ECONOMIC DEVELOPMENT, LAND USE AND PROPERTY Economic Development Property Value Impacts Land Use Impacts Property Impacts Interchange Design Minimization Displacements
ECONOMIC DEVELOPMENT, LAND USE AND PROPERTY Economic Development All of the Interchange and IL 47 Build Alternatives Accommodate the Proposed Land Use Plan The Land Use Plan is a tool utilized by Sugar Grove Economic Development Corporation (SGEDC) to further their goals Full Access Interchange Connects NHS Routes (important to economy, defense, and mobility)
ECONOMIC DEVELOPMENT, LAND USE AND PROPERTY Property Value Impacts In Phase II, which includes land acquisition, fair market value for property is offered. Independent appraisals are performed. Damage to the remainder of property not acquired is taken into consideration during the appraisal process. $$$
LAND USE AND PROPERTY IMPACTS 8 7 6 5 LEGEND FARMLAND IMPACTS (ACRES) ROW IMPACTS (ACRES) 5.2 7.2 I-3 DDI had the largest farmland and ROW impacts 4 3 2 1 0 0.9 0.7 0.7 0.7 0.1 0 I-1 I-2 I-3 I-4 I-1 I-2 I-3 I-4
LAND USE AND PROPERTY IMPACTS 20 15 LEGEND FARMLAND IMPACTS (ACRES) ROW IMPACTS (ACRES) Widening Towards the East had the most farmland and ROW Impacts 10 5 11.4 5.8 5.8 10.9 7.3 12 0 M-1A M-1C M-2C M-1A M-1C M-2C
DISPLACEMENTS M-1A Widening on Both Sides had six (6) potential residential displacements M-1C M-2C Widening Towards the East resulted in no (0) potential residential displacements
TRAFFIC Traffic Volumes on IL 47 Truck Volumes Impacts of Traffic on Local Roads Bicycle and Pedestrian Accommodations Capacity and Operations
TRAFFIC Traffic Volumes on IL 47 The Population of Sugar Grove and Elburn is projected to triple from 2010 to 2040 Sugar Grove 10,000 to 30,000 Elburn 6,000 to 18,000 Traffic Volumes Increase on IL 47 in the Build and No Build Conditions and are generally the same within the study limits All Build Alternatives have the same traffic projections
TRAFFIC Truck Volumes Part of Purpose and Need is to Improve Connectivity of Truck Routes (Improve System Linkage) Just like overall traffic volumes, Truck Volumes will increase with population growth without any improvements
TRAFFIC Impacts of Traffic on Local Roads Less Cut-Through Traffic on Local Roads All Build Alternatives have the same traffic projections on Local Roads Build Traffic Decreases from No Build GREEN RD SEAVEY ROAD FINLEY RD MERRILL RD COLLEGE DR Increased access to I-88 and IL 47 makes shorter and faster trips than circuitous local routes, which removes traffic from local routes Build Traffic Increases from No Build SCOTT RD College Drive More use of northern WCC entrance due to new route with increased access at I-88 Scott Road Marginal increase in traffic
BICYCLE AND PEDESTRIAN ACCOMMODATIONS Facilities on Both Sides Narrower facilities on west side to Reduce Residential Impacts Path Costs 20% 5 foot Sidewalk 10 foot Multi-Use Path 80% Looking North All Build Alternatives accommodate separated (off-street) facilities for bicycles and pedestrians on IL-47 over I-88 at the interchange
CAPACITY AND OPERATIONS No Build Segment Level of Service (LOS) = D to E Build Segment LOS = A to B All Build Alternatives Operate an Acceptable LOS I-1 Potential Operational Issue Back to Back Left Turn Lanes I-2 Potential Operational Issue Lack of Availability to Flush Ramps I-3 No Operational Issues Anticipated I-4 No Operational Issues Anticipated
SAFETY Traffic Safety Emergency Vehicle Response and Transport
TRAFFIC SAFETY 14 12 10 8 6 4 2 0 Conflict Points The Conventional Diamond has the most conflict points # of Conflict Points I-1 I-2 I-3 I-4
TRAFFIC SAFETY Median / Left Turn Channelization None in the No Build Condition All Build Alternatives have a Median with Left Turn Channelization Median Left Turn Lane Channelization Medians Provide Separation from Opposing Traffic and Reduce Crashes Left Turn Lanes Provide Separation from Thru Traffic and Reduce Rear-End Crashes
TRAFFIC SAFETY Vehicular Conflict Points The existing access configuration results in over 100 vehicular conflict points The proposed access configuration for all the build alternatives will result in a 22% reduction in vehicular conflict points
EMERGENCY VEHICLE RESPONSE AND TRANSPORT All Build Alternatives will provide two lanes in each direction and wide paved outside shoulders Provides more refuge for vehicles to slow down and pull over for Emergency Service Providers All Build Alternatives will eliminate circuitous travel routes for Emergency Vehicle Response and Transport
DRAINAGE Impact on Storm Water and Drainage Avoidance of Pollutants in Blackberry Creek Storm Water Volume Impacts on Blackberry Creek (Flooding)
BEST MANAGEMENT PRACTICES (BMPs) What are BMPs? Improves Overall Water Quality Minimizes Soil Erosion Controls storm water runoff by capturing soil sediment and roadway pollutants BMP DESIGN PROCESS Select Preferred Alternative Complete Drainage Study and Identify BMPs Present Drainage Study at Public Hearing Further Design and Detail In Phase II Permits from Regulatory Agencies in Phase II
ENVIRONMENT Air Quality Noise Lighting Forest Forest Preserve Floodplains Waters of the US Wetlands
NOISE ANALYSIS What is a Noise Receptor? Noise Analysis Process 1. Identify Noise Receptor Locations 2. Determine Traffic Noise Level o Modeling o Validated by Field Monitoring 3. Traffic Noise Impact Identification 4. Traffic Noise Abatement Analysis
NOISE ANALYSIS FEASIBILITY AND REASONABLENESS POLICY FEASIBILITY Abatement must achieve at least 5dB(A) traffic noise reduction Abatement must be feasible to construct REASONABLENESS Generally, noise abatement cost must be <$30,000* per benefitted receptor Must achieve at least an 8 db(a) noise reduction at a benefited receptor * Adjustment factors can increase the allowable cost per benefited receptor
NOISE ANALYSIS Example Letter and Voting Form (May Occur During Next Phase)
LIGHT Interchange Lighting for Safety No High Mast Lighting All Ramps will have Light Poles IL 47 will have Lighting at Interchange IL 47 will have Transition Lighting from Interchange - Generally From Finley to Seavey Lighting Is A Local Cost Item Adjacent Rural Sections Do Not Have Lighting No Lighting Is Currently Planned on IL 47
