SUBJECT:2023/24 STORMWATER EROSION CONTROL PROGRAM (INIS GROVE)
COUNCIL ACTION FORM
BACKGROUND:
The Stormwater Erosion Control Program is an annual program for the stabilization of areas
that have become eroded in streams, channels, swales, gullies, or drainage ways that are part
of the City’s stormwater system.
This project involves the stabilization of the ravine within Inis Grove Park, directly north
of the Miracle League Park and Playground. The project is planned for construction over a
single year and in one stage. The construction will allow uninterrupted access to the Inis Grove
Park and will include fencing to keep children and other park users out of the construction
area. The project will replace sections of storm sewer pipe, as well as armoring of the ravine
to heavily reduce erosion in the area. Plans and specifications for this project were completed
by WHKS.
This program also includes a project along College Creek, which was completed and accepted
by City Council on October 14, 2025.
On February 18, 2026, bids for the Inis Grove project were received as follows:
