The park was located at the northwest corner of Drainage System II. The Impervious Surface Coverage (Table 2,attached)indicated that"Park"was 10.02 acres within System II and would be 15%impervious surface. 1980 Permit(X000000561) A Permit Modification was issued Jan. 10, 1980 for the Amenity Pod Park(permit attached). The park was proposed with a building, roadway, parking area,and tennis courts with a 1.3 acre shallow detention area connected by culverts. The project description and exhibit in this permit shows that the park is located between System II and System III. One 19"x30" pipe connected the park detention area to the Drainage System II to the south. The Permit Summary indicates that the Park development area is 4.6 acres; however,the SFWMD Board Meeting project description and the engineer's report indicate that the total Park property is 10 acres. "Of the 10 acres designated as park,approximately 33%will be developed,the rest will be left as natural vegetation". The permit information also states"the runoff will then become part of the water management system of Pelican Bay in which it will be discharged through control weirs to the wetlands via spreader swale". Stormwater calculations were found that indicate the 4.64 acre park in post development would be 58% impervious. Although not explicitly stated in the permit,this equates to 2.69 acres impervious coverage. 1998 Permit(980717-16) A Permit Letter Modification was issued Aug. 27, 1998 (attached),for a 4,800 sq.ft. building addition and asphalt paving of an existing brick paver area behind the building. The plans by Kepple Engineering,2 sheets were also permitted by Collier County at that time. The SFWMD and County plans (2 sheets attached) included new trench drains and storm inlets around the building,discharging through two 12" PVC pipes directly to the west vegetation area. These pipes were shown on the plans, but were not noted in the project description. There was no indication of proposed water quality or stormwater attenuation volumes for the site. 1999 Permit(981221-14) A Permit Letter Modification was issued Jan. 28, 1999(attached),for relocation of a dumpster pad. No plans were included, however the same plans by WJ Johnson&Assoc.were also permitted by Collier County at that time. Collier County Site Development Plan permits(SDP) 1998 SDP(98-99) The oldest SDP we found was SDP 98-99, approved Aug 20, 1998,which coincides with the 1998 SFWMD Letter Modification by Kepple Eng.for the 4,800 sq.ft. building addition and paving area. These plans show the main building,all ten tennis courts,and all the parking lots as"existing". These "existing"site improvements were constructed at some time prior to 1998. Collier County historical aerials(attached) show that in 1985 the main building,four tennis courts,and portions of the parking lot existed. The 1995 aerial shows the additional six tennis courts and parking were added at some time between 1985 and 1995. We could not find Collier County or SFWMD records indicating that all of the original "existing"site improvements were reviewed and approved. Because the original building and portions of the tennis courts and parking were constructed prior to 1985, it is likely that these improvements would have been shown on a Building Permit application,which pre-dated the Site Development permit process. 2003 SDP(AR-3604) An SDP Insubstantial Change (letter attached)from 2003 (SDPI-2003-AR-3604) permitted some new parking spaces along the north and west parking lots, and the relocation of the 8'wide path toward the west. The County SDP review comment response letter from Feb.27, 2003, indicates that"a letter mod from SFWMD will be forthcoming and no water quality treatment is required". The site plan (attached) shows the proposed changes but does not indicate any proposed stormwater improvements. No SFWMD permit modification was found. 2003 SDP(AR-4213) This SDP Insubstantial Change(SDPI-2003-AR-4213)was permitted June 23, 2003,to permit the Phase 2 (west) improvements as previously shown on the AR-3604 SDP plan. There were some additional tree removals and minor revisions to the bike path. Other Relevant Documents 1981 PBID Review Photo copy portions of a plan from January 1981 (5 sheets,attached)show the original parking lot and tennis court site plan design. This plan was reviewed by PBID and stamped/checked"approved as noted"and "water management". Although reviewed by PBID's District Engineers,we found no evidence that this plan was submitted and reviewed by Collier County and SFWMD. It is possible that this plan could have accompanied a County Building Permit for the Commons,which was customary at that time. These plans show the 30 linear feet of 19"x30"discharge culvert to the south,which coincides with the design in the 1980 SFWMD Permit Modification. 2014 Design and Permitting Plans have been submitted by Hole Montes&Associates to Collier County(PL2013-1389)and to SFWMD (140331-16). The plan includes modifying existing parking lot circulation and relocation of the tram pathway and new tram building,and other minor adjustments. The general drainage design and flow patterns of the existing site will remain,in that the parking lot sheet flows into storm inlets and pipes with two primary discharge points:the northwest corner discharge point into the vegetation preserve, and the south discharge point into the System II shallow detention area,and one secondary discharge point:the two 12" PVC pipes from the building trench drains to the vegetation preserve. The south discharge point is an existing 19"x30"diameter pipe. This is an open pipe that has been connected to System II since the early 1980's and will remain in place. System II drainage is controlled by the water management berm (tram pathway)and nine discharge weir structures. The northwest discharge currently consists of two 14"x23" pipes that discharge directly to the vegetation preserve (open pipes). Currently,this open pipe discharge is not controlled by a structure,which allows stormwater discharge to flow directly into the preserve. The new design will reconfigure the 14"x23" pipes to capture the stormwater runoff and collect it in a proposed detention area. According to the design calculations,this area provides the 1"water quality volume required by SFWMD (see attached email correspondence from Daniel Waters of SFWMD),and detains the stormwater prior to bleed-down discharge to the preserve via a 3"diameter circular orifice. The two 12"PVC pipes