1950s and 1960s Basements in Ralston, NE
Ralston is the smallest city on this site, with 6,382 residents (2025 Census estimate). The typical home among its 2,987 dates to about 1972, and census survey data show a long middle: about 6% from 1939 or earlier, 4% from the 1940s, 12% from the 1950s and 24% from the 1960s, so roughly 45% predate 1970. About 64% are detached houses, about 63% are owner-occupied, and the median value is $230,800.
These houses can sit on poured or block walls that have weathered six or seven decades. Not every Ralston home has a full basement; this page is for owners, landlords included, whose homes do.
George and Hariette Miller are considered the founders. The townsite dates from May 23, 1907, when it was called Seymour Park after Horatio Seymour, and a 1967 agreement let Ralston carry on without fear of annexation.
What Ralston, NE Homeowners Ask For
- Block wall seepage. Mid-century hollow block can take on water and leak along mortar lines; an interior drain to a sump is one common answer.
- Damp floor edges. Water where wall meets floor after a soaking rain often means wet soil pressing in. See basement drainage.
- A worn-out sump. A pump that runs nonstop or has quit may need replacing; its water should land outdoors, never in a floor drain or sewer line.
Water History in Ralston, NE
That 1892 well left behind today's Seymour Lake. Two city projects now tackle surface water: flood-control work on Ralston Creek from fall 2026, and Phase 1 of the Stormwater Improvement Project, adding or enlarging storm sewers in the Sunset and Belmont neighborhood from early 2027 to spring 2028 (public hearing August 18, 2026).
Both target streets and yards, not basements. Groundwater is its own problem: across eastern Nebraska, wind-blown loess over clayey glacial till can keep a foundation wall wet long after the rain ends, and drains, sumps and crack repair exist to manage that pressure.
Ralston, NE Permits, Plumbers and Sewer Questions
Permits run through City Hall, 5500 S. 77th St, 402-331-6677, with Building and Safety at ext. 1310. In the city's words, "Building permits are required for most projects", and applications go through its online Citizen Portal. Structural work may need one, plumbing or sewer work its own; the contractor confirms with the city what applies.
Plumbers working in Ralston need a master plumbing license from a metro city Ralston accepts, Omaha and Bellevue, NE among them, plus a certificate of insurance. That covers tying a sump into a pipe, a backwater valve or private sewer line repair.
Sewer questions and backups go to City Hall at the same number, and sanitary sewer improvements are planned alongside a street extension in 2027–28. A Ralston address uses Ralston's offices, not Omaha's.

Local Questions
Ralston borders Omaha on three sides. Whose rules apply to my house?
Ralston's, if the address is inside the city. Permits come from City Hall, and plumbers need a master license Ralston accepts. State law applies everywhere: Nebraska requires contractors to register with the Department of Labor, which you can check at dol.nebraska.gov or (402) 471-2239.
Will the stormwater project keep my basement dry?
It isn't designed to. Phase 1 adds or enlarges storm sewers to cut street and yard flooding in the Sunset and Belmont neighborhood. Seepage through basement walls comes from wet soil around the foundation, a separate matter for a waterproofing contractor.
Can the sump be connected to the sewer?
Sump water shouldn't go into a sewer line or floor drain at all; it belongs outdoors, away from the foundation and the neighbors. Any connection to a pipe is plumbing work under a permit, and City Hall or a licensed plumber can say where the discharge should go.
What belongs in the contract?
The Nebraska Attorney General advises putting it in writing: the work, materials, total price, finish date and the contractor's contact details. Agree on a reasonable down payment, pay the balance only when the work is done, skip cash and ask for lien waivers. If you sign at home, a three-business-day cancel window may apply. The Attorney General takes complaints at (800) 727-6432.
