Land Surveyors in Long Beach, CA

Canal-front homes in Naples, beach lots on the Peninsula, 1920s bungalow districts inland and a harbor that sank as oil came out of the ground. The work is part flood mapping, part old-lot boundary research, and a large share ADU planning.

A City With Water on Three Sides

Long Beach runs from the harbor in the west to Alamitos Bay in the east, and a lot of its most valuable housing sits within a few feet of sea level. Naples is built on three islands threaded by the Rivo Alto and Naples canals, with a City-maintained seawall and a public walkway between most homes and the water. The Peninsula is a single row of blocks between the ocean and the bay, and Belmont Shore sits just behind it. Much of that shoreline is state tidelands the City has held in trust since 1911, which is why an accurate line between private lot and public frontage matters so much here.

The Ground That Moved

Production from the Wilmington oil field made the harbor district sink, by about 29 feet at the center by 1958, until water injection that began in 1953 finally stopped it. Monuments and benchmarks from that era moved with the ground. When an old plat or elevation disagrees with today's measurement, subsidence is often the reason, and the answer is to tie to current control rather than the record.

Bungalow Districts Inland

Bluff Park, California Heights and Bixby Knolls hold much of the city's 1920s and 1930s Craftsman and Spanish Revival housing. These are older, narrower lots with detached garages at the back, and those rear garages are where a lot of the city's backyard units are now going.

What Gets Ordered Here

An elevation certificate is routine in Naples, the Peninsula and around the bay. Bungalow owners adding a unit start with an ADU site survey, and disputed fences or garages call for a boundary survey. Architects on waterfront and hillside remodels ask for a topo survey. Commercial deals near downtown and the port need an ALTA/NSPS land title survey, new builds need construction staking and a final as-built survey, and neighbours redrawing a shared line use a lot line adjustment.

Long Beach Survey FAQs

Why do old elevation records in Long Beach sometimes disagree with new ones?
Oil, gas and water production from the Wilmington field made the harbor area sink, reaching about 29 feet at the center by 1958 before water injection brought it under control. Benchmarks set before and during that period moved with the ground, so an older drawing can reference heights that no longer hold. Current work ties to the present vertical datum rather than trusting a mid-century number.
My house backs onto a Naples canal. Where does my lot actually end?
The Naples seawalls are public infrastructure the City maintains, and the canal walkway is public right-of-way, so the private lot usually stops short of the water. A boundary survey locates the recorded line against the wall, walkway, gates and dock so you know which of those improvements sit on your land and which do not.
