Antelope Park Sub-Basin Water Quality Project

Program Overview

Due to stormwater runoff, many pollutants typical in urban areas have been found in Antelope Creek and its tributaries. The entire City benefits when residents take steps to keep stormwater from flowing directly into storm drains. Allowing stormwater to soak into the ground provides a natural filter to break down pollutants.

In 2014, residents within the Antelope Park Sub-Basin (a sub-basin of the Antelope Creek Watershed) could apply for a cost-sharing program sponsored by the Watershed Management Division. Qualifying property owners could be reimbursed for 75% of eligible expenses, up to a max share of $2000 per property.

Reimbursable Project Expenses

  • Soil amendments
  • Soil testing
  • Mulch
  • Native or hardy plants
  • Gutter, drain tile or stone used to convey water to garden
  • Equipment rentals
  • Design and construction labor performed by a landscape professional


  • Property must be within the Antelope Park Sub-Basin.
  • The property owner must submit an application and schedule a site visit before any work is started.
  • Upon completion of the project, the owner will pay all expenses and then assemble receipts for reimbursable items.
  • The property owner maintains the project

Projects Included

Rain Garden

A garden of native shrubs, perennials, and flowers planted in a small depression, which is generally formed on a natural slope. It is designed to temporarily hold and soak in rain water runoff. It is dry most of the time and typically holds water during and following a rain event.

Runoff Redirection

Driveway and parking lot runoff to storm drain inlets can be redirected to flow to rain gardens or other vegetated surfaces. This will treat and reduce runoff from the site improving water quality.

Lawn Seeding

Reseeding lawn turf to low-growing grasses that provides deep fibrous root system that will help build and maintain soil quality. They are hardy and will stay greener with less maintenance.

Downspout Redirection

During a heavy rain storm, each downspout discharges a significant amount of water. Some downspouts send rainwater down driveways, sidewalks, and underground pipes that lead to storm drains. Redirecting the downspout and allowing the rain water to flow across the lawn or into a garden provides more opportunity for rainwater to soak into the soil.

Pavement Removal

Hard surfaces serve as a pollution gateway to our waterway. These impervious surfaces prevent rainwater from soaking into the ground and recharging groundwater supplies. Paved surfaces also add to heat island effect, the phenomenon where urban areas are hotter than surrounding, non-urban areas. After hardscape removal, parking strips or pervious pavement may be placed to allow parking. To qualify for financial reimbursement, the soils under your hardscape will need to be amended.

Rain Barrel

If participating in any projects, residents will also be reimbursed up to $100 for a rain barrel. Barrels store rain water that is free of chlorine, fluoride, salts, and other minerals found in tap water. A rain barrel will save water for dry spells while reducing runoff and stormwater pollution. Use of a rain barrel can reduce your water bill, especially in the summer.
