CITY OF DENTON CITY COUNCIL
May 1, 2006
After determining that a quorum is present, the City Council of the City of Denton, Texas will
convene in a Special Called Work Session on Monday, May 1, 2006 at 11:30 a.m. in the Council
Work Session Room, 215 E. McKinney, Denton, Texas at which the following items will be
considered:
NOTE: A Work Session is used to explore matters of interest to one or more City Council
Members or the City Manager for the purpose of giving staff direction into whether or not such
matters should be placed on a future regular or special meeting of the Council for citizen input,
City Council deliberation and formal City action. At a Work Session, the City Council generally
receives informal and preliminary reports and information from City staff, officials, members of
City committees, and the individual or organization proposing council action, if invited by City
Council or City Manager to participate in the session. Participation by individuals and members
of organizations invited to speak ceases when the Mayor announces the session is being closed to
public input. Although Work Sessions are public , and citizens have a legal right to
attend, they are not public , so citizens are not allowed to participate in the session
unless invited to do so by the Mayor. Any citizen may supply to the City Council, prior to the
beginning of the session, a written report regarding the citizen?s opinion on the matter being
explored. Should the Council direct the matter be placed on a regular meeting agenda, the staff
will generally prepare a final report defining the proposed action, which will be made available
to all citizens prior to the regular meeting at which citizen input is sought. The purpose of this
procedure is to allow citizens attending the regular meeting the opportunity to hear the views of
their fellow citizens without having to attend two meetings.
1. Receive a report and hold a discussion regarding the Water, Wastewater, and Solid Waste
Forecasts.
2. Receive a report and discuss the issue of dumpsters located in the public right-of-way and
on public city sidewalks.
Following the completion of the Special Called Work Session, the City Council will convene in a
Closed Meeting to consider specific items listed below under the Closed Meeting section of this
agenda. The City Council reserves the right to adjourn into a Closed Meeting on any item on its
Open Meeting agenda consistent with Chapter 551 of the TEXAS GOVERNMENT CODE, as
amended, as set forth below.

AGENDA DATE: May 1, 2006
DEPARTMENT: Utilities Administration
CM: Howard Martin, 8232

SUBJECT
Receive a report and hold a discussion regarding the Water, Wastewater, and Solid Waste
Forecasts.
BACKGROUND
The City of Denton?s Utility Departments have prepared new forecast that will support
development of the FY 2007-2011 CIP?s, FY 2007 operating budgets, and other long-range
service requirements. The first phase of the forecast process involves gathering and analyzing
historical information to determine relationships between population, customers, production,
consumption or usage data. The next phase is to apply the historical trend data to future growth
assumptions, to include population projections and commercial/industrial activity and land use,
in order to determine future service requirements.
The City of Denton population projections are provided by the City?s Planning and Development
Department. This data is adjusted annually to reflect any changes necessary that may affect the
population estimates. The City of Denton Planning department growth rate projections are
generally used to project City of Denton population growth through the next 20 years.
Although Water, Wastewater, and Solid Waste each use the City of Denton population
projections as one factor in developing the forecast, each utility has its own distinct service area.
This results in different assumptions for the service area population and percent of population
actually served by an individual utility.
Exhibit I provides a summary of the Water utility forecast. The new Water forecast reflects only
minor changes from the previous forecast. Major points include the following:
Denton will need 100% of its raw water rights from Lake Ray Roberts and Lake Lewisville
in the 2012-2013 timeframe. Staff will continue to evaluate options from new sources of raw
water, including activation and renewalof the existing Dallas raw water contract.
Additional treatment plant capacity will also be needed in the 2012-2013 timeframe. The
current plan is to expand the Lake Ray Roberts treatment plant from 20 to 30 MGD. Based
on recent data, gallons per capita per day (gpcd) continue to be below 175 gpcd. The
reduction in per capita does not change the estimated 2012-2013 timeframe for the Lake Ray
Roberts treatment plant expansion.
Raw water supplies and treatment capacity are estimated to be sufficient to meet Denton?s
needs for approximately 7-8 years. However, significant improvements to the distribution
system will be needed to insure the additional treated water capacity can be delivered to the
ultimate customer.

