2019-177 Choctaw Area Storm DrainDate: September 27, 2019 Report No. 2019-177
INFORMAL STAFF REPORT TO MAYOR AND CITY COUNCIL SUBJECT: Choctaw Area Storm Drain Improvements Status Update BACKGROUND: The Choctaw Drainage project is in the Sequoia Park Subdivision, a neighborhood southeast of the intersection of University Blvd. with Ruddell St. This project was identified within the last few years (see attached conceptual map) based on citizen concerns. The project was slated for a study and possible design pending higher priority projects and available resources. The Sequoia
Park Subdivision is not located in a FEMA designated floodplain; however, flows are introduced to the neighborhood from developments to the North and West. The Choctaw Area Storm Drain Improvement Study is being performed by Staff and is early in the analysis and conceptual design phase with completion slated for middle to late October.
DISCUSSION: This ISR is an update of the analysis of Choctaw Area Storm Drain Improvements project. The Choctaw drainage improvements will convey water from: • Subdivisions North of University
Conveyed through box culverts under University and associated storm drains This is the beginning of the natural channel – See attached photos. • Sequoia Village Apartments detention basin • Sequoia Park Apartments detention basin (open space) • Local Street Drainage (Sequoia Park Subdivision)
During the June 4 City Council meeting, Councilmember Armintor requested that changes to natural storm water channels will be brought before the Committee on the Environment. In response to this request, staff will bring future changes to natural storm water channels before City Council for review.
CONCLUSION: Staff will present an updated ISR and cost estimate based on the outcome of the study in October and request direction from the Council. If a material change of the channel is warranted by the study, this project will be presented to the Committee on the Environment.
