§ 9.04.00. Transportation Systems.
9.04.01 Road Location and Layout.
A.
Subdivisions.
1.
The primary objective of Subdivision design is to provide maximum livability. This requires a safe and efficient Access and circulation system. The following principles should be considered when developing the Subdivision design.
a.
Adequate vehicular and pedestrian Access should be provided to each Parcel.
b.
Circulation systems and Land-Development patterns should not deTract from the efficiency of bordering major Roads. This principal may involve control of Driveway, intersection placement, and full or partial control of Access. Land Development should occur so that no Parcels require direct Access to major Roads.
c.
Planning and Construction of Residential Roads should clearly indicate their local function. These Roads should have an appearance commensurate with their functions. They should not be overdesigned or overbuilt i.e. high speed, excessive width etc. Appurtenances should be in keeping with the Residential character.
d.
There should be a minimum number of intersections. Within the Subdivision and especially along abutting major Streets, intersections pose an accident potential. The fewer intersections there are, consistent with other requirements, the fewer accidents there should be.
2.
Road layout
a.
Where a proposed Subdivision is adjacent to, or encompasses, an Arterial or Collector Road, it Shall be planned so as to avoid having Lots fronting on the Arterial or Collector in such a manner as to derive Access from the Arterial or Collector.
b.
Proposed Roads Shall be adjusted to the contour of the Land so as to produce usable Lots and Streets of reasonable gradient.
c.
In order to provide continuity and improved traffic circulation within the vicinity, main Roadways within Developments should be interconnected. Roads with expected internally generated traffic volumes in excess of two thousand (2,000) ADT Shall have Roadways and/or Rights-of-Way extended to the boundary lines of the Property when extension is necessary to provide for normal circulation of traffic within the vicinity.
Subdivisions with smaller volume Roads and are located adjacent to or near proposed Roads identified in an adopted County Roadway plan, or are adjacent to an existing or planned Right-of-Way extension, Shall provide Road and/or Right-of-Way extensions if necessary for improved traffic circulation within the vicinity. Other Subdivisions with smaller volume Roads should, where feasible and consistent with the character of the Development, provide Road and/or Right-of-Way extensions if necessary for improved traffic circulation within the vicinity.
d.
Loop Roads and curvilinear Roads are recommended for Residential Roads to discourage excessive speeds, provide atTractive vistas and provide an integrated Road network.
e.
Temporary dead-end Roads may be Permitted if future Access is anticipated if it is provided with a temporary turn around Area which Shall meet the requirements of the County Engineer for design, Maintenance, and Removal. Permanent dead-end Streets, exclusive of Cul-de-sacs, Shall not be Permitted.
f.
Half Right-of-Way Shall not be Permitted unless contiguous to an existing Subdivision with an existing half Right-of-Way.
g.
Where necessary for design, Alleys may be provided to serve multiple Dwellings, business, Commercial and industrial area.
3.
Block layout.
a.
Residential Block length. In general, intersecting Streets, which determine Block length, should be provided at such intervals as necessary to meet existing Street patterns, topography, and requirements for safe and convenient vehicular and pedestrian circulation. Blocks, however, normally should not exceed one thousand two hundred (1,200) feet in length, nor be less then six hundred (600) feet in length. Straight lengths of Local Streets greater then one thousand (1,000) feet in length should be avoided where possible.
b.
Non-Residential Block length. Blocks intended for non-Residential uses should be of such length, width and other design as necessary for the prospective use, including adequate provision for Off-Street parking, loading and unloading of trucks, and limitation and control of vehicular Access points to adjacent Streets.
4.
Local Streets and Neighborhood Collector Roads. The primary function of Local Streets is service to abutting properties. Street widths, placement of sidewalks, pattern of Streets and number of intersections are related to safety and efficiency of Access to abutting Lands.
5.
The primary function of Neighborhood Collector Roads is to collect traffic from the Local Streets and provide a Connection to higher volume Roadways (feeder/distributor, Collector or Arterial).
6.
The following principles should be considered when designing Local Streets and Neighborhood Collector Roads:
a.
Local Street systems should be designed to minimize through traffic movements. Through traffic on Local Streets increases the average speed and volume and thus the accident potential, thereby reducing Residential amenities. Through traffic should be discouraged by creating discontinuities in the Local Street pattern, and by offsetting Local Street intersections.
b.
Local Street systems should be logical and comprehensible. The pattern of Local Streets and their names should be designed to satisfy the needs of visitors, delivery trucks, and emergency Vehicles as well as local residents. A reasonable repetition in Street pattern, or conformance to topography can help in achieving an understandable Street system. Streets which wander directionally or which turn back on themselves tend to be confusing and should be avoided except in small cluster Developments.
c.
The Local Street system should be designed for a relatively uniform low volume of traffic. To the extent possible, the design of the Local Street system should recognizes the need for Residential amenities along all Streets in the neighborhood. This suggests that the Street system should be designed for uniformly low volumes on all Streets after continuous Land Development is complete.
d.
