Structures, Tools, and Resources

Growing food takes more than seeds and soil. It takes tools, space, water, and knowledge of what’s available and allowed in the City.

This section looks at structures, tools and resources such as what events, workshops, services, and organizations are available to help you; where to find tools and resources to fit your needs and budget, and current applicable ordinances in Des Moines.


Greenhouses, Sheds and other Accessory Buildings Back to Top

It's a fact of life, Iowa has winters during which many foods cannot be grown. To extend the growing season, temporary and permanent structures can be useful to start growing food in early spring or continue into late fall. Greenhouses are often permanent structures with a solid floor or foundation. Hoophouses tend to be more seasonal and temporary with dirt floors for direct sowing of crops.

Other structures you may want to use include pens and buildings for animals, storage buildings for tools, structures for shade, rainwater capture systems, and compost bins or containers.

When it comes to regulation, the Des Moines Zoning Code doesn't specifically refer to greenhouses or hoophouses. Currently, any permanent non-residential building on an individual lot would be regulated as an accessory building and built to the appropriate standard for snow load and wind resistance.

Fencing

Fencing in urban farming serves multiple purposes:

  • Keep animals out (dogs, deer, rabbits) or keep animals in (poultry, goats, small livestock)
    • Consideration: Bury fence at least 6 inches deep to keep rabbits and other animals from digging under fence.
  • Can be used to define a space
  • Useful for privacy and/or hiding unsightly areas from public view

While fencing is optional for residential uses, a perimeter fence is mandatory for community gardens (see section 134-3.7(G) of Des Moines building code).

Here's a summary of what the zoning regulations include regarding fencing:

  • Allowed? - Yes, fencing is allowed in all residential districts

Any use designated as a community garden must have a fenced perimeter (134-3.7(G))

Irrigation

As Iowa’s climate continues to change, the trend is projected for wet springs and dry summers with intermittent intensive storms in between. To keep your garden produce alive during the summer, it may be necessary to water on a regular basis.

During dry periods, pay attention and follow any recommendations from Des Moines Water Works on when and how to water your property. There may be restrictions as to how much and how often you can water.

In general the City asks you follow the Des Moines Water Works “Use Water Wisely” Recommendations:

  • No irrigating on Mondays
  • Even numbered addresses (Ex: 120 Main Street) should water on Sundays, Wednesdays and Fridays, before 10 a.m. or after 5 p.m.
  • Odd numbered addresses (Ex: 123 Main Street) should water on Tuesdays, Thursdays and Saturdays, before 10 a.m. or after 5 p.m.
  • No irrigating during the hottest part of the day between 10 a.m. and 5 p.m.
  • Ensure outdoor garden hoses and spigots do not have leaks, and water is not left running when not in immediate use

Additionally, deep watering encourages deeper and stronger root growth. Therefore, watering gardens about 2 inches (5 cm.) or so once a week is preferable. Watering more often, but less deep, only leads to weaker root growth and evaporation. Watering during the daytime can also lead to the sun burning leaves with water drops on them.

Watering technology that most people are familiar with includes sprinklers that can remain in place and often rotate or swivel to cover a swath of your garden for a period of time. They come in a variety of styles and costs and can be easily found at a neighborhood hardware or lawn & garden store. They may come with a timer or you may have to set your own. The advantage is you can put it in place and walk away. One can also water with hoses and a spray nozzle, the drawback being someone needs to take the time to stand and spray the garden for a length of time. For small pocket gardens, a watering can can be a sufficient tool for watering specific plants individually. You will probably want all of these tools at different times during the growing seasons.

Drip Irrigation

For the Urban Gardener who is farming a large plot of ground, drip irrigation is a good way to use water wisely. Drip irrigation hoses lay on the garden and have small holes throughout that allow the water to drip directly into the ground, eliminating overspray and evaporation to a large extent, and getting the water directly to the roots of your plants. If your intent is to farm a large area of ground, investing in drip irrigation, though pricey up front, can save you in water costs in the long run and worth the upfront cost of investment.

Drip irrigation hoses can be purchased at most Lawn and Garden shops, neighborhood hardware stores and online.

Rainwater Collection Systems

One way to save on water costs is to create a Rainwater Collection System. This can be done with the purchase of one or more rain barrels connected to a property’s gutter system. There was a time when below-ground cistern systems were popular, though it is rare to see them implemented these days. If you’re working on a property that doesn’t have any buildings or water access, creating a shelter for worker shade that has a gutter and rain barrel system may be an option too.

The City encourages rainwater collection as part of a Stormwater Best Management Practices program called The Rain Campaign in an effort to reduce stormwater runoff and erosion from entering our streams and drinking water system. The City will reimburse property owners 50% of the total cost of their project, up to a limit of $2000, provided the project and property owner meet the requirements of the program. Learn more about the City of Des Moines Stormwater Subsidy Program (rain barrel cost share).

Water access – Hydrant meter

When alternate sources of water supply are not available, Des Moines Water Works issues hydrant meters to qualified contractors or civic organizations. Meters are issued for a specified time period not to exceed eight months. All hydrant meters issues shall be used only at the location specified on the application and may not be moved without permission from DMWW.

  • Available to Civic and community organizations
  • $670 deposit; refundable
  • Needs to be self installed
  • $30.00 mo/plus use

There is a limited supply of hydrant meters, and they are issued on a first-come, first-serve basis. City, County, and State projects are given higher priority. For more information see, visit Waterworks Hydrant Meter Rental (for civic organizations).

Sec. 135-2.22.4. — Accessory Utility Structures

  1. Cistern and Rainwater Collection System
    1. A rainwater collection system is exempted from inclusion in the site impervious area calculation.
    2. Below ground systems may be located in any yard.
