Why Do Portland Businesses Need Landscape Maintenance?

How does property grounds care include stormwater facilities?

On many Portland commercial sites, property grounds care has to include the swales, rain gardens and planters built to handle stormwater. However, these aren’t just landscaping. They’re permitted facilities with maintenance rules.

Portland City Code requires owners of sites covered by the Stormwater Management Manual to file an operations and maintenance plan for their stormwater facilities. In addition, the same code makes it a violation to remove or change a facility without approval from Environmental Services.

So, who maintains stormwater swales on commercial property in Portland? In most cases, the property owner does, often through their landscape contractor. Typical tasks include:

• Clearing leaves and sediment from inlets and overflows
• Weeding by hand, since many facilities limit chemical use
• Replacing dead plants with species suited to the facility
• Checking for ponding that lasts too long after rain
• Keeping a maintenance log, as many O&M plans require

Because they look like ordinary beds, unfamiliar crews can easily damage them, such as by filling a swale with bark mulch, thereby defeating its purpose.

Why do street trees need special handling in Portland?

Street trees in Portland require a permit for pruning even if the tree is the responsibility of the adjacent property owner, such as a commercial business. For example, many businesses have trees in the strip between the sidewalk and the street.

People often ask do you need a permit to prune street trees in Portland. Yes. The city says a permit is required to prune any tree in the right-of-way, and all work must meet its street tree pruning standards. For most routine pruning, the permit can be self-issued online, unless the tree is a Heritage Tree.

Here’s why that matters for maintenance:

• Only the adjacent owner or their designee can apply for the permit.
• Low branches over sidewalks can trigger a city notice to prune.
• Topping or heavy cuts can count as harm to a street tree.

A maintenance partner who handles permits keeps you out of trouble, while one who doesn’t can create a violation with a single visit.

What should a landscape maintenance contract plan for across Portland seasons?

A good landscape maintenance contract plans different work for each season, because Portland’s wet winters and dry summers need very different care. Here’s how the year usually breaks down:

Overall, fall is the busiest time of year for commercial sites. In fact, leaves fall from the trees and clog the walks, drains and even the stormwater facilities, sometimes within a week’s time.

Summers in Western Oregon, on the other hand, are dry, so irrigation failures can kill plantings quickly. For that reason, regular maintenance matters more than most owners expect.

How can property managers check that maintenance is being done right?

Property managers can check maintenance quality with regular site walks, visit reports and a few simple warning signs. After all, you shouldn’t have to guess whether the crew showed up or did the full scope.

Here’s what to look for:

• Visit reports listing what was done and anything that needs attention
• Quarterly site walks with your account manager to review problem areas
• Clean stormwater inlets after leaf season, not just tidy beds
• Healthy, edged beds without weeds creeping in between visits
• Irrigation that matches the season, not sprinklers running in the rain

Warning signs are just as useful. Mulch piled against tree trunks, shrubs sheared into tight balls and swales filled with bark all point to crews working fast instead of working right. If you notice these, raise them early, because poor habits tend to repeat on every visit.

Finally, good communication matters too. One named contact who knows your site will catch small problems before tenants or city inspectors do.
