A. Carl Gene Young Sr. Park Sprayground Opening – The City of Denton Parks and
Recreation Department and volunteers are excited to announce the sprayground is
ready for play and invites residents to join in a family-friendly celebration on
Saturday, May 12 from noon to 1 p.m. at Carl Gene Young Sr. Park. Attached is
a press release with more details. Staff contact: Maria Dension
B. Disaster Drill – The 2018 full-scale mock disaster drill took place on Friday, May
4. First responders were tasked with responded to a simulated hazmat and mass
casualty incident near the Downtown Denton Transit Center. This drill was
designed to test the response capabilities of first responders, hospitals, and other
agencies. The City would like to thank our partners who helped make this drill
possible: DCTA, First Transit, Union Pacific Railroad, Transportation Community
Awareness and Emergency Response (TRANSCAER®), Denton Fire department,
Denton Police department, Atrium Medical Center, Texas Health Presbyterian
Denton, Medical City Denton, the Heart Hospital Baylor Denton, North Central
Texas Council of Governments (NCTCOG), UNT, TWU, and mutual aid partners.
Staff contact: Michael Penaluna
C. Main Page of Website – The Communications team has launched a new section of
the City’s homepage: Quick Links. This component allows the City to feature
additional information on the homepage, or link to relevant or frequently visited
pages. The City can feature up to eight items through this function. In addition, the
social media widget of the City’s homepage is not currently active. Some social
media platforms, such as Facebook, have recently changed their terms of service
which requires some changes be made on the development side of the City’s
website. Our website developer is currently working through these issues with
social media platforms and the widget will be added back to the homepage as soon
as possible. Staff contact: Jessica Rogers
D. Election Day – Saturday, May 5 is Election Day. Unlike early voting, eligible
voters casting a ballot on Election Day must vote at their pre-determined precinct
voting location. A list of the polling locations by precinct is attached. For more
information about the election (including polling locations), residents can either
go to the County’s elections page (www.votedenton.com) or go to the City’s
“Vote” page by going to the City’s homepage (www.cityofdenton.com) and
searching “vote” in the upper right hand corner. This week, staff also added a
Quick Link to elections information on the homepage. Staff contact: Jennifer
Walters.
E. Traffic Safety Fund/General Fund Overtime Charges – In Summer 2016, Denton
PD began using an automated timekeeping system. This system is an electronic
system that automates many of the timekeeping functions, including assigning
time worked as either “overtime” or “straight time.” Based on the City’s policy,
only hours recorded in excess of an employee’s assigned hours (e.g. in excess of
40 hours per week) are recorded as overtime. Additionally, Denton PD were
operating with the direction to charge hours worked reviewing red light camera
citations as overtime, so not to interfere with the officers’ primary patrol
duties/responsibilities, regardless of when those hours fell in a pay period.
Last week, staff became aware that the timekeeping system’s automation had
created instances where overtime that should have been charged to the Traffic
Safety Fund was charged as straight time. Conversely, time that should have been
recorded as straight time in the General Fund was recorded as overtime. Officers
were coding hours worked to the correct fund and the proper amounts were paid
to officers, but the payroll system was not recognizing Traffic Safety Fund
overtime hours as “overtime” unless the employee had already exceeded their 40
hours. Instead, it would record hours worked later in the pay period (regular
General Fund hours) as overtime.
The Denton Police Department and Finance staff are in the process of reviewing
payroll and overtime records to ensure that the straight time and overtime rates are
applied to the proper fund and will make an adjusting entry to correct any instances
where the system charged the wrong fund. Staff anticipates this being complete by
mid-May and will provide that information when it is available. Staff contact:
Antonio Puente/Lee Howell
F. DCTA Denton Update – Please see attached a monthly update report from DCTA
with information on the special event service for the Arts & Jazz festival,
information on the vanpool program, passenger amenities, and announcement that
the non-profit pass discount will be increased from 25% to 50% as of June 1, 2018.
Staff contact: Mark Nelson
G. ADA Transition Plan – To comply with federal law, cities are required to develop
an American with Disabilities Act (ADA) Transition Plan. An ADA Transition
Plan provides a schedule and plan for the removal of communication, physical
barriers, and architectural barriers. Developing an ADA Transition Plan is a very
involved process. In developing the plan, citizen input is necessary to understand
the barriers that people with disabilities encounter in their everyday lives in their
interaction with the city. Second, completing an assessment on the condition of
city infrastructure (i.e. sidewalks and ramps) and areas where these components
of infrastructure are missing and needed to allow those with disabilities to traverse.
