Ma Nature to dump on Front Range
Oct 24th
Colorado weather can be unpredictable. Recent warm temperatures are forecasted to change drastically and potentially drop several inches of snow on Wednesday, Oct. 26. The City of Boulder is doing everything it can to prepare for whatever winter might have in store.
Snow removal procedures on city streets
The city’s Public Works Department has snow crews on-call 24-hours a day, seven days a week to respond to changing weather conditions. During snowstorms, there are 16 plow trucks on Boulder streets. Six of them distribute a liquid deicer, four spreader trucks distribute traction materials, and seven can distribute either. Fifteen trucks drive predetermined routes while one “floater” responds to problem areas.
Plows push the snow to the center lane where space is available. If space is not available, the snow is pushed to the side of the street. A liquid deicer is used on both streets and bike paths.
The city also applies deicing agents to streets and bridges for ice and snow control. Streets may be pretreated before a storm to reduce the build-up of snow and ice, depending on weather conditions. The liquid deicer may also be applied throughout a storm to continue melting the snow pack. Spreader trucks put down a crystallized deicer and lightweight, porous rock for traction, where needed.
Snow removal on city streets depends on the amount of snow and length of the storm, time of day, temperature and traffic conditions. Because most snow melts within a day or two in Boulder’s sunny climate and because plowing costs would increase by 200 percent, the City of Boulder does not plow residential streets. Plowing residential streets also blocks driveways and parked cars.
Sidewalk snow removal information
The Boulder Police Department recently took over the enforcement of a number of city code violations from the Public Works Department, including enforcement of the sidewalk snow removal ordinance.
The Boulder Revised Code (8-2-13) states that owners, tenants and landlords must clear their sidewalks within 24 hours after the end of a snowfall. Residents will be responsible for checking with the National Weather Service for specific snow fall completion information. Failure to remove snow before the deadline may result in a summons and/or an abatement process.
Each property will receive only one warning per snow season before the abatement process begins. A warning does not have to be issued in order for a code enforcement officer to issue a summons. Abatement includes the use of a private snow removal contractor to clear the sidewalk; the property owner will be charged a $50 administrative fee along with the contractor’s fee for removing the snow.
If a summons is issued, the maximum fine is $1,000 and 90 days in jail as determined by a municipal judge. The fine for a first-time offense is $100.
For people who are physically unable to clear snow from their sidewalks, the ICEBUSTERS program may be able to pair them with someone who can do the work for them. Volunteers are needed for this program. To volunteer or learn more, please contact the Retired Senior Volunteer Program (RSVP) at 303-443-1933 or email richardvarnes@rsvp.org.

CU-Boulder, USCS to lead E-vehicle studies
Oct 17th
COLORADO SPRINGS, Colo. – University of Colorado Boulder faculty will join with University of Colorado Colorado Springs faculty to teach courses in the design and implementation of electric vehicle drivetrains to new and retraining engineers.
The U.S. Department of Energy recently provided a five-year $954,000 grant to UCCS for the development of courses to prepare engineers for careers in developing new technologies for vehicles having electric drivetrains. The master’s-level courses will be taught by both UCCS and CU Boulder faculty members with expertise in batteries, battery controls, and power electronics.
The courses will be available through distance learning technologies such as online courses and, possibly, CISCO Telepresence, in addition to traditional in-person classrooms, making them available to people nationwide.
“There are thousands of engineers who have either been displaced as the U.S. auto industry shifted or who have an interest in learning about creating vehicles of the future,” Greg Plett, professor, UCCS College of Engineering and Applied Science, said. “This program offers them the opportunity to retrain without relocating.”
Plett, the principal investigator on the project, has spent his career working with battery controls and has close relationships to many Colorado-based companies who manufacture batteries or their controls as well as large corporations such as General Motors. Plett is working with General Motors’ engineers on new methods for battery controls in future extended range electric vehicles, beyond the Chevy Volt.
The GATE Center of Excellence in Innovative Drivetrains in Electric Automotive Technology Education will provide students the opportunity to earn a graduate certificate in electric drivetrain technology by taking four courses in battery dynamics, battery controls, power electronics and detailed courses in adjustable alternating current drives. Plans also call for creating options for students in master’s of science in electrical engineering programs at UCCS and CU-Boulder to pursue specialization in fields such as battery controls, taught by UCCS faculty, and vehicle power electronics taught by CU-Boulder faculty members.
CU-Boulder faculty will build upon strengths of the Colorado Power Electronics Center research and education programs, including a highly successful Professional Certification in Power Electronics already offered online by the College of Engineering and Applied Science’s distance education program (http://cuengineeringonline.colorado.edu/)
“This program combines the strengths of the faculty of two CU campuses for the benefit of students,” Plett said.
Plett also believes the collaboration of faculty will lead to new research in battery technology. Battery life and power outputs have long been considered hindrances to the development of electric vehicles including cars, trucks and mass transit vehicles.
Plett envisions that fellowships to reduce the cost of the graduate coursework will be available with 30 to 40 students enrolled annually beginning with the fall 2012 semester.
Working with Plett will be Scott Trimboli, assistant professor, UCCS College of Engineering, and Regan Zane, associate professor, Department of Electrical, Computer, and Energy Engineering, CU-Boulder, and Dragan Maksimovic, professor, Department of Electrical, Computer, and Energy Engineering, CU-Boulder.
