controls, plat applications, annexation plans, development agreements,
annexation agreements, service plans, utility service, and legal issues
implicated by alternative proposals advanced by individuals owning
property within the proposed annexation area. A public discussion of

nd
NOTE: A 2 Tuesday 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
nd
deliberation and formal City action. At a 2 Tuesday 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
nd
ceases when the Mayor announces the session is being closed to public input. Although 2 Tuesday
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, hold a discussion and give staff direction regarding strategies for
maintaining and revitalizing neighborhoods.
2. Receive a report, hold a discussion and provide staff direction concerning a Lawn and
Landscape Irrigation and Water Waste Ordinance.
3. Receive a report and hold a discussion regarding the Water, Wastewater, and Solid Waste
Forecasts.

SUBJECT
Receive a report, hold a discussion and give staff direction regarding strategies for maintaining
and revitalizing neighborhoods.
BACKGROUND
The City Council has been considering strategies for revitalizing neighborhoods since the fall of
2004. The Council has been interested in pursuing methods to improve the quality of housing
and to affect the ratio of single family to multi-family units. Since then Council has directed
staff to research and review methods and programs to achieve Council?s goal of improving
Denton?s housing. To this end, in August 2005 Council adopted a comprehensive Multi-Family
Residential Standards ordinance.
The Multi-Family Residential Standards ordinance amended the Development Code by
permitting multi-family developments under the following conditions: with a Specific Use
Permit; or as part of a Mixed Use Development; or as part of a Master Plan Development,
existing; or if the development received zoning approval allowing multi-family use within one
year of the effective date of ordinance; or if allowed by a City Council approved neighborhood
(small area) plan. As well, the ordinance made provisions for restrictions that include a
development agreement and standards that establish a minimum level of development.
In February 2006 Council directed staff to proceed with further strategies for revitalizing
neighborhoods. In response the staff has prepared the following report. This report identifies
possible policy and code changes to revitalize Denton neighborhoods. These possible policy and
code changes include: adoption of the International Property Maintenance Code; conduct a
property maintenance survey; establish a rental inspection program; and process for upgrading
substandard housing. Concurrent with these policy and code changes are recommendations for
Comprehensive Plan amendments, land use issues, and Fair Housing Standards issues.
I. International Property Maintenance Code (IPMC)
The IPMC will establish minimum structure/premises maintenance standards for the City of
Denton. This review of the IPMC is a continuation of the comprehensive review of ordinances,
procedures and programs related to property appearance and code enforcement.
Proposed Ordinance
On February 14, 2006, the City Council received a report from staff on the IPMC. At that
meeting, Council directed staff to provide a more detailed comparative analysis of the IPMC
with existing City of Denton codes pertaining to building and property maintenance. The
purpose of the analysis is to determine if the City?s codes are consistent with the IPMC and what
gaps, if any, exist in the City?s codes or the IPMC. Attached for your review is the code
comparison (Exhibit 1).
Three components are combined in the comparative analysis:
1. Comparison between the IPMC and the City of Denton, Code of Ordinances and Denton
Development Code
2. Issues addressed in the Denton Development Code and the Code of Ordinances that are
not addressed in the IPMC
3. Additional provisions to be considered not currently considered in either the IPMC or the
Denton Code of Ordinances.
The IPMC will establish the minimum standard for property maintenance and serves as the
baseline tool for Code Enforcement and Building Inspection to address existing structures and
premises. As a preventative tool, the IPMC will, in the long-term, aid in stabilizing and
improving property values by correcting code issues at a much earlier stage. The enforcement of
the IPMC should prevent more significant and costly repairs and rehabilitation, that sometimes
occur at the city?s expense.
Recommendation
Staff recommendation is to move forward with the following process to adopt the IPMC.
Ordinance Adoption Schedule & Process
Public Input and Education
The Neighborhood Services Division will schedule two public hearings related to the IPMC
adoption. Both meetings will be publicized in the local newspaper and direct notification will be
provided to stakeholders and organizations likely to be impacted by this change. Copies of the
comparative analysis will be available for review and staff will review the document in detail.
The proposed schedule and process for adoption of the IPMC is as follows:
May 4, 2006 Public Meeting at Denia Recreation Center
May 15, 2006 Public Meeting at North Lakes Recreation Center
May 18, 2006 Construction Advisory and Appeals Board
May 24, 2006 Planning & Zoning Work Session
June 6, 2006 Planning & Zoning Public Hearing
June 20, 2006 Planning & Zoning Recommendation to Council
July 18, 2006 City Council Work Session
August 1, 2006 City Council Regular Session
Resource Information
To provide Code Enforcement service at the same level of other Metroplex cities, a survey was
completed of 11 other municipalities. This survey compared the number of Code officers to
population and square miles served.
Metroplex average 1 officer per 4.62 square miles
Denton average 1 officer per 12.41 square miles
10 additional Code Officers needed to meet Metroplex average for square miles served
Metroplex average 1 officer per 12,100 population served
Denton average 1 officer per 16,924 population served
2 additional officers needed to meet Metroplex average for population served
A supplemental package for two additional Code Enforcement Officers including equipment and
training needs was submitted for consideration in the FY 2006-07 budget proposal.
FY 2006-07 total = $172,726
II. Property Assessment Survey
To establish a baseline of information regarding existing property conditions, it is recommended
that a property assessment survey be completed. Staff has identified two cities that have recently
completed similar surveys to determine the scope, time frame and cost of this type of study.
