Vehicle parking is a significant source of impervious cover in the Chagrin River watershed. It is well within the purview of local governments to examine parking requirements and modify as necessary to meet actual parking needs. To assist members in updating parking requirements as a tool to minimize impervious cover, CRWP:

  • Examined current parking requirements and actual parking needs in several representative Chagrin River watershed communities to determine where communities are requiring excess parking lot construction.
  • Examined national trends in parking requirements for innovative solutions to minimize parking requirements while meeting parking needs. Such innovative solutions include shared parking between uses that occur at different time such as churches and offices. The results are summarized in Review of National Trends in Parking Requirements (pdf 12MB, published in 2005).
  • Developed a model parking code for member consideration.
  • Developed a fact sheet, Parking Lots, Impervious Cover & Storm Water (pdf 156 KB published in 2006), which introduces options to reduce impervious cover in off street parking areas.

It is hoped that this model regulation will be helpful to local governments in their efforts to provide effective stormwater management throughout the Chagrin River watershed.
