NAME OF PETITIONER/PROJECT: Petition No. : ST-92-16 Petition Name: Boat Dock Applicant/Developer: Troy Zinser Environmental Consultant: N/A II. LOCATION: North 100 feet of Government Lot 3 , Naples South in Section 14, Township 51 South, Range 25 East, Collier County, Florida. III. PROJECT DESCRIPTION: The subject property is located on Key Island. The lot is approximately 100 feet wide by 1000 feet long. The lot is zoned A-ST. The petitioner proposes to construct a boat dock that is approximately sixty (60) feet in entire length and four (4) feet width with a one hundred sixty (160) square foot access platform. Plan of Record: Environmental Impact Statement Information dated August 14, 1992 . IV. STAFF COMMENTS: A site visit was conducted on August 6, 1992 by Kimberly J. Polen of Collier County Project Review Services Environmental Staff and Bob Reppening of Florida Department of Natural Resources Aquatic State Preserves. The site has an existing single family home within the western half of the parcel, access is by boat from the west. Sea grass beds consisting of shoal grass (Halodule wrightii) are present within the intercoastal waterway. Vegetation on site is characteristic of a xeric tropical hammock as one moves from the west to east. Vegetation is as follows: sea oats (Uniola paniculata) , seagrape (Coccoloba uvifera) , prickley pear cactus (Optunia spp. ) , dune-elder (Iva imbricata) , marsh-elder (Iva spp. ) , sea myrtle (Baccharis halimifolia) , Australian pine (Casuarina spp. ) , Brazilian pepper (Schinus terebinthifolius) , EAB Meeting 9/2/1992 ST-92-16 Page 2 cabbage palm (Sabal palmetto) , gumbo-limbo (Bursera simaruba) , Jamacian dogwood (Piscidia piscipula) , strangler fig (Ficus aurea) , myrsine (Myrsine floridana) , wild coffee (Psychotria spp. ) , coco plum (Chysobalanus icaco) , Virginia creeper, (Parthenocissus quinquefolia) , coin vine (Dalberghia ecastophyllum) , Christmas-berry (Lycium chrolinianum) , green buttonwood (Conocarpus erectus) , white mangorve (Laguncularia racemosa) and red mangrove (Rhizophora mangle) . The petitioner proposes to construct a boat dock that extends east and west along the central shoreline of the property. Vegetation within the proposed location consists of one (1) large Brazilian pepper at the water line, three (3) green buttonwood that are less than four (4) inches in diameter at breast height, two (2) Christmas-berry and one (1) myrsine. Staff identified an area devoid of any woody vegetation located approximately eighteen (18) feet north of the south property line. This altered area was recognized as the best alternative. Therefore, Staff requested that the petitioner provide additional environmental impact statement information to substantiate his proposed alternative verses Staff's recommendation (See Section 3 . 8 . 6 of the Environmental Impact Statement Information) . V. CONCLUSION: The petitioner is well aware of the environmental sensitivity of the Key Island barrier system, and has proposed a structure which reflects this concern. He is also in a position where he cannot build a boat dock within less than twenty-five (25) feet from his south property line unless he receives permission from the adjacent property owner to the south which has a thicker mangrove shoreline especially to the south. VI. RECOMMENDATIONS: Based on the above considerations Staff recommends approval of Special Treatment Permit ST-92-16 "Troy Zinser - Boat Dock" with the following stipulations: 1. Permits or letters of exemption from the U. S. Army Corps of Engineers, Florida Department of Environmental Regulation, and Florida Department of natural Resources shall be presented prior to issuance of a building permit.