The City of Denton has recently begun the early stages of implementing the ADA
Transition Plan process by assigning the project to the Bike/Pedestrian Office,
which is located in the Capital Projects Department. The Bike/Ped Office has
engaged the services of the engineering firm Kimley Horn to develop ADA related
documents and draft an ADA Transition Plan template. This template includes
primary components of the ADA Transition such as “Notice to Citizens”
document, a grievance procedure, a grievance form, and a sidewalk evaluation
checklist. The work on the template forms has been completed and will be posting
these documents on the City’s website within the next two weeks. Once these items
are posted, staff will inform City Council as to their location on the City’s website.
The second phase of the ADA Transition Plan is to develop a Request for
Proposals (RFP) to conduct an inventory of city sidewalks and ramps. The
Bike/Ped Office is currently working with Purchasing to advertise the RFP at the
end of May 2018 for the data collection study which will be conducted by an
outside vendor. Once a vendor is selected this summer, the data collection effort
will begin and should be completed by the end of summer. After the sidewalk data
is collected, City staff will be able to more pro-actively create a work plan for
bringing non-compliant sidewalks into compliance instead of the current repair
method which is managed on a reactive (complaint) basis. Staff contact: Pritam
Deshmukh
H. Sherman Drive – A recent issue was raised regarding a person who witnessed an
individual in a wheelchair riding in a lane of traffic along Sherman Drive between
Locust and Bell. Recently, city staff drove this segment of Sherman Drive looking
for missing sidewalks. Based on staff’s observation there is a continuous sidewalk
along the north side of Sherman Drive within this segment. There are no gaps in
sidewalk on the north side but there are locations where the sidewalk crosses
residential driveways which may not be ADA compliant. There is no sidewalk that
exists on the south side along Sherman Drive between Locust and Bell.
Based on the original concern it is not clear if the individual in the wheelchair was
on the north or south side of Sherman Drive when they decided to use the travel
lanes. Given the concern and a review of existing conditions, staff is seeking
additional clarification from the resident that forwarded the concern. Once this
information is received, staff recommends meeting with the wheelchair bound
resident to better understand the circumstances for using the street rather than
using the existing sidewalk. This will help identify and isolate the problem so that
a plan can be developed to resolve the issue. Staff contact: Pritam Deshmukh
I. Citizen Service Request Application – The City has
contracted with CitySourced to develop a citizen
request application and a soft launch of the
application is targeted for the end of June. The
application is currently in development and an
internal staff training is scheduled for this month. A
mockup of the home screen for the mobile
application is shown to the right.
Staff is planning to have a soft launch with a limited
number of request types to ensure that citizens have
a positive user experience and are more likely to
continue to use the application. Features of the
application will include the ability to submit requests
and add useful information including links to utility
bill pay, Parks program registration, and social
media, and FAQs.
In addition to the mobile app features, there are system wide features that will
benefits to both citizens and staff including:
Tracking of requests and escalations to supervisors if preset deadlines have
been exceeded.
Automated routing of request directly to the departments to reduce delay in
request routing.
Automatic status updates to citizens to keep them informed of progress on their
request.
Reporting capabilities to provide data on request types, counts, response times,
and more.
Increased transparency through a map display of all requests, except requests
reported anonymously by citizens.
CitySourced was recommended by staff and presented to the Committee on
Citizen Engagement in February. CitySourced is used by a number of cities locally
including Bedford, Frisco, Prosper, and Weatherford. Staff contact: Sarah
Kuechler
J. Libraries ROCK – Many thanks to Denton’s Eric Pulido, from the folk rock band
Midlake, for playing the part of a head-banger rocker (red wig) in a new video
produced by DTV. The spot, “Libraries ROCK”, was written by librarian Kerol
Harrod and raises awareness for the Denton Public Library’s summer reading
challenge. https://youtu.be/oCTyfTQqOfA
The Denton Public Library is challenging each person in the community to read a
total of 10 hours this summer. The Summer Reading Challenge starts on May 24
at all three Denton Public Library locations and online. This year you can sign up
and complete the program online or complete the challenge on paper by picking
up reading logs at the Library. Staff contact: Billy Matthews
K. Municipal Code Corporation – At the May 1 Council meeting, Council Member
Ryan requested information on updates to the Code of Ordinances through
Municipal Code Corporation (Municode). Ordinances amending the Code of
Ordinances or the Development Code are sent to Municode to be codified as
supplements. The on-line version of the Code of Ordinances is updated quarterly
with the Development Code updated semiannually. Paper supplements are printed
on an annual basis and distributed to multiple department across the organization.
