City Council Regular Meeting

Meeting Date:

09/08/2020

BACKGROUND

Over time, Colony Drive, Castle Hills and Osage Avenue drainage channels have accumulated excess silt, as well as have experienced some erosion caused by historical water flows. To improve the performance of the channels and allow them to accommodate adequate water flows, staff intends to de-silt and install rip rap, concrete, and hydro turf as appropriate. This is shown in the bid document highlighted in green. Schertz received five bid proposals to perform this work and C-3 Environmental provided the lowest qualified bid of $378,425.15. The project total request is for $416,267.68 which includes a 10% contingency. These drainage projects are funded in the FY 19-20 budget and part of the Drainage Capital Improvement Plan.

GOAL

Approve Resolution 20-R-99 to provide funding for necessary drainage maintenance and improvements in the Colony Drive, Castle Hills and Osage Avenue drainage channels to include de-silting and the installation of rip rap, concrete, and hydro turf.

COMMUNITY BENEFIT

These drainage maintenance and improvement projects will allow the drainage channels to accept water flows and direct those flows away from structures, private property, roadways, etc. The rip rap and concrete will decrease the amount of future maintenance and the hydro turf will help protect the channel from future erosion while being aesthetically pleasing.

SUMMARY OF RECOMMENDED ACTION

Staff recommends council approve Resolution 20-R-99

FISCAL IMPACT

The projects are funded in the approved FY 19-20 budget.