Exhibit II provides a summary of the Wastewater utility forecast. The new Wastewater forecast
reflects only minor updates to the previous forecast. Significant points are as follows:
All projects mandated by EPA Administrative Orders in 1999 and 2001 related to wastewater
overflows are complete ahead of schedule.
Since completion of the additional influent raw wastewater pumping capacity at the Pecan
Creek Water Reclamation Plant and the infiltration/inflow related projects, there is
significant reduction in the number and volume of overflows in the wastewater collection
system during wet weather events.
The projected wastewater volumes thru 2025 show that additional wastewater treatment
capacity in the Hickory/Pecan/Cooper Creek Basins is needed by the year 2020. However,
the peak wet weather flows reaching the plant will exceed the raw influent wastewater
pumping capacity. Additional raw influent wastewater pumping capacity will be required at
the Pecan Creek plant to eliminate wet weather induced overflows in the collection system.
The in-house update of the wastewater collection system computer model shows the Hickory
Creek Pump Station serving the entire Hickory Creek Basin will be adequate for the
upcoming 5 year CIP horizon. This may change if the 3500-acre Cole Tract development
project starts selling homes within 2 years and undergoes accelerated development. Flow
monitoring in the Hickory Creek Interceptor and at the pumping station will provide data on
timing of the wastewater improvements in the Hickory Creek Basin.
Options for initiating wastewater service in the Clear Creek/Milam Creek Basin have been
developed. Implementation of one of these options will provide wastewater service in this
sewer basin and may move back the construction of the Clear Creek Water Reclamation
Plant to 2011-2012 time frame. Final resolution of Craver Ranch issues may alter the Clear
Creek Plant schedule.
The Solid Waste Department?s projections of municipal solid waste weights and volumes are
based on the projected population forecast using a waste generation rate of 5.9 pounds per person
per day. Current municipal solid waste projections are for the City to landfill approximately
112,010 tons of refuse during 2006 and 117,835 in 2007. The 2006 and 2007 projections are
based on the following sources of waste delivered to the landfill.
2006 2007
Residential 23,499 24,898
Commercial 79,248 83,210
Delivered 9,263 9,727
Total 112,010 117,835
The City?s landfill has a projected site life through the year 2040. The increased site life is based
on several assumptions:
The continued use of alternate daily cover will reduce the amount of soil applied used for
cover.
Reducing disposed waste volumes by continuing to divert materials from the landfill through
the City?s recycling programs.

The reduced airspace utilization requirement through the City?s implementation of anaerobic
bioreactor technology will allow the landfill to reclaim airspace. The airspace utilization rate
is based on 1,100-lbs/cubic yard.

SUBJECT
Receive a report, and discuss the issue of dumpsters located in the public right-of-way and on
public city sidewalks.
BACKGROUND
The Solid Waste Department has been working with many of Denton?s business owners over the
past several years to relocate dumpsters out of the City?s right-of-way (R-O-W) and off of the
City?s public sidewalks. In January 2004 there were approximately 490 dumpsters located in the
street and in the City?s right-of-way. Since September 2005, the Department has worked with
businesses and property owner?s seeking their cooperation in the relocation of these dumpsters
onto their property. We pointed out that their property appearance would be improved if the
dumpster was moved from the R-O-W and we showed the customers using side load containers
that they could reduce their solid waste service cost by converting to front load containers
located elsewhere on their property. The October 2005 inventory showed the number of
dumpsters in the street and right-of-way being reduced by 24% to 369.
The Department has exhausted it voluntary marketing ideas to move dumpsters from the R-O-W.
The remaining non-converted customer?s dumpsters can generally be categorized as follows:
Dumpsters that have the potential to be relocated onto the owner?s property, but the
owners are not receptive to the voluntary relocation idea.
Dumpsters that appear to have no inexpensive relocation alternative.
Dumpsters that are shared by more than one customer with no property owner wanting it
moved to their property.
Dumpsters in the downtown area that appear to have limited or no relocation alternative
on the customer?s property or in the proximity of their business.
Dumpsters with no apparent relocation alternative.
OPTIONS
City staff seeks direction from the City Council on the approach which they may prefer the staff
to take from this point forward. Possible options are:
Require all dumpsters to be relocated through a change in the Code.
Require dumpsters that have relocation potential to be moved. For those that do not have
relocation potential, assess a R-O-W usage fee.
Take no further action except upon change in ownership or property management, with
the Department continuing to seek voluntary relocation of dumpsters.
Other options that may be provided by City Council.
The staff will discuss possible incentives that may be offered to property owners to lessen the
impact of relocation.
PRIOR ACTION/REVIEW (Council, Boards, Commissions)
This issue was reviewed and discussed by the City Council at their meeting of September 13,
2005 and during earlier meetings over the previous year.
FISCAL INFORMATION
Recommendations on container locations can be accomplished within the departments existing
budget funding.
