirements. The regulations
generally cover:a list of approved pesticides and selected uses,updated regularly; general
application information; equipment use and maintenance procedures; and record keeping.
The California Department of Pesticide Regulations and the County Agricultural
Commission coordinate and maintain the licensing and certification programs. All public
agency employees who apply pesticides and herbicides in"agricultural use"areas such as
� parks,golf courses,rights-of-way and recreation areas should be properly certified in
accordance with state regulations. Contracts for landscape maintenance should include
similar requirements.
■ All employees who handle pesticides should be familiar with the most recent material safety
data sheet(MSDS)files.
■ Municipalities do not have the authority to regulate the use of pesticides by school districts,
however the California Healthy Schools Act of 2000 (AB 2260)has imposed requirements
on California school districts regarding pesticide use in schools. Posting of notification prior
to the application of pesticides is now required,and IPM is stated as the preferred approach
to pest management in schools.
Requirements
Costs
Additional training of municipal employees will be required to address IPM techniques and
SMPs. IPM methods will likely increase labor cost for pest control which may be offset by lower
chemical costs.

Supplemental Information
Further Detail of the BMP
Waste Management
Composting is one of the better disposal alternatives if locally available. Most municipalities
either have or are planning yard waste composting facilities as a means of reducing the amount
of waste going to the landfill. Lawn clippings from municipal maintenance programs as well as
private sources would probably be compatible with most composting facilities
Contractors and Other Pesiicide Users
Municipal agencies should develop and implement a process to ensure that any contractor
employed to conduct pest control and pesticide application on municipal property engages in
pest control methods consistent with the IPM Policy adopted by the agency. Specifically,
municipalities should require contractors to follow the agency's IPM policy, SOPs,and BMPs;
provide evidence to the agency of having received training on current IPM techniques when
feasible; provide documentation of pesticide use on agency property to the agency in a timely
manner.

design as developed by the National Crime Prevention Institute (NCPI) supports the concept
that"the proper design and effective use of the built environment can lead to a reduction in the
fear and incidence of crime and an improvement in the quality of life." The nine primary
strategies that support this concept are included as conditions below:
a. Provide clear border definition of controlled space. Examples of border definition may
include fences, shrubbery or signs in exterior areas. Within a building, the arrangement of
furniture and color definition can serve as a means of identifying controlled space.
b. Provide clearly marked transitional zones. Persons need to be able to identify when they
are moving from public to semi-public to private space.
c. Gathering or congregating areas to be located or designated in locations where there is good
surveillance and access control.
d. Place safe activities in unsafe locations. Safe activities attract normal users to a location
and subsequently render the location less attractive to abnormal users due to observation
( and possible intervention.
� e. Place unsafe activities in safe locations. Placing unsafe activities in areas of natural
surveillance or controlled access will help overcome risk and make the users of the areas
feel safer.
f. Redesign the use of space to provide natural barriers. Separate activities that may conflict
with each other(outdoor basketball court and children's play area, for example) by distance,
natural terrain or other functions to avoid such conflict.
g. Improve scheduling of space. The timing in the use of space can reduce the risk for normal
users and cause abnormal users to be of greater risk of surveillance and intervention.
h. Redesign space to increase the perception of natural surveillance. Abnormal users need to
be award of the risk of detection and possible intervention. Windows and clear lines-of-sight
serve to provide such a perception of surveillance.
i. Overcome distance and isolation. This strategy may be accomplished through improved
communications (portable finro-way radios, for example) and design efficiencies, such as the
location of restrooms in a public building.
139. Business Security Surve�r. Businesses desiring a business security survey of their location
can contact the Crime Prevention and Plans Unit of the Temecula Police Department at (951)
695-2773.
140. Questions Reqarding Conditions. Any questions regarding these conditions should be
directed to the Temecula Police Department Crime Prevention and Plans Unit at (951)
695-2773.

A. Purpose
The purpose of this manual is to provide maintenance instructions for the infiltration trench
located northwest side of the building. The infiltration trench treats urban runoff before it enters
into the onsite storm drain system. Maintenance per this manual will ensure the infiltration
trenches function as designed.
This manual will serve as a reference guide to assist the property owner with the following:
1. Overview of the infiltration trench and planter box and how they function
2. Description of the location of the infiltration trench and planter box
3. Procedure required to effectively maintain the infiltration trench and planter box
4. Reproducible copies of the forms, logs, and guidelines necessary for recording
maintenance activities associated with the infiltration trench.
B. General Description and Function of the Infiltration Trench and Planter Box
Infiltration Trench
The infiltration trench is a 177'by 20' basin that is 1' deep on the surface and 3' deep under the
surface that allows urban runoff to infiltrate into the ground. From the top of the trench to the
� bottom the material consists of:
C-� 1. Mulch or landscape material on top
2. 1' of pea gravel
3. 2' of washed rock(1" to 3" diameter)
4. Impermeable liner on the sides of the trench

