Most residential french drains and yard drainage in Cedar Rapids do not require a building permit, but stormwater management rules apply to larger projects. Check with the Building Services Department to confirm what your job needs.
The City of Cedar Rapids Building Services Department handles permits for construction work. For typical residential french drains and yard drainage fixes, you usually do not need a building permit. Small drainage projects like installing a perimeter drain, adding catch basins, or extending downspouts generally fall under maintenance and minor grading work.
However, if your drainage work involves major grading that changes the slope of your lot, construction of retaining walls, or installation of stormwater management systems as part of new construction or an addition, you may need a permit. Retaining walls require a permit and the fee is $25. Any work that affects how stormwater flows off your property or into city storm sewers may require review under the stormwater ordinance.
If you are not sure whether your project needs a permit, call the Building Services Department at 319-286-5831 before you start work. You can also email questions to residential@cedar-rapids.org for residential projects. It is better to check first than to find out later that you needed approval.
Cedar Rapids has a stormwater management ordinance in Chapter 72 of the Municipal Code. The city operates under a Municipal Separate Storm Sewer System permit from the Iowa Department of Natural Resources. The stormwater system collects surface flow through storm drains, pipes, and ditches and discharges it to the Cedar River without treatment.
For most single-family home drainage projects, the stormwater ordinance does not add extra permitting steps. The rules mainly apply to new development, subdivisions, and larger construction sites that disturb more than one acre. However, all property owners are responsible for managing stormwater on their own land. You cannot direct your drainage in a way that harms neighboring properties or dumps pollutants into the storm sewer.
If you have questions about stormwater rules or runoff, contact the Public Works Department at 319-286-5604 or email sewer@cedar-rapids.org. The city also runs a stormwater pollution hotline at 319-286-5815 if you see drainage problems or illegal dumping into storm drains.
When you install a french drain or regrade your yard, you need to keep water on your own property or direct it to an approved discharge point. The accepted standard is a slope of at least six inches of fall over the first ten feet away from your foundation. This keeps water moving away from the house instead of pooling against the basement wall.
You cannot grade your lot in a way that sends water onto your neighbor's property. If your french drain discharges at the edge of your lot, make sure the water flows to the street, a ditch, or a natural drainage path, not across someone else's yard. If you need to connect to a city storm sewer, that may require coordination with the Public Works Department.
Most residential drainage work stays within your property lines and does not require a formal site plan, but contractors should know these rules. If your project involves filling, grading near a property line, or significant changes to drainage flow, check with Building Services or Public Works to confirm you are following city requirements.
If your drainage project requires a permit, you will need to complete a building permit application and submit it by email, mail, or through the online system. The Building Services Department prefers electronic submittals sent to residential@cedar-rapids.org. The office is located at 500 15th Avenue SW, Cedar Rapids, IA 52404, and the phone number is 319-286-5939.
The application asks for a description of the work, the location of the work on your property, and dimensions to property lines if applicable. For larger projects, you may need to include a site plan showing existing structures, the proposed drainage system, and how water will be managed. Plans larger than 11x17 are not accepted for hard copy submittals.
Permit fees depend on the type of work. Retaining walls are $25. Other permits are based on the cost of construction. After the permit is issued, you will need to schedule inspections by calling 319-286-5831. Inspections should be requested the business day before you need them, before 4:00 PM. Make sure your contractor knows that final inspections are required before the work is considered complete.
Cedar Rapids has extensive floodplain areas because of the Cedar River and the major floods in 2008 and 2016. If your property is in a mapped floodplain, additional rules may apply to grading and drainage work. The city maintains floodplain maps and regulations to reduce flood damage and keep the stormwater system working.
Check whether your property is in the floodplain before starting drainage work. If it is, contact Building Services or the Development Services Department to ask what restrictions apply. Some work in the floodplain requires a floodplain permit, which takes about 15 days to review. You can find floodplain information on the city website at cedar-rapids.org or by calling 319-286-5831. Because Cedar Rapids has dealt with repeated flooding, the city takes floodplain rules seriously and enforces them to protect residents and infrastructure.
