WATER STEWARDSHIP AT HOME

Residents can help support lakes, wetlands, and streams right from home. Check out these tips and resources to help plan ahead, beautify the yard, and reduce overall maintenance time. We've outlined four goals for residential yard care:

Reduce runoff volume

The introduction of pavement, rooftops, and other impermeable surfaces creates new challenges and shortcuts in the water cycle. The more water travels, the more it picks up contaminants and debris, and the less it replenishes groundwater. A single family home can generate thousands of gallons of runoff each year, but by catching water where it falls, we can reduce stress on lakes, streams, and wetlands. 

Downspouts: Direct downspouts into grassy areas instead of onto pavement. This can be an easy fix in areas with no basement, or could mean extending a downspout. 10' is the recommended distance between a drainage point and a home foundation. 

Store water closer to where it falls: Consider installing a raingarden, bioswale, or permeable pavement to retain runoff, infiltrate it into the ground, and help reduce drainage burdens for a downstream neighbor. These projects are designed to hold water up to 48 hours - a valuable timeframe for water retention and not enough time for ponding or mosquito propagation. In many cases, creating space for water to infiltrate is both an asset to the watershed and a way to consolidate and control wet problem areas. Visit our grant programs page to learn how VLAWMO can help fund a project on your property. 

 

Reduce nutrients in runoff

Excess nutrients is one of the main causes of poor water quality in the metro, causing strong algae blooms, murky water, and degraded aquatic habitat. To keep excess nutrients out of lakes and wetlands, we must help them stay up on the landscape. 

Grass clippings: Direct grass clippings away from the street. This can easily be accomplished by keeping the spray side of the mower (typically the right side) pointing away from pavement for 2-3 passes around the perimeter. Mulch grass clippings into the lawn for free fertilizer, or dispose of them at a designated yard waste compost site or through a yard waste curb side hauler service. 

Clean pavement: Sweep or use a blower to keep leaves and grass clippings out of the street and off of pavement. Grass clippings and mulched leaves act as free fertilizer when left on the lawn.

Wash smart: Home car washes are convenient, but send soap, oil, salt, and excess mud to a lake or wetland. Visiting a commercial car wash helps by sending the dirty wash water to a treatment plant. When cars or trucks are especially muddy and need heavy washing, doing so on the lawn or using rolled-up towels across the driveway are easy ways to reduce debris going into runoff. Be sure to fix automotive leaks promptly, as these also wash into waterbodies with stormwater.  

Fertilize smart: Fertilize according to a professional soil test. If you must fertilize, do so in the early fall. At this time grass is avidly gathering nutrients to store for winter. This helps reduce the amount of fertilizer that runs off the lawn. Avoid weed-and-feed mixes, as these tend to increase runoff of fertilizer and herbicide, striving for convenience rather than the specific needs of the lawn and soil. Select a slow-release fertilizer to help keep the application on the soil where its intended. Leaving grass clippings on the lawn also serves as a fertilizer - one year's worth of grass clippings is estimated to be about the same as a single application of synthetic fertilizer. 

Dispose yard waste responsibly: Avoid dumping yard waste such as leaves and grass clippings into ditches and wetlands. Although they're natural material and seem innocent, grass clippings, leaves, and yard waste become pollutants in water bodies. Dumping into ditches and wetlands clogs drainage ways, encourages algae blooms, smothers plant life that would otherwise assist soil and water health, and creates a need for expensive dredging. Instead, dispose of yard waste through a licensed hauler service or at a designated county compost facility. Dumping any material into a storm drain is an illegal illicit discharge

