16 No further comment necessary, the applicant concurs with the responses providing by the Planning Staff and is of the opinion that the initial comment has been adequately addressed Additionally, please find attached as"Attachment V", additional documentation from Mi. Tom Konsler regarding the local geography, ground water and the use of Geo-thermal wells. • A Planning Board member asked how much draw (i.e. gallons per unit per minute during peak usage) the proposed community well would have and what potential impact there would be on adjacent property owners. Staff Comment: The applicant indicated they did not have recharge rate data or peak usage data available but would work to formulate a response. The applicant indicated he recently had spoken with Mr. Tom Konsler of Orange County Environmental Health with respect to well issues in this area of the county. According to the applicant, Mr. Konsler indicated the geography of the area did not lend itself to there being a negative impact on adjacent well recharge rates as the direct result of the proposed development. Further, Mr. Konsler indicated other community wells operating throughout the area had not appeared to impact adjacent property as feared by local residents. This level of data related to an un-drilled well is not easily calculated and is still something that the applicant can not define at this time. The requested figure would depend on the pump that is used, how deep the well is, and other items. Again, see "Attachment I': • BOCC and Planning Board members asked what would happen in the event the proposed stormwater feature was breached, specifically where would the water go. Staff Comment: The applicant indicated the water would flow into the adjoining stream and onto adjacent property. They did not anticipate major flooding, however, resulting from a stormwater breach given the anticipated filtration rate for the feature as detailed on the submitted site plan. The BMP or SCM will be designed in accordance to and subsequently be permitted by Orange Count'sy Stormwater Division under Planning and Inspections Dept. Currently,BMP's/SCM's are designed to accommodate a certain storm, typically lyr-241ir storm in Orange County.All other storms that exceed this runoff amount will utilize an "Emergency Spillway"as is typical on all treatment facilities. Depending upon the type and location of the final designed BMP/SCM a level spreader may or may not be warranted per current county and state regulations. • A BOCC member asked about the possibility of requiring a trail through the Dunhill project to connect to an adjacent parcel owned by the Triangle Land Conservancy (TLC). Further, this BOCC member inquired about why a memo from DEAPR was not included within the quarterly public hearing agenda packet. Staff Comment: Staff has received correspondence from TLC indicating their desire not to have a trail from Dunhill connecting to their property. The concern is over liability issues as well as encouraging access to an existing trail system utilizing existing access points.
