Why Did the City Reject My Site Plan?

Getting a site plan rejected by the city is one of the more frustrating experiences in land development — especially when you’re already invested in the project and ready to move. The good news is that city review comments are almost never random. There are patterns, and most rejections trace back to a handful of recurring issues that a civil engineer would have caught before the application ever went in.

Here are the most common reasons site plans come back from the city — and what it takes to get them approved the first time.

1. No Licensed Engineer Seal on the Civil Site Plan

This is the most straightforward rejection there is, and it still happens regularly. Waco and most other Texas jurisdictions require that a civil site plan be prepared and sealed by a licensed Professional Engineer before a development application can be accepted for review. If a civil engineer wasn’t part of the project from the beginning, this is often the comment that triggers the first call.

It’s not a technicality — it’s a substantive requirement. The PE seal means a licensed engineer has reviewed the site for grading, drainage, utilities, and code compliance and is taking professional responsibility for those elements. No seal, no permit.

2. Easement Conflicts

Utility easements, drainage easements, and access easements are recorded against a property in the deed records and run with the land. They don’t go away because they weren’t drawn on the site plan. If a proposed building, parking area, or structure is located within an existing easement, the city will flag it — and depending on the easement type, the conflict may not be resolvable without significant redesign.

Water line easements, TxDOT right-of-way, and private drainage easements are among the most common culprits. A civil engineer reviews the title commitment and deed records before site layout begins, so the design team knows exactly where easements fall before anyone draws a building footprint.

3. Setback Violations

Setback requirements control how close a structure can be placed to a property line, a street right-of-way, an adjacent land use, or a floodplain boundary. In Waco and McLennan County, zoning setbacks, fire separation requirements, and floodplain development restrictions can each independently limit the buildable envelope on a site.

The problem is that these requirements come from multiple sources — the zoning ordinance, the city’s development code, the International Building Code, and FEMA floodplain regulations — and they don’t always point to the same number. A civil engineer’s job is to work through all of them at the beginning of design so the buildable envelope is established before the architect draws a floor plan, not after.

4. Drainage and Stormwater Deficiencies

Stormwater management is one of the more technically involved elements of a civil site plan, and it’s one of the more common sources of review comments. City reviewers check that the proposed grading and drainage plan doesn’t worsen runoff conditions on adjacent properties or the downstream drainage system.

In Waco and McLennan County, detention requirements can apply to development above a certain size or impervious cover threshold. If detention is required and wasn’t planned for in the site layout, the consequence can be significant — either a redesign to accommodate a detention facility or a reduction in the building program to stay below the threshold. Either way, it’s a problem that’s much easier to solve at the beginning than after a site plan has been developed.

5. Utility Conflicts or Inadequate Service

A site plan needs to show how the proposed development connects to water, sewer, and other utilities. Review comments in this category typically fall into one of two types: either the proposed connections conflict with existing infrastructure, or the existing infrastructure isn’t adequate to serve the proposed use.

Fire flow is a common one — the city will verify that the nearest hydrant can deliver adequate flow for the proposed building type and occupancy. If it can’t, the solution may involve a water line extension or upsizing, which can significantly affect project cost and schedule. These are things a civil engineer checks during preliminary design, not after submittal.

6. Floodplain Issues

If any portion of a tract falls within a FEMA-mapped Special Flood Hazard Area, development within that area is subject to significant additional requirements — finished floor elevations, freeboard, floodplain development permits, and in some cases the need for a Letter of Map Amendment or Revision before a building permit can be issued.

As a Certified Floodplain Manager (CFM), floodplain analysis is part of what we do at Merritt Engineering on every site that has any floodplain exposure. It’s not a detail — it’s sometimes the deciding factor in whether a project is feasible at all in its proposed form.

7. Incomplete or Non-Compliant Plan Set

Cities have submittal checklists, and they use them. Missing sheets, missing details, unlabeled dimensions, non-compliant sheet sizes, or a plan that simply doesn’t address all required elements will generate a comment regardless of how good the underlying engineering is. This category of rejection is entirely preventable with a thorough pre-submittal review against the jurisdiction’s checklist.

What to Do If Your Site Plan Was Rejected

First, read the comment letter carefully. City reviewers are usually specific about what’s missing or non-compliant. Understanding whether you’re dealing with a technical deficiency, a design conflict, or an incomplete submittal determines what comes next.

Second, get a civil engineer involved if one isn’t already. Most of the issues on this list are civil engineering problems — drainage, utilities, easements, floodplain, grading. If the comment letter is technical in nature, it needs a licensed engineer to respond to it and revise the drawings accordingly.

Third, resist the urge to resubmit quickly without fully addressing the comments. A partial response typically generates another round of review comments and adds weeks to the process. Address everything in the comment letter before going back in.

What We Do at Merritt Engineering

We prepare civil site plans for development projects in Waco and throughout Central Texas, and we coordinate directly with city staff during the review process. Some review comments are a normal part of almost every submittal — city reviewers are thorough, and minor clarifications or plan revisions are par for the course.

What a good civil engineer prevents is the other kind of comment — the ones that require going back to the architect, restructuring the site layout, or raising a real question about whether the project works on the site at all. Easement conflicts, setback violations, drainage deficiencies, and floodplain issues caught before design starts are conversations. Caught after submittal, they're redesigns.

When we're brought in before design starts, we do a preliminary site review that covers easements, setbacks, utility availability, floodplain status, and drainage constraints — so the design team has what they need to make good decisions before anything is locked in.

If you've already received a rejection and need help responding, we can review the comment letter and put together a plan for getting the application back on track.

Either way, reach out and let's talk through what you're working with. That's a conversation we're glad to have early.
