r r While the layout of the apartment buildings and parking is an improvement over the original '►stdng.f of buildings, further efforts should be made to cluster the buildings in a more village-life setting, rather than individual buildings separated by parking lots. A reasonable open space buffer has been provided from the fully-cleared sand pit property to the north. Parking conforms with local zoning and appears to be ade� nate. If and how the project might be phased has not been indicated. TRANSPORTATION ISSUES No data is provided regarding traffic generation or impacts. The ITE Trip Generation manual Land Use Code 221, Low-Rise Apartments) indicates an average of 6.59 trips per unit on weekdays, and 7.16 on Saturdays, for similar projects. 120 units would therefore likely generate 791 trips on weekdays and 859 on Saturdays. The traffic generated will add to the general traffic burden on s Mash ee's roadways, and will p y � contribute to some unspecified extent to general lowering of levels of service at local intersections. .However, no specific intersection would likely be seriously impacted by the project alone and Route 130 has sufficient excess roadway capacity in the foreseeable future to deal with project traffic. The access points to the site fro Route -i o and Echo load are on long tangent secbons and present no sight distance problems. There is no scheduled transit service to the site. However, there is demand-responsive transit service provided throughout the town by the tape cod.Regional Transit Authority's"b-Bus". ENVIRONMENTAL 1ENTAL ISSUES Y There are no wetlands on the site. The residential development site is located within a Zone II well recharge area, as well as in a Groundwater protection District under Article VIII of the Zoning -law. The site plan misrepresents the location of the Groundwater Protection District, which -was revised in October 2005 to be consistent with the Zone H. The well in question has not yet been developed, but project wastewater discharge should.not occur within the Zone II and will therefore have to be dealt with off site. A"septic treatment facility"is shown in an open sace area adFac nt to the industrial lots to the east of the Zone II, but no information is provided regarding proposed wastewater volumes or treatment. rased on Title 5 flow of 110 gallons per bedroom, 225 bedrooms would generate wastewater flow of 24,750 gallons per day. Treatment facilities would therefore require permitting by DEP. I E15 has recently adopted a "N Net Nitrogen"" e standard for new wastewater dis hal g g permits in the watersheds of nitrogen impaired emba mems. As the project lies within the watersheds of the Mashpee River Popponesset Bay and Quashnet river waquoit Bay, the No Net standard will apply and dffsetting nitrogen reductions on other properties will have to be provided by this developer. No provisions are shown on the plans to deal with stormwater from the e ctensiveosed - p ro P impervious surfaces, either with regard to volume or, particularly, treatment to reduce nitrogen impact to groundwater. The latter is required by Mashpee zoning and necessary to reduce adverse
