challenges and opportunities for managing storm water and dry weather runoff

  • Identify and prioritize storm water and dry weather runoff

projects that provide multiple benefits to help achieve watershed and regional planning goals

slide-23
SLIDE 23

Watershed Priorities: Water Resource Priorities

  • Implement water quality improvements to support TMDL

goals

  • Reduce discharge into 303(d) Listed Impaired

Waterbodies

  • Implement storm water capture/groundwater recharge

into groundwater basins (where feasible)

  • Other priorities?

23 10/4/2017

slide-24
SLIDE 24

Watershed Priorities: Water Quality

  • Mercury / Methylmercury
  • Diazinon
  • Chlorpyrifos
  • Selenium
  • Salt / Salinity
  • Boron
  • Diuron
  • Low Dissolved Oxygen

(Nitrogen (Ammonia and Nitrates) and Phosphorus)

  • Bacteria

Project Solicitation

  • Utilizing Opti Data

Management System

  • Requesting same basic

project info as ESIRWM

  • Location, description, status,

etc.

  • Requesting additional info

specific to SWRP:

  • Project eligibility
  • Watershed priorities
  • SWRP Main Benefits and

Additional Benefits

Project Prioritization

  • [A Storm Water Resource Plan] shall use measurable factors to

identify, quantify, and prioritize potential storm water and dry weather runoff capture projects. (Wat. Code, § 10562, subd. (e).)

  • Project Eligibility (Fatal Flaw Analysis)
  • Each Project must meet all of the following:

Can the project be sponsored by an eligible applicant? Yes/No Is the project a storm water or dry weather runoff project? Yes/No Does the project provide 2 or more SWRP Main Benefits? Yes/No Does the project provide at least one SWRP Additional Benefit? Yes/No

slide-30
SLIDE 30

Prioritization Guidance

  • Prioritize individual projects or programs that:
  • Are supported by entities that have created permanent, local, or

regional funding

  • Use a metrics-driven approach and geospatial analysis of multiple

benefits to maximize water supply, water quality, flood management, environmental, and community benefits within the watershed

  • Are located on public lands
  • Augment local water supplies
  • Preserve, restore, or enhance watershed processes (yield water quality

benefits and support beneficial uses)

  • Create or restore habitat, open space, parks, recreation, or green open

space in DACs with a deficit of such areas.

slide-31
SLIDE 31

Proposed Prioritization Approach

  • Eligible Projects receive credit for:
  • Having permanent, local, or regional funding in place (4 points)
  • Addressing regional watershed priorities
  • Providing SWRP Main Benefits and Additional Benefits
  • Projects prioritized based on points awarded to each project

Regional Watershed Priorities Points Located on public land? 4 Help achieve the goals of an existing TMDL? 4 Reduces discharges into a 303(d) Water Body? 2 Identified in an existing study/planning document? 2 Recharges storm water into a groundwater basin? 4 SWRP Main Benefits and Additional Benefits Points Providing SWRP Main Benefits Points per benefit provided Additional points if a quantitative metric is provided 4 2 Providing SWRP Additional Benefits Points per benefit provided Additional points if a quantitative metric is provided 2 1 Technical Document used to quantify benefits Design Document Environmental Assessment/EIR Feasibility Study Another Planning Document 4 3 2 1
