DRAFT

These conditions presuppose that we have already received the Stormwater Management Plan and Stormwater Maintenance Plan at initial application (as required by ordinance).

General (Prior to Final Map, Parcel Map, or Use and Reliance)
No Improvement Plans or Grading plans can be approved for this project until the applicant provides a design-level detailed plan and drainage report prepared by a registered engineer that includes pre-development drainage patterns and discharge rates for the project site. The plan shall provide information that proves the adequacy of BMPs selected, BMP location proposed, and sizing/configuration of BMPs. The report shall provide the detailed volume and velocity calculations; all to the satisfaction of the Director of Public Works.

Landscaping  (Prior to Final Map, Parcel Map, or Use and Reliance)
The applicant shall submit, for County review and approval, landscaping plans with characteristics that maximize infiltration, provide retention, reduce irrigation and storm runoff, use efficient irrigation, and minimize the use of fertilizers, herbicides and pesticides; all to the satisfaction of the Director of Planning and Land Use.

Post Construction Best Management Practices  (Prior to Final Map, Parcel Map, or Use and Reliance)
The applicant shall submit plans showing source control BMPs proposed as part of the project and a certified letter noting the implementation plans for said BMPs, to the satisfaction of the Director of Public Works. These features may be properly identified and included on the project’s improvement plans.

The applicant shall provide a buffer zone for natural water bodies on a plan showing each buffer zone and any proposed fencing. The buffer zone (s) proposed to provide stormwater protection and shown on the plan must be to the satisfaction of the Director of Public Works

The industrial applicant shall provide evidence of coverage under the State of California’s statewide General NPDES Permit for Storm Water Discharges Associated With Industrial Activities at all times, to the satisfaction of the Director of Public Works.

The applicant shall ensure that the grading and other construction activities meet the provisions specified in the California RWQCB, San Diego Region, Order 2001-01, and NPDES No. CAS0108758 – Section F.2, to the satisfaction of the Director of Public Works.

The applicant for a project that proposes to disturb more than 5 acres shall provide evidence of submitting a Notice of Intent (NOI) or an assigned Waste Discharge Identification number (WDID) under the State of California’s statewide General NPDES Permit for STORM WATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY (GENERAL PERMIT), to the satisfaction of the Director of Public Works

The applicant shall submit a final Structural Treatment BMP Maintenance plans for any structural treatment BMPs proposed as part of the project, for County review and approval. The mechanism must ensure ongoing long-term maintenance of these BMPs, all to the satisfaction of the Director of Public Works.

Prior to approval of any plans or maps for the project, the applicant shall submit a report (all to the satisfaction of the Director of Public Works) that updates information submitted at initial application and which:

Identifies any changes in affected receiving water bodies, applicable water-quality objectives (Regional Water Quality Control Board (RWQCB) and San Diego Association of Governments)

Identifies pollutants of concern,

Estimates post-construction discharge rates (with all BMPs in place)

Demonstrates that post-construction BMPs projects will reduce to the Maximum Extent Practicable the projects potential to add pollutants to storm water or to affect the flow rate or velocity of stormwater runoff after construction is completed.

Demonstrates that the post-construction BMPs incorporated into the project will prevent it from significantly degrading receiving water quality, or, causing or contributing to an exceedance of receiving water quality objectives

Explains why the projected pollutant loads will not cause a violation of the water quality objectives.

The applicant shall submit a detailed design-level plan and report that includes a combination of source control and structural treatment BMPs that at a minimum will:

  • Control the post-development peak storm water runoff discharge rates and velocities to maintain or reduce pre-development downstream erosion;

  • Conserve natural areas; Minimize pollutants of concern from urban runoff through implementation of source control BMPs;

  • Remove pollutants of concern from urban runoff through implementation of site design, source control, and structural treatment BMPs implemented close to pollutant sources and prior to discharging into receiving waters;

  • Minimize directly connected impervious areas;

  • Protect slopes and channels from eroding;

  • Include storm drain stenciling and signage;

  • Include properly designed outdoor material and trach storage areas;

  • Ensure that post-development runoff does not contain pollutant loads that have not been reduced to the maximum extent practicable.

These features may be included on the project’s improvement plans as long as they are properly identified; all to the satisfaction of the Director of Public Works

All post construction BMPs as required by the County’s Watershed Protection, Stormwater Management, and Discharge Control Ordinance, and Appendix A Stormwater Standards Manual, shall be shown in detail on the construction plans to the satisfaction of the Director of Public Works.

Construction  (Prior to Permit Issuance, Final Map, Parcel Map, or Use and Reliance)
The applicant shall ensure that the grading and other construction activities meet the provisions specified in the California RWQCB, San Diego Region, Order 2001-01, NPDES No. CAS0108758 – Section F.2, to the satisfaction of the Director of Public Works.

The applicant shall submit and then implement a Storm Water Pollution Prevention Plan (SWPPP), per State requirements, to manage storm water and non-storm water discharges from the site at all times. The SWPPP shall describe all BMPs to be implemented year round. Specific BMP implementation may be dependent upon wet or dry season operations. The SWPPP shall also emphasize that erosion prevention is the most important measure for keeping sediment on site during construction; all to the satisfaction of the Director of Public Works.

The applicant shall utilize sediment controls only as a supplement to erosion prevention for keeping sediment on-site during construction to the satisfaction of the Director of Public Works.

All construction and grading related BMPs shall be shown in detail on the construction plans, improvement plans, or grading plans submitted to the County to the satisfaction of the Director of Public Works.

The applicant shall clear and grade only those areas on the project site that are necessary for construction to the satisfaction of the Director of Public Works. These areas shall be clearly denoted on the plans and in the SWPPP.

The applicant shall minimize exposure time of disturbed soil areas through scheduling of disturbance activities and stormwater protection activities to the satisfaction of the Director of Public Works.

The applicant shall submit a schedule to the County for review and approval, with proposed dates, demonstrating the minimization of grading during the wet season and coinciding the grading with dry weather periods, permanent revegetation and landscaping as early as feasible, temporary stabilization and reseeding of disturbed soil areas as early as feasible, all to the satisfaction of the Director of Public Works. These features may be included on the project’s improvement plans or grading plans as long as they are properly identified

The applicant shall stabilize all slopes as required by the County’s Watershed Protection, Stormwater Management, and Discharge Control Ordinance, and Appendix A Stormwater Standards Manual, all to the satisfaction of the Director of Public Works.
