Centennial Acres
Promoting Conservation Landscaping in Residential Areas

Project Location - Keystone Drive and Patton Road, Lower Paxton Township
Existing Conditions - By early 2000, the percentage
of developed lands in the watershed almost doubled in less than 10 years. At this rate of development,
absorbing and filtering runoff from lawns and open spaces is necessary for protecting the stream from soil erosion and nutrient runoff.

The creek travels through portions of more than 50 properties in Centennial Acres. The stream has minimal riparian vegetation and suffers from bank erosion and nutrient and sediment deposition.
 

Project Overview - The Centennial Acres project involves restoring more than five acres of riparian corridor in a residential area, using conservation landscaping techniques. As part of the management portion of the study, the project will result in options/incentives for applying similar stormwater management projects to other residential neighborhoods. The project will raise public awareness about the importance of stormwater management, and what the individual homeowner can do to mitigate impacts from their properties.

Project Activities - SRBC is recruiting volunteer households from the Centennial Acres community to participate in activities such as keeping roof runoff on-site, reducing fertilizer use, reducing mowing frequency, and enhancing stream buffers.

Volunteer households will be provided the services of a Pennsylvania-licensed landscape architect, and all of the labor, plants, and additional materials needed to implement conservation landscaping techniques to manage stormwater runoff on-site.

This pilot-scale residential retrofit program, that can be applied to similar residential developments watershed-wide, is intended to lessen the impact of stormwater runoff and improve water quality by re-establishing a forested riparian buffer.
