Browse Search

Three alternatives were drafted which included a project area of approximately 164 acres of land divided into proposed land uses based on the project area's environmental conditions, elements of the 2002 Chapel Hill Resolution, Rogers Road Task Force report, Mapping Our Community's Future report, and local government leaders' objectives for the Greene Tract. Alternatives must provide three levels of development and incorporate: – School site – Recreational facility site – Park space – Natural preservation areas – Development – Road network and infrastructure – Environmental buffers – Cultural areas of significance Additional consideration will be required for several elements of the Greene Tract: – Roadway design – Site infrastructure (i.e. water, sewer, fiber) – Open space, recreational facility, and tree canopy preserva- tion – Environmental (i.e. wetlands, streams, buffers, stormwater regulations) – Low Impact Development – Cultural and historical features – Density, land use, and zoning regulations – Transit • Further evaluation will impact and alter the proposed alternatives in the future • Site plan review process will address additional land use issues and help shape the plan for the Greene Tract Land Use Categories Proposed Joint Owned Preserve: Includes areas of existing wetlands and streams located on the Greene Tract. Wetland and stream information is based on information collected from Town of Chapel Hill, Town of Carrboro, and Orange County staff. Buffer standards were determined based on a review of the Towns' and County's standards and utilizing the most restrictive. Additional analysis and delineation will be required moving forward. These areas would not be developed, but will remain as natural preserve areas in the future. Additional Preserve: Includes areas for future preservation and upland hardwood forest which are not contained in the required preserve areas. In addition to the acreage proposed to be preserved, approximately 10 – 20% of the acreage pro- posed for development will be utilized for open space to provide areas of on -site preserve and connections to other areas of offsite preserve. Proposed Headwaters Preserve (County Owned): Includes the original 60 acres designated for preservation by the Towns and County. Elementary School Site: Includes acreages allocated for a future elementary school site. The proposed school site has been relocated to the southern portion of the site due to environmental constraints and is not included as part of the original 18 acres designated for development in the Rogers Road Task Force Report. Chapel Hill — Carrboro City Schools staff has re- viewed the proposed alternatives and provides support for the proposed location. Recreational Facility Site: The proposed recreational facility site is also located on the southern portion of the Greene Tract in order to provide access to the future elementary school students. Chapel Hill — Carrboro City Schools staff provides sup- port for the proposed recreational facility site, which could also support community usage. Development: Includes areas proposed for development in the short term. The location for this category was determined based on site elevations and proximity to existing infrastructure. In addition, the proposed location for development in- cludes the original 18 acres identified for affordable housing in the Rogers Road Task Force Report. Includes possible loca- tions for on -site stormwater facilities. Road: The preliminary roadway design was based on existing environmental concerns and elevations contained on site. The proposed alternatives recognize a need for additional roadway connections in the future. Land Banking: Includes areas without environmental concerns and access to infrastructure which may provide an oppor- tunity for future development. These areas will remain undeveloped in the short term, but may be evaluated for develop- ment (i.e. residential, commercial, health services, and /or park /recreational facility) in the long term (5 -10 years) depend- ing on the needs of the community and planning partners at that time.
