Disc Golf dangerous says Lafayette Neighbors
May 16th
Each speaker is allowed 5 minutes. Council will listen to everyone. If there are so many people that Council is unable to conduct their scheduled business, they may opt to convene another meeting in order to give everyone an opportunity to speak. Susan said this is totally up to Council and she cannot predict what they might do.
I put together a summary of ten main points why disc golf does not belong at Waneka Lake. Let me know if you have any additions or changes you think should be made.

Top Ten Reasons Why a Disc Golf Course Does Not Belong at Waneka Lake Park
1. It’s not what the majority of Lafayette citizens want.
According to the Lafayette Parks, Recreation, Open Space & Trails Master Plan Survey 2012, pages 27-31, Disc Golf ranked very low in the list of outdoor facilities that people want added, improved, or expanded. What ranked high on the list was “Additional park areas incorporating both native and manicured park type”. If you take a native park area and turn it into a disc golf course, you are taking away something people have told the city they want more of and giving the people something they have told the city they have little interest in.

2. It’s unlawful.
Lafayette Code of Ordinances, Chapter 80, Article 4
Sec. 80-59. Firearms and other missiles prohibited.
It shall be unlawful for any person to use, carry, or possess air rifles, spring guns, bow and arrows, slings, or any other forms of weapons; it shall further be unlawful to possess or use fireworks of any kind or nature; it shall further be unlawful to play golf or hit any golf balls.
(Ord. No. 1985-15, § 2, 6-4-85; Ord. No. 2005-8, § 1, 3-1-05)
Golf balls are included in the section on “prohibited missiles”. According to the city’s own code, it is unlawfull to hit golf balls at Waneka Lake Park. A golf disc is a “missile” that can cause every bit as much—if not more—damage to person and property than a golf ball and therefore should be prohibited from the park according to Lafayette’s Code of Ordinances.
3. It will result in environmental degradation.
Even the Professional Disc Golf Players Association acknowledges that a major concern with disc golf is soil erosion. The article “Assessing the Ecological Impact Due to Disc Golf” in the International Journal of Sport Management, Recreation & Tourism examines the ecological footprint of disc golf. In the study, three ecological markers were used as indicators of ecological degradation: soil erosion, soil compaction and density of vegetation cover. Results from the study conclude that disc golf significantly increases soil compaction, which yields greater soil erosion and a decrease in vegetation cover. Soil compaction due to human trampling is a problem with severe consequences. (See “Ecological Impact Due to Disc Golf” article attached to this email).
4. It’s potentially dangerous.
Discs used in disc golf are not the same as the Frisbees people use to play catch. They weigh 3 ½ times more than a golf ball. Even junior players can throw discs at 40MPH. More accomplished players can throw discs at speeds up to 75 and 80MPH. People hit by flying discs can be severely injured. Given where the current holes are placed, discs are going to be flying across heavily used trails. Even if disc golfers yell “fore” warnings, many people walk with headphones and won’t hear.

5. It is not compatible with the existing use of the park.
To help him design better disc golf courses at Boy Scout camps, Steve West created a statistical model of Boy Scout disc golf skills. He collected data on how far and how accurately Boy Scouts throw a disc. From this data, a model was developed for simulating large numbers of throws. His model can be used to replace guesses about where the discs will land with numbers based on data. The average Boy Scout routinely throws discs as much as 120 feet or more to the right or left of the fairway. If West’s scatter plots are superimposed on top of the proposed holes at the Waneka Lake Park, you will see that discs are going to cross well used trails, hit the Waneka Granary (which is on the Lafayette Register of Historic Places), land in streets and back yards.

6. Disc golfing requires a large amount of space devoted to a single use.
Regardless of the intent of the disc golf course creators, the nature of disc golf has the effect of discouraging non-golfers from using the area. What typically happens is that once a course is installed, players came to consider it as their own and show little patience for other casual users of the area. Since it makes sense that no one takes a casual walk through a regular golf course, they will most likely not, for their own safety, take a walk on a well-used disc golf course either.
7. Other cities are closing down disc golf courses due to safety and environmental degradation.

