The characteristics, LID opportunities and constraints, and examples are presented for each of these ROW types on the following pages. Typical LID options for each of these street types are offered. However, this guidance is not intended to be prohibitive of other LID options, but rather to help reduce the number of LID options in the preliminary phases of screening and alert the designer to LID opportunities unique to that road type. Other considerations such as adjacent landuses, traffic demands, utility locations, budget constrains and geological conditions will determine the most appropriate LID solution

A road primarily for through traffic.

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.
