6.A. - Page 45 of 6§r <br />Aareement for rueFoint Services Exhibit D — Water Budget Methodology <br />2. An alert shall be sent to a list of email recipients when either CIMIS or WU report a quality flag <br />associated with the data. The alert shall include an explanation of the quality flag and simple <br />instructions on what if any actions shall be taken by the user. <br />3. An alert shall be sent to a list of email recipients when an authorized user manually enters an <br />ETo or precip value. <br />4. There shall be an option to receive an alert sent to a list of email recipients when budget <br />formula calculations and processes have finished successfully or with errors. In the event of an <br />error the system shall provide details in the alert to assist the users in determining and <br />correcting the error. <br />5. An alert shall be sent if the turf value of NIR, calculated from weather data, exceeds NIRHist(m) <br />+ (NIRMax(m) - NIRHist(m) * 100), where NIRHist(m) is the historical average value for that <br />month and NIRMax(m) is the historical maximum value for that month. For example, if the <br />threshold is 100%, then an alert message will be sent whenever the calculated turf value of NIR <br />exceeds the maximum value for that month. If the threshold is 0%, then an alert message will be <br />sent whenever the calculated value exceeds the historical average value for the month. If the <br />threshold is 25%, then a message will be sent if the calculated value exceeds the historical <br />average value for the month plus 25% of the difference between the historical maximum and <br />the average values for the month. The current threshold is 100%. <br />Budget Modeling <br />At times Redwood City may need to calculate a water budget for our customers that does not affect <br />billing or any routine operations of the water budgeting process. This is to assist customers by providing <br />alternative budget estimates based on changes in Water Use Factors, or calculate a budget using a <br />different budget formula. In some cases this functionality will be used to correct calculation errors for <br />budgets used for billing and to manually adjust a customer's bill. <br />1. The system shall provide a budget modeling tool for use by City staff. <br />2. Inputs: The tool shall have an option to import WUFs from an existing subsite by entering an <br />account or subsite identifier or by searching customer name or service address. Inputs include: <br />a. Water Use Factors values (number entry) <br />i. Turf Area (ft) <br />ii. Non -Turf Area (W) <br />iii. Water Feature Area (ft2) <br />iv. Turf Efficiency (factor i.e. 0.5) <br />v. Special Needs (gal/day) <br />b. Water Use Type (dropdown menu) <br />c. Budget formula to use for calculation (dropdown menu) <br />d. Duration of calculation (two options) <br />i. Billing Cycle <br />1. Dropdown Menu <br />2. Output in daily budget <br />fl. Annual <br />REV: 04-23-19 PR <br />1.
