I I. Watermain I The site has both 8 and I2-inch ductile iron pipe (DIP) watermain looped through the District, as I shown on Exhibit 4. Water service is currently provided to all existing businesses along West Round Lake Road, including Welsh's Phase I site, currently under construction. It appears, I however, that the I2-inch loop within the former 14th Street NE right-of-way will require removal due to the amount of grading necessary for the proposed development of parcels within Welsh Companies' Phases II, III, and IV improvements. The 8-inch watermain within West Round Lake I Road extends south to 13th Street NE, and east to the southerly limit of 14th Street NE, where it reconnects to the I2-inch watermain extending east to Old Highway 10. The existing 8-inch I watermain will most likely remain in place to maintain existing services, pressure, and redundancy, at least until the area in the southwest corner of the site is developed. At such time, I the 8-inch watermain could be utilized as part of the development's internal watermain loop, or it could be rerouted to better facilitate the development of those parcels. Although a detailed I water distribution system analysis has not been conducted, the existing pressures at 14th Avenue and West Round Lake Road are sufficient to provide basic service for the development. It is I- recommended that the entire area be analyzed upon the City's receipt of potential development plans which should better define land use and fire flow requirements in the overall GBD. I Storm Sewer I The existing site currently has no developed storm drainage facilities. According to City ordinance, development within the GBD must treat on-site runoff within each respective property, I prior to discharging to the City's proposed storm water system. The overall site generally drains from the north to the south and west into various wetlands on the site and, eventually, into the I Minnesota Department of Transportation (MnDOT) right-of-way, where it collects at the approximate location of the Minnesota Transfer railroad bridge, and is directed west into the I MnDOT drainage system. As a result, storm water discharge after site development will be limited to the existing storm water runoff rate under the undeveloped condition. I In addition to the storm sewer restrictions outlined above, there are currently several wetlands I within the District. The size, location, and boundaries of these areas must be delineated by a certified wetland expert prior to any plan approval for the area. The wetlands lie both within I. private properties and within proposed public right-of-way. It is anticipated that the development of the area will require the mitigation of several wetlands. Moreover, it has been proposed, and I discussed with Welsh Companies, that the developer mitigate any wetlands within public right-of- " FEAS-520.089 -.J- 520-089-10
