Water Quality Management Plan (WQMP)
Butte�eld Stage Road Imp
� III. Pollutants of Concern
Potential pollutants associated with Urban Runoff from the proposed project must be identified. Exhibit B of the
WQMP provides brief descriptions of typical pollutants associated with lJrban Runoff and a table that
associates typical potential pollutants with types of development (land use). It should be noted that at the Co-
Permittees discretion, the Co-Permittees may also accept updated studies from the California Association of
Stormwater Quality Agencies (CASQA), USEPA, SWRCB and/or other commonly accepted
agencies/associations acceptable to the Co-Permittee for determination of Pollutants of Concern associated with
given land use. Additionally, in identifying Pollutants of Concern, the presence of ]egacy pesticides, n�trients,
or hazardous substances in the site s soils as a result of past uses and their potential for exposure to Urban
Runoff must be addressed in project-specific WQMPs. The Co-Permittee may also require specific pollutants
commonly associated with urban runoff to be addressed based on known problems in the watershed. The ]ist of
potential Urban Runoff pollutants identified for the project must be compared with the pollufants identified as
causing an impairment of Receiving Waters, if any. To identify pollutants impairi�g proximate Receiving
Waters, each project proponent preparing a project-specific WQMP shall, at a minimum, do Che following:
l. For each of the proposed project discharge points, identify the pro�imate Receiving Water for each
discharge point, using hydrologic unit basin numbers as identified in the mosf recent version of the
Water Quality Control Plan for the Santa Ana River Basin or the San Diego Region.
2. Identify each proximate identified above that is listed on the most recent list of Clean Water Act
Section 303(d) ]ist of impaired water bodies, which can be found at website
wwwswreb.ca.gov/tmdl/303d_Iists.htmL List all pollutants for which the proximate Receiving Waters
• are impaired.
3. "Street, Roads, Highways, and Freeways" will be used as the pollutant category for this WQMP. As
sucl�, the pollutants associated with this category are ]isted below.

Greg,
Thank you, the reaponses below have.satisfied our concerns. The��CiEy may proceed with Ehe
public���infrastructure�improvements desciibed in you'r 7/28J08 email.
When the improvements are completed, please submit a letter to the Regional Board
documenting the work that was completed, including all of the BMPS that were install.ed or
improved as well as any culverts that were installed such as the one in the vicinity of La
Serena.
feel free to contact me with any questions,

Mariah,
The culvert is comprised of a 60" diameter reinforced concrete pipe, the
"bottom�� of the culvart will be the interior of the pipe so it will be
conerete.
The culvert design/installation includes headwalls and aprons at the
inlet and outlet control points to eliminate adverse impacts. The
outlet will also incorporate an energy dissipater to slow the flow down
to pre-construction condition� thereby eliminating any erosion concern.
Pipe capacity is 368 cubic feet per second (cfs). A 100-year design
storm even.t would produce a maximum flow of 235 cfs so there will be no
backwater effect at the entrance.

Greg,
You note below that the EIR analyzed the impacts from the offsite
improvements. Does the EIR recognize a drainage at the crossing at La
Serena? If it does, what type of mitigation is provided for the fill of
this area? We require more than just conservation of existing
resources, mitigation m�st be provided in the form of creation or
restoration of waters.
thanks,
Mariah

Jeff, Jim & Mariah:
�
As was discussed during our recent telephone conversations, meetings, 1
and site visits, the City of Temecula (City) is pursuing the �
construction of a few of the public infrastructure improvements ;
conditioned .upon the Roripaugh Ranch Development. Specifically the City
will be contracting for: i
* Completion of Murrieta Hot Springs Road (currently base paved) �
* Construction Butterfield Stage Road from Murrieta Hot Springs �
Road south to La Serena Road. (currently onsite rough grading is
complete, no offsite work has started) �
* Construction Calle Chapos between Walcott and Butterfield Stage
Road and the Soueh Loop Road (extension of Calle Chapos) easterly along �
the frontage of the existing unoccupied fire station. (currently onsite
rough grading is complete) �
* Construction of Nicolas Road within the development may also be �
completed (currently rough grading is complete), if adequate funding is �
available �
�
The construction will i.nclude roadwa mass radin �
y g g (offsite), £inish
grading (onsite), paving, curb and gutter, sidewalk, street lights,
storm drain s stems with � �
y post construction BMP s, medians, and signing �
and striping. Note that a majority of the work will build upon $
developer, Ashby USA, completed mass grading and crossings over Santa �
Gertrudis Creek and Long Valley Wash.
The attached exhibit titled "Proposed City Constructed Public
Improvements (ROripaugh Ranch CFD) shows the limits of the proposed City
improvements. In addition, the attached photographs taken on Tuesday,
July 22, 2008, show existing conditions.

In terms of ownerships within the Panhandle area (Tract 29661), per our GIS records and to the best of our knowledge,
the individual owners involved in this area are as follows: phase 1- Wingsweep Corp; Phase 2— BHT Roripaugh WB99;
Phase 3 and 4— HRA Roripaugh 1& 2; final phase —Sunwood Roripaugh Ranch. Regarding Ashby USA LLC's interest, the •
latest title report dated 9/23/10 on this property shows 2 entities in which title is vested....Temecula Land Partners I, LLC
and Temecula Land Partners II, LLC .
As you can see, this property's change of ownerships and notes have become convoluted and complicated. However, as
it relates to the City project, the City is almost complete with the bid package for Phase I and expects to go out to bid by
the end of the year. We have obtained the regulatory agencies' clearances on the construction of BSR and understand
that Ashby USA, LLC or a future developer is still obligated to mitigate, as previously conditioned and/or spelied out in
the existing permits. The City will work with the regulatory agencies to ensure that this occurs, as conditioned.
Please note that Pete Olah is not a representative of the City or our City project. He has been retained by a developer,
who has been negotiating and/or is interested in developing the "Pan" area of Roripaugh Ranch Development. As I
understand it, his il/16 meeting with the RB is on behalf of his employer, in hopes to determine what their
outstanding obligations and mitigations are for their project.
Please review this information, as necessary. If you need additional info, let me know. I hope this relieves you of your
initial concerns over our City project. However, we can certainly make ourselves available for a conference call and/or
meeting here at City Hall. Let me know what works for you. Thanks Chiare.
