16 across each parcel rather as opposed to the point as which they could provide sewer to just that parcel. The cost to extend 3400 linear feet of 8" sewer line along Jones Creek from the nearest existing OWASA sewer line (from a point in Jones Creek on the north side of the Lake Hogan Farm subdivision) all the way across the southern-most County owned parcel to at least its common east-west property line with the middle County owned parcel is estimated to fall between $340,000 and $425,000. This cost would be incurred regardless of whether the southern parcel would be occupied by either the school or the park. The cost to extend 3100 linear feet of 8" sewer line further along Jones Creek to near the northern boundary of the middle County owned parcel and thence north overland across the northern County owned parcel to Eubanks road is estimated to fall between $310,000 and $387,500. Again, this cost would be incurred regardless of whether the middle and northern parcels would be occupied by either the school or the park. If it were to be assumed that a sewer extension cost comparision could be made between two potential scenarios: 1) in which the park, located on the southern and central parcels, would extend a sewer line to the northern boundary of the southern parcel (there is no sewer demand from or need to extend sewer to and through the center parcel) from Hogan Farm; and the school, located on the northern parcel, would extend a sewer line from the southern boundary of the middle tract to Eubanks Road; and 2) in which the school, located on the southern parcel, would extend a sewer line to the northern boundary of the southern parcel (again, there is no sewer demand from or need to extend sewer to and through the center parcel) from Hogan Farm; and the park, located on the northern parcel, would extend a sewer line from the southern boundary of the middle tract to Eubanks Road; it would be found that there would be a slight sewer extension cost savings to the park project (in the range of $30,000 to $37,500) to have the park located on the northern parcel. However, it is possible that a park located on the southern parcel would not extend OWASA sewer to serve its concession/ restroom facility (depending instead on the use of on-site wastewater treatment options) until the sewer line had been extended to serve a school located on the northern parcel. Under this scenario, the cost to the park associated with sewer utility construction would be limited to approximately $160,000 ($100,000 for a phase I on-site system and $60,000 for a full phase development sewer connection) and the bulk of the sewer extension costs (in the $650,000 to $812,000 range) would fall to the school. In terms of the cost of extending water service to the park or the school, there is a significant difference in expenditures to extend service to the northern parcel as opposed to the southern parcel for park use. As the southern parcel abuts the existing OWASA waterline, extending water service to that parcel is a service connection. The park, under the assumption that fire protection is not necessary and irrigation will be provided by well water, needs only a 3" service line with a construction cost of approximately $50 to $75,000 (with an automatic flushing system as noted in the 9/23/04 memorandum). However, if the park is located on the northern parcel which is not adjacent to the existing OWASA waterline, OWASA will probably require that a
