HomeMy WebLinkAbout2006-193D R��rR f Utilities Services/Solid Waste Disposal District P� ( Departmental Structure and functions The Utilities Services Department employs a diverse staff of approximately 100 employees in the office and in the field . The Solid Waste Disposal District employs approximately fifty-one staff members , forty of which work in three field operating divisions . Y The Solid Waste Disposal District , organizationally, works under the Utilities Services Department . However, in terms of budget , this District is a separate entity . The major duties of the Solid Waste Disposal District include: environmental compliance , surface water sampling and analysis , permitting , commercial waste , and landfills . The Solid Waste Disposal District is divided into the following four divisions : Administration - ( Accounting, Engineering , and Office Staff) Three Operating Divisions (field personnel ) o Landfill Division Recycling Division Refuse Division y The Utilities Services Department consists of a merger of three distinct departments: Water System , Sewer System , and Solid Waste Management . The main responsibility of the Utilities Services Department is to ensure the public health and safety of the County ' s water supply . Three basic parts to the water supply include source , treatment , and distribution . Other responsibilities include : • Administration • Customer Service • Assessments • Engineering • Conservation • Water/ Wastewater Facilities Administration /Customer Service The Administration Office oversees all of the Departments, administers regulations , and ensures the smooth flow of operations . Management staff includes the following : Director of Utility Services Assistant Director of Utility Services Operations Manager • Manager of Capital Projects Supervisor of Customer Service and Billing Assessments The Board of County Commissioners may provide for local services or improvements to encompass : streets and roads , water and sewage systems , water and sewage treatment plants, drainage, street lighting , sidewalks , and such other services or facilities which may be deemed essential as determined by the Board of County Commissioners , based on special assessments that are issued through Indian River County ordinance number # 92-28 . This ordinance includes the following : requirements and form of petitions , publication and adoption of the services or improvements , preliminary assessment rolls and hearing , notice to owners of final assessment rolls , payment of assessments , assessments to become liens and providing authority to borrow funds . 136 GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessment Engineering and GIS Mapping The Engineering Division monitors and tracks county managed utility projects and tracks and issues permits for all private utility construction . The Division also ensures that all utility construction complies with Indian River County utility standards. Engineering staff also function as a hands-on design team and act as a private consulting firm to plan , design , and pilot research on technologies and in- house projects. These innovative practices allow the Engineering Division to more effectively manage the County ' s infrastructure through vision , innovative thinking , and team effort . The GIS Mapping Division maintains the County ' s GIS utility infrastructure and maintains a variety of maps and records . These include construction and as-built drawings, water and sewer base maps , customer complaints , work orders , accounting records and much more . At present, two GIS staff members assist the Utilities Services Department in all GIS related tasks . Conservation Conservation service is aimed at outreach programs and functions to aid citizens in reducing water bills and more effectively utilizing County water and sewer resources . This is accomplished through education via the County website . Recommendations are made on how citizens can lower their monthly water bill . Some of these suggestions include : Take showers rather than baths . • Replace showerhead with a water-efficient showerhead • Faucet aerators in kitchen and bath save 4% • Turn off water when brushing teeth or shaving (saves an average of 5 gallons a day) If you wash dishes by hand rinse them in a sink partially filled with water instead of running water • Use food scraps for compost or dispose of them in the garbage bin rather than the garbage disposal Wash full loads of cloths , a washing machine uses up to 35 gallons a load • Only run dishwasher when it is full Water/Wastewater Facilities The Utilities Services Department maintains several facilities throughout Indian River County to effectively manage water and wastewater treatment activities . These include : Aerating tanks, a North County reverse osmosis plant, a South County Reverse Osmosis Plant, and several water storage tanks . r The Department currently uses GIS for the storage of utility infrastructure and has copies of Arclnfo for use with floating licenses . Two staff members in the Engineering /GIS Mapping Division use GIS to create maps and maintain utility GIS data in an ArcGIS personal geodatabase format; at present these are Tier 2 and Tier 1 GIS Users . All remaining GIS users in the Utilities Services Department will be Tier 3 GIS Users ; ( see Chapter 2 : GIS Organizational Structure and Staffing for more information on tiers of GIS Users) . Additional opportunities exist for GIS utilization throughout the Department . It is expected that as the County proceeds with its GIS implementation , additional resources within the 137 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment Department will utilize GIS on a regular basis , and existing GIS users will acquire additional knowledge and access to applications that will enable them to function as Tier 2 GIS Users . Existing Hardware and Software At present , everyone in the department has a PC ; approximately thirty-three PCs and eight laptops are being utilized in the Department. All computers are running Windows XP or Windows 2000 operating systems and have access to the County network . The Department also utilizes a large format plotter to print maps. The Department uses the following software packages in various capacities . ' GIS Software 1 . Arclnfo 9 (3 licenses on the network) 2 . ArcView 9 ( 3 licenses being used on laptops for locators) 3. AutoCad Map 2005 Non - GIS Software 1 . MS Office Suite 2 . WaterCAD from HAESTAD Methods 3 . MUNIS ( Work Orders) 4 . Selfer - modeling software 5 . Waste Works Arclnfo 9 Arclnfo Is used extensively by Utilities GIS staff to maintain a variety of maps and records . " These include construction and as- built drawings , water and sewer base maps, customer a7 complaints , work orders , accounting records and more . °�--..

