<br />Contact utility service providers for field location of services 72 hours prior to beginning grading.
<br />Refer to the Geotechnical Report prepared by American Engineering Testing, Dated 09/14/22, for additional information on backfill
<br />material and groundwater conditions.
<br />Remove topsoil from grading areas and stockpile sufficient quantity for reuse. Materials may be mined from landscape areas for use
<br />on site and replaced with excess organic material with prior Owner approval.
<br />Remove surface and ground water from excavations. Provide initial lifts of stable foundation material if exposed soils are wet and
<br />unstable.
<br />Rough grade Building Pad to 12 Inches below Finished Floor Elevation (FFE).
<br />Refer to Structural Specifications for earthwork requirements for building pads.
<br />An Independent Testing Firm shall verify the removal of organic and unsuitable soils, soil correction, and compaction and provide
<br />periodic reports to the Owner.
<br />Place and compact fill using lift thicknesses matched to soil type and compaction equipment to obtain specified compaction
<br />throughout the lift.
<br />Compact cohesive soils in paved areas to 95% of maximum dry density, Standard Proctor (ASTM D698) except the top 3 feet which
<br />shall be compacted to 100%. Compact to 98% density where fill depth exceeds 10 feet. The soils shall be within 3% of optimum
<br />moisture content. In granular soils all portions of the embankment shall be compacted to not less than 95% of Modified Proctor
<br />Density (ASTM D1557).
<br />Coordinate with Architectural for building stoop locations. Slopes shown on adjacent walks and pavements should continue over
<br />stoops.

<br />nstall perimeter sediment controls prior to beginning work and maintain for duration of construction. Remove controls after areas
<br />contributing runoff are permanently stabilized and dispose of off site.
<br />Install inlet protection: Wimco RD or CG models as appropriate, or approved equal. Maintain protection until project is stabilized.
<br />Limit soil disturbance to the grading limits shown. Schedule operations to minimize length of exposure of disturbed areas.
<br />Management practices shown are the minimum requirement. Install and maintain additional controls as work proceeds to prevent
<br />erosion and control sediment carried by wind or water.
<br />Refer to SWPPP Notes on Sheet C3.4 for additional requirements.
<br />Reserved.
<br />Contractor shall prevent sediment laden water from entering the filtration / infiltration system until the site is completely stabilized.
<br />Stabilization must be started immediately to limit soil erosion when the construction activity in that portion of the site has temporarily
<br />or permanently ceased and will not resume for 14 calendar days.

<br />INFILTRATION BASIN INFORMATION & TESTING
<br />Avoid soil compaction of infiltration practices. Any equipment used in infiltration areas should be small scaled and tracked. Install
<br />protective fencing as shown before work begins
<br />The bottom of surface infiltration basins (not underground) shall be scarified to a depth of 12" prior to placement of topsoil or planting
<br />media.
<br />DESIGN PERMEABILITY RATES:
<br />Infiltration 1 was designed with a permeability of 0.45 inches/hour.
<br />TESTING:
<br />Infiltration Basins: At the time of basin excavation, and prior to placement of any material (soil, chambers, etc.), permeability testing
<br />shall be performed.
<br />Filtration Basins: Once filtration basin media has been placed, permeability testing shall be performed.
<br />Contractor shall engage a qualified testing firm to measure the permeability of the basin surface utilizing a Double Ring Infiltrometer,
<br />Modified Philip Dunn (MPD) Infiltrometer, or other method approved by the Civil Engineer or Geotechnical Engineer. Test results
<br />shall be greater than or equal to the following rates to meet long term rates required for design:
<br />Infiltration 1 needs a permeability of 0.9 inches/hour. - - DESIGNER: TESTED RATE SHALL BE TWICE REQ'D.
