Site plan review
The process a city uses to check a proposed development's layout against its zoning and development standards — building placement, parking, access, landscaping, drainage — before construction is approved.
What it means
Site plan review is where a city evaluates how a project sits on its parcel. Where the building goes, how vehicles enter and circulate, how many parking spaces are provided, where stormwater goes, what is planted and screened, how the site is lit.
A reviewer typically works through:
- Dimensional compliance — setbacks, height, lot coverage, FAR.
- Parking and loading counts against the ratios for the proposed use.
- Access and circulation, including drive widths, turning radii, and fire apparatus access.
- Landscaping, buffering, and screening requirements.
- Stormwater management and impervious surface limits.
- Any overlay or corridor standards that apply.
Depending on the city and the project, review may be administrative — staff-level, no hearing — or discretionary, going to a planning commission. Many ordinances set thresholds that decide which path a project takes.
Why it matters
Site plan review is where most development timelines are actually spent. Each round of comments and resubmittal adds weeks, and the same categories of finding recur: a dimension that does not match the code, a parking count computed against the wrong ratio, a landscape buffer missing along a shared line.
It is also where consistency matters most to applicants. Two reviewers reading the same ordinance should reach the same findings on the same plan, and when they do not, the process loses credibility.
An example
A 12-unit apartment building is submitted for review. Staff confirm the setbacks and height, then find the parking count uses a ratio for a different residential category, leaving the site four spaces short. The plan also lacks the required buffer along the rear line where it abuts single-family zoning. Both are fixable, but each costs a resubmittal — and both were checkable against the ordinance before the plan was ever filed.
How Conflation Labs fits in
This is one of the two things we build. Our Site Plan Review Agent reads a submitted plan set — dimensions, parking counts, landscape areas — and checks it against the standards that apply to that parcel, returning findings with a citation to the section behind each one. Reviewers get a consistent first pass; applicants can run the same check before submitting.
Where this comes up in our work
Common questions
Site plan review looks at how the development occupies the site and whether it satisfies zoning and development standards. Building permit review looks at the building itself against the building code — structure, life safety, mechanical, energy. Site plan approval normally comes first, and they answer entirely different questions.
Administrative review of a straightforward project often runs a few weeks. Projects requiring a planning commission hearing typically run two to four months, and each round of comments adds to that. Reducing the number of rounds is usually the largest lever an applicant controls.
