Understanding site conditions is critical when [[Screening LID Options]]. Gaining comprehensive knowledge of the proposed site requires a desktop review of relevant background information followed by field reconnaissance to verify the review and identify relevant site conditions not included in background information.

Reviewing background information will help provide preliminary understanding of side conditions, scope technical investigations for the site and determine project targets. It’s best to collect and review this information prior to field reconnaissance so that it is targeted and efficient use of time.

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.
