RE:	Kasold Drive, Clinton Parkway to 31^st Street Street, Storm Sewer, Waterline Improvements Project No. PW0903 Project Final Design and Schedule

Project Background.

November 2008	Voters passed 0.3% sales tax for infrastructure and equipment
May 5, 2009	Received City Commission approval to begin negotiations for engineering services with Bartlett and West (B&W)
June 9, 2009	City Commission authorized agreement with Bartlett & West for design
June 27, 2009	Presented to City Commission, 2009 Street Maintenance Program and Sales Tax Projects
August 31, 2009	Public Meeting

Project Description.

The pavement on Kasold Drive, from 31^st Street to Clinton Parkway, will be replaced with 10” concrete, and the sidewalk and recreational path will be connected around the curve to 31^st Street to provide a continuous pedestrian and bike facility.  The need for turn lanes and medians has been reviewed during the design process.  Traffic control will probably be the most significant issue as several neighborhoods have only a single exit access onto Kasold.

Attached:

1. Typical section with 11 feet lanes and landscaped median/center turn lane – Item 1
2. Horizontal layout – Item 2a, Item 2b, and Item 2c.
3. Sight distance improvements at 24^th Terrace – Item 3
4. Establish left and right turn lanes at E. 1200 Road on Kasold curve – Item 4

     Connect multiuse path and sidewalk around Kasold curve  - Item 4

Design. 

· Improved site distance on vertical curve at 24^th Street.  To improve the vertical curve and sight distance at 24^th Street the adjacent retaining wall and recreation path will be replaced. The blocks in the existing wall will be reused.  In addition to improving the vertical sight distance, reconstructing the existing retaining wall allows us to build it outside of the horizontal sight triangles, which will additionally improve intersection safety at 24^th Place and 24^th Street.

· Medians/Left-Turn Lane.  The road will be 5 lanes wide.  Medians will occupy the center lane where left turning movements are not necessary.

· Traffic Control.  One lane in each direction will be maintained.  Access to the offices both east and west of Kasold at Clinton Place and Clinton Parkway Court will be maintained.  Left turns will be restricted through the construction limits except at Clinton Place and Clinton Parkway Court.

· Utility Relocation.  We continue to try to minimize all utility relocation.  A force main along the curve will need to be relocated for a few hundred feet to install the right-turn lane.  Some adjustments for the waterline to get around storm sewer inlets will be needed.    Other utilities will complete their relocations prior to bidding.

· Right-of-Way/Easements.  The project did not require any right-of-way.  Construction easements have been obtained in a few places to appropriately tie in grades for maintenance.

· Intersection at Clinton Parkway.  Future traffic projections and intersection geometrics indicate the necessity for dual left-turn lanes.  The existing median will be removed and a yellow striped area will replace the median so that in the future the second left-turn lane can be added without reconstruction.  Additionally, a right turn lane will be added to the project to improve traffic flow and efficiency of the intersection.

Schedule. 

The project was planned for a spring 2010 bid opening.  The Stimulus Programs placed a lot of additional work on KDOT.   At this time the project will be scheduled for a November 2010 letting.  This will allow the project to be completed by December 2011. 

Funding. 

Current estimate for this project is approximately $6 million.  This project is to be financed from the approved sales tax.  KDOT is contributing approximately $1 million. 

Action Requested:  Approve final design and schedule.

Respectfully Submitted,
