EXECUTIVE SUMMARY

This report presents the analysis of the anticipated traffic impacts of a proposed 40.4-acre mixed-use development (Georgia 400 Center) located in the City of Alpharetta, Georgia. This report is being prepared as part of a submittal requesting a Master Plan Amendment. Because the project will exceed 400,000 square feet, the proposed development is a Development of Regional Impact (DRI) and is subject to Georgia Regional Transportation Authority (GRTA) and Atlanta Regional Commission (ARC) review. The proposed development is expected to consist of approximately 458 dwelling units, a 150-room hotel, 446,400 SF of office, 90,100 SF of retail, 10,000 SF of quality restaurant space, and 12,000 SF of sit-down restaurant space. The development is scheduled to be completed in multiple phases, with build-out by the year 2011. It should be noted that this site plan is an amendment to the previous site plan developed for this site approved in 1997. Currently, the site is approved for 239,400 square feet of retail / hotel space and 890,960 square feet of office space. The results of the detailed intersection analysis for the 2011 No-Build (excluding the Georgia 400 Center development) and 2011 Build conditions (including the Georgia 400 Center development) identified improvements that will be necessary in order to maintain the Level of Service standard (LOS D or E) within the study network. These improvements are listed below:

2011 No-Build recommended improvements (includes background growth but does not include the Georgia 400 Center DRI project traffic):

Morrison Parkway at Hembree Road (Intersection #1) Install an additional southbound right-turn lane along Hembree Road, creating dual right-turn lanes with a right-turn overlap signal phase (green arrow). (Improvement recommended in DRI #388) Install an additional eastbound left-turn lane, creating dual left-turn lanes, with protected-only phasing (green arrow). Convert the eastbound right-turn lane to a shared through/right lane, creating three eastbound through lanes along Morrison Road. Note: the outside through lane becomes a right-turn lane at the downstream intersection of Lakeview Parkway. Install an additional westbound through lane, creating three westbound through lanes along Morrison Parkway. Change the westbound right-turn lane along Morrison Parkway to free-flow. Hembree Road will need to be widened to accommodate this improvement and should be tapered back to two lanes after a sufficient distance. (A similar improvement was recommended in DRI #388.) (Note: DRI #388 made different improvement recommendations at the intersection.) Morrison Parkway at Lakeview Parkway (Intersection #2) Install an additional westbound through lane along Morrison Parkway, creating three westbound through lanes. Morrison Parkway / Westside Parkway at Haynes Bridge Road Intersection #3 Install an additional eastbound right-turn lane along Morrison Parkway, creating dual right-turn lanes with a right-turn overlap signal phase (green arrow). (Improvement recommended in DRI #698) Install an additional northbound left-turn lane to create triple northbound left-turn lanes along Haynes Bridge Road. (Three receiving lanes will be needed along westbound Morrison Parkway.) (Note: DRI #388 made different improvement recommendations at the intersection.)

O:\019626000 iii October 2007 Georgia 400 Center DRI #1566 Transportation Analysis

Haynes Bridge Road Lakeview Parkway / Northwinds Parkway Intersection #4 Create a free-flow eastbound right-turn lane along Lakeview Parkway. An additional lane will be needed south of the intersection along Haynes Bridge Road. It is recommended that this additional lane be extended to the southbound right-turn lane at the Georgia 400 Southbound Ramp. (A similar improvement was recommended in DRI #698.) Change the eastbound left-turn phasing to protected/permissive (green arrow). (A similar improvement was recommended in DRI #698.) (Note: DRI #698 made different improvement recommendations at the intersection.) Haynes Bridge Road at Georgia 400 Southbound Ramps (Intersection #5) Install an additional eastbound left-turn lane along the Georgia 400 ramp, creating dual left-turn lanes. (A similar improvement was recommended in DRI #698.) Install an additional southbound right-turn lane, creating dual right-turn lanes with a right-turn overlap signal phase (green arrow). (A similar improvement was recommended in DRI #698.) Haynes Bridge Road at Georgia 400 Northbound Ramps (Intersection #6) Install an additional southbound left-turn lane, creating dual left-turn lanes along Haynes Bridge Road. (Improvement recommended in DRI #388 and DRI #698.) Install an additional northbound through lane, creating four through lanes along Haynes Bridge Road. Install an additional eastbound left-turn, creating triple left-turns along the Georgia 400 ramps. (Note: DRI #698 made different improvement recommendations at the intersection.) Haynes Bridge Road at North Point Drive (Intersection #7) Install an additional westbound right-turn lane, creating dual right-turn lanes with a right-turn overlap signal phase (green arrow) along North Point Drive.

