She requested Members review the forms and provide additional comments to her. Mr. Mulhere arrived at 4:15pm B. Review of three Out of Cycle LDC Amendments [Caroline Cilek] Ms. Cilek presented the following three proposed LDC Amendments for consideration: LDC SECTION(S): 1.08.02 Definitions - 5.05.05 Automobile Service Stations CHANGE: The proposed amendment to LDC section 5.05.05 Automobile Service Stations establishes that automobile service stations shall be limited to eight fuel pumps when located within 300 feet of residential property; however, a greater number of fuel pumps may be sought through the conditional use process or as part of a Planned Unit Development. In addition to the Findings established in LDC section 10.08.00, the proposed amendment establishes several considerations to be examined when evaluating compatibility and adverse impacts of the conditional use request. Ms. Taft reported she had a conflict of interest with the item and has filed Memorandum of Voting Conflict Form 8B with the necessary parties. The conflict arose after her participation in Subcommittee meetings where this item was reviewed. Ms. Cilek reported • The proposed amendment was prepared based on a July 8, 2014 directive to Staff from the Board of County Commissioners(BCC). • The changes outlined in Section 5.05.05.0 which would require establishments proposing more than 8 fueling pump stations being subject to conditional use standards. • The language for the proposed amendment was based on the BCC Executive Summary related to the item. The following concerns were identified by the Committee: • The distance requirement from fuel pump to residential uses is defined as the property line and this may not be practical given many of the properties in the County are multi unit residential tracts with outlying preserve areas or lot lines a vast distance from residential uses. • The proposed amendment includes regulating establishments that have non retail facilities which are not available to the public and questioned if this is one of the intended goals of the directive given the low intensity of the use. • The proposed amendment was spurned by one particular landowner who acquired the properties with constructive notice they abut a C-4 zoning district which at the time of purchase,permitted theses uses. 4 October 1, 2014 • The proposed amendment would negatively affect existing property owners who made previous business decisions based on zoning requirements by limiting"permitted uses"in the zoning districts. Mr.Brooker,Ms. Taft and Mr. Mulhere,Members of the Subcommittee reported the Subcommittee recommended the following: The proposal as drafted not be adopted, but that the comments and issues that have been raised are worthy of consideration and if the amendment were to be drafted not to include zoning districts C-4, C-5, and Industrial, then the amendment would be more worthy of consideration (see below). Comments and issues raised by the Subcommittee: 1. To address site design provisions within LDC section 5.05.05 be included in this amendment cycle, and if not, direct staff to include them in the next amendment cycle, including the following: a. Lighting, address lighting comprehensively as it relates to commercial use adjacent to residential b. Landscaping c. Branding and banding/color schemes for canopies/canopy, d. Increase the signage percentage 10%of the size of the canopy façade e. Bathrooms to be located inside the automobile service station building. 2. Recommend that staff to work with Sheriff's office to look at CPTED in the LDC. Additionally the following concerns were identified by the Subcommittee: • The threshold for additional regulation is the number of fuel pumps and it may be more prudent to develop a threshold based on consumer demand, i.e. total annual fuel output volumes, etc. • The C-4, C-5 and Industrial zones are established by regulation as zones where numerous high intensity uses are allowed such as supermarkets, automobile dealerships,pharmacies, etc. and County regulations should address impacts(exterior lighting, traffic, noise, emissions, etc.)of these uses holistically as opposed to a singling out a particular use. • This issue of Benzine emissions from fuel distribution sites arose and concern the studies used as a basis were outdated(2005) and the industry has developed standards to address these issues since this time. Speaker Dan Oberski,Trinity Commercial Group (Wawa,Inc.) addressed the Committee and recommended any proposed language be specific in nature so it is clear to affected parties how any standards will be regulated before and after purchase of a property. The large scale stations are beneficial in providing competition to the market and are highly efficient and clean operations regulated by corporate standards. Mr. Brooker moved to recommend the Board of County Commissioners not adopt the proposed amendment as drafted, but that the comments and issues raised by the Subcommittee as listed above are worthy of consideration and if the amendment were to be drafted to not include zoning districts C-4, C-5, and Industrial, the amendment would be more worthy of consideration. The basis for the action is as follows: 5 October 1, 2014 1. Concern that property rights will be taken as a conditional use is not by right. 