42- Updated Rogers Road Sewer Service Concept Plan and Cost Estimates February 8; 2011 Page 2 process It does not address any nearby or surrounding properties that have been discussed in other venues or meetings convened during the past three and a half years by Orange County or other parties, such as the Rogers - Eubanks Neighborhood Association. It is important to consider this concept plan and cost estimates within the larger community in which sewer service for all or a portion of the area might realistically be implemented, rather than in isolation from those nearby properties. • If the Town or others decide to pursue this or alternative sewer concepts, additional engineering and professional services will be needed to provide site -level detail and an overall determination of project feasibility. Guide to the Concept May Rogers Road Small Area Planning Area The study area is delineated by a black and white dashed border on the accompanying map. All currently platted parcels within this area could be served either by existing (green) or potential (red) sewer lines, except for three parcels in the extreme southeastern corner of the study area, which are expected to have access to a separate sewer line that will serve the Church of the Advocate to be constructed on a parcel located between Merin Road and the railroad right-of-way. Existing and Potential Sewer Lines: Existing OWASA sewer lines and manholes for the entire mapped area are shown in solid green. Sewer lines needed to serve the unsewered portions of the Rogers Road Small Area Planning Area are shown in red._ Arrows indicate the direction of sewage flow. Within the Rogers Road Planning Area Only: Platted parcels for which OWASA sewer service is currently available are colored in light or dark green. Parcels which are already connected to the OWASA sewer system are indicated with cross - hatching. (Note: This is shown only for properties within the Rogers Road Planning Area.) Preliminary Cost Estimates Project Costs — The attached table summarizes preliminary estimated construction costs of the concept plan. Total estimated project costs are summarized in the table below. These were derived through the same methods that OWASA uses to estimate its own capital project costs. Further details are available on request. The following important caveats are noted: • If the Town or others decide to pursue this or another sewer system concept, additional engineering and professional services will be needed to provide site -level detail and overall determinations of engineering feasibility.
