Lafayette Station Site Improvement Project
Lafayette Station Site Improvements Project
1/10/2019 update: Progress continues to be made on the Lafayette Station Site Project with work crews putting the finishing touches on several improvements. Three new bio retention areas that will provide cleaner storm water runoff and help protect Happy Valley Creek are almost finished. Work is also moving forward on the installation of new signage as well as the planting of trees. The goal is to complete the project in early 2019.
Started in June 2017, construction work is taking place on the northwest parking lots of the Lafayette Station. The project is expected to be complete in early 2019.
Phase 1 includes temporary relocation of the ADA lot and intermodal zone. Permit parking will relocate to Lot C. Lot B will be temporarily closed and reopen at end of Phase 1.
Phase 2 includes temporary relocation of the permit lot adjacent to Happy Valley Rd.
Entrance to the north side of the station will remain open during construction during both phases.
During construction, you can use County Connection bus routes 6 and 25 to get to the station. For more information go to: https://countyconnection.com/maps-schedules/
We apologize for this inconvenience and appreciate your patience. We will continue to update all interested parties so please check back regularly.
The Lafayette Station Site Improvement project is a holistic and integrated effort combining intermodal improvements with storm water management improvements. This project consists of a redesign of the intermodal configurations of the station and installation of pervious pavers and rain gardens to capture, detain, and treat storm water runoff from the site’s parking and vehicular areas.

The project addresses traffic issues at the intermodal section and is making improvements to optimize traffic, lower congestion, and better align mode priorities. The following are the project goals.
- Meet ADA compliant parking and access requirements
- Improve vehicular queuing in the intermodal zone
- Improve pedestrian visibility and access to station
- Relocate and resize trash enclosures to improve functionality and access
- Provide ADA compliant connection from station to upper parking lot
- Provide bus stops for up to 2 full-size County Connection buses
- Replace and relocate bus shelter
- Improve vehicular circulation, visibility, and access from Deer Hill Road and Happy Valley Road
- Maintain bicycle amenities
- Provide LED lighting in the parking lots
Storm Water Management
- Provide effective storm water runoff capture and treatment through rain gardens and pervious pavers
- Satisfy MS4 permit requirements
Using the Power of Nature
One of the key improvements of the project is the installation of permeable pavers and rain gardens. These measures are known as low impact development (LID) and refer to systems and practices that use or mimic natural processes that result in infiltration, evapotranspiration or use of storm water to protect water quality and associated aquatic habitat. Older conventional designs create impervious surfaces and direct the runoff to storm water drain system without treatment. LID takes a different approach by viewing storm water as a resource rather than a waste product. LID promotes the natural movement of water within an ecosystem. The permeable pavers and rain gardens are designed to treat the runoff from the parking lot areas from potential storm water contaminants including hydrocarbons, sediments, heavy metals, trash and debris, oil and grease, and nutrients. Potential sources of this contamination include pavement wear, vehicular traffic, maintenance activities, tire wear, brake lining wear, motor oil and gasoline leaks, auto body rust, atmospheric deposition, and trash.

LID can help to maintain or restore a watershed’s hydrologic and ecological function. The rain gardens and permeable pavement from this project are helping to protect Lafayette’s Happy Valley Creek which culverts directly under the project parking lots and the station. The project also helps to protect the connected downstream waterways. Happy Valley Creek and its connected waterways are a part of the Walnut Creek Watershed which supports diverse riparian habitat and attract wildlife including Chinook and coho salmon and steelhead trout (Walnut Creek Watershed Council, February 2013).