NAME OF PETITIONER/PROJECT: Petition No. : PSP-92-8 Petition Name: Manors at Regal Lake Applicant/Developer: Regal Manor Limited, A Florida General Partnership Engineering Consultant: Agnoli, Barber & Brundage, Inc. Environmental Consultant: Turrell and Associates, Inc. II. LOCATION: Section 15, Township 48 South, Range 25 East; bounded on the north by Imperial Golf Course Boulevard, on the east by Park Place West subdivision, on the south by undeveloped land zoned A-2 and on the west by the development called Renaissance (previously known as Veri-Care of Naples) . This tract is part of the Imperial West PUD. III. PROJECT DESCRIPTION: The petitioner proposes to develop 14 . 33 acres of land into nine buildings with a total of 68 units. There is an existing 4 . 75 acre lake which will be used for water management purposes. The land will consist of 4 . 75 acre lake, 2 . 55 acres of building area, 2 . 16 acres of roads and parking, 3 . 97 acres of green area, a 0. 69 acre preserve (not to be included in the water management calculations) and 0. 25 acres of a recreation center. Plan of Record: Water Management: "Manors at Regal Lakes, Master Utilities and Drainage Plan, Collier County, Florida" prepared by Agonli, Barber & Brundage, Inc. ; dated June 17 , 1992 , no revisions. Environmental: "Manors at Regal Lake Environmental Impact Statement" prepared by Turrell and Associates, Inc. ; dated June 1992 . "Supplement to Manors at Regal Lake EIS" prepared by Turrell and Associates, Inc. ; dated 8/17/92 . EAB Meeting 9/2/1992 PSP-92-8 Page 2 IV. STAFF COMMENTS: Water Management: The proposed project lies within Imperial West Stormwater Master Plan which has a South Florida Water Management District (SFWMD) permit for the entire system. The existing 4 . 75 acre lake will be modified to meet the minimum requirements for an excavation in accordance with Section 3 . 5 of the Land Development Code and it will provide capacity to handle the runoff generated by the proposed project plus any off-site drainage coming onto site. The project water management system will take off site discharges from the Veri-Care site to the west and a portion of Imperial Golf Course Boulevard and route them through the system. There is an existing control structure located on the south side of the lake and discharging into Horse Creek which heads south into the Cocohatchee River. The discharge is being controlled at 7 . 69 cfs. The petitioner will obtain a modification surface water permit from SFWMD. The water management system has been designed for water quality and water quantity in accordance with SFWMD rules and regulations. Environmental: The project lies within the watershed of the Cocohatchee River. Prior to the creation of the existing lake, a tributary identified as FLUCCS code 626 bisected the property. After the creation of the lake, over the past decade, the drainage has been flowing around the western end of the lake which has created a stagnant low area. Ground elevations within the project site range from 3 . 0 to 7 . 0 NGVD. The historical seasonal high water elevation appears to have been much higher, maybe as much as a foot, than the present control elevation of 5. 3 NGVD. According to Exhibit #5 the Soil Survey of Collier County Area, Florida - Sheet Number 20 revised 1/90 , the soil types of the site include mostly Immokalee fine sand with a small area of Satellite fine sand in the southeast corner. Soils in the designated wetland areas are all hydric. There are approximately 5 . 01 acres of jurisdictional wetlands on site (35% of the site) , of which 0 . 61 acres consists of forested wetland, 1 . 34 acres consists of freshwater marsh and 3 . 06 acres consists of borrow areas. EAB Meeting 9/2/1992 PSP-92-8 Page 3 Fifty percent (50%) of the site consists of the following upland habitats: palmetto prairie (0 . 62 acres) ; pine flatwoods (5. 66 acres) ; and pine-mesic oak (0. 85 acres) . The remaining fifteen percent (15%) consists of spoil area around the main-made lake. In order to compensate for the twenty percent (20%) of the Collier County jurisdictional wetlands proposed to be impacted, the applicant is proposing to create, restore, and enhance the entire west end of the lake into a gradually sloped, diverse wetland system that will connect into the stream. Also the applicant is proposing to preserve approximately one (1) acre of upland and to creat additional littoral shelves within the lake perimeter. Due to the fact that the property is located close to the secondary zone of Bald Eagle Nest 2001, Staff recommends that slash pines and snags be retained within the development landscaping to serve as a visual buffer for the eagles and as potential future roosting sites. V. RECOMMENDATIONS: Staff recommends approval of Preliminary Subdivision Plat Petition PSP-92-8 , "Manors at Regal Lake" with the following stipulations: Water Management: 1. The lake as shown shall meet all the construction requirements for a development excavation in accordance with Division 3 . 5.7 of the Land Development Code. Environmental: 1. Prior to final construction plan/plat approvals the applicant shall submit all Federal, State and Local determinations and permits, waivers/exemption determinations that may relate to or effect the design and layout of said final construction plans/plats. 2 . Jurisdictional wetlands and/or mitigation areas shall be designated as conservation/preservation tracts or easements on the final construction plans and shall be recorded on the plat with protective covenants as per or similar to Chapter 704 . 06 of the Florida Statutes. EAB Meeting 9/2/1992 PSP-92-8 Page 4 3 . All proposed mitigation for wetland impacts to Collier County jurisdictional wetlands shall comply with Appendix 7 of the South Florida water Management District rules and be subject to review and approval by Project Review Services Environmental Staff . 4 . An exotic removal, monitoring and maintenance (exotic free) plan shall be submitted to Project Review Services Environmental Staff for review and approval prior to final construction plan approval .

