City engineer leads plan‑reading training for Planning Board

City Engineer Joe Levarier led a February 4 training session for the Saco Planning Board on reading civil engineering plans, interpreting topography and contours, and evaluating stormwater treatment options.

Levarier told board members the session was intended to give them “tips and tricks” to read plan sets more efficiently so they can identify constraints such as wetlands, setbacks, test pits and existing utilities before a public hearing. He walked the board through an older city plan set for a Foss Road public‑services site to show how sheets are organized and where reviewers should look first.

The training focused on a handful of recurring review tasks: identifying the plan index and legend, finding existing conditions (wetlands, vernal pools, soils borings), reading contour intervals and tracing watershed flow, and separating layout, grading and utility plans so each remains readable. Levarier recommended highlighting major contours (for example, every 5 or 10 feet) and using aerial basemaps to make existing features easier for reviewers and neighbors to visualize. “Water flows perpendicular to contours,” Levarier said, urging members to…
