General Project Information:
Project Name: STORM WATER STANDARDS MANUAL UPDATE
Project No. 435930 / SCH No. Pending
Community Plan Area: Citywide
Council Districts: All City Council Districts

APPLICANT: City of San Diego Transportation & Storm Water Department - Storm Water Division

SUBJECT: CITY COUNCIL APPROVAL OF THE STORM WATER STANDARDS MANUAL UPDATE to update the City’s storm water-related requirements for land development and construction activities in accordance with the 2013 Municipal Permit (Municipal Permit).

In accordance with the federal Clean Water Act, the San Diego Regional Water Quality Control Board (RWQCB) issues Municipal Storm Water National Pollutant Discharge Elimination System (NPDES) Permits (Municipal Permit) to municipalities that own and operate a municipal separate storm sewer system (MS4) that discharges into waters of the U.S. within the San Diego region. The RWQCB issued the first Municipal Permit to the City of San Diego and twenty (20) other municipalities (Co permittees) in the region in 1990, and has renewed it four times thereafter. In May 2013, the RWQCB adopted the most recent Municipal Permit, Order No. R9-2013-0001, as subsequently amended by Order No. R9-2015-0001.

The Municipal Permit requires all development projects, regardless of size, to implement source control Best Management Practices (BMPs) and site design Low Impact Development (LID) practices to minimize the generation of pollutants. While all development projects are required to implement source control and site design practices, the Municipal Permit has additional requirements for development projects that exceed size thresholds and/or fit under specific land use categories. These projects, referred to as Priority Development Projects (PDPs), are required to incorporate structural BMPs into the project plan to reduce the discharge of pollutants, and address potential hydromodification impacts from changes in flow and sediment supply. Projects that are not classified as PDPs are referred to as Standard Projects.

The Municipal Permit requires the City to implement storm water standards to address storm water pollution associated with private and public development projects during construction and post construction. The City of San Diego developed the first Storm Water Standards Manual in 2002, and updated it in 2008 and 2012 to comply with new requirements in subsequent Municipal Permits. The 2013 Municipal Permit requires the City to update its Storm Water Standards Manual (Manual Update) to incorporate additional requirements.

The Manual Update provides design concepts and methodologies to guide applicants in meeting the requirements of the 2013 Municipal Permit, Provision E.3.

The Manual Update, Part 1, addresses expanded and updated post-construction storm water requirements for Standard Projects and PDPs, and provides updated procedures for planning, selecting, and designing structural storm water BMPs based on the performance standards and requirements in the Municipal Permit.

Structural BMPs are engineered facilities that are designed to retain, detains, filters, removes, or prevents the release of pollutants to surface waters from development projects in perpetuity, after construction of a project is completed. Structural BMPs are a type of Low Impact Design that aims to mimic the natural hydrology to manage storm water pollutant on site. Structural BMPs utilize biological, chemical and physical processes to remove pollutants from storm water runoff before it’s discharged to water ways. Examples of structural BMPs are bioretention basins, infiltration trenches, rain gardens, vegetated swales, biofiltration basins, and planter boxes.

The Municipal Permit requires all Priority Development Projects (PDP) to implement structural BMPs to retain onsite pollutants contained in the volume of storm water runoff produced from a 24-hour 85th percentile storm event (referred to as Design Capture Volume, or DCV). If it is not technically feasible to implement retention BMPs for the full DCV onsite for a PDP, then the PDP is required to utilize biofiltration BMPs for the remaining volume not reliably retained. If biofiltration BMPs are not technically feasible, then the PDP is required to utilize flow-thru treatment control BMPs to treat runoff leaving the site and participate in alternative compliance to mitigate for the pollutants from the DCV not reliably retained onsite.

The Manual Update categorizes structural BMPs in three categories based on the unit processes utilized in the BMP design. The BMP selection from these categories is largely based on the site conditions.

Infiltration BMPs: BMPs that are designed to retain the full design capture volume. Structural BMPs in this category include the following:

Infiltration BMPs typically consist of an earthen basin with a flat bottom constructed in naturally pervious soils. Infiltration BMPs capture, store, and infiltrate storm water runoff into native soils.

Bioretention BMP facilities are vegetated surface water systems that filter water through vegetation and soil, or engineered media prior to infiltrating into native soils.

Permeable pavement BMPs allow for percolation through void spaces in the pavement surface into subsurface layers. The subsurface layers are designed to provide storage of storm water runoff so that outflows, primarily via infiltration into subgrade soils or release to the downstream conveyance system, can be at controlled rates.

Partial Infiltration BMPs: Infiltration of a significant portion of the DCV may be possible, but site factors may indicate that infiltration of the full DCV is either infeasible or not desirable. Structural BMPs in this category include the following:

Biofiltration with partial retention BMPs are shallow basins filled with treatment media and drainage rock that manage storm water runoff through infiltration, evapotranspiration, and biofiltration. These BMPs typically have an infiltration storage layer. The volume of biofiltered water above the infiltration storage layer is discharged via underdrain. Other components include a media layer and associated filtration rates, drainage layer with associated in-situ soil infiltration rates, and vegetation.

No Infiltration BMPs: Infiltration of any appreciable volume of the DCV should be avoided. Some incidental volume losses may be possible, but any appreciable quantity of infiltration would introduce undesirable conditions. Structural BMPs in this category include the following:

Harvest and use BMPs capture and store storm water runoff for later use. Uses of captured water may include irrigation demand, indoor non-potable demand, industrial process water demand, or other demands. Uses of captured water shall not result in runoff to storm drains or receiving waters.

Biofiltration BMPs are shallow basins filled with treatment media and drainage rock that treat storm water runoff by capturing and detaining inflows prior to controlled release through incidental infiltration, evapotranspiration, or discharge via underdrain or surface outlet structure. Biofiltration BMPs include impermeable liners located at the bottom of the BMP to prevent infiltration.

