Section 2.1. Overall goals for Martin County's Comprehensive Growth Management Plan.

Martin County has endeavored to establish a Comprehensive Growth Management Plan which broadens, enhances, and protects the quality of life for its residents. The overall goals for the Comprehensive Growth Management Plan are keyed to maintaining quality residential and nonresidential uses, natural resource conservation and preservation of beneficial and protective natural systems, enhanced economic development, and fiscal conservancy.

Martin County has been proclaimed a 'Sustainable County' by the state land planning agency. Sustainable means meeting the needs of the present without compromising the ability of future generations to meet their needs.  All planning decisions made by the County shall be based upon a consideration of impacts on the ecology, quality of life and fiscal sustainability of such actions, including the long term cumulative impacts.

Section 2. 2. – Goals, Objectives and Policies

Goal 2.1. Martin County shall broaden, enhance, and protect the quality of life of Martin County residents.

Objective 2.1A. Text amendments to the CGMP and amendments to the FLUM shall allocate land use so as to provide for compatibility with existing development and long term planning goals.

Policy 2.1A.1: No land uses or development shall:

(1)   exceed 15 units per acre.

(2)   have more than four stories including those unenclosed lower floors used for storage, parking or other purposes. Rebuilding of oceanfront structures on Hutchinson Island to the original building configuration shall not be considered inconsistent with this policy.

(3)   be more than 40 feet high. Building height shall be measured from the average finished grade at the perimeter of the building, except in flood hazard areas. In flood hazard areas building height shall be measured from the base flood elevation requirement for the lowest floor as shown on the flood insurance rate map published by the Federal Emergency Management Agency (FEMA). Building height shall be the difference between the finished grade or the base flood elevation described above and  either the highest point of the coping of a flat roof, the deck line of a mansard roof, or the mean height level between eaves and ridge of gable, hip, and gambrel roofs. The mean height level between the ridge and the eaves shall be determined on the highest section of roof. Limited exceptions shall be allowed for structures such as church steeples, roof structures, utility poles, park lighting, emergency structures, agricultural and industrial structures, and communications facilities as detailed in Article 3, Section 3.14., Land Development Regulations, Martin County Code on August 13, 2013.

Policy:2.1A.2. Existing and future residential areas shall be protected from encroachment by commercial or industrial development or other non-residential uses and by more intensive residential uses, which would be incompatible with such residential uses. All plan amendments and development approvals shall protect residential neighborhoods from the negative impacts of more intense development. This is not intended to preclude necessary community facilities within the residential areas where residents are protected from negative impacts.

Policy:2.1A.3. In areas of residential development, project design shall ensure that comparable density and dwelling unit types are planned for the area of the project abutting existing residential development. For purposes of this policy, abutting property is the same as “adjacent,” “immediately adjacent” or “adjoining” property and shall refer to property with a shared property line or to properties separated only by right of ways or easements. Properties separated by an existing road with a minimum 30 foot right of way shall not be considered abutting.

(1) Projects directly adjacent to lands used or designated for higher density may be

given maximum density.

(2)   Projects immediately adjacent to lands used or designated for lower density use should be given less than maximum density and shall provide for reduced density next to the existing lower density residential area.

(3) Within the urban service districts where lot sizes in the existing residential development are two acres or less and density is more than 1 unit per 2 acres, the following shall apply: For projects abutting a residential development of lesser density, a density transition zone of comparable density and compatible dwelling unit types, shall be established in the new project for a depth from the shared property line that is equivalent to the depth of the first tier of the adjoining development’s lower density. (Ex. - the depth of the first block of single family lots.)

(4) Where the tiering Policy 4.1F.2.(1) and (2) applies, there shall be no requirement to construct residential units within the applicable area of the proposed development. However, if the area is left vacant, no other construction shall be allowed except for underground utilities, sidewalks, swales, stormwater ponds, and dry retention areas.

(5) A mixed use development containing residential units within a Mixed Use Overlay shall not be required to have a residential structure on that part of the project abutting existing development or area of lesser density within the Mixed Use Overlay. Buffers shall be as provided in Policy 4.3A.7.

Policy:2.1A.4. The Growth Management Department shall coordinate with the Building Department and the Property Appraiser's Office to provide an ongoing accurate inventory of land use. Good planning must be based on accurate information that is readily available.

