measure has been updated with this AUAR update to remove old RCWD <br />permit requirements. <br />39. It is anticipated that ditch blocks will be used along the regional system to <br />prevent the draining of adjacent wetlands. By maintaining the existing <br />stormwater runout elevations, the adjacent wetlands are not anticipated to be <br />impacted. While the regional stormwater management plan has been <br />developed to minimize impact to wetlands, some wetlands may be excavated or <br />otherwise impacted once final plans are developed. Impacts to these wetlands <br />will be analyzed under sequencing standards and if impacts cannot be avoided, <br />they will be mitigated in accordance with the Wetland Conservation Act and <br />Section 404 of the Clean Water Act (U.S. Corps of Engineers) within the study <br />area. This measure has been followed where needed and will continue to <br />apply. <br />40. MPCA standards will be enforced for on-site sewage systems. Compliance will <br />be monitored as required. It is assumed that no new on-site sewage systems <br />will be constructed in the area. Reconstruction or rehabilitation of existing <br />systems will be allowed in areas of Large Lot Residential land uses. It is <br />expected that any reconstruction or rehabilitation of existing systems would be <br />done in accordance with applicable standards. This measure has been <br />followed and will continue to apply. <br />41. The study area (except the large lot areas) will be served by municipal sewer <br />that flows to the MCES Interceptor with eventual treatment at the MCES <br />Wastewater Treatment Plant facilities. Municipal sewer will be constructed as <br />part of private development in the study area. This measure has been <br />followed and will continue to apply. <br />42. A sanitary sewer lift station will be constructed by the development projects in <br />the northwestern portion of the study area. This item has been completed. <br />43. Many of the soils in the study area are classified as poorly drained. While these <br />soils do not always meet wetland criteria, they do pose constraints for <br />construction. Housing developments are anticipated to be clustered to avoid <br />hydric soils. Construction will also include slab -on -grade techniques to avoid <br />problems in the study area associated with poorly suited soils. The filling of <br />large areas of unsuitable soils for residential construction will not be permitted <br />within the study area. This will be enforced through City plat review. This <br />measure has been followed and will continue to apply. <br />44. The developer will be required to obtain soil borings to determine the <br />suitability of soils for construction. This measure has been followed and will <br />continue to apply. <br />Final Alternative Urban Areawide Review Update Page 9 <br />Everton Avenue Neighborhood <br />City of Hugo, MN <br />WSB Project No. 10373 <br />September 2017 <br />
