§ 96-28. Streets; generally.

(a)

General. The character, width, grade and location of all streets and bridges shall conform to the standards in this section and shall be considered in their relation to existing and planned streets, to topographical conditions, to public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets. All bridges shall conform to the latest edition of the "Standard Specifications for Highway Bridges" adopted by AASHTO. Construction and material specifications for streets and bridges shall conform to "FDOT Standard Specifications for Road and Bridge Construction."

(1)

Thoroughfares in developments shall be planned in conformity with the transportation element of the comprehensive plan.

(2)

The proposed development's street layout shall be coordinated with the street system of the surrounding area or with plans for streets in said area on file with the city, if any.

(3)

Where, in the opinion of the development review committee (DRC), it is desirable to provide for future street access to an adjoining property, proposed streets shall be extended by dedication to the boundary of such property and a temporary paved turnaround provided.

(4)

All newly platted streets intended to serve residential uses shall be public. The DRC may recommend and the city commission may approve private streets for security purposes only, provided all such streets meet all design and construction criteria of this chapter, a permanent security post or posts are provided, and a condominium or homeowners association is created with all duties and powers necessary to ensure perpetual maintenance of such private roads. All streets shall be constructed to the exterior property lines of the development unless they are permanently terminated by a cul-de-sac or an intersection with another street.

(5)

Newly platted streets intended to serve business or industrial uses may be private if approved by the DRC. In such cases, all streets shall meet the design and construction criteria of this chapter unless overriding conditions, such as sharing entrances or parking areas, require different design criteria.

(6)

Private streets shall be an easement that has not been dedicated to the public and has not been accepted by the city commission for maintenance.

(b)

Traffic impact analysis. Unless waived by the DRC, the developer at his/her expense shall have a registered professional engineer qualified in traffic engineering prepare and shall provide the city with a traffic impact analysis when trip ends generated by the proposed development equal or exceed 1,000 trip ends per day, as determined from the "ITE Trip Generation Manual," or when determined to be necessary by the DRC, if less than 1,000 trip ends per day. The traffic impact analysis shall be submitted at the time of Preliminary Plat or FSP review, and shall follow the adopted MPO Transportation Impact Analysis (TIA) Methodology Guidelines as it may be amended from time to time.

(c)

Arrangement of streets. The arrangement of streets in a development shall:

(1)

Provide efficient and orderly hierarchy of streets;

(2)

Conform with official plans and maps of the city;

(3)

Be integrated with the existing and planned street system of the surrounding area in a manner which is not detrimental to existing neighborhoods;

(4)

Be such that the use of local streets by through or commercial traffic is discouraged;

(5)

When necessary, as determined by the DRC, provide at least two separate and remote entrances to a development, unless other provisions, such as easements, are made for emergency ingress and egress, and provided that such entrances will not adversely affect the overall street system;

(6)

Facilitate and coordinate with the desirable future development of adjoining property of a similar character and provide for local circulation and convenient access to neighborhood facilities.

(d)

Intersections. Street intersections shall be laid out as follows:

(1)

Streets shall intersect at an angle of 90 degrees, unless circumstances acceptable to the DRC indicate a need for a lesser angle of intersection.

(2)

Intersections of any streets with a thoroughfare shall be at least 660 feet apart, measured from centerline to centerline.

(3)

Property lines at street intersections shall be rounded with a minimum radius of 25 feet. A greater radius shall be required for angles of intersection less than 90 degrees.

(4)

The right-of-way width and pavement width shall be increased by at least ten feet on each side of an arterial street for a minimum distance of 150 feet from its intersection with another arterial street or thoroughfare, to permit proper intersection design.

(e)

Minimum right-of-way and lane widths. Street minimum rights-of-way and lane widths shall be as follows unless otherwise indicated or required:

(1)

Urban development. (Applicable to designated urban areas in the comprehensive plan).

Table 96-1: Urban Development
Minimum Right-of-Way
and Lane Widths

(f)

Additional right-of-way and/or pavement widths. Additional right-of-way and or pavement width may be required by the DRC to promote public safety and convenience or to ensure adequate access, circulation and parking. Whenever any street shows future need for improvement within the area to be developed, the appropriate right-of-way and pavement shall be dedicated. Where a proposed development abuts or contains an existing street of inadequate right-of-way or pavement width, additional right-of-way and pavement in conformance with subsection (e) shall be required for that development.

The thoroughfares shown on the thoroughfare system maps in the transportation element of the comprehensive plan of the city or the jurisdiction in which the roads are located, which are either located within or provide primary access to the area proposed to be developed, shall be conveyed or dedicated to the public by deed, or if acceptable to the city or other appropriate jurisdiction, by grant of easement.

Half streets shall be prohibited. Where a previously dedicated half street, paved or unpaved, abuts or is within a tract to be developed, the second half of the street shall be dedicated to the city and the full width shall be paved by the developer where the subject street is necessary for the development of the subdivision or overall traffic circulation.

