Project Information and Background2013Cost Estimate YearProblem Summary:Overloaded sanitary sewers due to wet weather flows.Solution Summary:Construct approximately 2,850 feet of 12-inch sanitary sewer and appurtenances.Model Summary:The downstream four reaches are part of the Buckhurst Drive HYDRA lateral. The 10-year HGL is above the ground in this section.General Discussion(Discussion of pertinent aspects not elsewhere addressed (potential constructability issues, right of way concerns, background info from other sources, modifications(s) from original scope, permit considerations, utility conflicts, special features, etc.).)No history of complaints, but since the sewer is located in/near a tree covered creek bed, surcharging and OMHs may go un-noticed. Several reaches crossing the creek currently have open work orders to be lined, which could greatly reduce the amount of wet weather flows in the system. Recommend flow monitoring after lining work is completed.Priority Points:17Tier Designation:Tier 2Does Project remove CSO-SSO:If yes, List ref.