The Telecommunications Department utilizes one of these - - a licenses for GIS functions . ___-_. Arc ESRI 's Arclnfo // F3�1 . ! I /�YN 138 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment AutoCAD Map 2005 AutoCAD Map 2005 is utilized by the Utilities Services Department for site design and drafting in r support of facility infrastructure and maintenance projects . Although AutoCAD Map can be utilized for some GIS tasks , if is ' -TH 3_!4 � - { primarily an engineering and , design tool . The Department expects to continue to utilize this product in support of some of its utility infrastructure tasks and prOJeCtS . + , Autodesk AutoCAD MUNIS MUNIS software is utilized for a variety of mission critical functions . ' Various divisions within the Department utilize the software , primarily for MUNISwork orders . Important data about the County is stored in the MUNIS database . At present, there is no link between MUNIS software and GIS . Sharing data between MUNIS software and GIS can be quite cumbersome . Often , professional programming skills are required to select the appropriate data fields and to extract the data in a useable format . As the County implements additional GIS technologies , it is recommended that a streamlined data extraction and integration process should be established . Data will need to be downloaded to an accessible format, such as delimited ASCII file , for use in GIS or via direct connection to backend MUNIS database. There are some universal problems faced by users of comprehensive integrated local government applications such as MUNIS . The successful and robust usage of the data in many of the MUNIS modules is predicated on having good addresses or parcel identification numbers ( PINS ) . However, in almost all cases throughout the United States, address fields are not maintained or maintained poorly without any standards . One way that organizations deal with this problem is having a master street index that is integrated with the various software modules . This master list is utilized when adding addresses in any database . The user has to pick from a pre-defined list of accepted street names , suffixes , address ranges . etc . This ensures data consistency and integrity. It is recommended that Indian River County Computer Services staff work with GIS personnel in the Utilities Services Department to extract pertinent data from MUNIS on a set interval for use in GIS . Although direct connectivity to the MUNIS database is feasible, performance of 139 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment the system , as well as GIS applications , would be cumbersome and slow. Many companies , ' including MUNIS, are creating links to GIS and/ or creating GIS interfaces to their data ; an opportunity may exist in the future to utilize an integrated GIS interface ( once developed ) . Q" Recommended GIS Needs and Duties The Utilities Services Division has a great opportunity to integrate GIS to provide mapping support to the County as a whole . It is expected that the recommended GIS Director will provide the Department with GIS support for advanced tasks. Several options for GIS data creation and management are present, based on the recommended hybrid GIS organizational structure within the County ( see Chapter 2 : GIS Organizational Structure and Staffing for more information ) . GIS Needs for the Utilities Services Department include : • Conversion of Data from an Arbitrary Coordinate System • Utility Geodatabose Geometric Networks for Water and Sanitary Sewer Utilities • Water and Wastewater Modeling -- • GIS-Based Work Order Management System • Standards for Digital Submission of External Data • Data Production and Maintenance of Infrastructure Data • Automatic Vehicle Location ( AVL) • GIS-based Public Notification • Formal GIS training for Department staff Each of these needs is discussed fully below. A key opportunity for all departments within the County lies in centralization of GIS data and distribution of this data via several tiers of GIS applications . Utilities Services personnel will produce and maintain data that is critical for many of the various County Department ' s GIS needs . Working in tandem with the recommended GIS Director, the Department will yield many benefits and contribute to various successes during the County ' s continuing implementation of GIS and complementary technologies . If is recommended that the majority of Utilities Services Department personnel utilize an Intranet GIS data browser to conduct basic spatial analysis and produce maps . This Intranet browser will be based on the enterprise-wide Intranet GIS data browser recommended for the County . More information on the Intranet GIS data browser is provided in the Enterprise- Wide Applications section of this chapter. More sophisticated mapping and analysis will be conducted by the Engineering and GIS Mapping Division , which will use more sophisticated software , such as ArcGIS . PtConversion of Data from an Arbitrary Coordinate System At present, the Utilities Services Department maintains GIS utility infrastructure in an unknown , or arbitrary, coordinate system . This represents a significant hurdle for the county-wide implementation of GIS as many departments indicated a need to have full access to the utility GIS infrastructure for daily operations . As the County moves forward with its GIS implementation , the recommended GIS Director should work in cooperation with Utilities Services Department staff to ensure that all existing and future utility infrastructure data is represented in a valid coordinate system . Utilities Services staff expressed the need to convert existing Utility infrastructure GIS data into a State Plane Coordinate System so the data lines up with other County data and can be 140 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment viewed and analyzed simultaneously in a GIS data browser. This conversion of existing GIS data is known as a coordinate transformation . The Department has the option to outsource the coordinate transformation or perform all conversion in-house . Based on the scope of the project, current staffing within the Department and the intricacies of the service, it is recommended that this conversion be delegated to a qualified consulting firm . Please refer to Appendix VI : Coordinate Transformations for a list of items that should be considered as guidelines for the conversion of existing GIS data into a state plane coordinate system . A second option is to use GPS to capture the true field location of all above ground features (i .e . hydrants , manholes, lift stations , etc . ) . This would need to be contracted out to a qualified engineering firm . Utility staff could be used to connect the points and do attribution using as-builts . The Utility Department would work with the GIS Director in developing a data model that would be in the best interest of the Utility Department . IIS Utility Geodatabase Geometric Networks for Water and Sanity Sewer Utilities ESRI , in conjunction with many public and private utility organizations, has developed data models for water and sanitary sewer distribution networks . These data models are designed to create a logical template for the creation of water and sanitary sewer ArcGIS geodataboses . The advantages of utilizing these data models include : Utility business logic : rules for how utilities can and do interact ,. • Standardized template of utility features, feature attributes , and relationships ( fully customizable , however) • Utility specific symbology Network tracing tools - ability to conduct tasks on each network, including : trace upstream , trace downstream , find connected features , and more The following figure is a schematic of the full ArcGIS Water Distribution Data Model : ArcGIS Water Distribution Data Model 141 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment All of ESRI ' s ArcGIS data models, including Water Distribution and Sanitary Sewer can be downloaded for free from ESRI ' s website (www .esri .com ) . Data models can be downloaded in three different formats, including : GIF file, UML, or Repository . The GIF file is merely an image, to be used as an analysis diagram . The UML can be opened in MS Visio , to be modified using CASE tools . MS Visio Enterprise is required to be able to export the modified data model to an MS Repository database . The downloadable repository can be imported directly into ArcCatalog , to create a geodatabase . Data models can be modified in either MS Visio or ArcCatalog . One geodatabase can be created for all utility networks . Separate feature datasets should be created for water and sanitary sewer networks . The next step is to populate each feature dataset with utility data . Once each feature dataset is conflated , sources and sinks must be added to the network . Sources designate the origin of flow, and sinks designate the end of flow . The following figure represents a sanitary sewer network, created by Geographic Technologies Group for the City of Pearland , TX , displayed in ArcMap . Gravity mains are displayed in different shades according to pipe diameter. Force mains are displayed in red and blue . Lift stations and wastewater treatment plants are also displayed . Other features , such as manholes and cleanouts are available for display, but are not turned on in this example , because of the scale of the map .

