The utilities included are those providing for, or related to: electrical power (including wiring to streetlights), telephone, potable & irrigation/re-use water, sewer, cable television, and gas. This section shall apply to all public utilities either proposing, or relocating existing, permanent facilities, infrastructure, or improvements within subdivisions or developments, including all cables, conduits, or wires forming part of an electrical distribution system, which includes all service lines to individual properties and main distribution feeder electrical lines delivering power to local distribution systems, but does not include or apply to wires, conduits or associated apparatus and supporting structures whose exclusive function is for the transmission of electrical energy between generating stations, substations, and the transmission lines of any other electric utility provider's systems. A. Appurtenances such as transformer boxes, pedestal mounted terminal boxes, meter cabi- nets, service terminals,telephone splice closures, pedestal type telephone terminals or other similar "on the ground" facilities normally used with and as a part of the underground distribution system may be placed above ground but shall be located so as not to constitute a traffic hazard. B. Public utility easements shall be coordinated with other appropriate public utility providers with verification of the creation or dedication of such easements provided to the County manager or designee before final subdivision plat and improvement plans approval. C. The installation of underground utilities or relocating existing facilities as prescribed by this section must also be in conformance with the respective utility's rules and regulations. D. Utility casings. Subdivisions or developments providing water services shall install no less than four-inch conduits to each alternate lot on the opposite side of the street from the main distribution line for each street prior to the completion of roadway construction or as required by applicable utility. Additionally, all casings for irrigation facilities, street lighting and other utility services such as electric,telephone, cable television,and the like shall be placed under all proposed streets prior to the completion of the stabilized subgrade. (Ord. No. 04-72, § 3.V) 6.01.02 Easements If applicable, easements shall be provided along lot lines or along the alignment of the improvements requiring easements in accordance with all design requirements so as to provide for proper access to, and construction and maintenance of, the improvements. All such easements shall be properly identified on the preliminary subdivision plat and dedicated on the final subdivision plat. A. Utility easements. 1. Utility easements no less than 10 feet wide, unless otherwise approved by the County Manager or designee pursuant to Chapter 10, shall be provided to accom- modate all required utilities to, across, or along lots and, where possible, shall be centered on lot lines with convenient access for maintenance. Utility easements Supp. No. 11 LDC6:3 COLLIER COUNTY LAND DEVELOPMENT CODE 6.01.02 A. 6.01.02 C. and drainage easements shall not be combined without prior approval of the County Manager or designee; drainage easements shall take precedence and be so noted on the final subdivision plat. 2. All utility easements for water and sewer facilities that will be conveyed to the Collier County Water-Sewer District shall be separately identified and dedicated on the final subdivision plat as"County Utility easement" (C.U.E.)and shall be a minimum of 15 feet wide unless otherwise approved by the utility division. Except when crossing other easements,such easements shall not be inconsistent with other existing utility easements, or later subjected to uses inconsistent with the use of the easement area for utility purposes unless otherwise approved by the County Manager or designee pursuant to the conditions in Chapter 10. B. Drainage easements. 1. Drainage easements shall be provided to accommodate open access at a width no less than a total of 10 feet. The actual size of the easement in excess of the 10 foot minimum shall be determined based on the hydraulic design of the flowway and the use of bank stabilization approved by the County Manager or designee or minimum side slopes at a four to one (4:1) ratio, without stabilization. 2. Where underground drainage structures are installed,the easement width shall be sized to accommodate construction, maintenance, and replacement of said struc- tures. In no case shall said easement be less than 15 feet in width, unless otherwise approved by the County Manager or designee pursuant to Chapter 10. 3. When a subdivision or development includes or requires access across canals, watercourses, water bodies, streams, drainageways, channels, naturally occurring wetlands (that are to be preserved), or the like, a drainage easement and adjoining maintenance/access easement shall be provided which conforms substantially to the lines of such watercourses unless otherwise approved by the County Manager or designee pursuant to Chapter 10. Maintenance and access easements for the subdivision's or development's approved water management system shall be created and sized in compliance with the rules and regulations of the South Florida Water Management District (SFWMD), as amended. For canals or waterways, maintenance/access easements shall be provided in accordance with requirements of the entity with responsibility for maintenance/access. Drainage easements shall be created to provide for the flow of surface waters from contributory areas. C. Protected/preserve area and easements.A nonexclusive easement or tract in favor of Collier County, without any maintenance obligation,shall be provided for all"protected/preserve"areas required to be designated on the preliminary and final subdivision plats or only on the final subdivision plat if the applicant chooses not to submit the optional preliminary subdivision plat.Any buildable lot or parcel subject to or abutting a protected/preserve area required to be designated on the preliminary and final subdivision plats, or only on the final subdivision plat if the applicant chooses not to submit the optional preliminary subdivision plat, shall have a minimum setback as required by the LDC, or other setback that may be approved as a deviation through the PUD approval process by the Board of County Commissioners from the boundary of such protected/preserve area in which no principle structure may be constructed. The required preserve principal structure setback line and the Supp. No. 11 LDC6:4 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.01.02 