Summit Boulevard - Spanish Trail to Firestone Boulevard Stormwater Treatment Enhancement

Spanish Trail has experienced issues with stormwater stacking in the road and creating a hazard driving condition. This is due to the existing stormwater conveyance system being undersized for its contributing basin’s flow. This project will serve to increase the flow capacity of the conveyance system by enlarging curb inlet top and installing a new Stormwater outfall into the Fire Station 3 pit. The focus of the project is twofold. First, to provide additional conveyance capacity for an overtaxed system. Second, if the bid alternate comes in at an affordable price, to provide stormwater treatment for a currently untreated drainage sub-basin. This treatment will be provided by installation of bioretention cells to collect water from the roadway. This project is consistent with current technology for stormwater retrofit treatment and is part of an ongoing program utilized throughout the City to improve water quality of area waterways. As a result of these improvements, work site safety, MOT, maintenance/bypass of stormwater flow, and erosion control will be paramount issues. General work to be accomplished will include installation of new inlet tops, cut and patch of pavement, storm structures, new storm pipe, and sod. The LS Maintenance of Traffic item shall include all signs, devices and other cost associated with maintaining traffic during the project. No night work shall be permitted on this job.
