REQUESTING: A zoning change from A-2 to PUD/A PUD amend- ment to Naples Research & Development Park Page 2 r. ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 COMMENTS: This Petition was administratively approved by NRMD. Dr . Benedict noted that the NRMD approval, as contained in the Staff Report, indicates that . . . . the petitioner in designating 1. 0 acre forested area as a preserve" , and questioned whether this is an additional stipulation? Mr . Edwards stated that the 1 acre preserve is located in the rezone area, and was not included in the original PUD, or in the origi- nal stipulations, noting that Staff is in agreement with this designation. ***** ITEM: Discussion - Landscape Committee recommen- dations for site development plan review for Standard Stipulation No. 2. COMMENTS: Ms. Muldoon began a review of subject item at this point in the meeting, but it was con- tinued to the end of the meeting, as so noted in the minutes. ***** PETITION NO. R-88-15C/PU-88-15C FILED BY/FOR: Anthony P. Pires, Jr . of Woodward & Woodward, P.A. , representing Gulfside Marketing, Inc. , Clyde Quinby, Trustee REQUESTING: A zoning change from A-2 to RSF-3 , a provi- sional use 7. 11b (3 ) of RSF-3 for a clubhouse and tennis courts, and a provisional use 8 . 10b for essential services (sewage treatment plant, water treatment plant) , "Wyntree" Subdivision COMMENTS: Mr . Dan Brundage of Agnoli , Barber & Brundage, Inc. stated that basically, the Staff Report recommends approval of subject project, but noted that during the process of discussions with Staff, questions were raised regarding the effect that the project may have on the Coral Reef Aquifer . He indicated that these Page 3 • ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5 , 1988 questions were addressed in his letter dated September 15, 1988. With regard to the landscape requirement, Mr . Brundage indicated that he is requesting that the 75% groundcover used for native landscaping, be reduced to 60%. He stated that the 75% will create an unnecessary burden on the project. Ms. Stevens advised that the subject property has been previously used for potato farming for the past 10 years, and ditches and berms still remain on site. She stated that the entire parcel has been cleared of native trees and shrubs for many years, and there are various grasses and annuals found on site. She indicated that the primary NRMD concern is the affect that the land use will have on the Coral Reef Aquifer , but noted that these questions have been adequately addressed in Mr . Brundage' s correspondence dated September 15 , 1988 . Ms. Stevens noted that NRMD recommends appro- .-. val of this Petition, subject to Standard Stipulations 2-4 (noted as 1-3 below) , and the additional stipulation (No. 4) , regarding the site landscaping. STIPULATIONS: 1. Native species shall be utilized, where available, to the maximum extent possible in the site landscaping design. A landscaping plan will be submitted to the Natural Resources Management Department and the Community Development Division for their review and subject to their approval . This plan will depict the incorporation of native species and their mix with other species , if any. The goal of site landscaping shall be the re-creation of native vegetation and habi- tat characteristics lost on the site during construction or due to past activities. 2. All exotic plants, as defined in the County Code, shall be removed during each phase of construction from development areas , open Page 4 ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 space areas, and preserve areas. Following site development, a maintenance program shall be implemented to prevent reinvasion of the site by such exotic species. This plan, which will describe control techniques and inspec- tion intervals, shall be filed with and sub- ject to approval by the Natural Resources Management Department and the Community Development Division. 3 . If, during the course of site clearing, exca- vation, or other constructional activities, an archaeological or historical site, artifact, or other indicator is discovered, all develop- ment at that location shall be immediately stopped and the Natural Resources Management Department notified. Development will be suspended for a sufficient length of time to enable the Natural Resources Management Department or a designated consultant to assess the find and determine the proper course of action in regard to its salvageabi- lity. The Natural Resources Management Department will respond to any such notifica- tion in a timely and efficient manner so as to provide only a minimal interruption to any constructional activities. 4 . The petitioner shall incorporate a large per- centage (at least 75%) of native species into the site landscaping to help restore the biological integrity of the area which has been lost through consecutive years of agri- cultural use. Ms Stevens noted that the 75% requirement as indicated in Stipulation No. 4 above was suggested because there are no native trees or shrubs on the site, and the Petitioner has stated a desire to restore the biological integrity of the area. She noted, however , the EAC may evoke this, if so desired. Dr . Benedict indicated that reference was made to a memo from Environmental Science and Pollution Control Director Lorenz , in Mr . Brundage ' s letter , noting that it is not included, and questioned whether copy is Page 5 • �..� ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 available, or if Mr . Lorenz could recall its content? Mr . Brundage provided a copy of the memorandum for Dr . Benedict' s review. A discussion took place regarding the required level of native vegetation, and Dr . Benedict stated that it should be consistent for everyone. Dr . Snyder stated that Standard Stipulation No. 2 indicates that "Native species shall be utilized, where available, to the maximum extent possible in the site landscaping design" , and he feels that the petitioner is being asked to do as much as is humanly possible. Mr . Below commented that he believes the landscaping should be in accordance with Stipulation #2, noting that until such time the language is changed, he believes the issue could be challenged. Mr . Lorenz indicated that this topic is part of the discussion Ms. Muldoon will brief the Council on, later in the meeting. He noted that Staff has a problem with that particular stipulation when it comes down to reviewing the plans and specs relating to landscaping. He advised that there is no definition as to "the maximum extent possible. Dr . Benedict advised that when Stipulation No. 2 was written a few years ago, it was understood that soon, thereafter , an Ordinance would be adopted that would be specific, adding that he would like to see Staff come back with specific comments relating to the landscaping. There were no speakers, either for or against subject Petition. MOTION: Made by Ms. Kurgis to recommend approval of Petition R-88-15C/PU-88-15C, subject to the Stipulations as stated above, amending Stipulation No. 4 to read ',The Petitioner Page 6 ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 shall incorporate at least 60% of native spe- cies into the site landscaping, subject to review and approval by NRMD " Seconded by Mr. Below. Carried unanimously PETITION NO. ST-88-15C FILED BY/FOR: Robert A. Lee, Trustee REQUESTING: A Special Treatment Permit for a proposed boat dock for a single-family residence. COMMENTS: Ms. Muldoon advised that on September 20 , 1988 , she inspected the site with Jim Beever of the Florida Department of Natural Resources. She stated that the Petitioner is proposing to construct a boat dock approxima- tely 54 ' long and 4 ' wide. She noted that approximate water depths are from 4-5 ' . She noted that the Petitioner is required by DNR to lengthen the dock 20 ' to minimize prop dredging and impact on shallow-water benthos . She indicated that the extension of the dock will require that the Petitioner obtain a boat dock extension through the County, and he must also apply for an Army Corps permit. Ms. Muldoon provided a slide presentation of subject parcel for the proposed dock, noting that it will not be constructed at the mouth of the lagoon, should it once again open up. Mr . Below stated that it appears the proposed dock will be located where there was a beach when the Pass was open, adding that if the configuration went back to where it originally was, the dock will be attached to land. Mr . Lee noted that the shore line has not moved more than 10 ' in the past 11 years . There were no speakers, either for or against subject Petition. MOTION: Made by Dr. Benedict to recommend approval of Petition ST-88-15C, subject to the Stipulation as noted below. Seconded by Mr. Below. Carried unanimously. Page 7 • ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 STIPULATION: 1. The Petitioner must obtain all the correct permits from other state, federal, and local agencies, and must adhere to all standards mandated by them in construction of the pro- posed dock. ***** ITEM: Landscape Committee Recommendations for Site Development Plan Review For Standard Stipulation No. 2 COMMENTS: Ms. Muldoon advised that Acting Community Development Administrator 011iff spoke to her in July regarding difficulties that the Landscape Architects were having with the 60% criteria she had set for the total plants. She noted that he had asked her to present this problem to the EAC, and request that the review process be changed, which would include the entire area, and suggested that the stan- dards be set in the language contained in the Stipulations. She stated that she attended the Landscape ^ Ordinance Committee Meeting on August 30 , 1988, to discuss the difficulties of the review process, and noted that the Committee is in the midst of rewriting the Landscape Code, and because these ideas will be incor- porated into it, they are looking for a "quick fix" of the review process, rather than rewriting the entire stipulation. The Committee has suggested the review of only the trees and understory, and excluding groundcover . She stated that basically, both the methodology of review and the rewriting of the stipulation needs to be accomplished. She indicated that the change in the Landscape Ordinance will be in final form in March, but adoption of the Ordinance by the Board of County Commissioners will most likely not take place until 4-6 months after that. Mr . Below noted that the EAC needs to decide what percentage should be adhered to, noting that the Standard Stipulation, as it currently reads, is too vague, and is unenforceable. He indicated that after the percentage is deter- Page 8 ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 mined, it would be appropriate for Ms . Muldoon to review the total landscape plan, and then apply the percentage to the total area . Dr . Benedict indicated that he would like to see Ms. Muldoon come back to the EAC with a rewritten interim standard. He further indi- cated that Dr . Snyder knows more about native vegetation than the other members of the EAC, and suggested that they meet. Dr . Snyder questioned whether the system Ms . Muldoon has been using during the past two years was a workable one? Ms. Muldoon replied negatively, noting that the landscapers prefer that