Status: UPDATED occasionally using ArcMap

Contact: Michael Liberti, Tucson Water, 520-837-2226, Michael.Liberti@tucsonaz.gov

Intended Use: Primary data record of service area boundaries. Not intended for map display unless approved by data owner.

Known errors/qualifications This is a rough approximation of the obligated areas served by Tucson Water and some errors may exist especially in those areas outside the City of Tucson limits. Does not include the non-potable service area boundaries. The non-potable water system includes all water types that have not been treated to potable standards: reclaimed water lines, raw CAP mains from the canal, secondary effluent piped from the County treatment plant to the Roger Road reclaimed plan, TARP water in the mains between the recovery wells and the treatment plant and the CAVSARP recovery wellfields. Boundaries may overlap other water company service area boundaries because their definition of the boundaries may vary.

***SERVED = The parcel has a TW water meter and is consuming water.

***OBLIGATED = Either 1) a vacant parcel inside the City of Tucson that does not have a TW meter, or 2) a vacant/abandoned parcel that has a meter, but is not consuming water.

***COMMITTED = a parcel outside the City of Tucson that 1) is in an area of intergovernmental contractual agreement (e.g. Dove Mountain/Continental Ranch...) 2) is a master planned development for which TW previously granted a service agreement (will have a corresponding GREENLINE feature) 3) is under 20 acres and is located adjacent to a delivery pipe and is served on three sides 4) a Tucson Unified School District parcel

***NOT OBLIGATED = Call Tucson Water Development Services for clarification.

ALSO NOTE THAT PIPELINE RIGHT-OF-WAYS OUTSIDE TUCSON ARE ALSO COMMITTED (NO PARCEL) So, a parcel can be committed by contract, by prior approval or by location Individuals that live outside Tucson who are not currently served by TW fall under #3. Unless directed otherwise by Tucson Water, by default any parcel outside the City of Tucson that does not have a Tucson Water meter will NOT be served unless they annex.

Replaces ObligatedServiceArea feature class formerly maintained in VMDB. The name ObligatedServiceArea is still used, but now is just a filtered view of ServiceArea.

September 2010 - loaded ServiceArea shapefile into EDITSDE geodatabase to be maintained as feature class instead of shapefile. Renamed to ServiceArea. ObligatedServiceArea becomes a view of the ServiceArea feature class. sdetable -o create_view -T OBLIGATEDSERVICEAREA -t SERVICEAREA -w "SA_TYPE in ('SERVED','OBLIGATED','COMMITTED')" -c "OBJECTID,SHAPE,SA_TYPE,SA_SUBTYPE,REC_DATE,INSTALLYEAR" -i sde:sqlserver:pw-sql2005 -D editsde

August 2010 - ObligatedServiceArea criteria is redefined based on decisions by Mayor and Council. New shapefile called ServiceArea becomes the data of record.

10/10/2008 Bryn Enright Copy of most recent Obligated Service Area provided to John Regan from Pima County to post in the GIS Library and MapGuide site.

10/10/2008 Bryn Enright Renamed the feature class from admin.ObligatedServiceArea to admin.ObligatedServiceAreaHistory. The most current area will be made available in a new database view called admin.ObligatedServiceArea.

10/10/2008 Bryn Enright "Appended the most recent obligated service area created by Michael Liberti which was created by:

1. Dissolving the current service area (req_SA_current.shp) with committed areas outside the city (dove mtn, larry's marana, diamond bell, corona de tucson...)

2. Erased the city polygon (LIMJURIS) from the dissolve.

3. Added the entire city polygon back in (i.e. obligated area) but then erased all of the ""water providers"" with CCNs ('56' water right)." In = req_SA_obligated.shp Out = ADMIN.ObligatedServiceArea

June 2008 Bryn Enright Shapefile imported into Geodatabase (EMAPDB) In = Req_ServiceArea_v1.shp Out = ObligatedServiceArea

June 2008 Michael Liberti Layer dissolved to show only 1 polygon for obligated area. In = ServiceArea_v1.shp Out = Req_ServiceArea_v1.shp

June 2008 Michael Liberti Layer updated with new services and existing remote services that were not previously included.

February 2008 Michael Liberti Layer updated with new services for the 2008 Update to the Water Plan 2000-2050

November 2004 Michael Liberti "Modified PCLIS WATERCOS as collection of PARCELS intersecting SERVICES by M Liberti. Layer created for use in the Water Plan 2000-2050" In=PCLIS WATERCOS Out=ServiceArea_v1.shp
