EXHIBIT "A" <br /> SCOPE OF SERVICES <br /> Consultant shall provide wastewater flow monitoring services as part of the City's annual flow <br /> monitoring program as described in more detail below. Services shall be provided at the seven <br /> (7) sites listed below. <br /> TASK 1— Perform fleld reconnaissance and document review <br /> Consultant shall review pfans and documents and conduct field reconnaissance of the <br /> proposed flow monitoring sites identified by the City. The reconnaissance shall <br /> assess hydraulic conditions, manhole access, traffic control requirements, and safety <br /> issues for each site. No modifications to the proposed meter sites shall be made <br /> without prior review and approval by the City. <br /> Deliverable: Consultant shall submit documentation of site reconnaissance <br /> and final flow monitoring sites to the City by November 15, 2011. <br /> TASK 2— Installation / Calibration / Maintenance / Removal of Flow Monitors <br /> Consultant shall install seven (7) flow meters and one rain gauge for a period of sixty <br /> (60) days starting no later than December 3, 2011, with an option to extend the <br /> monitoring on a weekly basis up to one additional month. The flow meters will be <br /> area-velocity type capable of ineasuring flows and flow depths under surcharge <br /> conditions. Pipe diameters will range from approximately 8 to 15 inches. Rain <br /> gauges will be tipping bucket type capable of recording to 0.01 inch. The flow <br /> monitoring locations are as follow: <br /> 1. Junipero Avenue near Roosevelt Avenue (15") <br /> 2. 385 Main Street (Sewer behind easement) (15°) <br /> 3. Hess Road near Geneva Avenue (1 5") <br /> 4. Poplar Avenue near Ebener Street (12") <br /> 5. Jefferson Avenue near Middlefield Road (10") <br /> 6. Hopkins Avenue near EI Camino Real (15") <br /> 7. Commercial Way near Perry Street (6") <br /> The flow meters and rain gauges shall be installed at the approved sites and visited <br /> weekly during the monitoring period. Consultant shall report to the City within 24 <br /> hours of each site visit if any meter malfunctions, or otherwise fails to provide good <br /> data, or if changes in site conditions have impacted collection of good data. Field <br /> calibration data (independent measurements of flow depth and velocity) shall be <br /> collected throughout the monitoring period for each meter to verify monitor accuracy <br /> over a range of flow depths. The flow monitoring data will be collected at 5-minute <br /> intervals and reported at 15-minute intervals. The meters will be interrogated at each <br /> site visit and the data (conside�ed preliminary) will be provided to the City for review <br /> on a weekly basis within three (3) days after interrogation. At the City's discretion, the <br /> data submittals may be reduced to a biweekly basis after the first two (2) weeks if the <br /> initial data appears to be good. The final data shall be compiled following removal of <br /> the flow meters and rain gauges. In the event that more than one (1) flow meter fails <br /> ATfYlAGR/2011.126N&A 38000 Page 9 of 10 <br /> REV: 11/14111 <br />
