Addendum to the DRAFT Design Study Report

The West Dimond Boulevard Upgrade – Jodhpur Street to Sand Lake Road Draft Design Study Report (DSR) has been distributed for review and public comment.  As a result of the current funding limitations and identified need to expedite construction of proposed improvements between Sand Lake Road and Westpark Drive, the Municipality of Anchorage’s Public Works Department has elected to divide the project into two phases (see map below).  Phase I improvements will extend from the Sand Lake intersection to approximately 850 feet west of the Westpark Drive intersection (Station 77+00).  Phase I pedestrian facilities will not extend west of the Westpark Drive intersection.  Phase II improvements will extend from Station 77+00 to Jodhpur Street.  Final design and construction of Phase II will not advance until full construction funding becomes available.  Dividing the project into two phases will allow construction of Phase I to be accelerated and commence in 2014.

Review comments for the entire alignment are welcome and will be addressed.  However, particular attention should be focused on Phase I improvements.  Send us your comments or bring them to the open house scheduled for Wednesday, August 28th, 2013.

DRAFT Design Study Report Available for Review

The Municipality of Anchorage’s Public Works Department is pleased to release a public review DRAFT of the Design Study Report (DSR) for the West Dimond Boulevard corridor in west Anchorage. The upgrade project began in 2005 with problem identification through extensive community input from a Citizen’s Advisory Committee (CAC), the Sand Lake Community Council, area homeowner’s associations, user groups, agencies and local and state officials.The DRAFT Design Study Report documents the alternatives development and evaluation phase including screening all possible solutions to recommend alternatives to go forward to the next phase, preliminary design.

A public open house is scheduled for Wednesday, August 28, 2013 at Dimond High School Multi-Purpose Room from 5:30 PM to 8 PM to provide an opportunity for the community to review, comment and ask questions of the Municipal Project Managers and consultant design team.

Design Study Report Summary

The Municipality of Anchorage (MOA) is proposing to upgrade West Dimond Boulevard from Jodhpur Street to Sand Lake Road.  West Dimond Boulevard within the project area is a two-lane, east-west collector without shoulders, curbs or pedestrian amenities.The project’s primary objectives are to:

  • Provide pedestrian and bicycle amenities within the project corridor;
  • Improve safety by improving horizontal and vertical geometry; separating vehicles from pedestrians and bicyclists; and calming traffic.
  • Upgrade the roadway and intersections to current municipal road standards;
  • Upgrade a public facility which has adequate capacity for the future growth and development of the area for the next 20-30 years;
  • Provide major intersections that will operate at adequate service levels in the future; and
  • Reduce long-term road maintenance by providing greater durability to the road surface.

Recommended improvements along the corridor include:

  • Reconstruction of the roadway surface and structural section with asphalt pavement, including shoulders to curb and gutter, with separated pathways on each side of the roadway;
  • Roadway drainage will be collected along the curb and gutter and conveyed through catch basins and storm drain pipes to low spots, matching the existing drainage patterns.
  • A continuous roadway lighting system, using Light Emitting Diode (LED) technology;
  • Landscaping which will focus on preserving the natural, rural character of the roadway.  The roundabout center islands will provide an opportunity for a gateway into the neighborhood; and
  • Modern single-lane roundabouts at both the Sand Lake Road and Westpark Drive intersections.
