Marietta Pool Removal Permit Guide 2026: Navigating City Hall & Cobb County Codes

The Jurisdictional Split: Where Are You?

The first thing any Marietta pool removal specialist will ask is: "Are you inside the city limits?" This isn't just for travel time—it determines which set of "Laws of the Land" apply to your backyard.

If you are within the **City of Marietta** limits, you are dealing with the **Public Works Department** and the **Building Inspections Division**. If you are in unincorporated areas (with a Marietta mailing address but outside city lines), you fall under **Cobb County Community Development**. In 2026, both jurisdictions have tightened their environmental and geotechnical requirements to prevent the "sinkhole epidemic" caused by poor fill-ins in previous decades.

1. The 2026 "Permit Stack" for Pool Demolition

In Marietta, you don't just get a "Pool Permit." You are essentially pulling a stack of specific authorizations. Here is the technical breakdown of what is required before the first excavator track hits your lawn.

2. Impervious Surface Ratios (ISR) & Your Yard

One of the most complex aspects of pool demolition in Atlanta—and specifically Marietta—is the **Impervious Surface Ratio (ISR)**. The City of Marietta has strict caps on how much of your lot can be covered by "hard" surfaces like concrete, decking, and pool water.

When you remove a pool, you are effectively "giving back" impervious surface area to the city's stormwater management system. This is a massive win for your permit approval. By demonstrating a net reduction in ISR, we can often fast-track approvals for future projects like outdoor kitchens or guest houses. Our permit experts calculate your current ISR and provide the city with a "Post-Removal Impact Statement" to maximize your property's future building potential.

3. The E&S Plan: Protecting Marietta's Watershed

Marietta is famous for its rolling hills and proximity to the Chattahoochee watershed. Because of this, the **Soil Erosion and Sedimentation (E&S) plan** is the most scrutinized part of your permit application. You cannot just dig; you must prove that you won't wash Red Clay into your neighbor's yard or the city storm drains.

4. Section 710.05: The "Technical Finish" Mandate

There is a specific code section that often trips up amateur contractors: **The Drainage Requirement**. In Marietta, you cannot leave a pool shell in a state where it can trap water. Even for a "Partial Removal," the permit requires a 3x3 foot hole to be punched in the bottom and filled with gravel for vertical drainage.

However, for a **Full Engineered Removal**, the city inspector will require a visual inspection of the empty cavity before any backfill occurs. This is to verify that the plumbing lines have been capped at the source and that all debris (rebar, tile, coping) has been removed. If you fill that hole before the inspector arrives, they will make you dig it back up. At **Atlanta Pool Removal Pros**, we coordinate these inspections with City Hall so your project never hits a "Bureaucratic Brick Wall."

5. 95% Proctor Compaction: The Only Way to Build

If your future plans include a deck, a garage, or even a heavy storage shed where the pool used to be, your permit needs to reflect a **Geotechnical Compaction Standard**. The City of Marietta and Cobb County both recognize the **95% Proctor Compaction** as the institutional standard for "Buildable Land."

This involves layering the soil in 6-8 inch "lifts" and compacting them with specialized machinery. We don't just "guess" at the density; we provide a compaction report for your permit file. This document is your "Get Out of Jail Free" card for future property sales—it proves to the next owner (and their bank) that the land is structurally sound and won't sink. This certification is often required by Marietta permit officials before they will close out your demolition permit.

6. Geotechnical Verification Standards: Sarah's Testing Protocols

For buildable-grade compaction, we work directly with a licensed civil engineering firm to supervise the backfilling process. Sarah Jenkins, P.E., our geotechnical consultant, manages our density testing protocols. In Marietta, the native Cecil clay loam is highly sensitive to moisture changes, demanding careful analysis. Before we place any backfill soil, Sarah takes samples of the imported soil to the laboratory to run a Standard Proctor test. This plots a curve showing the Optimum Moisture Content (OMC) and the soil's Maximum Dry Density.

During backfilling, as we place the soil in thin 6-to-8-inch layers (lifts), Sarah uses a nuclear density gauge to measure the in-place dry density and moisture content of each lift, confirming it achieves at least 95% Modified Proctor density (ASTM D698). Once the testing is complete, she issues a stamped compaction certification report that we file with the Cobb County Building Inspections Division to officially close out the demolition permit and clear the property title.

7. Arborist Regulations in Marietta: Preserving the Canopy

The City of Marietta is a certified Tree City USA, and the municipal Planning and Zoning Board enforces strict canopy preservation codes. If your backyard pool lies near protected trees (any hardwood with a DBH greater than 12 inches), you must secure an arborist review before bringing heavy machinery on site. The Critical Root Zone (CRZ) is protected using a 1-foot-per-inch DBH radius. If our compact loaders need to pass through this zone, we must install tree protection fences and lay 6 inches of organic wood chips topped with heavy timber bridge mats to distribute vehicle weight and prevent root compaction.

If root excavation is unavoidable, we deploy pneumatic air-spades to expose roots safely and prune them cleanly with specialized saws to prevent decay, coordinating all steps with the city arborist to ensure tree health and avoid compliance penalties.

8. Utility Coordination: Capping and the 811 Protocol

Before any demolition equipment begins breaking concrete on your Marietta property, a critical step is the official coordination of utility caps. Under Georgia law, the "Call Before You Dig" (811) protocol must be initiated at least three business days prior to excavation. This ensures that all underground utility lines—including Marietta Power and Water, Atlanta Gas Light, and Comcast fiber optic lines—are clearly marked with standard color-coded paint. However, the 811 service only locates public utility lines. Any private lines running from the home to the pool house, pump, or heater must be located and isolated by our team.

For the water capping process, Marietta Water requires the main supply line to the pool's auto-fill system to be severed and capped at the backflow preventer. This capping must occur on the customer side of the meter to ensure no leaks occur post-demolition. For gas lines feeding pool heaters, Atlanta Gas Light requires a licensed technician to isolate the line at the gas meter, purge the line of residual gas, and cap it with a threaded steel plug. Electrical circuits running to the pump, filter, and underwater lighting must be disconnected at the sub-panel, with the breaker locked out and the wiring pulled back to prevent accidental re-energization.