C. 6.01.05 A. accessory structure setback lines shall be clearly indicated and labeled on the final plat where applicable.Further,the preliminary and final subdivision plats, or only on the final subdivision plat if the applicant chooses not to submit the optional preliminary subdivision plat, shall require that no alteration, including accessory structures, fill placement, grading, plant alteration or removal, or similar activity shall be permitted within such setback area without the prior written consent of the County Manager or designee;provided, in no event shall these activities be permitted in such setback area within ten feet of the protected/preserve area boundary.Additional regulations regarding preserve setbacks and buffers are located in Chapters 4 and 10, and shall be applicable for all preserves, regardless if they are platted or simply identified by a recorded conservation easement.The boundaries of all required easements shall be dimensioned on the final subdivision plat. Required protected/ preserve areas shall be identified as separate tracts or easements having access to them from a platted right-of-way. No individual residential or commercial lot or parcel lines may project into them when platted as a tract. If the protected/preserve area is determined to be jurisdictional in nature, verification must be provided which documents the approval of the boundary limits from the appropriate local, state or federal agencies having jurisdiction and when applicable pursuant to the requirements and provisions of the growth management plan. All required easements or tracts for protected/ preserve areas shall be dedicated and also establish the permitted uses for said easement(s)and/or tracts on the final subdivision plat to Collier County without the responsibility for maintenance and/or to a property owners'association or similar entity with maintenance responsibilities.An applicant who wishes to set aside,dedicate or grant additional protected preserve areas not otherwise required to be designated on the preliminary subdivision plat and final subdivision plats, or only on the final subdivision plat if the applicant chooses not to submit the optional preliminary subdivision plat,may do so by grant or dedication without being bound by the provisions of this section. (Ord. No.05-27, § 3.LL;Ord. No. 13-56, § 3.X) 6.01.03 Soils The construction plans for the subdivision or development shall show the location and results of test borings of the subsurface condition of the tract to be developed. If the soil investigations reveal that the area contains hardpan, other nonpervious soils, peat, muck, or other unstable materials, the County Manager or designee shall require that adequate precautionary measures be included in the design and construction of the improvements to ensure that proper drainage and development of the area can be accomplished, in a manner which will prevent premature deterioration of the improvements. 6.01.04 Removal of Exotic Plants Required All prohibited exotic plants,as defined in section 3.05.00,shall be removed during each phase of construction from development areas, open space areas, and preserve areas pursuant to section 3.05.00. Following site development, a maintenance program shall be implemented to prevent reinvasion of the site by prohibited exotic species.This plan shall describe control techniques and inspection intervals, and shall be filed with, and approved by,the County Manager or designee prior to approval of the improvement plans and final subdivision plat. Flexibility, in the form of area tradeoffs or mitigation, may be allowed in the determination of areas within developments to be preserved. 6.01.05 Soil Erosion and Sediment Control A. Soil Erosion and Sediment Control Plan. For new and existing development and construction approved pursuant to the provisions of LDC sections 10.02.03, 10.02.04 and 10.02.05, a soil erosion and Supp.No.17 LDC6:5 COLLIER COUNTY LAND DEVELOPMENT CODE 6.01.05 A. 6.02.01 C. sediment control plan shall be prepared and submitted for approval with the required construction documents for each proposed project as prescribed by objective 5.4 and policy 5.4.1 of the Conserva- tion and Coastal Management Element of the Collier County Growth Management Plan. 1. Application.The Administrative Code shall establish the procedure and submittal requirements for a Soil Erosion and Sediment Control Plan. B. Developments not requiring a Soil Erosion and Sediment Control Plan shall implement and maintain best management practices in accordance with the Florida Stormwater Erosion and Sedimentation Control Manual for sediment and soil erosion control,to prevent the transport of sediment and pollutants off site. 1. All sediment and soil erosion control devices shall be installed prior to the commencement of construction for demolition, renovation,alteration,construction,stockpiling of fill,lot clearing or grading. 2. During construction activities, the applicant shall remove any pollutant, silt, debris, or dirt resulting from the construction activities that accumulates off site or within any stormwater management system,including but not limited to swales, lakes,ponds,canals,and waterways. 3. Debris generated on site, including but not limited to building materials, concrete truck wash-out, litter, and sanitary waste shall be stored, secured, or otherwise controlled on site. (Ord. No. 13-56, § 3.Y;Ord. No. 18-18, §3.M) 6.02.00 ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.02.01 Generally A. This section is intended to implement and be consistent with the GMP,§ 163.3161 et seq., F.S.,and the Florida Administrative Code, by ensuring that all development in the County is served by adequate public facilities.This objective is accomplished by the following: 1. Establishing a management and monitoring system to evaluate and coordinate the timing and provision of the necessary public facilities to serve development. 2. Establishing a regulatory program that ensures that each public facility is available to serve development concurrent with the impacts of development on the public facilities. 