By developing these models , Department staff will be able to use powerful network design , analysis , and modeling features available with ArcGIS 9 . Access to and use of the geodatabase is paramount to the successful integration of the y geodatabase into the Department ' s daily workflow. Many options exist for enterprise storage and retrieval of the water and sanitary sewer geodataboses . ESRI ' s spatial database engine ( ArcSDE) allows management and maintenance of the geodafabase in a commercially available relational database management system ( RDBMS ) such as Microsoft SQL Server . Database tools such as object permissions , data versioning , backup and recovery strategies can be leveraged to deliver a comprehensive data integration solution An enterprise solution using ESRI ' s ArcSDE is recommended for the County and the Department should use this platform to store its infrastructure data . 143 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment Version A Version B Version C ArcSDE data versioning allows for multiple data users Water Distribution Wastewater, and Storm Water Modeling and Monitoring ,. The Utilities Services Department can use GIS to conduct water and wastewater modeling . There was also a stated need in the Solid Waste Disposal District to perform stormwater modeling . A recommendation has been made in the Public Works Department Needs Assessment for the County to develop an accurate stormwater database ; once conversion is complete , this data can be utilized for stormwater modeling . Accurate modeling requires accurate utility data . ArcGIS will let Department staff perform basic modeling tasks . For example , assuming the sanitary sewer network was set up correctly, users could select a lift station , choose to perform a " trace upstream " task, and all structures that flow to that specific lift station would be selected . The Utilities Services Department currently maintains WaterCAD software from Haestad Methods . The Utilities Services Division should consider implementing Haestad Method ' s SewerGEMS and FlowMasfer applications for wastewater modeling and Haested Method ' s StormCAD , FlowMasfer, CulvertMaster, and PondPack for Storm Water modeling—these applications offer modeling that provides full , completely seamless integration with ArcGIS applications see GIS Applications below) . FlowMasfer Interface FlowMasfer Analysis and Design GIS- Based Work Order Management System The Solid Waste Disposal District indicated a need to transfer all paper based work orders to - a database and implementation of a GIS based work order system . The Utilities Services Department including Water and Sewer already uses MUNIS for work order management. If is 144 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment recommended that the Solid Waste Disposal District and Utilities Services Department coordinate with the recommended GIS Director to implement a GIS- based work order management system integrated with MUNIS . A critical component of successful Departmental GIS implementations is accurate and complete data . Maintenance crews and other field personnel will go out into the field and make changes or additions to the infrastructure and not report these changes back to GIS staff. Very quickly GIS layers are missing pertinent data or contain erroneous data . Users will not know what data is accurate and what is not . Therefore , data sets can become suspect and staff may begin to doubt its usefulness and reliability. The solution to this problem is a GIS-based work order management system . A properly implemented work order management system would allow staff to quickly input specific information about a task and then print out a paper work order with an accompanying « map . This map would show the infrastructure for the area of concern . Field crews would then mark any changes or additions to the system on the work order. Once the job was complete field crew would then return the work order with changes back to support staff for input into the work order management system and for update of appropriate data layers . An added benefit of such a system is continual fine-tuning and improvement of mapped ( GIS ) data . If any errors exist on the GIS maps, then field crew will mark and correct the error. In turn , this information will be corrected in the GIS . Therefore , instead of GIS data degrading because of information not flowing back from the field , GIS data will continually improve because of corrections made in the field . Subsequently, GIS data will reflect a very accurate depiction of the real world . In addition , there are residual benefits of such a system . Implementing a work order system will insure that this data is accurate and will facilitate rapid determination of assets in the field . There are several applications available to meet this need (see GIS Applications below ) . It is recommended that the Utilities Services Department implement an application that will easily integrate with existing information technology, including the County ' s various enterprise databases . A Tier 3 GIS product that links to work order applications can meet a basic need for production of a blank work order form and a corresponding map . A GIS work order extension for work order software is practicable if the selected enterprise work order software stores data in an open database such as MUNIS ( ODBC /OLEDB compliant) . This will allow use of a Tier 3 GIS application that can access data directly from the work order system . This application should allow users to quickly print out a map and a work order form for field crews to take into the field . It is critical that this application have the ability to track open work orders . Work orders that are not returned from the field will cause degradation in the GIS data . This must be avoided . Of Standards for Digital Submissions of External Data In some instances the Department receives outside information form surveyors and contract base resources . Externally produced maps range in quality, medium and global reference accuracy ; quality of these maps can range from hand-drawn sketches to digital maps from surveyors . Digital maps from surveyors sometimes lack global reference, including no coordinate system . As a result, GIS personnel may have difficulty importing this data and ascertaining its accuracy. 