<br />location of the customer's building complex (e.g. house, garage, etc.), and all associated land. It <br />is generally one parcel. For MFR customers, a site is the location of the building complex and all <br />associated land. For Comm customers, a site is all of the buildings to which the customer <br />supplies water at a location, and all associated land. <br />Water is allocated to a site, not to an account, meter, or customer. However water consumption <br />is measured at a meter, and billed to an account that represents that meter. This misalignment <br />creates issues in dealing with allocations that must be resolved. <br />1. City of Redwood City currently communicates with its water customers at the level of <br />the account1 (if summary billing applies, then several accounts may be aggregated <br />on one bill). Since accounts are not currently grouped to a site, new mechanisms for <br />communicating allocation information must be developed. This would apply to <br />informational messages (e.g. advisory messages about allocations or comparisons <br />of consumption and allocation) and possibly penalty bills when consumption exceeds <br />allocation. <br /> <br />2. Site allocation will be calculated based on site-wide factors such as landscape area, <br />number of occupants, etc. Allocations will apply to a 3D-day or 50-day period2, <br />depending on the billing period of the designated primary account at the site. <br />However, it is possible that a site may have accounts with different billing periods <br />and with different billing dates. If this occurs, comparing allocation to consumption <br />will be difficult. A remedy to this problem would be to require that all accounts at a <br />site have the same billing period and date. <br /> <br />3. A proposed allocation factor for Comm customers is Business Type. However it is <br />conceivable that many different businesses could be located at a site, and Business <br />Type must apply to the entire site. <br /> <br />4. If penalties are imposed based on consumption exceeding allocation, a formula will <br />be needed to calculate the penalties. Because allocation applies to the site, it will be <br />impossible to prorate excess consumption to the meter. Hence a site-wide rate <br />penalty structure will be required. <br /> <br />This requirement to redesign the data model provides an opportunity to improve significantly the <br />linkage with UBS, Redwood City's Utility Billing System. Rather than importing account updates <br />monthly from UBS as it currently does, the WAP database will link to the newly available <br />UtilityBilis SOL database that contains current account data for all utility customers. In order to <br />support the new data model, both the UBS and the UtilityBilis database will have to be <br />enhanced. <br />The following tasks will be performed to implement the new data model: <br />. Redesign the data model to support the customer - site - account - meter relationship. <br />Some of this work must be performed by Redwood City IT. <br /> <br />. Modify all processing relating to managing allocation factors to accommodate MFR and <br />Comm customers. <br /> <br />1 Landscape Water Use Reports prepared by BMP 5 Services are sent to some Comm customers. They <br />describe water consumption and water budget for a site. <br />2 To be exact, billing periods run from a given day of one month to the same day of the next month (if <br />monthly) or 2 months out (if bimonthly). Thus the number of days in a billing period is a function of the <br />number of days in the current and next month. <br /> <br />Agreement over $10K <br />City Attorney Approved Version 111803 <br /> <br />11 <br />