Measure: The Growth Management Department shall provide an annual report on changes in the FLUM and on text changes that amended allowable land uses or development intensities or densities. The report shall include a summary of all development that has occurred in the preceding year in terms of acreage, residential units, non-residential upland acreage and land use designation. This information shall be used to update available acreage in each FLUM category and maximum allowable use on vacant residential acreage.

Objective 2.1B. Martin County shall create and maintain objective measures of quality of life for Martin Country residents.

Policy:2.1B.1. The Growth Management Department shall use Florida Abstracts to annually update Martin County data on school achievement, violent crime, poverty rate, and other indicators of quality of life.

Policy:2.1B.2. The Growth Management Department in conjunction with the Parks Department shall update data annually on the number of acres of active parks, miles of public beach, and acres of public open space.

Policy:2.1B.3. The Engineering Department shall report annually on sections of roadways that have deficient levels of service including an explanation of how these deficiencies will be addressed.

Policy:2.1B.4. The Engineering Department shall coordinate with the Sheriff’s Department to provide an annual analysis of traffic accidents and fatalities including proposals for improving roadways and intersections to avoid accidents.

Measure: At the time of the Evaluation and Appraisal Report (EAR) the county shall use the data collected under Policies 2.1B., 1., 2., 3., and 4. above to compare Martin County to adjacent counties and to counties of similar size in Florida.

Goal 2.2. Martin County shall ensure natural resource conservation and conservation of the area’s natural communities.

Objective 2.2A. Martin County shall preserve all wetlands regardless of size unless prohibited by state law.

Policy 2.2A.1. Wetlands are defined as areas that are inundated or saturated by surface water or groundwater at a frequency and a duration sufficient to support, and, under normal circumstances, do support, a prevalence of vegetation typically adapted for life in saturated soils.

All wetlands shall be preserved except is set out in the  exceptions listed below. “Wetlands” means those areas that are inundated or saturated by surface water or groundwater at a frequency and a duration sufficient to support, and under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils. Soils present in wetlands generally are classified as hydric or alluvial, or possess characteristics that are associated with reducing soil conditions. The prevalent vegetation in wetlands generally consists of facultative or obligate hydrophytic macrophytes that are typically adapted to areas having soil conditions described above. These species, due to morphological, physiological, or reproductive adaptations, have the ability to grow, reproduce, or persist in aquatic environments or anaerobic soil conditions. Florida wetlands generally include swamps, marshes, bayheads, bogs, cypress domes and strands, sloughs, wet prairies, riverine swamps and marshes, hydric seepage slopes, tidal marshes, mangrove swamps and other similar areas. Florida wetlands generally do not include longleaf or slash pine flatwoods with an understory dominated by saw palmetto. The delineation of the landward boundary of wetlands must be as required by state law.

The intent of this policy is to protect natural wetland systems even when they are affected by manmade excavations. This policy is not intended to protect manmade excavations in uplands.
Though manmade wetlands are exempt from this policy and are not protected as natural wetlands, development review shall assure that impacts to them do not adversely affect drainage or natural systems

Policy 2.2A.2. Exceptions to allow wetland alteration are limited to:

(a)(1) providing access for utilities, stormwater facilities, roads and bridges, removal of exotic vegetation, docks, boat entry, and elevated boardwalks

(b)(2) lots of record as of 1982 to provide reasonable use

(c)(3) CERP projects as outlined in Policy 9.1G.2.(7)(g).

Policy 2.2A.3. In all cases where wetlands alterations are allowed the least damaging alternative shall be chosen and mitigation shall replace the functions and values and the spatial extent of the altered wetlands. Exceptions shall not result in adverse impacts on plants and animals that are designated by the federal government or the state of Florida as “Endangered” or “Threatened”.

Policy:2.2A.4 Development plans shall provide water table restoration, buffers, exotic removal, long term maintenance guarantees, and any other actions necessary to assure the continuing values and functions of the wetland area.

Policy:2.2A.5. Where evidence indicates that drainage, clearing or other development or manmade impacts has taken place since April 1, 1982, in violation of applicable wetland development restrictions in effect at the time the violation occurred, restoration shall be required before any development permits or orders are issued, or within 90 days after receiving a notice of violation. A minimum two-year letter of credit or other acceptable financial alternative must be submitted to assure the successful restoration of the violation. This policy shall apply regardless of whether or not the wetlands in question have ever been delineated through either a binding or nonbinding boundary determination.