3. No approval of the final subdivision plat, improvement plans,or authorization to proceed with construction activities in compliance with the same shall require the County to issue a development order or building permit if it can be shown that issuance of said development order or building permit will result in a reduction in the level of service for any public facility below the level of service established in the GMP, or if issuance of said development order or building permit is inconsistent with the GMP. Anything in this section to the contrary notwithstanding, all subdivision and development shall comply with the Collier County requirements for adequate public facilities. B. Procedures for determinations of vested rights for adequate public facilities are set forth in Chapter 9. C. Procedures for applications for certificates of public facility adequacy are set forth in the Administrative Code and LDC section 10.02.07. Supp.No.17 LDC6:6 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.02.01 D. 6.02.01 D.3. D. For the purposes of this section only, the following terms are defined as follows: 1. Capital access means the planning of, engineering for, acquisition of land for,or the construc- tion of drainage and water management facilities necessary for proposed development to meet the (LOS) for access. 2. Capital drainage facilities: The planning of, engineering for, acquisition of land for, or the construction of drainage and water management facilities necessary for proposed develop- ment to meet the LOS for drainage facilities. 3. Capital road facilities or capital road improvement means and will include transportation planning for,engineering of, right-of-way acquisition for,and construction of any project eligible for inclusion as a road project in the road component of the(CIE)of the GMP or the Five-Year FDOT Work Program. Supp.No.17 LDC6:6.1 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.02.01 D.4. 6.02.01 D.13. 4. Capital potable water facilities mean the planning of, engineering for, acquisition of land for, or construction of potable water facilities necessary to meet the LOS for potable water facilities. 5. Capital sanitary sewer facilities mean the planning of, engineering for, acquisition of land for, or construction of sanitary sewer facilities necessary to meet the LOS for sanitary sewer facilities. 6. Capital solid waste facilities mean the planning of, engineering for, acquisition of land for, or construction of solid waste facilities necessary to meet the LOS for solid waste facilities. 7. Comprehensive plan means a plan that meets the requirement of§§ 163.3177 and 163.3178, F.S., and shall mean the GMP, where referenced in this section. 8. Constrained facilities are those road facilities which have been so designated by action of the BCC upon the recommendation of the County Manager or designee once it has been determined that the road facility will not be expanded by two or more through lanes due to physical, environmental, or policy constraints. 9. Physical constraints exist when intensive land use development is immediately adjacent to existing through lanes making road facility expansion cost prohibitive, or when a road facility has reached the maximum through lane standards acceptable the to the county. For county maintained facilities, the maximum through lane standard for a road facility will be no greater than six through lanes with allowances for auxiliary or service lanes as deemed operationally necessary. For state maintained facilities, the maximum through lane standard will be as designated by the FDOT. 10. Environmental and policy constraints exist when decisions are made not to expand a road facility based on environmental, historical, archeological, aesthetic or social impact consid- erations. Policy constraints are artificial barriers to road facility expansions based on environmental or political realities within a community. Unlike physical constraints, however, these barriers to road facility expansion can change over time,as needs and community goals change. 11. Deficient road segment means a county or state road segment on the major road network system that is operating below its adopted(LOS)standard as determined by roadway service volumes calculated by the County Manager or designee. 12. Transportation Concurrency Management System means a "real time" concurrency system that tracks and allocates the available roadway capacity on a continuous basis with quarterly status reports to the Board. Trips generated from proposed developments will be added to the trips approved to date and the existing background traffic counts to determine if there is available capacity for each new development to be approved, in whole or part, as proposed development plans are submitted.Application of this system is limited to the following final local development orders: site development plan, site development plan amendment, site improvement plan, and subdivision plat and plan application. 13. Proportionate share payment means a payment by a developer to Collier County to be used to enhance roadway operations, mass transit operations or other non-automotive transpor- tation alternatives. (Ord. No. 08-08, § 3.L; Ord. No. 12-38, § 3.X; Ord. No. 13-56, § 3.Z) Supp. No. 11 LDC6:7 COLLIER COUNTY LAND DEVELOPMENT CODE 6.02.02 6.02.02 C. 6.02.02 Management and Monitoring Program A. Generally. In order to implement the mandate of the GMP to ensure that adequate potable water, sanitary sewer, solid waste, drainage, park, and road public facilities are available to accommodate development in the County concurrent with the impacts of development on such public facilities,the BCC establishes, pursuant to the terms of this section: (1) a management and monitoring program that evaluates the conditions of public facilities to ensure they are being adequately planned for and funded to maintain the LOS for each public facility,and(2)a regulatory program that ensures that each public facility is available to serve development orders which are subject to the provisions of this section. 1. If the County Manager or designee determines that a site development plan or plat application when reviewed cumulatively with projects submitted within the last 6 months from the same master project or development does not meet the transportation concurrency requirements or is contrary to the purpose and intent of this section,as stated above, he may withhold approval of said development order application until adequate capacity is available or require the application submittals to be reviewed cumulatively and subsequent impacts to be distributed and accounted for within the same impact boundary of the master project or development. B. Annual update and inventory report on public facilities. The County Manager or designee shall complete an annual update and inventory report on public facilities(AUIR).The AUIR shall include an analysis of the existing conditions of all capital potable water, capital sanitary sewer, capital solid waste, capital drainage, capital park, and capital road public facilities; summarize the available capacity of these capital improvements (public facilities) based on their LOS;forecast the capacity of existing