PROGRESS STATUS UPDATE

2020 Subdivision Construction Manual Rewrite

August 18, 2020:

On Tuesday, August 18th, the Matanuska-Susitna Borough adopted the 2020 Subdivision Construction Manual.  There were four amendments proposed, three were adopted and one failed.  The 2020 Subdivision Construction Manual will be in effect beginning January 1, 2021.

January 20, 2020

In April of 2016, the Mat-Su Borough Assembly signed Resolution 17-003 supporting the rewrite of the 1991 Subdivision Construction Manual (SCM).  Department of Public Works and Planning staff then began work on a draft update. Once created, a group of subject matter experts was formed to review the document, consisting of local Land Surveyors, Civil Engineers, Developers, Homebuilders, Board Members, and borough staff.  Their review meetings began in June of 2018.  They met 27 times over the next 18 months, with all but three meetings being full-day meetings.  The 2020 Subdivision Construction Manual is the result of that effort.

Major changes to the document are:

  • Removed Sections on Subdivision Agreements and Inspection Fees (these are addressed elsewhere in code).
  • Removed Driveways from the SCM and created a new MSB Chapter 11.12 Driveways (Driveway Ordinance Project Page click here.
  • Changed the title of the Nonresidential Road Section to Major Road Corridors and added Frontage/Backage and Connector Street Standards.
  • Combined all of the Residential Street Design Criteria into one table for ease of use.
  • Increased Roadway width for Residential, Residential Subcollector, and Residential Collector Roads for added safety.
  • Increased ADT from 6 daily trips to 10.
  • Major rewrite of the Drainage Section.
  • Added a Section on Easements.
  • All drawings updated and placed within the body of the manual rather than in an appendix. (finalization of drawings is underway and will be included in the document upon their completion.)

Upon completion of the final draft, the SCM Working group adopted their Resolution 20-01 with the following recommendations:

  • Assembly approval of the 2020 Subdivision Construction Manual
  • Assembly approval of an ordinance creating MSB 11.12 Driveways
  • Assembly consideration of a variety of other actions to address transportation issues in the valley.

A tentative schedule for completion of the project along with other supporting documents can be found in the "Project Docs" box on the right.

Project Benefits

The benefits of updating the Subdivision Construction Manual are to have a more efficient and safe road system; the state and federal requirements and design guidelines for road construction have changed greatly since the manual was crafted and amended.  The advancements in engineering and technology over the past 25 years allow for a greater range of roadway and utility construction options that are not addressed in the 1991 manual.

Project Status

Assembly adopted the 2020 Subdivision Construction Manual on August 18, 2020.
