Williams & Works staff provided surveying and engineering services for the re-platting of McElroy's addition of a 7-acre plat on the corner of Bank and Collins Streets in the City of Kalamazoo.

Efforts included coordinating with the City of Kalamazoo to develop several conceptual layouts for the proposed plat and creating the proposed typical section to be used for the new public street. The new road has an 80-foot right-of-way with a 20-foot-wide boulevard section where it connects to Bank Street. The road then transitions to a 66-foot right-of-way.

Property development required relocation of the 8-inch public sanitary sewer, a new 8-inch watermain, and storm drain piping for runoff. The storm drain piping was oversized to provide in-line detention in an effort to relieve burden on the existing storm drain system, which is now undersized due to the development over the years. Storm water from the development is treated using an Aqua-Swirl concentrator to remove sediment and debris from the system before discharge into nearby Portage Creek, a tributary of the Kalamazoo River.

Construction permits obtained for the project include those required by the Michigan Department of Environmental Quality for sanitary sewer and watermain. Additionally, a floodplain fill permit was required to construct the storm drain within the limits of the 100-year floodplain. The permit also allowed the finished grade elevation of two proposed lots to be raised to provide sufficient buildable area above the 100-year flood elevation.

Williams & Works is providing construction administration and inspection services throughout the course of the construction schedule to verify the installation of the sanitary sewer, storm drain, and all concrete work within the right-of-way.

The project was funded, in part, with Community Development Block Grant funds.
