Whitelock Interchange FAQs

Why is the State Route 99 Whitelock Parkway Interchange needed?

The City determined that the transportation corridors of Elk Grove Boulevard and Grant Line Road would operate at unacceptable levels at the build-out of the City.  In an effort to reduce future congestion and accommodate development the City has designated a future interchange at Whitelock Parkway and SR 99.  The project is needed to help relieve current and future congestion in central and southern Elk Grove.

How will the proposed project impact Elk Grove Regional Park?

While it is still very early in the planning and design process to assess potential impacts, one of the City’s major project goals is to minimize impacts to Elk Grove Regional Park.  To that end, the City has decided to collaborate with a Stakeholder Representative Group (SRG) which is comprised of the Cosumnes Community Services District (CSD) and representatives from other community and regional organizations that can assist in providing important community and study area information as well as help to evaluate design considerations to fit the interchange within the context of the community.  A variety of concepts will be developed (including a concept that will keep the roadway out of the park) and evaluated to determine the preferred option.

How is the project funded, how much will it cost, and when will the project be completed?

The project is fully funded by the Elk Grove Roadway Fee at about $41.5 million.  This fee is paid by developers to mitigate the traffic impacts of new development. These fees will be paid over many years as new development in the area occurs.  Current revenues only allow for the preliminary design and environmental work at this time.  The funds needed to construct the project are not currently available and may not be for many years.   The City will seek State and Federal Grants that would allow for the construction to occur sooner.  It is possible the project could be completed within 5 to 10 years if funding for construction becomes available.

If you do not have funds to construct the project now, why are you starting the project now?

Development is now occurring on the west side of the project site. It can take more than 5 years to design and secure the needed approvals for a new interchange. The City needs to determine the size and shape of the interchange now to preserve the needed land, more precisely determine the costs, and plan for the interchange construction.  Additionally, the City will be more successful in obtaining grant funds for construction if the project is further developed.

When will there be a public meeting where we can view alternatives and make comments?

Public Works held a public meeting on Wednesday, October 29, 2014. Staff anticipates hosting another public meeting in Summer of 2016.

Future public meetings will be advertised here once they are scheduled.

Who can we contact at the City regarding this project?

The Project Manager for the City is Gary Grunwald.  He can be reached via email at ggrunwald@elkgrovecity.org or by phone at (916) 478-2236.  All questions and concerns are welcome.

When will a final design be selected and approved by the City?

The project is currently in the “pre-environmental review” phase which identifies potential alternatives; and develops a scope and schedule to deliver the environmental document.    Several design alternatives will need to be included as part of the environmental review process.  Once the environmental review and documentation phase is complete, then the City will approve the design.

Will pedestrians and bicycles have to cross traffic?

The bicycle and pedestrians will cross the on and off ramps at signalized intersections with cross walks, and then they will cross over East Stockton Boulevard on the bridge directly into the park.

What are the typical grades through the interchange?

The freeway grade is the same as the park; therefore, the crossing needs to climb to an elevation of 20-25 feet above the freeway to provide standard vertical clearances under the proposed bridge.  The Whitelock Parkway grade through the interchange will be 5% or less to meet the Americans with Disabilities Act requirements for pedestrian facilities.  The Ramp grades approaching the intersection will be between 5 and 7% to conform to the elevated intersections.

Will the dog park be impacted?

We are currently studying the options.  Based upon our initial evaluation we anticipate a portion of the dog park may need to be moved and reconfigured.

Does traffic stop on eastbound Whitelock Parkway to southbound SR99 when the bicycles and pedestrians need to cross?

We still need to perform traffic analysis for these concepts.  However, generally speaking, if the traffic analysis presents low volume of automobiles at this intersection, then bicycles and pedestrians could cross without a signal.  If traffic volumes were so large that pedestrians would have a difficult time crossing this ramp there would be a pedestrian push button and a signal added to the project.

Will the City engage the community throughout planning and design phase of the project?

Yes, the City will engage the public during the planning and design phases of the project.

How can members of the public provide their input?

The City has held one public meeting and expects to hold another public meeting in the Summer of 2016. The public will have opportunities to provide their input at these meetings.  In addition, the public may provide comments throughout the project’s process by sending emails to ggrunwald@elkgrovecity.org.  All public comments will be considered by the project team and documented and provided to the City Council as part of the formal project summaries. Lastly, members of the public will be notified for all formal presentations to the City’s Planning Commission and City Council.

Who are the Stakeholder Representative Group (SRG) members?

SRG members for the Whitelock Parkway Interchange project include a primary and alternate representative from Elk Grove-based organizations including:  Elk Grove Historical Society, City of Elk Grove Trails Committee, Elk Grove Regional Parks, City of Elk Grove Disability Advisory Committee, Elk Grove Bike Park, Cosumnes Community Services District, Elk Grove Youth Sports Association, EGYSA Girls Fast Pitch Softball League, Elk Grove Chamber of Commerce, and Glenbrooke Neighborhood Association.  In addition, the SRG includes representatives from interest-based regional organizations including: Sacramento Area Bicycle Advocates and Walk Sacramento.  Each member represents an organization that may be affected by the project’s outcome and/or can provide expertise to help create a community context sensitive project.

What is the role of the SRG?

The role of the SRG member is to attend and actively engage in small group work for three meetings over the next year to assist the project team in identifying community issues, concerns, needs and values.  In addition, SRG will assist in evaluating current and future transportation amenity needs and prioritization of proposed solutions.  Each SRG is responsible for representing his/her organization’s perspective and serving as the communication conduit between the project team and his/her organization.

Can the public attend the Stakeholder Representative Group meetings? 

SRG meetings are open to the public and members of the public may attend and observe.  Meeting summaries will be provided on the project website. On April 30th, the project team hosted the second meeting of three meetings with the Stakeholder Representative Group (SRG).

Will there be ongoing communication with the City Council?

Yes, City staff will provide updates to City Council as necessary.

Does the interchange connect State Route 99 to east and west Elk Grove?

No, the interchange will not provide access for cars on the east side of State Route 99 to the west side of town or a connection with State Route 99 from the east side. The interchange will only provide access to State Route 99 for west side travelers. Bicyclists and pedestrians will be able to cross SR 99 and directly access Elk Grove Regional Park.

Why is the City not looking at a full interchange at the south end of Elk Grove Park?

The City identified the future interchange at State Route 99 and Whitelock Parkway in the adopted General Plan after much planning work and environmental review. A southern location would not connect to the planned east west roadway corridors established through planned development in the General Plan and would not adequately address the traffic impacts created by the build-out of the General Plan.  Additionally, Caltrans requires interchanges to be spaced at least 1 mile apart.  Placing a full service interchange one mile north of Grant Line Road Interchange would have a severe impact to the south end of Elk Grove Park and the adjacent residential neighborhood.

Further, the City (and Sacramento County before incorporation) has made a number of land use decisions and approved various projects in and around the future Whitelock Parkway Interchange.  These projects were designed with the future interchange in mind at the planned location.  Relocation of the interchange to the south would have significant implications within four master planned areas and would conflict with several projects that are in or nearing construction.

Why is an eastern connection to Elk Grove-Florin Road or East Stockton Blvd. not being considered?

To make a connection to the east side of State Route 99 for vehicles would create a severe impact to Elk Grove Park.  Additionally, neither Elk Grove Florin Road nor East Stockton Blvd. were designed to accommodate the additional travel demand that would be generated with such a connection
