David Flick, Principal and Founder, announces that the firm has successfully completed a Degraded Pasture Assessment for a future Residential Development in Overland Park, Kansas. The City of Overland Park, Kansas promulgates rules that require a developer to ensure that the quality of post-development storm water runoff does not exceed the quality of pre-development storm water runoff. Using a methodology that incorporates predevelopment features including pasture, woodlands, and existing impervious surfaces, a metric is computed to determine the present water quality value.
A Degraded Pasture Assessment evaluates 9 different measures of grassland conditions:
- Plant Population
- Plant Diversity
- Plant Vigor
- Legumes in Stand
- Severity of Use
- Uniformity of Use
- Soil Resources
- Undesirable Plant Canopy
- Plant Residue
These 9 different measures were determined separately for each pasture within the assessment area then added together to produce numerical score. This numerical score was then entered into a formula to determine that the actual pasture score of the assessment area was 3.34. According to the City of Overland Parks Pre-Development Pasture Scale a 3.34 is classified as a Degraded Pasture. This classification is then used to determine the extent and amount of BMPs (Best Management Practices) needed to ensure that post-development storm water runoff does not exceed the quality of pre-development storm water runoff