Policy:2.2A.6. The Growth Management Department, in coordination with Code Enforcement shall establish and maintain a procedure to effectively ensure compliance with Preserve Area Management Plans (PAMPS).

Measure: The Growth Management Department shall issue an annual report showing development approvals where wetlands have been, or are proposed to be, altered or destroyed, under the limited exceptions allowed in this Plan. Those exceptions apply only where complete preservation would deny reasonable use of the property. The report shall show the areal extent and location of wetlands to be created to ensure no net loss of the spatial extent of wetlands. Annual monitoring reports to assure viable restoration and compliance with PAMPs shall be included. The report shall include a list of wetlands violations and required restoration.

Objective 2.2B. Martin County shall preserve native upland habitat and threatened and endangered plant and animal species.

Policy:2.2B.1. Martin County shall assure that a minimum of 25% of existing upland native habitat will be preserved in all development where such habitat exists. Additional requirements for native upland habitat that is endangered or threatened, and for unique oak/cabbage palm hammocks are outlined in Chapter 9.

Policy 2.2B.2. Upland preservation areas and PAMPs approved by the county to protect them shall be designed and maintained to ensure sustainability.

Policy:2.2B.3. Martin County shall protect plants and animals and their habitat for species that are designated by the federal government and the State of Florida as “Endangered” or “Threatened.”

Objective 2.2C. Martin County shall ensure that all development orders, resolutions, and other official statements of County policy positions directed to other local, regional, state and federal agencies, as well as all other official actions of the County, support, further, and fight for a safe, healthy and ecologically balanced St. Lucie River Estuary and Indian River Lagoon, which are natural resources that are vital to the economy and quality of life of Martin County and the Treasure Coast.

Policy:2.2C.1. Martin County shall continue to work with the SFWMD, the state legislature, the Corps of Engineers and Congress to provide continuing implementation of Comprehensive Everglades Restoration Plan (CERP) and the Indian River Lagoon-South CERP component.

Policy:2.2C.2. Martin County shall lobby vigorously at the state and federal level for implementation of the CERP and the Indian River Lagoon South component.

Policy:2.2C.3. Martin County shall support the Corp’s Central Everglades Planning Project (CEPP) and other initiatives which will move more water south from Lake Okeechobee to Everglades National Park and provide storage and treatment in order to reduce fresh water, nutrient laden discharges into the St Lucie River from the C-23, C-24 and C-44 canals and Lake Okeechobee.

Policy:2.2C.4. Martin County shall encourage agency rule changes that move more water south within the current infrastructure limitations.

Policy:2.2C.5. Changes to the FLUM or the text of the Comprehensive Plan that would negatively affect implementation of CERP or the Indian River Lagoon South component by compromising their success or increasing cost, shall not be allowed unless the applicant clearly demonstrates with supporting evidence, that the denial of such request would result in a violation of its constitutional or statutory property rights.

Policy:2.2C.6. Development approvals shall ensure that, to the maximum extent practical, water quality and the rate, timing, and volume of runoff will recreate natural conditions for the benefit of wetlands, the estuary and other receiving waters.

Policy:2.2C.7. Martin County shall protect shorelines, mangroves, seagrasses, and oyster bars in the estuaries.

Policy:2.2C.8. Martin County shall work with residents to implement local programs to help lessen pollution in runoff from residential neighborhoods.

Policy 2.2C.9. All new development shall provide a 75 foot shoreline protection zone, extending landward from mean high water, within which there shall be no construction within or reductions to the shoreline protection zone, except as set forth below. This shall apply to the shoreline of the estuaries and to all of its navigable tributaries, including canals, recognizing the specific exceptions listed below. Where tributaries are blocked by weirs, dams, or locks the area upstream of these structures shall not be covered by the requirements of the shoreline protection zone.

The shoreline protection zone shall be defined as all estuarine waters within Martin County and all surface waters of the State that are both hydrologically connected to the estuarine waters and navigable. The shoreline protection zone shall extend 75 feet laterally upland from the mean high water. Within the waters described above, "wetlands" shall be protected as described in Chapters 2 and 9.

