Lakewood, Echo Valley and Newer Norwalk, IA Homes
Settlers reached the Norwalk, IA area about 1846, and Samuel Snyder's log cabin was its first building. The post office dates from June 18, 1856, and the town incorporated in 1900 under first mayor Adam Stiffler. Lakewood began in 1965 around man-made Lake Colchester and Echo Valley in the early 1970s, home to some of the city's 1960s and 1970s houses.
Census survey data place the typical home at about 2002. About 10% of the 5,820 homes predate 1960, 10% are from the 1970s and 12% from the 1980s, while the 2010s alone added about 27%. About 73% are single-family detached, about 83% owner-occupied, and the median value is $303,100.
Newer basements still take on water: tile fills with silt, a pump quits or lags behind a downpour, and backfill sinks until the yard tilts toward the house.
How Each Service Fits Norwalk, IA
- Sump pit and pump. Typical work is a stronger pump, a check valve, an alarm or a battery backup.
- Perimeter drain tile. Tile laid inside along the footing moves water under the slab to the pit.
- Wall cracks. Poured walls can usually be injected; a crack that keeps opening deserves a look.
- Window wells. A well that holds water needs a working drain and a cover; resizing an egress window takes a permit from the city.

Norwalk, IA's Foundation-Drain Rule After 2008
The spring 2008 floods led the City of Norwalk, IA to create a Foundation Drain Removal Program. Inspectors went through the city one district at a time, looking for perimeter drains and sump pumps that emptied into the sanitary sewer. Some older homes had been built that way, City code counted those hookups as illegal connections, and owners could get some help paying for corrections.
Whether it still runs couldn't be confirmed; the Building Department, (515) 981-9530, takes questions about the rule. Unhooking a sump or footing drain from the sanitary sewer belongs to a state-licensed plumber under a plumbing permit. Sump water should land outdoors.
Floods here go back further: the first railroad, built in 1882, was given up in 1947 after high water wrecked much of its North River bridge. On July 20–21, 2026, the National Weather Service reported 4 to 6 inches "around and within the Des Moines metro."
Who Handles Sewers and Permits in Norwalk, IA
Public Works in Norwalk, IA has its own wastewater and sanitary collection crew. For a backup, contact it at 515-981-9527; after hours, the City lists 515-222-3321. Water coming up a floor drain is a sewer matter that waterproofing won't stop.
Permits go through the Building Department (Community Development), (515) 981-9530, 705 North Ave. Its list includes plumbing permits and an egress-window permit whenever the window size changes. Sump pits, drain tile and waterproofing aren't on it, so ask up front which permits apply and whose name goes on each.

Quick Answers for Norwalk, IA
Is Norwalk, IA's foundation-drain program still running?
That couldn't be confirmed. After 2008 the City inspected homes district by district and helped some owners with correction costs; whether any help remains is unknown. The Building Department, (515) 981-9530, can answer questions about your house.
Where should my sump pump discharge?
Outdoors, clear of the foundation and the neighbors. The City's code treats perimeter-drain and sump hookups to the sanitary sewer as illegal, so never a floor drain, laundry tub or sewer pipe. If unsure, ask the Building Department or a state-licensed plumber.
Does enlarging a basement window need a permit?
In Norwalk, IA, yes: changing an egress window's size requires a permit from the Building Department at 705 North Ave. Ask for that permit to appear in the written estimate.
Can I change my mind after signing at home?
Generally, a deal of $25 or more made somewhere other than the seller's business may be cancelled until midnight of the third business day under Iowa's door-to-door rule. Whether that reaches a visit you requested is unsettled, so cancel in writing and keep a copy.