2011 Build recommended improvements (includes the traffic associated with the Georgia 400 Center DRI): NOTE: These improvements are in addition to the improvements listed previously in the 2011 No-Build.

Haynes Bridge Road at Lakeview Parkway / Northwinds Parkway (Intersection #4) Install an additional northbound left-turn lane along Haynes Bridge Road with protected-only phasing. The westbound left-turn lane along Lakeview Parkway should be extended to maximize vehicle storage.

Project driveway recommendations for the Georgia 400 Center DRI:

O:\019626000 iv October 2007 Georgia 400 Center DRI #1566 Transportation Analysis

Lakeview Parkway would be two lane approaches, with a shared left-turn/through lane and a shared through/right-turn lane. The northbound approach (proposed Driveway #2) would be a shared left- turn/through lane and a separate right-turn only lane. The roundabout is recommended to have a minimum outside (inscribed) diameter of 150 feet, 15 foot wide circulating travel lanes, and a mountable truck apron on the edge of the central island to provide for larger vehicle tracking. All approaches should include splitter islands to physically separate entry and exit vehicles on an approach and provide a refuge for pedestrians. All approaches should include pedestrian crossings. The roundabout is recommended to be designed to accommodate a WB-67 design vehicle. Lakeview Parkway at Driveway #3 / 2400 Lakeview Parkway Driveway (Intersection #11) A signal should be installed at this location with protected-permitted westbound left-turn phasing. This new signal should be coordinated with the existing signal at Lakeview Parkway / Haynes Bridge Road (Intersection #4). (Note: It is recommended that the existing median opening be relocated to the west to provide sufficient westbound left-turn storage to reduce vehicle queue interactions with the upstream signal at Lakeview Parkway / Haynes Bridge Road (Intersection #4)). Provide a northbound left-turn lane and a shared through/right-turn lane exiting the site along Driveway #3. Additionally, the existing 2400 Lakeview Parkway driveway should be restriped to provide a southbound left-turn lane and a shared through/right-turn lane. Haynes Bridge Road at Driveway #4 (Right-In / Right-Out) (Intersection #12) Provide an eastbound right-turn only lane exiting the site along Driveway #4.

1.0 PROJECT DESCRIPTION

1.1 Introduction This report presents the analysis of the anticipated traffic impacts of a proposed 40.4-acre mixed-use development (Georgia 400 Center) located in the City of Alpharetta, Georgia. This report is being prepared as part of a submittal requesting a Master Plan Amendment. Because the project will exceed 400,000 square feet, the proposed development is a Development of Regional Impact (DRI) and is subject to Georgia Regional Transportation Authority (GRTA) and Atlanta Regional Commission (ARC) review. The proposed development is expected to consist of approximately 458 dwelling units, a 150-room hotel, 446,400 SF of office, 90,100 SF of retail, 10,000 SF of quality restaurant space, and 12,000 SF of sit-down restaurant space. The development is scheduled to be completed in multiple phases, with build-out by the year 2011. It should be noted that this site plan is an amendment to the previous site plan developed for this site approved in 1997. Currently, the site is approved for 239,400 square feet of retail / hotel space and 890,960 square feet of office space. A summary of the proposed land-uses and densities can be found below in Table 1. Table 1 Proposed Land Uses Residential Units 458 dwelling units Hotel 150 rooms General Office Building 446,400 square feet Retail (Shopping Center) 90,100 square feet Quality Restaurant 10,000 square feet High-Turnover (Sit-Down) Restaurant 12,000 square feet

Figure 1 and Figure 2 provide a location map and an aerial photograph of the site.

1.2 Site Plan Review The development is located along the south side of Lakeview Parkway just west of Haynes Bridge Road in the City of Alpharetta. Office buildings are planned along Lakeview Parkway, mixed with surface parking. Driveway #2 at the proposed roundabout along Lakeview Parkway opens to a street leading to a fountain at the end of the street surrounded by a restaurant and a 12-story office building. Residential units are proposed along either side of this street. Flex space is scattered throughout the central and eastern portions of the development, intended for retail and/or office use. Two restaurants are situated along the eastern boundary along Haynes Bridge Road. The existing lake to the south of the development will remain. The area surrounding the proposed development is also owned by MetLife and currently office space. All surrounding office buildings are to remain. Figure 3 is a small-scale copy of the site plan. A full-size site plan consistent with GRTA’s Site Plan Guidelines is also being submitted as part of the Review Package.

