OCT-06-1999 08:24 CITY OF BLOOMINGTON LARKIN, HOFFMAN, DALY & LINDGREN, LTD. 6129488949 P.06/07 Mr. Clark Arneson, Manager November 5, 1997 Page 19 including a wetland, at the southeast quadrant of the intersection of West 84th Street and Normandale Boulevard. This property will remain in public ownership and be preserved for open space and stonnwater management purposes. The Application demonstrates that the proposed Phase IV office on the Phase IV Site is not a substantial change that may affect the potential for significant adverse environmental effects under EQB Rules. The BRW Traffic and Air QUality Study and the Peterson WCA Report show that the traffic, air quality and wetland impacts of Phase IV are substantially similar to the traffic, air quality and wetland impacts of the hotel project assessed in the original Nonnandale La.\e EA W. For example, daily trip generation for the Revised Preliminary Development Plan is about 0.4% less than daily trip generation for the approved Preliminary Development Plan, and p.m. peak hour trip generation for the Revised Preliminary Development Plan is only 6% greater than p.m. peak hour trip generation for the approved Preliminary Development Plan. Background traffic volumes on Normandale Boulevard have decreased between 1988 and 1994 due to the .opening of the new TH 169 bridge which has resulted in the diversion oftbrough traffic off of Normandale Boulevard. 1999 traffic volume forecasts for the intersection of West 84th Street and Normandale Boulevard, that include Phase IV, are less than the year . 2000 forecasts used for the Normandale Lake ISP. 1999 p.m. peak hour level of service at the intersection of West 84th Street and Nonnandale Boulevard is forecast to be level of service E with the proposed Phase IV in lieu of the hotel. The currently proposed Phase IV development includes a transportation management plan for the entire office complex (hereinbefore and hereinafter referred to as "Nonnandale TMP"). The Normandale TNlP was not a component of the original Normandale Lake EA W. It is intended to manage travel demand and minimize peak period project trip generation by encouraging and promoting alternative modes of transportation to single-occupancy vehicles. The original Normandale Lake EA W included only a generalized assessment of air quality impacts. Carbon monoxide concentrations with the hotel on the Phase IV Site were subsequently modeled in 1983 and 1990 for the Normandale Lake ISP. The BRW Traffic and Air Quality Study submitted 'With the Application updated previous air quality studies using trip generation for the proposed Phase IV development on the Phase IV Site. Under both scenarios, with either the approved hotel or the proposed Phase IV office on the Phase IV Site, carbon monoxide concentrations will be substantially less than applicable state standards. The MPCA will review the BRW Traffic and Air Quality Study when it is submitted together with the Applicant's request to modify the Normandale Lake ISP to be consistent with the Revised PUD Preliminary Development Plan and PUD Final Development Plan. A modified indirect source permit must be issued before commencement of grading or building construction on the Phase IV Site. Finally, the Peterson WCA Report demonstrates that the Phase IV development on the Phase IV Site complies with WCA wetland replacement requirements. Peterson's review of the original Normandale Lake EA W indicates that the hotel project would have resulted in impacts to the on-site wetland that are -~ J', Q !.l .'" j~ 97
