Lot width is measured at the creek and ;the <br />building line of the parcel. There are several lots that do not meet the lot width criteria. <br /> <br />¸2. <br /> <br />The wetlands on the parcel would benefit from a buffer that would prevent intensive lawn <br />management to the wetlands' edge. The wider the buffer the better, but at least 25' .would <br />be a good startir~g point. The width should be greater as the slope increases. Monuments <br />on the buffer edge at each lot line will help homeowners remember where the buffers <br />start, and will help inform those unfamiliar with vegetative buffers. <br /> <br />Untreated stormwater should not be allowed to run directly off of the streets into the <br />wetlands or creek. Runoff volumes and rates should be held to their pre-development <br />levels through appropriate landscaping, minimizing impervious surface, maximizing <br />i n filtration opportunities for stormwater and providing for adequate ponding. <br /> <br />Trott Brook is one of the City's great amenities. It can be protected by preventing an <br />increase in srormwater runorT and sediment from this development, and by ensuring thai~ a <br />natural, vegetative buffer exists, or is created between the homes and the creek. <br /> <br />Thank you for the opportunity to comment. Please feel free to call me if you have any questions. <br /> <br />Sincerely, <br /> <br />Tom HOvey <br />Area Hydrologist <br /> <br />IJNR Information: 651-296-6157 · <br /> <br /> /\ti /!qual ()[)lmr(tmiry <br /> <br />-888-646-6367 · TTY: 651-296-5484 * 1-800-657-3929 <br /> <br /> Prin~ed on Recycled Pal)er Conlaininu a <br /> <br /> <br />
