Backfill for all embankments, non-supportive and unpaved <br /> areas will be compacted to at least 90% of the maximum density based on the modified <br /> proctor test (ASTM D-1557) in 6-inch lifts, except trench fill and fill beneath roads will <br /> be compacted to 95% of the maximum density based on the modified proctor test (ASTM <br /> D-1557). <br /> 2.2.5 Erosion Control <br /> During project construction, erosion and sediment control measures will be implemented <br /> by the Contractor to prevent sediment-laden runoff from leaving the site. An Erosion and <br /> Sediment Control Plan will be developed in conjunction with the Stormwater Management <br /> Plan developed for the construction phase of the project. The plan will include the <br /> incorporation of silt fencing, straw bale dikes, storm inlet protection, swales, piping, and <br /> other measures to promote sediment and erosion control. <br /> 2.2.6 Stormwater Management <br /> A Stormwater Management Plan will be developed for the final stabilized site. The intent <br /> of the stormwater management plan will be to preserve the existing pre-development <br /> drainage patterns to the extent possible. The plan will include a stormwater collection <br /> system consisting of all or some of the following elements: detention/retention pond, <br /> swales, ditches, culverts, catch basins, and piping. <br /> 2.2.7 Roads and Parking <br /> Asphalt site roads and parking will be provided for access, operation and maintenance as <br /> shown on the Site General Arrangement drawing. Alternative access, if required by local <br /> regulations, will be provided as shown on the General Arrangement drawing. <br /> 2.2.8 Site Area Paving <br /> Areas within the power block will be surfaced with concrete or gravel as shown on the <br /> General Arrangement drawing. All roads will be paved with asphalt unless specifically <br /> shown otherwise on the General Arrangement drawing. Asphalt will be a minimum of 4 <br /> inches thick and will be placed in no less than 2 lifts. A minimum of 6 inches of 1.5 inch <br /> clean, uniformly graded, crushed stone over a geotextile fabric will be used in areas so <br /> designated on the General Arrangement drawing. Local conditions may warrant the <br /> crushed stone layer to be thicker than 6", but in no case will it be greater than 10 <br /> inches. Concrete aprons shown in the crane lift areas of the combustion turbines will be <br /> designed to support the crane loads during maintenance activities. <br /> Site roads will be provided that conform to the following: <br /> • Operating speed of 10 miles per hour. <br /> • Minimum road width of 20 feet, with 2-foot shoulders. <br /> Lodi Energy Center 3.2-3 LEC AFC <br /> 071608 Rev.A <br />
