ALTA Surveys for Phased Commercial Developments

A commercial project built in phases keeps changing shape. The land surveyed for phase one may look very different from the land surveyed for phase three, even though both sit on the same site. An ALTA survey has to keep up with that change. How well it does affects financing, permits, and how smoothly each phase connects to the next.

In Washington DC, many commercial sites move forward one phase at a time. This often depends on funding or new tenants signing on. A survey scoped for the whole project on day one can miss details that only matter once later phases take shape. 

Defining the Surveyed Property for Each Development Phase

The land surveyed for one phase is not always the same as the land named in the original purchase or ground lease.

Early on, a phased project often has one legal description for the whole site. As phases move forward, that description may split into smaller pieces. Each piece may cover a single building, a parking structure, or a utility zone. Each of those smaller areas may need its own boundary before an ALTA survey can be useful for that phase.

This matters most on sites with shared driveways, shared utility lines, or easement agreements between phases. A surveyor working on phase two needs to know exactly where phase one’s buildings sit next to the new phase boundary. This is more than just knowing where the whole property line falls. Getting this wrong can cause problems later. This is especially true if phase one and phase two end up owned or leased by different parties.

Before ordering a survey for any single phase, check whether that phase already has its own recorded legal description. Or find out if it still falls under one larger parent parcel. This changes how the surveyor sets up the work and what the survey can legally show.

Matching ALTA Survey Scope to Current Phase Decisions

The scope of an ALTA survey should match what the current phase actually needs. It should not try to cover the full buildout that may not happen for years.

The 2026 ALTA and NSPS Minimum Standard Detail Requirements set the baseline items every ALTA survey must include. These cover things like boundary evidence, recorded easements, and access to public streets. Beyond that baseline, Table A lists optional items clients can add depending on the project. For a phased project, the right Table A items often change from phase to phase.

A phase focused on a parking garage may need detailed elevation data and utility locations near the garage footprint. A later phase focused on a retail building may need different items, such as parking counts or zoning setback checks. Adding every possible item to every phase raises cost without adding useful information.

Before ordering a survey for a new phase, review what that phase actually needs to decide. A few common examples:

• Checking setback rules for a new building footprint
• Confirming utility easement locations near planned underground work
• Recording finished improvements from an earlier phase that sit near the new work area
• Checking access and traffic flow between finished and upcoming phases
• Confirming flood zone or elevation data if grading has changed since the last phase

Reviewing this list with the design team before ordering a survey keeps the scope matched to what the project needs right now.

Separating Existing Conditions From Planned Improvements

An ALTA survey shows what already exists on the ground. It does not show what a design team plans to build.

This matters more on phased sites than on single-phase projects. Most phased sites have a mix of finished construction, active construction, and empty pad sites all on the same overall property. A survey ordered for phase three needs to clearly separate the finished phase one and two buildings from the new phase three design. The finished buildings are existing conditions. The new design is a planned improvement that has not been built yet.

Mixing the two up can cause real problems. If a surveyor treats a planned building footprint as if it already exists, the survey can mislead a lender or permit reviewer who relies on it. The same is true if a design team assumes the survey already shows grading that has not happened yet.

The best way to avoid this mix-up is simple. Share the current site plans with the surveyor before the survey work starts. That way the surveyor knows which areas are finished construction and which areas are still just plans. The final survey drawing can then label each one correctly.

Coordinating Phase Limits Across Project Documents

Survey information for a phased project usually needs to match several other documents. These can include site plans, easement agreements, and sometimes ownership documents if each phase will be held separately.

A mismatch between the surveyed phase limits and the limits shown on a site plan or recorded easement can slow down permit review. It can also create title questions later. This is more likely when different consultants prepare different documents at different times, without checking each new document against the surveyed boundary.

One helpful step is to share the current ALTA survey with every consultant working on the next phase. This includes the civil engineer, the title company, and any attorney writing easement language. This gives everyone the same starting point. It also cuts down the chance of a boundary or easement description drifting away from what the survey actually shows.

For sites near historic districts or federally owned land, this kind of coordination matters even more. Extra layers of review may rely on that same boundary and easement information.

Preparing Survey Information for the Phase Handoff

Every phase of a commercial project eventually hands off information to the next phase. This might mean a new contractor, a new lender, or a new design team picking up where the last phase left off.

A clean handoff usually includes the current ALTA survey, any as-built records from finished construction, and a clear list of which Table A items were used and why. This gives the incoming team a real starting point. It saves them from having to piece together site history from scattered documents.

It also helps to flag any survey information that may need an update before the next phase starts. Site conditions change during construction. Grading shifts. Temporary utilities get removed. Access points sometimes move. If a lot of time has passed since the last survey, or if conditions have changed since then, ask a surveyor whether an update makes sense. This can stop the next phase from relying on old information.
