Sustainability & Plantscaping

More Than Just a Pretty Place

Sustainability Features

  • Gutter directs stormwater runoff from 2/3 of city block into park, which during cloudbursts can temporarily transform much of the park into a lake
  • Curb cuts allow runoff to enter park
  • Public sidewalk width reduced and replaced with plant beds to decrease impervious surface area
  • Native plants flourish without water even during periods of drought
  • Wild prairie-cut buffalograss sod planted instead of lawn
  • Underground drainfield beneath main lawn collects & filters runoff
  • Off-grid solar overhead and path lights (LED; dark- sky)
  • Solar panels on shelter feed excess electricity into power company grid.
  • LED shelter lights motion activated. Park’s monthly electric bill less than $20.
  • River rock swales slow down and channel water through the park.
  • Retention pond collects and holds thousands of gallons of runoff.
  • Solar-powered water pump aids with evaporation & water quality.
  • Overflow from major event empties into raised drain which feeds into perforated drain tile that connects to stormwater sewer
  • Trees, bushes, plants & grasses absorb rainfall.
  • Installed beetle-kill paneling on shelter ceiling.
  • Park uses solar panels to generate electricity that charges batteries for the lawn mower, weed whacker and leaf blower.

Native Plantscaping Features

Trinity Eco Prayer Park plantings are arranged to reflect four separate biomes found in western South Dakota. Species common to Shortgrass Prairie, Midgrass Prairie, Black Hills and Wetlands can be found in the park surrounding the traditional central lawn.

These plants, grasses, shrubs and trees occur naturally in the region and are well-adapted to the areas extremes in temperature, variations in moisture and ability to survive, and in some cases even thrive, in what would normally be considered poor soil conditions. This is in keeping with sustainable landscape design principles, which creates a low-maintenance natural setting that requires little or no watering or use of chemical fertilizers.

In addition to creating a natural space in downtown Rapid City, the park provides an environmentally-friendly landscaping model that may inspire visitors to include some of these species in their yards. Sustainable Landscape Construction: A Guide to Green Building Outdoors by J. William Thompson and Kim Sorvig is good, detailed resource to guide those interested in adopting this approach to caring for their corner of the planet.
