    NEED AND PURPOSE STATEMENT

    Newton County and the City of Covington, county seat, are involved in a number of progressive projects associated with their 2050 Build-Out Plan a plan aimed to create a sustainable future for the county and their resources.

    The County is involved in the Atlanta Regional Commission (ARC) and became a member of the Livable Communities Initiative (LCI) in 2005. My project falls under the Covington US 278 Corridor LCI Study Area. The LCI program is intended to promote greater livability, mobility and development alternatives in existing corridors, employment centers, and town centers. The rationale behind the program is that directing development towards areas with existing infrastructure will benefit the region and minimize sprawling land use patterns. Minimizing sprawl, in turn, will potentially reduce the amount of vehicle miles traveled and the air pollution associated with those miles. Finally, the LCI program is using the successful 1996 Olympics model to promote the concept that investment in public infrastructure will spur private investment. Thus, the LCI program is a vehicle whereby the ARC can attempt to direct mixed-use and mixed-income development towards existing infrastructure by providing study and implementation dollars.

    The UGA Metropolitan Design Studio of 2007 completed the Pace Street Corridor Study which Tunnell-Spangler-Walsh (TSW) in Atlanta, GA expanded on in their Pace Street Corridor Scoping Report. The city has received funding for further study and development. As part of the initial project, the studio and TSW indicated that a potential greenway could tie into the redeveloped Pace Street where it crosses Dried Indian Creek. To receive further funding, the ARC requires more detailed plans for how and where the Greenway will connect.

    DESCRIPTION OF PROPOSED PROJECT

    My senior project for the Dried Indian Creek Greenway and Stream Restoration consists of two parts. The main focus will be on the length of Dried Indian Creek between US Hwy. 278 to the north; and, Washington St. to the South as the greenway trail within the 25 buffer along the creek. The intent of the greenway is to create a recreational and educational opportunity while increasing pedestrian connectivity. Without an aesthetically pleasing creek, which inherently will be more ecologically sound, the greenway will fail to be popular. The second part will be a series of suggestions for remediation of stream conditions, primarily, north of Hwy. 278, adjacent to the Kroger shopping center. Due to the urban nature of the stream, a total restoration is not likely to be conducted in all parts of the stream basin. Stabilization to prevent further erosion will be instituted in areas deemed appropriate.

    ANIMAS RIVER TRAIL - DURANGO, CO

    Animas River Trail has approximately 7 miles of hard-surface trail running through town along the Animas River with 2.5 additional miles planned for the future. It travels through twelve city parks and across five bridges. Construction of the trail system has spanned several decades starting in the 1970s. Extension of the trail northward past city limits has been in planning for nearly a decade but several public meetings to move the process forward have been held since 2008.

    ROCKY BRANCH RESTORATION - NC STATE UNIVERSITY, DURHAM, NC

    Rocky Branch is an urban creek that runs more than a mile through the heart of NC State University campus. The stream was narrow, deep, suffering from severe erosion and is an unsafe eyesore on campus. A three-phase stream restoration, greenway, and 6000 trail plan is underway with the first two phases already completed. The restoration strives to stabilize the creek; improve water quality, aquatic and wildlife habitat; and integrate the creek into the campus environment.
