§ 23-303. Streets.  


Effective on Tuesday, July 7, 2015
  • All streets shall be constructed in accordance with the standards of this section, unless specifically waived for a planned development project. All streets shall be public unless approved as private streets in a planned development project pursuant to section 23-224.

    Sec. 23-303.1 Street layout. New streets shall extend existing street grids and patterns where feasible. Integrating new streets into the surrounding roadway network is favored over enclosed communities.

    a. The street layout of a subdivision shall provide for the continuation or projection of streets already existing in areas adjacent to the areas being subdivided unless the approving body deems such continuation or extension undesirable for specific reasons of topography or design.

    b. Where, in the opinion of the approving body, it is desirable to provide street access to adjoining properties, proposed streets shall be extended by dedication to the boundaries of such properties. Where the approving body deems it necessary, such dead-end streets shall be provided with a temporary turnaround having a radius of at least fifty (50) feet.

    c. The street system for the proposed subdivision shall provide for extending existing streets at the same or greater width, but in no case shall a street extension be of less width than the minimum width required by these land development regulations for a street in its category.

    Sec. 23-303.2 Street classification system.

    a. Street classification system. The street classification system is established consistent with the Transportation Element and map of the Comprehensive Plan to ensure the expansion of a roadway network adequate to serve the needs of future development. The roadway functional classifications group streets and highways according to the character of service they are intended to provide in relation to the total road network. The Federal Highway Administration defines the  basic categories as follows:

    Functional System

    Services Provided

    Arterial

    Provides the highest level of service at the greatest speed for the longest uninterrupted distance, with some degree of access control.

    Collector

    Provides a less highly developed level of service at a lower speed for shorter distances by collecting traffic from local roads and connecting them with arterials.

    Local

    Consists of all roads not defined as arterials or collectors; primarily provides access to land with little or no through movement.

    b. Classification of Lake Wales Streets

    Streets providing service within the city are classified as arterials, major or minor collectors, and local roads as follows:

    1. Arterial highways. Arterials are part of a network of continuous routes serving substantial statewide travel by connecting urbanized areas." The existing arterials within the city include:

    State Road 60

    U.S. Highway 27

    2. Major collector roads. A major collector means a street which conducts moderate volumes of traffic between arterials and minor collectors or local streets and also provides access to abutting properties. Major collectors shall connect to arterials or other major collectors at both ends.

    Major collectors in and immediately outside of the city that are part of the county road system include:

    Buck Moore Road between Burns Avenue and State Road 60 (CR 17-B)

    Burns Avenue, eastward from S.R. 17 (CR 17-A)

    Central Avenue between U.S. 27 and S.R. 60

    Eleventh Street southward from S. R. 60 (CR 17-B)

                    Masterpiece Rd. from Buck Moore Rd. to city limit

    Mountain Lake Cut-off Road

    Chalet Suzanne Road eastward from U.S. 27 (CR 17-A)

                    State Road 17(Alt. 25) 

    Thompson Nursery Road westward from U.S. 27

    3. Minor collector roads.

       Any new minor collector shall connect to another minor collector, an arterials, or a major collector at each end. Minor collectors shall not be dead-ends and shall not terminate at a local street.

     The city street system includes a gridwork of street classified as minor urban collectors, including:

    Campbell Avenue between Marietta Street and Eleventh Street

    Central Avenue between U.S. 27 and Lake Shore Blvd.

    Dr. Martin Luther King Blvd. between Dr. J.A. Wiltshire Avenue and S.R. 60

    Dr. J.A. Wiltshire Avenue between G Street and North Wales Dr.

    E Street between Florida Avenue and Dr. J.A. Wiltshire Blvd.

    Eleventh Street between Lakeshore Blvd. and S.R. 60

    Euclid Avenue between Seventh Street and Eight Street

    First Street between Dr. J.A. Wiltshire Blvd. and Winston Avenue

    Grove Avenue between 9th Street and 11th Street South

    Hunt Brothers Road between US Highway 27 and City limit

    Lake Shore Blvd.

    Marietta Street from Lake Shore Blvd. to Campbell Avenue

                    Mountain Lake Cut-off Road from U.S. 27 to S. R. 17 

    Ninth Street South south of Cohasset Avenue

    North Wales Drive between Burns Avenue and Lake Shore Blvd.

    Orange Avenue between Wetmore Street and S.R. 17

    Palm Avenue

    Stuart Avenue between Dr. Martin Luther King Blvd. and S.R. 17

    Third Street between S.R. 17 and Winston Avenue

    Tillman Avenue between S.R. 17 and Wetmore Street

    Tower Blvd. between Burns Avenue and Lake Shore Blvd.