2. Automobile Service Station—issue with definition and that it would apply to non retail establishments. 3. Measure the 300 distance from the pump to the face or the edge of the residential building. 4. Evaluate the 8 fuel pumps vs. the output of the gas stations. 5. Consider that the fewer fueling positions may result in a greater number of small stations. 6. The conditional use process discourages business and can be arbitrary and occasionally capricious. 7. Consider whether the amendment benefits a few to the detriment to the public at large. Second by Mr. Chrzanowski. Carried unanimously 11—0. Ms. Taft abstained. LDC Section(s): 2.03.01 —Agricultural Zoning Districts; 4.02.07 Standards for Keeping Animals and 5.04.05 -Temporary Events. Change: The proposed amendment seeks to clarify the process for raising hogs in the Estates and Agricultural zoning districts in relation to the County's 4-H youth development program. Ms. Cilek reported • The amendment is proposed as the result of a directive from the Board of County Commissioners following a Code Enforcement case. • The proposed amendment will make the activity an accessory use eliminating the current requirement of obtaining a special use permit. • It proposes standards for allowing youths to raise hogs as a temporary activity(a 16 week period),no more than 1 hog per child and no more than 2 hogs per acre. • Minimum requirements for structures associated with the activity(setback requirements, etc.) are proposed. • The program will be administered by the 4-H Youth Development Program. The Land Development Regulation Subcommittee recommended approval of the proposed text and identified that the following should be noted for consideration by reviewing entities prior to adoption: 1. There are lots in the Estate district that are below 1.25 acres, such as those that are 1.14 acres (75 feet wide, 660 feet depth). The proposed language would not allow for hogs to be raised on these lots in coordination with the 4H program. 2. Consideration should be given to recommending or requiring a 75 foot setback in the Estates district from a potable water well(including a neighboring well) in order to prevent the potential contamination of a well head. Further, there are a handful of smaller agricultural properties that are west of 1-75 which could potentially be used for the raising of hogs in coordination with the 4H program. Discussion occurred on if the Future Farmers of America has a similar program that should be included in the amendment. 6 October 1, 2014 Staff reported any Program under consideration for inclusion in the proposed amendment would have to be administered to the same standards as the 4-H program. Mr. Disney moved to recommend the Board of County Commissioners approve the proposed amendment as written and identified the following issues for consideration by the reviewing entities prior to adoption: 1. There are lots in the Estate district that are below 1.25 acres, such as those that are 1.14 acres (75 feet wide, 660 feet depth). The proposed language would not allow for hogs to be raised on these lots in coordination with the 4H program;2. Consideration should be given to recommending or requiring a 75 foot setback in the Estates district from a potable water well(including a neighboring well) in order to prevent the potential contamination of a well head). Second by Mr. Gentry. Mr. Disney moved to amend the motion to include the original motion and that the Future Farmers of America be incorporated into the proposed amendment should it be determined they have a program similar in nature to the 4-H Youth Development Program. Second by Mr. Gentry. Carried unanimously 12—0. LDC Section(s): 2.03.01 Agricultural Districts Change: The proposed amendment allows residents to grow fruits, vegetables and nursery plants for both personal consumption and off-site retail sale, such as at farmer's markets, pursuant to LDC Section 5.02.00, Home Occupations. Ms. Cilek provided an amendment proposed for LDC Section(s): 2.03.01 Agricultural Districts The proposed amendment allows residents to grow fruits, vegetables and nursery plants for both personal consumption and off-site retail sale, such as at farmer's markets,pursuant to LDC Section 5.02.00, Home Occupations. She noted: • The proposed amendment allows the growing of fruits, vegetables and nursery plants in the Agricultural Districts for off site sale of the products. • The Land Development Regulation Subcommittee recommended the proposed amendment be approved as written. Mr. Dunnavant moved to recommend the Board of County Commissioners adopt the proposed amendment as written. Second by Mr. Gentry. Carried unanimously 12—0. VII. Old Business A. Floodplain Management Update Ms. Cilek reported: • The County has not yet filled the position of"Floodplain Coordinator." • There are currently no changes proposed in the Floodplain Management Ordinance. • The Floodplain Management Committee is currently working on updating the Floodplain Management Plan. • The Resolution governing the Committee seeks to limit those with land development interests from serving on the Committee.

