IW#406 of Alford Associates, Inc. for a building addition, parking lot expansion and associated drainage improvements within 100 feet of wetlands and watercourses. Property located at 135 Freshwater Boulevard (Map 56 Lot 24) Zoned I-P [Submitted February 11, 2004; Received February 17, 2004; PPE March 2, 2004; MPHCD March 23, 2004]. Wilson Alford, Jr. represented the applicants. Agents Storey and Szewczak stated that they have reviewed all information and correspondence on this matter and are up to date on this application. Mr. Alford explained that the subject parcel is located on Freshwater Boulevard. The existing building is 18,288 square feet, existing pavement & walks equals 41,432 square feet for a total coverage of 20.45% of the 6.4 acre site. Proposed plans will increase the size of the building area to 31,394 square feet and the pavement and walks areas to 110,143 square feet for a lot total coverage of 48.46%. Mr. Alford went on to say that the topography leaves Freshwater Boulevard as the highest point on the site. Vegetated areas include lawn and secondary growth from the time of the original construction of the building in the mid 1980's. Existing roof leaders flow overland to the wetlands. All of the existing storm drains from the warehouse and parking areas go to the storm water ditch without being treated. The wetland ditch is manmade and low quality. They are the only wetlands located on the actual property. Mr. Kevin Rothschild Shay, architect for the applicant explained that the driveway will be adjusted, and the front landscaping and buffers to the north west will be enhanced. The parking area will include landscaping and an efficient layout to minimize parking as much as possible. 270 to 290 employees are expected to be working there. Mr. Alford presented drawings of the site after proposed construction. Roof drainage will be collected and piped into a closed storm drain system. Three outlets are located along the eastern section of the site, draining into the proposed water quality basin. Catch basins are proposed to have extra deep sumps and hoods. 4' sumps will be at the end of the line; the remaining catch basins will have 2' sumps. He also presented a profile drawing of the basin. Water will enter in three areas, build up and flow over a stone berm into the existing swale. It is sized to hold up to 1.6" of rain before exiting into the second berm. Retainage of the water will allow sediment to leave and for the water to be filtered by grasses. In response to Agent Szewczak's question of whether or not the berm will become less effective over time, Mr. Alford explained the construction and materials of the berm. He stated that the berm has some filtering capabilities, but its' main purpose is to slow the flow of water. Sediment will likely remain around the inlet points in the basin. Most fines are already filtered out when the water reaches the berm. The berm is protected by Mirafi fabric so it will not become clogged. Also, the flow will not be high velocity. Water quality is accomplished by holding and filtering through the grasses. Mr. Alford briefly reviewed his proposed maintenance schedule for the storm water management system. It includes annual sweeping of the walks and parking areas, monthly inspections and annual clean-out of catch basins and monthly inspection of the swale. Mr. Alford a |