1.3 Site Access A total of four access points are proposed to serve the proposed development: Two access points to the proposed Georgia 400 Center development are proposed along Lakeview Parkway, one is proposed along an existing access road just west of Lakeview Parkway and one is proposed along Haynes Bridge Road.

The northernmost driveway, Driveway #1, is a connection to the existing 2325 Lakeview Parkway office driveway along the west property line, which connects to Lakeview Parkway. The intersection of 2325 Lakeview Parkway and Lakeview Parkway was analyzed.

A roundabout is proposed at the western full-movement driveway (Driveway #2) along Lakeview Parkway approximately 820 feet east of Morrison Parkway along Lakeview Parkway. Two existing median openings are proposed to be closed and a new median opening will be created along Lakeview Parkway at the location of Driveway #2. This median opening will also serve the existing Georgia 400 Center office park to the north via a relocated driveway for 2300 Lakeview Parkway.

The eastern full-movement driveway, Driveway #3, is proposed along Lakeview Parkway approximately 340 feet west of Haynes Bridge Road. A signal, along with the relocation of the existing median opening to the west, is recommended at this driveway. The existing driveway at this median opening is 2400 Lakeview Parkway, currently serving the existing Georgia 400 Center office park.

Driveway #4 is a proposed right-in/right-out driveway along Haynes Bridge Road located approximately 260 feet south of Lakeview Parkway.

Approximate distances along Lakeview Parkway:

Note: It is approximately 1,960 feet along Lakeview Parkway between Morrison Parkway (centerline) and Haynes Bridge Road (centerline). The City of Alpharetta will be the permitting agency for the site driveway along Lakeview Parkway.

1.4 Bicycle and Pedestrian Facilities Pedestrian facilities (sidewalks) currently exist in the vicinity of the proposed site along both sides of Lakeview Parkway and Haynes Bridge Road.

1.5 Transit Facilities The closest transit facility to the proposed development is the MARTA Mansell Center Park and Ride Lot, located off of Mansell Road, one exit south of Haynes Bridge Road on GA 400.

2.0 TRAFFIC ANALYSES METHODOLOGY AND ASSUMPTIONS

2.1 Growth Rate Background traffic is defined as expected traffic on the roadway network in future year(s) absent the construction and opening of the proposed project. Historical traffic count data from the Georgia DOT was reviewed for the area surrounding the proposed development, and growth rates of 1.5% per year along all roadways were agreed upon during the methodology meeting with GRTA staff. Additionally, traffic associated with other projects in the area with study networks that impacted with the intersections listed in Section 3.4 were added. The amount of development built was determined to ensure only traffic associated with unbuilt portions of the project was added onto the project. Investigation of the projects in the area showed that three other projects had a study network that overlapped with the one in this report. Additionally, a portion of one of these (DRI #388) had already been built, therefore the trips associated with this project were reduced. Below is a summary of background traffic assumptions agreed to by GRTA:

• DRI # 388 - Cousins Westside - PODs C,E, and N have been fully built-out (311 townhomes); therefore, the project trips were reduced by this amount and the remaining project trips were added onto the network.

• DRI #698 - Forum at Alpharetta - 100% of project traffic was added on as background traffic, since build- out is scheduled for 2008.

• Rock Mill Road Development - 100% of project traffic was added on as background traffic, since build- out is scheduled for 2009.

