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 requests waiver because our boundary survey is greater than one year old. The survey is dated 2025/04/17. This is the same survey that was submitted with the preliminary plat.
LDC 6.13.7.B Geotechnical criteria
CODE states (1) Depth. Soil test borings shall be performed to a minimum depth of 10 feet below the proposed finished grade of the bottom of all retention/detention areas or the permanent pool elevation and once the data has been obtained the hole shall be backfilled and compacted. (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. (3) Infiltration/permeability tests. For retention/detention areas utilizing percolation or infiltration in the design model, there shall be a minimum of two infiltration rate tests for each retention/detention area. Data used for soil permeability testing or infiltration analyses for the retention/detention areas shall be signed and sealed by a professional engineer or professional geologist for both data and procedural accuracy. (4) Aquifer parameters. The estimated seasonal high ground water elevation and confining layer shall be clearly identified.
APPLICANT requests a waiver for the minimum number of borings and infiltration/permeability tests for our stormwater ponds. We currently have two soil borings within the ponds. At one point we had three, however, the County requested a redesign at the time of preliminary plat and the third boring subsequently falls outside of our new ponds. Considering the combined pond bottom area of 0.58 acres is just above the 0.5 acre threshold where a third boring is required, it was determined via correspondence with the reviewer that a waiver could be supported.