NAME OF PETITIONER/PROJECT: Petition No. : PSP-92-10 Petition Name: Arbor Estates Applicant/Developer: Vineyards Development Corporation Engineering Consultant: Coastal Engineering Consultants Environmental Consultant: N/A II. LOCATION: Section 8 , Township 49 South, Range 26 East; bounded on the north and south by undeveloped land, on the west by existing Vineyards Golf Course, and on the east by Arbor Boulevard right-of-way. The project lies in a portion of Tract BB within the Vineyards PUD. III. PROJECT DESCRIPTION: The developer proposes to subdivide a 31. 81 acre parcel of land into 42 single family residential lots with an internal road and two (2) lakes. Arbor Boulevard, which will provide access to the development, will be built in conjunction with the project. The area breakdown will consist of 5 . 31 acres of right-of-way, two (2) 9 . 29 acre lakes, 1 . 06 acres of buffers and easements and 15 . 15 acres of lot area. Plan of Record: Water Management: "Preliminary Subdivision Master Plan" File No. 90126-3 prepared by Coastal Engineering Consultants, Inc. Dated 8/20/1992 , two revisions. Environmental: "The Vineyards - Arbor Estates Preliminary Subdivision Plat" prepared by Coastal Engineering Consultants, Inc. , dated June 1992 . IV. STAFF COMMENTS: Water Management: The proposed project lies within the Vineyards PUD which has a Master Water Management System. Within the proposed project site, the runoff generated by the development will be collected via EAB Meeting 9/2/1992 PSP-92-10 Page 2 swales, valley gutters, catch basins and pipes and it will be conveyed to the two proposed lakes. The lakes will store the water quality and water quantity requirements as per South Florida Water Management District (SFWMD) rules and regulations. These lakes will be connected through pipes to the existing lakes which form the stormwater system for the Vineyards. The petitioner will obtain a SFWMD surface water modification permit prior to any construction plans approval. This project is required to be reviewed and approved by the Environmental Advisory Board (EAB) since the proposed lakes were never part of the Vineyards PUD Master Plan. Also, the petitioner is required to obtain an excavation permit for the proposed lakes, in accordance with Division 3 . 5 of the Land Development Code. V. RECOMMENDATIONS: Staff recommends approval of Preliminary Subdivision Plat Petition PSP-92-10 , "Arbor Estates" with the following stipulations: Water Management: 1. The lakes as shown do not appear to meet the minimum setbacks from the right-of-way. Exceptions to these setbacks may be developed and shall be subject to final approval by the Development Services Director. Said exceptions shall be based on recognized standards for traffic engineering and road design (AASHTO) and shall incorporate such factors as road alignment, travel speed, bank slope, road cross-section, and need for barriers. This shall be done at the time of excavation permitting. 2 . Landscape buffer and lake areas shall be kept separate unless approved by Project Review Services. 3 . A SFWMD permit for the development of that portion of Arbor Boulevard which will serve the proposed project shall be obtained prior to final construction plans approval. Environmental: 1. All previous environmental standards of the Vineyards PUD Ordinance No. 85-15 shall continue to apply.

