LDC 2.12.8 - Current boundary and topographic survey
CODE states Current boundary and topographic survey (one foot contour intervals extending 100 feet beyond the project boundary) based upon accepted vertical datum. Surveys will be less than 12 months old and accurately reflect current site conditions, meeting standards set forth in Ch. 5J-17 FAC. Alternate topographic data may be accepted if pre-approved by the Marion County Land Surveyor.
APPLICANT Request a waiver to allow for the use of the current boundary and topographic survey which is more than 12 months old will be submitted to DRC for consideration.
LDC 6.12.9- Subdivision roads and related infrastructure
CODE states A. In residential subdivisions, the road system shall be designed to serve the needs of the neighborhood and to discourage use by truck traffic and through traffic and still provide access to adjacent neighborhoods for emergency services. The use of neighborhood traffic calming devices such as traffic circles, cul-de-sac, etc. are encouraged in residential areas. B. Major local roads shall be identified on plans. C. All roads and related infrastructure within the proposed subdivision shall be designed, constructed, and paved to County specifications provided herein. D. The developer shall be required to design, construct, and pave to County specifications, one road from the subdivision to the nearest paved, public roadway with legal access, if such a road does not already exist. E. Roads and stormwater facilities within a subdivision shall be dedicated as either public or private. F. Public dedications shall be pre-approved by the Development Review Committee. If a MSBU is established as the maintenance and operation entity, roads and stormwater facilities can be platted as public. G. Cul-de-sac diameters to the right-of-way line shall not be less than 120 feet with a pavement radius of 40 feet for residential subdivisions and shall not be less than 120 feet to the right-of-way line with a pavement radius of 45 feet for commercial or industrial subdivisions. Refer to details in Section 7.3.1. A grassed island no greater than 50 feet in diameter may be constructed in the center of a cul-de-sac. H. Dead end roads shall not exceed 1,500 feet and shall have a cul-de-sac at the terminal end. Refer to details in Section 7.3.1. Dead end roads intended to provide future access to adjacent unplatted areas may be permitted without a cul-de-sac provided that no lots front thereon, the length does not exceed 1,500 feet, and appropriate temporary end-of-road markers are provided. I. The total perimeter of a block shall not exceed 4,500 feet. Larger block perimeters will be permitted for blocks surrounding or adjacent to natural or artificial features such as lakes, rivers, and golf courses where limiting block lengths are not feasible and impractical. J. Corner radii at the intersection of the two rights-of-way shall be not less than 25 feet. Minimum pavement radii shall be 40 feet for residential subdivisions and 50 feet for commercial or industrial subdivisions. K. Centerline radii shall be designed to accommodate the minimum design speed of 30 mph for subdivision local and minor local roads, 40 mph for major local and collector roads, and 45 mph for arterial roads in accordance with FDOT and AASHTO Standards. L. Evacuation routes for developments shall be indicated on the improvement plans.
APPLICANT Request a waiver to allow for the proposed design and posted speed will be submitted for consideration. Curve warning signage per FDOT Greenbook criteria is proposed as shown on Sheet 8.0.
LDC 6.12.9 (H) - Subdivision roads and related infrastructure
CODE states (H) Dead end roads shall not exceed 1,500 feet and shall have a cul-de-sac at the terminal end. Refer to details in Section 7.3.1. Dead end roads intended to provide future access to adjacent unplatted areas may be permitted without a cul-de-sac provided that no lots front thereon, the length does not exceed 1,500 feet, and appropriate temporary end-of-road markers are provided.
APPLICANT Requests a waiver to allow for the use of a hammerhead style intersection on dead end roads will be submitted to DRC for consideration. The proposed dead end segments will be less than 150' in length.
LDC 6.13.7(B)(2) - Geotechnical criteria
CODE states B. Minimum requirements. (2) Number of tests. At least two tests shall be performed within the boundary of each proposed retention/detention area. For each half acre of pond bottom area and for each lineal retention/detention area of 250 feet, an additional test shall be conducted. The County Engineer or his designee, may require additional tests if the initial tests indicate the need for them.
APPLICANT Requests a waiver to reduce the required number of borings from nine to seven for DRA-1. The provided soil borings stratification represents consistently the subsurface soils and groundwater conditions across the area and provide sufficient information for design.
