documents are in compliance with the County Land Development Code and Chapter 177, Florida
Statutes. This project is within the Sonoma Oaks PUD, Ord. 10-48, as amended. All fees have been paid.

Attorney’s office prior to the recording of the final plat. This procedure is in conformance with Section
10.02.04 F.2 of the Land Development Code.
The Development Review Division recommends that the final plat of Sonoma Oaks be approved for
recording.

except when the applicant elects to delay obtaining a COA for non-residential developments that are
required to obtain approval of a site development plan prior to the issuance of a building permit.
LEGAL CONSIDERATIONS: The applicant is requesting approval of the final subdivision plat and
construction and maintenance agreement. The Board shall consider the County Manager or designee’s
recommendation and shall take evidence and testimony in regard to the final subdivision plat
requirements identified in LDC sections 10.02.04 B, 10.02.04 C, and other provisions of the LDC, as well
as Chapter 177, Florida Statutes. If the Board denies or places conditions on the final subdivision plat, it
shall state reasons for such denial or conditions.
In accordance with the LDC, the applicant is required to submit the final subdivision plat to the County
Manager or designee for recording within 18 months of the date of approval of the final subdivision plat
by the Board. However, following approval by the Board, but prior to recordation, the County Ma nager
or designee may approve minor insubstantial changes to the subdivision plat, and the Board may approve
any changes that are not minor and insubstantial.
This item has been approved as to form and legality, and requires a majority vote for Board appro val. --