Cost for this service is approximately $5,000-$7,000 for hundreds of updates and
appears that this is an economic option to perform this public service.
Regarding the update of the Charter amendments, staff inadvertently missed
sending the information to Municode. Municode is currently proofing those
changes and will have the information posted on-line within two weeks.
Staff will contact Municipal Code Corporation for other available options for more
frequent updates and the associated costs. Staff contact: Jennifer Walters
L. 2018 Mosquito Season – The 2018 Mosquito season officially started on May 1
with the City of Denton entering Risk Level 2 – Enhanced Response of the
Mosquito Surveillance and Response Plan. Typically, Risk Level 2 is triggered
before the mosquito season is underway and centers on activities citizens can do
to help the City control the mosquito population. At this Risk Level, the probability
of human outbreak of the West Nile virus is low. Strategies for protecting human
health and methods for minimizing mosquito populations are the main control
measures emphasized under Risk Level 2.
The City’s 2018 Mosquito Surveillance and Response Plan (“MSRP”) is a
comprehensive plan aimed at reducing the risk of illness due to West Nile virus.
A copy of the plan in attached and accompanied by a communications plan for
public education and notification. Each of the five risk levels and corresponding
public education and notification activities are outlined in this plan.
Mosquito monitoring started this week, and will continue on an approximately
weekly basis until the end of the season in late fall. Monitoring provides
information on mosquito populations and the presence of mosquito-borne viruses.
Staff uses this information to establish risk levels in accordance with the protocols
in the City of Denton’s Mosquito Surveillance and Response Plan, and each Risk
level triggers a specific public communication and mosquito control efforts.
Although the program is designed to assess and mitigate the risk from West Nile
Virus, staff continues to devote efforts to assessing risks from emerging mosquito
borne diseases such as dengue fever, chikungunya virus, and Zika virus.
A press release was distributed on May 3 to inform the public of mosquito season
beginning and education on how to prevent mosquito breeding grounds. It also
announced that the Utilities Department has a limited supply of Bti briquettes that
residents can pickup in limited quantities (two per resident) while the supply lasts.
More information and updates will be posted and available on the City’s website.
Staff contact: Deborah Viera
M. TxDOT Notice of Public Meeting – TxDOT has provided notification of a public
meeting for the purpose of soliciting public comments on the proposed project to
widen a 3.6 mile stretch of FM 1173, from FM 156 to I-35. The project would
include the expansion of the current 2-lane, rural roadway to a 6-lane, urban
roadway. The public meeting will be held on Tuesday, May 8, 6 to 8 p.m. at the
Krum High School Cafeteria (700 Bobcat Blvd.). A copy of the notice is attached.
Staff contact: Mark Nelson
III. Community Events
A. Mayor’s Day of Concern for the Hungry – Mayor Chris Watts announced the
Mayor’s Day of Concern for the Hungry food drive at tonight’s City Council
meeting. This is the seventh year of the event encouraging residents and businesses
in Denton to help address hunger in the community with a one-week food
collection drive from May 7-11. Every resident and business in Denton can help
address hunger by dropping food donations from May 7-11 at participating
business and non-profit locations throughout the city. This is also the first year that
monetary donations will be accepted online. Food pantries are able to make each
dollar go further by purchasing in bulk through existing partnerships. Every $1
donated buys 3 pounds of food. More information is found here:
www.UnitedWayDenton.org/MDOC. Staff contact: Sarah Kuechler
B. Cycle with the City – The first Cycle with the City event of 2018 will be on
Wednesday, May 9, from 6 to 7:30 p.m. in connection with the celebration of May
as “Bike Month.” Anyone wishing to participate should meet at North Lakes Park
(2001 W. Windsor Dr.) in the parking lot next to the playground (see attached).
