The Town of Corte Madera is in the design phase of a project to rehabilitate the Redwood Highway Multi-Use Path between Wornum Drive and San Clemente Drive. The project will upgrade the existing path to a class I multi-use path with 8 feet of asphalt paved surface and 2 foot decomposed granite shoulders. Three new Americans with Disabilities Act (ADA) compliant curb ramps will be installed at all street crossings and the Town will be upgrading the Shorebird Marsh Viewpoint area with new benches and hot mix asphalt surfacing.
This project originated from requests from path users and the Bicycle Pedestrian Advisory Committee (BPAC) due to the poor condition of the path, numerous uplifted areas due to tree roots, and narrow bottleneck sections.
Project Schedule and Estimate
The project is scheduled to begin construction in September, 2020. The project must be constructed between September and February due to environmental restrictions in the area.
As of November, 2019, the preliminary project estimate was $1,000,000, the official engineer’s estimate is still in development.
Tree Removal and Landscaping Plan
The Town will be removing approximately 40 existing trees along Redwood Highway which are uplifting and damaging both the roadway and the pathway. The existing trees which include: Italians Stone Pines, Peruvian Pepper, Acacia, and Silver Dollar Gum Eucalyptus, are all foreign trees that have aggressive root systems and have outgrown their provided space in the vegetated strip between the street and path. Most of these tree species are considered fire prone according to the Central Marin Fire Authority Guidelines.
As part of the design scope, a certified arborist inspected all the trees on the project and determined that the work to replace the path would end up killing most of the trees due to cut roots. The 39 Crape Myrtle trees between Wornum Drive and Nordstroms are not damaging the asphalt and will remain.
In order to maintain the aesthetically pleasing nature of the bike path, the Town has hired WRA Environmental Consultants to create plans to install new irrigation and replant the vegetated strip next to the path with trees and shrubs that have the following traits:
Preferably native species
Aesthetically pleasing species that are planted in other parts of town
Drought resistant plants and trees
Small to medium size trees that will fit in allotted space with nonaggressive root systems
Species which can survive in subpar soil conditions
The table below shows the current choice of trees, shrubs, and grasses chosen by the landscape architect for the project.
