Commission backs tighter standards to ensure infrastructure connects between developments

The Planning Commission recommended changes to the engineering standards’ general requirements to require that public infrastructure — streets, water, sewer, drainage, gas, power and communications — provide for future extension to adjacent properties and be installed to the boundary lines of new developments when topographical barriers do not exist.

City Engineer Clark Kent Fugal used a cluster of subdivisions near Iron Springs Elementary School as an example of how earlier phases were not stubbed out to allow connectivity, forcing residents to use arterial routes. "When no topographical barriers exist that all improvements shall be installed at the boundary lines of the development," Fugal said, and staff inserted a definition of topographical barriers (including but not limited to mountains, canyons and extremely steep slopes) to limit exceptions.

Commissioners discussed measurement standards and potential exceptions, and staff said the city engineer would determine whether a physical barrier exists and that engineered mitigations (pedestrian access, maintenance access) could still be required where full street stubs are impractical. The commission voted to recommend the change.
