Needs Assessment[sub page) <br /> The Needs Assessment Report identifies the wastewater, stormwater and other nitrogen problems <br /> within the Project Planning Area (PPA). The Report evaluates existing conditions such as <br /> wastewater treatment facilities (WWTFs), physical land features and land uses, and regulatory <br /> issues affecting wastewater facilities. Future conditions are also assessed, such as population <br /> and growth and the potential effects on proposed wastewater collection, treatment and disposal <br /> facilities. <br /> Wastewater Flows and Nitrogen Loading <br /> Wastewater flows and nitrogen loading(or the amount of nitrogen present in the water)were <br /> developed based on MEP reports for the PPA and updated with revised build-out information. <br /> Total existing flows for the PPA, including areas in other communities, are 1.6 million gallons <br /> per day (MGD). Total future flows are estimated at 2.7 MGD. Residential properties will <br /> contribute almost 90 percent of wastewater flows, and wastewater will contribute as much as 80 <br /> percent of controllable nitrogen in the future. <br /> Priority Areas <br /> The Needs Assessment then evaluated the PPA based on previously established planning zones <br /> in Mashpee (developed by the Town) and some broader areas for the adjacent towns. Each of <br /> these were then grouped into larger geographic areas and compared to various criteria to begin <br /> the steps of prioritizing nitrogen removal needs. <br /> The assessment looked at the following criteria: <br /> 1. Was a nitrogen removal percentage assigned by MEP? <br /> 2. Was the area identified as having high nitrogen loading per acre? <br /> 3. Was the area identified as being year-round or seasonal (which will come into play for <br /> implementation purposes)? <br /> 4. Were there other non-nitrogen considerations (i.e. Santuit Pond phosphorus, etc.)? <br /> 5. Was the area located within a Zone II (a water supply protection area established by the <br /> state)? <br /> Areas with MEP removal rates, high nitrogen loading and a greater number of year-round <br /> residents were weighted the highest for this analysis. "Primary Priority Areas" included the first <br /> three criteria, and possibly others as well. "Secondary Priority Areas"had either one or two of <br /> the higher weighted criteria. <br /> "Tertiary Priority Areas" typically only include one of the top three criteria and at most only two <br /> of the five criteria identified above (with the exception of Barnstable's portion of Shoestring <br /> Bay). The majority met the year-round and/or Zone II criteria only;therefore, they are more <br /> likely to be dealt with in later phases of a recommended plan. These areas also often included <br /> one or more of the following types of characteristics: <br /> • low nitrogen loading per acre <br /> • upstream location in the watershed to take advantage of attenuation(or natural nitrogen <br /> reduction) <br /> • large areas of open space <br /> 5 <br />
