Springdale planners weigh requiring slope‑stability assessments in geotechnical reports

The Springdale Planning Commission discussed May 7 draft ordinance language that would require slope‑stability assessments be added to the town’s required geotechnical reports when excavations are close to neighbors.

Planning staff said the town engineer recommended the assessment be required when the horizontal distance from an excavation edge to a property line is less than twice the excavation depth — for example, a 5‑foot excavation within 10 feet of a property line would trigger the analysis. "The engineer recommended that a slope stability assessment should be required in situations where the horizontal distance from the edge of an excavation to a property line is less than twice the depth of the excavation," Nile Connolly, a staff member, told the commission.

Why it matters: Commissioners said the change is intended to reduce the risk that deep residential excavations — notably for swimming pools and "infinity" pools — undermine neighbor properties or create public‑safety hazards. Commissioners pressed staff on whether the draft…
