2. The applicant shall create a zoning lot and recombine the two properties as one parcel.
We have contacted your engineer to get estimates for the erosion control measures as part of the
development. We have also estimated your landscaping requirements for the development.
Once we have all these numbers, I will draft the site plan permit that must be executed by Twin
Cities Self Storage, LLC. Note that if there is a different property owner and/or mortgage holder
on the property, they will need to sign the consent(s) at the end of the permit. Once you have
executed the permit, it must be returned to me for City execution and recording at Carver County
within 120 days of the approval (by March 10, 2015) and prior to the issuance of a building
permit. The required security specified in the site plan permit (for erosion control and
landscaping) shall be submitted in conjunction with the site plan permit. Once this is recorded
and erosion control installed and inspected, a building permit may be issued.
A separate building permit application and review is required for the actual building
construction. We recommend that you begin the building permit review as soon as possible.
A copy of the executed permit will be returned for your files. Should you have any questions,
please contact me at (952) 227 -1131 or by email at bgenerous (a,ci.chanhassen.mn.us.