As used in this Policy, "navigable" shall include the following estuarine river systems in Martin County; St. Lucie River, Indian River and Loxahatchee River, including canals, tributaries and sovereign submerged lands regardless of the existence of a lease, easement or license.

For purposes of applying a shoreline protection zone, the term "navigable" shall not include: surface waters of the state that are connected to estuarine waters by a weir or other manmade structure, such as the S-80 lock; and ditches, swales and other constructed conveyances that are connected to the estuary by a pipe.

(1) There shall be no exceptions to this requirement reductions to the size of the shoreline protection zone except as stated below that:

(a)  For lots of record (as of April 1, 1982) with an upland area of one acre or less, the landward extent of the shoreline protection zone shall be reduced to 25 feet. The shoreline protection zone shall not require additional “construction setbacks” from the shoreline protection zone. However, setbacks from property boundaries (pursuant to the zoning districts in Article 3, Land Development Regulations, Martin County Code) shall remain applicable. Erosion control devices shall be installed and maintained throughout the duration of any construction activities adjacent to the shoreline protection zone. The shoreline protection zone shall not be subject to a preserve area management plan (PAMP) unless a PAMP has already been established pursuant to a development order, prior to August 13, 2013.

(b) Replacement of existing structures within the shoreline protection zone shall not be subject to the a 75 foot shoreline protection zone.

(c)  Non residential lots of record (April 1, 1982) more than one acre in size with hardened shorelines may reduce the shoreline protection zone from the mean high water line to 50 feet.

(d) Development within the shoreline protection zone may to provide reasonable access to the water, such as, Bbridges, docks, elevated walkways and boat entry facilities. Access shall be allowed when a plan for the proposed development demonstrates the need for access and alteration of the shoreline protection zone is minimized. Water access shall be perpendicular to the shoreline and shall be limited in width to 60 feet for Marine Waterfront Commercial Future Land Use, 150 feet for Institutional Future Land Use, and 12 feet for other development.

(e)  Existing facilities within the shoreline protection zone may be maintained, rebuilt or reconstructed within the existing foot print.

(f)  Removal of exotic vegetation or planting of appropriate native vegetation shall be allowed.

(g) Where an existing master site plan which is in compliance with its original timetable and has been found to be in compliance with policies in effect at the time of approval, specifies a shoreline protection zone which differs from policies in effect at the time of final site plan approval, the shoreline protection zone specified in the approved master site plan shall be deemed consistent with this policy.

(h) Single-family residential lots of record on plats approved after April 1, 1982 may be developed in accordance with the regulations (buffer, transition zone, setback, shoreline protection zone and performance criteria) in effect at the time that the plat was approved.

(i)   For residential lots of record (as of April 1, 1982) with an upland area of more than one acre but not more than two acres, the landward extent of the shoreline protection zone may be reduced to less than 75 feet but shall not be reduced to less than 25 feet for either primary or accessory structures. New principal structures on lots shall maintain a shoreline protection zone from mean high water equal to or greater than the average shoreline protection zone of the nearest principal residences on adjacent lots. The average shoreline protection zone of the nearest principal residences on adjacent lots shall be determined by measuring from the point of each of the existing principal residences nearest to mean high water.

Note for (i) above: Staff has issued a supplemental memo recommending an additional exception to the shoreline policy in ch 2 that allows vacant residential waterfront lots platted prior to 1982 to reduce the shoreline protection zone to match the existing setbacks on either side of the lot.

(2) Commercial marinas are water-dependent uses requiring proximity to the water. Commercial marinas that exist as of August 13, 2013 may be reconfigured and redeveloped, as provided below:

(a) Impervious surfaces and other encroachments in to the shoreline protection zone may be relocated within the shoreline protection zone provided, there is no net increase in the square footage of impervious surfaces.

(b) Planting of native vegetation shall not be required landward of vertical seawalls where no such vegetation exists.

(c) Existing commercial marinas shall maintain existing access through the shoreline protection zone for water-dependent uses and this area shall not be limited to the 60 foot wide access provided for properties designated for marine waterfront commercial use, Policy 8.1C.1.(3) (c) 2).

1) Where redevelopment of existing commercial marina developments requires relocation of boat entry facilities, access through the shoreline protection zone may be expanded beyond existing access where clear need is demonstrated.

2) Where redevelopment of existing commercial marina developments is proposed, existing pedestrian access and access for loading between vehicles and vessels within the shoreline protection zone may be maintained.

