Title
Consider a resolution authorizing the Mayor to execute an Interlocal Agreement with the Upper Brushy Creek Water Control Improvement District (WCID) for the construction and maintenance of storm water facilities regarding the Texas Avenue extension project.
Body
The Texas Avenue Connection will provide for a new roadway connection. The project will extend existing Texas Avenue from Greenhill Drive to its current termini, approximately 730ft. east of Greenhill Drive. The Texas Avenue Connection will provided continuity from Interstate 35 to the existing subdivisions east of Greenhill Drive. The project is proposed to be ready for advertising by mid-November 2017.
Additionally, Upper Brushy Creek Water Control and Improvement District(WCID) will be concurrently constructing a new facility on their recently purchased site, directly north of the Texas Ave. project. Both projects are required to treat, and detain, their respective storm water runoff. It is the intent of the City of Round Rock(CORR) to partner with WCID in its treatment and detention of storm water by way of a sedimentation/filtration/detention pond(Detention Pond). This partnership will be documented through the execution of an Interlocal Agreement(ILA) that will be mutually beneficial for both WCID and the CORR.
The ILA provides that the CORR will be responsible for costs associated with the design, construction and permitting of the required Detention Pond(assuming 75% impervious cover). The design and construction costs associated with the Detention Pond are for a standard typical Detention Pond; any requests to upgrade the facility, or reduce its footprint, will be the financial responsibility of WCID. Further, the ILA requires WCID to allocate the land prescribed for the Detention Pond at no cost to the CORR. Additionally, WCID will be solely responsible for all costs associated with the maintenance and repair of the Detention Pond indefinitely.
