We have been asked to prepare a site design plan for a local developer, including grading S& E, and stormwater. The site is a small commercial development. The client has also asked us to prepare the landscape plan. The landscape plan does not have to be sealed. Would we be stepping into a possible trouble spot if we were to preapre the landscape plan even though we do not seal it. The requirement and most of the info is in the local code. Thanks for you input.