Exhibit 2 is a table summarizing the information gathered.
In general, cities determine the assessment criteria for the surveys. On average, cities select up
to 10 items to be evaluated. The surveys can include assessments of the exterior of structures,
including accessory buildings and fences, city infrastructure on or near the property (sidewalks,
curb and gutter), and nuisance violations such as tall grass and weeds, yard parking, and trash
and debris of single-family, multi-family and commercial properties. Denton has approximately
22,000 single-family properties and 400 multi-family complexes.
The assessments are conducted as windshield surveys and are performed by two people: one
driver and one surveyor. Properties are assessed and scored based on what is visible from the
roadway. Cities supply these firms with GIS maps of developed parcels with platted lots. The
assessment findings are returned to the cities in GIS format.
Typically, properties are scored on a scale of 1 to 4 based on condition.
1 Meets Code
2 Minor Code Violation(s)
3 Major Code Violation(s)
4 Dilapidated Condition
In addition to providing an accurate baseline of information on existing property conditions
throughout the city, this information will allow staff to establish performance measures to more
accurately track code compliance citywide and productivity.
Survey Development Schedule & Process
May 1, 2006 Advertise RFP for contract professional services
June 5, 2006 Interview qualified proposals & select survey consultant
June 20, 2006 Contract considered by City Council
Nov. 30, 2006 Survey Completed
Recommendation
Identify funding and develop RFP for contract professional services for a Property Assessment
Survey.
Resource Information
Based on information provided from other cities, it is estimated that a consultant would charge
approximately $3.50 per parcel (structure) for a survey. With 22,000 single-family structures
and 400 multi-family complexes (approx. 800 buildings) in Denton, a rough estimate for this
survey would be $80,000 - $100,000.
III. Rental Inspection Program
The purpose of establishing a rental inspection program is to aid in maintaining and/or increasing
property values and neighborhood desirability by requiring minimum standards of cleanliness,
property maintenance, and structural integrity of rental units and their premises. Rental
inspection programs work to ensure that rental structures and their premises are safe and clean
for habitation. Inspection programs aid in reversing neighborhood decline, and reclaim and
restore older established communities while ensuring that property values and quality of life are
maintained in newly developed areas.
Inspections would include minimum structural standards related to plumbing and sewage
disposal, electrical wiring, foundation and roof condition, existence of window screen, as well as
standards related to unsanitary conditions such as the presence of rodents, insects, trash, junked
vehicles, and tall grass and weeds.
In Denton, Code Enforcement officers would focus on identifying and inspecting the interiors
and exteriors of single-family and multi-family rental properties. Officers would work with
owners and management companies to bring properties into compliance with City codes.
Substandard properties that are not brought up to code would be placed on a substandard
property list for future disposition.
Multi-Family Licensing and Inspection Program
This program would consist of the annual licensing and inspection of unoccupied multi-family
(MF) properties. It is expected that all exteriors and up to 10% of interiors would be inspected
annually. A letter of advance notice would be sent to the complex to schedule the annual
inspection. Occupied units are only inspected upon tenant request.
The annual licensing fee would be $12.60 per unit. There is no charge for the initial inspection
or the first re-inspection. A fee of $20 for each unremediated violation, not to exceed $40 per
unit, would be charged for each re-inspection after the first re-inspection.
Estimated annual revenue generated from these fees totals $231,895.
Implementation of this program to inspect the 400 complexes in Denton would require the
addition of four Code Enforcement officers and associated vehicles, equipment and office costs.
Single-Family Certificate of Occupancy Renewal Program
This program is a Certificate of Occupancy (CO) renewal and does not have a registration
component. Internal and external inspections would occur with a change of tenancy. The CO
would be issued to the owner.
Fees for this program would be $12.60 per year for single-family rentals, and $25.20 per year for
duplex rentals. Estimated annual revenue generated from these fees total $69,300.
Implementation of this program would require the addition of two Code Enforcement officers
and associated vehicle, equipment and office costs.
Program Development Schedule & Process
August 1, 2006 Adopt inspection provisions in the IPMC
September 2006 Develop inspection program procedures
October 2006 Begin hiring of Code Enforcement officers if positions approved
Recommendation
Submit supplemental packages for inspection programs for consideration in FY 2006-07 budget
process.
Resource Information
The net expense for a Multi-Family program would total $52,058 in FY 2006-07, and the net
expense for a Single-Family program would total $91,164 in FY 2006-07. These totals include
some one-time expenses for vehicles and equipment.
IV. Substandard Housing
At the completion of the property assessment survey, staff will evaluate the information and
develop a strategy to begin bringing violations into compliance and developing a prioritized list
of substandard structures to process for demolition. Prioritization would be based on conditions
that most endanger the life, limb, health, property, safety or welfare of the public or the
occupants of the structure.
Code Enforcement officers would begin working individual property cases as prioritized.
Structures identified for demolition would follow the existing process as detailed in Chapter 28
of the Code of Ordinances. This process is determined by the Texas Local Government Code
and meets the minimum requirements of that Code. Attached for your information is a table
detailing the cost and time involved in moving one structure through the demolition process.
Due to the political sensitivity of the demolition issue and the resources required to administer
the process, the City of Denton has not been aggressive in pursuing the demolition of structures.
