Transportation Network Revisions
Transportation Updates 1. 2. 3. Roadways 1. Shellhorn Road and Lockridge Road have been realigned in accordance with October 4, 2016 BOS Direction 2. Third proposed Broad Run crossing has been removed due to realigned Shellhorn Road and changes to land use and travel patterns Transit 3. Metro circulators have been rerouted based upon public comments and changes to roadway network
Updated Streets Plan
Silver Line Area Circulator Routes
Transportation Model Based upon total development forecasted through 2040 Evaluates the overall functionality of proposed transportation network Takes a conservative approach (Almost everyone traveling alone by car) Model will continue to be refined as part of VDOT review of CPAM
Model Outputs Transportation network is forecast to operate acceptably through 2040 Some road segments may be congested during peak hours, but no corridors are forecasted to be over capacity While some traffic congestion is anticipated, this is typical of dense urban environments
PM Peak Hour Results Existing CTP Network (with Iteration 3 land uses) Proposed CTP Network (with Iteration 3 land uses)
Comparison to Nearby Urban Centers Silver Line Policy Area Reston Town Center
Transportation Network Findings The proposed network accommodates the anticipated traffic generated by the increased land use density The proposed network encourages use of transit, bicycling, and walking The forecasted levels of congestion are less severe than in comparable urban centers
Fiscal Impact Analysis
Change to the overall fiscal balance within the County ( Fiscal Impact ) Capital facility needs Key Questions Revenues for the Metrorail Service Tax District Metrorail service tax district revenues can be used to fund Metrorail capital costs. Payments for Metrorail operating costs are not included in this analysis.
Examining Change Comparing the proposed plan to the current plan: impact of the difference Countywide Fiscal Balance Countywide Change Changes to residential and office development within the plan area result in the same changes Countywide
New Residential Units (Forecasted 2040) Current Plan (incl. entitlements) 7,142 total units Proposed Plan 22,251 total units Proposed Plan 4,402 additional single-family attached 10,707 additional multi-family 15,109 additional units
Methodology Focus on 15,000 additional units and 2.5 million SF Office in the year 2040 Use reduced pupil generation rates and household sizes for multi-family units Identify need for new capital facilities based on current standards Characterize change in fiscal balance using FY 2016 budget and constant dollars Forecast tax district revenues using $0.20 real property tax rate
Sensitivity Tests Fiscal Balance; Capital Needs Balance of residential and nonresidential development Number of residents and school children per multi-family unit Per Unit Pupils Residents Plan vision: small multi-family units 0.15 1.87 Current multi-family rates 0.23 1.97 Tax District Revenues; Capital Financing Costs When and how rapidly development occurs
Capital Facility Needs, 2040 About half the cost of the nontransportation portion of the current CIP Using current, conservative standards, about 300 acres of land would be needed If not offset by developer contributions, costs equate to adding a school to the CIP each year
Change in the Countywide Fiscal Balance, 2040 For the mix of development and smaller multi-family units envisioned for the proposed plan Revenues Operating Expenditures Net Operating Flows Capital Expenditures Related to Affordable Units Fiscal Impact $91 M - $84.3 M $6.7 M - $4.7 M $2 M Capital expenditures based on residential development over 23 years
Key Points: Countywide Fiscal Balance Comprehensive Plan Amendment can be fiscally positive Balance of residential and nonresidential development is necessary Residential development must generate fewer residents and school children Developer contributions to offset capital costs are necessary
Tax District Implications
Metrorail Service Tax District Revenues Cumulative increase in revenues as of 2040 Slower/Sooner Development Delayed, then Rapid Development Nonresidential (Office) Development $ 9.1 M $ 4.8 M Residential Development $ 83.3 M $ 44.3 M Total Additional Revenues $ 92.4 M $ 49.1 M

Issue 6 Park and School Locations Approximate size of 1 Urban Recreation Park
Potential School Locations
Schools Growth management policies to ensure residential development does not occur without provision of schools 5,300 to 8,000 new students projected Need for at least 3 ES, 1 MS, 1 HS Schools to be neighborhood serving Student generation rates dependent on unit type Need for continuous monitoring of school needs
Elementary Schools Walkable urban format 900± student capacity Minimize need for bussing Emphasis on pedestrian environment Smaller footprints Integrated into communities
Middle and High Schools Necessitate a more suburban form and location 1,350± student capacity for Middle Schools 1,800± student capacity for High Schools Need to accommodate vehicular traffic Increased need for recreation space Explore smaller footprint designs
