Welcome to El Dorado Hills

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

Topics for the Connector in EDH

• Regional connections & through traffic

• Demand for road network capacity (traffic volume)

• Problems with through traffic on White Rock Road

• Available road network capacity

• Concepts for alternative Connector alignments

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

Connector/US 50 traffic balance in EDH & Folsom

• 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

Which of these will be true?

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.

Future EDH road network, currently planned

Future EDH road network, Connector suggestion #1

Future EDH road network, Connector suggestion #2

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

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

Not the end of traffic issuesBut nearly the exit for this presentation…

Best wishes forchoosing that idealEDH alignment forThe Connector!!!
