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 Iocations 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. 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 compliance. Did you identify and preserve existing drainage patterns? if so, how? If not, why? No natural drainage patterns exist on the project site as the entire site has been previously disturbed and made into a mass graded pad. The project will maintain the existing discharge point to Single Oak Drive. Did you identify and protect existing vegetation? If so, how? If not, why? The entire site has been previously disturbed. The only vegetation that exists on the site is several trees along a cut slope and sparse weeds and seasonal grasses on the pad. Di you identify and preserve natural infiltration capacity? If so, how? If not, why? The infiltration capacity of the site will be affected by the addition of impervious surfaces to the site. This will be partially mitigated by the use of permeable paving areas. Did you identify and minimize impervious area? If so, how? If not, why? All impervious areas have been identified on the WQMP site plan included with this report. Impervious areas such as drive aisles and parking stalls have been designed to occupy the smallest foot print while still meeting the intent of the design. Permeable paving is also proposed for certain portions of the site. Did you identify and disperse runoff to adjacent pervious areas? If so, how? If not, why? Runoff from impervious areas will be directed to one of two bioretention areas t� �J Water Quality Management Plan [WQMP] Home2 Suites Section C: Delineate Drainage Management Areas (DMAs) Utilizing the procedure in Section 3.3 of the WQMP Guidance Document which discusses the methods of delineating and mapping your project site into individual DMAs, complete Table CA below to appropriately categorize the types of classification (e.g., Type A, Type B, etc.) per DMA for your Project site. Upon completion of this table, this information will then be used to populate and tabulate the corresponding tables for their respective DMA classifications.

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? ❑ 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. Table D.1 Infiltration Feasibility Does the project site... YES No ...have any DMAs with a seasonal high groundwater mark shallower than 10 feet?

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: 1.14 a Type of Landscaping (Conservation Design or Active 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: 0.37 acres (building roof) 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: 2.92 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: 4.46 acres Step 5: Determine if harvesting stormwater runoff for irrigation use is feasible for the project by comparing the total area of irrigated landscape (Step 1) to the minimum required irrigated area (Step 4).

