Managing stormwater takes more than adding pipe where water collects. American Fork City needed to understand how runoff moves through its drainage system, plan improvements, and meet its stormwater permit requirements. Franson Civil supported that work through studies, design, construction observation, and program planning.

Our work began with a study of stormwater flow paths in the eastern part of the city. We reviewed rainfall data and drainage basin boundaries, then modeled runoff to estimate peak flows. The study also evaluated three crossings along State Street, where the City needed to understand whether the drainage facilities had enough capacity following UDOT’s highway widening.

We later designed storm drain improvements near 1120 North. The work included survey and mapping, system design, a highway bore requiring UDOT approval, bid documents, and construction observation. Along 300 North and 200 West, we designed 500 feet of storm drain line to connect the existing system to a concrete ditch and observed construction.

Planning for future needs was another part of the City’s work. To update its stormwater master plan, we built a new model using GIS data, soil information, drainage basin boundaries, rainfall, and the amount of paved and other surfaces that shed water. The model identified system deficiencies and informed a list of future projects with cost estimates.

We also worked with the City’s Storm Water Advisory Committee to update its Storm Water Management Program. Committee members represented the city council, irrigation company, local businesses, and residents. Their input helped shape practices and procedures for public education, development reviews, and ongoing inspections. We prepared schedules and budgets for meeting the permit’s continuing requirements.

These efforts gave American Fork City a clearer picture of where stormwater goes, which facilities may need attention, and what it will take to carry out future improvements. The program update also gave the City a practical framework for protecting water quality while keeping up with its permit responsibilities.
