Sections:
16.102.020 Provisions for SUSMP requirements.
16.102.040 Site design stormwater treatment credits.
16.102.050 Alternative methods for achieving treatment requirements.
16.102.010 Limitations.
Where requirements of this division conflict with established local codes (e.g., specific language of signage used on storm drain stenciling), the City Council may continue the local practice and modify this division to be consistent with the code, except to the extent that the standards in this division are more stringent than those under local codes, such more stringent standards shall apply. (Ord. 671 § 33, 2008; Ord. 569 § 2, 2002)
16.102.020 Provisions for SUSMP requirements.
A. The requirements of this division shall be incorporated into the project design and shown on the plans prior to approval of discretionary permits.
B. For projects requiring only ministerial permits, the requirements of this division shall be incorporated into the project design and shown on the plans prior to the issuance of any ministerial permits.
C. City departments carrying out public projects that are not required to obtain permits shall be responsible for ensuring the requirements of this division are incorporated into the project design and shown on the plans prior to bidding for construction contracts, or equivalent. For public projects the requirements of this division must be incorporated into the project design and shown on the plans before allowing the project to commence.
D. City departments responsible for implementing this division and the respective roles and responsibilities of these departments are identified in the City’s Jurisdictional Urban Runoff Management Plan. (Ord. 671 § 34, 2008; Ord. 569 § 2, 2002)
16.102.030 Implementation.
A. All priority projects shall implement stormwater BMPs according to the provisions of the City of Poway Local SUSMP, including:
1. LID and site design BMPs;
2. Source control BMPs; and
3. Structural treatment BMPs after the pollutants and conditions of concern have been identified.
B. Stormwater BMPs shall be considered and implemented where expressly required by this division and, if not so required, where determined applicable and feasible by the Director of Development Services. The stormwater BMPs shall adhere to the requirements of this division and the City of Poway Local SUSMP, and shall be correctly designed, implemented, and maintained so as to remove pollutants to the maximum extent practicable. A flow chart summarizing the stormwater BMP selection procedure is provided in Figure 1. (Ord. 702 § 4, 2010; Ord. 671 §§ 35, 36, 2008; Ord. 569 § 2, 2002)
16.102.040 Site design stormwater treatment credits.
The Copermittees may develop and submit for public review and comment and Regional Water Quality Control Board (RWQCB) approval a regional model site design stormwater treatment credits program that allows reductions in the volume or flow of stormwater that must be captured or treated on a project in return for the inclusion of specified project design features in the project. The model site design stormwater treatment credits program shall be deemed to be a part of this division following RWQCB and City Council approval. Any such model program shall specify the conditions under which project proponents can be credited for the use of site design features and low impact development techniques that can reduce the volume of stormwater runoff, preserve natural areas, and minimize the pollutant loads generated and potentially discharged from the site. Any site design stormwater treatment credits program implemented shall be consistent and compliant with this division and approved by the City Council. (Ord. 671 § 37, 2008; Ord. 569 § 2, 2002)
16.102.050 Alternative methods for achieving treatment requirements.
The City may choose to implement the Local Equivalent Area Drainage (LEAD) Method as proposed by the City of San Diego to meet treatment BMP requirements. Any alternative treatment must meet the following criteria:
A. The alternative treatment area shall be located within the proximity of the project;
B. The alternative treatment area shall discharge to the same receiving water as the project;
C. The alternative treatment area shall be equivalent to or greater than the project footprint;
D. The alternative treatment area shall have an equivalent or greater impervious surface area than the project;
E. The alternative treatment area shall have an equivalent or greater pollutant load than the project;
F. LID and source control BMPs shall be required in the project design; and
G. Alternative treatments shall be limited to redevelopment or infill projects. (Ord. 702 § 5, 2010; Ord. 671 § 38, 2008)