Demolition funding through CDBG Program
Demolition of substandard buildings is an eligible activity under the Community Development
Block Grant (CDBG) program. The City of Denton has used CDBG funds for this purpose since
1984. In the past five years, 27single-family structures have been demolished under the
program. The average cost for the demolition of a single-family structure during this period was
approximately $3,200, however, staff has indicated that the current cost would be closer to
$5,000 per unit. The City of Denton currently has CDBG funding of $74,970 set aside for the
Demolition Program.
The City?s program targets vacant, substandard structures that have either been condemned by
the Construction Advisory and Appeals Board or requested to be demolished by a low-income
property owner. CDBG funds have not been used to demolish structures that were recently
occupied due to relocation requirements enforced by the U.S. Department of Housing and Urban
Development. These requirements entail payment of relocation costs and rental assistance to the
relocated household. If the relocated family is low-income, rental assistance must be provided
for a five-year period.
Implementation Schedule & Process
The existing substandard housing program is administered in the Building Inspection office as an
ancillary service. Implementation of this program beyond the current complaint-driven system
will require additional resources.
August 1, 2006 Adopt substandard housing provisions in the IPMC
October 2006 Begin hiring of Building Inspectors if positions approved.
Recommendation
Submit a supplemental package for consideration in the FY 2006-07 budget process.
Resource Information
A supplemental package for 2 additional staff including equipment, training needs and
demolition dollars was submitted for consideration in the FY 2006-07 budget proposal.
FY 2006-07 total = $235,464
OPTIONS
Direct staff to proceed with the proposed recommendations as deemed appropriate.
Direct staff to make changes and/or eliminate recommendations as deemed appropriate.

SUBJECT
Receive a report, hold a discussion and provide staff direction concerning a Lawn and Landscape
Irrigation and Water Waste Ordinance.
BACKGROUND
On April 19, 2005, the City of Denton updated its Water Conservation and Drought Contingency
Plan (the ?Plan?) as required by the Texas Commission on Environmental Quality. The Plan was
updated to comply with a series of bills passed to fulfill a statewide water conservation initiative
th
mandated in 2003 by the 78 Texas Legislature. A comprehensive description of this initiative
and Denton?s 2005 update is provided in Exhibit 2 and Exhibit 3. Perhaps the most notable of the
2003 water conservation bills is HB 2660, which requires five and ten-year water savings goals
in water conservation plans. For municipal water providers, the State Water Conservation Task
Force suggests a minimum annual reduction of one percent in total per-capita, based on a five-
year rolling average, until a per-capita of 140 or less is achieved. Denton?s five and ten-year
goals were a reduction of 9 gallons per day per-capita to 180 per-capita by 2009 and 18 gallons
per day per-capita to 171 per-capita by 2014. In order to comply with these requirements and
meet the established goals, Denton?s Plan calls for the continued implementation of Denton?s
ongoing conservation effort (Exhibit 3) along with both the moderate growth of Denton?s
effluent reuse program and the implementation of a lawn and landscape irrigation ordinance.
A lawn and landscape ordinance is intended to minimize waste in landscape irrigation. In North
Central Texas, Dallas, Arlington, Carrollton, Frisco, and Allen all have similar forms of a lawn
and landscape irrigation ordinance; Fort Worth is in the process of implementing an ordinance
this spring. Dallas? effort to help minimize water waste through an irrigation ordinance began in
2001 and since then has issued 1,491 warnings and 12 citations. Dallas enforces their ordinance
through their Code Enforcement Division. Arlington implemented their ordinance in 2004 and
enforces their ordinance through both their Water Utility staff and Neighborhood Services
Division (Code Enforcement) and, to date, have not had to issue any fines. Frisco and Carrollton
implemented their ordinances last year. Both cities enforce their programs entirely through their
Water Utility departments and neither has had to issue fines (Carrollton) or terminate service
(Frisco). Based on personnel interviews with staff members of the aforementioned cities, the
common thread is that generally the enforcement of the ordinance is mostly an educational
exercise; outside of a very few difficult customers, implementation and enforcement has not been
overly problematic.
1
Proposed Ordinance
According to Denton?s Plan, the ordinance was to be implemented in 2007, with an educational
program preceding it in 2006. However, due to the public?s awareness of local water supplies
and water conservation issues brought about by the current drought, along with the potential for
the drought to persist throughout the summer, staff suggested implementing the ordinance in
2006 (Exhibit 4). Feedback from Council members indicated that it would be prudent to
implement the ordinance this year, while potentially in a drought and at a time when there is a
high awareness of water conservation. The ordinance being proposed is based on practical,
common sense conservation measures that are consistent with other cities in the region and
includes the following elements (see draft ordinance, Exhibit 1):
Prohibition of outdoor watering with sprinklers from 10:00 a.m. to 6:00 p.m. every day
from June 1 through September 30. (Watering with hand-held hoses, soaker hoses, or
containers is allowed.)
Requirement that all new irrigation systems include rain and freeze sensors.
Requirement that all new irrigation systems be in compliance with state design and
installation regulations (Texas Administrative Code Title 30, Part 1, Chapter 344).
Prohibition of design, operation, or maintenance of irrigation systems that excessively
water impervious areas, or generate excessive runoff from over watering, such that a
constant stream of water overflows onto a street or drainage area.
Prohibition of use of poorly maintained sprinkler systems that waste water (broken or
improperly working heads).
Prohibition of outdoor watering during any form of precipitation.