Non-potable irrigation water pipelines and fittings, except for service piping, shall be a minimum of four inches (4") in diameter, and have a minimum depth of thirty-inches (30") and a maximum depth of forty-eight inches (48") below finished grade. All potable water or non-potable irrigation water pipelines shall be constructed of ductile iron, HDPE, or PVC pipe, and shall utilize pipe meeting the requirements of the Technical Specifications. HDPE shall not be used for pipelines with service connections. Pipelines up to thirty inches(30") in diametor may be constructed of Fusible PVC. All pipe and pipe fittings shall contain no lead pursuant to the Reduction in Lead in Drinking Water Act. more than eight percent (8.0%) lead, and any solder or flux used shall contain no more than two tenths of a percent (0.2%) lead. All pipe and pipe fittings installed shall be color coded or marked in accordance with F.A.C. 62-555.320(21)(b)3. Specifications. Potable water pipelines shall be blue in color. Raw water pipelines shall be white in color. Non-potable irrigation, reclaimed, and reuse water pipelines shall be pantone purple in color. All buried water pipelines and mains, except those installed by horizontal directional drilling or jack-and-bore methods, shall be marked using metalized warning tape for HDPE and PVC pipe and non-magnetic for ductile iron pipe. The locator tape shall be placed in the pipe trench two feet (2') below grade or one-half the pipe's bury, whichever is less, and labeled "potable water" or"non-potable water" as applicable. Horizontal directional drilling shall include installation of at least two locating tone wires as described in the Technical Specifications. All water main aerial crossings shall be Pressure Class 350 flanged ductile iron pipe and shall be coated on the exterior using a suitable grade of appropriately colored, field applied (or factory applied with field touch-up as required) epoxy coating. Potable water mains shall be painted Federal Safety Blue. Raw water mains shall be painted white. Non-potable irrigation, reclaimed, and reuse water mains shall be painted Pantone Purple 522C. Specific colors shall be subject to approval of the County Manager or designee. All nuts and bolts used in aerial crossings shall be stainless steel. All canal, river, or creek crossings shall be aerial, unless otherwise approved by the County Manager or designee. Aerial crossings shall be designed to incorporate valves or other flow regulation devices in accordance with F.A.C. 62-555.320(21)(b). Aerial crossings shall be designed to maintain existing or required navigational capabilities within the waterway and to reserve riparian rights of adjacent property Owners. Submit aerial pipe and flange computations, including support and anchor design, for review. The submittal must be signed and sealed by a Florida registered Licensed Professional Engineer.

Section 1, Design Criteria, Page 3, text revisions in 1.2.2 1.2 Design of Pipeline Size and Location 1.2.2 Distribution System Layout G^ „New potable water distribution systems shall be designed as "looped" systems to avoid dead ends. A "looped" system should have two independent connections off the source main (unless served by a master meter). If two independent connections aren't possible, a stub out for future development in a location agreed to by the County shall be provided in an easement or ROW to the limits of the project. If changes in design during construction result in dead ends to any new or relocated water mains, such dead ends shall be connected to the nearest water main. In cases where no nearby water main is available, a County approved automatic flushing device shall be provided at each dead end of a water main and, if applicable, also near the mid-point of a looped water main unless the design engineer can provide information to confirm that the minimum residual chlorine will be maintained based on the predicted water consumption at the time of County acceptance of the water main. At no time shall a dead end serve more than 149 residential units. For phased projects, temporary automatic flushing devices can be relocated for future phases, if not conveyed to County. Section 1, Design Criteria, Page 5, text revisions in 1.3.1 1.3 Conflict Crossings 1.3.1 Subaqueous Canal Crossings All subaqueous crossings must be introduced/discussed at a plan Pre-Submittal Conference. It is important that representatives from the Water Department or Wastewater Department and GD€S-GMD be present for approval at the plan Pre-Submittal Conference.

Section 1, Design Criteria, Page 6, text revisions in 1.4 1.4 Fire Service Systems All private fire service systems for sprinkler systems, wet standpipe systems, and privately- owned or controlled distribution systems shall be installed with an appropriate backflow prevention device with a leak detection meter. The meter backflow device shall be sized by the Developer's Engineer and shall be purchased, owned and maintained by the private service owner. The COUNTY requires all privately-owned backflow devices to be certified at the time of installation and on an annual basis by a Certified Backflow Tester (University of Florida, TREED Center, or equivalent certification program). The results shall be submitted to the County Manager or designee. The County Manager or designee will require all privately owned metering devices to be certified for accuracy at the time of installation. Fire meter devices using a three quarter to two inch (3/" to 2") metering device shall be re-calibrated to manufacturer's specifications every five (5) years, replaced every ten (10) years, or replaced immediately upon meter failure. Fire meter devices greater than two inches (2") shall be re- calibrated to manufacturer's specifications every five (5) years and replaced immediately upon meter failure. The County Manager or designee will inform the owner by mail prior to the due date. Private owner(s) shall submit certification results to the County Manager or designee within sixty(60) days of the due date. Section 1, Design Criteria, Page 7, text revisions in 1.6.2 1.6 Water Services 1.6.2 Water Meters Water meters shall be properly sized, based on the total calculated service demand for water, according to the Collier County Water Meter Sizing Form (Appendix B). The properly sized water meter shall be installed according to specifications and standards. Any deviation from the determined meter size shall require an approved Deviation Request, if the motor is two inchoc (2")or largcr in cizo.

