Under existing conditions, runoff generally sheet flows north and east to the eastern corner of the site where it is intercepted by an existing pump station located on the South Orange County Wastewater Authority (SOCWA) property. Drainage Runoff ultimately discharges to San Juan Creek immediately east of the pump Patterns/Connections house. Under proposed conditions, new storm drains will be constructed on-site to convey runoff to the existing pump house and outlet to San Juan Creek. The project site does not receive runon from off-site areas. The proposed VTTM 17146 project site encompasses approximately 9 acres located on the eastern corner of Pacific Coast Highway and Del Obispo Street in the City of Dana Point (see attached Vicinity Map). Historically, the project site was a mobile home park. All mobile homes have since been removed, and the site is currently vacant with some vegetation and remnant paved drive aisles. The Project includes the removal of the remnant paved areas for the construction of 169 condominium units, a portion of which will be affordable Narrative Project residential units. New drive aisles, surface parking and utility improvements are Description: also proposed. On-site landscaping will consist of areas along sidewalks, adjacent to buildings, drive aisles, parking spaces, and around the perimeter of the site. In addition, two “visitor serving use” areas will be located along Pacific Coast Highway, and include open space/landscaped areas for public use. Parking will be located on-site as surface spaces and within garages. A total of 456 spaces will be provided, 368 of which are garage spaces and 88 are open spaces.

HYDROLOGIC CONDITIONS OF CONCERN (HCOCS)
Per the approved South Orange County Hydromodification Management (HMP) dated October 25, 2012 (with the revisions included in the July 31, 2013 approval letter by the San Diego Regional board), there are two ways a project in this location can be considered exempt from Hydromodification requirements. 1. Priority Development Projects discharging storm water runoff directly into underground storm drains that discharge directly to bays or the ocean; 2. Priority Development Projects discharging runoff into conveyance channels whose bed and bank are concrete lined all the way from the point of discharge to ocean waters, enclosed bays, estuaries or water storage reservoirs. This project is exempt from hydromodification requirements because it drains directly into ocean waters at the point of discharge. Please refer to the documentation in Attachment F. The limit of the ocean fluctuates at any given time depending on tidal elevation, rain events, beach sand replenishment and erosion. When designing for on-site drainage facilities discharging to the ocean, standard hydraulic controls include Mean Higher High Water (MHHW) elevation and the impacts of backwater and wave action. The resulting elevation varies per jurisdiction but typically it is within the 10’ to 11’ range. The channel bottom/ocean bottom adjacent to the VTTM 17146 project site is approximately 8’ currently and was lower previously as there is evidence of aggradation within this area as represented in the Army Corps study on San Juan Creek (San Juan Creek Watershed Management Study, Orange County CA published August 2002 by US Army Corps of Engineers Los Angeles District). This study identified that the area adjacent the project has been undergoing aggradation of sediment form 1984 to 1998 (limits of study duration for 2002 report). Based on these facts, our project drains to the Ocean and is considered exempt from Hydromodification requirements. Supporting documentation is provided in Attachment F.
II.4II.4II.4 PostPostPost- Post---DevelopmentDevelopment Drainage Characteristics Under proposed conditions, the storm drains will be constructed on-site to convey runoff ultimately discharge to the existing pump house and outlet to San Juan Creek. Although the project is exempt from the hydromodification requirements, detention will be required on-site to maintain peak flows to the pump station at or below the design flow assigned to the project area in the pump design calculations, as well as to detain flows prior to discharging into the proposed biotreatment systems. The detention system, as part of the storm drain system, will be placed in the drive aisles within the project near the downstream biofiltration BMPs. Further details on the proposed biofiltration system are provided in Section IV.3.4.

SITE CHARACTERISTICS
Under proposed conditions, new storm drains will be constructed on-site to convey runoff to the existing pump house and outlet to San Juan Creek. A copy of the agreement/Memorandum of Understanding with SOCWA is included as Attachment H. The project site does not receive runon from off-site areas. Proposed Drainage Detention will be required to maintain peak flows to the pump station at or below Patterns/Connections the design flow assigned to the project area in the pump design calculations. Also, due to the use of flow through design biofiltration BMPs (Modular Wetlands), storage of at least 75% of the Design Capture Volume is required for water quality treatment. The detention system, as part of the storm drain system, will be placed in the drive aisles within the project near the downstream biofiltration BMPs. Soils on the project site consist of alluvium with minor amounts of artificial fill. The Soil Type, Geology, and native alluvium typically consists of sands with some silts and gravels, and are Infiltration Properties generally moist and medium dense with interbedded loose zones and dense zones.1 Previous geotechnical investigations adjacent to the site noted groundwater at Hydrogeologic depths ranging from 5 ft to 11 ft below ground surface (bgs). During the on-site (Groundwater) Conditions geotechnical study, groundwater was encountered at 7.25 ft to 11 ft bgs. Historic high groundwater is estimated at 5 ft bgs.2 The project site is located in an area with shallow groundwater (5-10 ft below ground surface). In addition, the geotechnical investigation identified the Geotechnical Conditions liquefaction potential at the site is expected to be high. Due to the geotechnical (relevant to infiltration) concerns of the site, in addition to the presence of shallow groundwater, infiltration of storm water runoff is considered infeasible. Further details are provided in Section IV.3.2 and Attachment G. Off-Site Drainage None. The project site is located adjacent to the San Juan Creek channel and the South Utility and Infrastructure Orange County Wastewater Authority. There are existing easements on-site for Information various utility purposes (gas, electric, sewer and other utilities).