    Wetmore Street between Sessoms Avenue and Briggs Avenue

    4. Local street. Local streets provide connections between individual properties and collectors or arterials. A local street is a route that has the function of providing accessibility to individual parcels of property in residential areas. Local streets carry light volumes of traffic and should be designed to discourage through traffic and encourage low vehicular speeds. Local streets existing in the city are all of those street not listed in this subsection as arterials, major collectors or minor collectors.

    Sec. 23-303.3 Street Access Requirements.

    a. Adequate access. Approval of any new development or expansion of an existing development shall be contingent upon provision of adequate access as provided in this section. "Adequate access" shall be determined by the permitting authority based upon the standards for streets in this section and in accordance with the concurrency requirements of article VII, div. 1.

    1. No subdivision or planned development project shall be approved by the City Commission unless there is adequate access to the property via existing public streets or a commitment has been made by the applicant or by the city, county, or state in the applicable capital facilities plan, to render the access adequate to serve the proposed development at the level of service standards required under article VII of this chapter, concurrent with development of the property.

    2. No building permit or site plan approval pursuant to section 23-222 shall be issued for construction or placement of a building on a lot unless that lot has adequate access. Provided the concurrency requirements of article VII are met, access shall be deemed adequate if the lot has the required frontage on a public street constructed to city standards or a private street meeting the standards required by the city at the time of its approval for construction. If the street is unpaved, or does not meet other design requirements of this section necessary for adequate service to the proposed development, the administrative official, or the planning board, as applicable, shall require the applicant to upgrade the street to provide adequate access, unless the improvements are scheduled by the city, county, or state, and will render access adequate at the time the proposed structures are occupied.

    b. Development access requirements. New development shall not be approved unless the development has or will have access to streets to serve that development, based on the following criteria:

    1. Commercial, industrial, and professional development.

    A. Developments on two (2) acres or less may be accessed from local streets. Where parcels proposed for development have multiple frontages, access from a side street is encouraged.

    B. Developments on parcels larger than two (2) acres and commercial, industrial, or professional complexes and subdivisions shall provide a consolidated entrance from an arterial or major collector road and provide a minor collector road within the development to access individual lots, buildings, or groups of buildings. The planning board may require the collector road to meet the standards for a major collector and may require additional entrances for large developments.

    C. No entrance road shall have driveways or parking lot entrances to individual parcels located within one hundred fifty (150) feet of its intersection with an exterior roadway.

        2. Residential development. Streets within new residential developments shall be designed to provide local streets within neighborhoods and collector roads to connect  neighborhoods to major collectors and arterial streets, within and outside of the development.

        A. No new residential subdivision or planned development with more than ten (10) lots or multi-family development with more than twelve (12) units shall be approved with primary access from a local street.

        B. No new residential lots or multi-family buildings shall have direct access to an arterial or major collector street. Collectors and local streets shall be provided within such developments for access to individual lots and buildings.

        C. No lots in new residential developments and no new multi-family buildings shall be approved or permitted on a local street unless the distance via local streets from the site to a minor collector street or street of higher classification is one thousand two hundred (1,200) feet or less.

        D. A collector street within a new residential development shall meet the standards for a major collector if it serves five hundred (500) units or more.

    Sec. 23-303.4 Entrance roads, intersections and blocks.

    a. Entrance road requirements.

    1. Distance of cross streets from project entrance. In any residential or non-residential development, a minimum distance of one hundred fifty (150) feet is required between the intersection of any entrance road to the development with a roadway exterior to the project and the intersection of a cross street or parking lot access. In residential developments with over one hundred (100) dwelling units, the minimum distance shall be increased by fifty (50) feet for every one hundred (100) dwelling units, rounded off to the nearest one hundred (100) dwelling units, with a maximum of four hundred (400) feet.

    2. No new residential development or neighborhood with more than fifty (50) dwelling units shall be approved with only one (1) entrance.

    3. Primary entrance roads are those that provide the main access to a residential development or any entrance from an arterial or major collector street. Secondary entrances are those that provide access to a residential development in addition to the primary entrance or entrances. The following standards shall apply to all residential developments with over fifty (50) dwelling units:

    i. An entrance shall be provided to each collector road on which the development has frontage.

    ii. At least one (1) primary entrance shall be provided to a residential development, except that those with fewer than ten (10) single-family dwelling units or twelve (12) multi-family dwelling units are not required to meet this requirement unless it is feasible to extend the entrance street to serve additional development in the future.

    iii. Primary entrance roads shall be designed to meet the standards for a minor collector street, with no driveways to individual lots located on the entrance road. The required length of a primary entrance road shall be proportional to the number of dwelling units within the development:

    TABLE – DWELLING UNITS AND REQUIRED LENGTH OF ACCESS ROAD

    Number of dwellings

    Length of Primary Entrance Road

    (Meeting major collector design standards)

