Water System Model, City of Lawrenceville, Georgia, 2006
Keck & Wood developed a model of the City’s potable water distribution system using MWH Soft’s InfoWater and ESRI’s ArcGIS Software. We used data acquired from the City’s and Gwinnett County’s GIS departments as a beginning point for building the model. Keck & Wood’s GIS and engineering staff integrated and updated this information as needed in order to build the model.
We analyzed all lines 6 inch or greater in size except where specific areas of interest were identified by the City. Minor, small diameter pipelines were consolidated in the modeling for simplification where no influence on the conclusions would be expected. We used Fire Department hydrant flow data and selective flow testing to provide reasonable confidence in the model’s calibration.
Once the model was built, Keck & Wood made multiple runs to analyze several “what-if” scenarios and simulation conditions. An extended time simulation was used to evaluate the impact of the daily tank filling and drawing-down cycle on system hydraulics. Keck & Wood met with City staff after the model was developed to discuss preliminary observations. We then made additional simulations suggested by the City to further explore new issues that may be identified in the preliminary runs.

GPS Locate Water Meters, City of Gainesville Public Utilities, Georgia 2005
This project entailed locating over 41,000 meters in the City’s water system covering most of Hall County for integration into their existing GIS. At the time of location each meter was attributed with the customer account number. This allowed the data to be linked to the billing information for that specific customer.
Keck & Wood is used GIS/mapping grade GPS for this project. We collected locations with a positional accuracy of plus or minus one meter in the field through the use of real-time correction with Coast Guard Beacon or Omnistar Satellite. That allowed our field crews to see immediately how well the data they are collecting will fit the existing information. This ensured a high level of quality. Keck & Wood’s crews were able to locate 95% of all meters in each route on the first pass with many routes coming in at 97% and 98%. This far exceeded our clients expectations.
Stormwater Inventory and Mapping, City of Palmetto, Georgia, 2006
K&W located and performed a detailed inspection of all publicly owned stormwater facilities within the City of Palmetto. The structures were located with sub-meter GPS. The condition of each structure, the size and materials of structures and conduits, inverts, a sketch of the location and a digital picture were all collected at the time of location. This data was then integrated into the City’s existing GIS database.
K&W also provides on-going GIS data maintenance and development services to the City of Palmetto. This includes maintaining the following maps Zoning, Water System, Sanitary Sewer, Land Use, and other specialty maps as requested.
Stormwater System Mapping, City of Ringgold, Georgia, 2005
Keck & Wood located all publicly owned stormwater facilities within the City of Ringgold. The structures were located using positions indicated on color aerial orthophotography. Prior to the flight, the City of Ringgold had marked the location of various utility structures on the ground so that they would be visible from the air. These locations were integrated into the City’s existing map data to produce both a composite map and an 11x17 map booklet.
MS4 NPDES Permit & Stormwater Utility Development, Union City, Georgia, 2006
Keck & Wood, Inc. assisted the City in preparation of its original MS4 NPDES Stormwater Permit Application. Once the permit was approved by the State, we developed a Stormwater Management Plan for the City. This was also submitted to and approved by the state. As part of these efforts, Keck & Wood conducted a field inventory of the Stormwater structures located in Union City. This inventory consisted of GPS locating the structures and collecting attribute information including structure type, condition, material, size, depths and a digital picture. The inventory data was then integrated in to the City’s GIS database. Keck & Wood also prepares the Annual Stormwater Report for the City.
Keck & Wood is currently assisting the City with the creation of a Stormwater Utility.
East Cherokee Drive & Waters Road Intersection Improvements, Cherokee County Georgia, 2007
A rural intersection required a slightly different method to solve a sight distance problem. The line of sight for the northern approach to a 3 leg intersection was limited due to a crest in the road profile. Rather than reconstruct the roadway’s approach, the county requested the design to separate the right and left turning turning vehicles from the through traffic. The intersection improvements were also coordinated with the construction of new residential street across and offset from the existing intersection. The project was designed for maintenance of traffic during construction without use of detours, installation of storm drainage without impact to existing water and gas lines and the extension of an eight-inch gravity sanitary sewer line utilizing a jack and bore steel casing under East Cherokee Drive. Concrete curb and gutter and longitudinal drainage systems were also added to both sides of East Cherokee Drive to reduce right of way impacts. Design complete in February 2007. Construction Cost $400,000.