2.2 Traffic Data Collection 2007 peak hour turning movement counts were conducted at eight signalized intersection and three unsignalized intersections between 7:00-9:00 AM and 4:15-6:15 PM. The morning and afternoon peak hours varied between the eleven intersections: 1. Morrison Parkway at Hembree Road (AM Peak 7:45-8:45, PM Peak 5:00-6:00) 2. Morrison Parkway at Lakeview Parkway (AM Peak 7:30-8:30, PM Peak 4:45-5:45) 3. Morrison Parkway at Haynes Bridge Road (AM Peak 7:30-8:30, PM Peak 5:15-6:15) 4. Haynes Bridge Road at Lakeview Parkway / Northwinds Parkway (AM Peak 7:45-8:45, PM Peak 5:00-6:00) 5. Haynes Bridge Road at Georgia 400 Southbound Ramps (AM Peak 7:30-8:30, PM Peak 5:00-6:00) 6. Haynes Bridge Road at Georgia 400 Northbound Ramps (AM Peak 7:45-8:45, PM Peak 4:30-5:30) 7. Haynes Bridge Parkway at North Point Drive (AM Peak 7:45-8:45, PM Peak 5:00-6:00) 8. Haynes Bridge Road at North Point Parkway (AM Peak 7:30-8:30, PM Peak 4:45-5:45) 9. Lakeview Parkway at 2325 Lakeview Driveway (AM Peak 8:00-9:00, PM Peak 4:45-5:45) 10. Lakeview Parkway at 2300 Lakeview Driveway (AM Peak 7:45-8:45, PM Peak 4:15-5:15) 11. Lakeview Parkway at 2400 Lakeview Driveway (AM Peak 7:45-8:45, PM Peak 4:45-5:45) All raw count data is available upon request.

2.3 Detailed Intersection Analysis Level-of-service (LOS) is used to describe the operating characteristics of a road segment or intersection in relation to its capacity. LOS is defined as a qualitative measure that describes operational conditions and motorists perceptions within a traffic stream. The Highway Capacity Manual defines six levels of service, LOS A through LOS F, with A being the best and F being the worst. Level of service analyses were conducted at all intersections within the study network using Synchro Professional, Version 6.0. Levels of service for signalized intersections are reported for the intersection as a whole. One or more movements at an intersection may experience a low Level of service, while the intersection as a whole may operate acceptably. Levels of service for unsignalized intersections, with stop control on the minor street only, are reported for the side street approaches. Low Levels of service for side street approaches are not uncommon, as vehicles may experience delay in turning onto a major roadway. For the roundabout analysis, aaSIDRA software was utilized. The aaSIDRA roundabout analysis program is the software package recommended in TOPPS 4A-2, a document of guidelines for roundabouts issued by the Georgia Department of Transportation.

3.0 STUDY NETWORK

3.1 Gross Trip Generation As stated earlier, the proposed development is expected to consist of approximately 458 dwelling units, a 150- room hotel, 446,400 SF of office, 90,100 SF of retail, 10,000 SF quality restaurant space, and 12,000 SF of sit- down restaurant space. The development is scheduled to be completed in multiple phases, with build-out by the year 2011. Traffic for these land uses was calculated using equations contained in the Institute of Transportation Engineers’ (ITE) Trip Generation Manual, Seventh Edition, 2003. Gross trips generated are displayed on the following page in Table 2.

3.2 Trip Distribution The directional distribution and assignment of new project trips was based on engineering judgment and discussions with GRTA staff at the methodology meeting.

3.3 Level of Service Standards For the purposes of this traffic analysis, a level of service standard of D was assumed for all intersections and segments within the study network. If, however, an intersection or segment currently operates at LOS E or LOS F during an existing peak period, the LOS standard for that peak period becomes LOS E, consistent with GRTA’s Letter of Understanding.

3.4 Study Network Determination A general study area was determined using the 7% rule. This rule recommends that all intersections and segments be analyzed which are impacted to the extent that the traffic from the proposed site is 7% or more of the Service Volume of the facility (at a previously established LOS standard) be considered for analysis. This general study area was refined during the methodology meeting, and includes the following intersections: o Morrison Parkway at Hembree Road o Morrison Parkway at Lakeview Parkway o Morrison Parkway at Haynes Bridge Road o Haynes Bridge Road at Lakeview Parkway / Northwinds Parkway o Haynes Bridge Road at Georgia 400 Southbound Ramps o Haynes Bridge Road at Georgia 400 Northbound Ramps

O:\019626000 5 October 2007 Georgia 400 Center DRI #1566 Transportation Analysis

o Haynes Bridge Road at North Point Drive o Haynes Bridge Parkway at North Point Parkway Each of the above listed intersections was analyzed for the Existing 2007 Condition, the 2011 No-Build Condition, and the 2011 Build Condition. The 2011 No-Build Condition represents the existing traffic volumes grown at 1.5% per year for four (4) years, plus the addition of traffic associated with other developments in the area. The 2011 Build Condition adds the projected trips associated with the Georgia 400 Center development to the 2011 No-Build Condition. (NOTE: The additional proposed site access points listed below were only analyzed for the 2011 Build Condition): o Lakeview Parkway at 2325 Lakeview Parkway (This existing driveway will provide access to Driveway #1) o Lakeview Parkway at Driveway #2 / 2300 Lakeview Parkway o Lakeview Parkway at Driveway #2 / 2400 Lakeview Parkway o Haynes Bridge Road at Driveway #4 These intersections were analyzed for the AM and PM peak periods.

