SR-071310-7BCity Council Meeting: July 13, 2010 Agenda Item: 7=~ To: Mayor and City Council From: Dean Kubani, Director of the Office of Sustainability and the Environment Subject: Introduction and First Reading of an Ordinance to update and modify Chapter 7.10, Urban Runoff Pollution Control. Recommended Action Staff recommends that City Council introduce for first reading an amended Urban Runoff Pollution Control Ordinance that will apply to new development, construction sites and existing parcels in the City. Executive Summary The attached modified Urban Runoff Pollution Control Ordinance (Ordinance) updates the existing ordinance and includes all changes recommended by the Task Force on the Environment on June 22, 2010, The timely implementation of the modified Ordinance will ensure that Santa Monica remains on the leading edge of environmental protection measures and that the urban runoff environmental impacts of upcoming and future city-wide building and infrastructure improvement projects are significantly reduced. The modified Ordinance updates the requirements and exemptions for new and re-development projects to install post-construction structural devices to collect storm water for treatment, keeping this potential water pollution source out of the Santa Monica Bay (Bay). The modified Ordinance also requires construction sites to take similar measures, and requires that existing properties implement good housekeeping practices to protect the Bay. The objective. of the Ordinance is to significantly reduce environmental impacts related to urban runoff and to promote a major shift towards sustainability in land use design and local water resource management. No financial impact results from this action. Discussion On June 8, 2010 City Council introduced for first reading an ordinance to update and modify Chapter 7.10, Urban Runoff Pollution Control. At that meeting Council requested that the draft ordinance be amended to require all municipal street paving projects of $1 million or more to comply with the ordinance. Council also requested that the draft ordinance be forwarded to the City's Task Force on the Environment for review and comment prior to the second reading on June 22, 2010. A subcommittee of the Task Force on the Environment reviewed the draft ordinance and presented several recommended revisions at the June 22, 2010 Council meeting. Council directed staff to review the Task Force recommendations and return with a revised draft ordinance. The recommendations made by the Task Force on the Environment subcommittee are listed below: 1. Eliminate the "treat and release" option from the runoff ordinance. a. For example -eliminate "treat and release" in 2 sections under 7.10.050 (b) Urban runoff mitigation plan. 2. Under 7.10.020: Add the following - "All new and significant redevelopment shall capture and use, infiltrate or evapotranspire 100 percent of the runoff generated from the 3/ inch storm." 3. Under 7.10.030 (m): Under New/Re-development definitions, threshold (2), order change MOVE (a) to (d), and MOVE UP the other 3. CHANGE (in the old (a) now (d)) 5,000 sq ft to 2,500 sq ft. 4. Where BMP options are mentioned, 7.10.050 (b) such as store/use, infiltration, ADD evapo-transpiration as an equivalent LID-BMP optiori. 5. Under 7.10.050 (c) (2) (a): List LID BMPs, CHANGE Biofilter to Bioretention, and any other locations in the ordinance, with qualifier that this Bioretention will harvest the design storm, and any runoff in exceedence of the design storm can be discharged to the MS4. 6. Under 7.10.050 (i): for the green street option for the city, CHANGE $1 million figure to $500,000 7. Under 7.10.050 (s): REPLACE "structural or treatment control" with "Low Impact Development" 2 8. Under 7.10.070, (a): the $500 fine is not defined as per day or per violation. Change to $500 per violation per day. Staff has reviewed these recommendations and has incorporated them into the attached revised draft ordinance in the appropriate locations. In addition to these changes, staff has changed the basis for the calculation of the Unit Cost for the in-lieu. fee from a 3-year average of cost-per-gallon of water for the City to construct post- construction BMPs on City property to a 5-year average. This change will provide a more representative sample of projects for calculation of the Unit Cost. As revised, section 7.10.050 now requires that an applicant must meet urban runoff mitigation requirements through the use of onsite low impact development (LID) best management practices (BMPs). If the applicant demonstrates that onsite LID BMPs are infeasible then they will be allowed to meet the requirements through the use of LID BMPs at an approved offsite location. Treat and release BMPs are no longer an option for meeting the urban runoff mitigation requirements unless the applicant demonstrates that the City is required by State or federal law to provide that option. Staff believes that it is highly unlikely that this demonstration can be made but believes it is an appropriate safeguard to include in the ordinance. 3 Financial Impacts & Budget Actions No financial impact results from this action.

(a~) Urban runoff flows from individual properties onto the-streets and alleys, then through storm drains to the beaches. It is therefore in the public interest to ensure that both .public and private drainage systems are properly maintained; in order to facilitate the proper functioning of the 5 City's storm and surface water drainage system, and to prevent pollutants from entering the Santa Monica Bay.

(e) Southern California experiences cycles of drought which can lead to dramatic water shortages. The currant state-wide declaration of drought is a signal to local governments to promote sustainable uses of non-traditional, non-potable local water supplies such as rain water and storm water, in place of more valuable potable water which is often imported from distant watersheds at great environmental costs. (fl To promote sustainable solutions for urban runoff pollution and the use of local non-potable water supplies, the City strongly encourages the use of dry weather runoff, rain water and storm water harvested by post-construction BMPs which collect and store runoff for non-potable onsite uses.

Commencing on July 1, 2011 and on July 1S' of each fiscal dear thereafter the Urban Runoff Reduction Fee shall be adjusted based on changes in constructions costs. The Urban Runoff Reduction Fee shall be used exclusively to construct Low Impact Development post- construction BMPs designed to achieve at least the same level of water quality protection as if all of the runoff was retained on site and to implement the strategies of the 5-Year Low Impact Development Plan in support of the City's Watershed Management Plan. (s) An applicant shall not be authorized to pay an Urban Runoff Reduction Fee for the nine specified land use categories found in the SUSMP but instead must install Low Impact Development post- construction BMP's unless the applicant demonstrates to the Director of the Department of Public Works or his or her designee the infeasibility of implementing these requirements. Recognized circumstances demonstrating infeasibility include: (i) extreme limitations of space for treatment; (ii) unfavorable or unstable soil conditions at a site to attempt infiltration and (iii) risk of groundwater contamination because a known 32 unconfined aquifer lies beneath the land surface or an existing or potential underground source of drinking water is less than ten feet from the soil surface. Any other justification for impracticabilityrnust be approved by the Regional Board. (t) An applicant and anv successor in interest shall comply with the Urban Runoff Mitigation Plan, including installation of anv required BMP and its maintenance.
