Planting Strip Gardens in Seattle

For someone who spent their childhood surrounded by natural beauty and later migrated to a city as lush as Seattle, the idea of transforming the humble planting strip—the patch of ground between the sidewalk and the street—into a thriving green space is irresistible. Here at Happy Garden Projects, we see these often-overlooked ribbons of land as blank canvases primed for ecological artistry.

Seattle residents have discovered that cultivating these strips enhances curb appeal, attracts pollinators, and even offers more room for those who like getting their hands dirty with edibles and herbs. Importantly, before you begin dreaming of bee balm and Oregon holly-grape, the city requires gardeners to get a free Street Use permit. The effort is well worth it, especially when your patch produces color, fragrance, and a natural buffer from the urban hum.

Before any digging, it’s critical to confirm the absence of underground utilities—simply call 811 to have a map drawn up for free. Once you’ve secured the all-clear, let your imagination (and responsible planning) roam: perennials, native grasses, low shrubs, and edible plantings are all encouraged, provided they don’t obstruct walkways or drivers’ sightlines.

Seattle specifically champions native and drought-tolerant plants. Some favorites include wild ginger and shore juniper as groundcovers, or Pacific coast iris and lady fern for seasonal highlights. If you have space for shrubs, look into snowberry and dwarf olive, which are as functional as they are beautiful. A well-chosen palette will not only support wildlife but make maintenance easier year-round.

Permits and Planning: The Essentials

The process to get your garden growing starts with a solid site plan. Your drawing must detail plant placements and confirm that your design keeps sightlines clear and walkways accessible. Templates are available to make drafting a breeze, even if you’re more of a green thumb than a draftsman.

Submitting your application is straightforward through the Seattle Services Portal. Just select the "Gardening/Planting" permit type after logging in. If this sounds intimidating, support is available from real humans—either virtually or over the phone—to guide gardeners through each step.

Here’s a quick reference table to help keep things organized:

Task Action
Check for Utilities Call 811 before digging
Choose Plants Prioritize native/drought-tolerant varieties
Draw and Upload Plan Use the site plan templates and upload to portal
Apply for Permit Use Seattle Services Portal (it's free!)

Community, Beauty, and Ecology

It’s heartening to see so many neighbors embracing the right-of-way planting opportunity. Beyond personal satisfaction, these collective efforts buffer stormwater runoff, enhance safety for pedestrians, and foster biodiversity across the city streetscape.

If you’re looking for more of a collaborative experience, Seattle’s P-Patch community gardens or neighborhood volunteer days are excellent next steps. With every new planting strip garden, we edge a little closer to the vision of Seattle as a city where nature flourishes in harmony with urban life.
