Design Guidelines trail builder training and background check will be allowed to lead their own work parties and help maintain the park throughout the year, with permission of the Redmond Bike Park manager. Exhibit 3 - Technical Trail Features
1.4 Purpose and Scope of Design Guidelines The purpose of this document is to establish the design guidelines for the features within Redmond Bike Park. The design guidelines supplement the engineering plans and will help to ensure that the bicycle features are built in a responsible and sustainable manner while maximizing the riding experience for mountain bikers. The design guidelines provide a method for constructing the features described in the site plan layout, as shown in the following exhibit. Bike features such as jumps, bridges, log rides, and drops are called technical trail features (TTF). Conditions on the ground will determine the exact final trail routing and TTF locations. For that reason, approximate trail locations and routing will be shown on the map and may move slightly after construction begins. Trails will be routed and built according to the guidelines and specifications described in this document.

TTFs are not designed to specific engineering standards, as they have to be adjusted in the field based on environmental conditions, soil conditions, and flow between features. TTFs made of natural features such as soil and wood change constantly, requiring maintenance, and over time requiring reconstruction or changes. This document will serve the park during initial park development and in the future when community members or the City deem changes are necessary. This document will provide design guidelines for all of the Bridge in Whistler TTFs envisioned for the bike park. TTFs will be described by type and by skill level. These guidelines also provide some specifications on the types of materials needed, construction methods, and environmental responsibility.