Applicant Public or private entity seeking the discretionary approval of new or replaced improvements from the Copermittee with jurisdiction over the project site. The Applicant has overall responsibility for the implementation and the approval of a Priority Development Project. The WQMP uses consistently the term "user" to refer to the applicant such as developer or project proponent. The WQMP employs also the designation "user" to identify the Registered Professional Civil Engineer responsible for submitting the Project -Specific WQMP, and designing the required BMPs. Best Management Defined inn 40 CFR 122.2 as schedules of activities, prolvbitions of Practice (BMP) practices, maintenance procedures, and other management practices to prevent or reduce the pollution of waters of the United States. BMPs also include treatment requirements, operating procedures and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage. In the case of municipal storm water permits, BMPs are typically used in place of numeric effluent limits. BMP Fact Sheets BMP Fact Sheets are available in the LID BMP Design Handbook. Individual BMP Fact Sheets include sitting considerations, and design and sizing guidelines for seven types of structural BMPs (infiltration basil, infiltration trench, permeable pavement, harvest - and -use, bioretention, extended detention basin, and sand filter). California Publisher of the California Stormwater Best Management Practices Stormwater Quality Handbooks, available at Association (CASQA) www.cabml2handbooks.com. Conventional A type of BMP that provides treatment of stormwater runoff. Treatment Control Conventional treatment 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 Treatment BMPs can be considered or implemented. Copermittees The 2010 SMR MS4 Permit identifies the Cities of Murrieta, Temecula, and Wildomar, the County, and the District, as Co ermittees for the SMR. County The abbreviation refers to the County of Riverside in this document. CEQA California Environmental Quality Act -- a statute that requires state and local agencies to identify the significant environmental impacts of their actions and to avoid or mitigate those impacts, if feasible. - 34 - 01 Water Quality Management Plan (WQMP) HQme2 Suites CIMIS California Irrigation Management Information System - an integrated network of 118 automated active weather stations all over California managed by the California Department of Water Resources. CWA Clean Water Act - is the primary federal law governing water pollution. Passed in 1972, the CWA established the goals of eliminating releases of high amounts of toxic substances into water, eliminating additional water pollution by 1985, and ensuring that surface waters would meet standards necessary for human sports and recreation by 1983. CWA Section 402(p) is the federal statute requiring NPDES permits for dischar es from MS4s. CWA Section 3O3(d) Impaired water in which water quality does not meet applicable Waterbody water quality standards and/or is not expected to meet water quality standards, even after the application of technology based pollution controls required by the CWA. The discharge of urban runoff to these water bodies by the Copermittees is significant because these discharges can cause or contribute to violations of applicable water uali standards. Design Storm The 2010 SMR MS4 Permit has established the 85th percentile, 24- hour storm event as the "Design Storm". The applicant may refer to Exhibit A to identify the applicable Design Storm Depth (D85) to the project. DCV Design Capture Volume (DCV) is the volume of runoff produced from the Design Storm to be mitigated through LID Retention BMPs, Other LID BMPs and Volume Based Conventional Treatment BMPs, as appropriate. Design Flow Rate The design flow rate represents the minimum flow rate capacity that flow -based conventional treatment control BMPs should treat to the MEP, when considered. DCIA Directly Connected Impervious Areas - those impervious areas that are hydraulically connected to the MS4 (i.e. street curbs, catch basins, storm drains, etc.) and thence to the structural BMP without flowing over pervious areas. Discretionary A decision un which a Copermittee uses its judgment in deciding Approval whether and how to carry out or approve a project. District Riverside County Flood Control and Water Conservation District. DMA A Drainage Management Area - a delineated portion of a project site that is hydraulically connected to a common structural BMP or conveyance point. The Applicant may refer to Section 3.3 for further guidelines on how to delineate DMAs. -35- (l Water Quality Management Plan (WQMP) Home2 Suites Drawdown Time Refers to the amount of time the design volume takes to pass through the BMP. The specified or incorporated drawdown times are to ensure that adequate contact or detention time has occurred for treatment, while not creating vector or other nuisance issues. It is important to abide by the drawdown time requirements stated in the fact sheet for each specific BMP. Effective Area Area which 1) is suitable for a BMP (for example, if infiltration is potentially feasible for the site based on infeasibility criteria, infiltration must be allowed over this area) and 2) receives runoff from impervious areas. ESA An Environmental Sensitive Area (ESA) designates an area "in wluch plants or animals life or their habitats are either rare or especially valuable because of their special nature or role in an ecosystem and which would be easily disturbed or degraded by human activities and developments". (Reference: California Public Resources Code § 30107.5). ET Evapotranspiration (ET) is the loss of water to the atmosphere by the combined processes of evaporation (from soil and plant surfaces) and transpiration (from plant tissues). It is also an indicator of how much water crops, lawn, garden, and trees need for healthy growth and productivity FAR The Floor Area Ratio (FAR) is the total square feet of a building divided by the totalsquare feet of the lot the building is located on. Flow -Based BMP Flow -based BMPs are conventional treatment control BMPs that are sized to treat the design flow rate. F p p p Facility Pollution Prevention Plan HCCC Hydrologic Condition of Concern - Exists when the alteration of a site's hydrologic regime caused by development would cause significant impacts on downstream channels and aquatic habitats, alone or in conjunction with impacts of other projects. HMP Hydromodification Management Plan - Plan defining Performance Standards for PDPs to manage increases in runoff discharge rates and durations. Hydrologic Control BMP to mitigate the increases u1 runoff discharge rates and BMp durations and meet the Performance Standards set forth in the HMP. HSG Hydrologic Soil Groups - soil classification to indicate the minimum rate of infiltration obtained for bare soil after prolonged wetting. The HSGs are A (very low runoff potential/ high infiltration rate), B, C, and D (high runoff potential/very low infiltration rate) Hydromodification The 2010 SMR MS4 Permit identifies that increased volume, velocity, frequency and discharge duration of storm water runoff from developed areas has the potential to greatly accelerate downstream erosion, impair stream habitat u1 natural drainages, and negatively impact beneficial uses. -36- �1 Water Quality Management Plan (WQMP) Home2 Suites JRMP A separate Jurisdictional Runoff Management Plan (JRMP) has been developed by each Copermittee and identifies the local programs and activities that the Copermittee is implementing to meet the 2010 SMR MS4 Permit requirements. LID Low Impact Development (LID) is a site design strategy with a goal of maintaining or replicating the pre --development hydrologic regime through the use of design techniques. LID site design BMPs help preserve and restore the natural hydrologic cycle of the site, allowing for filtration and infiltration which can greatly reduce the volume, peak flow rate, velocity, and pollutant loads of storm water runoff. LID BMP A type of stormwater BMP that is based upon Low Impact Development concepts. LID BMPs not only provide highly effective treatment of stormwater runoff, but also yield potentially significant reductions hi runoff volume - helping to mimic the pre - project hydrologic regime, and also require less ongoing maintenance than Treatment Control BMPs. The applicant may refer to Chapter 2. LID BMP Design The LID BMP Design Handbook was developed by the Handbook Copermittees to provide guidance for the planning, design and maintenance of LID BMPs which may be used to mitigate the water quality impacts of PDPs within the Coun . 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 promote 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 BMp 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 underdraun. LID Harvest and BMPs used to facilitate capturing Stormwater Runoff for later use Reuse BMP without negatively impacting downstream water rights or other Beneficial Uses. -37- Water Quality Management Plan (WQMP) Home2 Suites LID Infiltration BMP BMPs to reduce stormwater runoff by capturing and infiltrating the runoff into in -situ soils or amended onsite soils. Typical LID Infiltration BMPs include infiltration basins, infiltration trenches and pmvious pavements. LID Retention BMP BMPs to ensure full onsite retention without runoff of the DCV such as infiltration basins, bioretention, chambers, trenches, permeable pavement and pavers, harvest and reuse. LID Principles Site design concepts that prevent or minimize the causes (or drivers) of post -construction impacts, and help mimic the pre - development hydrologic regime. MEP Maximum Extent Practicable - standard established by the 1987 amendments to the CWA for the reduction of Pollutant discharges from MS4s. Refer to Attachment C of the 2010 SMR MS4 Permit for a complete definition of MEP. MF Multi -family - zoning classification for parcels having 2 or more living residential units.
