2.7 CLARIFICATIONS A. The purpose of videoing sewer laterals is mainly to determine the location of each lateral and determine if laterals are in conflict with the storm drain pipe that will be installed (See Project Notes 17, 18 on 9th Street Dwg No. G-04 and General Note 17 on Downs Drive Dwg No. G-04). The video of sewer mains needs to include at a minimum the following: a. Location of sewer laterals (distance along sewer main that can easily be coordinated with project drawings. Mark location of each lateral on curb or edge of pavement and provide an approximate depth of each lateral at the location of the proposed storm drain pipe (Project Note 17 on Dwg G-04). b. Identify material type of sewer lateral (i.e. PVC, transite) c. Provide video to City. The video needs to be in a format that the City can use and needs to provide a clear view of the sewer lateral pipes so that the City can inspect the condition of laterals.
