Presentation Transcript

  1. Welcome to El Dorado Hills

  2. Goals of Presentation • Summarize growth, traffic, and road network stateaffecting planning in EDH- Especially where not easily evident from the perspectiveof Sacramento County and its cities • Focus in on implications for Connector alignmentin the El Dorado Hills area • Offer recommendations, including two conceptsto improve through traffic routing

  3. Topics for the Connector in EDH • Regional connections & through traffic • Demand for road network capacity (traffic volume) • Available road network capacity • Problems with through traffic on White Rock Road • Concepts foralternative Connector alignments

  4. El Dorado Hills as a “traffic lens” Between two regions • E/W through traffic limited to US 50 and Green Valley

  5. El Dorado Hills as a “traffic lens” Between two regions • E/W through traffic limited to US 50 and Green Valley • Very low arterial density in comparison with Sac County

  6. Road System Demand:population growth Actual EDH growth probably is closer to EDH 50% of County growth, not 88%. Data sets are based on different assumptions for housing occupancy.

  7. Population growth as% of 1999 base year population

  8. Demand for road system capacity:El Dorado County Population Growth Projections dating from the 2004 General Plan debate Actual Growth

  9. Planned road system capacity growthcompared to population growth Population estimates are for entire West Slope

  10. El Dorado Hills,the 2010 CDP …with a highlight over the County Line

  11. Existing EDHroad network

  12. FutureEDHroad networkadditionsas currently planned Silver Springs Silva Valley interchange Saratoga Country Club Connector Empire Ranch Road

  13. Existing traffic levels (2008) Average Daily Trips ± 2,500 30,000 25,000 20,000 15,000 10,000 5,000 Less than 2,500 68,000 61,000 93,000

  14. Traffic countchange ratechange depicted by colored markers, percent increase or percent decrease since 2004.Time range covered is lesswhere insufficient data exists +42% +122% +47% -21% New, then -9% +30% or more +20% to +30% +10% to +20% 0% to +10% -10% to 0% -20% to -10% -20% or more -27% +211% +36% New, then +16% New, then +15% +42% +138%

  16. Traffic count trendsAverage Daily Trips

  17. White Rock Corridor * An issue for regional Through traffic: Traffic Signals Likely later Likely later + 2 moreexisting signals Likely, Folsom SOI

  18. Connector/US 50 traffic balance in EDH & Folsom Which of these will be true? • The Connector will divert traffic from US 50 • US 50 will divert traffic from the Connector • US 50 and Connector traffic will be independent • Each may occur at different times Peak risk of congestion is in the afternoon peak period.Even with US 50 LOS F jams such as the one on the title slide, White Rock may be slower for through traffic.

  19. FutureEDH road network, currently planned

  20. Future EDH road network, Connector suggestion #1

  21. FutureEDH road network, Connector suggestion #2

  22. Alternative alignment concepts dismissed as unlikely to be viable • Direct diagonal connection for through traffic across Folsom SOI Not planned by City of Folsom, City is very unlikely to replan SOI land use and circulation • 2-mile tunnel below EDH for through traffic to bypass EDH surface streetsHighly unlikely to be economically feasible

  23. Recommendations • Keep regional through traffic off of White Rock Road in EDH – Growth in through traffic plus local traffic will be a problem for both. • Escalate joint planning among multiple agencies – especially for coordinated EDH/Folsom road network development . • Specifically review need for arterials/feeders west of the EDH Business Park, including the eastern Folsom SOI area. • In El Dorado County: Undertake substantial revision of planning to avoid future road network overloads Agencies: Connector JPA, El Dorado/Folsom JPA, City of Folsom, El Dorado County Transportation Commission, County of El Dorado, County of Sacramento, possibly Caltrans

  24. Not the end of traffic issues But nearly the exit for this presentation…

  25. Best wishes for choosing that ideal EDH alignment for The Connector!!!