and planned public facilities identified in the 5 year capital improvement schedule for each of the 5 succeeding years, and 10 succeeding years for solid waste landfill capacity; and identify new projects needed to maintain or restore adopted LOS. The forecasts shall be based on the most recently updated schedule of capital improvements and Capital Improvements Plan (CIP) or Master Plan for each public facility.The AUIR shall be based on the most recent University of Florida bureau of economic and business research (BEBR), or BEBR influenced Water and Sewer Master Plan, population projections, updated public facility inventories, updated unit costs and revenue projections, and analysis of the most recent County traffic data. The findings of the AUIR shall form the basis for the preparation of the next annual update and amendment to the CIE, the determination of any area of significant influence (ASI), and the review and issuance of development orders subject to the provisions of this section during the next year. C. Annual determination of adequate"Category A" public facilities(concurrency).The County Manager or designee will annually present the AUIR to the BCC, identifying deficiencies or potential deficiencies in potable water, sewer, sold waste, drainage, parks, and roads public facilities and remedial action options including, but not limited to, the following: 1. Establishment of an ASI; 2. Public facility project additions to the financially feasible CIE; 3. Establish interim development controls in affected service areas pending: a. Lowering of LOS via GMP amendment; Supp. No. 11 LDC6:8 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.02.02 C. 6.02.02 H. b. Inclusion of necessary public facility projects in the next adopted annual budget and next annual CIE update and amendment; c. Approval of new or increased revenue sources for needed public facility projects by the BCC, the state legislature, or the County voters; or d. Private development improvements guaranteed by an enforceable devel- opment agreement. D. The findings of the AUIR,once approved by the BCC,will form the basis for the preparation of the next annual update and amendment of the CIE and the annual determination of deficient or constrained "Category A" facilities. The AUIR will identify additional projects and funding for inclusion in the Schedule of Capital Improvements and the Costs and Revenues Schedule of the CIE needed to maintain or restore adopted LOS for all "Category A" facilities for the next 5 years. The BCC shall provide direction to update and amend the CIE to include projects and revenues (within the first or second years for roads) needed to maintain or restore adopted LOS. Said direction shall constitute a finding of concurrent "Category A" facilities, except roads, for the review and issuance of develop- ment orders subject to the provisions of this section until the presentation of the next AUIR, except for any ASI designated areas or other areas subject to interim development controls. In addition to identifying needed capacity expansion projects and revenues for inclusion in the next CIE update, the road facilities component of the AUIR will include an audit and update of the capacity balances in the Transportation concurrency Management System database. The update shall factor in all such development approvals since the previous AUIR that generate trips along each road segment and the effect of capacity expansion projects included in the financially feasible Schedule of Capital Improvements of the CIE The AUIR shall be the annual baseline of an ongoing, real-time concurrency determination for roads. E. Recommendations on the annual CIE update and annual budget. Based upon the prior calendar year's AUIR analysis and BCC direction, the County Manger or designee shall recommend to the Planning Commission and the BCC an annual update and amendment to the CIE as part of the annual GMP amendment cycle. The recommendation will include the proposed financially feasible public facilities Schedule of Capital Improvements needed to maintain or restore adopted LOS standards as well as recommendations for the annual budget, projects, and suggested funding sources. F. Designation of deficient and constrained roadway segments. Deficient roadway segments may be designated as constrained whenever they meet the terms set forth in subsections 6.02.01 D.7. of the LDC. G. Regulation of growth along roadway segments designated constrained. Roadway segments once designated as constrained are subject to the growth restrictions set forth below which are intended to ensure that further LOS degradation does not occur. Except as provided for below in Transportation concurrency Exemption Areas(TCEA)and Transportation concurrency Management Areas(TCMA), deficient constrained roadway segments are subject to growth restrictions on development that will not allow for approval of a final local development order resulting in an increase in peak hour traffic volume above the adopted LOS standard. H. Regulation of growth along deficient roadway segment(s). Except as provided for below in Transpor- tation concurrency Exemption Areas (TCEA) and Transportation concurrency Management Areas (TCMA),no trips shall be allotted under a Certificate of Public Facility Adequacy for development that directly accesses and generates more than a de minimis impact (de minimis impact is defined as Supp. No. 11 LDC6:9 COLLIER COUNTY LAND DEVELOPMENT CODE 6.02.02 H. 6.02.02 1.3. traffic impact of 1 percent or less of the peak hour service volume) on the deficient roadway segment(s) or for which the significance test in (N) below indicates that the development will generate more than a de minimis impact on the deficient roadway segment(s). Transportation Concurrency Exemption Area Designated. Pursuant to Policy 5.5 of the Future Land Use Element of the GMP, the South U.S. 41 Transportation concurrency Exception Area (TCEA) is designated. development located within the South U.S. 41 TCEA(Map TR-4) shall be exempt from transportation concurrency requirements, so long as impacts to the transportation system are mitigated using the procedures below. 