Engineering/Drainage

  1. Plan review is required for drainage reports and other engineering which is distinct from the construction of structures. A Phase III Drainage Report is required for any new home or major addition, as well as for any project which adds 2,500 square feet or more of impervious surface to a lot. Note that in addition to a Phase III Drainage Report, a Stormwater Management Plan and associated Stormwater Construction Permit is required for projects which disturb one (1) or more acres of land. Please call the Community Development Department at 303-783-2721 if you are unsure if your engineering documents should be reviewed in this manner or have any questions on engineer review.
