Stormwater Grant Eligible Practices

Preventative Measures

Small, landscaped depressions that are filled a mix of native soil and compost and planted with trees, shrubs, and other garden-like vegetation
Designed to temporarily store stormwater runoff from rooftops, driveways, patios, and other areas around your home while reducing runoff rates and pollutant loads in your local watershed
Adds beauty and function to your landscape
Typically used in areas that drain 5,000 square feet or less

Rain gardens but with underdrain systems and engineered soils (comprised of mainly sand mixed with compost and top soil)
Typically used on properties with larger drainage areas (more than 5,000 square feet)
Found in non-residential settings like parks and commercial parking lots
Helps reduce runoff by soaking up excess rainwater using plants

Store rainwater for later use
Collects rainwater from a downspout system, screened to remove trash and leaves, and conveyed to a storage container for subsequent use
Stored rainwater is for non-potable water use only
Can provide significant reductions in storm water runoff rates, volumes, and pollutant loads from residential sites
Rain barrels may be part of an overall stormwater management system however, they typically do not provide enough volume alone

Can discharge directly onto driveways, sidewalks, parking lots, or other impervious surfaces
Disconnecting downspouts involves redirecting these flows onto lawns, planting beds, or other pervious surfaces
Reduce runoff by allowing roof water to infiltrate into the native soils instead of rushing into local streams

Shallow trench excavations filled with stone that are designed to intercept and temporarily store stormwater runoff until it infiltrates into the soil
Can provide significant reductions in stormwater runoff and pollutant loads
Well-suited to receive rooftop runoff and can be used to receive stormwater runoff from other small impervious areas
For residential applications, a Modified French Drain must be daylighted at its end to allow for overflow of larger storms

Comprised of seepage tanks set in the ground and surrounded with stone that are design to intercept and temporarily store stormwater runoff until it infiltrates into the surrounding soil
Well-suites to receive rooftop runoff entering the tank via an inlet grate (shown right) or a direct downspout connection
When properly sized and installed, dry wells can provide significant reductions in stormwater runoff and pollutant loads

Removing existing impervious surfaces (patios, tennis courts, decks, etc.) and replaving these areas with landscaped beds or lawn
Allows for rainwater to soak into the ground which reduces the amount of stormwater runoff from the property
Swimming pool removal is not eligible

Can be used in certain circumstances to reduce the amount of runoff from a property by adding or replacing existing concrete or other impervious surfaces with permeable pavers, porous concrete, or other practices that allow for water to soak into the soils below
Works best in flatter areas

Vegetated areas next to creeks and streams that help prevent channel erosion and improve water quality
Act as a filter for the surrounding area
Involves replacing lawn with deep-rooted trees, shrubs, and ground cover typically found on a native streambank
Grassed lawns within buffers provide very little structural support for stream banks due to shallow roots, and usually result in erosion that can eat away at backyards
Lawns can also contribute to water quality issues due to runoff or fertilizers, pesticides, herbicides, and pet waste

Pet waste is a major contributor to impaired water quality in streams
City seeks to install additional pet waste stations that can be publicly accessed and maintained

Common in developed areas and prevalent on properties without a healthy stream buffer
The more dense the natural vegetation is next yo your stream, the less erosion you’ll see within the channel
During winter, cuttings from trees that thrive in wet conditions (ex: willows, silky dogwood, elderberry, etc.) can be driven into eroding stream banks and within a couple years will grow into trees with roots that will help to prevent future erosion
In some scenarios, rip rap (large granite rock) may be used in conjunction with live stake pkanting, which helps to protect the live stakes while they take root
Rip rap used alone (without planting) can be effective but may also worsen channel erosion or wash away during heavy rain events

Can occur downstream of a stormwater pipe system
Eroded ditches can get worse with each major rain event, depositing large amounts of sediment downstream and potentially impacting the pipe system; these areas typically are located on properties and in hard-to- reach areas, making it difficult for one property owner to manage repairs
Effective ways of reducing erosion in these drainage easements include:

backfilling eroded areas with soil and using reinforcement matting and blankets to establish vegetation
using rip rap to fill in the eroded areas to prevent future scouring
extending the pipe system and stabilizing the new end of pipe