Local Streets should be designed to discourage excessive speeds. Residential Streets should by designed to discourage fast movement (more than thirty (30) MPH), through the Use of curvilinear alignment and discontinuities in the Street system.
e.
It is desirable to design Local Streets so that anticipated traffic volumes will be in the range of approximately one hundred (100) to five hundred (500) V.P.D.
f.
Neighborhood Collector Roads should be designed to carry between five hundred (500) to one thousand five hundred (1,500) Vehicles per day.
B.
Site Plans.
1.
Every Site Shall have Access to a publicly owned and maintained Road or to a privately owned and maintained Road, Easement, or commonly owned Parcel. When the Site does not abut a publicly or privately owned Road, the Applicant must provide proof of Easement or common Ownership Parcel.
2.
Access to and from the Site Shall be designed and constructed in conformance with Section 9.05.00 Access Management.
3.
Access drives to and from the Site Shall be designed and constructed to provide a minimum width of ten (10) feet per lane.
4.
Site Plans Shall provide for the internal circulation of traffic in a safe, comprehensible, and efficient manner. All traffic circulation systems Shall be designed considering the provisions included in Section 9.04.01 and the Lake County Transportation Planning, Design and Construction Standards. The County Manager or Designee may, if deemed necessary, require a traffic Engineering analysis and/or specific design modifications regarding a Site Plan's internal traffic circulation system.
9.04.02 Planning, Design and Construction Requirements.
A.
General. The Professioanl Engineer of record is totally responsible for all Road and bridge design data and calculations, and for ensuring that the criteria contained in this Code are followed during design and preparation of Construction plan. Review and approval of design data and Construction plans by Lake County does not relieve the Professional Engineer of record of any responsibility.
B.
Technical standards. All Roadway and transportation planning, design, and Construction Shall conform to the requirement contained in the Lake County Transportation Planning, design and Construction standards.
9.04.03 Right-of-Way Provisions.
A.
Minimum Right-of-Way Standards. Minimum Right-of-Way widths Shall be based upon the classification of the Road, and Shall be in accordance with the following tables (Right-of-Way widths on State Arterial Roads may vary depending upon FDOT standards):
1.
Arterial Roads.
Classification Minimum Right-of-Way Width (ft) 4-Lane 6-Lane 8-Lane Freeway 216 240 264 Rural Arterial 200 200 — Suburban Arterial 174 200 — Urban Arterial 94 240 — 2.
Collector Roads.
Classification Minimum Right-of-Way width (ft) Curb & gutter Swales Major collector 80 100 Minor collector 70 80 3.
Local Roads
Classification Minimum Right-of-Way width (ft) Curb & gutter Swales Feeder/distributor 60 80 Neighborhood collect 50 66 Local street 50 66 Cul-de-sac (radius) 50 60 B.
Additional Right-of-Way. This Subsection Shall apply for all applications for Development Orders.
1.
Existing roads.
a.
Whenever a Property abuts an adjacent roadway with deficient Right-of-Way width, the County may require the dedication of additional Property to bring the existing Rights-of-Way up to standard widths, consistent with these standards.
2.
Future Arterial and Collector Roads.
a.
A proposed subdivision or Site Plan that abuts or encompasses an Area identified in the Lake County Road Construction Program as a future Arterial or Collector Road Shall provide for the dedication of Right-of-Way to meet the minimum Right-of-Way required by these regulations.
3.
Intersections.
a.
A proposed subdivision or Site Plan that abuts or encompasses an existing intersection Shall provide for the dedication of Right-of-Way for a rounded corner clip with a minimum radius of 25 feet.
b.
A proposed subdivision or Site Plan that abuts or encompasses an existing intersection Shall provide for the dedication of additional Right-of-Way of a length and width determined by the County Manager or Designee for the purpose of the installation of turn lanes. In no case Shall the additional Right-of-Way exceed a width of ten (10) feet and a length of five hundred (500) feet per each side of the Right-of-Way.
4.
Bicycle/Pedestrian Facilities.
a.
A proposed subdivision or Site Plan that abuts or encompasses an Area identified for improvement in an adopted Lake County Bicycle/Pedestrian plan or an adopted Rails to Trails plan Shall provide for the dedication of Right-of-Way to meet the minimum Right-of-Way required by the plans.
5.
Lot size and setback calculations.
a.
The dedication of the required Right-of-Way Shall not affect the calculations for Lot size or setbacks. For example, if a 25′ by 100′ Lot is required to dedicate one foot of Right-of-Way, the Lot Shall still be considered to have 2500 square feet (25 × 100 = 2500), not 2400 square feet (24 × 100 = 2400) and the Lot Shall still be considered to have a length of 100′, not 99′.
C.
Obstructions. It Shall be unlawful to cause to be created or constructed any Building, Structure, causeway or other obstruction (including but not limited to ditches) on the Right-of-Way of any public Road or Easement in Lake County, Florida, except Permitted activities.