    Up to 100

    350 feet

    iv. A secondary entrance shall be provided for any development with over fifty (50) dwellings. A secondary entrance shall meet the requirements for a minor collector.

    b. Block length. Block lengths shall not exceed one thousand two hundred (1,200) feet or be less than four hundred (400) feet.

    c. Angle of intersection. Streets shall intersect as nearly as possible at right angles and no intersection shall be at an angle of less than sixty (60) degrees.

    d. Curb radii. Street curb intersections shall be rounded by radii of at least twenty (20) feet. When the smallest angle of street intersection is less than seventy-five (75) degrees, the director of public works may require curb radii of greater length. Wherever necessary to permit the construction of a curb having a desirable radius without reducing the sidewalk at a street corner to less than normal width, the property line at such street corner shall be rounded or otherwise set back sufficiently to permit such curb construction.

    Sec. 23-303.5 Dead-end streets (culs-de-sac). No collector or arterial street shall be a dead-end street. Dead-end streets shall not exceed nine hundred (900) feet in length. All dead-end streets shall have a T or L shaped turnaround area at the terminus unless a turnaround is required for fire apparatus per the following criteria.

    a. Where a cul-de-sac exceeds one hundred (150) feet in length, an approved turnaround for fire apparatus shall be provided at the closed end. Said turnaround shall have a minimum centerline radius of fifty (50) feet. Radius measurement shall not include curb, greenway or sidewalk. A landscaped center island is required. The maximum radius of a center island on a cul-de-sac with a minimum centerline radius shall be fourteen (14) feet.

    b. Where a cul-de-sac exceeds three hundred (300) feet in length, an approved turnaround for fire apparatus shall be provided at the closed end. Said turnaround shall have a minimum centerline radius of sixty (60) feet. Radius measurement shall not include curb, greenway or sidewalk. A landscaped center island is required. The maximum radius of a center island on a cul-de-sac with a minimum sixty-foot radius shall be twenty-four (24) feet.

    Sec. 23-303.6. Right-of-way and pavement width. The following shall be the required right-of-way and pavement widths for the street classification categories:

    Local Street 50 feet 12 feet 18 inches 20 mph

     

     

    Sec. 23-303.7 Pavement specifications. Street pavement shall be as required by the director of public works. Pavement shall be designed to carry the expected traffic loads and shall conform with current standard specifications for city streets. All street pavements shall be of a stable type. Loose aggregate will not be considered a completed pavement.

    Sec. 23-303.8 Curbs and gutters. Curbs and gutters shall be provided on all streets. Vertical curbs shall be not less than six (6) inches in height and Miami curb shall not be less than three (3) inches in height. All curbs shall conform with the design standards established by the director of public works. Backfill shall be higher than the curb and shall slope toward the curb in order to ensure that surface water drains into the storm drainage system.

    Sec. 23-303.9 Sidewalks. Sidewalks constructed in accordance with this section shall be provided in all new developments and along all streets on which a development has frontage, unless a specific waiver is granted. City commission approval is necessary for any waivers of sidewalk construction requested with preliminary subdivision plats or planned development project plans. Compliance with this section is also required as a condition of approval of any site plan, including a site plan for a change of use, unless a specific waiver is granted by the planning board or administrative official as provided in this section. Planning board approval is required for waivers of sidewalk construction with major site plans or special exception use permits; the administrative official may grant waivers with approval of minor site plans and changes of use.

    A waiver may be granted in cases where the where the applicable permit granting authority deems the sidewalk to be unnecessary because of adequate pedestrian accommodations in the development or neighborhood or deems the cost of the improvement to be unreasonable in light of the magnitude of the change triggering the site plan review. The requirement for construction of sidewalks along arterial and major collector roadways may also be waived where there are no existing sidewalks to extend, provided the developer contributes funds to the city equivalent to the cost of paving the applicable length of five-foot concrete sidewalk, such funds to be used by the city to construct or repair sidewalks elsewhere within the city. Payments in lieu of construction shall be based upon prices in contracts currently available for city construction of sidewalks to city standards.

    a. Sidewalks shall be provided on at least one (1) side of all local streets and minor collectors and on both sides of arterials and major collectors. In the C-1 and C-2R districts, sidewalks shall be provided on both sides of the street, regardless of the street classification.

    b. Sidewalks shall be concrete and shall be a minimum of four (4) inches thick. Sidewalks shall be a minimum of five (5) feet wide in residential areas and eight (8) feet wide in mixed use and non-residential districts.

    c. Except in the C-1 district, there shall be at minimum a three-foot wide strip of landscaped area (as defined in section 23-307) between the sidewalk and curb in which a tree as defined in section 23-307 shall be planted every fifty (50) feet, at minimum. In planned development projects where adequate provision for pedestrian circulation is provided, the requirements of this section may be modified by the approving body.