around the building will remain. The existing detention area along the east side of the tennis courts will remain,which continues to provide detention storage volume prior to discharge off-site. The previous County and SFWMD Permits did not identify a proposed impervious coverage by land use (parking lots,sidewalks, buildings)and did not quantify the proposed water quality storage or attenuation volumes. There was only reference in the original permits to the 15%impervious coverage, and later the 58% impervious coverage. So far to date,the current plan is the first we have found that identifies the existing and proposed impervious coverage by land use categories. An Impervious Coverage by Land Use Table is included immediately following the Conclusions below. As shown in this Table, impervious coverage will increase by approximately 4%from existing percent impervious. Conclusions The original SFWMD Permit in 1978 allocated 15%impervious coverage for the 10 acre Park site. The 1980 Permit provided for 58%impervious coverage of the 4.64 acre developed park area (2.69 acres impervious). In 1981 site plans were reviewed by PBID District Engineer that generally coincide with the 1980 SFWMD Permit. These plans show the tennis courts and parking lot and perimeter driveway. There were no plan or permit documents found after 1981, until 1998 when the Kepple plans made a minor change to the site, and showed all ten tennis courts and parking lots as existing. The subsequent 1999 and 2003 permit changes were minor changes to the parking spaces and path. Each of the plan and permit changes done after 1981 did not provide a land use table of site areas by uses,and did not quantify the provided water quality or attenuation volumes. Although not specifically stated in the permits,the 0.5 acre detention area along the east side of tennis courts and the network of swales and pipes between the parking lots appears to provide the typical minimum requirement of 1"water quality volume on site. The 2014 plan proposes some minor changes to the parking circulation,pathway and tram building. The proposed impervious coverage is an increase of 4%of the existing impervious area. Approximately 0.37 acres impervious area (sidewalks) is being added and 0.06 new detention area is added. The new detention area represents 14%of the new land area, which is within the typical parameters of percent water management land area provided. As stated in the SFWMD Permit Modification,this new 0.06 acre detention area provides the required 1"water quality volume for the new development area. The south discharge point(19"x30" pipe)will remain in operation as it has since the early 1980's. Approximately the southern half of the Commons park site drains toward this discharge pipe. The proposed improvements on the south portion of the site are limited to new sidewalks,which should be insubstantial to the existing runoff contributed to this pipe. The total flow capacity of this existing pipe does not change,so the pipe should flow at about the same rate(cubic feet per second)when flowing at capacity. The 12" PVC discharge pipes from the building will remain in operation as they have since 1998. Stormwater runoff from building roofs is considered "clean water"and is typically not required to provide water quality storage on the site. For this reason the existing direct discharge to the preserve should not be a problem. However,there are trench drains and inlets connected to one of these pipes that can allow some parking lot runoff to enter this discharge point. There have been reports from residents that dirty water and debris was seen running into the preserve. This situation should be remedied by adding storm filters within the inlets or diverting this water into a sediment trap. The northwest discharge pipes currently discharge directly into the preserve. These pipes will be reconfigured to capture the runoff in a new detention area. The new control structure will slow down (detain)the release of water into the preserve to provide additional water quality treatment. There are four questions posed by the PBSD with responses below, based on the information discovered. Would the project result in the impervious limit being exceeded in the basin in which the Commons is located? Yes, based on impervious areas identified in the original permits. The 10 acre park at 15% impervious was included in the System II area in the original 1978 permit. On the plan (Sheet 4 of 43) the park appears intended to be a part of System II, but Parcel J is located between the containment berms between System II and System III. The park was then presented as 58%impervious(equivalent to 2.69 acres coverage) in the 1980 permit. The permit exhibit and language indicated that the park may not have been within a particular basin but discharges to System II. Subsequent permits including the current Permit Modification have included all of the park impervious areas as"existing",although these areas may have exceed previous identified coverage. Because of the sparse permit documentation it is not clear whether the park is definitely in its own unidentified basin,or if it is subject to a maximum limit within System II. Is the Commons water management area on a drainage easement that is part of the PBSD master drainage permit? No,there do not appear to be drainage easements within the Commons site over the water management areas. There is a drainage easement along the south of the property (OR 943, Pg 1865)that likely was relocated or vacated to accommodate the acquisition of 0.15 acres and construction of the Commons parking lot,where the System II berm used to be. A title search is being requested to clarify easements. Would the Commons project represent a substantial change to the existing Commons site development plan? No,the new impervious area is approximately a 4% increase to the existing percent impervious area. Additional dry detention storage and water quality treatment is being provided for the new area. Would the Commons project affect a platted or recorded property interest? No,not substantially. The new improvements are proposed within the Commons property. There are two portions of the path that will be constructed on adjacent properties:one sidewalk connection to the south and one tram connection to the north. The proposed impervious coverage and drainage changes are not substantial compared to today's existing conditions and the 4%increase is being compensated in the new dry detention area.

