Chestnut St. to Garden Dr. Drainage Improvements
Project Overview and History
The Chestnut Street to Garden Drive Drainage Improvements project is phase two of the overall Chestnut Street to Eastman Park Drive Drainage Improvements project. The Chestnut St. to Eastman Park Dr. Drainage Improvement Project is an effort to mitigate flood concerns in an area generally located west of CO 257, south of Chestnut St., north of Eastman Park Dr., and east of Columbine Dr. The project will also reduce flooding along Chimney Park Dr. from Walnut Street to the municipal swimming pool. Flood risk is expected to be lowered to less than 1 percent annual flood risk (100 yr flooding) for 56 residential structures that currently have moderate to high risk of flooding. Street flooding risk will also be reduced for a number of streets located in the described benefit area.
Phase one of the project included storm line improvements on First St., Garden Dr. and expansion of the Folkstone Detention Pond, which was completed in 2020. Work will include the construction of infrastructure designed to collect stormwater along Chimney Park Drive, Chestnut St. and Garden Dr., and route it to the recently expanded Folkstone Detention Pond. Improvements will also be constructed at Chimney Park Detention Pond which will result in flood reduction along Chimney Park Drive. The goal of this project is to reroute flood potential away from homes and streets.
General Project Timeline
Though roadway impacts are not anticipated to start until early March, erosion control measures and drainage pipe staging are anticipated to begin in December.
On Monday, December 4, contractors will begin erosion control at the CARE housing facilities located off of Garden Dr. in between Columbine Dr. and Cornerstone Dr. Erosion mitigation measures include installing straw logs and similar devices and implementing other techniques to prevent disturbed soil from washing away from the job site.
As work continues into 2024, Chestnut St. and Garden Dr. are anticipated to start being impacted in January. During that time, drainage pipes that will be placed in the spring will start to be staged in and around the construction zone. Throughout the duration of the project, residents will still have access to homes and driveways, but may experience some delays or have to detour.
Public Information Sessions
Information sessions for the general public were hosted on Monday, September 5 and on Tuesday, November 28 via Zoom to give residents impacted by the work the opportunity to learn more about the project and ask questions. The recording for the info sessions can be viewed below.