8. Sufficient time was not allowed for input from stakeholders.
A letter was sent out April 24 to people whose homes are adjacent to the course. The letter said the Recreation and Parks Departments were “in the process” of developing a disc golf course and that comments and questions would be accepted through May 9, giving the impression that the city was accepting input as to whether or not this disc golf course was a good idea. Yet at the very same time the letter went out, an announcement that a disc golf course “is coming” to Waneka Lake this summer was posted at the lake indicating that the installation of the course was a done deal and any comments or questions Parks and Rec receives in reality do not matter. No one other than the people living adjacent to the course was notified. Even though the Waneka Granary will undoubtedly be hit by flying discs, the Historical Society was not notified. The birding groups that frequent the park were not notified. Many people other than those living right by the park have a stake in how that land is used, yet no one was notified. This leaves the impression that this whole project is being rail-roaded through by the Recreation and Parks Departments.
9. The current disc golf course is underutilized and in disrepair.
The disc golf course at the Bob Burger Recreation Center fell into disuse and disrepair. If that course fell into disrepair, what is to prevent a course at Waneka Lake from falling into disrepair?
10. Because of growing safety concerns, disc golf course designers recommend disc golf courses be exclusive use only.
The following is a quote from Gregg Hosfeld who is:
3-time Professional Disc Golf Association World Champion
4-time United States Grand Master Disc Golf Champion
Disc Golf Hall of Fame inductee-Class of 1998
World Record Holder: “Most Courses Played” – 1,151
Disc Golf Design Group-Senior Designer
Co-founder World Champion Disc Golf Design
“I truly LOVE seeing the growing popularity of disc golf. I’ve been competing in tournaments since 1976 and giving lessons since the early 80s. I think it is a wonderful game for the entire family.
In the late 1970′s when disc golf was introduced, ALL flying discs were fairly lightweight and rounded edged. In other words, great for lofty flights and a game of throw & catch. As the game became more competitive and more geared toward sport, weight was added and then more streamlined aerodynamics were introduced. Over the years, these aerodynamics have been refined into some fast midrange discs and VERY fast “drivers”. Along with the “improvements” in disc technology, so must awareness of what that brings to the game. These high-tech discs, in the hands of a pro, can produce seemingly magically controlled flights. But in the hands of an inexperienced player, they can veer radically off the intended course. Very similar to a ’1-wood’ in standard golf in that regard. Simply put, “Faster” is harder to control. Same with cars, airplanes and anything hand propelled. I NEVER recommend these high-speed discs to newer players. Nor can I stop them.
With that in mind, we should consider that golf courses are designed to be exclusive-use areas; golf ONLY. Why? Those little balls are hard and they can hurt. Disc golf has been increasingly moving in the direction of exclusive-use areas, for the same reasons of safety. Any responsible disc golf course designer understands that. Unfortunately, many people in the parks & rec industry are only vaguely familiar with the game and have no reason to think that discs are any different now than in the 1970s.”
How Fast Is CUs Saarel?
May 2nd
Saarel, of Park City, Utah, arrived in Boulder already in the passing lane.
An engineering physics major with an interest (bet on it not being mild) in chemistry, he earned a 4.0 GPA in his first semester. And that, said Wetmore, was because “you can’t get a 5.0 . . . he finishes practices, takes his shoes off and goes to the library.”
When the Buffs leave the state for meets, as some will do this weekend for competitions in Austin, Texas and Stanford, Calif., Wetmore says Saarel “studies on the bus to the airport, studies at the airport and studies on the airplane. He’s a willing worker when he gets to practice and will do anything we ask of him. If he’s ever tired he doesn’t show it. He’s intense in practice, intense about his school work. I’d like to find a way for him to get a 3.999 (GPA) and relax a little, gear it down a little more.”
Saarel didn’t start running until he was a high school freshman, and that came at the urging of his sister, Emma, now a runner at Swarthmore (Pa.) College. After starting in cross country, he branched out to track, and in a short time reached a comfort level in both.
After winning the Utah State Class 3A cross country championship in the second-fastest time (14:56.7) ever run on the course, he was named the 2012 Gatorade Utah Cross Country Runner of the Year. Other accomplishments that year included first place at the Foot Locker West Regional and a second-place finish at the Nike Cross Nationals Southwest Regional championship. In track as a senior, he also won Utah state titles, with record times in the 800 (1:51.13) and the 1,600 meters (4:07.95).
Like all else he attempts, Saarel is into it in a big, big way at CU. Last fall, in his first cross country season for the Buffs, his finishes earned All-Pac-12 First Team, All-Mountain Region and All-America honors. In his first race for the Buffs – the NCAA Pre-Nationals – he was CU’s No. 2 scorer with a ninth-place finish. In the NCAA Championships, he finished eighth as the Buffs won their fourth NCAA team title since 2001. He became CU’s first true freshman since Billy Nelson to earn All-America recognition. Nelson, who finished 42nd that year (2002), now is one of Wetmore’s assistants.
Saarel is among 14 CU student-athletes who will compete on Sunday in the Payton Jordan Invitational at Stanford, while a pair of CU sprinters will run at the Longhorn Invitational on Saturday in Austin. Saarel is scheduled to run in the 5,000 meters on Sunday night.

