DOWL has assumed collection at each site from Late April to Mid-October collecting flow depth readings every 15 minutes. Project Management • DOWL will perform general project management tasks including setting up the contract, invoicing and coordinating with the City of Bozeman. Assessment of Flow Measurement Sites • DOWL will perform a preliminary evaluation of the various south-to-north drainage to access which drainages to install flow measurement devices. Nine drainages will be initially reviewed and it's assumed that 3 to 5 drainages will be recommended for flow measurement. o Take pictures of locations potential locations. o Collect general drainage ditch dimensions. o Assess high water marks and baseflow conditions. • DOWL will coordinate with the City of Bozman on the recommendation of the drainages to be measured. Flow measurement devices may be installed at multiple locations along a drainage to understand contributing runoff developed areas of the City. Flow Measurement Program • DOWL will travel to the site and set up the flow depth measurement equipment. o Survey a cross-section of the ditch and channel flowline points upstream and downstream to estimate the slope of the ditch. o Install the In-Situ flow piezometer at the edge of the channel banks and verify the elevation it is set at. o Take pictures of the cross-section at setup. • DOWL has assumed the City of Bozeman will participate in one of the site set ups and initial flow measurement collection for some internal in-the-field training. DOWL will step through the flow measurement equipment,set up and program the equipment, and step through flow measurement collection using the HACH flow meter. • Process data and develop a preliminary rating curve for each cross-section using some estimated values. • DOWL will travel to the site and use a Hach meter to determine the current flow rate at the site. Three actual measurements will be performed at each site. o Take pictures of the ditch at the time of flow measurement. o DOWL may download the collected depth data from the In-Situ piezometer depending on the setup conditions. o Use flow measurement value to calibrate the cross-section rating table. DocuSign Envelope ID:02DA0807-F2D7-4F2D-80EE-D1E8EBB2EA75 • DOWL will travel to the site and tear down the equipment at the end of the collection period. • Develop final deliverables, GIS map of the flow measurement sites,flow rate chart for each site and an excel document with all the collected flow data and photos. Cost Estimate $32,000