Enforcement of the ordinance by a system of warnings followed by fines for continued or
repeat violators.
In addition to the requirements related to irrigation, staff is also proposing a water waste
component in the ordinance. The State Water Conservation Implementation Task Force was
created to fulfill the mandate of the legislation resulting from the 2003 water conservation bills.
The Task Force was assigned several tasks, one of which included identifying, evaluating, and
selecting Best Management Practices (BMPs) for municipal water uses. Prohibition of wasting
water was among the Task Force?s suggested BMPs. Staff is proposing to include the following
component in the ordinance:
Prohibition of leaking outside faucets, leaks on customer service lines, and excessive
leakage of interior plumbing
Staff also anticipates there may be special cases where there is an extreme hardship in meeting
ordinance requirements. Staff will evaluate those needs on a case-by-case basis and, if
necessary, provide relief according to the requirements outlined in the Variance section of the
ordinance.
Implementation
Staff is proposing to implement enforcement of the ordinance through both Utility personnel and
the city?s existing Code Enforcement Program. As with the other cities in the region
implementing irrigation ordinances, enforcement will most likely be initiated by citizen
complaints and Utility personnel that observe violations while working out in the field. Staff
proposes to enforce the program in the following manner:
st
1 Offense Door hanger delivered by Utility staff member
nd
2 Offense Warning issued by a Code Enforcement Officer
rd
3 Offense Citation issued by Code Enforcement Officer with a fine of $250
th
4 Offense Termination of water service by Water Utility Department
The offenses would accumulate on a per year basis, such that at the beginning of each year every
customer would begin with zero offences. Staff is also recommending that for the first year of
implementation, only warnings will be given.
Prior to implementation of the ordinance, staff will notify all local irrigators and irrigation
customers with high demands to inform them of the requirements being proposed in the
ordinance, and if necessary, meet with them individually to discuss concerns regarding
compliance with the ordinance. In addition, Water Utility staff will meet with Denton?s Facilities
and Parks and Recreation personnel to discuss issues related to citywide irrigation procedures
and ensure that the city?s facilities will be in compliance with the ordinance.

BACKGROUND
On March 28, 2005, staff presented the Public Utilities Board (PUB) (Exhibit 2) with the
strategy for updating Denton?s Water Conservation and Drought Contingency Plan. The update
th
is required by the Texas Commission on Environmental Quality. The March 28 agenda item
contained detailed information pertaining to the legislative history of, and recent legislative
th
changes to, the water conservation and drought contingency plan. The 78 Texas Legislature
passed seven water conservation bills in 2003. In short, two of the bills directly affected water
conservation plans, Senate Bill 1094 and House Bill 2660. SB 1094 created a task force on
water conservation to review, evaluate, and recommend levels of water use efficiency and
conservation for Texas. Requirements for quantified five-year and ten-year water savings goals
in water conservation plans were established by HB 2660. However, these goals are not
enforceable. A third bill passed in 2003, HB 2663, established the requirement for drought
contingency plans to include specific quantified goals for water use reductions during periods of
water shortages and drought.
th
The March 28 agenda item also contained information related to local and regional per-capita
water demand as well as the proposed strategy for complying with legislative requirements and
meeting water conservation goals. Denton?s water demand per-capita compares favorably with
the regional average, the City of Dallas?, and those of Dallas? larger customer cities. A number
of factors contribute to an area?s per-capita including variations in climate, municipal
demographics, water utility profiles, and local water conservation efforts. The City of Denton
implemented a water conservation plan in December of 1999. Denton?s current plan includes a
water conservation rate structure, a public education program, an informative web site, a
xeriscape program, residential water audits, and an effluent reuse program. To further reduce
EXHIBIT 2
potential water loss, the Water Department manages a waterline replacement program and
conducts annual water audits. The current plan also established a water conservation goal of a
fifteen percent reduction in per-capita water consumption by the year 2050.
Water Conservation Plan Executive Summary
The State Water Conservation Implementation Task Force (Task Force), with members
appointed by the Texas Water Development Board (TWDB), was created to fulfill the mandate
of the legislation incorporated in Section 6 of Senate Bill 1094. One of the mandates of SB 1094
was the establishment of state wide per-capita targets and goals to be considered by water
providers. For municipal water providers, the Task Force suggested a minimum annual
reduction of one percent in total per-capita, based upon a five-year rolling average, until such
time as the entity achieves a total per-capita of 140 or less. Based on historical per-capita data,
best management practices (BMPs) water savings analysis, and recommendations by the Region
C Water Supply Planning Group?s water conservation consultant, staff believes that a one
percent per year reduction in per-capita water use is obtainable over the next five and ten-year
periods. Denton?s specific goals are as follows:
Achieve 2009per-capita water use of 180 gpcd or less (five-year target). This represents a
reduction of 9 gpcd from the TWDB?s projected per-capita water use.
Achieve 2014per-capita water use of 171 gpcd or less (ten-year target). This represents a
reduction of 18 gpcd from the TWDB?s projected per-capita water use.
According to water savings analysis conducted by the Region C Water Supply Planning Group
and Denton Water Utilities staff, the water conservation goals of this plan can be accomplished
through continued implementation of Denton?s current conservation effort, water savings
resulting from low-flow plumbing fixtures and the new federal clothes washer standards, the
implementation of a lawn and landscape irrigation program, and the moderate growth of
Denton?s effluent reuse program.