CU develops solar toilet for third world use
Mar 13th
by CU-Boulder ready for India unveiling
A revolutionary University of Colorado Boulder toilet fueled by the sun that is being developed to help some of the 2.5 billion people around the world lacking safe and sustainable sanitation will be unveiled in India this month.
The self-contained, waterless toilet, designed and built using a $777,000 grant from the Bill & Melinda Gates Foundation, has the capability of heating human waste to a high enough temperature to sterilize human waste and create biochar, a highly porous charcoal, said project principal investigator Karl Linden, professor of environmental engineering. The biochar has a one-two punch in that it can be used to both increase crop yields and sequester carbon dioxide, a greenhouse gas.
The project is part of the Gates Foundation’s “Reinvent the Toilet Challenge,” an effort to develop a next-generation toilet that can be used to disinfect liquid and solid waste while generating useful end products, both in developing and developed nations, said Linden. Since the 2012 grant, Linden and his CU-Boulder team have received an additional $1 million from the Gates Foundation for the project, which includes a team of more than a dozen faculty, research professionals and students, many working full time on the effort.
According to the Gates Foundation, the awards recognize researchers who are developing ways to manage human waste that will help improve the health and lives of people around the world. Unsafe methods to capture and treat human waste result in serious health problems and death – food and water tainted with pathogens from fecal matter results in the deaths of roughly 700,000 children each year.
Linden’s team is one of 16 around the world funded by the Gates “Reinvent the Toilet Challenge” since 2011. All have shipped their inventions to Delhi, where they will be on display March 20-22 for scientists, engineers and dignitaries. Other institutional winners of the grants range from Caltech to Delft University of Technology in the Netherlands and the National University of Singapore.
The CU-Boulder invention consists of eight parabolic mirrors that focus concentrated sunlight to a spot no larger than a postage stamp on a quartz-glass rod connected to eight bundles of fiber-optic cables, each consisting of thousands of intertwined, fused fibers, said Linden. The energy generated by the sun and transferred to the fiber-optic cable system — similar in some ways to a data transmission line — can heat up the reaction chamber to over 600 degrees Fahrenheit to treat the waste material, disinfect pathogens in both feces and urine, and produce char.
“Biochar is a valuable material,” said Linden. “It has good water holding capacity and it can be used in agricultural areas to hold in nutrients and bring more stability to the soils.” A soil mixture containing 10 percent biochar can hold up to 50 percent more water and increase the availability of plant nutrients, he said. Additionally, the biochar can be burned as charcoal and provides energy comparable to that of commercial charcoal.
Linden is working closely with project co-investigators Professor R. Scott Summers of environmental engineering and Professor Alan Weimer chemical and biological engineering and a team of postdoctoral fellows, professionals, graduate students, undergraduates and a high school student.
“We are doing something that has never been done before,” said Linden. “While the idea of concentrating solar energy is not new, transmitting it flexibly to a customizable location via fiber-optic cables is the really unique aspect of this project.” The interdisciplinary project requires chemical engineers for heat transfer and solar energy work, environmental engineers for waste treatment and stabilization, mechanical engineers to build actuators and moving parts and electrical engineers to design control systems, Linden said.
Tests have shown that each of the eight fiber-optic cables can produce between 80 and 90 watts of energy, meaning the whole system can deliver up to 700 watts of energy into the reaction chamber, said Linden. In late December, tests at CU-Boulder showed the solar energy directed into the reaction chamber could easily boil water and effectively carbonize solid waste.
While the current toilet has been created to serve four to six people a day, a larger facility that could serve several households simultaneously is under design with the target of meeting a cost level of five cents a day per user set by the Gates Foundation. “We are continuously looking for ways to improve efficiency and lower costs,” he said.
“The great thing about the Gates Foundation is that they provide all of the teams with the resources they need,” Linden said. “The foundation is not looking for one toilet and one solution from one team. They are nurturing unique ideas and looking at what the individual teams bring overall to the knowledge base.”
Linden, who called the 16 teams a “family of researchers,” said the foundation has funded trips for CU-Boulder team members to collaborate with the other institutions in places like Switzerland, South Africa and North Carolina. “Instead of sink or swim funding, they want every team to succeed. In some ways we are like a small startup company, and it’s unlike any other project I have worked on during my career,” he said.
CU-Boulder team member Elizabeth Travis from Parker, Colo., who is working toward a master’s degree in the engineering college’s Mortenson Center in Engineering for Developing Communities, said her interest in water and hygiene made the Reinvent the Toilet project a good fit. “It is a really cool research project and a great team,” she said. “Everyone is very creative, patient and supportive, and there is a lot of innovation. It is exciting to learn from all of the team members.”
“We have a lot of excitement and energy on our team, and the Gates Foundation values that,” Linden said. “It is one thing to do research, another to screw on nuts and bolts and make something that can make a difference. To me, that’s the fun part, and the project is a nice fit for CU-Boulder because we have a high interest in developing countries and expertise in all of the renewable energy technologies as well as sanitation.”
The CU-Boulder team is now applying for phase two of the Gates Foundation Reinvent the Toilet grant to develop a field-worthy system to deploy in a developing country based on their current design, and assess other technologies that may enhance the toilet system, including the use of high-temperature fluids that can collect, retain and deliver heat.
