Civil Engineering in Frisco, Colorado.
We work with developers, architects, and landowners on civil engineering for Frisco land development, from Main Street infill and Peninsula-corridor commercial to Ten Mile Creek residential, Frisco Bay Marina area work, and reservoir-adjacent parcels along Dillon.

Frisco runs its own engineering standards, with Dillon Reservoir phosphorus loading and Ten Mile Creek setbacks driving most of the design.
Town engineering and development standards govern stormwater within town limits. Frisco does not use MHFD. Summit County criteria apply on unincorporated parcels.
Total-phosphorus loading limits on basins tributary to Dillon Reservoir. BMP sizing and source control are designed to the SWQC standard, not just baseline.
State construction stormwater permit. SWPPP, dewatering, and inspection cadence are standard scope on any one-acre-plus disturbance.
Who reviews a Frisco project.
A typical Frisco land development project moves through town, county, state, federal, and special-district review. We coordinate the full stack.
Plan and engineering review, Main Street design review, Ten Mile Creek setbacks, and reservoir-area conservation compliance.
County review for parcels outside town and 1041 review on major water, sewer, and utility extensions.
Easement and conservation coordination around Dillon Reservoir. Reservoir-adjacent grading and access design routes through Denver Water.
CDOT for I-70 and Highway 9 frontage / access. USFS adjacency where the National Forest abuts.
USACE Sacramento District for Section 404 on Ten Mile Creek WOTUS. CDPHE-WQCD for stormwater. Frisco Sanitation District for sewer service.
What's different about engineering in Frisco.
A few things shape how a project actually moves in Frisco. We design with these baked in from day one.
- •Dillon Reservoir + Denver Water. Reservoir-adjacent parcels hit Denver Water easements, conservation easements, and stricter water-quality regimes than baseline.
- •SWQC phosphorus limits. Summit Water Quality Committee drives total-phosphorus loading limits on Dillon-tributary basins. BMP sizing follows the SWQC standard.
- •Ten Mile Creek + WOTUS. Ten Mile Creek work triggers USACE Section 404 and town stream setbacks. Pre-app coordination with USACE Sacramento avoids late surprises.
- •I-70 + Highway 9 corridor geometry. Frisco sits at the I-70 / Highway 9 junction. CDOT Region 3 access design is a recurring constraint on corridor-front parcels.
- •Snow storage geometry. Snow storage is a real planning constraint at 9,100 ft. We account for plowed snow volumes, melt drainage, and plow access in every site plan.
What we work on in Frisco.
Mixed-use redevelopment on Main Street and the Peninsula. Tight stormwater BMPs, snow storage, and CDOT-adjacent access geometry.
Creek-adjacent residential. Stream setbacks, Section 404, and SWQC-grade water-quality BMPs.
Sites along the Dillon Reservoir shoreline and Frisco Bay Marina area. Denver Water easement coordination and conservation-compliant site design.
Compact site coverage, snow storage, and parking that actually works at altitude on small Summit County parcels.
Common questions about civil engineering in Frisco.
How does Dillon Reservoir affect a Frisco project?
Dillon Reservoir is owned by Denver Water and is a primary Front Range water-supply source. Sites near the reservoir hit Denver Water easements, conservation easements, and a much stricter water-quality regime than baseline. Anything draining toward Dillon goes through Summit Water Quality Committee phosphorus limits and town stream setbacks.
Which drainage criteria apply to a Frisco project?
Town of Frisco engineering standards govern stormwater within town limits. Frisco does not use MHFD. Summit County engineering criteria apply outside town. Summit Water Quality Committee (SWQC) drives total-phosphorus loading limits on Dillon-tributary basins. CDPHE-WQCD issues the CDPS-COR400 construction stormwater permit on any one-acre-plus disturbance.
What are the Summit Water Quality Committee phosphorus limits?
SWQC is a basin-wide regulatory group focused on protecting Dillon Reservoir from cultural eutrophication. New development tributary to the reservoir is held to total-phosphorus loading limits, which translates directly to BMP sizing and source control. We size water-quality BMPs to the SWQC standard, not just baseline.
Does Ten Mile Creek affect Frisco site design?
Yes. Ten Mile Creek flows through Frisco and into Dillon Reservoir. Sites adjacent to the creek hit town stream setbacks, USACE Section 404 on crossings, and SWQC phosphorus controls. We coordinate USACE Sacramento District at sketch plan on any creek work.
When does Summit County 1041 review apply?
Summit County exercises 1041 powers over major water and sewer extensions, certain public utility projects, and selected highway interchanges. Most in-town residential and commercial projects do not trigger 1041, but utility extensions to outlying parcels can. We screen for 1041 applicability at sketch plan.
