PURPOSE:
Approval of an Intergovernmental Agreement with Mile High Flood District for funding of Major Drainageway Plan and Flood Hazard Area Delineation for Slaughterhouse Gulch.
LONG-TERM OUTCOME(S) SERVED:
Safe Community; High-Quality Governance; Sustainable Community with Natural Beauty
DISCUSSION:
Watershed planning is an important way to help protect people and property against flooding, erosion, and stormwater quality problems. These plans contain a strategy and work plan to identify flood risk management projects, guide new land development projects and identify high risk areas.
The Slaughterhouse Gulch drainageway was originally studied in 1974, and subsequently updated in 1982, 1983, 1992 and 1993.
Mile High Flood District (MHFD) along with project sponsors, Southeast Metro Stormwater Authority (SEMSWA) and the City of Littleton, are proposing updates to the Major Drainageway Plan (MDP) and Floodplain Hazard Area Delineation (FHAD). The studies will evaluate the hydrology and floodplain limits of Slaughterhouse Gulch in consideration of new rainfall data and development that has occurred in the basin since the previous study in 1993. The MDP will provide a conceptual design of recommended improvements in the watershed, including estimated costs. The MDP will be used as a guide for implementing drainage improvements. The FHAD study will identify flood risk information and boundaries. The FHAD will then be used to update the FEMA floodplain maps as a physical map revision, updating the regulatory boundaries of the floodplain.
