KEARNEY STORMWATER MANAGEMENT PLAN
“I cannot stress it enough: all residents must save water and use less than 87 litres (23 gallons) per day.” – Patricia de Lille, Mayor, Capetown, South Africa
Three consecutive years of drought have brought Capetown, South Africa to the end of it’s water supply. All taps serving the city’s 3.74 million residents will be shut off April 21 – “Day Zero” – when the water is gone. Should the taps be turned off, each resident will be allocated 6.5 gallons of drinking water per day shipped from neighboring provinces.
The average U.S. resident uses 100 gallons per day – 4 times the current recommended use for Capetonians. How much more could we conserve?

Trees play a critical role in managing our city’s stormwater runoff. Enjoy this interactive poster from the Arbor Day Foundation highlighting the role trees play in urban stormwater management.
Falling leaves signal the official arrival of Autumn. Put leaves to good use as insulating mulch in a garden bed, make them into compost, or shred them across the lawn as a natural fertilizer. Left to lie in gutters, leaves quickly clog storm drains leading to flooding in a Fall storm and nutrient pollution as the leaves degrade in the storm sewer. Pile ’em up and enjoy the benefits of leaves next spring!
For many people, taking care of the environment is common sense. It’s also required by law.
Scottsbluff operates under the National Pollution Discharge and Elimination System (NPDES) Phase II Municipal Separate Storm Sewer (MS4) General Permit. The permit
encompasses six general areas:
– Public Education and Outreach
– Public Involvement
– Illicit Discharge, Detection and Elimination
– Construction Stormwater
– Post-construction Stormwater
– Good Housekeeping/Pollution Prevention for Municipalities
The city’s stormwater surcharge not only pays for MS4 infrastructure but also the programming that educates residents and become active in pollution prevention and preserving water quality.

Permeable pavement allows water to pass through the surface into the ground generating more groundwater recharge, faster melting of ice and snow, and decreasing the amount of water runoff from a property. Porous concrete, porous asphalt, or interlocking pavers are also good for trees whose roots can access the air and water that flow through the pavers.

Heat generated from bacteria causes the compost pile to stay warm and active, no matter which season you’re in. Ideally, new material should be added to the composting system during turning and mixing to keep the pile the most active.

FROM THIS…………………………..TO THIS
Stormwater runoff comes from precipitation events and when snow/ice melts onto impervious surfaces. An inch of rain on an acre of land is equivalent to 27,154 gallons of water with a weight of 113 tons. This water transports many pollutants, including but not limited to sediment, oil, grease, fertilizers, bacteria from pet waste, and litter/trash. Stormwater DOES NOT get treated prior to being flushed into waterways.
It’s nearly July and the gardens are green and full of early summer blossoms – using just rainwater.
Late last week the City of Scottsbluff finally turned the water on the downtown gardens, about three months after lawn watering began around the city. Native and well adapted plants use much less water than traditional turf once established. They’re also drought hardy, provide needed habitat for pollinators and create a distinct sense of place with a plant palate tailored for the Nebraska Panhandle.
Nebraska is home of Arbor Day, which we celebrate this Friday. See just how much work trees do!
