iii. Sheet C3.0—Permeable pavement should be constructed in accordance with City of Everett Standard Drawing 430 and 431 and the applicable sections of the DCSS. The permeable pavement has been revised to be constructed per City of Everett Standards. See sheet 3.0 iv. Sheet C3.0—Permeable Pavement Section—Clarify what"subgrade, determined compaction based on design requirements"means. How is the contractor to interpret this statement?Also, should the existing subgrade be scarified,tilled, or otherwise treated to promote infiltration since it was previously under conventional pavement or building areas? Note #8 has been revised to clarify that the subgrade should be scarified if the soil is too compacted. v. Sheet C3.0—Include the standard drainage note per DCSS Section 4-2.7. The standard drainage notes have been added. See sheet C3.0 vi. Sheet C3.2—This sheet does not show pavement types. If it is intended as documentation of surfacing for stormwater requirements please label it as such and provide a paving plan. As the set is currently put together it is unclear how the contractor and inspectors will determine which paving sections are to be placed where. The permeable pavement especially needs to be more clearly identified beyond the light dotted pattern on sheet C3.0. The sheet has been renamed to "Stormwater Requirements Exabit". The paving plan is incorporated into C3.0. The permeable pavement hatch has been revised to be more clearly identified. See revised plan sheets. Please feel free to contact me with any questions or comments you may have.
