Clinton River Area of Concern Projects

Posted: 9/7/2016

Expiration date:


TO ALL INTERESTED AGENCIES, PUBLIC GROUPS, AND CITIZENS

The United States Army Corps of Engineers (USACE), on behalf of the United States Environmental Protection Agency (USEPA), is proposing an ecosystem restoration project at Galloway Creek in Rochester, Oakland County, Michigan (Attachment 1).  Galloway Creek is a tributary to the Clinton River and runs through the Katke Cousins Golf Course on the Oakland University campus.  Under the National Historic Preservation Act (NHPA) and the particular implementing regulation 36 CFR § 800.2(d)(2), it states that government agencies must provide the public with information about an undertaking and its effects on historic properties and seek public comment and input.  This notice provides the public with such information and seeks comment and input from the public. 

The purpose of the project is to restore floodplain connectivity, improve aquatic organism passage/movement, increase geomorphic stability, provide in-stream habitat, and increase wetland diversity and riparian habitat to contribute towards the removal of habitat-related beneficial use impairments in the Clinton River Area of Concern, which consists of the entire watershed.  The project will accomplish this by using natural channel design to restore a stable pattern, profile, and dimension to Galloway Creek and its associated floodplain.  A minimum of 3,000 feet of stream restoration and habitat enhancements will be designed over a 1.5 mile stretch of Galloway Creek based on the results of a geomorphic assessment, geotechnical investigation, site constraints, and stakeholder input.  Additionally, three of the golf course cart crossings will be improved to provide a bankfull width channel through the crossing and floodplain drainage (see Attachment 2, Photos 1, 2, and 3). 

The proposed project is composed of four reaches as described below and identified on Attachment 3.

•  Reach 1: The project will include the restoration of Reach 1 and the replacement of the under-sized culvert at the Hole 5 crossing with a 50 foot timber bridge.  The channel is constrained in the first 250 feet due to the sanitary sewer along the left bank.  The proposed channel will mostly follow the existing channel path, but there will be improvements to the pool spacing and radius of each bend.  The two hillslope failures along the right bank will be stabilized with toe wood and bankfull benches.  Existing clay tiles will be broken and riffles will be constructed to raise the groundwater table and provide floodplain connectivity. 

•  Reach 2: There is a lot of wood in the channel and the creek is over-widened in several areas.  Therefore, much of the channel will be re-meandered to the north away from the hillslope along the right bank.  The sections of abandoned channel will be intermittently plugged and will function as off-channel oxbow ponds.  Channel excavation is often less expensive than trying to narrow an incised channel and stabilizing the earthen fill.

•  Reach 3: The stone-faced concrete arch crossing will not be disturbed.  Several 18-inch diameter Corrugated Metal Pipe culverts will be installed at the bankfull elevation on one or both sides of the crossing to improve flood conveyance and reduce flow constriction.  The channel will mainly be re-meandered in the current alignment due to lateral utility constraints.  The gully draining the pond on the left bank will be filled.

•  Reach 4: The channel will be relocated to the south of the existing pipeline exposure. The pipe is deeper in the proposed channel location and the floodplain elevation is lower than the near bank area due to historic spoil berms.  This will increase the channel slope in the lowest gradient reach.  All pipe lowering and channel work in the gas pipeline right of way be constructed by the Consumers Energy contractor in winter 2016/2017 prior to restoration construction.

The USACE, on behalf of the USEPA, has determined the Area of Potential Effect (APE) (Attachment 3) for the project and has reviewed the proposed project under Section 106 of the NHPA.  The USACE has identified a National Register property, Meadow Brook Farms, which is located near the project area; however, the property is well outside the APE and will not be impacted by the proposed project (Attachment 3).  The USACE, on behalf of the USEPA, has reached a preliminary determination that the proposed project is an undertaking and that there would be “no historic properties affected” based on no historic properties being present in the project area. 

Any person who has a historical or cultural interest that may be affected by the proposed project described in this notice may submit comments regarding the effects determination.  The comments must be submitted in writing and must clearly state what historical or cultural interest may be affected by this activity.  Comments should be sent within thirty (30) days of the date of the public notice to: ATTN: CELRE-PLE (Charles A. Uhlarik), U.S. Army Corps of Engineers, Detroit District, 477 Michigan Avenue, Detroit, Michigan 48226-2550.  

All comments received will be reviewed by the USACE, on behalf of the USEPA, and will be given consideration in the preparation of the final project design.  The USACE may change the effects determination based on the comments received.  The USACE will also consult with the Michigan State Historic Preservation Office, on behalf of the USEPA, regarding this project before a final effects determination is made.  Upon reaching a final effects determination, documentation will be available for public inspection on the USACE website  prior to approving the undertaking.  If no comments are received by the end of the review period, it will be assumed that you have no comment.