The lawn and landscape irrigation program, a new update to the current plan, will be developed
and implemented in phases over the next few years. The program will include an ordinance that
may contain the following components: restrict watering to certain times of the day, deter
excessive watering of impervious surfaces, not allow watering during any form of precipitation,
require rain sensors on all new systems, and require proper maintenance of irrigation systems.
The implementation of the program in phases will allow time for staff to develop an ordinance
ensuring sufficient pubic participation as well as provide an adequate amount of time necessary
to educate customers about the requirements and restrictions of the ordinance.
Drought Contingency Plan Executive Summary
Revisions in Denton?s drought contingency plan are reflective of the 2005 changes to Dallas?
drought contingency plan. The need to coordinate Denton?s plan with the Dallas? plan is
appropriate due to the following reasons: 1) Denton?s water supply reservoirs (Lake Ray Roberts
and Lake Lewisville) are shared with Dallas and Denton is the minority water rights holder in
both reservoirs; 2) Denton is an untreated water supply customer of Dallas and will be affected
by restrictions that may be initiated by Dallas? plan, and 3) consistency between plans will
provide for a more effective implementation of Denton?s drought contingency plan as a result of
Dallas? regional media coverage. Revisions in Denton?s 2005 update to the drought contingency
plan include:
Minor changes to trigger conditions for the Type B water management condition;
Minor additions and edits to the menu of possible actions of water use restrictions for
demand reduction; and,
Adjustments to the specific quantified targets for water use reductions during periods of
water shortages and drought.
Revisions to the drought contingency plan were not previously presented to the PUB or the
Council Environment Committee as staff received Dallas? draft 2005 update subsequent to those
meetings.
Denton?s Water Conservation and Drought Contingency Plan has been updated to reflect the
changes describe above. The style of the plan has also been reformatted to closely resemble the
model plan developed by the Region C Water Supply Planning Group. The Denton Water
Conservation and Drought Contingency Plan is included in Exhibit 3.
OPTIONS
1. Accept the proposed Plan without modification.
2. Accept the proposed Plan with modifications.
3. Do not accept the proposed Plan.
RECOMMENDATION
Staff recommends Option 1, accepting the proposed ordinance without modification.

SUBJECT
Receive a report from staff, hold a discussion and provide direction concerning Denton's 2005
update to the Water Conservation and Drought Contingency Plan
BACKGROUND
Legislative History
The City of Denton adopted its Water Conservation and Drought Contingency Plan on December
th
7 1999. The plan was developed according to criteria established by the then Texas Natural
Resources Conservation Commission (now Texas Commission on Environmental Quality
(TCEQ)) and established a water conservation goal of a fifteen percent reduction in per-capita
water consumption by the year 2050. Per-capita, defined by the Texas Water Development
Board (TWDB), is the total amount of water diverted and/or pumped for potable water use
divided by the total population. Per-capita is also commonly referred to as gallons per capita per
th
day or gpcd. Since adoption of Denton?s plan, the 78 Texas Legislature passed seven water
conservation bills. The most notable of the conservation bills, all of which were passed in 2003,
are Senate Bill 1094 and House Bill 2660. SB 1094 created a task force on water conservation to
review, evaluate, and recommend levels of water use efficiency and conservation for Texas.
Requirements for quantified 5-year and 10-year water savings targets in water conservation plans
were established by HB 2660.
The State Water Conservation Implementation Task Force (Task Force), with members
appointed by the TWDB, was created to fulfill the mandate of the legislation incorporated in
Section 6 of Senate Bill 1094. The Task Force was assigned several tasks including identifying,
evaluating, and selecting Best Management Practices (BMPs) for municipal, industrial, and
agricultural water uses and evaluating the cost and benefits of the selected BMPs. As a result,
the Task Force developed TWDB Report 362, Water Conservation Best Management Practices
Guide.This guide, released in November 2004, includes 21 BMPs for municipal water users and
serves as a resource for entities volunteering to implement BMPs appropriate for their situation.
th
In addition to Report 362, the Task Force also produced a Special Report to the 79 Legislature.
This report, also issued in November 2004, recommended a standardized methodology for
calculating, reporting, and monitoring per-capita water use data. The Special Report also
established state wide per-capita targets and goals to be considered by water providers. HB 2660
required the commission and board to establish these goals. For municipal water providers, the
report suggested a minimum annual reduction of one percent in total per-capita, based upon a
five-year rolling average, until such time as the entity achieves a total per-capita of 140 or less.
EXHIBIT 3
March 27, 2006 PUB Item 4, Exhibit 3
Page 2 of 6
It is important to note that these goals are only guidelines and are not enforceable. HB 2660 also
required the commission and board to develop model conservation plans for water supplies; and,
beginning May 1, 2005, all water conservation plans must include specific, quantified 5-year and
10-year targets for water savings.
Legislative changes to Water Conservation and Drought Contingency Plans
Effective October 7, 2004, Title 30 Chapter 288 of the Texas Administrative Code (TAC)
entitled Water Conservation Plans, Drought Contingency Plans, Guidelines and Requirements
requires the holder of an appropriation of surface water in the amount of 1,000 acre-feet a year or
more for industrial, municipal and other non-irrigation uses develop, submit and implement a
water conservation plan meeting the requirements of Subchapter A of Chapter 288. The water
conservation plans must be submitted to the executive director of the Texas Commission on
Environmental Quality no later than May 1, 2005. In addition, retail public water suppliers
providing water service to 3,300 or more connections must also submit a drought contingency
plan to the executive director by the same date.
