All Services: Surveys, Maps, Plans & SWPPPs

Surveys, maps, engineered plans, and stormwater documents for California projects, from the first boundary question through construction.

How are the services organized?

American Engineering's services are organized into four groups, in the order a California project usually needs them: land surveying, land development and mapping, civil engineering and site design, and stormwater and erosion control.

Land Surveying

Surveys that locate property lines, map the ground, stake construction, and document boundaries and elevations.

Land Development & Mapping

Maps and approvals that create, adjust, or combine parcels, plus early site research.

  • Parcel & Subdivision Maps

    Parcel, tentative, and final maps that take a lot split or subdivision to recording.

  • Lot Line Adjustments & Mergers

    Survey, plat, and sealed legal descriptions to move a shared line or combine lots.

  • Feasibility Studies

    Zoning, title, hazards, utilities, and a concept layout before you commit to buy land.

  • Planning & Entitlements

    Zoning research, exhibits, fee estimates, and agency processing through to a decision.

Civil Engineering & Site Design

Engineered plans that lay out, grade, drain, and serve a site for plan check.

  • Site Layout

    Buildings, parking, fire access, and utilities laid out to setbacks and agency checklists.

  • Improvement Plans

    Street, frontage, storm drain, and sewer designs with calculations and an engineer's estimate.

  • Grading Plans

    Finished grades, drainage, and earthwork quantities on sealed sheets for a grading permit.

  • Septic System Design

    Percolation testing, tank and leach field sizing, and signed plans to county septic rules.

  • Metal Building Foundation Design

    Sealed footing, slab, and anchor rod plans sized to your building's reactions and soil.

Stormwater & Erosion Control

Calculations, plans, and inspections that manage runoff and keep sediment on site.

Which service do I need?

Which survey do I need: topographic, boundary, or ALTA?

A topographic survey maps ground elevations and site features for design; it does not establish property lines. A boundary survey locates and marks those lines from deeds, recorded maps, and field monuments. An ALTA/NSPS survey is a boundary survey prepared to national standards that also shows the title commitment's easements and potential encroachments; lenders and title insurers usually require it.

Do I need a parcel map or a lot line adjustment?

A lot line adjustment moves the lines between four or fewer existing adjoining parcels and cannot create a new parcel; the city or county approves it without a tentative, parcel, or final map (Gov. Code §66412(d)). A parcel map divides land into new parcels, typically four or fewer, under the Subdivision Map Act; five or more parcels generally need a tentative and final map.

Is a SWPPP the same as an erosion control plan?

A SWPPP (Stormwater Pollution Prevention Plan) is the document the state's Construction General Permit requires for projects disturbing one acre or more, including smaller sites within a larger common plan of development or sale, and a Qualified SWPPP Developer writes it. An erosion and sediment control plan is a set of plan sheets a city or county reviews with a grading or building permit. A site can need one or both, depending on its size and the local grading ordinance.

Where should I start if I'm not sure which service I need?

A survey is usually the first step: a boundary survey shows where the property lines are, and a topographic survey gives designers existing grades. Maps, site plans, and stormwater documents build on that base. Send the address and a short project description; the proposal then matches the scope to your agency's requirements.
