Civil Engineering in Stillwater, Minnesota.
We work with developers, architects, and landowners on civil engineering for Stillwater land development, from Hwy 36 corridor commercial and medical to historic downtown infill, riverfront Wild & Scenic projects, and suburban growth along Manning Avenue.
Licensed Professional Engineer in Minnesota. The engineer designing your Stillwater project is the same engineer answering your call.
(612) 567-2154 →The watershed districts that govern Stillwater stormwater.
Stillwater is unusual for Greater MN in that it has real regulatory watershed authorities. Three districts can apply depending on parcel location.
Regulatory JPA covering Stillwater, Bayport, Oak Park Heights, and surrounding townships along the lower St. Croix. Primary regulator for most Stillwater projects.
Full regulatory WD covering the northern/northwestern portion of the city. Brown's Creek is a DNR-designated trout stream with stricter buffer and thermal-load rules.
May apply on the city's northern fringe. Confirm boundary at project kickoff.
Who reviews a Stillwater project.
A typical Stillwater land development project moves through city, county, state, watershed, and federal review. The Wild & Scenic Riverway adds NPS coordination. We handle the full stack.
Plan review for utilities, right-of-way, surface drainage, downtown historic district, bluffland and shoreland overlays, and Wild & Scenic riverway compliance.
County review for CSAH access including Manning Avenue (CSAH 15), plus SWCD technical review of erosion control and stormwater.
Access and frontage permits on Hwy 36 and Hwy 95.
Watershed permit depending on parcel location. Brown's Creek WD's trout-stream rules drive stricter stormwater on north-side projects.
National Park Service scenic review for sites within the Wild & Scenic riverway corridor. DNR review for St. Croix public waters and Brown's Creek trout designation. WI DNR coordination for projects visible from across the river.
What's different about engineering in Stillwater.
A few things shape how a project actually moves in Stillwater. We design with these baked in from day one.
- •Lower St. Croix National Scenic Riverway. Federal Wild & Scenic designation administered jointly by NPS, DNR, and the city. Any project visible from the corridor gets NPS-level scenic review. The dominant overlay constraint.
- •St. Croix Bluffland and Shoreland overlay. Bluff setbacks, slope-stability, vegetation, and view-corridor rules on river-adjacent and bluff sites.
- •Brown's Creek trout stream. North-side projects under BCWD jurisdiction face stricter buffer, thermal-load, and infiltration-first stormwater rules.
- •Downtown historic district. Adaptive reuse and infill in the historic core run against district design standards and floodplain overlays along the St. Croix.
- •Manning Avenue (CSAH 15) growth corridor. The city's west-edge suburban growth corridor with Washington County frontage coordination on most sites.
What we work on in Stillwater.

Historic-district design standards, St. Croix floodplain compliance, NPS scenic review, and tight-site stormwater.
Single-family and multifamily on the west edge, Washington County frontage, MSCWMO stormwater, and tree preservation.
Brown's Creek WD trout-stream buffer, thermal-load stormwater, and DNR coordination.
Common questions about civil engineering in Stillwater.
How does the Lower St. Croix Wild & Scenic Riverway affect Stillwater projects?
Any project visible from the St. Croix or within the federal Wild & Scenic riverway corridor gets National Park Service-level scenic review on top of city, watershed, and DNR review. This is the dominant overlay constraint in Stillwater. Site lighting, building height, and grading visibility all factor in.
Which watershed district covers my Stillwater project?
Most of Stillwater falls under Middle St. Croix Watershed Management Organization (MSCWMO) — a regulatory JPA covering Stillwater, Bayport, Oak Park Heights, and surrounding townships. Brown's Creek Watershed District (BCWD) covers the northern and northwestern portion of the city as a full regulatory WD. Carnelian-Marine-St. Croix Watershed District (CMSCWD) may apply on the northern fringe.
What is Brown's Creek and why does it matter?
Brown's Creek is a DNR-designated trout stream running through the north side of Stillwater. The Brown's Creek Watershed District regulates stormwater in its boundary with rules tuned to protect the trout designation — buffer requirements, thermal-load limits, and infiltration-first design. North-side projects need that math early.
Do you work on downtown historic infill in Stillwater?
Yes. Downtown Stillwater is a designated historic district with adaptive-reuse and infill activity. Site design works against historic-district standards, floodplain overlays along the St. Croix, and tight-site stormwater BMP integration.
Do you coordinate Washington County and MnDOT permits for Stillwater projects?
Yes. Washington County permits cover county roads including CSAH 15 (Manning Avenue). MnDOT (Metro District) permits are required for access on Hwy 36 and Hwy 95. We prepare and submit both as part of the civil package.