(d) Commercial marinas with existing manmade boat basins or boat “cut-outs” may be allowed to reduce or eliminate the manmade basin provided, there is no impact to wetlands, seagrass or oyster beds. Elimination of a basin shall not permit the creation of upland area waterward of the natural shoreline, prior to man-made impacts.

(e) Any redevelopment, as authorized in this section, shall demonstrate that impact to the estuary from stormwater run-off will meet the minimum storm water requirements (in place at the time of the proposed redevelopment) for rate, quantity, quality, and timing of the discharge.

(f) The shoreline protection zone shall not require additional “construction setbacks” from the shoreline protection zone. However, setbacks from property boundaries (pursuant to the zoning districts in Article 3, Land Development Regulations, Martin County Code) shall remain applicable. Erosion control devices shall be installed and maintained throughout the duration of any construction activities adjacent to the shoreline protection zone. The shoreline protection zone shall not be subject to a preserve area management plan (PAMP) unless a PAMP has already been established pursuant to a development order, prior to August 13, 2013.

Policy:2.2C.10. Hardening of the shoreline shall not be allowed without a clear demonstration that there is continuing erosion that causes a significant threat to property. Hardening shall be a last resort where it can be demonstrated that other options which maintain natural vegetation and a sloped shoreline will not provide protection. Bulkheads or vertical seawalls may be allowed without a demonstration of significant erosion for lots of record as of 1982 fronting on man-made canals where 75% of the canal lots have permitted seawalls.

Measure: The county shall request an annual report from the Corps of Engineers and the SFWMD on progress in implementing the Indian River Lagoon Plan and other components of CERP which affect Martin County.

Measure: Martin County’s state legislative delegation and Congressmen and Senators shall be asked to provide the County with an annual Report on the progress of CERP and the Indian River Lagoon South component.

Measure: All development approvals shall show the rate, timing, and volume of runoff for the completed project based on the approved stormwater management plan, as well as the same indicators for existing use and for the area in its natural state. Staff shall work with project engineers to provide an agreed on form and process for said reports. Development approvals shall show water quality data for present use, post development use and the property in its natural state. The data shall include: total suspended solids, total phosphorous and total nitrogen. Where oils and grease, heavy metals, or other pollutants are expected as a result of the development, such information should be clearly shown.

Measure: The Growth Management Department and the Engineering Department shall provide an annual report showing mangroves, seagrass beds, oyster bars, or natural shorelines where development approvals in the preceding year  allowed alteration or or negative impacts. Recommendations for changes to the CGMP that would support the remediation of said impacts and which would prevent such impacts in the future shall be included in the report.

Measure: Martin County shall work with state and federal agencies to monitor discharges to major canals leading to the St. Lucie River. The goal of said monitoring shall be to identify problem areas and create strategies to reduce those problems.

Objective 2.2D. Martin County shall protect and restore the Loxahatchee River, Florida’s first National  Wild and Scenic River.

Policy:2.2D.1. Martin County shall support implementation of the Loxahatchee River Watershed Restoration Project which is a component of the Comprehensive Everglades Restoration Plan.

Policy:2.2D.2. In considering amendments to the CGMP in the watershed of the Loxahatchee River which increase the intensity of use, the Board shall consider whether the more intense land use will negatively impact the ability to restore natural timing, volume, and water quality to the Loxahatchee River. Figure 5. From the 2010 Loxahatchee River National Wild and Scenic River Management Plan shall be used to identify the boundary of the Loxahatchee River Watershed in unincorporated Martin County. The 2010 Loxahatchee River National Wild and Scenic River Management Plan is a public record available from the DEP and SFWMD.

Policy:2.2D.3. Through its land use authority, under Chapter 163, the county shall ensure the impacts of development approvals do not diminish the water supply during the dry season for the Loxahatchee River and its associated wetlands.

Objective 2.2E. Within the limits of state law, Martin County shall use its land use authority to protect the freshwater aquifer.

Policy:2.2E.1. Seasonal water tables shall be preserved, and protected, and/or enhanced. Water withdrawals from the aquifer shall not be allowed to change normal seasonal variation of wetland water levels. The County will use its land use authority under Chapter 163 to implement this policy.

Policy:2.2E.2. The aquifer shall be protected from pollution and salt water intrusion.

