Parking Lot Guidelines

Parking Lot Design Guidelines​

When parking lots are designed with winter maintenance in mind, they naturally require less salt application to maintain the same level of service without increasing liability. Using less salt in parking lots will help to mitigate anticipated chloride increases in local watercourses as urban development continues.

To assist with this goal, LSRCA and our partner agencies have developed ‘Parking Lot Design Guidelines to Promote Salt Reduction’. They includ​e design features, site plans, template municipal policies, and next steps intended for use by designers, regulatory agencies, owners, contractors, amongst others.  

The guidelines and associated documents and drawings are available below for download.