IV.3IV.3IV.3 BMP Selection and Project Conformance Analysis Low Impact Development (LID) BMPs are required in addition to site design measures and source controls to reduce pollutants in storm water discharges. LID BMPs are engineered facilities that are designed to retain or biofilter runoff on the project site. The 4th Term MS4 Storm Water Permit for South Orange County (Order R9-2009-0002) requires the evaluation and use of LID features and techniques to infiltrate, filter, store, evaporate or retain runoff close to the source of runoff. If on-site retention LID BMPs are technically infeasible, LID biofiltration BMPs may treat any volume that is not retained on-site by the LID BMPs. Due to the flow through design of biofiltration BMPs, the total volume of the BMP, including pore spaces and pre-filter detention volume, must be sized to hold at least 0.75 times the design storm volume that is not retained onsite by LID retention BMPs. The following sections summarize the LID BMPs proposed for the project in accordance with the permit hierarchy and performance criteria outlined in Section IV.1.
IV.3.1 Hydrologic Source Controls (HSCs) Hydrologic source controls (HSCs) can be considered to be a hybrid between site design practices and LID BMPs. HSCs are distinguished from site design BMPs in that they do not reduce the tributary area or reduce the imperviousness of a drainage area; rather they reduce the runoff volume that would result from a drainage area with a given imperviousness compared to what would result if HSCs were not used.

The project will utilize HSCs (impervious area dispersion) within a portion of Lot E that drains away from the larger drainage area for biotreatment. Within this area (public park, to be dedicated to the City of Dana Point), the sidewalks and hardscape will drain to adjacent landscaping. Based on the capture efficiency calculations, the large amount of landscaping within this area is sufficient to treat runoff from the adjacent impervious surfaces in accordance with the Model WQMP and TGD (meets 80% minimum average annual capture efficiency). Calculations and associated worksheets are included in Attachment E.

IV.3.2 Infiltration BMPs Infiltration BMPs are LID BMPs that capture, store and infiltrate storm water runoff. These BMPs are engineered to store a specified volume of water and have no design surface discharge (underdrain or outlet structure) until this volume is exceeded. Examples of infiltration BMPs include infiltration trenches, bioretention without underdrains, drywells, permeable pavement, and underground infiltration galleries.

As discussed in Section III, the project site is also located in an area with shallow (or high) groundwater levels, approximately between 5-10 feet below ground surface. Due to the presence of shallow groundwater, on-site infiltration of storm water runoff is considered infeasible. In addition, the subject site is located in an area that has been identified as being potentially susceptible to liquefaction. Therefore, infiltration BMPs will not be utilized on-site.
IV.3.3 Evapotranspiration & Rainwater Harvesting BMPs Evapotranspiration BMPs are a class of retention BMPs that discharges stored volume predominately to ET, though some infiltration may occur. ET includes both evaporation and transpiration, and ET BMPs may incorporate one or more of these processes. BMPs must be designed to achieve the maximum feasible ET, where required to demonstrate that the maximum amount of water has been retained on-site. Since ET is not the sole process in these BMPs, specific design and sizing criteria have not been developed for ET-based BMPs.

Harvest and use (aka. Rainwater Harvesting) BMPs are LID BMPs that capture and store storm water runoff for later use. These BMPs are engineered to store a specified volume of water and have no design surface discharge until this volume is exceeded. Harvest and use BMPs include both above-ground and below- ground cisterns. Examples of uses for harvested water include irrigation, toilet and urinal flushing, vehicle washing, evaporative cooling, industrial processes and other non-potable uses.

