Once complete, the next step is to assess site conditions in order to confirm your assessment, determine the technical feasibility of implementing LID practices within the municipal ROW, (i.e., the existing drainage conditions and general ROW characteristics), and identify and confirm any existing constraints. Pay attention also to the function of adjoining land uses and the activity that occurs in and around when noting site conditions.

The next step is to assess site conditions in order to confirm your assessment, to determine the technical feasibility of implementing LID practices within the municipal right-of-way (ROW), to scope existing drainage features and general ROW characteristics, and to identify and confirm any existing constraints. Pay attention to the function of adjoining land uses and activities occurring in and around the site.

Site specific constraints, considerations, and conditions that can be identified during a field visit include:

Complete removal and replacement of the major ROW elements including the road base, asphalt surface, concrete curb and sidewalks. Complete replacement can include reconstruction or replacement of the sub-surface (hydro, gas, water main, sanitary and stormwater infrastructure).

Another type of road reconstruction converts rural cross-section roadway into an urban cross section. This typically includes the installation of storm sewers, complete base and asphalt replacement, concrete curb placement, placement of sub-drains under curbs and catch basin placement.

The effective width or number of travel lanes contained in a crosssection is reduced in order to achieve system improvements. Roadway reductions can be used for traffic calming purposes, transit projects, alternative transportation strategies (e.g. introducing bicycle lanes), and pedestrian crossings. Through the process of roadway reduction, areas of the ROW that were used for vehicular travel are converted to sidewalks, landscaped boulevards and bicycle lanes.
