<br />i. Alrlngton Road near Woodstock Place (8") <br />ii. Claremont Avenue near EI Camino Real (8") <br />iii. Industrial Way near "C" Street (10") <br />iv. End of Alden Street (15") <br />v. Clinton Street near Vera Avenue (10") <br />vi. Palm Avenue near Oxford Street (10") <br />vii. Hudson Street near Palm Avenue (10") <br /> <br />V&A wlll be responsible for taking all necessary safety precautions in the performance of the work, <br />followlng all applicable Federal, State, and local regulations for working in confined spaces, and <br />complying wlth all applicable traffic control requirements of the City or other agencies with jurisdiction <br />over the meter sites. <br /> <br />The flow meters and rain gauges will be Installed at the approved sites and visited weekly during the <br />monitoring period. V&A shall report to the City or City's master plan consultant within 24 hours of <br />each site visit If any meter has malfunctioned or failed to provide good data, or if changes in site <br />conditions have Impacted collection of good data. Field calibration data (independent measurements <br />of flow depth and velocity) will be collected throughout the monitoring period for each meter to verify <br />monitor accuracy over a range of flow depths. The monitor data will be collected at 5-minute intervals <br />and reported at 15-minute Intervals. The meters will be interrogated at each site visit and the data <br />(considered preliminary) will be provided to the City or City's master plan consultant for review on a <br />weekly basis within 3 days after interrogation (at the City's discretion, the data submittals may be <br />reduced to a biweekly basis after the first 2 weeks if the initial data appears to be good). The final <br />data will be compiled following removal of the flow meters and rain gauges. In the event that more <br />than one flow meter fails to provide usable data during a significant storm event (> 0.5 inches of <br />rainfall In 24 hours), V&A will extend the monitoring period for up to 2 weeks at no additional cost to <br />the City. <br /> <br />3. Deliverables: V&A will submit a Flow Monitoring Report (3 copies) containing site details and pictures; <br />field installation and maintenance sheets including calibration data; depth-velocity scatter plots; 7-day <br />plots of flow for each meter and rainfall for each rain gauge; and summary tabulation of daily average, <br />minimum. and peak flow for each flow meter. Electronic files will be submitted in Excel format <br />containing depth, velocity, and flow rates for each meter and rainfall for each rain gauge in 15-minute <br />intervals. Final report and data shall be delivered within 3 weeks of completion of flow monitoring. <br /> <br />We propose to complete this work on a time and materials basis as follows: <br /> <br />7 Flow Meters and 1 Rain Gauge for 60 days: <br />Weekly Extensions of Flow Meters and Rafn Gauge: <br /> <br />$32,500 <br />$3,500 per week <br /> <br />Terms are Net 30 days and this price Is valid for 90 days from the date of this proposal. The scope of work <br />was developed as a result of our discussion and represents our mutual understanding. Estimated costs for <br />the above project scope are itemized in the attached Resource Allocation Estimate. These costs represent <br />our best estimates at this time and may change subject to future developments during the project. It is <br />possible that some of the estimated manpower requirements for specific task items may increase while <br />others may not require the enUre anticipated effort. This provides us a greater degree of confidence in the <br />overall project estimate, rather than in any given particular task. <br /> <br />:iV&A <br />
