I I. I I I I I I I III I I I I I I I f I 4. During development of the Guidant Campus Master Plan much consideration was given to preserving the natural landscape of the project site. Both the wetlands and undeveloped uplands in the northwest and the wooded area in the northeast will be preserved as a result of this effort. The preservation of this natural landscape will protect bird/wijdlife habitat and thereby have a positive affect on park facilities near the study area. Currently storm water runoff is carried via storm sewer to the receiving wetlands and carries with it the sediment and pollutants associated with pavement runoff. The final drainage plan for the project site will include storm water ponding and infiltration areas to treat storm water runoff prior to entering the study area wetlands. These measures as well as the reduction in impervious surface area on the project site will protect the study area's water quality and have a positive affect on associated water bodies. 5. The cxisting City of Arden Hill's trail along Lexington Avenue provides a connection to two Ramsey County Regional trails located along CR 96 (CR 96 Regionaj Trail) and further north at CR J (Rice Creek North Regionaj Trail). Although the internal sidewalk system planned for the Guidant Campus does not directly connect to the City trail, proximate access is available. 6. The City of Arden Hills is a fully developed community. As such, there are limited devejopment opportunities for additional housing. However, in conjunction with the anticipated reuse of portions of the Twin Cities Army Ammunition Plant, the City is evaluating housing alternatives relative to its existing housing stock, existing and future employment opportunities, and demographic trends. 7. A) The Draft AUAR cover types table (Table 4 in the Draft AUAR) includes cover type acreage for the proposed ponds ("other-created ponding"), however; the table does not include cover type information for the infiltration areas (refer to Tabje 4, Footnote 2 of the Draft AUAR). As Guidant has continued to develop the stonn water treatment strategics in coordination with the Rice Creek Watershed District (RCWD) for the project site, more detailed covcr typc information has become available. The Final AUAR cover type tabje (Tabje 4) includes the most recent estimates of the acreage for storn1 water ponding as well as infiltration areas. B) As the RCWD and Guidant dcvclop the ovcrall drainage plan for the project site including the stonn water treatment strategies, efforts will continue to prcserve as much woodcd/forest acreage as practicable. Due to the restraints of providing rate control and water quality treatment for a site this size, not all the storm water ponds and infiltration areas could be sited within areas of existing or planned lawn/landscaping. In order to properly locate infiltration areas downstream of pond locations and upstream of the wctland locations, it is not possible to avoid locating ponds and infi Itration areas in existing wooded/forested areas. The location and proximity of the water treatment areas is crucial to the function of the Guidant Campus Master Plan Responses to Comments - 3- January 2003
