The proposal would require major subdivisions of property to follow either the current process, a Planned Development process or a Class A Special Use Permit process depending upon the location and number of lots. These Growth Management Amendments were discussed at the August 6, 2003 Planning Board Meeting. BACKGROUND: On May 6, 2002, the Orange County Planning Board forwarded a letter to the Board of County Commissioners regarding the need for additional growth controls in large residential developments. During a joint BOCC/Planning Board meeting on June 6, 2002, there was additional discussion of some of the challenges of large developments. On June 18th, the BOCC passed a resolution requesting that relevant issues and possible actions be researched prior to further deliberation. A brief discussion at the August 29, 2002 work session laid the groundwork for the September 3, 2002 BOCC meeting where an issues report was presented by the Planning Director, County Manager and County Attorney. A copy of that report is attached. After the presentation, the Board directed the Administration to prepare a Special Use Permit approval process for large-scale residential development projects. These amendments are the result of that directive. The discussion of managing growth and development led to two primary issues; What was the scale of the project? (i.e. how many lots), and Where is the project being proposed? These facets of proposals recognize that certain areas are more conducive to growth (i.e. where public services are efficiently provided in an urban or urbanizing setting) and other more rural areas that are constrained by the environment and land holding capacity and where larger scale projects are incompatible with the rural setting. These proposed special use subdivision regulations put forth growth controls that manage the size and location of projects as well as develop additional land development performance standards depending on the scale of the project. In essence, the larger the project, the more complex research and analysis are necessary to ameliorate the potential impact of the project. The proposal divides the subdivision approval process into five main categories depending on the location and the number of lots proposed. 1) August 2003 proposal -- For 6-19 lots in all zoning districts (same subdivision process that is currently in effect) 2) Proposed Class A Special Use Permit process -For 20-40 lots [Rural Buffer, Agricultural Residential, and R1 (Outside of Primary Service Area of Water and Sewer Boundary Agreement)] See Green Rural Area on Map 3) Proposed Class A Special Use Permit process -For 20-40 lots [R-1 and EDD (Inside of Primary Service Area of Water and Sewer Boundary Agreement) Level I Analysis] See Tan Urbanizing Area on Map 4) Proposed Class A Special Use Permit process -For 41-79 lots [R-1 and EDD (Inside of Primary Service Area of Water and Sewer Boundary Agreement) Level II Analysis See Tan Urbanizing Area on Map 5) Proposed Planned Development (i.e. Legislative Rezoning with Quasi-judicial Special Use Permit, Class A). This option is available to any property owner, who believes, by merits of the project design, that a justification to rezone the property can be made. Any project above 40 lots in a `green' Rural Area (see map) and above 79 lots in a `tan' Urbanizing Area would have the option to pursue rezoning. Rezoning would not necessarily, and in most cases would not, include any change in land use density. Projects would normally be filed for planned development in the rural areas based on design (reduction in lot size, type of units, etc.) and whether or not the project as proposed by the developer advances the County's goals in housing related areas. There are currently no projects `in the pipeline' (i.e. at Preliminary Plan submittal stage) that would be required to follow either of the proposed processes. Additionally, no project has been submitted for concept approval that would be required, by these proposed amendments, to follow either process. The attached amendments should be reviewed by the Board members prior to the August 25, 2003 public hearing so that pertinent questions may be asked and reflected in the official minutes of the meeting. This will allow staff to perform research prior to the return of the amendments to the Planning Board for a recommendation back to the BOCC. Subdivision Regulation Chanqes: A. Sets the new criteria for determining whether a proposed Preliminary subdivision is to be processed as a Planned Development or a Major Subdivision Class A Special Use or under existing ordinance provisions. The determining factors are location (whether inside or outside of Primary Service Area of Water and Sewer Boundary Agreement) and the number of lots proposed. Zoning Ordinance Changes A. Amends the Permitted Use Table by adding new uses to be identified as either a Planned Development or Major Subdivision Class A Special Uses under both the H and S categories B. Amends Table of Contents Article VIII to create a new Special Use identified as 8.8.29 with corresponding subheadings and nomenclature identified in the proposed amendment C. New Special Use Permit performance criteria 1. Professionally prepared Groundwater Yield Analysis for lots proposed on wells. 2. Certification from the respective governing body that controls access to public water and public sewer connections that adequate service provision availability is in place. 3. In designated Transition Areas, plans for sidewalks or pedestrian/bike lanes as part of the public road design guidelines. 4. Requires a Resources Management Plan that shows a location within subdivision for solid waste convenience center to serve the subdivision and where appropriate the general area where the subdivision is located. 5. Requirement to demonstrate Open Space connectivity and accessibility to all lots in the subdivision and the concept of `borrowed open space' for all lots in the subdivision. 6. Written and graphic site analysis showing soils, depth to water table, slope, hydrology, vegetation, natural areas and habitats of special concern, historic sites, etc. and an analysis of views into and from the site. 7. Requires a biological inventory that identifies habitat diversity, species diversity, and species of special concern such as those designated as threatened or endangered. 8. Protection of Existing Vegetation 9. Storm Water Management Enhancement 10. Mitigation Plan requirement when proposal to disturb environmentally sensitive areas as identified in the biological inventory. 11. Requires water conservation that indicates how irrigation systems for both the common ownership lands and individual lots adhere to conservation principles. 12. Requires use of xeriscaping principles. 13. Requires that Public Road Access be in accordance with a consistent, County-adopted public road access management plan. 14. Reserves a section to insert afuture-adopted regulation concerning `Crime Prevention through Environmental Design. 15. Requires Maintenance of Improvements as set forth in the Resources Management Plan. Process 1) Public Hearing to be held on August 25, 2003. 2) Planning Board to make recommendation to BOCC. 3) BOCC makes final decision. FINANCIAL IMPACT: There is no public financial impact associated with this item. RECOMMENDATION(S): The Administration recommends that the Board review the proposed amendments and provide feedback to staff in preparation for the August 25, 2003 public hearing. For the August 25, 2003 meeting: Planning Staff recommends Approval of the amendments. Administration recommends that the proposed amendments be referred to the Planning Board for a recommendation returned to the BOCC no sooner Phan November 19, 2003. 4 ORANGE COUNTY PLANNING DEPARTMENT 306F REVERE ROAD HILLSBOROUGH, NORTH CAROLINA 27278 c'°°{r o~ P y` 1 {7 5?

The proposed System promotes subdivision design at scales consistent with a rural/agricultural character or urban character depending upon geographic location within the County. 6 ORANGE COUNTY PLANNING DEPARTMENT 306F REVERE ROAD HILLSBOROUGH, NORTH CAROLINA 27278 ~.. b''A• TABLE, GROWTH MANAGEMENT SYSTEM URBANIZING AREA: Zoning R-1 AND EDD ZONING LOCATED IN PRIMARY SERVICE AREA OF WATER AND SEWER District: BOUNDARY AGREEMENT TAN* SUBDIVISION MAJOR CLASS A SPECIAL USE PERMIT PLANNED DEVELOPMENT 1.