(A similar improvement was recommended in DRI #698.) Haynes Bridge Road at Georgia 400 Northbound Ramps (Intersection #6) Install an additional southbound left-turn lane, creating dual left-turn lanes along Haynes Bridge Road. (Improvement recommended in DRI #388 and DRI #698.) Install an additional northbound through lane, creating four through lanes along Haynes Bridge Road. Install an additional eastbound left-turn, creating triple left-turns along the Georgia 400 ramps. (Note: DRI #698 made different improvement recommendations at the intersection.) Haynes Bridge Road at North Point Drive (Intersection #7) Install an additional westbound right-turn lane, creating dual right-turn lanes with a right-turn overlap signal phase (green arrow) along North Point Drive.

6.3 2011 Build Traffic The traffic associated with the proposed development (Georgia 400 Center) was added to the 2011 No-Build volumes. These volumes were then input into Synchro 6.0 with the recommended No-Build geometry improvements from the previous section. Lakeview Parkway at Driveway #2 / 2300 Lakeview Parkway Driveway (Intersection #11) was analyzed using SIDRA software to determine the roundabout capacity and level of service. The results of the analyses are displayed in Table 7. The projected volumes, laneage, and recommended intersection control for the year 2011 Build condition are illustrated in Figures 9A and 9B.

The right-in / right-out driveway is projected to handle low entering and exiting traffic volumes. The right-out only driveway is expected to operate at an acceptable level of service due to low traffic volumes. As shown in Table 7, the intersection of Haynes Bridge Road at Lakeview Parkway / Northwinds Parkway (Intersection #4) failed to meet the acceptable Level of Service standard for the AM peak hour. Improvements were made to the 2011 Build Conditions to obtain the appropriate LOS Standard. The 2011 Build with Improvements intersection analysis Level of Service are displayed below in Table 8.

2011 Build recommended improvements (includes the traffic associated with the Georgia 400 Center DRI): NOTE: These improvements are in addition to the 2011 No-Build improvements listed previously..

The proposed site driveways were analyzed for the 2011 Build conditions. Table 7 includes the Level of Service analysis results for the proposed site driveways. The 2011 Build intersection volumes, laneage, and recommended intersection control is illustrated in Figures 9B.

Lakeview Parkway at Driveway #2 / 2300 Lakeview Parkway Driveway (Intersection #10) Relocate the existing 2300 Lakeview Parkway Driveway and close the existing median opening. Install a modern two-lane roundabout with one 1-lane approach (2300 Office Driveway) and three 2- lane approaches. The proposed roundabout should incorporate design parameters recommended in the FHWA Roundabout Guide as well as current state of the practice design standards for modern roundabouts, including pavement markings. The westbound and eastbound approaches along Lakeview Parkway would be two lane approaches, with a shared left-turn/through lane and a shared through/right-turn lane. The northbound approach (proposed Driveway #2) would be a shared left- turn/through lane and a separate right-turn only lane. The roundabout is recommended to have a minimum outside (inscribed) diameter of 150 feet, 15 foot wide circulating travel lanes, and a mountable truck apron on the edge of the central island to provide for larger vehicle tracking. All approaches should include splitter islands to physically separate entry and exit vehicles on an approach and provide a refuge for pedestrians. All approaches should include pedestrian crossings. The roundabout is recommended to be designed to accommodate a WB-67 design vehicle. Lakeview Parkway at Driveway #3 / 2400 Lakeview Parkway Driveway (Intersection #11) A signal should be installed at this location with protected-permitted westbound left-turn phasing. This new signal should be coordinated with the existing signal at Lakeview Parkway / Haynes Bridge

O:\019626000 13 October 2007 Georgia 400 Center DRI #1566 Transportation Analysis

Road (Intersection #4). (Note: It is recommended that the existing median opening be relocated to the west to provide sufficient westbound left-turn storage to reduce vehicle queue interactions with the upstream signal at Lakeview Parkway / Haynes Bridge Road (Intersection #4)). Provide a northbound left-turn lane and a shared through/right-turn lane exiting the site along Driveway #3. Additionally, the existing 2400 Lakeview Parkway driveway should be restriped to provide a southbound left-turn lane and a shared through/right-turn lane. Haynes Bridge Road at Driveway #4 (Right-In / Right-Out) (Intersection #12) Provide an eastbound right-turn only lane exiting the site along Driveway #4.

