Easterly Creek is a tributary to Westerly Creek in the northwest area of town and Del Mar Parkway is currently aligned where the creek bed of Easterly Creek historically used to be. An Outfall Systems Plan (OSP) for Easterly Creek was completed in 2012 that identified several recommendations to help improve storm flows and water quality and reduce flooding in the area. The Havana Park detention pond was one of the projects identified. The Havana Park detention pond was originally constructed to store approximately 8 acre-feet of runoff. The pond is known to have overtopped several times at the north end, overflowing into East 11th Avenue flooding areas of town to the west. The bottom of the pond has silted in over the 50 plus years of its existence and the outlet works for the pond have severely deteriorated, as the invert of the 18-inch corrugated metal pipe (CMP) outlet pipe is completely corroded. The improvement plan identified re-grading the pond for increased storage volume and water quality volume and for modifications to the pond inlet for more efficient delivery of flows to the pond. Through design Aurora Water worked closely with PROS to ensure the existing park and playground equipment at this site were incorporated into the final design.
The City is planning to construct improvements to minimize flooding, to protect life and property and to improve water quality. Specifically, project construction includes: 10,400 cubic yards of earthwork, 460 feet of storm pipe ranging in size from 24 inch diameter to 54 inch diameter, 9 inlets, 10 manholes, concrete inlet and outlet structures, concrete forebay, 635 cubic yards of riprap, 156 feet of curb and gutter, 3 ADA curb ramps, 1100 feet of sidewalk, full depth asphalt, seeding, traffic control, erosion control and other miscellaneous items necessary to complete the work.