For the purposes of evaluating feasibility in this WQMP, the Effective Irrigated Area to Tributary Area (EIATA) ratio tool was utilized in accordance with Appendix X of the Model WQMP’s Technical Guidance Document (TGD), dated December 20, 2013. The EIATA ratio is calculated as follows:
( × L) = ( × )
Where: EIATA = effective irrigated area to tributary ration (ac/ac) LA = landscape area irrigated with harvested water (square feet) KL = landscape coefficient (see Table X.8 of the TGD) IE = irrigation efficiency (assumed 90%)
For a system to be considered “feasible”, the system must be designed with a storage volume equal to the Design Capture Volume (DCV) from the tributary area and achieve more than 40% capture. The system must also be able to drawdown in 30 days to meet the 40% capture value. In addition, Table X.8 of the Technical Guidance Document sets forth the minimum demand thresholds / minimum irrigated area for

IV.3.4 Biofiltration BMPs Biofiltration BMPs are a class of LID BMPs that reduce storm water volume to the maximum extent practicable, treat storm water using a suite of treatment mechanisms characteristic of biologically active systems, and discharge water to the downstream storm drain system or directly to receiving waters. Treatment mechanisms include media filtration (though biologically-active media), vegetative filtration (straining, sedimentation, interception, and stabilization of particles resulting from shallow flow through vegetation), general sorption processes (i.e., absorption, adsorption, ion-exchange, precipitation, surface complexation), biologically-mediated transformations, and other processes to address both suspended and dissolved constituents. Examples of biofiltration BMPs include bioretention with underdrains, storm water planters, and some proprietary biotreatment systems.

Since both infiltration and harvest and reuse are considered infeasible, runoff from the project site will be treated through the use of biofiltration BMPs: proprietary biotreatment systems (Modular Wetlands) with upstream detention. In accordance with the Model WQMP and TGD, the biofiltration BMPs will be sized to treat runoff from the Design Capture Storm (85th percentile, 24-hour). Locations and tributary drainage areas are shown on the WQMP Exhibit included in Attachment C. Detailed calculations, associated TGD Worksheets and BMP details are included in Attachment E. Operation and maintenance details are included in Section V and Attachment B (O&M Plan).
Modular Wetlands by Modular Wetlands Systems, Inc. are proprietary biotreatment systems that utilize multi-stage treatment processes including screening media filtration, settling, and biofiltration. The pre- treatment chamber contains the first three stages of treatment, and includes a catch basin inlet filter to capture trash, debris, gross solids and sediments, a settling chamber for separating out larger solids, and a media filter cartridge for capturing fine TSS, metals, nutrients, and bacteria. Runoff then flows through the wetland chamber where treatment is achieved through a variety of physical, chemical, and biological processes. As storm water passes down through the planting soil, pollutants are filtered, adsorbed, biodegrated and sequestered by the soil and plants, functioning similar to bioretention systems. The discharge chamber at the end of the unit collects treated flows and discharges back into the storm drain system.
Due to the use of flow through design biofiltration BMPs (Modular Wetlands), storage of at least 75% of the Design Capture Volume is required for water quality treatment. Per Permit R9-2009-0002 (p.35), “Due to the flow through design of biofiltration BMPs, the total volume of the BMP, including pore spaces and prefilter detention volume, must be sized to hold at least 0.75 times the design storm volume that is
AG/A&M DOHENY, LLC Section IV Page 23 Date Prepared/Revised: April 1, 2014 SOC PRELIMINARY WATER QUALITY MANAGEMENT PLAN (P-WQMP) VTTM 17146 Site Development Permit No. SDP13-0015 APN 668-271-03 & 04 not retained onsite by LID retention BMPs.” To satisfy this requirement, 75% of the Design Capture Volume will be detained upstream of the proposed biofiltration BMP. The permit language does not specify the rate at which the prefilter volume can be released to the downstream biofiltration BMP. The required Treatment DCV is calculated in the WQMP is 20,044 cubic feet and 75% of this volume is 15,033 cubic feet. To meet the Permit criteria, 15,033 cubic feet of prefilter runoff will be stored in a detention chamber upstream of the Modular Wetland unit and pumped at a rate that will allow the unit to treat the full Treatment DCV (20,044 ft3). Once treated, the discharge from the wetland unit will flow to the large discharge pump. The detention system, as part of the storm drain system, will be placed in the drive aisles within the project near the downstream biofiltration BMPs (pending final design).
There will be an offline detention chamber that will take low flows as diverted from the full site drainage flows. This chamber will be a 60”RCP for 760 L.F., which provides the 75% volume, 15,033 cubic feet, when factoring in that the pump will engage before the entire detention system is full. These flows will be pumped and drain to the modular wetland system. The detention system for the main storm flows will be within the drive aisles of the project and will be an additional 2,040LF of 39” RCP, i.e. two separate detention locations. This system provides an additional 16,910 cf of pre-filter volume storage upstream in addition to the low flow detention system.
Catch basin inlet filters will provide pretreatment of runoff prior to draining into the detention system. These filters are discussed further under Section IV.4.3 (Treatment Control BMPs).
