Executive Summary: |
On August 9, 2016, the City Commission received a presentation on the two options for the Kasold Drive reconstruction project from Bob Billings Parkway to approximately 6th Street.
Option 1: Traditional Street - 2 lanes in each direction (11 ft.) - Median with turn lanes - Bike lanes (5 ft.) - 8 ft. multiuse path and 6 ft. sidewalk - Signal at Harvard - Roadway width back of curb to back of curb 69 ft., plus sidewalk & greenspace - Estimated roadway only construction cost - $5.4 million
Option 2: Complete Street - 2 lanes in each direction (6th St. to W. 9th Ct. and 14th to 15th) - 1 lane in each direction between 14th St. and W 9th Ct.) - Median with turn lanes - 5 ft. bike lane with 3 ft. buffer - 8 ft. multiuse path and 6 ft. sidewalk - Roundabout at Harvard - Roadway width is 56 ft. to back of curb to back of curb, plus sidewalk and greenspace - Estimated roadway only construction cost with KDOT grant - $4.16 million
Staff has held several neighborhood/stakeholder meetings and developed a website as part of the public participation plan.
The website includes preliminary details and estimates for both options.
A Traffic Impact Study (80 pages) evaluated all options and modeling was completed for existing and future conditions.
Both options improve existing conditions and provide certain complete street elements. Staff is recommending the Option 2 – Complete Street option for the following reasons: - Reduced conflict points improves safety - Slower speeds improves safety - Improved conditions for pedestrians and cyclists - Shorter street crossing distances - Buffered bike lane - Less maintenance, snow removal and street sweeping - Less stormwater infrastructure and runoff - Over $1 million less cost than Option 1 – Traditional Design
