l -35E Corridor Final AUAR September 26, 2005 Design of the new interceptor is now in progress. Lino Lakes provided flow estimates, based on the Comprehensive Sanitary Sewer Plan Scenario, to MCES in March 2005 (see Item 18 for additional information). MCES has directed the designers to provide capacity in the new interceptor for 2.0 MGD average daily flow. Discussions are currently underway between Lino Lakes and MCES regarding the capacity to be provided in the new interceptor. Assuming capacity remains at 2.0 MGD, the existing and new interceptors will have adequate capacity for projected development through at least 2030 under any of the three AUAR Scenarios. However, ultimate development as projected by Scenarios Two and Three could eventually exceed capacity. If the city chooses to amend its Comprehensive Plan to accommodate components of Scenarios Two or Three, then a subsequent revision to the Comprehensive Sanitary Sewer Plan will be required. The Comprehensive Planning process, including review by the Metropolitan Council, is the appropriate process to resolve any potential sewer capacity issues. Cultural Resources Ten precontact archaeological sites have been recorded in the north and western portions of the AUAR area, and numerous others have been documented in proximity to it (see Table 25 -1). For the most part, sites are located in proximity to water: Centerville Lake, George Watch Lake, Peltier Lake, Rondeau Lake, Clearwater Creek, Hardwood Creek, and Rice Creek. The undisturbed landforms adjacent to these bodies of water have the greatest potential for containing intact archaeological sites. Several sites have been identified on slight rises within the wetlands surrounding Rice Creek; therefore, those wetlands, and the northern portion of Peltier Lake, have high potential to contain intact archaeological resources. Further, those undisturbed areas adjacent to known sites are also considered to have high archaeological potential. Because of the high level of archaeological sites in the AUAR area, appropriate levels of historical and archaeological surveys in areas identified as having high potential for containing cultural resources will occur prior to future development. This is intended to mitigate any intentional or unintentional damage to, or destruction of, important archaeological sites and historic properties without due process and consideration. The 106 Group created a map that shows areas with a high potential for archaeological sites. Given the sensitive nature of this information, this map cannot be included in the AUAR document, nor can it be made available to the public. The city will have this map on file and consult it when development applications are submitted for review. If a development application falls within an area that is considered to have a high potential for archaeological sites, the city will require that the following steps and procedures involved in the identification and analysis of any archaeological sites is followed prior to development: • Conduct a Phase I archaeological survey within the area of potential effect (APE). The objective of the archaeological fieldwork is to determine if there are archaeological sites in the areas identified as having high potential for such, and define the extent of those sites that may be impacted by development plans. • Conduct a Phase II archaeological survey. If archaeological resources are uncovered within the APE that may be eligible for listing on the National Register of Historic Places (NRHP) a Phase II survey should be conducted. The objective of the investigation is to determine whether archaeological resources are eligible for listing on the NRHP. • Plan for avoidance or conduct Phase IlI data recovery. If a significant archaeological site is identified that will be impacted by development, avoidance is recommended. If this is not possible, then a data recovery of the site should occur. xv