Measure: The County shall work with the United States Geological Survey and the South Florida Water Management District to obtain information for use in the Evaluation and Appraisal Report (EAR) which tracks trends in water levels, pollutant levels and salt intrusion in the surficial aquifer. 

Goal 2.3. Martin County shall promote orderly and balanced economic growth while protecting natural resources, enhancing the quality of life in Martin County, and providing prudent fiscal management.

Objective 2.3A. Martin County shall adopt land use regulations that will encourage economic development to the extent consistent with the goals, objectives and policies of the CGMP.

Policy 2.3A.1. Martin County shall establish reasonable, clear, and objective standards for issuing permits for non-residential uses.

Policy 2.3A.2. Application requirements shall be simplified in industrial parks for where property has been subdivided and facilities are available.

Policy 2.3A.3. Martin County shall create a concurrency data base to make accurate information on concurrency available to applicants for development approval.

Measure: The Growth Management Department shall maintain a list of industrial subdivisions that have all facilities available. A list shall be maintained of areas of vacant Industrial land use that are not available for immediate use along with a report on how their deficiencies can be remedied.

Objective 2.3B. Martin County, in conjunction with the developer, shall provide public facilities necessary for development concurrent with the need for those facilities.

Policy 2.3B.1. Martin County shall enforce the concurrency standards for sanitary sewer, solid waste, drainage, potable water, parks and recreation, and transportation facilities (including mass transit where applicable) as detailed in Chapter 14, Capital Improvements, as critical components of maintaining the quality of life for existing and new residents as well as providing balanced economic growth. Standards shall be updated as needed to ensure that an acceptable level of service is maintained for public facilities.

Policy 2.3B.2. Martin County concurrency standards shall:

(1) Provide adequate facilities for businesses to function efficiently according to adopted levels of service;

(2) Ensure a quality of life acceptable to county residents; and

(3) Ensure that growth will pay for itself.

Policy 2.3B.3. All development must meet the concurrency requirements of this Plan.

Policy 2.3B.4. No FLUM amendment or text amendments shall lessen the requirements of this Plan to provide an acceptable level of public services for the people of Martin County unless mandated by state law. 

Measure: The Growth Management Department shall coordinate with other departments to provide annual reports listing Level of Service deficiencies and proposals to remedy those deficiencies. The report shall analyze reasons for service deficiencies and propose strategies to avoid future deficiencies.

Objective 2.3C. Martin County shall use objective indicators to measure economic health.

Policy 2.3C.1. The county shall annually update and maintain information from Florida Abstracts and other sources on the economy. Sources shall be identified which give consistent accurate information over time.

Measure: The county shall establish and maintain current accurate information on economic indicators. Unemployment rate, agricultural and non-agricultural jobs, average annual wages, median household income, tax base in relation to population, total ad valorem taxes in relation to population, home ownership, foreclosures and homes for sale and other economic information shall be collected from sources which can be shown to be the best available data on a continuing basis.

Objective 2.3D. Martin County shall coordinate with and support the county’s public schools as an incentive to business creation, expansion, and relocation.

Policy 2.3D.1. The county shall work with the Martin County School District and Indian River State College to showcase the high caliber of county schools.

Policy 2.3D.2. Martin County schools shall be used as an incentive to business creation, expansion, and relocation.

Policy 2.3D.3. Impact fees shall be kept current to avoid school overcrowding.

Goal 2.4. Prudent fiscal management shall be a primary goal in all County actions and in all development approvals.

Objective 2.4A. Martin County shall limit local tax burdens while funding facilities and services needed to maintain the quality of life and support services necessary for growth.

Policy 2.4A.1. New development shall pay the cost of the facilities it requires. Impact fees, enterprise fund user charges, connection fees, and other user fees paid by new development shall be reviewed every two years to ensure that provision of capital improvements needed to address the impact of future development will not increase ad valorem tax rates.

Policy 2.4A.2. Impact fees shall be designed to make sure that there is a rational nexus between the fees collected and the impact of the project paying the fees. Fees collected for a category of public facilities must be expended for those kinds of facilities.

Policy 2.4A.3. The County shall ensure honesty and efficiency in all departments and agencies receiving county funds by requiring open meetings and transparency in decision making; by requiring strict conflict of interest and disclosure policies; and by requiring objective accountability for results.

