CITY OF IMLAY CITY
FINAL NOTICE AND PUBLIC EXPLANATION OF PROPOSED ACTIVITY IN A 100-YEAR FLOODPLAIN AND/OR WETLAND
To: All interested Agencies Groups and Individuals
This is to give notice that the City of Imlay City has conducted an evaluation as required by Executive Order 11988, in accordance with HUD regulations at 24 CFR 55.20 Subpart C Procedures for Making Determinations on Floodplain Management, to determine the potential affect that its activity in the floodplain and wetland will have on the human environment.
The City intends to replace storm sewer, sanitary sewer, and water main in an older part of the City along Fourth Street from Main Street to M-53. The City will replace the 1950 ‘s cast iron water main and services from Main Street to White Street. Storm sewer and sanitary sewer that has exceeded useful life expectancy and are failing will be replaced as from Main Street to M-53. New sanitary sewer will be installed from along M-53 from Fourth Street to Third Street, with a bore across M-53 to the east to tie into an existing, larger interceptor sewer. The new sanitary sewer will serve 3 new parcels that currently have septic systems and are not served by sanitary sewer. The existing sanitary sewer under M-53 will be abandoned in-place, including the aging and failing corrugated metal sanitary pipe that crosses underneath the CN Rail Bridge.
The City will rehabilitate approximately 710 linear feet of existing sanitary sewer and six sanitary manholes by installing Cured-In-Place-Pipe and multilayer polyurea manhole liner. This project will extend the useful life of the existing sanitary sewer without causing a disturbance to M-53 traffic. This section of sewer is directly upstream of the Wastewater Treatment Plant and is noted as critical condition during the SAW Grant/Capital improvement Plan.
The existing Newark Road Pump Station is located at the southeast corner of Newark Road and S. Almont Ave. in the City of Imlay City. It was installed in 1988 and collects sanitary sewer flow from a service area which can be generally described as S. Almont Drive, 600 feet north and 1,800 feet south of Newark Road, and the commercial shopping center to the south of Newark Road. The station is a submersible pump station, equipped with duplex submersible pumps, a 10-foot diameter concrete wet well, and an adjacent valve vault. The existing pumps are equipped with 3 HP motors, and are each rated for 50 gpm at 20 feet of total dynamic head. The Newark Road Pump Station’s pumps, valves, and controls are nearing the end of their useful life and are in need of replacement. The pumps have been known to clog with rags and there have been instances where the forcemain has required cleaning to remove grease out of the line. Additionally, the control panel and controls are antiquated and are in need of upgrades. Therefore, the City has chosen to rehabilitate the pump station with new pumps, valves, piping, and controls to provide continued, reliable service to the customers in the surrounding area. Approximately 0.1 acres of work will be conducted within floodplains. The proposed project is located 205 S Cedar St and along existing roads in the City of Imlay City, Lapeer County.
The City of Imlay City has evaluated the alternatives to building in the floodplain/wetland and has determined that it has no practicable alternative. Environmental files that document compliance with Executive Order 11988, are available for public inspection, review and copying upon request at the times and location delineated in the last paragraph of this notice for receipt of comments.
This activity will have no significant impact on the environment for the following reasons: Proposed work is to take place in existing disturbed locations and will not impede flow of any waters within the floodplain.
The City of Imlay City will undertake the following mitigation measures to minimize adverse impacts and to restore and preserve natural and beneficial values: Work will take place with appropriate silt fencing where needed and restoration of the landscape will take place. This project will fully comply with state and local floodplain protection procedures.