the evaluation of plants be done by area, rather than by num- bers, adding that they dislike using native material, since they feel they do not provide enough color , they are not pretty, tend to be sparsely vegetated, etc. She noted that people generally do not want to change what they have been doing for a long time, but indicated that there must be a balance between what the landscapers want, and what the biolo- gists want. In answer to Dr . Benedict, Ms. Muldoon stated that Anne McCoy, landscape architect, is willing to interact with her on this subject, and she feels that the two of them can arrive at something that will be amenable to both landscape architects and biologists , during the interim period. Dr . Benedict indicated that if Ms. McCoy is willing to work with Ms. Muldoon, he believes that interim standards and guidelines could be used to rewrite the Stipulation. He suggested that other counties be contacted to learn how they handle similar procedures. He stated that after the revisions have been made, Ms. Muldoon present them to the EAC, and not wait for the Landscape Code. MOTION: Made by Dr. Benedict that Staff be directed to work with Ms. McCoy, landscape architect, to revise the language in Standard Stipulation Page 9 ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5, 1988 No. 2, and submit the recommendation to the EAC for review. Seconded by Mr. Below. Carried unanimously. ***** ITEM: Addendum - Pelican Bay COMMENTS: Mr . Below advised that it came to his atten- tion that Pelican Bay is planning additional development in the area that the EAC pre- viously identified as a unique turkey oak area, noting that they plan to dispose of 1/3 of that area. He stated that he feels this area needs to be preserved, and questioned what can be done? Natural Resource Technician Burch stated that subject area is being platted, and parts of the turkey oak hammock will be sold into lots, and a portion will be preserved. Dr . Benedict indicated that he recalls discussions regarding the plat, and Pelican Bay was going to do what they could to pre- serve it, before they moved on to the next plat. Planner Cacchione advised that the area where turkey oaks exist is designated on the Pelican Bay Plan as Group IV Housing. She noted that the developers worked with Dr . Proffitt in the past to establish boundaries of the turkey oak area to be preserved, and they are in the pro- cess of continuing to plat that area. She stated that she and Mr . Burch will be meeting with the parties next week to review the area to the north that is to be platted, and the area that is to be preserved as the turkey oak area . ***** Dr . Benedict stated that he is curious about the EAC Ordinance, i .e. establishing new pro- cedures and meeting monthly, etc. , and questioned the status of it? Page 10 M ENVIRONMENTAL ADVISORY COUNCIL OCTOBER 5 , 1988 Mr . Burch noted that he recently found a copy of the proposed ordinance, which was buried in the shuffle, adding that he forwarded same to the County Attorney' s office for review. ***** There being no further business, the meeting was adjourned by Order of the Chair .

Reynolds , of Wilson, Miller , Barton, Soll , and Peek , Inc ' , representing Harper Brothers, Inc . ; requesting a provisional use "a" of the " I " zoning classification for an asphalt plant and material storage. Petitioner requests a provisional use to build an asphalt plant and on site storage of material for this activity. The area has been previously altered , with cleared areas still in evidence. Vegetation consists of a slash pine ( Pinus elliottii var . densa) canopy and groundcover consisting of weedy, early '0-4\ successional , disturbance colonizers. Melaleuca (Melaleuca quinquenervia> and cabbage palm ( Sabal palmetto ) make up the sparse understory. According to DER, the proposed plant design and emission controls, consisting of a baghouse and stack , are the most effective for controlling particulate emissions. Other pollutants that may be produced by this activity, such as nitrogen and sulfur oxides, are usually absorbed within the aggregate or are trapped in the baghouse. The plant will have to meet state and federal regulations concerning particulate emissions. NRMD administratively approves petition PU-88-17C subject to the four standard stipulations as adopted by EAC on 4/1 /87. ENVIRONMENTAL RESOURCES STAFF REPORT ,..-.. FOR EAC MEETING 11/2/88 Petition: PU-88-20C: Joseph S. Boggs of Bruce Green and Associates, Inc. , representing Lee Williams; requesting a provisional use 8. 10 b of MHRP (Mobile Home Rental Park ) for a sewage treatment plant. Considerations: The subject property is a 4.34 acre parcel (387' x 485' ) located to the south of the Hitching Post Mobile Home Park and to the west of Barefoot Williams Road (S33, 1505, R26E) . An existing sewage treatment plant abuts the subject property on its southern boundary, and a canal coincides with the western boundary of the property. The site is currently zoned for Mobile Home Rental Park use (undeveloped ) . The petitioner is requesting approval for a sewage treatment plant to serve the Mobile Home Park, and as a permitted provisional use of the existing zoning. The site was inspected on October 11 , 1988 by Andrea Stevens (Environmental Resources Staff) . The western and northern .-....„ boundary areas of the site, and some interior areas are heavily infested with noxious exotics (Melaleuca and Brazilian pepper ) . Otherwise, the parcel supports widely scattered slash pine (average diameters of 6" ) with a graminoid groundcover. It is evident that the native habitat on the parcel has become impacted by past activities.

