6. Public Hearing, held before the Town Council, at the next available public hearing scheduled <br />for Special Use Permit applications; <br />7. Town Manager's Report to Council, completed within 30 days of the public hearing; and <br />8. Council Action to approve, approve with conditions, or deny the application. <br />The Neville tract has an existing Special Use Permit for extraction of earth materials. The landscape <br />buffer yards established in the Permit that are applicable to the neighboring residential properties are <br />100 feet in width. Landfills are not permitted in the R -1 zoning district, which is the current zoning <br />designation of the Neville tract. Therefore, the property would need to be rezoned to the RT zoning <br />designation, which does permit landfill development with a Special Use Permit. Following rezoning, <br />the existing Special Use Permit could be amended to allow for development of any of the solid waste <br />management facilities discussed herein. <br />Chapel Hill's Development Ordinance would apply to the site. The Ordinance includes a restriction <br />on building size and height in the RT zoning district. A proposed transfer facility or MRF on the <br />Neville tract would be larger than the allowable building size based on the floor -area ratio for the <br />RT zoning district and the acreage of the Neville tract alone. However, a larger building would be <br />permissible if the floor -area ratio were increased in a modification to the existing Special Use <br />Permit, or if the Neville and Greene tracts were combined into one tract by modifying the deed <br />descriptions. <br />A maximum building height restriction of 35 feet exists within the RT zoning district. Discussions <br />with the Chapel Hill Planning Department indicate that the zoning restrictions do not impose a <br />height limitation on a landfill, but a height restriction could be stipulated in the Special Use Permit. <br />4.0 SITE MONITORING REQUIREMENTS <br />A ridge line runs east -west across the site and divides the property almost in half. The topography <br />ranges from approximately 575 feet (MSL) along a ridge top near the east central portion of the <br />property, to approximately 550 feet (MSL) in the northwest and southwest corners. Surface drainage <br />and assumed groundwater flow is primarily to the north in the northern half of the property, and to <br />the south in the southern half, towards wet weather drainage features that exit the site in the <br />northwest and southwest comers. There is also a smaller component of flow towards the west along <br />the ridge line. An inferred potentiometric surface map is included on Drawing No. 1. <br />Seven soil test borings were performed on the Greene tract in 1982, primarily along the topographic <br />highs. The depth to bedrock, assumed from the auger refusal depths, ranged between 16.7 and <br />greater than 51 feet. The bedrock surface appears to be erratic based on the differences observed in <br />the site borings (see Table 1). Groundwater was encountered in two borings at depths of 20.9 and <br />32 feet below the ground surface.
