Agenda 06/10/2014 Item #16A16 6/10/2014 16.A.16.
EXECUTIVE SUMMARY
Recommendation to determine that the proposed Walgreens Rezone project satisfies the criteria for
exemption to allow for a stormwater discharge rate above the.15 cubic feet per second (CFS) limit
expressed in Policy 6.3 of the Stormwater Management Sub-Element of the Growth Management
Plan(GMP)(Companion to RZ-PL20130001302).
OBJECTIVE: To have the Board of County Commissioners (BCC) determine that the proposed
Walgreens Rezone project satisfies the criteria for exemption to allow for a stormwater discharge
rate above the .15 cubic feet per second (CFS) limit expressed in Policy 6.3 of the Stormwater
Management Sub-Element of the Growth Management Plan.
CONSIDERATIONS: Policy 6.3 of the Stormwater Management Sub-Element limits the
stormwater discharge rate for projects, with the limits of discharge allocated per basin. When
not basin specified, the limit expressed is .15 cfs/acre. Contained in the same policy is a
provision which states, "The County may exempt projects from these allowable off-site discharge
rates if any of the following applies. 1. The project is part of an existing South Florida Water
Management District (SFWMD)permit, which allows discharge rates different than those listed
above. 2. It can be documented that the project currently discharges off-site at a rate higher
than those listed above." The full policy has been attached within Exhibit"A".
The Walgreens Rezone is a proposed redevelopment project located on a 1.79-acre parcel,
currently developed as the Teddy Bear Museum within the YMCA facility, at the northeast
corner of Airport Road and Pine Ridge Road. Currently, the proposed project is part of an
existing SFWMD permit that exceeds the policy limits and could qualify for the exemption
as contained in Policy 6.3. On April 28,2014,the County received a correspondence from Bruce
Anderson (Exhibit "B") representing the project developer, requesting that the project be
determined to qualify for the exemption allowed for by Policy. Within the correspondence, Mr.
Anderson states, "Policy 6.3 allows the County to expressly exempt this project under
Paragraph #2 by the fact that YMCA project, which the subject site is a part of is in possession
of an existing permit, which allows a discharge rate of 4.07 CFS/ACRE." The current allowed
discharge rate of 4.07 cfs/acre, as documented in the attached Stormwater Report (Exhibit "C")
allows for the project to qualify for the exemption based upon the existing permitted District
discharge rate exceeds the .15 cfs/acre limit of Policy 6.3. Additionally, the applicant has
provided a"Runoff Narrative"(Exhibit"D"),which condenses the Stormwater Report by its key
points.
FISCAL IMPACT: There is no fiscal impact associated with this Executive Summary.
LEGAL CONSIDERATIONS: This item is approved for form and legality. A majority vote is
needed for Board approval. -HFAC
GROWTH MANAGEMENT IMPACT:,Policy 6.3 of the Stormwater Management Sub-Element
states that the County may exempt projects from the .15 cfs/acre stormwater discharge rate limit.
The BCC's decision on exempting qualifying projects from the discharge rate limit, is in
compliance with the GMP.

Hi Mike,
Attached are the applicable docs to support Exemption #2 under Drainage Sub element Policy
6.3. In addition to the technical support docs which are attached, I asked the engineers to
explain it in layman's terms and that explanation is in the attached narrative. The rezone is
set for June 10 BCC mtg. If the rezone qualifies for Summary Agenda, will you place the
drainage discharge exemption on Summary as well, since there is no disagreement?
Pls let me know if you have any questions on the attachments and I'll try to get answers -For
you.
Thank you for your assistance in moving this along.
Bruce

The attached email is what I sent Jack and Carmen initially. The most recent stormwater
report is attached as well as a narrative describing the increased runoff.
Jack never responded via email approving this, he told me verbally that he was ok with it.
Carmen with SFWMD is reviewing the ERP application as I write this from what she told me
today.
Please let me know if you need anything else.
Thanks,

Exhibit"D"
Upon review of the previous stormwater permit documents and the survey of the subject
property it was discovered that a large portion of the previously permitted pond volume did not
exist in the developed condition. This reduction in volume created a situation whereby the
previously permitted discharge rate and pond stages were no longer valid in the real world
conditions. The discovery was reviewed by the South Florida Water Management District and
Collier County Staff. Staff assessed the existing conditions and supporting documentation. It
was decided that an increase to the allowable discharge rate matching the undeveloped
condition of the site would be the best solution to this challenging issue
The rate increase requested under GMP Policy 6.3, #3 is related to the condition of the site
before any development took place. The site originally was a mixture of pine uplands and
wetlands that drained generally from east to west towards Airport Pulling Road canal. No
containment features existed on the site in the original condition, i.e. ponds, lakes, or berms to
restrict the flow.
The original condition was modeled using a program titled ICPR, which uses input from the
designer to generate a peak flow rate for particular storm events. The input includes basin area,
time of concentration (meaning how long it takes runoff to move from the furthest point in the
basin to the outfall, in this case the Airport Pulling canal), soil types, and land cover information
to setup a drainage area. The storm event required for by the SFWMD and Collier County is the
25 year/ 3 day storm. The 25 year frequency means there is a 4% chance that the event will
happen in a given year. The 3 day duration dictates that the model is run showing rain over the
basin for 72 straight hours. The amount of rain over this duration is 8.5".Considering this major
storm event a peak runoff or discharge of 4.07 cubic feet per second (cfs) was generated in the
original undeveloped condition. 4 cfs is approximately the rate of discharge of a 6" PVC pipe
flowing full down a hill.
The proposed system will recoup volume using advanced stormwater treatment techniques and
make slight adjustments to the existing control structures to limit the site discharge to less than
the undeveloped condition and much less than the existing system's discharge, as well as
provide more than the required water quality treatment. In addition the proposed discharge
rate combined with improvements to the pond will greatly reduce the potential for off-site
flooding of the adjacent developments.
