Ms. Emily Crudup December 7, 1987 Page Two 1. A dual absorption field system should be required to be installed at the time each lot is developed (alternating use between the two fields on a regular basis) , with an additional back-up field area also being required. Supporting information on this approach is enclosed for your consideration. OWASA staff recognizes that this will result in increased construction costs and greater initial clearing for the system installation; however, the long-term benefits to water quality, public health and future owners of the property should offset these costs. 2. The primary and backup septic tank system sites identified and approved by the Orange County Health Department should be clearly designated on the plats and deed/survey for each lot. These sites must be required to remain undisturbed and reserved by present and future owners for such use. OWASA has been informed of one reported case where a reserve site identified by the HealthDepartment was rendered unusable due to construction of improvements after the initial residence had been completed. The Lynwood Subdivision plan shows septic tank drainfield locations crossing property lines. This would seem to present a potential problem for future maintenance work on the field area. It is unclear whether the proposed systems are individual units or a cluster. system. Sedimentation and Erosion Control/Stormwater Runoff Control: When smaller lots are created from larger lots on a "piecemeal" approach, the cumulative effect on sedimentation and erosion and stormwater runoff must be fully considered. Sedimentation and erosion controls and stormwater management measures must be required in these instances, and assurances provided that such measures will be properly maintained over the long-term. OWASA has previously expressed concerns regarding sedimentation and erosion control problems within the University Lake watershed. Reservation of Sanitary Sewer Easements: Presently, the OWASA Board of Directors has an interim policy which strictly limits the extension of public water and sewer services into the University Lake . watershed. This interim policy will be reconsidered following the completion of the comprehensive watershed study, which is in progress. Property owners in the watershed or Rural Buffer area should be required to provide a 30 feet wide public utility easement along the low-lying area of the property to facilitate the timely extension of public sewer service into and through the proposed subdivision in the event that action is determined necessary and desirable in the future. Recommended easement locations can be provided, if requested. Thank you very much for your consideration of O1ASA staff's comments relative to this proposed subdivision. Please do not hesitate to contact me if you need any additional information. Sin rely, Patrick K. Davis Acting Executive Director wp Enclosure
