COMMENTS & RESPONSES ConuncIltor : Lance Bernard, Transportation Planner Anoka County Highway Department Comment Date : July 19, 2005 'lhank you ~br your response regarding the Sweetbay Ridge Development Environmental Assessment Worksheet. Study Methods Tile Anoka County Highway Department Development Review Process Manual, dated December 2003, was used tbr the traffic analysis included in the EAW and will be followed by the project developer and the City itl the design of future improvements. The Sweetbay Ridge traffic study determined the impact of this development on the roadway system. The comprehensive plan for the City will determine the future regional impacts of developments that will occur throughout the City. The impacts of this development to the roadway system were evaluated with a standard traffic study. It is estimated that the development will result in more local than regional impacts since the development will not be a region-wide origin or destination on an average daily basis. Incorporation of an average of 12.3 trips per single family household, as suggested in your letter, has only a minor impact on the peak hour trips. An increase is estimated in off-peak trips. Cumulative Impacts Thc combination of this development and regional traffic growth will impact the county and state highway systems. Concerns regarding the impact of this development are responded to in the EAW traffic mitigation measures. The traffic mitigation measures include improvements included as part of the current Town Center I development as well as additional improvement north of TH 10. In additim~ to cumulative impacts associated with Town Center 1, the traffic increase due to Sommerset Station and Brookfield Addition were also evaluated. Traffic from these developments that reaches the study area does not amount to sufficient additional traffic to warrant further analysis. The majority of the traffic fi'om the Brookfield Addition is projected to head east along Nowthen Boulevard and TH 47, while the majority of traffic from the Sweetbay Ridge Addition heads south on Ramsey Boulevard. The total peak traffic estimated for Sweetbay Ridge and Brookfield Addition at the intersection of Alpine and Armstrong is shown below: ' / 20 (15) ] / 10 (25) ! = ~ 40 (20) AM (PM) ,o Alpine ~ ~ 15 (55) < These t"cw trips do not affect the intersection mitigation measures proposed in the Pulte Homes Sommerset Station Subdivision EAW. The mitigation measures proposed will handle the additional traffic fi'om the Brooktield and Sweetbay Ridge Developments.
