Background

  • New Development Projects
  • Stormwater quality retention requirements
  • Hydromodification requirements (Larger BMPs)

An Alternative Compliance Option is available 42

Watershed Management Area Analysis

  • How data will be used
  • Land Use – Evaluate potential impacts resulting from land development
  • Hydrologic Processes – Identify opportunities for enhanced infiltration
  • Streams and Channels – Assess stream stability
  • Coarse sediment areas – Identify areas of sediment supply which

contributes to stream stability 23

Dry Weather Field Screening

What is necessary?

  • Inspect 80% of Major Outfalls
  • 2x/Year
  • Visual Observations focused on FLOW

What is the purpose?

  • Source identification and elimination
  • Prioritization of outfalls – persistent flow
  • Calculate/estimate non-storm water volumes and

pollutant loads

  • Identify reductions in non-storm water flows and illicit
  • Evaluate strategies