Pick-up pet waste: Although seemingly innocent and minuscule, both the Environmental Protection Agency (EPA) and the Minnesota Pollution control Acency (MPCA) have placed pet waste in the same category of water contaminants as toxic chemicals and oil. Because dogs are so abundant in urban and suburban areas, there's a higher density of waste to recon with. According to the EPA, the average dog discards about three quarters of a pound of waste per day. With this, 100 average sized dogs can produce up to 75 lbs of waste annually, 2,250 monthly, and 27,000 lbs annually. Pet diets are also high in protein, unlike geese and deer, which leads to a very potent poo. Beyond nutrients, pet waste also carries coliform bacteria, ringworm, roundworm, salmonella, giardia, and other contaminants. While wildlife waste also carries bacteria, the added density and abundance of pet waste is a strain on local surface waters and exacerbates the risks posed to pets and humans. Pet waste can take up to a year to fully break down, continually sending contaminants into storm drains and ditches via runoff and snowmelt. Parks and yards with turf grass and compacted soil are more conducive to shedding runoff and picking-up contaminants. Because these contaminants and the risks they pose to freshwater and people are avoidable, picking-up pet waste promptly is the responsible choice. 

 

Reduce erosion and sedimentation

Reduce erosion and sedimentation:

Sand and soil particles are constantly on the move. As the landscape changes though, the rate at which soil moves can increase, and the end destination is usually a water body. Faster runoff can lead to increased erosion. By covering bare soil and maintaining healthy upland vegetation, we can prevent water from picking up speed, and prevent water bodies from being choked out with sediment. This also helps keep ditches and storm drain systems functioning efficiently, and reduces the amount of contaminants that stick to sediment (oil, antifreeze, automotive brake dust, fertilizers, excess nutrients, etc.). To help reduce erosion and sedimentation into water bodies: 

Mowing height: Cut grass at a 3". This reduces erosion and evaporation on the lawn by allowing grass to shade the soil (reducing evaporation) and grow deeper, more stable roots. Deeper roots allow the soil to hold more water before it gets saturated, making more versatile to both wet and dry extremes.

Mowing light: Cut only 1/3 of the blade at a time. Even if the lawn was neglected for a time, cutting extra short to make up for lost time stresses the grass, making it more vulnerable to problems. 

Cover bare soil: Be attentive to bare soil and cover it quickly with sod, shrubs, or an arranged planting. When dried out from wind or sun exposure, it is more susceptible to erosion. 

Stabilize: Place boulders or trap rock in high velocity runoff areas. This slows down runoff and gives it time to soak into the ground, disperse, and reduce soil damage. Sometimes regrading a slope is needed. 

Try longer vegetation: Prior to European settlement,  perennial vegetation (prairie, wet meadow, marshes, etc.) worked as infrastructure for the water cycle. Prairie and wet meadows move water slowly, filter it, and store it to reduce downstream impacts. While traditional lawns and development have their advantages, VLAWMO strives to achieve clean water and storage benefits by also re-integrating perennial vegetation into our built community. Where feasible, features such as deep-rooted native plants, lo-mow lawns, ground covers, and prairie and shoreline restorations can be an asset to both homeowners and the watershed. Low traffic and hard to maintain places are often rich with other opportunities besides turf grass. Visit our cost-share web page to learn more about these types of projects and to get funding for a project of your own. Examples can be found on our our articles page. See the Blue Thumb link (right) for more on native plants.

Conserve water

Keep water off the pavement: Set sprinklers and irrigation systems so that they don't spray onto pavement. Fix errant sprinkler heads that are spraying onto pavement or contact an irrigation professional to request a fix. 

Timing: Water plants and grass early in the morning or in the evening to reduce evaporation.

Water just enough: Account for rainfall in weekly watering. According to the U of M, turf grass only needs 1" of water per week. When dormant, turf typically doesn't require any watering. In many cases, municipal odd/even watering bans encourage more watering than necessary due to the assumption that watering must occur on certain days. 

Shorter sessions: Divide typical lawn watering time in half, and water twice. Two short sessions prevent saturation, which causes less water to run off the lawn. A few hours between watering sessions helps the lawn hold water. For trees and shrubs, deeper watering sessions are recommended. 

Keep it on the down-low: Select sprinklers that reduce evaporation and wind drift. These are sprinklers that keep water low to the ground and disperse water in a stream rather than a mist.

