Project Summary
Gateway Off-Road Cyclists (GORC) is proposing to build several skills development feature of various challenge levels located tangent to existing trails in Klondike Park. We request permission to build four structures:
(Note: Structures are numbered in sequence as if one were to ride from the shower house to the Powerline, Donjo's, Stripmine and then Donkey Kong trails.)

Structure 1: A “plank-bridge”, raised plank type structure over the sand pit south of the shower building at the beginning of the Power Line trail. Structure 2: Two to three small “drop-offs” of varying height (1-3‟) to be built on the side of a

declining slope on the Power Line trail near the start of the Donjo's trail. Structure 3: Two counterweighted teeter-totters approximately 18” in height near the base of the Donjo's trail. Structure 4: A plank structure of varying width from 18”-2‟ with rolling humps located towards the end of the Donkey Kong loop after the rock faced descent.

Our primary goal is to create a safe yet challenging environment of structures of varying difficulty levels that foster rider confidence, and are conducive to the further enjoyment of new and experienced riders alike. In addition, we aim to create durable structures that blend into the environment by being built with natural materials such as local rocks and trees(deadfall hardwoods only) wherever possible.

Detailed Designs:
1) Plank-bridges: A uni-directional “plank-bridge” would be placed over the sandpit with optional, narrow sections branching off in either direction. The plank-bridge would be approximately 32" wide, 6” high and span the length of the pit. The plank-bridge would be placed down the center of the sand pit. The narrow sections would fork off of the middle of the plank-bridge via a narrower (6") plank-bridge. Building materials would consist of treated 4x4 anchors attached to either split, fallen trees, treated and composite lumber. Structure would be built on-site.


2) Two or three drop-offs would be built at the top of a small slope ranging in heights from 1‟ to 3‟. As these will be dropoffs to a slope rather than drop-offs to flat ground, riders will enjoy a smoother landing zone that is isolated from the existing trail. These structures would be approximately three feet in length and would be built at the top of the slope. Each structure would have a square edge and would be placed tangent to the slope allowing a natural roll off of the edge of the structure. An adequately sized area has been located where the Powerline and Donjo's trail meet. Approximately 100‟ of new trail will need to be built approaching the structure and approximately 50‟ of new trail would need to be built after the structure to merge safely with the existing trail. This would be a one way feature but can be easily ridden in a loop. Building materials could consist of nearby rocks and mortar ,treated and composite lumber. This structure could be built off-site and assembled on the trail if it is decided that the structure will be built solely from treated lumber.


3) Two counterweighted teeter-totters would be built near the beginning of Donjo's trail. Each teeter-totter would be approximately 18” high at its center and approximately 16‟ in length. Each teeter-totter would be ridden in only one direction as they would be counterweighted to automatically return to their original position. Approximately 40‟ of new trail would need to be built on each side of the feature. Building materials would be a base of treated lumber with the possibility of using split logs or composite lumber as the riding surface. These structures would be built off-site and assembled on the trail.

4) A plank-bridge feature would be built at the base of the Donkey Kong trail immediately after the rock faced descent. This structure would be approximately 24” wide and 12” high. The plank-bridge would contain a slightly banked turn as well as several “bumps” to provide a roller coaster effect. Approximately 100 yards of new trail would be created to utilize the feature. The new trail section would start approximately


20 yards from the base of the descent and connect at the end of the existing trail. In addition, a new trail section will be added along the fence on the west side of the existing trail to create a loop allowing the feature to be ridden without navigating the Donkey Kong drop and rock descent. Building materials would be a base of treated lumber with the possibility of using split logs or composite lumber as the riding surface. This structure would be assembled onsite and assembled on-site.

Volunteer labor will be provided by GORC to construct, install and maintain all features. GORC will pursue grant funding to bear the full material cost.

Risk Management:
GORC's Risk Management policy covers several aspects of trail design, trail construction, maintenance and trail use.


Design: GORC will utilize established standards for the construction of trail features. These standards are based on IMBA, Peoria Area Mountain Bike Association (PAMBA), and the North Shore Mountain Bike Association (NSMBA). They include construction standards for man-made features, fall-zone specifications, and entry/exit criteria on trail features. These all combine to create a safe environment for progression from beginner to expert. Construction: GORC will provide insurance liability insurance of $2 million to cover all volunteers working on the construction and assembly of skill structures. Maintenance: GORC will practice a reasonable inspection interval, as well as monitoring by trail users who may communicate with the club through our website. This will enable us to monitor and remedy any potential maintenance issues early. Trail Use: Trail users are accepting a degree of risk by riding bicycles off-road, the idea behind GORC's risk management plan will be merely to make the level of risk very clear to all riders. To do this we'll employ the following techniques: Signage, Progression, and Fall Zones. Signage will be placed at the beginning of each feature to warn riders of potential danger. Varying skill levels will allow for riders to take a progressive approach to the features. Each feature‟s skill level has been chosen to match the general rider skill for each trail section; harder features are placed on harder trails. All structures will have open "fall zones" around each obstacle. A "fall zone" is the area adjacent to a technical trail feature, which provides a clear landing for a rider who has failed to negotiate the obstacle.


Conclusion: GORC is pleased to offer options to broaden the appeal of Klondike park for mountain bike users. We‟re eager to pursue the items listed in this proposal and other similar opportunities as they become available. This proposal is intended as a „broad-brush‟ to get concurrence from the County Parks Department on the concept of man-made trail structures in the parks. We will work in the same manner as always with layout/concepts presented for approval and construction under the authority of St. Charles County Parks. It is anticipated that this proposal will generate some discussion on these matters, and we would welcome any questions/discussion to insure expectations are met. Thank you for the opportunity to present this option.