Changes to Title 30 Chapter 288 Subchapter A Rule 288.2 (Water Conservation Plans) and Rule
288.5 (Drought Contingency Plans) of the Texas Administrative Code (TAC), effective
November 7, 2004, include the following:
WATER CONSERVATION PLANS
Goals:
?
Until May 1, 2005, water suppliers were required to specify conservation goals for municipal
o
per-capita water use, the basis for development of such goals, and a time frame for achieving
the specified goals.
Beginning May 1, 2005, specific quantified five-year and ten-year targets for per-capita
o
water savings for municipal use are also required. The goals established by a public water
supplier are not enforceable under the code.
?Update of Plan:
Beginning May 1, 2005, public water suppliers must review and update its water conservation
plan, as appropriate, based on an assessment of previous 5-year and 10-year targets and any
other new or updated information. Update of the plan every five years requires reporting water
sales by specific user class (i.e., residential, commercial, institutional, industrial). Staff is
currently working on a process to code the specific customer user classes into the Harris billing
system.
DROUGHT CONTINGENCY PLANS
?Quantified Targets for Water Use Reductions:The Drought Contingency Plan must include,
specific quantified targets for water use reductions to be achieved during periods of water
shortage and drought.
Region C, City of Dallas (including customer cities), and City of Denton per-capita
Population and water demand numbers are available at the TWDB website. Based on TWDB
water demand and population numbers for the year 2000, the average per-capita for Region C
was 246. The City of Dallas? per-capita for the same year was higher at 262. Per-capita for
March 27, 2006 PUB Item 4, Exhibit 3
Page 3 of 6
Denton in 2000 was 189, less than both Dallas and the Region C average. Exhibit 1 shows the
year 2000 per-capita for the City of Dallas, the City of Denton, and all other Dallas customer
cities with a population greater than 25,000. Compared to Dallas and their larger customer cities,
Denton?s per-capita water demand (189) is less than the mean (199) and just slightly under the
median (190). It is important to note that the year 2000 is being used to establish baseline per-
capita for the following reasons:
1) the population figures are more accurate than any single-year population estimate between
1990 and 2000;
2) according to the Palmer Drought Severity Index the year 2000 was the driest year in the last
decade for the majority of regions in the State; and,
3) the year 2000 water use data also takes into account the water use savings that have resulted
from the 1991 State Water-Efficient Plumbing Act and conservation programs implemented
by the water utility.
Update to Denton?s Plan
The current plan meets all TCEQ requirements for Water Conservation and Drought
Contingency Plans except for the recently added specific 5-year and 10-year conservation goals
and the submittal of those goals in the updated plan to the TCEQ by May 1, 2005. Denton?s
current Drought Contingency Plan already contains quantified targets for water use reductions
during times of shortage or drought. Staff will review those targets prior to preparing the final
draft of the updated plan.
Due to having one of the highest per-capita demands in Region C, and in the state, the City of
Dallas is currently pursuing an aggressive water conservation effort. Denton?s per-capita, on the
other hand, is substantially less than Dallas? and compares favorably to Region C as a whole. In
determining the need for conservation, it is also important to consider supply and demand;
Denton?s short-term treatment and supply capacities exceed demand. Due to these factors, staff
suggests pursuing a less aggressive conservation effort than Dallas. Staff also believes it is in the
best interest of DWU to take a more moderate approach to water conservation at this point in
time due to uncertainties pertaining to potential regulatory consequences of specific water
savings goals in the future. Nonetheless, Denton will benefit from Dallas? effort through their
regional media campaign. In staff?s opinion, Denton already has a respectable water
conservation plan, which consists of the following components:
Conservation Water Rate Structure for Residential Rate Class- comprised of an inverted-
block rate such that the price of water increases with increasing consumption
Public Awareness and Education Program - includes bill inserts, brochures, a school
education program, public speaking engagements, and public service announcements.
Web Site - DWU maintains a web site with water conservation tips and answers to frequently
asked water conservation questions.
Xerioscape Program - offers a free semi-annual landscape management class and distributes
Texas Smartscape CDs at local events and upon request
Waterline Replacement Program ? replaces waterline on a worst-first basis which is effective
in reducing the number waterline breaks
March 27, 2006 PUB Item 4, Exhibit 3
Page 4 of 6
Annual Internal Water Audit ? water accounting system useful for estimating and controlling
unaccounted-for water
Residential Water Audits ? trained staff conduct on-site water audits for residential customers
identifying potential water waste and demonstrating water conservation techniques.
Effluent Reuse Program ? reclaimed wastewater is sold to customers for non-potable uses,
primarily irrigation.
Staff feels the TWDB Task Force?s suggested annual reduction of one percent per year in total
per-capita may be reasonable for Denton. Based on available data, staff believes the goal can be
achieved through continued implementation of the components in the current plan,
implementation of a lawn and landscape irrigation program, and moderate growth of Denton?s
reclaimed effluent reuse program. The lawn and landscape irrigation program would be
developed and implemented in phases over the next few years. The program would include an
ordinance that would restrict watering to certain times of the day and would deter excessive
watering of impervious surfaces. The ordinance would not allow watering during any form of
precipitation and would require rain sensors on all new systems. Proper maintenance of irrigation
systems necessary to reduce waste of water would also be required. The implementation of the
program in phases would allow time for staff to develop an ordinance ensuring sufficient pubic
participation as well as provide an adequate amount of time necessary to educate customers
about the requirements and restrictions of the ordinance.