ENVIRONMENTAL RESOURCES MANAGEMENT MEMORANDUM TO: EAC Members FROM: Earlene Weber Secretary I DATE: October 27 RE: Staff Report - PU-88-16C The staff report for petition PU-88-16C will be hand delivered on Friday October 28, 1988. If you have any questions, please contact me at 774-8454. /'••. ENVIRONMENTAL RESOURCES MANAGEMENT (ERM) STAFF REPORT FOR EAC MEETING 11/2/1988 Petition: PU-88-16C: Robert K. Lockhart, P.E. of Wilson, Miller, Barton, Soil & Peek, Inc., representing William Higgs; requesting a provisional use "b" of A-2 for earth mining. Considerations: Petition PU-88-16C (the Higgs-Harper PU) is a modification of an existing approved provisional use petition (PU-81-20C) allowing earth mining; present zoning is A-2 (PU-2). The existing mine is in the northeastern sector of the intersection of I-75 and S.R. 951 (S35, T49, R26). The area is surrounded on the north and east by transitional upland/wetland forest habitat, dominated by slash pine (Pinus elliottii) and bald cypress (Taxodium distichum); infestation by melaleuca (Melaleuca quinquinervia) is moderate. The southwestern boundary is the County landfill access road, adjacent to 1-75. The site was inspected by James N. Burch (ERM) on 24 October, 1988. The provisional use modification that has been proposed would allow the existing earth mining operation to increase the depth of the 70 acre excavation from the permitted 20 feet to a depth of 30 feet, and hauling of fill off site. Most of the site has been excavated or is in preparation for excavation, leaving little viable terrestrial habitat within the project limits. According to the petitioner's agent, an 11.3 acre wetland area located near the southwestern border has been designated as a preserve area by the petitioner. Environmental Resources Management (ERM; formerly Natural Resources Management Department) has concerns about possible effects on ground water and surface water in the area; therefore an Environmental Impact Statement (EIS) was required, with emphasis on water quality in and around the pit. ERM staff also raised concerns about possible blasting and fracturing of the confining layer that defines the upper limit of the Lower Tamiami Aquifer. Current permits for the mining operation will allow further blasting while removable overburden exists in the mine. According to ERM Hydrogeologist, Terri Newman and South Florida Water Management District's Log 86-1 report, data in our area, from tests for natural gamma radiation in the substrate, suggest that the depth of the dense, less permeable confining layer is irregular, but is probably 40 feet or more below the ground surface. The proposed mining and blasting is unlikely to damage the subtending confining layer. Other concerns include possible compromises to water quality and the project's proximity to wellfields, intrusion by subsurface trapped saltwater, and possible effects on migration of water from the nearby County landfill. According to ERM Staff Report PU-88-16/C EAC Meeting 11/2/88 Page -2- Specialist Ray Smith, the nearest wellfield is the Florida Cities Golden Gate Wellfield nearly two miles northwest of the project (S27, T49, R26); according to Mr. Smith, this project is unlikely to compromise the quality of water currently being extracted from this wellfield. According to the petitioner, the operation will be a wetmining project, and will not require dewatering; this will result in minimal effects to the ground water table. This suggests that there will be little or no effect on ground water by intrusion or effects on ground water migration. Chemical testing of ground water in and around the borrow pit will be done at the direction of the Water Management Director by authority of County Ordinance 88-26. Recommendations:1 With the previous points in consideration, ERM recommends approval of' petition PU-88-16C with the following suggested stipulations: 1. All exotic plants, as defined by County Ordinance 82-37 shall be removed from the preserve area, and any other native habitat within the project limits, upon the initiation of the proposed mining activity.

