Wetland type and boundaries were approved as part of a Notice of Decision submitted on December 29, 2017. 7. There are three existing wetlands on the subject property with impact proposed to Wetland 1 (0.44acres), impact to Wetland 2 (1.14 acres) and no impact proposed to Wetland 3. A wetland replacement plan that purchases wetland banking credits has been approved. 8. The applicant will need to apply for a "no -loss" for the temporary impact of construction for the proposed stormwater facility in the NW corner of the site on wetland 3 (excavation or drainage). Grading, Street, and Utility Plans 9. Sanitary Sewer service was originally proposed to come from the 42" MCES interceptor along the east side of Fenway Avenue as identified in the Comprehensive Sanitary Sewer System Plan. The applicant had difficulty providing sewer service to the proposed site due to the proposed site elevation, existing sewer elevation, and existing storm sewer elevation that creates a conflict. With that said, staff reviewed alternate sewer service options that involve connecting the sanitary sewer to a pipe in a sewer sub district directly north of the proposed site. The sanitary sewer in this location discharges directly into the lift station adjacent to the Fenway Place subdivision. The lift station wet well and sanitary sewer forcemain are adequately sized, however the lift station pumps will need to be upsized to maintain capacity for remaining areas in the sub district for which it was originally designed. The applicant will need to compensate the City of Hugo $15,000 for the upsizing of the lift station pumps. This is a cost-effective solution as the applicant would otherwise need to install their own lift station on site. The sanitary sewer that extends south from 1401h Street along the west side of Fenway Avenue will be in a 45 -foot public drainage and utility easement. The main will be publicly owned and maintained by the City of Hugo. Individual services extended from this main will be the responsibility of the owner. 10. Watermain Service is available from the 12 -inch trunk main along the east side of Fenway Avenue. The applicant will be extending an 8 -inch watermain across Fenway Avenue and into the site that will be capable of serving their proposed and future buildings within the site. The Hugo fire department has reviewed the proposed hydrant coverage within the site and feels it meets their requirements. All proposed watermain will be private and be the responsibility of the owner for maintenance.
