Welcome to El Dorado Hills

Goals of Presentation Summarize growth, traffic, and road network state affecting planning in EDH - Especially where not easily evident from the perspective of Sacramento County and its cities Focus in on implications for Connector alignment in the El Dorado Hills area Offer recommendations, including two concepts to 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

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

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

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.

Population growth as % of 1999 base year population

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

Planned road system capacity growth compared to population growth Population estimates are for entire West Slope

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

Existing EDH road network

Future EDH road network additions as currently planned Silva Valley interchange Empire Ranch Road Saratoga Silver Springs Country Club Connector

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 93,000 68,000 61,000

Traffic count change rate change depicted by colored markers, percent increase or percent decrease since Time range covered is less where insufficient data exists +30% or more +20% to +30% +10% to +20% 0% to +10% -10% to 0% -20% to -10% -20% or more +36% +42% New, then -9% New, then +16% +211% +47% +42% +122% +138% New, then +15% -21% -27%

White Rock Corridor 2008 traffic counts 6,408 8,523 13,708 9,328 29,228 24, or 2007 traffic counts 18,144 8,817

Traffic count trends Average Daily Trips

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

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 streets Highly 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

General Plan amendments, two examples: 2.Amend Policy TC-3B to prioritize road network improvement. In Community Regions place high priority on planning and building new roadways to provide multiple paths with good interconnection in the road network. Prioritize reduction of end-to-end travel time by reducing use of measures such as traffic signals. Existing policy TC-3b: The County shall consider Transportation Systems Management measures to increase the capacity of the existing road network prior to constructing new traffic lanes. Such measures may include traffic signal synchronization and additional turning lanes. 1.Adopt criteria for target LOS, not just minimum LOS. Consider target LOS B, for most areas, C for commercial areas such as Town Center.

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

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