The basin contains an overflow outlet with an 8" pvc pipe that connects to an 18" pipe from the
Temecula Medial Office Building project. The 18" pipe ties into an existing storm drain in
Margarita Road.
Runoff is treated by passing through the pea gravel and rock within the trench and ultimately
through infiltration into the ground under the trench.
Planter Box
The planter box is 10' x 160' x 0.5' deep with an outlet that is 4" off the bottom of the planter.
The outlet pipe is 6" pvc and ties into the infiltration trench. See diagram below:

C. Maintenance Responsibility
The property owner, TV Phase One, LLC is responsible for maintaining the infiltration trench
and planter box. The goal of maintenance is to ensure that infiltration is occurring. Regular
inspection and replacement of materials within the trench and planter box once they become
ineffective in performing as designed are the major components in the maintenance program.
Trash, litter, and debris will also need to be removed on a regular basis. The following general
procedures should be followed:
1. Qualified maintenance personnel should periodically inspect the trench and planter box
every 6 months.
2. If a problem is identified, it should be resolved as soon as possible to ensure that the
trench and planter box function as designed.
3. Regular removal of trash and debris should occur. Any visible trash or debris should be
promptly removed.
Detailed maintenance procedures are outlined in Section E
D. Maintenance Indicators and Activities
Functional Maintenance
Regular functional maintenance is required to ensure that the infiltration trench and planter box
� ', perform in an effective manner. Functional maintenance consists of both preventative and
- corrective activities. Logs and guide sheets are contained herein to use in recording vital
information while performing operation inspection and other infiltration trench and planter box
maintenance activities. Maintenance records shall be kept by the property owner for a minimum
of 5 years. The proper use and subsequent storage of these records will assure the City of
Temecula that the infiltration trench and planter box are functioning as designed.
Preventative Maintenance
Preventative maintenance shall be performed on a regular basis. Checklists are included herein
to track and record preventative maintenance activities. These activities include trash and debris
removal and sediment management.
Trash and debris removal shall be performed to ensure that runoff has adequate surface axea to
infiltrate through the vaxious layers that comprise the cross section of the trench and to ensure the
planter box functions properly.
Sediment management will occur when testing indicates that the infiltration rate has diminished
below the stated acceptable rate.
Corrective Maintenance
Corrective maintenance will be required on an emergency or non-routine basis to correct
problems and restore intended operation and safe function of the infiltration trench and planter
'��, box.

Infiltration Trench Maintenance .
1. Inspect minimum of twice per year, before and after the rainy season, after large storms or
more frequently as needed.
2. Clean the trench when the loss of infiltration capacity is observed. When standing water
is present for a period of time in excess of 72 hours, removal of sediment may be
necessary. This is an expensive activity and the need for it may be minimized through the
prevention of erosion.
3. Control mosquitoes as necessary
4. Remove litter and debris from surface as required
PlanteN Box Maintenance
1. Inspect minimum of twice per year, before and after the rainy season, after large storms or
more frequently as needed.
2. Clean the planter box when the loss of function is observed. When standing water is

Maintenance Indicators
Maintenance indicators are signs that indicate that maintenance personnel need to check the
infiltration trench and planter box for maintenance needs. The most common trigger include
warnings or accounts of standing water and sediment accumulation. The proceeding Table 1
show conditions and criteria that trigger the need for some specific routine infiltration trench and
;�
4/8
��, planter box maintenance activities. Emergencies that occasionally arise would require a more
' urgent, critical response.
Sediment Removal
The types of storm water pollutants that accumulate in sediment varies,but may include
contaminants such as heavy metals, petroleum hydrocaxbons, and other organic compounds such
as pesticides or solvents. When the sediment reaches a level of 2",the sediment must be
removed.
Sediment Disposal
Several methods for disposal are available depending on the concentration of toxins in the waste.
Methods can range from recycling the material,to depositing the sediment into appropriate
landfills.
At the time of disposal, if wastes are deemed to be unfit for disposal in a municipal landfill, a full
and comprehensive testing program should be run by a qualified person to test for all the
constiutuents outlined under California code of Regulations (CCR) Title 22. Title 221ist
concentrations of certain chemicals and their soluble threshold limit concentrations (STLC's) and