Know when you're overboard: Watch for over-watering. Grass that's mushy underfoot, has a musty odor, or sprouts mushrooms, moss, or mold are signs of this issue. 

Stay sharp: Avoid a "set it and forget it" strategy. As seasons change, rain patterns change. Adjust irrigation systems weekly according to rainfall, and cut back on days of watering as temperatures decrease. Turf grass naturally goes dormant in the late summer; consider allowing a brown, dry look at this time and it will green up again when rain returns. Consider smart irrigation systems that account for rainfall and water at the best times of day automatically. 

Store and re-use: Install a rainbarrel to re-use rainwater on garden plants. VLAWMO will reimburse 50% of a rainbarrel for residents in the watershed - visit our grant programs to learn more.

  • Help prevent illicit discharge: Illicit discharge is anything that isn't stormwater or snow melt. Inform family and friends that it is illegal to use stormdrains and ditches as a waste receptacle, and call your City or Township's engineering or public works department to report a suspected illicit discharge. Learn more with this illicit discharge video
  • Adopt a stormdrain: Adopting one or several nearby stormdrains is an easy, practical way to make a difference for water quality. Visit adopt-a-drain.org to find your drain, give it a name, and get started with watershed protection.

  • Adopt a raingarden: For garden and outdoor enthusiasts, helping maintain a public raingarden keeps our projects functioning and looking great for the community. Each raingarden or bioswale has a team of volunteers, and small, frequent maintenance is both more convenient and the most effective method of maintenance. Visit our service opportunities page to get plugged-in.

Water Stewardship in the Home

Water Stewardship in the Home:

Use the fridge: Keep a pitcher of water in the refrigerator to reduce run time as water gets cold. 

Fix leaks: Leaky sinks, toilets, and pipes can waste up to 90 gallons of water each day. 

On/off control: Keep water off when brushing teeth, use when needed. 

Dishes: Only run a full load of dishes. Skipping the extra rinse is often adequate and saves water.

Simple tools: Install faucet aerators and low-flow shower heads.

Shop smart: Watch for the WaterSense logo when purchasing devices and home appliances. 

Learn about salt and softening: Visit the MPCA Water Softening page for tips on how to manage your home water softener with water quality in mind. Small amounts of leftover water softening salt should be disposed of in the trash. Visit Ramsey County's disposal guide for more on water softeners: Water Softeners.

Illicit Discharge/ Illegal Dumping

Illicit Discharge is illegal dumping

The Cities and Townships in the VLAWMO watershed facilitate an illicit discharge detection and elimination (IDDE) program. An illicit discharge is any substance that's not stormwater or snow meltwater. The IDDE program strives to ensure that only stormwater and snow meltwater go into a stormdrain system or ditch drainage system. Because stormdrains and ditches send stormwater runoff and snowmelt directly to a receiving waterbody untreated, it's important to plan for proper disposal of chemicals, furniture, paints, and other household materials.

What should not go into stormdrains, ditches, or wetlands: 

  • Motor oil and grease
  • Construction material such as concrete or drywall debris
  • Water softener salts
  • Antifreeze
  • Cleaners, paints, and solvents
  • Furniture such as unwanted couches or mattresses
  • Grass clippings
  • Leaves and other yard debris
  • Scrap metal

These items harm our local wetlands, streams, and lakes, and cost taxpayers money for clean-up and remediation. Leaves and grass clippings are "natural," but when dumped into ditches or wetlands cause an excess of nutrients that feed algae blooms, create conditions that cater to undesired or invasive vegetation, hinder the efficient movement of water on the surface and into the soil, and cost taxpayers an extra burden for clean-up and maintenance.

What should go into stormdrains or ditches:

  • Stormwater runoff: "Only rain down the drain"
  • Snowmelt 

Smart Planning for Responsible Disposal: 

In many cases, the responsible choice for material disposals isn't an instant result. Because of this, a bit of patience and some work to be familiar with the processes on the front end before the need to dispose of something arises is paramount for protecting our water resources.
