- M Chapter 926: Landscape and Buffer Regulations 43. Section 43: [amends 926.07(2)(b)4.] corrects a typographical error. Chapter 927: Tree Protection and Land Clearing 44. Section 44: [amends 927.08] amends the county's mangrove trimming regulations to parallel, conform to, and reference state requirements. With this amendment, no conflicts should exist between county and state mangrove trimming regulations. Chapter 930• Stormwater Management and Flood Protection *45. Section 45: [amends 930.07(1)(f)] provides for the use of flap -gate riser stormwater devices, as currently allowed by county policy, in determining the appropriate elevation of an outlet device in relation to a receiving channel or water body. 46. Section 46: [amends 930.07(1)(1)1.] sets a minimum diameter of 12" for single family driveway culverts. *47 Section 47: [amends 930.07(1)(m)] revises and relaxes some stormwater tract and Swale sloping requirements as well as making some clarification changes in that subsection. 48. Section 48: [amends 930.05(3)] makes it illegal, unless otherwise permitted by the county, to discharge fluid from a swimming pool, washing machine, water circulation heat pump, or other mechanical device into a stormwater management system. This change was initiated by Public Works staff to address drainage problems associated with the discharge of water, other than stormwater run-off, into drainage systems that are not designed to handle the extra water/fluid. The proposed regulation would be retroactive, applying to existing homes. Public Works staff have indicated that this regulation would be enforced through code enforcement action, initiated via drainage complaints. 49. Section 49: [amends 930.07(2)(d)] restructures a section of the stormwater chapter to clarify floodplain cut and fill requirements. The changes also relax the cut and fill lot size exemption threshold from j to 1 acre. Finally, a cut and fill balance exemption is added for the large Blue Cypress Lake floodplain area due to the unique characteristics of that floodplain. In the opinion of the County engineer, the result of this additional exemption will not adversely impact stormwater management within the Blue Cypress Lake, floodplain area. Note: at its November 5, 1991 regular meeting, the Board discussed an emergency item related to this section which requires cut and fill balancing on certain sized single family lots in flood plains. As of the date of this report, no additional staff or Professional Services Advisory Committee input can be provided. However, by the time of the November 20th meeting, staff will present additional information, and input from the Planning Services Advisory Committee. Chapter 931: Wellfield and Aquifer Protection 50. Section 50: [amends 931 introductory table of contents] expands a subsection topic heading to better reflect the contents of the subsection. **51.Section 51: [amends 931.09] adds language from the Comprehensive Plan, which parallels water management district regulations, restricting the use of Floridan aquifer artesian wells. r1a POOK 64 uGEj