    d. Sidewalks shall be constructed as part of the street construction in a subdivision or planned development project unless surety has been accepted by the city commission to cover the cost of sidewalks, in which case, the sidewalks shall be completed in segments as adjacent buildings are completed. Certificates of use may be denied on properties where the sidewalk serving the property has not been completed. As part of the approval of a permit for a construction or alteration of a structure or parking area, the administrative official may require the construction or reconstruction of sidewalks in order to fulfill the requirements of this section.

    c. Street jogs with center line offsets of less than one hundred twenty-five (125) feet shall not be made.

    d. Every change in grade shall be connected by a vertical curve constructed so as to afford a minimum sight distance of two hundred (200) feet, said sight distance being measured from a driver's eyes, which are assumed to be four and one-half (4½) feet above the pavement surface, to an object four (4) inches high on the pavement. Profiles of all streets showing natural and finished grades, drawn to scale, may be required by the director of public works.

    Sec. 23-303.11 Grades. All streets shall be designed so as to provide for the discharge of surface water from the pavement and from the right-of-way by grading and drainage facilities. The minimum street grade required for adequate drainage shall be as approved by the director of public works.

    a. The minimum grade of all streets shall be 0.3 percent unless specifically approved by the director of public works.

    b. Streets shall be designed so as to make them flood-free in order that properties served by such streets will not be isolated by floods. In flood-prone areas, the director of public works may require profiles and elevations of streets in order to determine the adequacy of design. Fill may be permitted by the director of public works provided that it does not adversely affect flood conditions of the surrounding properties. Street construction shall comply with Art. IV, Div. 1.Development in Flood Prone Areas as applicable.

    c. All streets shall be graded to their full widths so that pavements and sidewalks can be constructed on the same level plane. Deviation from this standard due to special topographical conditions will be allowed only with the specific approval of the director of public works.

    1. Preparation of the subgrade. Before grading is started, the entire right-of-way area shall first be cleared of all tree stumps, roots, brush and other objectionable materials and of all trees not intended for preservation. The subgrade shall be properly shaped, rolled and uniformly compacted to conform with the accepted cross section and grades.

    2. Cuts. In cuts, all tree stumps, boulders, organic material, and other objectionable materials shall be removed to a depth of at least two (2) feet below the grade surface. Rock, when encountered, shall be scarified to depth of at least twelve (12) inches below the graded surface.

    3. Fills. In fills, all tree stumps, boulders, organic material, soft clay, spongy material and other objectionable materials shall be removed to a depth of at least two (2) feet below the natural ground surface. This objectionable material as well as similar material from cuts shall be removed from the right-of-way area and disposed of in such a manner that it will not become incorporated in fills or hinder proper operation of the drainage system.

    Sec. 23-303.12 Street lighting. Street lights shall be provided along all vehicular and pedestrian ways in all subdivisions and planned development projects. Light poles shall not exceed 14 feet in height and shall be located to provide sufficient lighting along all pedestrian pathways and streets. The style and placement of street lights shall be approved by the city prior to installation. In new developments, the style and placement shall be shown on the site development plans and reviewed in accordance with section 23-217. Street lights shall be located so as not to encroach on sidewalks.

    Sec. 23-303.13 Street names.

    a. Proposed streets which are obviously in alignment with other already existing and named streets shall bear the names of such existing streets.

    b. The name of a proposed street which is not in alignment with an existing street shall not duplicate the name of any existing street in Polk County irrespective of the use of the suffix street, avenue, boulevard, drive, place, court, lane, road or similar suffix.

    Sec. 23-303.14 Dedication of streets and utilities in subdivisions. All streets and utilities shall be dedicated to the city at the time of final plat approval of the subdivision unless the streets have been approved as private streets in a planned development project pursuant to section 23-224.

    a. Dedication of right-of-way for new streets. The right-of-way for new streets to be dedicated shall be as follows:

    TABLE 23-303C
    RIGHT-OF-WAY DEDICATION REQUIREMENTS

    STREET CLASSIFICATION* RIGHT-OF-WAY WIDTH
    Arterial 120 feet
    Major Collector 84 feet
    Minor Collector 66 feet
    Local Street 50 feet

     

     

    *See § 23-303.2 for definitions of these street categories.

    b. Dedication of right-of-way for existing streets. Subdivisions platted along existing streets shall dedicate additional right-of-way if necessary to meet the minimum requirements for new streets set forth in Table 303C above.

    1. The entire minimum right-of-way width shall be dedicated where the subdivision is on both sides of an existing street. When the subdivision is located on only one (1) side of an existing street, one-half (½) of the required right-of-way width measured from the center line of the existing street shall be dedicated.

    2. Dedication of one-half (½) of the right-of-way for proposed streets along boundaries of land proposed for subdivision shall be prohibited except for arterial streets.
