City Council Meeting Minutes May 19, 2015 Page 8 of 34 Trip Generation - Staff anticipates approximately 6,150 vehicle trips would be generated daily from DELO, DELO Plaza, and Miners' Field. Approximately 460 trips would be generated in the moming peak hour and 500 trips in the evening rush hour. Trip Distribution — Staff used the distribution assumptions from both the DELO and DELO Plaza traffic studies: These distribution assumptions, shown below were generated from select Zink studies of the DRCOG regional traffic model. Staff then generated assumptions of how the Lee Avenue Extension would further influence the distribution of generated trips. Trip Assignment — Staff anticipates approximately 850 vehicles a day will use the Lee Avenue Extension with approximately 65 vehicles during the morning and evening peak hours. This equates to approximately 1 vehicle per minute on Lee Avenue during the peak periods. The proposed intersection would operate at a similar acceptable level of service to the current Jefferson Avenue and Pine Street intersections in Old Town. Alternative Considered — Staff did an analysis of extending the dedicated southbound right tum lane from Hwy 42 to Pine Street as an alternative to the Lee Avenue Extension. Impacts of extending the southbound right turn lane north from Pine Street to the South Street intersection were examined. Staff kept the centerline of Hwy 42 in its current location and added half of the needed northbound left tum lane from Hwy 42 to South Street, a southbound bike lane on Highway 42, the requested extended southbound right tum lane, a sidewalk, and a 3 -foot retaining wall as Hwy 42 is 3 feet higher than Miners' Field. The illustration demonstrates extending the Hwy 42 southbound right turn lane to Pine Street north would have significant impacts on the Miners' Field. This alternative was not recommended by staff during the 42 Gateway Study because it did not improve traffic operations over what was proposed for the Pine Street intersection. The 95th percentile queue in the 2035 model for the southbound right turn lane from Hwy 42 to Pine Street does not justify the extension. The impact of the Lee Avenue extension would be equal to traffic impact on downtown streets. Mayor Muckle called for Council questions and comments. COUNCIL COMMENT Council member Leh asked how many cars would use Lee Avenue during peak hours. It was confirmed one per minute. The Highway 42 Revitalization Framework Area Plan states Little Italy and Miner's Field not be affected by zoning changes and remain Residential /Medium Density. It appears the Gateway Project shows the 3 lane plan and its superiority are a consideration of the Little Italy /Miner's Field neighborhood. Planning and Building Safety Director Russ noted the study specifically addressed the zoning and the neighborhood impact.
