Prior to scheduling the <br />project for consideration by the Planning & Zoning Commission, the applicant <br />shall respond to each comment in writing. <br />(4) Traffic and Nuisance Mitigation <br />(a) The noise and nuisance requirements of Chapter 974 shall be satisfied. Normal <br />operation of vehicles shall be deemed to meet Chapter 974 requirements. <br />1. Pumps, crushers, and processing equipment (including portable equipment <br />but not including vehicles) used on site shall be placed behind berms, located <br />below surrounding ground level, or equipped with mufflers (e.g. "turbo -style' <br />mufflers) or similar devices that significantly reduce the level of emitted noise. <br />(b) Dust/particulates and material spillage shall be controlled in accordance with the <br />approved project comprehensive dust and spillage control plan. <br />(c) Material stockpiles shall not exceed a height of 25 feet above the grade of the adjacent <br />project site perimeter. <br />(d) For purposes of these mining regulations, "haul route" shall mean the roadway <br />segment(s) traveled by haul truck traffic from the mining site to the nearest paved <br />major road intersection(s). The project haul route(s) shall be determined by the <br />Public Works director or his designee as a result of the traffic impact methodology <br />meeting with Public Works/Traffic Engineering. <br />(e) Unpaved haul routes shall be improved and maintained to the following standards: <br />1. Minimum gradable base of twelve (12) inches of suitable road base material <br />(material that can meet the compaction standard below) shall be provided for <br />the duration of the mining project. The mining operator(s) shall add gradable <br />base material as directed by the Public Works Director or his designee to meet <br />this gradable base material standard. <br />2. Base material shall be suitably compacted to meet LBR (load bearing ratio) 40 <br />standards. <br />3. The minimum gradable haul route width shall be 24 feet. <br />4. Where unpaved haul routes or haul route segments are allowed and the <br />anticipated project haul truck traffic from the proposed mine and approved <br />mines sharing the same haul route segment(s) exceed an average of 500 truck <br />trip ends per day las defined in section (4)0) below', the unpaved haul route <br />segment(s) shall be improved and maintained to the following standards: <br />a. Minimum sub -base of twelve (12) inches and twelve (12) inches of <br />suitable road base material (material such as coquina or structural <br />equivalent approved by the Public Works Director or his designee that <br />can meet the compaction standard below) shall be provided for the <br />duration of the mining project. <br />b. Road material shall be suitably compacted to meet LBR (load bearing <br />ratio) 1.00 standards. <br />c. The minimum gradable haul route width shall be 24 feet. <br />Double_Underline Text: Non Workshop Changes <br />Bold Underline: Additions to Ordinance <br />Ste-ke-through+ Deleted Text from Existing Ordinance <br />F:AComnumity Development \Users\CurDevAORDINANCE\2008\2008- <br />934 Excavation(afterl2-I9-08).RTF <br />12 <br />