Arnold Mill Road & Neese Road Intersection Improvements, Woodstock Georgia
A local 3-leg street intersection in Woodstock Georgia had an extremely skewed angle alignment. Traffic volumes on both streets continued to increase, which made entering the intersection from the side street very difficult and dangerous. The project objective was to improve the skew, add turn lanes and a traffic signal. The newly constructed roadway consists of concrete curb and gutter, sidewalks, guardrail and drainage systems. Project constructed to state standards and partially funded with state aid from the Georgia Department of Transportation. Construction completed in August 2007. Cost $700,000.

GIS Data Conversion & Custom software development, Austell Natural Gas, Georgia
Austell Natural Gas System is the third largest in Georgia. Due to its size, a full set of system maps stood almost eight feet tall making it impossible for field personal to carry a complete set of maps. Field crews were constantly returning to the main office to swap out map booklets. This resulted in many lost man hours and money for the Gas System. Keck & Wood fixed this problem by converting the existing gas system map digital data to ESRI’s shapefile format and developing a custom map viewing software package for crews to use in the field.
Keck & Wood developed a map viewing software package called MOSAIC MapViewer. This new software was built on ESRI’s MapObjects. Since this new system would be used by field crews with little to no mapping or computer experience, Keck & Wood developed the software to be very easy to use and made it touch screen enabled. When coupled with the Panasonic Toughbook, a field hardened laptop, MOSAIC MapViewer has proven to be a great tool for the Gas System’s crews, saving them time and money.
On-site GIS Training, City of Atlanta, Georgia
City of Atlanta (Georgia) On-site GIS Training – This project entailed holding several GIS classes including ESRI’s Introduction to ArcGIS I and II courses and Keck & Wood’s Using AutoCAD Data in ArcGIS course for the City of Atlanta. These classes were held on-site at the City’s Courthouse building located near City Hall and the State Capitol.
Keck & Wood conducted three (3) Introduction to ArcGIS I and II classes each for the City. These were the official classes developed by ESRI to teach new users the basic functionality found in ArcGIS Desktop Software (ArcView, ArcEditor and ArcInfo). These classes consisted any where from 14 to 18 students from various City departments including planning, police, fire, airport, engineering, watershed management, public works, finance, economic development, and public housing. Keck & Wood provided an experienced ESRI Authorized, an assistant instructor, course materials for each student, and follow up help and support for each student.
In addition to the official ESRI developed classes, Keck & Wood held two (2) “Using AutoCAD data in ArcGIS” classes. This class was developed by Keck & Wood to show ArcGIS users how they can use data created by engineers and surveyors in AutoCAD to update their GIS database.
All classes were very successful based on the feedback we received from the students as illustrated below:
“Great instructor. Class material was educational and interesting.” Jimmy Hodges - City of Atlanta Fire Dept. – Introduction to ArcGIS I
“An outstanding course for users with an entry-level understanding of ArcGIS. The materials in this course are invaluable. The instructor demonstrated a high proficiency of teaching skills in a subject that is difficult to communicate to students.” Joseph Maxberry - Atlanta Development Authority – Introduction to ArcGIS II
Data Conversion & Model Creation, Gilmer County Tax Assessors Office, Georgia
Keck & Wood converted the County's existing AutoCAD tax maps to an ArcGIS personal geodatabase. We worked with the County and ESRI to develop the database design. Once the data was converted, Keck & Wood did three years worth of updates to the parcel data. When the updates were completed, we delivered three geodatabases, one covering the entire County and two representing the north and south halves of the County. The two geodatabases representing the two halves of the County were created to allow multi-user editing until the County could purchase ArcSDE.