9.0 INTERNAL CIRCULATION ANALYSIS The proposed development will generate trips between the residential and non-residential uses. The internal roadway network connects the residential units with the office space and the retail / restaurant. Using the ITE Trip Generation Handbook, 2004 as a reference, approximately 14.54% of the gross daily trips will be internal and approximately 12.27% of the gross PM peak hour trips will be internal.

10.0 COMPLIANCE WITH COMPREHENSIVE PLAN ANALYSIS The City of Alpharetta Future Land Use Map designates this area as Office Center.

11.0 NON-EXPEDITED CRITERIA

11.1 Quality, Character, Convenience, and Flexibility of Transportation Options There are no transit facilities or bus routes in the vicinity of the proposed site; however it is expected that carpooling will occur between employees due to the density of office space in and around the proposed development.

11.2 Vehicle Miles Traveled The following table displays the reduction in traffic generation due to internal capture and pass-by trips.

Build-out Total Daily Gross Trip Generation: 16,865 (-)Mixed-use reductions (internal capture) -2,452 (-)Pass-by trips -136 (-)Alternative modes -2,298 Net Trips: 11,979

11.3 Relationship Between Location of Proposed DRI and Regional Mobility The proposed development is located along a major limited-access facility, SR 400, at the Haynes Bridge Road interchange.

11.4 Relationship Between Proposed DRI and Existing or Planned Transit Facilities The proposed DRI is not within walking distance to any transit facilities or bus routes. The closest transit facility to the proposed development is the MARTA Mansell Center Park and Ride Lot, located off of Mansell Road, one exit south of Haynes Bridge Road on GA 400.

11.5 Transportation Management Area Designation The proposed development is not located within an established TMA.

11.6 Offsite Trip Reduction and Trip Reduction Techniques Mixed-use and pass-by trip reductions were taken according to the ITE Trip Generation Handbook, 2004. Approximately 14.54% of the gross daily trips will be internal and approximately 12.27% of the gross PM peak hour trips will be internal.

11.7 Balance of Land Uses – Jobs/Housing Balance Please refer to the Area of Influence Analysis, located in Section 12.0 of the report.

11.8 Relationship Between Proposed DRI and Existing Development and Infrastructure The No-Build improvements to the existing infrastructure listed in this report will be necessary to support traffic volumes in build-out year (2011).

12.0 AREA OF INFLUENCE The proposed development, Georgia 400 Center, is expected to consist of 458 residential dwelling units, 446,400 SF of office space, a 150-room hotel, a 10,000 SF quality restaurant, 12,000 SF of high-turnover restaurant space, and 90,100 SF of retail space. Due to the nature of the development, it is classified as “predominantly employment” for the purposes of this AOI. The following section will describe the Area of Influence demographics, DRI average wage levels, expected AOI housing costs, and the opportunity for workers who are employed in the DRI to find housing within the AOI.

12.1 Criteria As part of the non-expedited review process for a DRI, an Area of Influence Analysis must be performed to determine the impact of the proposed development on the balance of housing and jobs within the immediate area surrounding the development. For this proposed development classified as “predominantly employment,” the non-expedited review criterion is as follows: The proposed DRI: (b) Is located in an Area of Influence where the proposed DRI is reasonably anticipated to contribute to the balancing of land uses within the Area of Influence such that twenty-five percent (25%) of the persons that are reasonably anticipated to be employed in the proposed DRI have the opportunity to live within the Area of Influence;

12.2 Study Area Determination and Characteristics The Area of Influence is comprised of the area within six road-miles of the proposed development. To determine the AOI, TransCAD was used to measure six road miles from the nearest intersection to the project (Lakeview Parkway at Haynes Bridge Road). The population and housing statistics for the AOI were determined by taking the area outlined in TransCAD, creating a boundary in GIS format, and overlaying the boundary with a GIS layer containing census tract information. The Area of Influence (located within Fulton and Forsyth counties) can be seen in Figure 10. The total population within the Area of Influence is 126,452, residing within 47,819 households (an average of 2.63 people per household). There are approximately 68,869 workers in the AOI for an average of 1.44 workers per household. The AOI area over the two counties totals 46,326 acres.