NAME OF PETITIONER/PROJECT: Petition No. : PUD-87-18 (1) Petition Name: "Cypress Glen PUD" Applicant/Developer: Littleton E. Walker III Engineering Consultant: Timothy L. Hancock, Wilson, Miller, Barton & Peek, Inc. Environmental Consultant: Craig Schmittler, Wilson, Miller, Barton & Peek, Inc. II. LOCATION: Section 12 , Township 49 South, Range 25 East; bounded by agricultural land to the north, Community School and Naples Progressive Gymnastics Center to the east, Pine Ridge Road to the south and vacant land to the west. III . PROJECT DESCRIPTION: The petitioner is requesting a planned unit development amendment to the "Cypress Glen PUD" , to reduce density for 9 . 4 to 7 units per acre to comply with the comprehensive plan. The PUD consists of 29 . 67 acres of land; 2 . 7 acres consist of lakes, 0 . 52 acres are for an oak hammock, 9 . 88 acres of cypress slough, 0 . 28 acres will be reserved for recreation area, 5 . 3 acres will be used for buildings, 6 . 4 acres will consist of pavement and 4 . 59 acres will be for pervious areas . Plan of Record: Water Management: Cypress Glen revised PUD Master Plan, prepared by Enviroscape, dated 12/12/91, five revisions. Environmental: Cypress Glen EIS supplement prepared by Craig Schmittler of Wilson, Miller, Barton & Peek, Inc. , dated 5/5/1992 . IV. STAFF COMMENTS: Water Management: The water management system for this project is being divided into three (3) sub-basins . Sub-basin 1 consists of the upland area just east of the cypress slough. Sub-basin 2 is the upland area west of the cypress slough and sub-basin 3 is the cypress slough. EAB Meeting 9/2/1992 PUD-87-18 (1) Page 2 Sub-basin 1 is proposed to have a water management system consisting of two lakes which have been sized to handle the runoff generated by a 25-year, 3-day duration storm event. The runoff will be conveyed to the lakes through swales and/or pipes. The lake located on the north side of property will discharge via a spreader swale into the slough. The lake on the south side will have a three (3) inch bleed-down mechanism which will be directed into the Pine Ridge Road swale. Sub-basin 2 contains approximately 2 . 5 acres of area, and due to the small amount of impervious surface (±1. 70 acres) and the separation from Basin 1 by the cypress slough the drainage will be designed for water quality only and it will discharge into the cypress slough through a spreader swale. Sub-basin 3 which encompasses the 9 . 88 acres of cypress slough will remain in its natural state and it will continue flowing in a southerly direction into the Pine Ridge Road swale. There will be a road built across the cypress slough which will incorporate properly sized culverts in order to maintain historical flow of the area. The discharge from Basin 1, will be limited to 0 . 06 cfs/acres or to the minimum size bleeder in accordance with Ordinance No. 90-10 and South Florida Water Management District rules. The water management system meets all the requirements for water quality and water quantity in accordance with South Florida Water Management District rules . Environmental: The petitioner proposes a density reduction and associated configuration changes to the PUD and Master Plan. The areas proposed for environmental preservation have either remained unchanged (Oak Hammock) or increased slightly in size (Cypress Slough) . The only major impact to the slough is a single access roadway, along the northern boundary of the property, which cuts across the slough. Best engineering principles, including use of culverts shall be utilized to ensure continued sheet flow within the wetland system. An updated cursory wildlife survey was conducted between March 24 , 1992 and April 2 , 1992 to determine the status of listed species on the site. No listed species were observed on the upland portion of the project. No listed animal species were observed in the wetland area; listed plant species (butterfly orchids, twisted air plants) shall be retained within the preserved slough.

