Community Technical Assistance Program


The I-93 Community Technical Assistance Program (CTAP) is a New Hampshire Department of Transportation (NHDOT) 5 year initiative to assist 26 communities that will be affected by the rebuilding and expansion of Interstate 93. These 26 communities include:

  • Allenstown
  • Atkinson
  • Auburn
  • Salem
  • Bow
  • Candia
  • Chester
  • Concord
  • Danville
  • Deerfield
  • Derry
  • Dunbarton
  • Fremont
  • Goffstown
  • Hampstead
  • Hooksett
  • Hudson
  • Litchfield
  • Londonderry
  • Manchester
  • Pelham
  • Pembroke
  • Raymond
  • Salem
  • Sandown
  • Windham


The purpose of CTAP is to promote beneficial patterns of growth among all 26 communities to minimize the negative effects of growth on community services, open space, school systems, traffic, environmental quality, and existing residential and commercial development.

More information about the CTAP program is available at the New Hampshire (NH) Department of Transportation (DOT) website.

CTAP is coordinated by NH DOT, four of the state’s regional planning commissions (Central, Nashua, Rockingham and Southern New Hampshire), as well as a number of non-governmental organizations such as the Society for Protection of New Hampshire Forests as directed by a CTAP Steering Committee made up of representatives from each of these groups. Windham is part of the Southern NH Planning Commission and more information is available on the Southern New Hampshire Planning Commission (SNHPC) website.

Planning Stages

CTAP consists of three main planning stages:

Community Planning Assessment

A questionnaire designed to help communities determine where they are on the planning curve and where their current planning and zoning will take them in the future. View the Community Assessment Report (PDF) which resulted from this process.

Visioning & Planning

The process in which a community pictures the future it wants and plans how to achieve it. View the Town's Community Planning Roadmap (PDF).


Utilizing the community assessment and existing community plans actions are developed and implemented that move the community forward to its ultimate vision. The Projects done under Year 1 and Year 2 highlight how the Community Assessment and the Visioning and Planning are being Implemented.
