impervious area that may be introduced to the site at any time or configuration. Sheet C2.0 shows possible building footprints for all phases of the project, subsequently all areas where secondary development will take place are shown by simply outlining the maximum impervious surface that area may contain. The sizing of the stormwater treatment and pretreatment in this manner allows for no necessary additional stormwater design when the remainder of the campus is constructed. In the Civil plan set, impervious is allocated for a potential connection to the future 1401h St N, even though the anticipated phasing does not project a need for that connection. The storm water design is conservative as it pertains to that aspect of the site. Alternatively, the Architectural phasing plans show the intended phasing of the building and timing of anticipated site improvements. Stormwater Design The Stormwater Management Plan was produced using these maximum impervious areas to allow for no additional stormwater area to be added at the time of developing the remainder of the campus. The stormwater shall be corralled with catch basins which are then routed to one of two pretreatment ponds which pretreat the water before releasing it to the filtration and infiltration basins. Water exists the site to the east through a series of pipes before it reaches the existing catch basin on the west side of Fenway Blvd. Site Design The site is designed to optimize Schwieters manufacturing throughput. The raw materials are to be stored on the north side of the 144,000 square foot building. The finished product will exit the building to the south. Trucks will enter the site from the north entrance and exit on the south. Exhibit 4 in the Civil plan set shows a vehicle tracking truck path. An 8 -inch watermain will run north of the building and connect to the 12 -inch main on the east side of Fenway Blvd. The main will have an 8 -inch service running north and south on the east side of the building to allow for fire protection as well as service for any future building on the south side of the site. Sanitary for the site shall be run north to the existing lift station across the gravel road just to the north. Stubs will be provided to allow for connection to utilities for future building construction with minimal impact to the pavement and other improvements.
