How to Avoid Delays in Land Disturbance Permit Approval

Quick answer: Many causes of land disturbance permit (LDP) delays are within the applicant’s control. Lock zoning and boundary before you submit, file a truly complete application with the current GSWCC checklist, make the erosion control plan and hydrology report match each other and the county checklist, identify every outside agency review up front, and answer comments precisely without adding unrelated changes. Since July 1, 2026, Georgia’s Senate Bill 447 puts local reviews on a defined clock, but that clock only helps applicants whose plans are complete and engineered to the checklist the first time.

Every round of comments costs weeks of carrying cost, contractor availability and, for builders, sales timing. This guide explains how the Georgia review clock now works and the engineering steps that keep a submittal from bouncing.

How Georgia’s review clock works now

Governor Kemp signed SB 447 on May 11, 2026, and it took effect July 1, 2026, according to Thompson Hine. The signed bill sets these rules for land disturbance permits:

StepDeadline under SB 447What it means for you
Completeness check5 days after filingIf you are not told the application is incomplete, it is deemed complete
Initial decision45 days after filingPermit must be issued or denied
First resubmittal20 daysReview limited to prior comments and your changes
Later resubmittals14 daysSame limit on new comments
State agency reviewClock is tolledTime pauses while a required state agency reviews
Missed deadlineFee refund; mandamus availableNot an automatic approval

Three details matter in practice. First, a denial must state its reasons in writing. Second, the bill defines a “material addition” as anything added to a resubmittal that is not directly related to a reviewer comment, and material additions are treated as a new application on a new clock. Third, a missed deadline does not approve the permit; as the National Law Review explains, it triggers a fee refund and possible mandamus relief.

Not every county is covered. ACEC Georgia reports that the law exempts Paulding County and its adjacent counties from the deadlines unless approved by local referendum. Confirm which rules apply before you plan a schedule around them. Mack’s SB 447 guide covers the law in more detail.

Ten ways to avoid LDP delays

1. Lock zoning and boundary before you submit

Changes during review can restart the process. Forsyth County’s Unified Development Code states that a boundary change needed to meet development regulations, or any change to the zoning classification, conditional use permit or zoning conditions, terminates the pending LDP review and requires a new application under current rules. Resolve rezoning, variances, lot combinations and plat questions first. A feasibility report and concept site plan is the normal place to settle those questions.

2. Submit a truly complete application

SB 447 defines a completed application as one that contains all information and supporting documentation the local issuing authority requires to determine compliance. The 2026 GSWCC plan review checklist is direct: the completed checklist must be submitted with the ES&PC plan or the plan will not be reviewed. Use the checklist in effect January 1 of the year the project is permitted, and include every county checklist, fee and form with the first submittal.

3. Certify the site visit and seal every ES&PC sheet

EPD’s model erosion control ordinance requires every application to include a certification that the plan preparer or designee visited the site before the plan was created. The GSWCC checklist guidance used by Forsyth County requires the certified design professional’s signature, seal and Level II certification number on each ES&PC sheet, or the plan will not be reviewed.

4. Engineer the ES&PC plan to the checklist

The GSWCC checklist is detailed and specific. A plan that is engineered to it, not drafted after the grading is finished, should address:

  • Sediment storage: a minimum of 67 cubic yards per acre drained, in place before and during land disturbance until final stabilization, per the GSWCC checklist guidance
  • Disturbance limits: less than 50 acres at any one time without prior written authorization from the EPD district office, per the 2026 checklist
  • Phasing: separate initial, intermediate and final phase plans that match the actual grading sequence and drainage areas at each stage
  • Soils: soil series delineations, which the 2026 checklist notes are required for plan review and available from NRCS
  • Impaired streams: where the site drains to an impaired stream segment, the segment delineated and at least four additional BMPs from the permit list included
  • Required notes: the checklist’s mandatory statements, such as preventing the escape of sediment by installing controls before land-disturbing activities
  • Practice symbols and details: standard coding from the Manual for Erosion and Sediment Control in Georgia

5. Deliver a hydrology report that matches the plans

Stormwater reviewers check the report and the drawings against each other. Hall County’s commercial plan review checklist calls for pre- and post-developed drainage maps with time of concentration calculations, runoff coefficients based on the Georgia Stormwater Management Manual, hydrographs and routing for at least the 1-, 25- and 100-year storms, stage-storage-discharge tables, outlet control structure details and a sealed report. Cherokee County’s LDP review checklist requires post-developed peak flows at or below pre-developed for the 2-, 5-, 10-, 25- and 100-year storms. If pond elevations, outlet stages or drainage areas differ between the report and the plans, expect a comment. Mack’s stormwater design and hydrology studies are built to those checklists.