Box "V" West Palm Beach, Fla. 33402 ! � RE: Pelican Bay Amenity Pod Park ''25 File No. 79.13 Dear Dick: Enclosed please find a report outlining the proposed water manage- ment plan for the Pelican Bay Amenity Pod Park. As you will note from the enclosed report, the water management plan calls for storage of storm water runoff in natural detention areas located within the park site with a final discharge into System No. II. Basically all the other criteria used in designing the Pelican Bay System was used in designing the park drainage system. We request that you review the enclosed material in order that a modification to the Pelican Bay Water Management Plan can be made to permit the construction of the proposed improvements to the Amenity Pod Park area.

PROJECT DESCRIPTION: Pelican Bay Amenity Pod Park is a ten acre parcel planned as a central community recreation area which provides space for court games, picnic tables, and an elevated boardwalk IV. STAFF COMMENTS: The site drainage plan and supporting calculations have been reviewed by the County Engineer and the WMAB Consultant, and they find them to be in compliance with the County Water Management Criteria. The discharge from Pelican Bay Park will become a part of Pelican Bay Water Management System which provides detention areas sufficient to retain the difference between predevelopment and postdevelopment for a 25 year, 24 hour storm.

Purpose This report is presented to the South Florida Water Management District in order to obtain a permit for construction approval of the proposed Amenity Pod Park in Pelican Bay. B. Location The Pelican i3ay Amenity Pod °ark is a 10-acre parcel of land bounded on the east by Pelican Bay Blvd. , on the south by drainage system no. II berm, on the north by drainage system no. III berm and on the west by the Pelican Bay P.U.D. zoning line (see Figure 1) . C. Land Use The park is planned as a central community recreation area providing space for court games;; picnic tables, and an elevated boardwalk. PELICAN BAY PA' K Page 2 of 4 Oi th • 10 acres designated as the park, are r..tely 33% will 13 developed, to e rest will be left as ural veg- etation. D. Existing Lrainage The Pelican Bay Park area is presently undeveloped. The natural vegetation consists of pine palmetto lands in the easterly portion and transitions to lowland vegetation (hard- wood hammocks, black rush marsh, etc.) . The existing ground elevation in the park varies between 4.8' m.s.l. to 3.0' m.s.l. Drainage occurs naturally with runoff flowing from east to west and eventually enters the Clam Bay System. E. Concepts of the Proposed Water Management Plan The proposed water management plan is similar to that de- veloped for Pelican Bay. It consists of a system of shallow interconnected detention areas formed by the difference in el ovation between natural ground and the proposed pavement. Runoff will be stored in the detention areas which are inter- connected by culverts and will eventually be discharged into the detention area upstream of the system II berm in Pelican Bay. The runoff will then become part of the water management system of Pelican Bay in which it will be discharged through control weirs to the wetlands via a spreader swale. 1 1 DRa IN AGE. -(,.4,ta CA �r:.., ■ SYSTEM ;� _ \e Irk '� . `0 %t a %‘ 1 P ', i .;', s.'

Dan Waters, PE South Florida Water Management District 2301 McGregor Boulevard Fort Myers,FL 33901 Ph:(239)338-2929(ext.7763) Fax: (239)338-2936 Email:dwaters@sfwmd.gov From: George Hermanson (mailto:GeorgeHermansonfthmeng.com] Sent:Thursday, May 01, 2014 1:22 PM To:Waters, Daniel Cc: McKennaJack Subject: Pelican Bay Commons Appl. No. 140331-16 Dan, As follow up to our meeting on Tuesday,this is my summary for the response to comment Nos.2 and 3 in your staff's letter dated April 24`h. These comments had to do with discharge rates,detention volumes and water quality resulting from the modifications to this storm water management system. As your staff may recall from the preapplication meeting of last August 5'h,the plan was to slightly modify and relocate the detention areas and maintain the volume of detention of one inch over the drainage area,which was the original basis for permitting the site. Our first submittal included plans and calculations verifying that one Inch of detention would be maintained. We also pointed out that we were adding a control structure to regulate discharge and control the detention storage in the system,which currently did not exist. In Tuesday's meeting you recommended,as a response to these comments,that we provide additional retention volume for the added improvements on the west side of the site. This volume would occur below the control elevation of 4.0'and the storage quantity would be one inch over the added area,plus 50%per current SFWMD water quality policy,then credited by 50%per the Basis of Review. Attached is a site plan highlighting the added area of Improvements which Is approximately 24,200 square feet. The retention volume is: 24,200 x 1/12 x 150%x 50% 1,513 CF The new westerly detention area will provide this retention volume. The bottom of this area is approximately 3,590 SF with an average elevation of approximately 3.5 ft. (0.5 ft.below control),and this bottom area will be left at existing grade. The retention volume provided is: 3,590 x 0.5 1,795 CF Therefore,this detention area will also accomplish your recommended retention. 1 We request that you confirm that the above adequately addresses your staff's comments and represents an acceptable design,or please let me know If you have any additional questions.