Policy 2.4A.4. The County shall not waive impact fees for any project.  Where a super-majority of the county commission determines that a public purpose is being served, the commission may pay impact fees with other county revenues.

Policy 2.4A.5. Property with an agricultural tax classification may be granted a land use change which allows urban development provided any existing agricultural classification is removed at the first opportunity. Issuance of an agricultural classification by the Martin County Property Appraiser’s Office after a previous approval by Martin County of a FLUM amendment that allows urban development shall result in a County initiated plan amendment to rescind the prior FLUM amendment. This is in no way intended to prevent any landowner from taking advantage of state law in regard to the agricultural tax classification. These policies apply only to the county’s requirements for plan amendments.

Policy 2.4A.6. Martin County shall create and maintain a database for objective indicators of fiscal conservancy.

Measure: Each year the County will document the revenues and expenditures of impact and user fees in each category. The report shall include data on impact fees that were reduced or paid from County revenues and an accounting of how those costs will be paid. At least every two years impact fees will be adjusted so that they are fair and equitable and meet the requirements of this Plan.

Measure: The county shall annually report data on total ad valorem taxes and total ad valorem taxes per capita, water and sewer fees, gas tax revenue, and sales tax revenue.

Objective 2.4B. Martin County shall use the Capital Improvement Plan to ensure that concurrency management strategies are fiscally feasible and expenditures are properly prioritized to meet critical needs.

Policy 2.4B.1. All revenues in the CIP shall be from dedicated sources.

Policy 2.4B.2. Expenditures in the CIP shall be prioritized as follows:

(1) New public facilities and improvements to existing public facilities that eliminate public hazards;

(2) Repair, remodeling, renovation or replacement of obsolete or worn-out facilities that contribute to achieving or maintaining standards for levels of service adopted in this Comprehensive Growth Management Plan in accordance with standards;

(3) New or expanded facilities that reduce or eliminate deficiencies in levels of service for existing demand;

(4) Improvements to existing and new facilities that significantly reduce the operating cost of providing a service or facility or otherwise mitigate impacts of public facilities on future operating budgets;

(5) New or expanded facilities that provide the adopted levels of service for new development and redevelopment during the next 10 fiscal years, pursuant to Policy 14.1A.10, CGMP.

(6) New or expanded public facilities that are contained in a Community Redevelopment Plan and scheduled in the next five years;

(7) New facilities that exceed the adopted levels of service for new growth during the next five fiscal years pursuant to Policy 14.1A.10, CGMP.

Measure: The administrator shall report failures of the CIP to cover prioritized needs and shall propose solutions to prevent a recurrence of the problem.

Objective 2.4C. Martin County shall coordinate the timetables of developments with expected population projections so that development approvals are consistent with a fiscally feasible strategy for planning and construction of public facilities.

Policy 2.4C.1. Because excessive development approvals require capital expenditures on facilities that will not be needed, the county shall adopt a planning system to track residential development approvals and limit final residential development approvals scheduled for the first five years of the 15 year planning period, to 125% of the projected need for residential units for that period.

Policy 2.4C.2. Appropriate action shall be taken in a timely fashion to remove projects from the tracking list that are no longer active. An active residential development is a residential development that has final site plan approval and is meeting all requirements of the development order, including the timetable.

Policy 2.4C.3. The county shall limit commercial and industrial land use amendments to that needed for projected population growth for the next 15 years. This shall be related to the increase in developed commercial and industrial acreage in relation to population increases over the preceding ten years. Implementation of this policy shall be done through amendments to the Land Development Regulations. Amendments to the Land Development Regulations shall be undertaken within two years after the ordinance adopting this text becomes effective.

Policy 2.4C.4. Except for platted single family and duplex lots, no development order shall grant vested rights to any project beyond the last year of the CIP.

Measure: The Growth Management Department shall provide an annual report on the number of residential units approved that year in the Primary and Secondary Urban Service Districts each of the urban service districts and in the area outside the USDs Primary and Secondary Urban Service Districts. This shall include Master Plan approvals, platted lots, and final approvals for residential development. The report will include: data on units built in previously approved projects that are part of the active residential development inventory; an updating of vacant land in residential projects with final development approval; projects that have become inactive; vacant housing units not used by seasonal or permanent residents; and vacant residential single family and duplex lots.
