Subject: Request for information about proposed Federal Emergency Management Agency (FEMA) project; Pre-Disaster Mitigation Competitive (PDM-C) Program, in the Town of Blackrock, Seneca County, State

Dear Name:

The City of Blackrock has applied to the FEMA for a grant under FEMA’s Pre-Disaster Mitigation-Competitive (PDM-C) program. PDM-C grants provide funding for measures designed to reduce or eliminate future disaster damage and disaster relief expenditures. The Town of Blackrock proposes to make stream improvements including channel straightening and stream bank armoring along Seneca Creek to alleviate flooding damage to Blackrock Road and the bridge over Seneca Creek. The project area is located next to Blackrock Road where it crosses Seneca Creek (see attached map).

One of the requirements for the FEMA PDM-C application is to identify the presence of any regulated resources in the project area, or any permitting requirements that may be involved. At this time, the city of Blackrock would like to inquire about resources regulated under the Clean Water Act, the Rivers and Harbors Act, Executive Order 11990, Protection of Wetlands, and Executive Order 11988, Floodplain Management.

Attached to this correspondence is a United States Geological Survey (USGS) map indicating the project area, pictures showing the project site and the nearby environment, a narrative describing the proposed scope of work, a Hydrology and Hydraulics study of the proposed action, and site drawings showing the extent of the project activities.

The proposed project involves straightening about 800 linear feet (lf) of the channel of Seneca Creek west of the bridge over Seneca Creek. This would require excavating the existing bank between 0 and 30 feet to the south to allow the stream to follow a straighter path. The excavated bank would be lined with rip-rap to protect it from future erosion. The second element of the project is upstream of the bridge over Seneca Creek, and involves the placement of rip-rap armor on about 400 lf of the north side of the stream (see photos).

Your assistance in this matter is greatly appreciated. If you have any questions regarding this project, please contact me by phone (xxx) xxx-xxxx, fax (xxx) xxx-xxxx, by email (, or by letter at the letterhead address.
