Five Mile Slough Outfall Improvement Project (Lake or Streambed Alteration Agreement No. 1600-2016-0172-R2)

Five Mile Slough Outfall Improvement Project (Lake or Streambed Alteration Agreement No. 1600-2016-0172-R2)

CDFW has executed Lake and Streambed Alteration Agreement No. 1600-2016-0172-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, City of Stockton Public Works Department. Project is limited to improvements at the outfall at Five Mile Slough where it is crossed by Pershing Avenue. Five Mile Slough flows below Pershing Avenue through a dual box culvert 5 feet high by 10 feet wide. The proposed improvements include upgrading the existing 15-inch diameter outfall pipe to a 42 inch diameter pipe. The location where the existing outfall empties into the box culvert will be enlarged to accommodate the new pipe size. A new outfall location will not be created. The majority of the work necessary to install the new pipe will take place from the road above, outside Five Mile Slough. It is anticipated that coffer dams will be installed at both ends of the north barrel, diverting the water through the south barrel, so work can be conducted on the wall opening. Access to the slough is narrow, and therefore it is anticipated that heavy equipment will operate from the road, not from areas within the slough.
