Notice of Availability: Draft Environmental Assessment for Indian Rock Dam/Codorus Creek Flood Risk Management Project, York County, Pennsylvania

Published Aug. 29, 2018
Expiration date: 10/1/2018

ALL INTERESTED PARTIES: In accordance with the National Environmental Policy Act (NEPA) of 1969, as amended, the U.S. Army Corps of Engineers, Baltimore District, (USACE) has prepared a draft Environmental Assessment (EA) to assess impacts for repairs to the Codorus Creek Flood Risk Management (FRM) component of the overall Indian Rock Dam/Codorus Creek FRM Project on Codorus Creek. USACE-Baltimore operates and maintains the Codorus Creek FRM project, which was constructed in the 1930s and operational in the 1940s. The Codorus Creek FRM project passes through West Manchester Township, Spring Garden Township, York City, North York Borough, and Springettsbury Township, all located in York County, Pennsylvania. The Codorus Creek FRM project is approximately 4.8 miles in length, and includes a widened and deepened creek channel, levees, floodwalls, and bank protective works. The project’s infrastructure is aging and in need of repairs to ensure it continues to properly perform its FRM functions. At this time, rehabilitation of floodwall, levee, drainage structures, and bank protective works are anticipated.

The draft EA has been prepared for the actions relating to the construction and rehabilitation of Codorus Creek FRM project. Potential impacts were assessed with regard to aquatic ecosystem impacts; temporary construction impacts to water, air and traffic; endangered and threatened species; hazardous, toxic and radioactive substances; flooding; cultural resources; and the general needs and welfare of the public.

Any person who has an interest in the project may make comments and/or request a public hearing within 30 days of the date of publication of this notice. Comments must clearly set forth the interest that may be adversely affected by this proposed action and the manner in which the interest may be adversely affected. Written comments received on or before this date will become part of the written record and will be considered in the determination of impacts to the environment. A Finding of No Significant Impact is anticipated to be signed upon review of comments received and resolution of objections, if any.