145 GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessment It is recommended that the Department establish a digital data submission protocol that specifies how data should be submitted , what information needs to be included with each submission , and resolution procedures . It is recommended that in the long term the Department work to implement the Federal Geo-Spatial Data Committee ( FGDC ) u Geospatial Positioning Accuracy Standards , Part 4 : Architecture , Engineering , Construction , and Facilities Management ( FGDC-STD-007 .4-2002) ; this standard is generally known as Part 4 of the FGDC ' s Geospatial Positioning Accuracy Standards . Part 4 provides accuracy standards for engineering drawings, maps , and surveys used to support planning , design , construction , operation , maintenance, and management of facilities, installations , structures, transportation systems , and related projects . It is intended to support geospatial mapping data used in various engineering documents , such as architectural , engineering , and construction ( A / E/ C ) drawings , site plans , regional master planning maps, and related GIS ) , Computer- Aided Drafting and Design ( CADD ) , and Automated Mapping/ Facility Management ( AM/ FM ) products . These products are typically created from terrestrial , satellite , acoustic , or aerial mapping techniques that output planimetric , topographic, hydrographic , or feature attribute data . The Part 4 standard defines accuracy criteria , accuracy testing methodology , and accuracy reporting criteria for object features depicted on A/ E/ C spatial data products and related control surveys . It references established voluntary standards that may be used for some f smaller-scale A / E/ C mapping applications . In addition , the standard contains general guidance for specifying accuracy criteria for selected types of A/ E/ C features or control surveys . Using the standards and guidance contained in this section , end users of A / E/ C M products ( e .g . , Utilities Services Department) can specify surveying and mapping accuracy requirements needed for their projects or specific CADD/GIS layers, levels , or entities . From these specifications , data producers ( e .g . , surveyors , engineering firms , consultants) can determine the instrumentation , procedures , and quality control processes required to obtain and verify the defined accuracies . By implementing this common standard , the Department will be able to maintain consistent documentation of construction designs/plans provided by external entities . This will facilitate the review and assessment process, and ensure that staff can interpret data consistently . It is recommended that the Utilities Services Department and the future GIS Director implement and enforce digital submission standards and guidelines . This effort will provide control and specifications for the submittal of digital data from contracted resources used in the construction of County infrastructure . An internal protocol must be set up to deal with external maps that do not conform to the digital submission standards . • Kf Data Production and Maintenance of Infrastructure Data The Department ' s relationship with the recommended GIS Director is crucial for the County ' s GIS implementation . Needs assessments for various departments/divisions throughout the County identified the interaction between the daily routines of the departments and the recording of infrastructure changes to the GIS through personnel in the Utilities Services Department . It is recommended that Utilities Services personnel , in particular GIS Mapping Section personnel , continue to produce and maintain the County ' s water and sanitary sewer infrastructure map data , working in close cooperation with the recommended GIS Director to address any data design or data acquisition issues . It is also recommended that the Utilities Services Department and GIS Director work with personnel in the Public Works 146 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment Department to document and archive all relevant information about the County ' s infrastructure—this is a much needed effort that will need to be addressed as priority in order to ensure long term success for infrastructure mapping and analysis . Once complete and accurate water and sanitary sewer networks are created , it should become the responsibility of the GIS Technician in Utilities Services to maintain these datasets. This will require that the Utilities Services Department provide him with information „ regarding any modifications to infrastructure , including new development or changes to existing infrastructure . It is recommended that the infrastructure data that is generated reside in the recommended County wide Enterprise GIS database offering . This platform will allow for a rich environment for the editing and viewing of GIS data and flexibility for versioning and concurrent multi-user access . Other critical data layers that will need to be created and maintained by the Utilities Services GIS Mapping Section , in addition to GIS augmentation use , include the following : ,. • Solid waste collection boundaries Solid waste facilities • GIS layer depicting recycling bins • Location maps with reports on flow directions • Permitting and environmental compliance • Complaint mapping Redistricting maps • water and Sewer customer locations Proposed project information • Track maintenance records - for budget purposes Automated Vehicle Location fAVL ) The Utilities Services Department has expressed an interest in implementing AVL technology for its vehicles . This will allow Utilities Services personnel to track the location of all vehicles of the fleet , in order to improve response time and monitor the location of vehicles in case of an emergency . Implementing AVL can be very expensive . Therefore , the Utilities Services Department should coordinate with other potential AVL users ( Sheriff and Fire Department ) to potentially purchase one system that can work for all County vehicles . The department should use AVL in conjunction with existing mobile computing equipment to ensure that this information can be viewed in data browsers in the field as well as in operations offices . " e Public Access to Geo-Spatial Data The Utilities Services Department expressed a desire to participate in the county wide internet mapping application . At present, an internet mapping application is being used in the _- Property Appraiser ' s Office to disseminate information to the public . However, there was a stated need to migrate to a different application since the current one is quite weak on custom queries . Consequently , an alternate solution is being considered . The Internet browser should have the ability to incorporate data from the various departments as opposed to tax data alone . The Utilities Services Department can provide information for a mapping application that will enable citizens to view and analyze utility and infrastructure availability information . Typically organizations will allow for controlled publication of their infrastructure information to assist 147 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment the public in accessing information about utility services and availability in a certain area . Often this information is vital to business and citizens interested in new construction and feasibility of system construction . Providing this data to the public could assist in the economic development and attractiveness of the County to the development of new business and construction . This effort should be coordinated with other departments in the County that manage complementary data . As part of the County ' s objective to migrate to a more robust Internet GIS data browser, the Department should coordinate with the recommended GIS Director to integrate departmental GIS data into the Internet-based application . The Department should identify additional functionality that may be required in addition to the County ' s base enterprise offering . A formal review and assessment process should be established prior to making any information available , as some data may be sensitive or confidential . Reviews should be coordinated with the recommended GIS Director and approved by Utilities Services and County Attorney to ensure that no sensitive or confidential data is distributed publicly. s.,.., a,.et. • s Im s+..+ii � J �Ed,...,.l. 01 1 cbvvvo _ . c m��� ,. . , .

