News Briefs

We're on the Web

As we go to press the District is on the verge of getting on the Web. We have a home page under design, which will be at: www.udfcd.org, and a bunch of e-mail addresses including:

Scott Tucker: lst@udfcd.org
Ben Urbonas: burbonas@udfcd.org
Dave Lloyd: dwl@udfcd.org
Bill DeGroot: bdegroot@udfcd.org
Kevin Stewart: kstewart@udfcd.org
Mark Hunter: mhunter@udfcd.org
Sandra Gonzalez: sandyg@udfcd.org

On our home page we hope to have some basic information about the District and the latest issue of Flood Hazard News (with color photos). If all goes well we may expand to include electronic files, like hydrology models, and our monument information.

District Wins Accounting Award

For the eighth year in a row the District has received a "Certificate of Achievement for Excellence in Financial Reporting" from the Government Finance Officers Association of the United States and Canada. The certificate is presented to government units whose comprehensive annual financial reports achieve the highest standards in government accounting and financial reporting.

Congratulations to Frank Dobbins, Chief of Finance and Accounting, for continuing this string of awards.

Projects Win Awards

Three projects which were sponsored in part by the Urban Drainage and Flood Control District won "Colorado's Best of 1996" awards from the Colorado Association of Stormwater and Floodplain Managers at its annual conference in Vail in September. The Outstanding Project of the Year was the Goose Creek flood control channel designed by Greenhorne & O'Mara, Inc. and funded by the City of Boulder and the District.

Stormwater Management Planning for Stapleton Redevelopment, sponsored by the District and the City and County of Denver, and completed by

McLaughlin Water Engineers, Ltd. and Wenk Associates, won an Honor Award for Outstanding Achievment.

Also winning an Honor Award was South Platte River Improvements - Confluence Park, sponsored by Denver and the District and designed by McLaughlin Water Engineers, Ltd. This project was featured in the cover story of the 1995 Flood Hazard News.

Bidtabs Program

The District has been utilizing and distributing the Bidtabs Program for seven years. It is continuously updated by the Design and Construction Program. The Bidtabs data contains bid unit price information on 113 District projects, and continues to grow.

This program is now widely distributed to consulting firms, contractors, and state and local government agencies, upon their request. Once you have requested the program, your name will be added to the Bidtabs User List, which allows you to receive any updated information.

The Bidtab information has been a very useful tool in estimating construction projects. The program can be run from DOS or Windows in a DOS shell. By March, the program will be provided in a Windows version. For more information contact Laura Garcia or Paul Hindman at (303) 455-6277.

Fifteen Years of Maintenance Costs

The maintenance program has completed its compilation of urban drainageway maintenance costs (first reported in Flood Hazard News last year). The result is a data base that can be used to show actual drainageway maintenance costs over the last 15 years for a variety of drainageway types.

Work records were analyzed going back to the beginning of the program in 1981. The types of maintenance work include mowing and debris pickups, local erosion repair, and major channel reconstruction. It should be noted that the mowing and debris pickups we do are on natural grass channels only. All our drainageway maintenance work is carried out through contracts with private contractors and consultants.

The database can be sorted in a variety of formats depending on the information that is desired. Listed below are a few examples of the output available from the database:

  1. The annual maintenance expenditure per mile for mowing and debris pickup on a particular type of drainageway, such as grass-lined, riprap lined, or grass-lined with a hardened trickle channel.
  2. The total maintenance expenditure on a particular drainageway for the period covered by the database.
  3. The annual maintenance expenditure per mile for any of the drainageways included in the database.
  4. The annual maintenance expenditure on a particular reach of a grass-lined drainageway with drop structures, including costs for structural repairs.
  5. The annual or total maintenance expenditure for all drainageways within a particular city or town.

At the end of each year's drainageway maintenance activities we will add that year's cost information to the data base. As the period of time covered by the data base expands the output will become more representative of the costs of long term drainageway maintenance.

Due to limited resources not every drainageway within the District has been included in this data base. Those drainageways with short or intermittent maintenance histories have not been entered.

Please feel free to call Mark Hunter at 303-455-6277 or fax 303-455-7880 to review the results from this data base. Questions regarding specific drainageway types and cross-sections are welcome.

Call For Papers:  NOVATECH 98

Every three years the French hold an international conference on the topic of urban stormwater technology. It is a major conference where one can learn much about the research and technology development in this field by the French and by others throughout the world. The next one, NOVATECH 98, will take place in late spring or late summer of 1998. The formal call for papers is available through Ben Urbonas and asks the authors to address any of the following: alternative technologies for stormwater management, control of combined stormwater/ wastewater effluent quality under wet-weather conditions, strategies and considerations for stormwater management at the city or town scale, and new design and management tools.

Of particular interest are the topics of physical modeling of original and innovative systems, non-traditional approaches to urban storm drainage, and techniques and tools for stormwater management in developing countries.
