4.13 Floodplains

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.


Flood Insurance Studies have identified no floodplain in the Schutz Lake subwatershed. However, managing stormwater flows within this subwatershed is still important to help reduce the severity and frequency of localized flooding within the subwatershed. The primary strategy in the management of stormwater in the Schutz Lake subwatershed is the preservation of the existing stormwater storage provided by wetlands. Additional storage could be provided through the creation of depressional storage areas on new developments.

Desired Outcomes: No net loss of wetland storage.

Metrics: Acres net wetland fill.

Goal 13.1 - Schutz Lake

Preserve the existing water storage capacity.


  1. Minimize development in low-lying areas.
  2. No net loss of the large wetland complexes that provide substantial upstream stormwater storage within this subwatershed.
  3. Encourage the development and maintenance of depressional storage within the subwatershed.

Goal 13.2 - Schutz Lake

Utilize District hydrologic and hydraulic data to identify potential public infrastructure high water impacts.


  1. The HHPLS noted that the 100-year water level was predicted to overtop the culvert outletting the wetland north of Schutz Lake. This culvert is in poor condition. 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.
