INCA stormwater and utilities management includes master-planning, modeling, best management practice selection, and design. This experience includes designing ponds, infiltration systems, diversion structures, water quality treatment basins, sedimentation ponds, and stormwater outfalls; preparing erosion and sediment control plans for construction sites; evaluating treatment alternatives; estimating costs for all types of stormwater systems; and evaluating open channel designs and hydraulics, including fish passage.

Utility design and coordination are key components of any urban project. Careful consideration of utilities prior to project construction will avoid considerable problems and expense during construction.

INCA coordinates utilities early in the design of project. INCA engineers use subsurface utility methods to match design and coordination needs to a project. INCA designs incorporate such relocated utilities as water, sewer, combined sewer, natural gas, and underground conduits systems for electricity, cable and fiber optics.