NtGIS- Based Mass Notification System for Emergencies and Maintenance There is a need for a GIS- based public notification solution . It is recommended that the Department leverage the GIS- Based Mass Notification System that the County plans to implement as a tool for notifying the public about maintenance, outages , and emergencies . See the Sheriff ' s Office Needs Assessment for more information on GIS-Based Mass Notification System applications . Nt Formal GIS Training for Department Staff Several departments/divisions , including the Utilities Services Department , will benefit from formal training in GIS . It is recommended that the Utilities Services Department and the recommended GIS Director identify key department staff to receive formal training . As some data will be moved to a geo-spatial format, it will become increasingly important to ensure that staff has the required knowledge and skills to modify and maintain data in a GIS environment . More information on training opportunities can be found in Chapter 8 : GIS Training and Education . 148 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment iiGIS Data Layer Inventory and Recommendations The Utilities Services Department will benefit from access to several other departmental GIS data layers . It is expected that once all departmental data is integrated , consolidated , and centrally stored , that staff will have access to all non-classified GIS data layers from other County departments . Utilities Services personnel expressed that access to the following GIS data layers would be beneficial : Extract, cleanse , geocode , and map from address database; georeference Automated ; Community Address Points based on aerial Development/Planning Recommended photography and GPS field work Aerial Photography Fly-over with control points GIS Data Services Vendor Existing Digitize from base map Base Lines data ; existing CADD data ; Property Appraiser - GIS Existing aggregate layers as and Mapping needed Bicycle/ Pedestrian Digitize from base map Engineering Facilities data ; GPS field work Division/Surveying and Recommended Mapping Digitize polygons from aerial Property Appraiser - GIS Building Footprints photographs and existing and Mapping Existing maps ; existingCAD data pp g Extract , cleanse , geocode Building Permits and map from CD- Plus Automated Recommended database Buildings with Site Manually digitize polygons Engineering Plans from plans and address Division/Surveying and Recommended sources Mapping City Limits Acquire from Ordinance Property Appraiser - GIS Existing Information and Mapping Acquire using Contour Lines photogrommetric GIS Data Services Vendor Recommended techniques County Limits Acquire from Ordinance Property Appraiser - GIS Existing Information and Mapping Easements Derived from aerial Property Appraiser Existing photography; GPS field work Digitize from aerial Encroachment photography and base GIS Director Recommended " ma Environmental Acquire from Ordinance Community Compliance Information , existing hard Development/ Environ men Existing u copy maps tal Planning 149 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment Extract , cleanse, geocode Groundwater wells and map from database GIS Director Recommended TBD Digitize from aerial Hydrography photography and base GIS Director Existing N ma Digitize polygons from aerial Land Use photographs and existing Community Development Existing maps; existingCAD data Maintenance Extract, cleanse , geocode, Records and map from existing Utilities Services Recommended database Acquired from tax records ; Property Appraiser - GIS Parcels Cogo and MappingExisting Digitize from base map Parks data ; aggregate layers as GIS Director Recommended needed Extract, cleanse , geocode Permitting and map from CD- Plus Automated Recommended database Railroads Derived from aerial GIS Director Existing photography: GPS field work Extract , cleanse , geocode Recycling Bins and map from database Utilities Services Recommended TBD w Digitize from base map data ; aerial photography; Engineering Division/ Land Right- of-way Recommended aggregate layers as Acquisition needed Digitize from base map Engineering Schools data ; GPS field work Division /Surveying and Recommended a Mapping Sewer Base Map Digitize on screen ; existing Utilities Services Existing /Arbitrary data ; GPS field work Coord .

A detailed description of each of the recommended applications , where applicable , is provided in the Enterprise-wide application section later in this chapter. The table located below is an application functionality matrix which describes the GIS functionalities recommended for the department and should be considered while reading about the individual application requirements as described later in this section . The following is a list of the recommended GIS applications : Internet GIS Data Browser An improved county wide Internet GIS data browser has been recommended to provide citizens with access to the County ' s geo-spatial data . The Property Appraiser currently has an Internet application that is being used to host GIS data ; however, a more sophisticated browser that handles custom queries is being investigated . In addition , the county wide browser should have the ability to incorporate data from the various departments as opposed to tax data alone . A description of recommended GIS data browser solutions is provided in the Enterprise-wide Applications section of this chapter. Intranet GIS Browser An Intranet GIS data browser has been recommended for use by Utilities Services personnel . This application will serve the entire county but will have a specific configuration for Utilities Services personnel .

