Watershed Management Area Analysis Update
Stuart McKibbin
Riverside County Flood Control and Water Conservation District
21
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

Objectives
Long Term Monitoring Stations
What is necessary?• Minimum of one station
• Representative of Receiving Water Conditions
What is the purpose?• Status and Trends – short/long term
improvements
• Progress to Goals
• Are strategies working?
• Are Beneficial Uses Protected?

Receiving Water Monitoring Question and Relationship to SMR Goals (example)
39
Monitoring Question:
What are the Total Nitrogen and Total Phosphorus loadings in the SMR at the base of the Upper Watershed? How are they changing over time?
Goal:
Reduce dry weather loads in receiving waters by 10%.

Wet Weather Monitoring
41
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

Non-stormwater Persistent Flow MonitoringWhat is necessary?• Monitor top 5 sites (per jurisdiction)• 2x/Year• Visual Observations + Chemistry
What is the purpose?• Source identification and elimination• Calculate/estimate non-storm water volumes and
pollutant loads• Identify reductions in non-storm water flows and
illicit• Evaluate strategies
44
Non-stormwater Persistent Flow Monitoring Approach
49
• Persistent Flow
• Contribute to HPWQC
• Sources
• Target Areas
Prioritize
• Elimination
• Not a source of pollutants
• Authorized
Monitor• Eliminate one
• Select next highest
Reprioritize
Non-stormwater Persistent Flow Monitoring Example
46
Wet Weather Outfall Monitoring
What is necessary?• 5 Sites per WMA• 1 Site per Permittee• 1 Storm Event per Year – HPWQC, Impairments
What is the purpose?• Calculate/estimate stormwater volumes and
pollutant loads and changes over time
• Validate WQIP assumptions (e.g., land use estimates)
• Evaluate strategies

Special StudiesProvision D.3
What is necessary?• 2 Studies per WMA
• 1 Regional Study (can substitute for WMA study)
What is the purpose?• Relate to the HPWQC
• Identify sources of pollutants and/or stressors 51

Special Studies Monitoring Question and Relationship to SMR Goals (example)
53
Monitoring Question:
Are there sources of pollutants causing exceedances of targets that are outside of Copermittee control?
If an Estuary related Goal is not met (e.g., interim targets for eutrophic indicators):
Rainbow CreekTotal Maximum Daily Load for Total Nitrogen and Total PhosphorusAttachment E
• Incorporate the Sampling and Analysis Plan for Rainbow Creek
• Perform monitoring to demonstrate progress towards TMDL compliance targets