12.3 DRI Employment and Salary Figures The DRI is expected to employ approximately 1,865 workers in the following land uses: General Office, Hotel, Restaurant, and Retail. The numbers of workers for the office, hotel, restaurant, and shopping center land uses are based on assumptions provided in the Area of Influence (AOI) Guidebook for Non-Expedited Reviews, April 2003. For the office land use, 1 employee per 300 SF yields 1,850 office employees. For the specialty retail land use, 1 employee per 560 SF results in 43 retail employees. Hotel land uses are expected to employ approximately 0.9 workers per hotel room. Sit-down restaurants are estimated to employ one employee per 300 square feet, while quality restaurants are expected to employ one employee per 450 square feet. For the office land use, employees are assumed to work in the following occupations: management, technical, office and administrative support, computers, and business and financial operations. The specialty retail land use includes retail managers and retail salespersons. For the hotel land use, it is assumed that employment will be comprised of the following occupations: lodging managers, bellhops, housekeepers, desk clerks, and food preparers and servers. Using the departmental and occupational guidelines provided by the client, along with the U.S. Department of Labor’s May 2005 Metropolitan Area Occupational Employment and Wage Estimates Atlanta-Sandy Springs- Marietta, GA, salaries were approximated for each occupation. The following occupational codes were used for the above jobs:

11-9081 Lodging Managers 35-0000 Food Preparation and Serving Related Occupations 37-2012 Maids and Housekeeping Cleaners 39-6011 Baggage Porters and Bellhops 11-0000 Management Occupations 13-0000 Business and Financial Operations Occupations 15-0000 Computer Occupations 17-0000 Technical Occupations 41-1011 Managers of Retail Sales 41-2031 Retail Salespersons 43-0000 Office and Administrative Support Occupations

Household salary was calculated based on the computed workers per household ratio of 1.44 multiplied by the salary in each bracket. It is assumed then that each household has 1.44 workers who contribute to the monthly household salary. The affordable housing payment is calculated as 30% of the monthly household salary, as based on GRTA’s Area of Influence (AOI) Guidebook for Non-Expedited Reviews. Table 9 displays the department positions, the numbers of employees in each occupation, the monthly employee and household salaries, and the respective affordable housing payments.

12.4 AOI Occupied Housing Figures An analysis of existing occupied housing was conducted based on 2000 Census data for owner- and renter- occupied housing. A GIS analysis identified approximately 29,000 owner-occupied units and 15,000 renter- occupied units in the AOI. Table 11 below displays the housing units in comparable price tiers as are shown in Table 12. Owner-occupied housing includes housing with and without a mortgage. Renter-occupied housing includes all rental units with the exception of those with no cash rent.

Using the households in the DRI per price tier information in Table 10 and the renter / owner distribution of occupied housing in the AOI in Table 11 above, a comparison was done to analyze the available housing by price range within the AOI against the number of households per price tier expected within the proposed DRI. This comparison is shown below in Table 12.

Table 12 Comparison of Workers’ Monthly Household Incomes in the DRI and Monthly Costs of Housing Units in the AOI

As can be seen from Table 12, adequate housing opportunities exist for all wage-earning levels in the DRI for both owner and renter properties. Additionally, because the salaries of the employees are concentrated at the upper limits of the price tiers, considerable extra housing is available in lower price tiers if a household desires to choose a more conservative price range. Given this information, over 25% of the employees of the DRI have an opportunity to reside within the Area of Influence.

13.0 ARC’S AIR QUALITY BENCHMARK The proposed development is expected to consist of approximately 458 dwelling units, a 150-room hotel, 446,400 SF of office, 90,100 SF of retail, 10,000 SF of quality restaurant space, and 12,000 SF of sit-down restaurant space. Assuming each residence is the ARC-accepted average of 1,800 SF, residential is the dominant use and the dwelling units per acre ratio is approximately 10 units / acre. Based on this density, the development is projected to meet a density target for a 4% reduction. The mixed-use proposed development contains more than 10% of floor area for office space. Thus, the proposed site may receive a 4% VMT reduction. The proposed development will provide connections between the residential and non-residential uses within the site. Thus, the proposed site may receive a 4% VMT reduction. The proposed development meets the ARC criteria for a total 12% VMT reduction. These reductions are displayed below in Table 13.