To effectively achieve its objectives, The Department consists of five main divisions, including : • Tangible (or personal ) Property ' a Real Property • Assessment Control GIS and Mapping • IT Key responsibilities of the Property Appraiser include producing a tax roll and property assessments . Tax parcels for the county are maintained in an ESRI Geodatabase and are maintained and updated regularly . Another important role is to establish a value for all property for tax purposes . The Assessor is required by law to set the property value and to assure that all values are in equalization . The mission of the Property Appraiser is to maintain an equitable, fair, and uniform system to all citizens of Indian River County . At the some time , the Property Appraiser must meet all w constitutional and statutory requirements and provide an optimal level of service , information and policy guidance to the public and to other governmental agencies . M A parcel layer and other associated layers are maintained by a GIS Mapping Coordinator and four GIS mappers in a SDE geodatabase storage format . The parcels layer is crucial for a successful Countywide GIS implementation effort . As the County moves forward with its GIS implementation , various spatial and non-spatial information managed by the Property Appraiser, will become increasingly integral to helping the County achieve its technology goals . The majority of GIS users in the Property Appraiser will be Tier 3 GIS Users ; however, some GIS use within the Department will involve more complex mapping and analysis, such as that of Tier 1 and Tier 2 GIS Users . Tier 1 GIS application use is already demonstrated by the GIS Mapping Coordinator and GIS Mappers . ( See Chapter 2: GIS Organizational Structure and Staffing for more information on Tier 1 , Tier 2 & Tier 3 GIS Users ) . "JgExisting Hardware and Software At present, approximately 50 PCs are being used by Office staff. There are also ten laptops for use by field appraisers . All computers are running Windows XP or Windows 2000 operating systems and have access to the County network .

The current process of transferring permit data to the A- Plus CAMA system involves printing paper permits and manually inputting data into CAMA . There was a stated need to improve this process via a direct read of the CD-Plus permit table in an Oracle RDBMS . A key opportunity exists for a county wide integration of the CD- Plus database with both standalone and Intranet GIS data browsers .

NET, or CGI Recommended GIS Needs and Duties Property Assessor ' s Offices throughout the country have implemented GIS in varying capacities—Indian River County ' s Office of the Property Appraiser is well positioned to implement GIS in a highly sophisticated capacity and to complement existing GIS activities within the Office . Based on this needs assessment, the Property Appraiser' s Office has several GIS needs , including : • Centralized GIS Environment • Base Mapping • Mapping and Spatial Analysis to Assist in Property Assessment Operations • Public access to Geo-Spatial Data ' m Centralized GIS Environment It is recommended that the Property Appraiser ' s Office continue to use ESRI ' s ArcGIS b platform for the majority of its data storage, query, modeling , and map generation needs . ArcGIS will be implemented as the central GIS platform throughout Indian River County . Working from the same GIS platform will greatly simplify data sharing and access for both the Property Appraiser' s Office and other County departments . A full description of ArcGIS and its components is included in the Enterprise-Wide Applications section of this chapter. One of the primary recommendations for the County is the centralization of the geo-spatial data into an enterprise geodatabases . Existing infrastructure , as well as an existing working relationships among various county departments , should be leveraged to establish this shared geodatabases . In addition , this effort will provide an opportunity to develop shared , consistent data standards for the County as well as cities within its jurisdiction . A centralized GIS Environment will provide the following benefits : • Maintain all geo-spatial data for Countywide departments in an enterprise -. geodatabase environment for maximum sharing and improved editing workflows 163 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment • Provide all County Departments centralized access to critical base map information such as streets , tax parcels , aerial photography, and address points • Increased cost sharing between departments and maximized data sharing capabilities • Have access to current layers maintained by other departments throughout the county Property Appraiser staff indicated that access to the following layers would be beneficial : • Utilities Parks • Building permits • Site plans as they are submitted (instead of waiting for emails ) • Land use and zoning (instead of importing shapefiles) Address information ( county-wide address point layer) In addition , providing access to a centralized enterprise geodatabase will allow street centerlines to be shared in a more efficient manner. At present, Emergency Services updates and maintains the streets while many other departments use copies of the data set for their particular purposes . This inefficient method prohibits much of the necessary data sharing that is possible through a centralized GIS server. For example , the Property Appraiser currently uses a copy of the street centerline layer and adjusts it spatially to fit with the parcel base for map labeling and display purposes ; two problems result from this process , first, consumption of time to manually move streets, and second , continually working with outdated street centerlines as new streets are added regularly. Base Maopina The Property Appraiser ' s Office is tasked with the maintenance of the parcel layer, and over time has developed an adequate tax parcel dataset, although spatial accuracy seems to be an issue . As aforementioned , the parcel boundary layer is a critical GIS base map layer from which additional layers are derived and referenced across multiple departments within the County . As a result, the Property Appraiser ' s Office plays an important role in maintaining one of the key datasets for the County ' s GIS initiative . At present, the GIS Mapping Coordinator and GIS Mapper' s in the Office maintain and update the parcel layer in an ArcGIS SDE geodatabase . ArcGIS is being used to make edits to the parcel feature class as new plats and subdivisions are submitted . New parcel numbers are assigned to the data set as new features are created . At present, attribute information within the parcel layer, to include parcel number, tax code, use code , owner name, site address , and sales code among others , is very accurate and up-to-date . However, as previously noted , the spatial accuracy of the layer is an issue that needs to be addressed . The GIS Mapping Coordinator indicated that a base map enhancement project is currently being pursued by the County Surveyor. The Property Appraiser' s Office should work in close coordination with the recommended GIS Director to ensure that the parcel layer' s spatial accuracy is improved over time as a result of the enhancement project . This effort will provide the County with a very accurate base parcel map over which all other GIS data sets can be overlain . Another key consideration to be made in regards to the parcel layer is the planned conversion to a new CAMA system . Staff indicated that no modifications to the existing geodatabase will occur until this transition is complete . As aforementioned , the transition 164 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment may affect workflows and geodatabase schema within ArcSDE . It is recommended that Property Appraiser personnel work closely with the recommended GIS director to ensure a smooth transition and make certain all possible scenarios are considered . For more information regarding the Parcel layer refer to Chapter 4 Base Map Creation and Considerations . RtMapping and Spatial Analysis to Assist in Property Assessment Operations GIS applications can be used by the Property Appraiser' s Office to conduct the following types of analysis : Assessment Ratio Studies • Overlay Analysis • Locating Comparable Properties • Adjacency Analysis • Calculating Land Use Percentages • Evaluating Properties • Field Access to data for Property Appraisal The Assessor' s Office has two options for conducting these types of property appraisal analysis . 