Alternative Parking Update
Wednesday, September 29, 2021

---

The City received a grant for the construction of a green parking lot (permeable pavers) at the Library Parking Lot (Central Lot) in the amount of $650,000  from the Metropolitan Water Reclamation District’s (MWRD) Green Infrastructure Program. This exciting and forward thinking reconstruction project begins Wednesday, September 29, 2021. The parking lot will be closed until mid-December. 

The contractor for the project is Copenhaver Construction, and the City’s on-site engineer is Hancock Engineering.

 This project includes complete excavation and removal of the existing pavement, and replacement with compacted stone and permeable brick pavers.  Water will drain though the permeable pavers into the stone layer below, where water will be stored until it infiltrates into the ground, or drains out slowly through a perforated pipe.  All of the parking islands will be replaced with native plantings and trees which will also facilitate the infiltration of water. Once completed, the new parking lot and islands will be able to hold over 192,000 gallons of water.  

A tentative schedule for the project is below:



The City is working hard to provide alternate parking locations and wayfinding signage to direct patrons where they can park.
