the remaining portion of"SMLD5"just south of the Carnegie Building connection. Laterals"SMLD3", "SMLD7"and"SMLD 10", beginning at manhole"SMHD3" at the west edge of Oakes and extending east through manhole"SMHD7"and manhole"SMHD10"in the east-west alley south of the Work Release Building and terminating at manhole"SMHD 12"at the west edge of Lombard, must be removed. These laterals serve the Administration Building, the parking garage, and surrounding courtyards. Relocation may take several routes. Service must be maintained during relocation of the lateral and during demolition of the parking garage. Lateral SMLD12 from SMHD 12 to SMHD 15, serving portions of the campus. routes combined sewer flows under the Everett Senior Center at the northeast corner of Pacific Avenue and Lombard Avenue. The City Public Works Department wishes to abandon this line. Public Works has instructed that combined sewage flows to this line be redirected north to discharge into the existing combined sewer at the intersection of Wall Street and Lombard Avenue. Lateral "SMLD23" from "SMHD23"to Wall Street must be removed for construction of the new parking garage. Additionally, most of the private storm drains and sanitary sewer services on the campus would require removal and relocation as a result of new construction. Any lateral requiring relocation must be sized to accommodate peak combined sewer flows. Construction for relocating laterals "SMLD3", "SMLD7" and "SMLD 10"would require closure of Oakes Avenue and Wall Street. Construction time is estimated to be about 7 weeks. In addition, construction would require closure of Lombard between Pacific and Wall for up to 6 weeks. Portions of the roadway may be reopened as work proceeds by providing temporary paving and patching. It should be noted that a City combined sewer lateral located in the vacated alley west of the Mission Building passes under the Courthouse. This lateral conveys flow from offsite areas to the south in addition to serving the Mission and Courthouse buildings. No new building development is currently planned along this lateral;however, any future plans should consider impacts of this lateral. Water The new main in Oakes must connect back into the City's system, either via a crossing at Pacific, or via a new 8-inch line running west or east along the north side of Pacific to Rockefeller or Lombard. The existing 6-inch main extending south across Pacific is an old, cast-iron pipe, which may or may not be adequate depending upon the condition of the existing main and the extent of disturbance and/or damage,which may result from replacing the main to the north. Drainage Conveyance of the storm-water from the site must meet City Standards.With regards to the retaining walls for the parking garage in particular,drainage must be provided so that water pressure cannot build up behind any walls. Detailed drainage plans for each stage of development must be reviewed and approved by the City prior to issuance of construction permits for that development stage.
