#i <br /> 4 Norn�ado said'f the data is available digitally is not task. What is big question. <br /> 2. A follow up question to the first one. Hover will they develop loading calculations for the 160 <br /> planning zones for non-residential property? <br /> Nortnando said all the other loads are implicit in the coefficients they select. X activity results in X <br /> amount of nitrogen loading. If the town has specific knowledge about a par el,they will use a <br /> different coefficient. Where are a range of coefficients for each land use and there is knowledge that <br /> goes into selecting each one. Normando team will have to meet with Dr. Howes and the Planing Dept <br /> to get information to choose the correct coefficient. <br /> Tom said there are a lot of different situations in Mashpee, including cluster subdivision, nixed uses. <br /> How do you figure in roads? <br /> I onnando said the impervious area is implied in the coefficients. <br /> There are coefficients for non residential/commercial use based on density. <br /> They can create land use coverage based on assessors data. <br /> They do not think there is the budget to develop information on a parcel by parcel basis. You have to <br /> strike a balance between cost and affordability and the sensitivity of the analysis that goes with that. <br /> How important 1s it to go to a second or third decimal point. They are trying to spend an appropriate <br /> amount of money to get the answers lashpee needs. <br /> Tom said the problems he sees are not insignificant, not decimal points. <br /> He does not anticipate the town designing a system for an entire sub watershed, it will probably be a <br /> neighborhood at a time. <br /> Normando is sure the town can point them in the right direction. They can handle revisions to <br /> information that is out there but they do not propose to start from scratch. <br /> . Coordinating nitrogen loading. What is S A's understanding of who is doing what? <br /> SEA envisions a cooperative effort between everyone involved. They will prepare the proposed <br /> nitrogen loading coefficients, will meet with Dr. Howes and the planning dept and then tabulate the <br /> nitrogen loding for each sub watershed and planning unit. They will give,that to Brian and he runs <br /> that information through his model. It will illustrate the hot spots. <br /> Tom asked about'bui l d out? <br /> The planning dt will tell SEA what that will be and they will tabulate the nitrogen loading again. <br /> .holm asked that whenever a tasks is mentioned that will require an additional cost to the proposal that <br /> they mention it. <br /> Nortnando said they are assuming they will have good digital data to work with. They are trying to be <br /> definitive but are they are not sure exactly what is out there. Also,the scope of work will be tinkered <br /> with again by the regulatory agencies. <br /> After they have the loads and know the hot spots,they will meet with the engineers to sec what can b <br /> built. <br /> Tom asked what besides wastewater is figured into the loads <br /> A medium density residential coefficient has all the information implied in it. Its as good as you can <br /> get without site specific monitoring data. <br /> John asked if a cluster subdivision has the same coefficient as a checkerboard one? <br /> The clustered area would have a higher coefficient with a much lower one for all the area around it. <br /> . Public Outreach . 'tom said they did a great job explaining it in their answer. What do they see a s <br /> 2 <br />
