Geosyntec Develops TIDEGateway, a Web-Based Assessment Tool for Massachusetts Tide Gates

Posted September 9, 2016 by

Geosyntec Consultants has developed TIDEGateway, a web-based assessment and planning tool for tide gates in the MassBays region, on behalf of the Massachusetts Office of Coastal Zone Management (CZM) and the Massachusetts Bays National Estuary Program (MassBays). This NOAA Project of Special Merit included three components:

  1. Gathering and assessing existing information related to tide gates in the MassBays planning area (Salisbury to Provincetown).
  2. Producing an interactive, web-based inventory and assessment tool to aid managers in the management of tide gates.
  3. Developing and implementing a field protocol to gather tide gate data.

Successful development of TIDEGateway has laid the groundwork for more active and appropriate management of tide gates in the face of sea level rise projections, floodplain encroachment, and aging infrastructure. TIDEGateway provides a central repository for permits, management plans, photos, and other tide gate data collected through field investigations, all through a web mapping interface. It has already provided actionable information to NOAA, the Army Corps of Engineers, and U.S. EPA Region 1, and state resource managers. Managers are able to view a tide gates in relation to natural resources, FEMA flood maps, and nearby infrastructure. TIDEGateway will help inform policy relating to funding and management by providing a more complete view of the breadth, status, and future demands on the state’s tide gate infrastructure. In next stages, TIDEGateway will serve as a vehicle for sharing technical expertise and management tools (O&M plans) among tide gate managers, and could be expanded to include other infrastructure such as tidal culverts.

This project was advised by an Advisory Committee representing a wide range of state and federal agencies. TIDEGateway will be used by these same organizations as existing tide gates are upgraded or maintained and new tide gates are proposed — it is a dynamic resource that will maintain its relevance and value over time.
