Problem

Stormwater runoff collects everything in its path and carries it to the creek. Fertilizer runoff from yards and other landscaped areas is a major source of nitrogen and phosphorus pollution in our creek. Excessive nitrogen and phosphorus contribute to harmful, even toxic, algae growth in downstream water, which is dangerous to aquatic life and to us.

Solution

Having some lawn can help manage stormwater by allowing some stormwater infiltration, especially if you combine this with a downspout disconnection. Keeping your grass to around three inches tall helps reduce water use and protects the soil. Often, unhealthy soil is the problem, so testing your soil and building a healthier soil can help get your lawn off drugs. But, if you must to fertilize, keep the stream in mind and: use as little fertilizer as possible, don’t fertilize before a big rain, don’t get fertilizer on the street, sidewalk, or driveway because it will wash into the creek.
