Alamo Wash Basin Management Study Project Update – September 2018
FLOOD CONTROLFLOOD CONTROL
Project Location
The Pima County Regional Flood Control District (District) has begun work on the Alamo Wash Basin Management Study (Study). The Study area encompasses about 9.5 square miles within the City of Tucson and includes the Alamo, Arcadia, Van Buren and Sahuara washes.
Project Description
The purpose of the Study is to identify flood-hazard areas and drainage problems in order to develop a comprehensive flood-control plan (Plan) that provides cost-effective solutions to alleviate and/or manage flooding within the Study area. The goal of the Plan is to develop strategies that reduce flooding, improve public safety and provide a balanced multi-objective approach to managing the watersheds, floodplains and resources in a fiscally responsible way. In addition, the Plan will provide guidance for development, redevelopment and retrofits in flood-prone areas and drainage alternatives to further limit the potential for flooding. Finally, the Plan will ensure that the floodplain management regulations will balance potential competing interests in the community.
Project Outreach
This website was created for this study and contains project details including status.
• A public sector stakeholders meeting was held Friday, Feb. 10, 2017.
• The District hosted two open house meetings to solicit additional input from the public. Those open house events were held on Mar. 22, 2017, at Sky Islands Public High School (6000 E. 14th St.) and Oct. 23, 2017, at Dodge Traditional Magnet School (5831 E. Pima St.). A third and final Open House will be held in late 2018.
• The District has submitted revised regulatory discharge values to the Federal Emergency Management Agency (FEMA) for review and approval. Those discharge values are to be used in the alternatives analysis.
