Study status: Complete
Pima County Regional Flood Control District has completed the Lee Moore Wash Basin Management Study to identify the drainage and flooding hazards within the watershed and develop alternatives to address those hazards. A Basin Management Study is a comprehensive study that estimates flood and erosion potential for a watershed, maps watercourses, identifies existing and potential problems and develops preliminary solutions and standards for sound floodplain and stormwater management.
The initial effort collected data to identify known flooding hazards and map floodplains. This included researching historical flooding data and current land-use plans, as well as gathering information from stakeholders and the public.
The team then formulated a floodplain management approach consisting of structural and non-structural alternative solutions to reduce or eliminate flooding hazards, which were further compared and evaluated to develop a set of preferred alternatives.
With the study complete, the District now has a comprehensive assessment of flood and erosion hazards. The strategies in the plan should reduce damages to property or loss of life from drainage issues and stormwater flooding.
This project is strongly supported by the Pima County Board of Supervisors, the City of Tucson and the Town of Sahuarita.
PROJECT UPDATE:
Since this study was conducted, the Lee Moore Basin Management Study was divided into two study areas that revised the floodplain, with Houghton Road as the dividing line between the two. The 2009 study established flow corridors that were agreed upon by multiple agencies and may be applicable for development projects. The
Lee Moore East and
Lee Moore West studies should be used for single-lot permitting.