Section 2, Technical Specifications, 014500 "Quality Control", Pages 4 and 5, text revisions in 1.5.A.4. 1.5 QUALITY CONTROL A. Testing 4. Testing of Gravity Sanitary Sewer Lines a. Watertight Construction: It is imperative that all sewers and force mains, manholes, and service connections be built watertight and that the CONTRACTOR adhere rigidly to the specifications for material and workmanship. Since all of the water and sewage in the lines will be treated at the treatment plant, special care and attention must be given to securing watertight construction. After completion, the sewers or sections thereof will be tested and gauged. If infiltration or exfiltration is above the limits specified, the sewer construction work will be rejected. b. Cleaning: Exercise care during construction of the manhole to see that materials do not enter the sewer line. Keep the invert and shelf of the manhole clean of all mortar, broken brick, sand, or any other materials falling into the manhole. Immediately remove such material. Maintain this condition until final acceptance of the work. Prior to testing of gravity sanitary sewer lines, clean the lines using appropriate tools. c. Gravity Sewers - Visual Inspections: On completion of each block or section of sewer, or at such other times as the County Manger or designee may direct, the block or section of sewer is to be cleaned, tested and inspected. Each section of the sewer is to show, on examination from either end, a full circle of light between manholes. Each manhole, or other appurtenance to the system, shall be of the specified size and form, be watertight, neatly and substantially constructed, with the rim set permanently to design position and grade. All repairs shown necessary by the inspection are to be made; broken or cracked pipe replaced, all deposits removed and the sewers left true to line and grade, entirely clean and ready for use. d. Infiltration Limits: Provide the equipment necessary to check the lines for infiltration or exfiltration as directed by the County Manager or designee, before they are put in service. Infiltration in excess of fifty (50) gallons per day inch-mile of sewer will result in having the CONTRACTOR go over the lines, ascertain where the leakage exists, and repair the lines to the extent necessary to bring the infiltration down within acceptable limits. Observable inflow is not permitted. Page 42 of 48 e. Exfiltration Limits: The length of sewer subject to an exfiltration test shall be the distance between two (2) adjacent manholes. Close the inlets of the upstream and downstream manholes with watertight plugs and the test section filled with water until the elevation of the water in the upstream manhole is two (2) feet above the crown of the pipe in the line being tested, or two (2) feet above the existing groundwater in the trench, whichever is higher. A standpipe may be used instead of the upstream manhole for providing the pressure head when approved by the County Manager or designee. Measure exfiltration by determining the amount of water required to maintain the initial water elevation for one (1) hour period from the start of the test. The maximum allowable leakage, including manholes, shall be 50 gallon per inch for diameter per mile of pipe per day. f. Air Testing: Air testing shall be required if, in the opinion of the County Manager or designee, conditions are such that infiltration measurements may be inconclusive. Conduct the test in the presence of the County Manager or designee and conform to the following requirements: (a) Test pressure shall be 3.5 psi increased by the groundwater pressure above the top of the sewer. (b) Pressure loss from shall not exceed 0.5 psi during the required testing time. (c) Testing time in minutes shall be calculated as 0.625 x nominal pipe size (inches). g. Deformation Test (a) Deformation tests shall be performed on all gravity sewer lines. The test shall be conducted after the final backfill has been in place at least 30 days to permit stabilization of the soil-pipe system. (b) No pipe shall exceed a deformation of 5 percent. If deformation exceeds 5 percent, mechanical methods to correct deformation may be used. If mechanical methods are unsuccessful, the pipe shall be excavated. Replacement or correction shall be accomplished in accordance with requirements in the approved specifications. (c) The rigid ball or mandrel used for the deflection test shall have a diameter not less than 95 percent of the base inside diameter or average inside diameter of the pipe depending on which is specified in the ASTM Specification, including the appendix, to which the pipe is manufactured. The test shall be performed without mechanical pulling devices. Page 43 of 48 Proposed Revision to Section 2, Technical Specifications Proposed additions in text are noted in bold.
