SECTION FOUR: Article IV, Section 22-112, Construction Requirements for the Construction of Excavations, of the Code of Laws and Ordinances of Collier County, Florida, is amended as follows: Sec. 22-112. Construction Requirements for tile CaRlltmetiaR af Excavations. 8 Words struc); tHrsugR are deleted, words lInderlined are added. All requirements of the South Florida Water Management District, Permit Information Volume IV, along with the following requirements, shall apply to all excavations. (I) Setbacks. Excavations shall be located so that the control elevation contour of the excavation shall adhere to the following mmllnum setback requirements: Exception, where an excavation crosses common parcel or propelty lines. the sethack requirements are exempt at the contiguous propertv lines. a. Fifty feet from the right-of-way line or easement line of any existing or proposed, private or public, street, road, highway or access easement. Exceptions to the above- referenced setbacks may be developed and shall be subject to final approval by the development services administrator or his designee. Said exceptions shall he based upon recognized standards for traffic engineering and road design (AASHTO and/or Manual of Uniform Minimum Standards for Design, Construction and Maintenance for Streets and Highways, State of Florida) and shall incorporate such factors as road alignment, travel speed, bank slope, road cross section, and need for barriers. However, lakes immediately adjacent to "T intersections" shall be located , based on a specific design analysis by the applicant's engineer which provides for safety and traffic considerations at the intersection. h. Fifty feet from side, rear, or abutting propelty lines, except where the excavation IS located in agriculturally or industrially zoned districts abutting a residentially zoned district, the sethack shall be 100 feet from the residentially zoned property. Exceptions to these setbacks may be granted if the following criteria are met: installation of proper fencing (minimum feHr six feet chain link), herms, walls, or other engineered protective measures for the portion of the property line within 100 feet of the lake. The minimum setback from any property line to the control elevation contour shall be 20 feet. c. From jlllisdictional wetlands setbacks will be determined using standards set by SFWMD or the Depmtment of Environmental Protection, as applicable. (2) Side slopes. The finished side slopes of the excavated area, expressed as the ratio of the horizontal distance in feet to one foot of vertical drop, shall be as follows: A maximum four to one slope shall be graded from the existing grade to a hreakpoint at least ten feet helow the control elevation. Below this breakpoint, slopes shall be no steeper than two to one. a. All governmg side slopes shall be considered from 20 feet outside the control elevation contour of the resulting excavation. b. If rock, homogenous to the bottom of the excavation, is encountered at any elevation above the breakpoint, then the remaining slope below the breakpoint shall be no steeper than 0.5 to one. If said homogenous rock is encountered below the breakpoint, then the slope below the breakpoint shall be no steeper than two to one to the rock elevation, and no steeper than 0.5 to one from the rock elevation to ten feet below the control elevation. c. In the event that property where a commercial or exempt agricultural excavation was previously excavated is rezoned/developed for uses other than agriculture, the excavation shall be modified to the standards for development excavations in accordance with the requirements of section 22-112(b) llrsller, or other criteria as may be more stringent. 9 Words strack thrmlgh are deleted, words underlined are added. d. Exceptions to the side slope requirements that may be justified by such alternatives as artificial slope protection or vertical bulkheads shall be approved in advance by the site develollHleAt revie'", Engineeling Review Services Department Dairector, where justification shall be documented in a design analysis prepared by a professional engineer registered in the State of Florida. Bulkheads may be allowed for no more than 40 percent of the shoreline length. Exception to the breakpoint depth may be granted by the Engineering Services Department based on historical water elevation data. e. Reseryed. f,,,, No building construction permits will be issued for any proposed construction around the perimeter of any excavation where the minimum clearance between the excavation top-of-bank and the proposed building foundation is less than 30 feet, unless and until all side slopes adjacent to the proposed construction have been completed and approved by the county manager or designee. Exceptions to this requirement will be made in those instunces where the perimeter of the excavation will he bulkheaded in accordance with the provisions of section 22-l12(b)(4). (3) Depths. Unless site conditions, water quality or soil information indicates otherwise, the excavation depths as measured from the permitted control elevation shall be as follows: a. Maxi mum. Pri vate and development excavations shall not exceed 20 feet in depth unless computations using the "fetch formula" of maximum depth = 5 feet + (0.015) x (mean fetch in feet) indicate that deeper depths are feasihle. The mean fetch shall be computed as follows: (A+B)/2 where "A" is the average length parallel to the long axis of the excavation and "B" is the average width of the excavation as measured at right angles to the long axis. Commercial excavations shall not exceed 20 feet in depth unless otherwise supported by the "fetch formula," or if it can be shown from a comparative water quality study that depths in excess of 20 feet will not, because of aquifer conditions or relative location to coastal saline waters, have a detJimental effect on the groundwater resources in the surrounding area. b. Mil.imum. In order to assure that unsightly conditions or undesirable aquatic growth will not occur in wet retention areas during the dry season of the year, the bottom elevation of these excavations shall be at least six feet below dry season water table, unless the portion of the lake in Question is a littoral zone planting area. c. Over-excavation. In those instances where the excavator over-excavates the depth of the excavation by more than an average of ten percent, written justification shall be submitted to the county manager or designee by the project's surveyor/engineer providing an assessment of the impact of the over-excavation on the water quality of the excavation. If, upon review of the assessment statement by the county manager or designee and e!:;nvironmental aAdvisory eCouncil, the increased depth is found to be unacceptable, the permittee shall be required to fill the excavation to the permitted depth with materials and methods approved by the county manager or designee. If the depth is deemed acceptable by the county manager or designee and approved by the environmental advisory council, a penalty will be against the 10 Words struck through are deleted, words underlined are added. permittee for the volume of over-excavated material. The penalty shall be set by resolution for each additional cubic yard of excavated material. (4) Fencing. If, at any time, the county manager or designee finds that the location and conditions of an excavation are not in, or able to be brought into, compliance with all requirements of this article, the excavation shall be buffered with a minimum of a feHFsix- foot-high fence with-"No Trespassing" signs as deemed appropriate by the county manager or dcsignce to deter passage of persons. (5) flours or operation. Hours of equipment and blasting operations shall be regulated by appropriate county ordinance and state laws. Unless otherwise approved by the county manager or designee, all excavation operations with the exception of dewatering pumps, which are within 1,000 feet of developed residential property, shall be limited to operating hours hetween 7:00 a.m. and 5:00 p.m., Monday through Saturday. HOllrs of operation for private and for type I aHd type II commercial excavations located in Estates zoning districts shall be 7:00 a.m. to 5:00 p.m., Monday through Friday. Additionally, such excavation operations shall he in , compliance with any and all county ordinances which establish operating controls by hours, days, noise level, or other parameters relating to public health, safety and welfare. (6) Restoration. Upon completion of the excavation operation, the subject property shall be restored as required by the 1986 State of FIOlida Resource Extraction Reclamation Act (F.S. ch. 378, pt. IV). Reclamation shall mean the reasonable rehabilitation of the total disturbed area where the resource extraction has OCCUlTed, and shall meet the reclamation performance standards established by the state. All disturbed areas, including the excavation side slopes above the watcr line control elevation contour and a 20-foot wide area around the entire perimeter of the excavation, measured from the control elevation contour, shall be sodded or fertilized i!nd seeded with a quick-catch seed variety approved by the county manager or designee within 60 days of the final side slope shaping in order to minimize the potential for erosion. (7) Discontinuance of operations. If the excavating operation is inactive for a period of 90 consecutive days, except due to strikes or acts of God, all side slopes, including the working face, shall conform with this article and a report so stating, prepared and sealed by the project's surveyor/engineer shall be submitted to the county manager or designee. Recommencement shall also be reported to the county manager or designee. If the excavating operation is never started or if discontinued for a period of one year, that permit is void unless a wIitten request is made by the permittee with sufficient justification for a time extension in which case the county manager or designee may authorize a permit extension for up to 180 days. A new permit must be approved prior to commencement. (8) Non-water management system lakes. Non-water management system lakes of a surface area of one acre or less, may be riprapped along their entire shoreline under the following conditions: a. Side slopes shall be at a ffiiniffiHffi no steeper than a ratio of two to one. b. Littoral shelf areas mllst conform to section 3.05.10 of the WG.Land Development Code. 11 Words stmck tAroHgh are deleted, words underlined are added. c.