STAFF COMMENTS: Engineering/Water Management/Environmental: Southwoods PUD is a proposed 400 site TTRV project which may include a clubhouse, recreational facilities, accessory uses, a cypress preserve and a lake. Of the 101. 3 acres, 92 . 3± acres constitute the water management basin. Excluded are 4 . 8 acres of cypress preserve and 4 . 2 acres of road/utility easements which are located outside of the water management isolation berm. The entire water management basin drains to a 34 . 9 acre lake which discharges to the south via a control structure that is set at 2 . 5 NGVD. The stormwater will be directed to the lake through a system of rear yard swales, roadside swales, and catch basin and piping networks . The 34 . 9 acre lake is designed in accordance with the Settlement Agreement. The maximum depth of 20 ft. is allowed under Section 3 . 5 of the Land Development Code for Commercial Excavations. A littoral shelf equal to 10% of the shoreline shall be provided. The Collier County Transportation Department will perform a road impact analysis for this project and calculate the appropriate road impact fees. The control elevation equals the permitted control elevation of the Marriott golf course development immediately south of Southwoods. The peak 25 year stage is 4 . 92 NGVD and the peak 25-year discharge rate is 11. 23 cfs. The 100-year stage is 5 . 40 NGVD. Natural drainage of the site is in a northeast to southwest direction. Sheetflow from the north flows across the property and is collected by a ditch located in the Championship Drive right-of-way. This interceptor ditch discharges south and west via the S.R. 951 right-of-way ditch and a drainage pipe under Championship Drive discharging in Marco Shores PUD. Elevations at the site range from 2 . 3 ft. to 3 . 8 ft. above mean sea level. Most of the site averages 3 . 0 . A berm along the north property line will divert around the site the off-site flow that presently enters the site from the north. An on-site swale will be constructed along the east property line that diverts run-off around the east side of the site to the inceptor ditch located along the south property line. The diverted run-off will ultimately discharge through cross-drains underneath Championship Drive and flow southwesterly as it did prior to development. EAB Meeting 9/2/1992 PUD-92-6/EXC. 59 . 228 Page 3 The subject property is entirely within the boundaries of lands deemed "Development Areas" by the Stipulation for Dismissal and Settlement Agreement, dated July 20, 1982 , between Deltona Corporation, various agencies of the State of Florida, conservation intervenors and Collier County. To conform with the Settlement Agreement, post-development discharge shall not exceed pre-development rates for the 25-year/3-day storm and off-site drainage entering a development area must be collected and conveyed via systems that are independent or isolated from the internal drainage systems. Off-site drainage systems and internal drainage systems may share spreader waterway outfalls. This project meets South Florida Water Management District rules for water quality and water quantity. V.

Date roject Review Serv; ces Manager COLLIER COUNTY TRANSPORTATION SERVICES "STANDARD CONDITIONS" EXCAVATION PERMIT APPLICATIONS INVOLVING OFF-SITE REMOVAL OF MATERIAL The intent of these "Standard Conditions" are to provide excavation permit applicants a summary of conditions which may affect their projects and which should be taken into consideration during all stages of project development: 1. Haul routes between an excavation site and an arterial road shall be private with property owner(s) approval or be a public collector road built to standards applicable to handle the resulting truck traffic. Where residential areas front collector roads, appropriate turn lanes, buffer and bikepath shall be required as minimal site improvements and if recommended for approval, shall be so with the condition that the Transportation Services Administration reserves the right to suspend or prohibit off-site removal of excavated material should such removal create a hazardous road condition or substantially deteriorate a road condition; such action by the Transportation Services Administration shall be subject to appeal before the Board of County Commissioners. 2 . Haul routes utilizing public roads shall be subject to road maintenance and road repair or an appropriate fair share by the permittee in accordance with Excavation Ordinance No. 91-102 and Right-of-Way Ordinance No. 82-91. 3 . Off-site removal of excavated material shall be subject to Ordinance No. 85-55 (Road Impact Ordinance) . A traffic and road impact analysis shall be made by the County to determine the effects that off-site removal of excavated material will have on the road system within the excavation project' s zone of influence. If appropriate, road impact fees in accordance with Ordinance No. 85-55 shall be paid prior to the issuance of an excavation permit. 