UPDATED: August 9, 2021

Work Underway Now

The Open Space Trail Crew is currently working on the project. For your safety, please pay attention to signs and closures.

Project Purpose

The purpose of the proposed project is to implement the MCOSD’s Road and Trail Management Plan (RTMP) to provide the public with a safe multi-use trail system to enhance the visitor experience, reduce the environmental impacts on sensitive resources by reducing sedimentation and erosion, and establish a sustainable system of roads and trails that meet design and management standards and would provide safe year-round access along the trail alignment.

Project Description Summary

The proposed project on the east side of Rush Creek Preserve would upgrade a hiking trail, realign a trail for multiuse, convert a trail segment from road to trail, improve equestrian trail access, and decommission a steep segment of trail to restore habitat. This proposed project was identified in 2017 during the collaborative Region 4 designation process. Features would include:

  • Upgrade an existing social trail to sustainable standards and designate it as hiking only;
  • Realign Blue Oak Trail for multiuse;
  • Decommission the steep road segment of Iron Gate Fire Road and restore habitat;
  • Convert the sustainable segment of Iron Gate Fire Road from road to trail;
  • Designate new trail for equestrians and hikers.

Project Objectives

Implementation of the proposed project would achieve the following project objectives:

  • Provide safe and sustainable year-round trail access to the Rush Creek Open Space Preserve;
  • Eliminate unsustainable social trails and road segments;
  • Enhance habitat quality;
  • Improve visitor access;
  • Reduce road and trail-related erosion;
  • Reduce trail density and habitat fragmentation.