1 . Office staff can utilize an intranet GIS data browser that provides a pre-configured and easy to navigate user-interface to conduct simple analysis for property appraisal . 2. For advanced analysis the Office can work with the GIS Mapping Coordinator and the recommended County GIS Director, who can use advanced GIS software such as ArcGIS to conduct many Tier 1 GIS tasks . Although the existing AccuGlobe Interactive Record Search and GIS Mapping System is a very good tool , it is designed to display and query primarily property information . It is also limited in terms of custom queries . In order to eliminate costly and time consuming paper map production , it is recommended that Indian River County implement an Intranet GIS Data Browser enterprise-wide . This tool will allow all County employees to access a wide-variety of County spatial data layers, with powerful yet easy-to-use functionality. Please refer to the Enterprise-Wide Applications section of this Needs Assessment Chapter for more information on an Intranet GIS Data Browser. INtPublic Access to Geo-Spatial Data The Property Appraiser ' s Office expressed the need to disseminate spatial information to the public by providing a mapping application that will enable the County ' s citizens to view and analyze property information . As aforementioned , the AccuGlobe Mapping Application is being used to disseminate information to the public . However, there was a stated need to migrate to a different application since the current one is not sufficient in regards to custom queries . Consequently, an alternate solution , CAMA WEB Online Tool from STI (Software Techniques Incorporated ) is being considered . The Internet browser should have the ability to incorporate data from the various departments as opposed to tax data alone . The mapping application should incorporate the ability for the public to view property information , including an interface that will allow citizens to navigate to the Property Appraiser ' s Office website for additional information . This effort should be coordinated with other departments in the County that manage complementary data . 165 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment As part of the County ' s objective to migrate to a more robust Internet GIS data browser, the " Department should coordinate with the recommended GIS Director to integrate departmental GIS data into the Internet-based application . The Department should identify additional functionality that may be required in addition to the County ' s base enterprise offering . In addition to an Internet GIS data browser, the Office will benefit from the implementation of a touch screen public kiosk system that will provide an easy-to-use interface while saving valuable staff time and resources .

QCose Study : Web- Based Property Assessment System Implemented with GIS 1 For forward-thinking government entities like the County of Los AngelesAssessor's Office , a revolution is taking place . Agencies are 2i leveraging the Internet to serve constituents with valuable information about their communities and at the same time saving = money, time, and resources . It 's simply . . . . government operating at maximum efficiency . A key part of this revolution involves Internet GIS . - The Los Angeles County Assessor's Office is + one branch of the County's Property 166 GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessment Taxation System . Other branches include the Offices of the Registrar- Recorder, Auditor- Controller, and Treasurer-Tax Collector. The Assessor's responsibilities include serving the public , locating and identifying ownership, establishing values, completing an assessment roll , and applying all legal exemptions . Under the County Assessor's Office is the Assessor's • Mapping Services Section . For decades , the ownership and property tax data sets were recorded on thousands of paper maps . These maps span Los Angeles County, which is the most populous county in the nation and is larger in population than 42 states in the United States . Los Angeles County's approximately 9 .9 million residents live within its 4,083 square miles , making it one of the largest counties in terms of area as well . In the past, property and tax maps were only ' available to citizens who visited the Assessor's offices and made requests for hard-copy information . The Assessor's Mapping Services Section began automating its map- making and editing efforts with GIS in the late 1980s . Through the years, the organization grew and matured as a GIS site, and in 1997, Mapping Services acquired ArclMS with the goal of providing data more easily to the public via the Internet. "We wanted to provide a service to constituents that made parcel and property value information available so y - that they, in turn , could make informed decisions ," says Richard N . Quacquarini , chief cadastral engineer, Office of Los Angeles County Assessor's Mapping Services Section . "We wanted something that was intuitive and very user friendly and provided the targeted functionality whether a user has a slower dial-up • connection or a faster broadband + connection : ' Also integral to their two system configurations are ArcGIS , ArcSDE, and ArcView 3 .2 ; one ' system is on-site providing production needs , and the other is off-site providing Web applications . The Assessor's system is called the Property Assessment Information System ( PAIS) . Users access PAIS through a standard Web browser to research assessment information - for individual parcels , print Assessor's maps , ` and search for sales within the past two ears . Users can o0 y pan and zoom and view indexed parcel information including property values, parcel numbers , sales data , and more . Whether running a query based on a parcel number, address , or street . . . intersection or merely panning and .. zooming around a map , users can quickly access linked Assessor's information via 167 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment digital maps on the Web . The Assessor contracted ESRI to help in the development of PAIS , which includes data from Rand McNally's Thomas Bros . Maps and the County Department of Public Works and a link to the Treasurer-Tax Collector's Web page . "The Web site lets a real estate agent select a subject property and then buffer out 500 and 1 ,000 feet or one-fourth , one-half, and one mile to identify all properties that have sold in the past two years , ' says Steve Trammell , ESRI cadastral solutions manager. " Real estate professionals account for a significant amount of the public service counter traffic because they are looking to establish acceptable buying and selling prices on a property." According to Trammell , a real estate agent can identify comparable properties (with similar square footage, bedrooms , and baths) to determine a baseline selling price . These professionals would normally have to telephone the Assessor's Office or visit the Registrar- Recorder's Office to get this kind of information . PAIS features a seamless GIS parcel map base with links to scanned versions of the actual hard-copy assessment maps. The response time on the 2.3 million parcel GIS database is very quick, and users can quickly link to a scanned map for legal description information and lot dimensions . "It 's an example of true public access with ArclMS providing the technology architecture for access to very detailed map data ," adds Trammell . "This is a very successful site and represents a huge savings in public counter labor costs ." " In October 2001 , there were four million page views with 1 . 4 million map requests .

