EnivroHorse Public Issue Paper: The Case for Saving
Trails from Budget Cuts (&Costs of Trails ATT. A)
By Adda Quinn
Mary Burns asked the County Trails Advisory Committee on February 11, 2003, to identify trails that could be closed since the Park and Recreation Department is facing a 12-20% budget cut by mid year. In a subsequent Park and Recreation Workshop on March 6, the magnitude of the problem was further defined. Staff reduction could mean reduction in trail maintenance capability. Trail users are very concerned that trails not be closed. We offer the following information to assist the County in priority setting.
Attachment A
The Cost of Building Trails
The cost to build one mile of trail can be highly variable. However, there IS a cost invested in trails that can often be quite high. In times of budgetary limitation for land managers, trails should not be items considered for "closure" due to lack of staffing. Trails should be considered as "facilities" or as some category immune to cuts. The following data was gathered and used in defense of threatened trail closures.

According to Midpeninsula Regional Open Space District planners, regular trail construction cost is estimated at $2.50 per foot; accessible trails ("Whole Access") at $7/foot. However, this figure includes only the cost of someone running trail construction equipment through on a normal, grassy site. These figures do not include staff/volunteer time, or significant vegetation removal, or construction of structures (such as bridges). Obtaining figures including these factors would depend upon the specific trail site and would require a planning study.

This is in response to your October 27 (1998) email regarding trail construction and maintenance costs. I apologize for the delay in responding-your questions had to go through a number of people in order to obtain information.
While we do not have a specific breakdown of the actual per-unit cost of trail construction, there is a "rule of thumb" rough estimate that we have used in the production of our Regional Open Space Study (map and information soon available): that amount is $4.50 per foot, or $27,360 per mile.
Likewise, we do not have actual dollar amounts per mile for trail maintenance; however, the overall budgeted maintenance expense for 1998-1999 is $1,335,909, which is about 45% of the total operations budget. That amount, however, is not broken down between trail maintenance and other maintenance activities.

Giving a meaningful cost estimate for trail construction/maintenance
Has always been fairly tricky given the wide variation in difficulty. For new construction, our rule of thumb has been $3.50-5.00/foot (the higher figure is for wider trail); for maintenance, $2.50-4.00/foot, depending on the type of work needed. These figures assume predominately, if not exclusively, volunteer hand labor, and 4-foot maximum width (about the limit for practical hand construction in steep terrain - in flat or gentle terrain, the same or lesser amount of effort could be used to construct up to
6-foot trail). The above costs reflect the aggregate administrative (i.e. overhead - in our case, relatively high) and actual field costs (low), but not necessarily inclusive of materials such as retaining structures, rock, etc. Any time materials are major component, costs rise dramatically.
Given all that, a conservative range for 1 mile of new construction
might be $18,480-26,480, while maintenance (assuming extensive maintenance along the whole width) would be $13,200-21,120. I believe commercial rates are typically within that range, although I would have to check around for current charges.
I should note that some time ago, the Trail Center changed the costing
Model to a per-workday cost, given the high variability of our projects. Under this model, we estimate $1,250/workday under the assumption that we can build approximately 350 feet per day on 3-3.5 foot wide trail. Our costs might be higher for 4+ foot wide trail (on the order of $1,600/workday), depending on the conditions. Sometimes this means that our per-foot cost is quite high, while other times, low. It works out to a little over $3.50/foot, though.

November 25, 1998 email from Peter Donohue to J. Franklin Sorba
Here are some numbers from BLM, USFS and Sutter Equipment (makers of the Sweco 480):
Hand Labor.......$6970 to $34,850/mile
Note: Easy to hard (1000 to 200 ft./day) based on a 10 man crew with a supervisor.
Backhoe/Excavator.....$2,200 to $11,000/mile
Note: Easy to hard (1500 to 300 ft./day) based upon a 5 man crew plus operator.
Sweco 480 (Rent)......$320 to $1,710/mile
Note: Easy to hard (8000 to 1500 ft./day) based upon operator and 1 laborer.
These estimates are based upon brushing/grubbing, tread construction, bank stabilization and some drainage feature construction. Obviously there are a lot of variables in these cost estimates.
Hope this helps a little!

This varies so much that I've never even tried to put together a figure. Believe it or not, but an excellent source from DuPage County (Chicago suburban area where I used to live) says the figure for their trails is now $80,000 per mile! However, there's a plan to upgrade trails in the area were I live that will do 35 miles for less than $100,000. The type of use, topography, soils, number of water and street crossings, etc. make this number swing from a low of "manual labor with shovels on acquired land" to a high of "expensive acquisition and built by government."

The major environmental damage done by trails is cutting of an initial trail. After that, maintenance is needed, but there is usually very little environmental impact from a cut trail that has proper drainage.
