  1. Water Quality Management Plansfor theSanta Margarita WatershedofRiverside County Basic Training April 2011 Edition Minor Changes April 2012 Updated June 2013

  2. Why are we here? • Storm water and urban runoff from areas of new development and redevelopment must be managed to control impacts to: • Beneficial uses of receiving waters; • Integrity of streams and channels; and • Natural habitats. • City and county staff are responsible for implementing development regulations within their jurisdiction, including the Water Quality Management Plan program. • The development community is responsible for complying with regulations that require urban runoff quality and quantity management be a part of most new projects.

  3. Training Session Objectives To learn about current requirements for Project-Specific Water Quality Management Plans for new development and redevelopment projects in the Riverside County Santa Margarita River Watershed & To learn about upcoming changes to these requirements.

  10. Riverside CountyDrainage Area Management Plan (DAMP) • Describes urban runoff management strategies planned by the municipal NPDES permit holders • Addresses the prescriptive and stringent requirements in the 2004 Santa Margarita River Watershed Stormwater Permit • Requirements remain in effect until the Regional board approves compliance documents submitted under the 2010 Stormwater Permit. • Status… • Updated April 2007 • http://rcflood.org/NPDES/ Primarily a tool for Agency Staff

  11. Riverside CountyDrainage Area Management Plan (DAMP) • Will the requirements in the permits and strategies described in the DAMP ever change? • Yes! • What’s driving the changes in requirements and strategies? • The most recent municipal NPDES storm water permit • Riverside County – Santa Margarita River Watershed Permit • Order No. R9-2010-0016, NPDES No. CAS0108766 • Issued November 10, 2010

  12. Riverside County Municipal NPDES PermitsSanta Margarita River Watershed Permittees • Riverside County Flood Control and Water Conservation District  • County of Riverside  • Murrieta  • Temecula • Wildomar  Listed as a Permittee under the SAR & SMR Watershed permits. By agreement with the Regional Boards, local program based on SMR permit.

  13. Riverside CountyDrainage Area Management Plan (DAMP) • When will the WQMP program changes take place? • Changes will be phased in over time • Santa Margarita River Watershed • Template to RWQCB by June 30, 2012 • Implementation date TBD after July 30, 2012 • An overview of the program changes, or evolution, will be discussed later today. • In the meantime… • Continue to implement the strategies and programs that have been in place for many years now! • Those strategies and programs are the focus of today’s training.

  17. Knowing your project category is key to understanding the requirements for the project! Three Project Categories Development Project Review, Approval, Permitting, And Inspection Process • Redevelopment • New development • Other development Today, we’ll look briefly at definitions of each category. For detailed definitions, consult program Guidance Documents (DAMP/WQMP).

  29. Significant Redevelopment New Development & Significant Redevelopment Projects • Where a Priority Project is a Redevelopment Project and replaces • < 50% of the impervious surfaces on an existing developed site, and • The site was not previously subject to Priority Development Project requirements, then • The WQMP design standards apply only to the addition or replacement, and not to the entire developed site. • Where a Priority Project is a Redevelopment Project and replaces • ≥ 50% of the impervious surfaces on an existing developed site, then • The WQMP design standards apply to the entire development. The 50% Rule for Redevelopment Projects

  34. First Things First!What Is A WQMP? Preliminary Water Quality Management Plan During Entitlement* • Water • Quality • Management • Plan • The WQMP is a project-specific plan of Best Management Practices (BMPs), including site design, source controls, and treatment controls, to address post-construction urban runoff quality and quantity to protect receiving waters. • A project-specific WQMP must be submitted and approved prior to the first discretionary project approval or permit for all Significant Redevelopment and New Development projects. WQMP

  35. PROJECT PLANNING AND DESIGN PROJECT CONSTRUCTION PROJECT O&M RAW LAND REDEVELOPMENT This is the domain of the Storm Water Pollution Prevention Plan The SWPPP Project Lifecycle and WQMPs DEVELOPMENT This is the domain of the Water Quality Management Plan The WQMP

  36. PROJECT PLANNING AND DESIGN PROJECT CONSTRUCTION PROJECT O&M RAW LAND REDEVELOPMENT This is the domain of the Storm Water Pollution Prevention Plan The SWPPP Project Lifecycle and WQMPs DEVELOPMENT Pollution Prevention Is Now Part Of Every Project Stage! This is the domain of the Water Quality Management Plan The WQMP

  37. PreliminaryProject-Specific WQMP Preliminary Water Quality Management Plan During Entitlement* • A Preliminary Project-Specific WQMP may be required • When a project is subject to discretionary approval during the planning and entitlement process (tentative tract map, parcel map, or subdivision map) and • Will be subject to ministerial approvals for subsequent grading or building permits • Submit WQMP with project application

  38. PreliminaryProject-Specific WQMP Preliminary Water Quality Management Plan During Entitlement* • Level of detail in a Preliminary Project-Specific WQMP will depend on the overall project design at the time project approval is sought. • Key point – The Preliminary WQMP needs to be specific enough to identify the land required for BMP implementation! • A Final Project-Specific WQMP that is in substantial conformance with the Preliminary Project-Specific WQMP (and in full conformance with the WQMP Guidance) will be required prior to issuance of any building or grading permit. Many cities have adopted City-specific requirements to guide the Preliminary WQMP process

  47. Mandatory Notes forConstruction Plans Building or Grading Permits • DAMP Requirements Prior to Grading/Building Permits • Requires a number of standard notes on construction plans as part of the grading and building permit process. • These notes are detailed in the DAMP and won’t be covered here.

  48. Grading and Building PermitsAre Issued After… Building or Grading Permits • For Redevelopment and New Development Projects… • Final Project-Specific WQMP is approved. • Plan Check verifies that… • BMPs from WQMP are incorporated into plans. • Standard Notes have been placed on plans. • Conditions of Approval have been met. • For Other Projects… • Construction plans incorporate site design and source control BMPs. • Standard Notes have been placed on plans. • Condition of Approval have been met.
