There are 2 <br />dry wells per single family home and they connect to down spouts. <br />Ms. Waygan informed about the new requirement for single recharge through natural drainage <br />patterns and vegetation. Driveways shall be vegetative swales or sand filters, organic or <br />similar, for removing nitrogen from stormwater. <br />Mr. Yergation states MassDEP declares roof runoff from non-metal roofs to be clean, and will <br />allow recharge into the ground, so this water is technically clean. <br />Ms. Waygan stated this is the bylaw. It needs to be addressed in some nutrient removal <br />system. <br />Mr. Pesce commented that this is not standard recommended practice. Roof runoff has a small <br />component of nitrogen from the atmosphere. A vegetative swale will attenuate and direct roof <br />runoff down and channeled to an area to drain in the yard. Recharging runoff back into the <br />ground simulates and enhances. He is much more in favor with this approach, but understands <br />it is not in compliance. <br />Ms. Faulkner stated a rain garden could also go there or even a large plant right in the area <br />where the gutter drains. <br />Ms. Waygan stated a condition could be added so it doesn't get lost during review. Regarding <br />the lighting plan, there should be a certification of no light pollution for abutters. <br />Mr. Yergation will provide a photometrics plan for the one light at the entryway. If additional <br />lighting is proposed, he will confirm with the client, and it will be easily provided. <br />Ms. Waygan stated there are lighting plans and lights get installed, but then they don't comply. <br />They are able to go back and change the light. For these types of purposes, we need <br />something that addresses lights. <br />7 <br />