Flow-thru treatment control BMPs (vegetated swales, media filters, sand filters, dry extended detention basin, proprietary flow-thru treatment control) are structural, engineered facilities that are designed to remove pollutants from storm water runoff using treatment process that do not incorporate significant biological methods.

Detailed descriptions of the structural BMPs are included in Chapter 5 of the Manual Update. Fact sheets for sizing and designing BMPs are located in Appendix E of the Manual Update. In addition to satisfying pollutant control requirements, PDPs subject to hydromodification management requirements must provide flow control for post-project runoff to meet the flow control performance standard. Flow control for hydromodification management is typically accomplished using structural BMPs that may include any combination of infiltration basins; bioretention, biofiltration with partial retention, or biofiltration basins; or detention basins. Both storm water pollutant control and flow control for hydromodification management can be achieved within the same structural BMP(s) or by a series of structural BMP(s). Guidance on how to design these structural BMPs to satisfy both pollutant control and hydromodification management requirements is provided in Chapter 6 of the Manual Update.

Notable changes required by the Municipal Permit related to development planning requirements that have been incorporated in the Manual Update, Part 1 include:

Priority Development Projects Category: The size threshold for PDP categories has been reduced from 1 acre to 10,000 square feet of impervious area for commercial, industrial, mixed-use, and public development projects. Additionally, the size threshold for residential PDPs has been reduced from 10 dwelling units to 10,000 square feet of impervious area.

The RWQCB has announced that it intends to make further amendments to the 2013 Municipal Permit in November 2015 to change the PDP categories. The proposed amendments would increase the number of projects considered to be PDPs by including: (1) new and redevelopment projects that create and/or replace 5,000 square feet or more of impervious surface; and (2) new development projects or redevelopment projects that create and/or replace 5,000 square feet or more of impervious surface, that support automotive repair shops or retail gasoline outlets.

Pollutant Control Requirements: PDPs are required to implement structural BMPs to retain the 85th percentile storm event. For situations where on-site retention of the 85th percentile storm volume is not feasible, bio-filtration must be provided to satisfy specific performance standards.

Priority Development Project Exemption: Projects that either (1) redevelop existing paved alleys, streets, or roads OR (2) develop or retrofit paved sidewalks, bicycle lanes, or trails may be exempted from being required to meet PDP requirements if they include green infrastructure design elements in accordance with the USEPA document "Managing Wet Weather with Green Infrastructure - Municipal Handbook". The Manual Update provides further guidance on green streets design requirements for PDP exemptions. New or retrofit paved sidewalks, bicycle lanes, or trails may also be exempt if they are designed and constructed to direct storm water runoff to non-erodible permeable areas or are hydraulically disconnected from paved streets or roads.

Hydromodification Management BMP Requirements: The Manual Update continues to require the current Hydromodification Management criteria on PDPs with the following changes based on new requirements in the 2013 Municipal Permit: (a) exemptions from this requirement will be allowed in fewer cases, and exemptions for highly urbanized areas and for a portion of major river reaches are removed; (b) calculations for the increase of runoff volume from impervious surfaces must compare post-project runoff to runoff from a "pre-developed" condition, meaning the condition before existing impervious surfaces were added; and (c) sites that meet criteria for providing a natural source of coarse sediment that is critical for stream sediment replenishment need to either restrict development on those source areas or follow the project specific onsite measures as described in the Manual Update.

Alternative Compliance Option: The Municipal Permit provides off-site Alternative Compliance as an option for PDPs in lieu of implementing on-site structural BMPs to comply with pollutant control and hydromodification management requirements. The off-site alternative compliance may include off-site mitigation options in the following categories:

Stream or riparian area rehabilitation
Retrofit of existing infrastructure
Regional BMPs
Groundwater recharge
Water supply augmentation
Land purchase to preserve floodplain functions

The City intends to implement the alternative compliance program in two phases:

1) Phase I: Applicant Implemented Alternative Compliance Projects where the applicant is fully responsible for the project’s design, construction, operation, and long-term maintenance. Phase I is included in the Manual Update; however it will be utilized only if the Water Quality Equivalency (WQE) study is approved by the RWQCB executive officer. Once the RWQCB approves the WQE, the City has the discretion to allow PDP projects to utilize Phase I.

2) Phase II: Independent Alternative Compliance Projects which includes other options such as in lieu fee or a credit trading system. This phase is in the initial planning stage and is therefore not part of the project being analyzed in this mitigated negative declaration.

Additionally, Manual Update, Part 2, includes construction management requirements in accordance with the Municipal Permit. It provides guidance regarding required temporary storm water management controls during construction phase of development projects. There are no notable changes related to the construction management provisions in the Municipal Permit with the exception of deletion of the maximum grading limitation and the advanced treatment requirements. However the Construction BMP Standards, Part 2 of the Manual Update has been reformatted and updated to reflect City specific processes. The Manual Update provides more detailed guidance on required BMPs during the construction phase, inspection and documentation requirements, and includes storm water pollution control plan templates.

Recommended Finding:
The recommended finding that the project will not have a significant effect on the environment is based on an Initial Study and project revisions/conditions which now mitigate potentially significant environmental impacts in the following area(s): HISTORICAL RESOURCES (ARCHAEOLOGY), HISTORICAL RESOURCES (BUILT ENVIRONMENT), BIOLOGICAL RESOURCES, GEOLOGY, PALEONTOLOGICAL RESOURCES, LAND USE (MULTIPLE SPECIES CONSERVATION PROGRAM [MSCP]/MULTI-HABITAT PLANNING AREA [MHPA]).