The Consultant for the Region C Planning Group responsible for Region C Water Conservation
believes that Denton will likely do its share in meeting the long-term Regional conservation
goals based on automatic water savings and the implementation of moderate conservation
measures. Automatic water savings result from the 1991 state requirements for low-flow
plumbing fixtures, the impact of increasing water rates over time, and a new federal clothes
washer standard that will go into effect in 2007. Moderate conservation measures include public
and school education programs and a Water Waste Prohibition ordinance (different terminology
for lawn and landscape irrigation ordinance). The Consultant estimates that these components
will reduce demand by 6.7 percent in 2010. At this time, the total projected savings in the
Consultant?s estimates do not include the savings that will result from Denton?s reuse program.
The Consultant is currently working with staff to estimate savings from reuse.
Twenty-one Municipal BMPs were published in the Task Force?s Water Conservation Best
Management Practices Guide. Exhibit 2 shows which BMPs are already being implemented,
which BMPs will be implemented in the first five years of Denton?s updated Water Conservation
Plan, and whether or not the BMP is being recommended for Denton by the Region C
Consultant. In order to meet the five and ten-year conservation goals Denton will continue to
implement the current the plan, phase in a Lawn and Landscape Irrigation Ordinance, and March
27, 2006 continue to expand the reuse program. In addition to the proposed conservation plan, a
large portion of per-capita water savings will result from low-flow fixtures, increasing rates, and
the federal clothes washer standards.
Denton?s specific goal of a one percent reduction of per-capita per year in the first five years,
based on estimated savings from current conservation measures, a lawn and landscape irrigation
ordinance, and moderate growth in Denton?s reuse program over the time period, would result in
a 9-gallon per day reduction in per-capita by the year 2009. Current conservation measures
PUB Item 4, Exhibit 3
Page 5 of 6
include savings from state required low-flow plumbing fixtures, the implementation of the
federal clothes washer standards, increasing water prices over time, and the water conservation
components of Denton?s current plan. By the year 2014, the second required evaluation and
update period of the plan, meeting the one percent reduction in per-capita per year would result
in a per-capita reduction of approximately 18 gallons per day.
OPTIONS
1) Establish specific 5-year and 10-year water savings goals at reducing per-capita by
one percent per year
2) Establish specific 5-year and 10-year water savings goals that are more aggressive
than reducing per-capita by one percent per year
3) Establish specific 5-year and 10-year water savings goals that are less aggressive than
reducing per-capita by one percent per year
RECOMMENDATION
Staff recommends Option 1; establish specific 5-year and 10-year water savings goals at
reducing per-capita demand by one percent per year. The established goal could be achieved
through automatic water savings, continued implementation of Denton?s Water Conservation
Plan, a phased in implementation of a Lawn and Landscape Irrigation Ordinance, and the
moderate growth of Denton?s reclaimed effluent reuse program.

FROM: Tim Fisher, Assistant Director Water Utilities
THRU: Jim Coulter, Director of Water Utilities
DATE: January 13, 2006
SUBJECT: Water Conservation & Drought Contingency Plan Update on Water Supply
Condition
Denton Water Utilities staff continues to monitor water levels in Lake Lewisville and Lake Ray
Roberts and water system demands in accordance with the Denton Water Conservation &
Drought Contingency Plan. The Drought Contingency Plan identifies three different types of
water shortage situations which might occur and that would result in different types of demand
side management strategies. These water shortage conditions are listed below:
Type A ? Water supplies are low.
Type B ? Water demand approaches system capacity.
Type C ? Short-term deficiencies limit supply capability.
The plan also identifies four stages of management strategies designed to address the severity of
the water supply shortage situation. These include:
Stage 1 ? Mild
Stage 2 ? Moderate
Stage 3 ? Severe
Stage 4 ? Emergency.
EXHIBIT 4
Memo to Mayor and Members of the City Council
January 13, 2006
Page 2 of 4
The Plan was originally adopted by the City Council on January 4, 2000, and was revised in
accordance with TCEQ requirements by staff and adopted by the City Council on April 19, 2005.
Since this plan has been adopted, the Cities of Denton and Dallas initiated Type A, Stage 1 or 2
management strategies during much of the summer of 2000. Due to high summertime water
demands coupled with a mechanical failure of one of the city?s lake station pumps, Denton
activated Type B, Stage 1 and Type C, Stage 2 management strategies during the late summer of
2001.
The current lake level conditions for Lake Lewisville and Lake Ray Roberts have declined since
the spring of last year and the severe drought weather conditions in the DFW area over the past
twelve months has resulted in a steady decline in conservation pool levels over the past nine
months. As a consequence, staff anticipates activation of a Type A trigger condition is a real
possibility within the next three to four months. Depending upon how the weather patterns occur
over the next five months, it is possible that we could see Type A trigger conditions to progress
from Stage 1 to Stage 2 or even Stage 3 conditions by mid to late summer.
I have enclosed a summery of Type A plan triggers along with some information showing recent
trends in the water supply volumes (expressed as % of conservation pool) for the Dallas five-lake
system (Lakes Ray Roberts, Lewisville, Grapevine, Hubbard and Tawakoni) as well as the
Denton/Dallas two lake supply system (Lake Lewisville and Lake Ray Roberts). While Lake
Lewisville has dropped below 64% of conservation pool levels, Lake Ray Roberts has nearly
88% of its conservation pool water supply.
