|Adjacent land uses||- Have land uses changed while the design was in progress? Are there any planned land-use changes on adjacent properties and is their drainage connected to the site?

- Will it create dirty runoff that may flow onto the construction site or into the LID feature?

|Natural heritage features and existing vegetation ||  

|Natural heritage features and existing vegetation || - Do the designs accurately capture existing natural heritage features? Which areas on the site should be protected during construction, and will these exclusion areas make the LID facility more difficult to construct? Where are the drip lines of the site's trees?
