Applicant’s Response

Refer to the updated Site Based Stormwater Management Plan (SBSMP) prepared by MCE, indicating that
the proposed development will discharge stormwater runoff inside the subject site’s property boundary at
pre-development drainage conditions. As the subject site will maintain existing drainage conditions,
permission to discharge downstream is not required in this instance.

Please refer to Attachment A - Engineering document prepared by Morgan Consulting.