The Denton/Dallas water supply system is in better condition than many of the other regional
water suppliers. Some of these suppliers have had to implement water restrictions due to
reaching their drought plan trigger conditions earlier in this drought period than the cities of
Denton and the Dallas Water Utilities system and their wholesale customers. Denton activates
their drought plan at the same time Dallas Water Utilities does under Type A trigger conditions
due to the multi lake system operated by Dallas and the shared lake system with Denton.
I have also enclosed information on monthly rainfall amounts for last calendar year recorded at
the City?s rain gauge station at the Lake Lewisville Water Treatment Plant compared to the
average monthly rainfall over the past 17 years from our Utilities Forecast. The total rainfall for
calendar year 2005 was 16.". The average rainfall for the prior 17 years was 37.86" per year.
13
The lowest rainfall during that time frame was 24.19" in 1996. The second lowest amount was
27.67" in 1999. That forecast also averages the summer rainfall (June - August) for those 17
years. The summer average is 8.7" versus 1.57" for 2005. On the forecast graph a dry year is
noted as 27", a normal year is 37" and a wet year is 47". Needless to say, 2005 was a very dry
year and we were very fortunate to have a very wet year in 2004 that help keep lake levels near
conservation pool levels through much of the spring of 2005.
Please be advised that Stage 1 drought plan activation result in mandatory water
will not
restrictions for any retail or wholesale water customer but will begin the launching of the City?s
drought plan public education program. Stage 2 drought plan activation introduces mandatory
water restrictions for the City of Denton governmental customers, including all City irrigated
Memo to Mayor and Members of the City Council
January 13, 2006
Page 3 of 4
landscaping and parks. Stage 3 drought plan activation introduces mandatory water restrictions
for all retail and wholesale water customers.
The water utilities staff has been working with the public information staff to prepare for
implementation of the drought plan since it was revised last year. The city?s web page has the
updated version of the city?s adopted Water Conservation and Drought Management Plan
available for the public to download and view in PDF format. There are also links for water
saving tips, information on the city?s water audit program and water conservation program as
well as information on the new twice a week watering schedule that replaced the more
complicated five day watering schedule that was a part of the 2000 version of the drought plan.
All of these can be accessed through the Water Utilities section of the city?s website or through
the site search window.
Recent long-range weather forecasts suggest the next six months will continue to be drier than
normal for the North Texas region. Based upon these conditions, it may be advisable for the
City to consider promoting an accelerated water conservation public education program in
advance of formal activation of the drought management plan. In addition, the 2005 updated
version of the water conservation plan anticipated implementation of a Water Waste Ordinance
by the third year of the five year plan (the summer of 2007). It may be prudent to consider
implementing this ordinance for implementation by this up coming summer. The Water Waste
Ordinance would include provisions similar to those adopted by the Cities of Dallas in 2001 and
Arlington in 2005. Key provisions of a Water Waste Ordinance include restrictions on:
Water irrigation during the heat of the day during summer months.
Excessive watering resulting in running water entering streets and storm drains.
Watering of driveways, pavements or sidewalks.
The Water Waste Ordinance would also require installation of rain/freeze sensors for all new
sprinkler systems. Public acceptance of this type of water conservation ordinance will likely be
better during a drought condition than when lakes are full and when rainfall is plentiful. If the
City Council agrees with this suggestion, staff can begin working on a draft ordinance for the
Public Utilities Board review and for a City Council work session within the next few months.
With respect to other plan trigger conditions, forecasted water demands over the peak summer
demand period this summer should not result in activation of the plan due to Type B trigger
conditions. With the completion of the new Lake Ray Roberts Water Treatment Plant in 2003,
Type B triggers should not be of concern for the City of Denton for the next five to eight years.
Please be advised that as water system demands increase over the summer months, there is
always an increased risk of having a Type C emergency event. A Type C trigger condition
occurs when an unplanned emergency event reduces existing water system capacity to a level
approaching current water system demand. Examples of these include a major water main break,
an extended power failure to a major treatment plant or pump station facility, or the mechanical
failure of a large pump. While Type A and Type B trigger conditions impact all of the water
Memo to Mayor and Members of the City Council
January 13, 2006
Page 4 of 4
customers, Type C trigger conditions may only impact portions of the distribution system in
some cases (for instance a pump station failure for a specific pressure zone).
Staff will keep you apprised of the water supply system and brief you if activation of the drought
plan due to Type A trigger conditions becomes necessary. If activation of the drought
management plan is advisable, staff will notify you and discuss the recommended course of
action. If you have any questions, please contact me at 940-349-7190 or via e-mail at

20Fisher presented this item, stating that implementation was originally scheduled for 2007, but
21due to drought conditions during the year, staff was accelerating the schedule and would like
22implementation to be this summer. Key issues of the ordinance would be a summertime ban on
23water irrigation during the heat of the day, or during times of precipitation; excessive watering
24resulting in running water entering streets and storm drains, watering of driveways, pavements or
25sidewalks; and, proper maintenance of sprinkler systems.

27There was a general discussion regarding proposed enforcement strategies. Board Member
28Smith stated that the conservation goals and requirements identified in the Denton Development

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.