1. Any proposed development within the concurrency exception area that would reduce the LOS on Florida Intrastate Highway System (FINS) roadways within the County by more than 5%of the capacity at the adopted LOS standard must meet the transportation concurrency requirements specified in Rule 9J-5.0055(3)(c)1-7, F.A.C. 2. Any proposed development within the concurrency exception area that would reduce the LOS on FIRS roadways within the County by less than 5%of the capacity at the adopted LOS standard and meets the requirements identified below in (3) below are exempt from the transportation requirements of 9J-5.0055(3)(c)1-7, F.A.C. 3. Commercial developments within the South U.S. 41 TCEA that choose to obtain an exception from concurrency requirements for transportation will provide certification from the Transportation Division that at least 4 of the following Transportation Demand Management (TDM) strategies will be utilized: a. Preferential parking for carpools and vanpools that is expected to increase the average vehicle occupancy for work trips generated by the development. b. Parking charge that is expected to increase the average vehicle occupancy for work trips generated by the development and/or increase transit ridership. c. Cash subsidy that is expected to increase the average vehicle occupancy for work trips generated by the development and/or increase transit ridership. d. Flexible work schedules that are expected to reduce peak hour automobile work trips generated by the development. e. Compressed work week that would be expected to reduce vehicle miles of travel and peak hour work trips generated by the development. f. Telecommuting that would reduce the vehicle miles of travel and peak hour work trips generated by the development. g. Transit subsidy that would reduce auto trips generated by the development and increase transit ridership. h. Bicycle and pedestrian facilities or that would be expected to reduce vehicle miles of travel and automobile work trips generated by the development. i. Including residential units as a portion of a commercial project that would reduce vehicle miles of travel. Supp. No. 11 LDC6:10 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.02.02 1.4. 6.02.02 K. 4. Residential developments within the South U.S.41 TCEA that choose to obtain an exception from concurrency requirements for transportation shall obtain certification that at least 3 of the following Transportation Demand Management (TDM) strategies will be utilized: a. Including neighborhood commercial uses within a residential project. b. Providing transit shelters within the development (must be coordinated with Collier County Transit). c. Providing bicycle and pedestrian facilities, with connections to adjacent commercial properties. d. Including affordable housing (minimum of 25% of the units) within the develop- ment. e. Vehicular access to adjacent commercial properties with shared commercial and residential parking. Developments within the South U.S. 41 TCEA that do not provide certification shall meet all concurrency requirements. Whether or not a concurrency exception is requested, devel- opment applicants must submit a Traffic Impact Statement and are subject to a concur- rency review for the purpose of reserving capacity for those trips associated with the development and maintaining accurate accounts of the remaining capacity on the roadway network. concurrency analysis will be conducted utilizing the significance tests contained in section 6.02.02 N. below. An applicant seeking an exception from concurrency requirements for transportation through the certification mentioned above shall submit an application to the Transportation Division Administrator on forms provided by the Division. Binding commitments to utilize any of the above techniques relied upon to obtain certification shall be required as a condition of development approval. J. Transportation Concurrency Management Areas Designated. Pursuant to Transportation element Policy 5.7 of the GMP,the following Transportation concurrency Management Areas are designated: 1. Northwest TCMA-This area is bounded by the Collier - Lee County Line on the north side; the west side of the 1-75 right-of-way on the east side; Pine Ridge Road on the south side; and, the Gulf of Mexico on the west side (Map TR-5). 2. East Central TCMA - This area is bounded by Pine Ridge Road on the north side; Collier Boulevard on the east side; Davis Boulevard on the south side; and, Livingston Road (extended)on the west side(Map TR-6)with the exception of 1-75 which is not included in the concurrency analysis. K. Concurrency Standard for TCMA. To maintain concurrency, each TCMA shall maintain 85% of its north-south lane miles and 85%of its east-west lane miles at or above the LOS standards described in Policies 1.3 and 1.4 of the GMP Transportation element. If any Traffic Impact Statement (TIS) for a proposed development indicates that fewer than 85% of the lane miles in a TCMA are achieving the LOS standards indicated above, the proposed development shall not be permitted where such condition occurs unless modification of the development is made sufficient to maintain the LOS Supp. No. 11 LDC6:11 COLLIER COUNTY LAND DEVELOPMENT CODE 6.02.02 K. 6.02.02 L.S. standard for the TCMA, or the facilities required to maintain the TCMA LOS standard are committed utilizing the standards for committed improvements in Policy 1.5.3 of the Capital Improvement Element of the GMP. L. Proportionate share payments for impacts to constrained or deficient roadways in a TCMA.Should the TIS for a proposed development reflect that it will impact either a constrained roadway link and/or a deficient roadway link by more than a de minimis amount (more than 1% of the maximum service volume at the adopted LOS), yet continue to maintain the established percentage of lanes miles indicated in paragraph (L) above, a proportionate share payment pursuant to Rule 9J-5.0055(9), F.A.C. shall be required as follows: 1. Proportionate share payments shall be calculated using the formula established in section 10.02.07 C.4.g. The facility cost for a constrained roadway link shall be established using a typical "lane mile cost" as determined by the Collier County Transportation Administrator of adding lanes to a similar area/facility type as the constrained facility. 2. Proportionate share payments shall be utilized by Collier County to add trip capacity and enhance traffic operations that increase capacity within the impacted TCMA and/or to enhance mass transit or other non-automotive transportation alternatives that reduce vehicle trips within the Transportation Concurrency Management Area. 3. However, no impact will be de minimis if it exceeds the adopted level-of-service standard of any affected designated hurricane evacuation routes within a TCMA. Hurricane routes in Collier County are shown on Map TR7. Any impact to a hurricane evacuation route within a TCMA shall require a proportionate share payment provided the remaining LOS requirements of the TCMA are maintained. 4. Proportionate share payments under this section are determined subsequent to a concur- rency determination for a proposed development within a TCMA and do not influence the concurrency determination process. 