Burch Chief Environmental Specialist,ERM DATE: October 11, 1988 RE: PU-88-16C: Robert K. Lockhart, P.E. of Wilson, Miller, Barton, Soll, & Peek, Inc. , representing William Higgs; requesting a provisional use "b" of A-2 for earth mining. Petition PU-88-16C (the Higgs-Harper PU) is a modification of an existing approved provisional use petition (PU-81-20C) that allows earth mining in the northwestern sector of the intersecion of 1-75 and S.R. 951 (S35, T49 , R26) . The modification that has been proposed would allow the existing earth mining operation to increase the depth of the 70 acre excavation from the permitted 20 feet to a depth of 30 feet. According to the petitioner, the proposed modification will not significantly alter the terrestrial communities that surround the borrow pit. However, Environmental Resources Management (ERM; formerly Natural Resources Management Department) has concerns about possible effects on ground water and surface water in the area; therefore an Environmental Impact Statement (EIS) was required, with emphasis on water quality in and around the pit. The petitioner has indicated that no dewatering of the operation will take place, and that the proposed mining will not affect the water table in this area. Chemical testing of ground water in and around the borrow pit will be done at the direction of the Water Management Director. As the area is presently the site of an earth mining operation, the proposed modifications appear to be of small consequence to the surrounding upland and wetland systems. With the above points in consideration Environmental Resources Management administratively approves petition PU-88-16C. �~ � /- TO Jim Burch Chief Environmental Specialist FROM: Keith Edwards (:1 '!_'' ''': ) Environmental Specialist DATE: October 12, 1988 RE: Petition R-87-43C; J.

Considerations: The subject property is a 31 .9 acre parcel located on the northeast corner of U.S. 41 and Immokalee Road (C-846) (522, 1488, R25E) . Lands to the east of the parcel are undeveloped pine woodlands and xeric palmetto habitats (zoned A-2) . A lake is located to the north of the parcel , as well as open upland areas (also zoned A-2) . The property was inspected on October 11 , 1988, by Andrea Stevens (Environmental Resources Staff) . The petitioner is requesting a rezoning of the parcel from A-2 to PUD to allow for a Community Commercial Shopping Center. A 70% impervious area is proposed for the development. The average elevation of the site is 8 feet NGVD. The only wet area on the parcel is a small man-made lake adjacent to the eastern property boundary. The littoral areas of the lake have become overgrown with cattails (Typha spp. ) . The exotic Brazilian pepper (Schinus terebinthifolius) has become established along lake shore areas. The remainder of the site is dominated by drier habitats. The southern half of the parcel supports a pine woodlands habitat with a palmetto (Serenoa repens) understory. Slash pines (Pinus elliottii) have 6"-8" diameters, although several trees with 12"- 14" diameters were noted. In addition to the dense palmetto growth in this habitat, shrub layer vegetation includes rusty lyonia (Lyonia ferruqinea) , wax myrtle (Myrica cerifera) , dog fennel (Eupatorium capillifolium) , and gallberry ( Ilex qlabra) . Groundcover consists of various grass species, and an occasional Hypericum spp. , but mostly just scattered pine needles. In the southwest corner of the parcel , the pine woodlands have become infested with the exotic melaleuca (Melaleuca quinquenervia) . Also, the exotic Brazilian pepper (Schinus terebinthifolius) is encroaching along the southern and part of the western property boundaries, adjacent to heavily used roads. Moving north across the parcel , the landscape becomes dominated by open palmetto areas. Small pines ( 10-15 feet in height) are found infrequently in this habitat. Pennyroyal (Piloblephis rigida) , prickly pear cactus (Opuntia spp. ) , love vine (Cassytha filiformis) , as well as rusty lyonia and wax myrtle were noted among the palmettos. In addition, the habitat supports several small oaks (Quercus spp. , 3"-4" in diameter and Staff Report R-88-21C .0". EAC Meeting 10/19/88 Page 2 10 feet in height) , and the area may provide habitat for the gopher tortoise, which is a protected species in this state. Near the northeast corner of the site, several open sandy patches are evident. Recommendations: The Environmental Resources Staff recommends approval of petition R-88-21C subject to the following stipulations: 1-4. Standard Stipulations 1-4 as adopted by the EAC on 4/1/87. 5. The petitioner shall arrange for a gopher tortoise survey to be completed by knowledgeable personnel . The necessary procedures for gopher tortoise relocation (Florida Game and Fresh Water Fish Commission) shall be followed in the event a gopher tortoise is found. Prepared By: 4, , ,. .