6. Resolve buffers and state waters early

Stream buffers can control site layout. Hall County requires state waters on or within 200 feet of the site to be delineated with a 50-foot undisturbed buffer, according to its plan review checklist. Forsyth County’s site development checklist notes that a Section 404 wetland permit must be obtained first where wetlands are affected. Buffer variances and federal permits run on their own schedules, so identify them during feasibility, not after the first comment letter.

7. Identify every outside review up front

An LDP often involves several departments. Forsyth County’s site development checklist lists comments from Engineering, GIS, Water and Sewer, the City of Cumming, NRCS, Environmental Health, the Fire Marshal, the County Arborist and the Tax Assessor. SB 447 requires the local issuing authority to give applicants a list of items requiring external review, and the clock is tolled while a state agency review is underway. Ask for that list early and submit utility, fire, health and DOT items in parallel.

8. Answer comments precisely

Respond to every comment, in order, with the sheet and detail where it was addressed. Forsyth County’s guidance asks for a comment response letter describing the full scope of each revision and warns that if all comments are not addressed, the plans must be re-uploaded and re-reviewed by all required reviewers. The GSWCC guidance it publishes also asks that each resubmittal show the revision date and the entity requesting revisions on the cover and each revised sheet. Under SB 447, avoid design changes unrelated to the comments; they can be treated as a new application.

9. Work the local calendar

Local procedures still set the rhythm. In Forsyth County, LDP plans are due by 5:00 p.m. each Monday, a plan review meeting is held nine business days after the deadline, and the LDP must be issued within 12 months of the initial submittal or a new application and fees are required, according to the Forsyth UDC. Rockdale County’s LDP guide lists a 45-calendar-day initial review, 20 days for the first resubmission and 14 days for later resubmissions. Build your schedule around the specific jurisdiction; Mack’s Metro Atlanta LDP cost and timeline guide and Cherokee County LDP guide cover local specifics.

10. Line up bonds, fees and pre-construction

Approval is not the same as issuance. EPD’s model ordinance allows a local issuing authority to require a bond of up to $3,000 per acre of land disturbance and requires all fees to be paid before issuance. Forsyth County issues the permit at a pre-construction conference with the inspecting department. For sites requiring NPDES coverage, the GAR100003 permit requires the ES&PC plan to be completed before the Notice of Intent is submitted. Have the bond, fees, NOI and certified erosion control personnel ready before approval arrives.

How Mack Engineering keeps LDPs moving

Mack Engineering prepares land disturbance permit plans, grading, erosion and sediment control, stormwater and hydrology designs for residential and commercial projects across Metro Atlanta and Georgia. We build each submittal from the jurisdiction’s checklists, coordinate outside agency reviews in parallel through our stormwater permitting and compliance work, and respond to comments sheet by sheet so resubmittals stay within the scope SB 447 protects.

Mack Engineering is owned by a licensed general contractor, so our ES&PC phasing, grading and pond designs are checked against how sites are actually cleared, graded and stabilized. A plan that can be built as drawn is a plan that is easier to approve, inspect and close out. Engineering plans are prepared and sealed by the responsible Georgia professional engineer of record.

Frequently asked questions

How long does land disturbance permit approval take in Georgia?

Under Senate Bill 447, effective July 1, 2026, a local issuing authority has five days to determine whether an application is complete and must issue or deny the permit within 45 days of filing. After a denial, it must act within 20 days of the first resubmission and 14 days of later resubmissions. Required state agency reviews pause the clock, and some counties are exempt, so actual timelines depend on the jurisdiction and the quality of the submittal.

What happens if the county misses the 45-day deadline?

The permit is not automatically approved. Under SB 447, the local issuing authority must refund all fees collected for the application, and the applicant may petition the superior court for mandamus relief, which receives priority on the court’s docket.

Can a reviewer add new comments on a resubmittal?

Generally no. SB 447 provides that on a resubmittal, the local issuing authority may not issue comments on aspects of the application that are unrelated to its initial comments or to changes made in the resubmission. However, material additions unrelated to the comments are treated as a new application with a new review timeline.

What is the most common reason an ES&PC plan is not reviewed?

The GSWCC plan review checklist states that the completed checklist must be submitted with the ES&PC plan or the plan will not be reviewed, and that the certified design professional’s signature, seal and Level II certification number must appear on each ES&PC sheet. Missing either item stops review before it starts.
