Aerial view of North Point Mall with large parking lots and tree-lined edges. — North Point Mall sits amid expansive parking lots in Alpharetta, where approved redevelopment can still hinge on later permits and outside conditions.

A city council can approve hundreds of homes on Monday while the property remains wooded and quiet on Tuesday. Construction may still be months or years away.

That gap often causes confusion around North Atlanta. Neighbors may assume approval means bulldozers are coming immediately. When nothing happens, they may conclude that the project has been canceled.

Neither assumption is necessarily correct. A rezoning vote settles what a property may be used for. It is only one step in turning a concept into streets, utilities and buildings.

The vote answers a land-use question

Rezoning changes the development rules applying to a property. A special-use permit allows an activity that requires additional approval within the existing zoning district. A change in conditions modifies requirements attached to an earlier decision.

These votes usually involve a conceptual site plan, proposed uses and conditions governing matters such as density, buffers, road connections or building design. They do not substitute for detailed construction drawings.

That distinction is visible at the Johns Creek United Methodist Church property. The city approved 48 detached homes on part of the church campus in September, but the decision did not authorize home construction. Engineering plans, stormwater designs, subdivision plats and permits remain ahead.

A project can therefore be legally approved without being ready to build.

The concept must become an engineering plan

After zoning, developers must show that the approved idea can function on the actual land.

Johns Creek’s land-development review examines site layout, stormwater management, erosion control, environmental protection, trees, landscaping, roads and compliance with city, state and federal requirements.

That review involves more than one department. Plans may pass through engineers, planners, arborists, fire officials and other specialists. Reviewers can require corrections, creating several rounds of revised drawings before approval.

The process becomes especially complicated when a property contains streams, floodplains, steep slopes, wetlands or difficult road access.

The 195-townhome community approved at 3842 Old Milton Parkway in Alpharetta illustrates that stage. The builders still must complete stormwater and hydrology reviews, secure land-disturbance and building permits and satisfy the conditions attached to the August zoning approval. A planned creek crossing could require additional federal approval.

The number of homes has been decided. The precise engineering needed to build them has not.

Clearing land and constructing buildings require different permits

A land-disturbance permit generally governs grading, clearing, erosion controls, stormwater facilities, roads and utility installation. It does not automatically authorize houses, apartments or commercial buildings.

Before Johns Creek issues a land-disturbance permit, the developer must complete plan review and provide required fees, stormwater agreements, bonds and contractor information. A preconstruction meeting and site inspection follow.

Building permits come later. Johns Creek requires a related land-disturbance permit to be issued before the developer applies for the building permit. The city’s building-permit process then moves through plan review, permit issuance, construction inspections and a certificate of occupancy or completion.

Gwinnett County follows the same broad division. Its development review covers grading, erosion controls, stormwater systems, utilities, floodplains, stream buffers and landscaping. Separate building and trade permits govern the structures and their electrical, plumbing, mechanical and fire-protection systems.

A cleared site therefore may be further along than an untouched property, but it still may not have permission to begin vertical construction.

Conditions can determine whether a project happens at all

Approval can include requirements that reshape a project, increase its cost or make construction dependent on another event.

Alpharetta’s approved North Point Mall plan is an unusually clear example. Jamestown has said the redevelopment will not proceed in its approved form without an NHL franchise. The zoning exists, but the event needed to activate the plan has not occurred.

Other projects may depend on a land purchase, financing, shared-parking agreement, sewer connection, road improvement or environmental permit.

A developer is not generally required to build simply because a rezoning was approved. Financing conditions can change. Construction prices can rise. A property can be sold with its approved zoning, or a plan can remain dormant until the market improves.

That is why an approved rendering should be understood as an authorized possibility, not a construction schedule.

The public hearing is usually the most important moment for neighbors

Residents generally have their greatest influence during the zoning and special-use process, when elected officials are deciding whether the use belongs on the property and what conditions should apply.

Later permit reviews are often administrative. Staff members are checking engineering plans against the zoning decision, development regulations and construction codes. They are not holding a new vote on whether residents want the development.

That makes the approved conditions important. A traffic improvement, buffer, sidewalk or building limit discussed during the hearing should appear in the final approval. If the developer later seeks a substantial change, another public process may be required.

Residents following a project should save the final ordinance or zoning conditions rather than rely only on the original application. Council members can revise a proposal before approving it.

How to tell whether construction is actually close

The most useful question is not simply whether a project was approved. It is which permit has been issued.

A land-disturbance permit indicates that site preparation can move forward. Recorded subdivision plats establish legal lots. Building permits authorize specific structures. Inspections document progress, and certificates of occupancy allow completed buildings to be used.

Permit portals maintained by cities and counties can reveal more about timing than an old rendering or rezoning headline. Developers may also announce financing, contractors or construction schedules once a project reaches that stage.

Until then, an approval means the government has accepted a land-use plan. It does not mean every engineering problem has been solved, every dollar has been secured or construction is ready to begin.
