Encroachment and Joint Use Agreement for the installation of an
outdoor living space within a variable width drainage easement
located at 816 Shorecrest Drive. This agreement will allow the
applicant to install a new outdoor covered patio, fireplace, and

The drainage easement was dedicated along the rear of the
property for an existing creek that runs west to east. This property
does have FEMA floodplain at the rear of the property, however,
the proposed improvements are located outside of the floodplain.

improvements will not impede drainage flow, will not encroach into

impacts to neighboring properties. The base flood elevation at this
location is at elevation 602', and the proposed improvements will be
at elevation 603.5' at the bottom of the wall, and elevation 605' at
the top of the patio. The proposed improvements will be located
1.5' above the base flood elevation and will not impact the existing