4 . The Transportation Services Administration reserves the right to establish emergency weight limits on public roadways affected by the off-site removal of excavated material; the procedure for establishment of weight limits shall be the presentation of an applicable resolution before the Board of County Commissioners. Should weight limits be instituted, the permittee shall be responsible to implement measure to assure that all heavy truck loadings leaving the permit' s property conform to the applicable weight restriction. 5. The Excavation Performance Guarantee shall apply to excavation operations and also the maintenance/repair of public roads in accordance with current ordinances and applicable permit stipulations. 6. Based on soil boring information per Ordinance No. 91-102 , a blasting permit may be appropriate. Should a blasting permit application be submitted and should residential areas exist within one mile of the excavation site, the County reserves the right to deny a blasting permit based on concerns for off-site impacts from blasting at an excavation site. Should a blasting permit be considered and approved, the minimum conditions of approval in addition to conditions per Ordinance 88-12 are as follows: A. Structure inventory/monitoring and applicable property owner release as required by the County Engineer. B. Security bond applicable to private property damage acceptable to the County. C. Control of size/depth/number of charges per blast by the County Engineer. D. The right of the County to suspend and/or revoke blasting permit authority should be determined that blasting activities are creating unacceptable off-site conditions either in terms of private property damage and/or related physical effects of blasting operations. 7 . No excavation permit shall be issued until receipt of a release from the Transportation Services Administration applicable to proper mitigation of off-site impacts, meeting of applicable provisions of Ordinance No. 82-91, Ordinance No. 85-55, and Ordinance No. 88-12 .

Environmental: Environmental Impact Statement, prepared by Mr. Jack L. Abney, Wilson, Miller, Barton, & Peek, Inc. , revised June 3 , 1992 . IV. STAFF COMMENTS: Water Management: This project lies within the Main Golden Gate System and is part of the Main Golden Gate Canal Sub-basin. The proposed surface water management system will consist of lakes and detention areas to provide the required storage volume. The surface waters will be directed to the storage areas by storm sewer networks, swales and overland flow. EAB Meeting 9/2/1992 PUD-92-4 Page 2 The project is divided into two inter-connected basins. Basin 2 , the southern basin, will cascade into Basin 1, the northern basin. The control elevations for Basin 1 and 2 are 7 . 0 ft. NGVD and 7 . 5 ft. NGVD, respectively. The project ' s control structure is located in Basin 1 and consists of a circular bleed-down orifice at control elevation 7 . 0 ft. NGVD and a rectangular overflow orifice at crest elevation 8 . 6 ft. NGVD. The project will outfall to the Golden Gate Canal. Currently the northern quarter of the site sheetflows directly into the canal. The remainder of the site first sheetflows into the undeveloped property to the south then flows westerly to the drainage easement that lies along this projects western boundary, then flows into the canal . The average grade on-site is approximately 11 . 4 ft. NGVD. The post-development discharge rate for this project will equal the pre-development discharge rate of 0. 15 cfs/acre. This project meets the South Florida Water Management District rules for water quality and water quantity. Environmental: The property has been classified as 7 . 2 acres herbaceous range land, 28 . 6 acres palmetto prairie, 37 acres pine flatwoods (xeric) and 1. 4 acres melaleuca. A population of gopher tortoises (Gopherus polyphemus) exists within the palmetto prairie. A total of 32 burrows were observed including active, inactive and abandoned. The burrows were found in two groups on the western three-fourths of the site. They were monitored for two weeks during which time it was determined that eleven burrows showed evidence of activity. The petitioner proposes retaining the gopher tortoises on site. Florida Game and Fresh Water Fish Commission has notified Staff and the petitioner of a red-cockaded woodpecker (Picoides borealis) colony on property to the south, and recommends retention of foraging habitat on site. To meet the preservation requirements in the Collier County Land Development Code the petitioner has proposed retention of twenty-five percent (25%) of each site as it applies for an individual site development plan. A portion of the site lies within ground water protection zone W-4 of the Florida Cities Wellfield. There are no jurisdictional wetlands on site. EAB Meeting 9/2/1992 PUD-92-4 Page 3 V. RECOMMENDATIONS: Staff recommends approval of Planned Unit Development Petition PUD-92-4 "Golden Gate Health Park" with the following stipulations : Water Management: 1.
