On April 1, 1989, the neighborhoods of Lakewood and Echo Valley Estates were annexed into Norwalk. The original Lakewood development was started in 1965 around the man-made Lake Colchester. The south shore of the lake is home to nearly 600 residences and the north side is being heavily marketed for its future development potential with planning in place for 1,000 plus housing units. The south side of the lake also contains the Lakewood Elementary School.

Echo Valley
The Echo Valley development began in the early 1970s, consisting primarily of residential properties intermixed with the Echo Valley Country Club golf course. Generally considered one of the more upscale areas of town, Echo Valley has hosted the Home Builders Association of Greater Des Moines' Home Show Expo twice in the 2010s.

The Legacy
The Legacy golf course community incorporating what used to be called the Colonial Meadows development, contains 18 PGA caliber golf holes, over 900 residences suitable to a wide range of housing budgets, and an increasing variety of commercial opportunities for what has become the geographic center of the City. The development incorporates commercial development along Iowa Highway 28 and a regionally-unique circular central road which will be completed in 2018.

Windflower, Brody's Landing, Rolling Green, and Warrior Run
The southeast portion of the City contains the Warrior Run golf course as well as several residential developments that will add hundreds of housing units to the City. Windflower and Rolling Green are the more established neighborhoods with the Warrior Run Estates and Brody's Landing continuing to add housing options to this area of town. The campus for Norwalk High School and Norwalk Middle School is also located in the neighborhood, just south of North Avenue.

Timber View, Timber Ridge, Silverado, and Blooming Heights
The western portion of the City has seen increased growth in recent years with the emergence of these four neighborhoods of about 450 homes. Located along G14 and 50th Avenue, they provide excellent access to the Des Moines metro while remaining nearby the increasing opportunities within Norwalk.

Holland Pointe
Just south of Beardsley Street across from Echo Valley is a new Hubbell development titled Holland Pointe. The neighborhood is an active living community with trails and a variety of housing options. The development is flagged by Elizabeth Holland Park to the west. The neighborhood will provide a variety of housing options, from single family homes, townhomes, and apartments, that will provide options for residents to upsize and downsize their home while staying in the Norwalk community.

Hughes Century Crossing
Situated just southeast of the new Norwalk Central concept, Hughes Century Crossing offers smaller lot single family residential and townhome units that will be within walking distance of the new recreation/commercial center.

Sunset Estates and Shadow Creek Estates
Recent investment in sanitary sewer has made the area surrounding the Legacy ripe for future growth. To the north of The Legacy is Shadow Creek Estates, which combines traditional single family lots with a complimentary townhome development. To the south of Legacy is Sunset Estates, a more traditional single family neighborhood that will provide a variety of lots sizes for future residents.

Orchard Hills and Valley View
On the south side of town is the Orchard Hill neighborhood that consists of primarily single family homes with a few townhome and duplex areas. The Orchard Hills Elementary school is just to the west on North Avenue and the McAnninch Sports Complex borders the south of the neighborhood. Just to the southwest, the Valley View subdivision provides more single family homes, duplexes, and park space.

Founder's District and Norwalk Knolls
This area encompasses some of the original development in the City and some of the City's oldest homes. The Oviatt Elementary School resides in the center of the Founder's District, which also includes the North and Main Street area with several restaurants and other businesses.