5. In order to be exempt from link specific concurrency, new commercial development or redevelopment within Collier County's designated Transportation concurrency Management Areas (TCMAs) shall utilize at least 2 of the following Transportation Demand Management (TDM) strategies, as may be applicable: a. Preferential parking for carpools and vanpools that is expected to increase the average vehicle occupancy for work trips generated by the development. b. Parking charge that is expected to increase the average vehicle occupancy for work trips generated by the development and/or increase transit ridership. c. Cash subsidy that is expected to increase the average vehicle occupancy for work trips generated by the development and/or increase transit ridership. d. Flexible work schedules that are expected to reduce peak hour automobile work trips generated by the development. e. Compressed workweek that would be expected to reduce vehicle miles of travel and peak hour work trips generated by the development. Supp. No. 11 LDC6:12 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.02.02 L.S. 6.02.02 M.1. f. Telecommuting that would reduce the vehicle miles of travel and peak hour work trips generated by the development. g. Transit subsidy that would reduce auto trips generated by the development and increase transit ridership. h. Bicycle and pedestrian facilities that would be expected to reduce vehicle miles of travel and automobile work trips generated by the development. i. Including residential units as a portion of a commercial project that would reduce vehicle miles of travel. j. Providing transit shelters within the development (must be coordinated with Collier County Transit). In order to be exempt from link specific concurrency, new residential development or redevelopment within Collier County's designated Transportation concurrency Management Areas (TCMAs) shall utilize at least 2 of the following Transportation Demand Management (TDM) strategies, as may be applicable: a. Including neighborhood commercials uses within a residential project. b. Providing transit shelters within the development(must be coordinated with Collier County Transit). c. Providing bicycle and pedestrian facilities, with connections to adjacent commercial properties. d. Including affordable housing (minimum of 25% of the units) within the development. e. Vehicular access to adjacent commercial properties. M. A significance test shall be performed in compliance with the Traffic Impact Study(TIS)Guidelines and Procedures. This significance test is applicable to projects inside and outside Traffic Concurrency Exception Areas (TCEAs) and Traffic Concurrency Management Areas (TCMAs) as adopted in the Growth Management Plan. 1. Impact for traffic impact analysis purposes for a proposed development project will be considered significant when: a. On those roadway segments directly accessed by the project where project traffic is equal to or greater than 2 percent of the adopted LOS standard service volume; b. On those roadway segments immediately adjacent to segments which are directly accessed by the project where project traffic is greater than or equal to 2 percent of the adopted LOS standard service volume; or c. On all other adjacent segments where the project traffic is greater than 3 percent of the adopted LOS standard service volume. Supp. No. 11 LDC6:13 COLLIER COUNTY LAND DEVELOPMENT CODE 6.02.02 M.2. 6.02.03 B. 2. Once traffic from a development has been shown to be less than significant on any segment '�- using the above standards, the development's impact is not required to be analyzed further on any additional segments. However, site impact analysis shall be conducted in accordance with the TIS Guidelines and Procedures. N. Establishment of an ASI for deficient road segments. If the findings of the AUIR analysis identify additional road improvement projects that would be needed in order to maintain a segment or road facility's adopted LOS, and such projects are not included in the proposed annual CIE road component update adopted by the BCC, then the County Manager or designee, may propose to establish one or more ASI for any such deficient road segment. O. Standards in establishing an ASI. The boundaries for an ASI shall include the limits of the roadway segment(s) that are deficient as recommended by the County Manager or designee. 1. After receipt of the proposed boundaries of a potential ASI,the BCC shall hold public hearings noticed pursuant to the requirements of Chapter 10 of the LDC.After final consideration of the proposal and public comment, the BCC may approve the designation of an ASI (including a map of the impacted roadway segments), with or without modifications, or determine that competent substantial evidence has been introduced into the record to show that the road segment is not deficient and find that the establishment of an ASI is not necessary to ensure that development orders are served by adequate road public facilities.The approved ASI(s) will become effective upon adoption by the BCC. 2. A map showing the deficient roadway segments(s) within each ASI established by the BCC shall be kept in the community development and environmental services division and the office of the clerk to the BCC for review and inspection by the public during normal business hours. 3. Once the boundaries of an ASI are approved by the BCC, they are valid for 1 year, unless dissolved by the BCC or modified in a subsequent AUIR update. 4. No final local development order for development directly accessing deficient roadway segments may be approved if it would add more than a de minimis number of vehicle trips (i.e.,an impact greater than 1 percent of the peak hour service volume)to a deficient roadway segment designated as an ASI. Development of a single-family home on an existing lot, tract, or parcel of land will be considered to be de minimis development regardless of the number of actual trips that would be generated. (Ord. No. 06-63, § 3.11; Ord. No. 08-63, § 3.X) 6.02.03 Transportation Level of Service Requirements A. All developments that impact the traffic network shall be evaluated in accordance with the Traffic Impact Study (TIS) Guidelines and Procedures. B. The analysis shall show the impact on the proposed internal streets of the subdivision or development and existing externally affected streets. The analysis shall be used to determine the street classification, width and number of traffic lanes internal to the development, and any requirements for off-site (external) improvements on the existing street system per the GMP.

