Normandy Subdivision Detention Basin Conversion

Current Status (May 11, 2016)


The basin was seeded on last fall on November 11, 2015 and certain areas blanketed. Seed takes a while to germinate and you shouldn’t expect to see the seed mix bloom until mid-late June, creating the naturalized habitat. In addition, there may be some oats in May.   


Status for week of 
November 11, 2015

The second herbicide application was applied the week of 11/2.  The basin was seeded on November 11, 2015 and blanketed.  The initial herbicide treatment was applied the week of Oct 12, 2015 within limits of conversion.

The grass will eventually die off from the herbicide applications and the grass will remain on-site and act as mulch for the seed mix.  Next spring the seeds will bloom and create the naturalized habitat.   City will continue maintenance in the spring, including herbicide, and the City work with the contractor to ensure a full coverage from the fall seeding.  

Project Purpose


The City of Batavia will be working with a Design Build contractor that will work with the City of Batavia to convert an existing dry detention basin in the Normandy Subdivision located at the northeast corner of Raddant Road and Edwards Drive to a naturalized basin. The original basin was constructed in the late 1990’s. The conversion of the basin will include native plants. To see a local naturalized basin in town that was just reconstructed go to the Windmill Lakes Detention Basin behind Tower Car Wash and Holy Cross Church west of Randall Road on the south side of Main Street. 

Project Background


The City awarded the bid on September 22, 2015 to Tallgrass Restoration.  Construction started shortly thereafter. The contractor has created a seed design mix for with native plants that will showcase color while keeping the plants fairly short in height. The mix will include sedge, bluegrass, iris, coneflower, milkweed, aster, goldenrod and black eyed susan.