On divided two-lane road, minimum pavement width for each lane shall be 14 feet, exclusive of curbs. Provisions for left turns storage, acceleration, deceleration, tapers or channels shall be provided as required by the city traffic engineer. Whenever an island is proposed in the center of a cul-de-sac turnaround, the pavement shall be 26 feet exclusive of curbs, if any.

(g)

Access. Access shall be provided as follows:

(1)

There shall be the minimum number of access points to adequately serve the development.

(2)

In order to provide ease and convenience in ingress and egress to private property and the maximum safety with the least interference to the traffic flow on thoroughfares, the number and location of driveways shall be regulated by the dedication of access rights to the city, and in accordance with sections 110-829 and 96-37.

(3)

Tapers, deceleration lanes, left-turn lanes, bypass lanes, median modifications or other facilities shall be provided as requested by the city traffic engineer to protect the safe and efficient operation of a thoroughfare.

(4)

Every lot or parcel shall have access from a public street.

(5)

All proposed lots or developments shall front on a paved road. Primary access to a subdivision or development shall be from a street paved to the standards of section 96-40. This street, if not already paved, shall be paved by the developer from the entrance of the development to the nearest public paved road.

(h)

Business/industrial and multifamily driveways and internal circulation.

(1)

Vehicular circulation must be completely contained within the property, and vehicles located within one portion of the development must have access to all other portions without using the adjacent street system.

(2)

Acceptable plans must illustrate that proper consideration has been given to the surrounding street plan, traffic volumes, proposed street improvements, vehicular street capacities, pedestrian movements and safety.

(3)

No driveway shall be constructed in the radius return of an intersection or within 50 feet of the tangent point of the radius return.

(i)

Pavement (or curb) radius returns at intersections. The minimum radius return of pavement edge, or back of curb, where used, at all typical intersections approximating a right angle shall be as follows:

Table 96-3: Minimum Radius Return of
Pavement Edge/Back of Curb

Category	Minimum Radius (feet)
2-lane access	30
Local to collector	35
Local or collector to arterial	40
Arterial to arterial	50

 

A taper or turn lane may be required on roads with a functional classification of collector or arterial, or a design speed of 35 miles per hour or greater. Other appropriate radii shall be subject to approval by the city traffic engineer for other than right-angle intersections.

(j)

Service drives. Where a development borders on or contains a railroad right-of-way, limited-access highway right-of-way, or arterial road right-of-way, the DRC may require a service drive or suitable provisions for future service drives approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land, as for park purposes in residential districts, or for business or industrial purposes in appropriate districts. Distances involving rights-of-way shall also be determined with due regard for the requirements of approach grades and future grade separations.

(k)

Street jogs. Street jogs or centerline offsets between streets shall be no less than 150 feet.

(l)

Cul-de-sac. Permanent dead-end streets shall not exceed 1,000 feet in length; however, the DRC may approve a cul-de-sac of greater lengths, where, due to topographical conditions, design considerations or the number of lots to be located on the street, a greater length may be deemed necessary. In the center of the turnaround, an unpaved island, surrounded by a curb, improved with grass and landscaping that will not interfere with sight distance, may be provided. Center islands shall have a diameter of not less than 17 feet.

(m)

Street grade. Minimum centerline grade for all streets with curb and gutter shall be two-tenths of one percent. Maximum centerline grades for arterial roads shall not exceed five percent. Maximum grades for all other streets shall not exceed eight percent. The centerline may be flat for all swale sections provided the swale grade is a minimum of two-tenths of one percent.

(n)

Design criteria. All proposed streets shall comply with the specifications contained in the "FDOT Minimum Standards for Streets and Highways."

(o)

Street names. Proposed streets which are obviously in alignment with other existing or approved named streets shall have the same name as the existing or approved streets. In no other case shall the name of a proposed street duplicate or be phonetically similar to existing or approved street names, irrespective of the use of alternative suffixes, such as "street," "avenue," "boulevard," "drive," "place," "court," etc. All street names shall require the approval of the city planning and development services department.

(p)

Street lights. All proposed urban and suburban development shall provide for street lighting installation. A petition for creation of a special assessment district for street lighting shall be submitted.

(1)

Installation of street lighting.

Arterials. Lighting units (22,000 lumen) along arterials must be spaced 100 feet to 150 feet on alternate sides of the street. All intersections must be provided with street lighting.

Collectors. Lighting units (16,000 lumen) along collectors must be spaced 200 feet to 250 feet on alternate sides of the roadway. All intersections must be provided with street lighting.

Locals. New street lights (9,500 lumen) on local streets must be provided at intersections or at points along the road such as sharp curves or existing overlength culs-de-sac where street lights would decrease the potential for accidents.

(2)

Installation procedures. Proposed street lighting along all public rights-of-way must be coordinated through the city. Street light installation orders are issued by the city's department of public works to initiate the process and must be requested by the developer through the city as soon as street construction plans are complete. All costs for new street lighting on public streets must be paid for by the developer.

(q)

Traffic signals. Traffic signals and other control devices shall be installed at locations determined by the DRC, where warranted, pursuant to any submitted traffic studies in accordance with "USDOT Manual on Uniform Traffic Control Devices."