Level of service calculations for road facilities means calculations for peak hour traffic on a roadway segment for maximum service volumes at the adopted LOS. Peak hour is calculated as the 100th highest hour based on a 10 month period(omitting February and March),which is generally equivalent to the 250th highest hour for a twelve(12)month period. For design of roadway capacity projects,the 30th highest hour for a 12-month period at LOS "D" will be utilized. D. In assessing the capacity of a County road segment, a state road segment or TCMA for the purpose of determining whether it is operating below the adopted LOS, or would based on the traffic impacts identified in an approved TIS submitted as part of an application for a final local developments order, the County shall consider: 1. Current roadway facilities including, but not limited to, number of lanes, provision of turn lanes, operation of intersections, and number of signals. 2. Capital road improvements under construction, or for which the construction contract has been let. 3. Any improvements that are guaranteed in an enforceable development agreement in which the improvements are completed or under construction, or for which the construction contract has been let, before the impacts from the development or phased development accrue to the roadway system. 4. Construction of the required capital improvement is included in the first or second year of either the Florida DOT 5 year work program or the first or second year of the Collier County Schedule of Capital Improvements adopted as part of the Annual Update and Amendment of the Capital Improvements Element (CIE) and Collier County Annual Budget that follows approval of the AUIR. 5. The BCC has made an express finding, after a public hearing, that the current 5-year capital improvement schedule is based on a realistic, financially feasible program of funding from existing revenue sources. 6. The final local development order is for a project located within a TCEA or TCMA designated in the GMP which meet the applicable requirements of Policies 5.5 through 5.9 of the Transportation Element. 7. The necessary facilities are the subject of a binding commitment with the developer to contribute fair share funding as provided for in Policy 5.9 of the Transportation Element, if applicable, or to construct the needed facilities. E. The LOS for capital road facilities on the major road network system are as set forth in Policy 1.1.5 of the CIE and Policy 1.4 of the Transportation Element of the GMP. F. Proportionate Share Payments. Proportionate share payments may be used to mitigate the impacts of a development on a deficient roadway link by more than a de minimis amount within a Transportation Concurrency Management Area in which 85 percent of the north-south lane miles and 85 percent of the east-west lane miles are operating at or above the adopted LOS standards consistent with Policies 5.8 and 5.9 of the Comprehensive Plan Transportation Element. 1. However, no impact will be de minimis if it exceeds the adopted level-of-service standard of any affected designated hurricane evacuation routes within a TCMA. Hurricane routes in Supp. No. 11 LDC6:15 COLLIER COUNTY LAND DEVELOPMENT CODE 6.02.03 F.1. 6.02.04 A.2. Collier County are shown on Map TR7 of the Transportation Element. Any impact to a hurricane evacuation route operating below the adopted LOS within a TCMA shall require a proportionate share payment provided the remaining LOS requirements of the TCMA are maintained. Proportionate share payments under this section are determined subsequent to a finding of concurrency for a proposed project within a TCMA and do not influence the concurrency determination process. Development of an individual single-family residence will not be required to contribute or make a proportionate share payment under this section. a. The proportionate share of the cost of improvements of such deficient roadways is calculated according to the following formula: Project trips impacting deficient link/SV increase x cost = proportionate share. Project trips = Cumulative number of the trips from the proposed develop- ment expected to reach the roadway during the peak hour from the complete buildout of a stage or phase being approved. ii. SV increase = The change in peak hour maximum service volume of the roadway resulting from construction of the improvement necessary to maintain the adopted level of service. iii. Cost = Cost of construction, at the time of developer payment, of an improvement necessary to maintain the adopted level of service. Construc- tion cost includes all improvement associated costs, including engineering design, right-of-way acquisition, planning, engineering, inspection, and other associated physical development costs directly required and associ- ated with the construction of the improvement. b. The cost for a deficient roadway link shall be established using a typical "lane mile cost" of adding lanes to a roadway having a similar area type/facility type as determined by the Collier County Transportation Administrator.

M. Street drainage.Street drainage within the road right-of-way through grassed swales will be permitted for rural cross sections only except where velocities in excess of four feet per second are anticipated. The flow from these swales or other types of drainage facilities will be diverted to natural percolation areas,artificial seepage basins or artificial lakes of at least sufficient capacity to comply with the criteria Supp.No.16 LDC6:22 INFRASTURCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.05.01 M. 6.05.01 O. of Collier County and the South Florida Water Management District.Other equally effective methods of returning cleansed waters to the aquifer will be acceptable upon prior review and approval by the County Manager or designee. 1. Existing natural lakes may be used as detention areas provided that they have adequate storage capacity and that pretreatment measures approved by the County Manager or designee are taken to prevent pollutant matter from entering the lake.Positive outfall drainage facilities will be provided away from all percolation areas,seepage basins,detention areas and artificial lakes to handle the runoff from storms which exceed the required design storm event in duration and/or severity. N. Percolation areas.The actual area required will depend on the percolation rate for the soils at the specific site and the manner in which the site is developed in accordance with Collier County and South Florida Water Management District criteria. 1. Underground drainage.Where drainage plans provide for, or it is so directed by the County Manager or designee, the collection of stormwater in underground pipes, inlets and other appurtenances for conveyance to an intermediate or ultimate outfall, the following minimum design criteria will be observed: a. The minimum pipe used within a publicly maintained stormwater collection system will be 15 inches in diameter. b. Inlets will be spaced at such intervals and in such a manner to allow for the acceptance of 100 percent of the ten-year, one-hour storm runoff. c. The distance between terminating and intermediate structures must not exceed those required by the Florida Department of Transportation,pursuant to Florida Department of Transportation Drainage Manual,Volumes 1-4 (1987 edition or latest revision). d. The stormwater, underground collection system, must be so designed that the eleva- tion of the hydraulic gradient during a ten-year, one-hour storm event is never higher than the crown elevation of any publicly maintained roadway in the system. e. The pipes must be designed to minimize sediment deposits. f. The pipe materials must meet the requirements set forth in sections 943-948 inclusive of the current edition of the Florida Department of Transportation Standard Specifications for Road and Bridge Construction. Only concrete pipe or other pipe materials approved by the County Manager or designee may be used in tidal or salt waters. g. All drainage pipes must be fitted with headwalls,endwalls,inlets and other appropriate terminating and intermediate structures. O. Stormwater disposal.The method of ultimate disposal of stormwaters will be dependent upon the soil characteristic underlying the development or subdivision. All stormwaters will be subjected to treatment for the removal of petroleum residues, oils, suspended solids and other pollutants found in stormwater runoff. The method of treatment will be determined by the applicant's professional Supp.No.16 LDC6:23 COLLIER COUNTY LAND DEVELOPMENT CODE 6.05.01 O. 6.05.03 8.2. engineer responsible for the preparation of the stormwater management plans and specifications, and will be subject to the approval of the County Manager or designee and the concerned state agencies.

