PURPOSE
The purpose of this Intergovernmental Agreement (IGA) is to partner with Urban Drainage and Flood Control District to perform maintenance of the City of Brighton South Drainage Outfall. Through the conditions of the IGA, Urban Drainage and Flood Control District will provide Twenty-Five Thousand dollars ($25,000) and the City will provide Seven Thousand Five Hundred dollars ($7,500) to perform the maintenance.
BACKGROUND
Stormwater runoff from the major Prairie Center Development and other locations in the City is carried to the South Platte River through the City’s South Drainage Outfall. The culvert under Sable Boulevard has become silted in and caused silt deposition on a concrete trickle channel in the South Drainage Outfall. The accumulation of silt does not allow for the passage of stormwater back to the South Platter River as designed. Maintenance is needed to remove the sediment from the culvert and the concrete trickle channel.
Urban Drainage and Flood Control District provides funding to local jurisdiction through its annual Work Maintenance Program. The City of Brighton has asked for assistance from Urban Drainage and Flood Control District to fund this maintenance project.
CRITERIA BY WHICH COUNCIL MUST CONSIDER THE ITEM
FINANCIAL IMPACT
Seven Thousand Five Hundred dollars ($7,500) is budgeted in the Water Activity Enterprise fund to provide a percentage of local funding to Urban Drainage and Flood Control District for the South Drainage Outfall maintenance project. City Council has previously approved funding for the project in the 2017 Budget. The City of Brighton will provide 23.08% and Urban Drainage and Flood Control District will provide 76.92% of funding for this maintenance project. There is no requirement for reimbursement to the District.
STAFF RECOMMENDATION
Staff recommends participation in the IGA titled MAINTENANCE OF DRAINAGE AND FLOOD CONTROL IMPROVEMENTS FOR BRIGHTON SOUTH OUTFALL AT 27TH AVENUE TO SOUTH PLATTE RIVER (Agreement No. 17-02.01) to remove silt from the drainage way and return the South Drainage Outfall back to original design capacity. The project will improve the quality of water being discharged to the South Platte River and will reduce the possibility of flooding.