It is expected that once all departmental data is integrated , consolidated , and centrally stored , that staff will have access to all non-classified GIS data layers from other County departments . Property Appraiser' s Office personnel expressed that access to the following GIS data layers would be beneficial : Extract, cleanse, geocode, and map from address + Address Points database : georeference Automated : Community Recommended based on aerial Development/ Planning photography and GPS field work Aerial Photography Fly-over with control points GIS Data Services Vendor Existing Digitize from base map Property y Appraiser Base Lines data : existing CADD data : ppn - GIS Existing aggregate la ers and Mapping 168 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment Bicycle/Pedestrian Digitize from base map Engineering Facilities data ; GPS field work Division /Surveying and Recommended Mapping Buidling Footprints Digitize polygons from aerial Property Appraiser photographs and existing and Mapping Existing ma s; existing CAD data Extract, cleanse, geocode Building Permits and map from CD-Plus Automated Recommended database Buildings with Site Manually digitize polygons Engineering Plans from plans and address Division /Surveying and Recommended sources Mapping City Limits Acquire from Ordinance Property Appraiser - GIS Existing Information and Mapping g Acquire using Contour Lines photogrammetric GIS Data Services Vendor Recommended techniques County Limits Acquire from Ordinance Property Appraiser - GIS Existing Information and Mapping g Easements Derived from aerial Property photography ; GPS field work p Y A ppraiser Existing Hydrography Geocoded/ Digitize GIS Director Existing Digitize polygons from aerial Land Useexistin hoto ra hs and Emergency Services or = p g st g Planning Existing maps; existingCAD data Parcels Acquired from tax records ; Property Appraiser - GIS Co o and Mapping Existing Digitize from base map Parks data ; aggregate layers as GIS Director Recommended needed Extract, cleanse , geocode Permitting and map from CD- Plus Automated Recommended database Railroads Derived from aerial photography; GPS field work GIS Director Existing Digitize from base map Right- of- way data ; aerial photography ; Engineering Division /Land g y aggregate layers as Acquisition Recommended needed Digitize from base map Engineering Schools data ; GPS field work Division/Surveying and Recommended Ma in Streams Derived from aerial GIS Director Existing - hoto ra h ; GPS field work Street Centerlines Derived from aerial GIS Director Existing photography; GPS field work 169 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment Digitize from base map Subdivisions data ; acquire from Community Recommended ' developers submitting Development/ Planning proposed develo ment GPS field work; convert from Engineering Survey Control CAD Division /Surveying and Recommended Mapping Tax Districts Digitize from base map Property data; GPS field work P Y Appraiser Existing Township, Range Property Appraiser - GIS and Section lines Digitize from measurements and Mapping Existing Urban Service Areas Query from parcel layer; other sources as needed Community Development Existing Utilities Data Digitize on screen ; existing CAD data ; GPS field work Utilities Services Existing Digitize polygons from aerial Water Bodies photographs and existing GIS Director Existing maps ZoningDigitize from base map Community data ; extract from parcels Development/ PlanningExisting ""= Recommended GIS Applications To meet the Property Appraiser' s Office GIS goals the following GIS software is recommended . A detailed description of each of the recommended applications , where applicable , is provided in the Enterprise-wide application section later in this chapter. .j Internet GIS Data Browser ' An improved county wide Internet GIS data browser has been recommended to provide citizens with access to the County ' s geo-spatial data . The current internet mapping application , Accu Globe Internet by Digital Data Technologies ( DDTI ) , lacks some desired mapping functionality. Since the Office indicated a need for more robust functionality, especially in terms of custom queries , the Office will need to work with the recommended GIS Director to organize the development of an enterprise-wide Internet GIS data browser to provide the public with access to geo-spatial data including the parcels layer. The Internet browser should have the ability to incorporate data from the various departments as opposed to tax data alone . A description of recommended GIS data browser solutions is provided in the Enterprise-wide Applications section of this chapter. Public Kiosk Data Browser A public kiosk data browser has been recommended for the Property Appraiser' s Office to give citizens access to County-wide geo-spatial data when they visit the physical offices of the Property Appraiser. A description of recommended GIS public kiosk data browser solutions is provided in the Enterprise-wide Applications section of this chapter. Intranet GIS Data Browser An Intranet GIS data browser has been recommended for use by Assessor' s Office personnel . The Intranet GIS data browser should provide property appraisal mapping functionality for all Office personnel . This application will serve as the primary enterprise-wide GIS application 170 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment for the Office .