Keck & Wood created a model using ESRI’s Model Builder that merges the two editing geodatabases into a single geodatabase with a single click of a button. The merged geodatabase is the one used for analysis, plotting and sharing with other departments.
Keck & Wood assisted County personnel in creating a County Zoning map. We also set-up a booklet plotting routine for plotting either 11x17 or 24x36 tax and zoning map booklets. In addition, Keck & Wood provided and installed two HP Color LaserJet 5550 DN printers.
Color Orthophotography & Tax Map Adjustment, Jones County, Georgia
This project entailed capturing new digital color orthophotography and adjusting the existing tax map data to overlay the new aerials. The new orthophotography has been orthorectified to the USGS DEM with supplemental GPS control points and delivered to the County. Keck & Wood then adjusted the County’s existing GIS tax map data to overlay the new aerials and converted the data from AutoCAD DWG format to an ESRI Geodatabase. Upon completion the County received 1 foot pixel georeferenced images for the entire County and ½ foot pixel georeferenced images for the City of Gray and Macon in both ECW and Tiff formats, a complete set of 24” x 36” mylar tax maps, an 11” x 17” tax map booklet both with and without aerials and a copy of all the data on DVD-ROM.
GIS Data Conversion, Tax Map & Zoning Map Creation & Updates, Coffee County, Georgia
This project entailed converting the original digital tax map data from an AutoCAD DWG format to an ArcGIS Geodatabase, linking the parcels to the County’s Tax Digest, creating a Zoning layer, and setting up an in-house GIS for analysis and plotting using ESRI's ArcView 9.1 software. Keck & Wood had originally created the AutoCAD data used for the conversion during a previous project.
The conversion included over 15,000 parcels that then were linked to the County’s tax digest. Keck & Wood created reports indicating parcels found on the maps but not in the database and parcel records in the digest database but not on the maps. Once the parcels had been converted, Keck & Wood created a zoning layer using County provided paper maps.
Keck & Wood provides ongoing GIS support, training and update services for the County.
GIS Development, Installation, Support, & Training, City of Austell, Georgia
This project entailed converting existing map data obtained from the Austell Natural Gas System from AutoCAD DWG format to ESRI's ArcView Shapefile format creating a base map for the City. Then Keck & Wood digitized existing paper maps, including Street, Zoning, Future Land Use, Sewer System, Water System and Storm Water Maps, to overlay the base map.
Keck &Wood assisted the City in setting up an in-house GIS capable of plotting, querying, analysis, and limited editing using ESRI's ArcView 3.x software. This included creation of ArcView project files, legend files, plot layouts, installation of software and data, plotter setup, and onsite training.
Keck & Wood provides ongoing GIS data update services, engineering services, and hardware/software support and training.
Tax Map Data Conversion, Zoning Map Creation & GIS Data Updates, Upson County, Georgia
This project entailed creating digital rectified aerial photography, a GPS control network, digitizing tax parcel maps, creating a digital Zoning Map, installing an in-house GIS and providing training for the Tax Assessor’s Office.
The first step of this project was to create a GPS control network for the County by locating the road centerlines with a mapping grade GPS system. A new aerial flight was done which was then scanned and rectified to GPS control network. Once the new aerials had been rectified, Keck & Wood digitized the existing County paper tax maps to overlay the new aerials. The new digital tax maps were then linked to the County’s tax digest.
Once the final tax maps and aerials were completed, Keck & Wood created a digital County Zoning map. The Zoning map was created using County provided paper maps which used to created polygons that overlaid the new created tax parcel data.
Keck & Wood installed an in-house GIS giving County personnel the ability to perform queries, analysis and plotting. This system is powered by ESRI ArcView 9.x software. Keck & Wood also provided training to the County staff on the new Mapping/GIS.
Keck & Wood provides on-going services related to tax map and GIS data updates, software and hardware support, and GIS training.
