Lakeville, then University Gardens.

Wikipedia says the area, once farmland and known as Lakeville and Little Neck, was built up in the early 20th century. The University Gardens subdivision that gives the hamlet its name went up in the late 1920s with 218 homes and 17 commercial properties; architect H.C. Meyer designed much of the Waverly Hills section in the 1940s; and in the 1950s the 652-family Great Neck Terrace garden-apartment complex, 28 buildings designed by Samuel Paul, was built at the northwest corner. The CDP covers 0.6 square miles, all land.

The Census Bureau's latest five-year survey counts about 1,600 homes, with a median year built of 1950. 33% went up in the 1950s, 29% before 1940, and 5% after 1980. 55% are single-family detached houses, 36% are in buildings of five or more units, and 86% are owner-occupied.

So a typical house here has drain and water lines around 76 years old unless they've been replaced. Slow drains in several fixtures, a gurgling floor drain or rusty water from one tap are signs to have the main line and supply piping checked. With so many pre-1940 homes, some still have galvanized or older supply piping in the walls; we plan repairs around what's actually there.

Oil to gas means new gas piping.

The ACS shows 76% of homes heat with utility gas and 16% with fuel oil. Switching means properly sized gas piping to the new equipment, and often to the water heater, range and dryer. We do the gas line work. We don't sell or deliver oil.

On the sewer.

University Gardens isn't listed separately in Nassau County's health department sewer list; Wikipedia says the whole hamlet is inside the Belgrave Sewer District, which the county list shows as the Belgrave Water Pollution Control District (516-487-2759). A backup that stops at your house is usually in your own line to the street; we clear it and repair or replace the line. If neighbors are backed up too, call the Belgrave Water Pollution Control District (516-487-2759).

Little mapped flood risk.

FEMA's current flood map puts none of University Gardens in the high-risk flood zone.

Houses and garden apartments.

The Census counts only about half of University Gardens' homes as single-family detached houses; Great Neck Terrace alone has 652 apartments. In a co-op or garden-apartment building, the shared stacks and mains usually belong to the building, so check with the managing agent before work that opens walls; inside your unit, we handle the fixtures, supply lines and drains.

Water: Manhasset-Lakeville Water District.

EPA's service-area map puts about 96% of residents on the Manhasset-Lakeville Water District, with about 4% on the Water Authority of Great Neck North; your bill is the final word. The main supplier's most recent 90th-percentile lead result was 1.6 ppb, under the 15 ppb action level; lead usually comes from a home's own pipes and fixtures, so results vary house to house. In EPA's UCMR 5 testing, the main supplier's highest single PFOA/PFOS result was 5.3 parts per trillion. EPA's 4 ppt limits apply as a running annual average starting in 2029, so one high sample is not a violation, but it's the kind of number a carbon filter is sized against. For a leak at the curb or in the street, call your water supplier. For anything on your side of the meter, call us.

Permits.

University Gardens is an unincorporated hamlet, so plumbing permits go through the Town of North Hempstead Building Department.
