6502 EVERGREEN WAY ENHANCED SERVICE FACILITIES 2020-01-21

• PUBLIC WORKS c. Sheet C-2: See redlines. Update TESC Legend and adjust line work to correctly show TESC elements and remove site improvements from this sheet. d. Sheet C-3: Update City of Everett Standards to match current names and standard drawing numbers in the DCSS. See redlines. e. Sheet C-4: See redlined notes regarding re-use of existing 3/4 water meter. f. Sheet C-5: See redlines. A fire hydrant, FDC, and PIV need to be added to the plans on the Fleming Street side of the project. On the Evergreen Way side of the project, the domestic water service needs to be sized adequately for the demand of the proposed project. The existing 3/4" service can be reused for irrigation only, with the addition of a DCVA behind the meter. The domestic water service should be larger (your engineers to determine what size). The City will make the connection to the main. Please add these notes to the plans. An RPBA is required behind the domestic meter and shall be located in a hot box since the service line is greater than 70' long. g. Sheet C-7: Call out and label curbing wherever planned. At the end points it is best to call out BC and TC elevations. The contour lines drawn do not match typical grading associated with curbs based on how the contours travel over the curbs. In some cases, particularly near the ramp into the parking garage, the contour lines travel over the curb in opposite directions. This grading error has made a 1' elevation error on the parking garage ramp and needs to be corrected. I would suggest starting at the grade needed to meet parking garage finish floor elevation and grading out from there. This could in turn affect the conveyance system on-site, as the rim elevations may need to change and that may affect the inverts if the required rim to invert distance is not met due to surface grading revisions. Please carefully update this entire system and a complete review will be conducted upon resubmittal. h. Sheet C-8: The profile shows utility crossings for power and the roof leader. Please call out the clearances between these utilities and the storm conveyance system. The required vertical and horizontal clearances must be met for these utilities. i. Sheet C-9: See all redlines. The contours on the frontage improvement need to be revised to ensure a cross slope no greater than 2% to meet ADA requirements. The existing (surveyed) spot elevations or contours should be shown to ensure that the curb height is adequate and aligns with the sidewalk grading design. Please remove the truncated domes shown on either side of the driveway and correctly show the driveway on the plans to meet the details of Standard Detail #315. Spot grades should be added to the driveway to ensure constructability as designed and that grading aligns with designed ramp grades. There was a previous issue with the frontage improvements due to existing locations of poles and other equipment. How have these issues been addressed? I want to ensure that the issue has been adequately taken care of or designed around rather than Page 2 of 5
