Goal 13 - Floodplains
Reduce the severity and frequency of flooding and high water by preserving and increasing the existing water storage capacity below 100-year flood elevations on all waterbodies within MCWD.
The primary strategy in the management of stormwater and prevention of flooding in the Painter Creek subwatershed is the preservation of the stormwater storage. Key areas identified in this plan for conservation include wetlands that provide floodplain storage as well as channel and stream floodplain and riparian zones.
Desired Outcomes: No net loss of floodplain storage.
Metrics: Acres net floodplain fill.
Goal 13.1 - Painter Creek
Preserve the existing water storage capacity below the 100-year event elevation.
- Minimize development below the 100-year event elevation.
- No net loss of the large wetland complexes that provide substantial upstream stormwater storage within this subwatershed.
- Encourage the development and maintenance of depressional storage within the subwatershed.
- Promote the acceptability of minor flooding within the floodplain.
Goal 13.2 - Painter Creek
Utilize District hydrologic and hydraulic data to identify potential public infrastructure high water impacts.
- The HHPLS noted that the 100-year water level was expected to overtop one public street and two private driveways. Local plans should identify these observed or potential locations and assess whether the risk of occasional flooding is acceptable or should be addressed. Assist LGUs in determining specific impacts and potential improvements.
