One Arroyo Trail Project

Project Description

The One Arroyo Trail project is a joint project between the City of Pasadena and One Arroyo Foundation. Identified as the initial phase of the Arroyo Seco Trail Project, the project involves various trail improvements along two critical linkages, referred to as the Upper Arroyo Trail Loop and Lower Arroyo Trail Loop located within the Arroyo Seco. The purpose of the project is to provide safer, more accessible, and more contiguous routes throughout the Arroyo Seco by rehabilitating existing trails through stabilization of deteriorated trail segments and improvements to trail features. The Upper Loop area includes approximately 2.2 miles of existing and proposed trails situated within the northern portion of the Central Arroyo Seco. The Lower Loop area includes approximately 1.6 miles of existing and proposed trails situated primarily in the Lower Arroyo Seco and within the southern portion of the Central Arroyo Seco. Attachment A shows the location of each loop.

Specifically, the scope of work for the project consists of the following: Trail out-slope grading and repair to drainage dips to improve and control storm water drainage; placement of rock armor base on some trail segments to provide better erosion control; placement of stone terracing and steps for steep slope trail areas; installation of small footbridges to allow easy and safe traversing for users; and installation of lodgepole fencing and stone retaining walls.