At the entry/exit of any residential or commercial development approved through a SDP,SDPA,or PPL located on a public collector or arterial street, the following additional standards shall apply. For projects subject to architectural design standards, see LDC section 5.05.08 F.for related provisions. 1. At the points where the edges of pavement of the entrance road meet the intersecting right-of-way line, the illumination level shall be at or between, a minimum of 2.0 foot candles and maximum of 5.0 foot candles.In cases when this Code may conflict with any other lighting codes, requirements, policies, or recommendations relating to the spillover of light outside of project boundaries, public safety needs shall be evaluated by staff and shall take precedence in the required placement of fixtures. 2. A full cutoff fixture is required on both sides of each entry or exit outside of the intersecting public right-of-way except when located at a single-lane one-way driveway.In such case,one (1)fixture will be allowed but it shall meet minimum required foot-candle values.If the applicant can show the existing illumination levels from existing roadway lighting meet the required foot candles through a photometric lighting plan(calculated or by field measurement)certified by an engineer,licensed in the State of Florida,the county manager or designee may waive or modify the requirement for additional lighting at the point where the entry road intersects the public right-of-way. C. All sidewalks not directly lighted by street lighting that interconnect developments must be lighted to pedestrian level standards per IESNA RP-8-00. D. Wherever, in the opinion of the County Manager or designee,based on an engineer's determination, a dangerous condition is created by sharp curves, irregularities in street alignment, or other similar circumstances, additional lights may be required. Streetlights and mounting poles shall be wired for underground service.All conduits and casing to be placed under the roadway required for the lights must be installed during each construction phase prior to roadway subbase completion. Streetlights shall be designed and installed in either of 2 ways: 1. Where streetlights are to be installed on private streets, the developer, through an electrical engineer registered in the State of Florida, shall design and install the street lighting system subject to the approval of the County Manager or designee.Upon completion of the streetlights, they shall be owned, operated, and maintained by the property owners' association, a condominium association,cooperative association, or other similar entity,or the public utility furnishing the electric service. 2. Where the streetlights are to be installed on public streets,the developer may elect to initiate a municipal services benefit or taxing unit in coordination with the County Manager or designee in order to provide street lighting.If the municipal services benefit or taxing unit is approved by the BCC, the County Manager or designee shall authorize the public utility to design, install, Supp.No.15 LDC6:37 COLLIER COUNTY LAND DEVELOPMENT CODE 6.06.03 D.2. 6.06.05 E. and maintain the street lighting system at no cost to the County's general fund.If no municipal services benefit or taxing unit is created for public streets, the provision of this section shall govern the design, construction, and maintenance of streetlights.

Bridges shall be designed in accordance with current Florida Department of Transportation practices or appropriate specifications by the applicant's structural engineer and may be required to include provisions for utility installations and will require sidewalks on both sides of the bridge.The bridge shall be designed by a Florida professional engineer and is subject to the approval of the County Manager or designee and those other agencies having jurisdiction over the proposed facilities.Generally, bridges shall be designed as reinforced concrete,however,other low maintenance materials may be used upon request and approval, when supported by a design report prepared by the applicant's professional engineer which provides particular assurance relative to the integrity of the materials to be utilized. B. At a minimum,the width of all bridges shall be required to incorporate a clear roadway width equaling the travel lane width plus 2 feet to the curb and 6 foot sidewalks;however,variations may be considered pursuant to Chapter 10. Bridge width shall vary with the classification of the roadway section to be carried.All bridge structures shall be designed for H-20 loading,incorporating adequate corrosion and erosion protection. 6.06.05 Clear Sight Distance A. Where an accessway intersects a right-of-way or when a property abuts the intersection of 2 or more rights-of-way. a minimum safe sight distance triangular area shall be established. Any vegetation within this area shall be planted and maintained in a way that provides unobstructed visibility at a level between 30 inches and 8 feet above the crown of the adjacent roadway.Landscaping shall be located in accordance with the roadside recovery area provisions of the State of Florida Department of Transportation's Manual of Uniform Minimum Standards for Design,Construction,and Maintenance of streets and Highways (DOT Green Book) where appropriate. Posts for illuminating fixtures, traffic control, and street name signs shall also be permitted, so long as the sign or equipment is not within the prescribed clear space. B. Where an accessway enters a right-of-way, 2 safe distance triangles shall be created diagonally across from each other on both sides of the accessway.Two sides of the triangle shall extend 10 feet each way from the point of intersection from the edge of pavement and the right-of-way line.The third side of the triangle shall be a line connecting the ends of the other 2 sides. C. Where a property abuts the intersection of 2 rights-of-way, a safe distance triangle shall be created. Two sides of the triangle shall extend 30 feet along the abutting right-of-way lines,measured from the point of intersection.The third side of the triangle shall be a line connecting the ends of the other 2 sides. D. The developer shall comply with all of the provisions of the applicable landscape requirements and section 4.06.00 at the time of subdivision or development approval or when applicable. E. On a corner lot in all zoning districts, no fence, wall, hedge, planting, or structure shall be erected, planted, or allowed to grow in such a manner as to obstruct vision between a height of 30 inches and 8 feet above the centerline grades of the intersecting streets in the area bounded by the right-of-way lines of such corner lots and a line joining points along said right-of-way lines 30 feet from the point of Supp.No.15 LDC6:38 INFRASTRUCTURE IMPROVEMENTS AND ADEQUATE PUBLIC FACILITIES REQUIREMENTS 6.06.05 E. 6.06.05 E. intersection.Parking is prohibited in this area.Trees are permitted,so long as the foliage is cut away and maintained within the 30 inch and 8 foot clearance requirement.
