Issues
• Should CWMTF require applicants to:
– Have floodplain management ordinances?
– Participate in FEMA National Flood Insurance
Program (NFIP)?
– Have stream buffer ordinances?
– Have sedimentation and erosion control
ordinances?
– Have a SW Capital Improvement Program?
– Have a SW utility?
Grant application and award process
Applications accepted annually: February 1
Field representatives visit project sites: spring/summer
Staff review, score, rank applications: spring/summer
Staff recommends to Board of Trustees and Board
selects projects for funding: fall
Competitive grant applications
Annual appropriation has decreased, competition has increased
Demonstrate water quality problems and solutions
Link to overall watershed efforts
Preference for restoration and stormwater: headwaters, water supply watersheds, urban 303(d) streams, eliminate ocean outfalls
Matching funds, preferably in hand
If for construction, ready to start
Keep in mind for stormwater and
restoration projects
Property owners must be on-board
Permanent easements not required for municipal
stormwater BMPs – O&M plans instead
Integrate stormwater management and stream
restoration
Manage runoff volume, recharge groundwater, and
harvest and reuse rainwater
