Transportation Asset Inventory Data

RPC collaborates with various agency partners in NH to collect and transmit statewide transportation inventory data through the New Hampshire Statewide Asset Data Exchange System (NH SADES) data management tool. SADES is an online-geodatabase that establishes a primary inventory of various assets throughout the state, including: stream crossings, sidewalks, crosswalks, curb ramps, guardrails, and road surfaces (Road Surface Management System - RSMS).

RPC primarily participates in the following inventory programs for two of these assets: Road Surface Management System (RSMS) and the NH Stream Crossing Initiative.

Road Surface Management System (RSMS)

The goal of the RSMS Program is to provide municipalities with

information on their road system’s condition and estimates for future maintenance costs. The main objective of this project is to identify distressed pavement manifestations such as cracking or rutting so that municipalities can look to prioritize maintenance to maximize their return on investment and road quality. This process involves completing a road inventory, condition survey, priority analysis, repair selection, and planning/budget preparation. RPC staff and interns implement the RSMS Program, and participating municipalities receive a report containing a complete road inventory documenting the conditions of locally-maintained roads, as well as a forecast report containing recommended repair methods and estimated repair costs. Inventory data and associated forecasting is managed by RPC personnel and performed through SADES software.

Contact Robert Pruyne or Christian Matthews for more information on the RSMS program or to learn how your community can participate.

NH Stream Crossing Initiative

The NH Stream Crossing Initiative is a statewide effort that is a collaboration of multiple partners, including the New Hampshire Department of Environmental Services (NHDES) and Transportation (NHDOT), Fish and Game Department and the Division of Homeland Security and Emergency Management (HSEM). The initiative aims to evaluate stream crossings to address flood risks and identify problem culverts which may present a hazard to public safety and/or may hinder passage to wildlife. RPC staff and interns collect georeferenced data to locate and assess existing crossings. This data allows for the prioritization of stream crossing replacement projects within a town, watershed or region, and the subsequent data are publicly available via the SADES Stream Crossing Viewer (below).
