Agenda 02/28/2023 Item #16A11 (Re-assumption of maintenance responsibilities of the perimeter drainage easement at the Imperial Golf Estates Development)16.A.11
02/28/2023
EXECUTIVE SUMMARY
Recommendation to approve re -assumption of maintenance responsibilities of the area located
within the perimeter drainage easement around the three sides of the northeast section of the
Imperial Golf Estates development.
OBJECTIVE: To maintain appropriate sections of existing secondary stormwater and surface water
management infrastructure providing regional flood protection level of service benefit to Collier County
residents.
CONSIDERATIONS: The original design of the Imperial Golf Estates development included land
around the perimeter of the northeast sections of the residential area designated for water management. In
the 1970's, this area experienced overland sheet flow of surface water from adjacent undeveloped lands to
the north moving in the historic northeast to southwest flow direction. Through the original design,
permitting, platting and construction of the Imperial Golf Estates Development, a drainage easement was
attached to the subject land designating use of the land for the intended purpose of water management.
This area was maintained by the original Collier County Stormwater Management Department formed in
the 1980's for a number of years, presumably due to the challenges associated with water management in
an area that experiences regional sheet flow. At some point the Imperial Golf Estates homeowner's
association began maintaining the area. The perimeter drainage easement area is still currently being
maintained by the HOA, despite the fact that is serves as a regional drainage facility.
The area surrounding this portion of Imperial Golf Estates has since become developed. Surface water
and stormwater flow characteristics of the area have changed. Approximately three years ago, when
design and permitting began for the construction of the new adjacent high school and the new Veterans
Memorial Parkway, residents of Imperial Golf Estates became concerned about potential new water
management challenges resulting from these projects. Designs for both projects included new direct
drainage connections to the Imperial Golf Estates perimeter water management area.
To address concerns and take appropriate action the County agreed to offer re -assumption of the
maintenance responsibility of the approximately 5 acre perimeter drainage easement area, as it is a
drainage easement intended for and currently accepting regional stormwater flows. An engineering
drainage basin study to identify any existing facility deficiencies to target for future improvement was
completed in September 2022.
FISCAL IMPACT: The annual cost to assume maintenance responsibility, including mowing,
vegetation trimming, and aquatic herbicide application is estimated to be $50,400. The source of funding
for the maintenance is Stormwater Maintenance Fund (103), the drainage basin study was funded by
Stormwater Capital Fund (325).
LEGAL CONSIDERATIONS: This item has been reviewed by the County Attorney, raises no legal
issues and requires majority vote for approval. -JAK
GROWTH IMPACT: There is no Growth Management Impact resulting from this action.
RECOMMENDATION: That the Board of County Commissioners approves re -assumption of
maintenance responsibilities of the area located within the perimeter drainage easement around the three
sides of the northeast section of the Imperial Golf Estates development.