This year, the ride will feature the expanded Evers Trail and will be led by
outgoing City Council Member Dalton Gregory to thank him for his continued
support of bike projects in Denton. Don’t forget to bring your bike to participate
in this fun event. For more information about bicycle safety and the City’s Bike
Plan, go to www.bikewalkdenton.com. Staff contact: Katherine Welch

Carl Gene Young Sr. Park Sprayground Grand Opening
DENTON, TX, May 3, 2018 – Come celebrate the grand opening of Denton’s new all-inclusive
sprayground! The City of Denton Parks and Recreation Department and volunteers are excited to
announce it’s ready for play and residents are invited to join this family-friendly celebration on
Saturday, May 12 from noon to 1 p.m. at Carl Gene Young Sr. Park.
The grand opening will begin at noon with a welcome address and brief remarks from City
officials, followed by a ribbon cutting ceremony. Families are welcome to pack a picnic and stay
all day or enjoy complimentary Chick-fil-A sandwiches while they last.
The new sprayground, designed by Kraftsman, is an all-inclusive aquatic play area thoughtfully
designed so children of all abilities can play together. The aquatic play area features a tall water-
flower with multi-level spray effects and translucent shadow casting petals. In addition, the core
play area offers flush mount ground sprays and essential sprayers that are designed to stimulate
the senses and influence multigenerational activity of all abilities to promote inclusive play.
The idea for a free community sprayground was inspired by a group of local parents led by
Amber Briggle and gained the support of City Council, the Denton Parks Foundation, and the
City of Denton Parks and Recreation Department. The community’s grassroots campaign raised
$10,493 that ultimately encouraged voters to approve the sale of $200,000 general obligation
bonds followed by the City’s commitment of $41,600 in Park Development Funds.
The new sprayground is the latest of this park’s upgrades that previously included a new swing
set and new benches. Construction will begin this summer on a new permanent restroom facility
so families can make a day of playground and sprayground fun.
“This truly has been a community effort from the start,” said resident and volunteer Amber
Briggle. “Thank you all and see you at the park May 12!”
Carl Gene Young Sr. Park is located at 327 S. Wood St. For more information about Denton’s
parks and playgrounds, visit www.dentonparks.com.

DCTA Update
May 3, 2018
DCTA has been provided a copy of Resolution 18-654 outlining a formal request by the City of Denton to
establish an annual passenger amenities program and specifying a $250,000 annual investment in the proposed
program.
DCTA reported good participation by the community in the special event service for the Arts and Jazz Fest
provided on April 27 -29. DCTA stated Bus service was well utilized and no issues were reported with pickup
or drop-off. No riders were left standing and no capacity issues with the Med-Park parking lot were
experienced. Patrons appeared to be well accepting of remote parking. The additional rail trip was reported as
not beneficial, no ridership. Saturday service (with complimentary fare) did show positive support. DCTA
summation: sustain bus service and the fare promotion. Do not add more rail trips. DCTA staff and City of
Denton staff will be scheduling a meeting with event organizers later this month to review lessons learned
and opportunities to improve the service in the future. Following data was provided by DCTA:
Shuttle Bus - Two buses provided 30 minute headways to/from Medpark
Friday, April 27, 3:00 PM to 12:30 AM 166 rides
Saturday, April 28, 11:00 AM to 12:30 AM 1,036 rides
Sunday, April 29, 11:00 AM to 11:30 PM 506 rides
TOTAL RIDES: 1,708
Rail Ridership - One additional trip added for Friday night, normal service Saturday, no service Sunday.
Friday, April 27, 2018 1536 (no passengers on added trip)
Friday, April 28, 2017 1903
Saturday, April 28, 2018 802
Saturday, April 29, 2017 482
Vanpools
Last month Mayor Pro Tem Bagheri requested data regarding the DCTA Vanpool program. Vanpool program
is financially supported through the North Central Texas Council of Governments (NCTCG) and is made
available to those commuting to or from a Denton County location (DCTA operating area). The program is
contracted through Enterprise: Vanpool participants pay 65% of cost of the van and all fuel, NCTCOG grant
funds the remaining 35% of the cost. Typical cost is $487/month for 8 passenger and $520/month for 12
passenger. Van is typically issued to one person who is responsible for the van. This person also coordinates
maintenance through Enterprise. DCTA currently has 31 vans in service now and two business have a total
of 28 vans issued to employees; Peterbilt – 26 vans and Labinal – two vans.
DCTA Denton Update – May 2, 2018
Arts & Jazz Festival
The Arts and Jazz Shuttle Service was a big success with an excess of 1,700 riders over the course
of the weekend. The buses were well utilized and met the ridership demands. The extra rail service
on Friday night did not generate additional riders. DCTA had a booth at the event and the combined
effort was a strong presence. DCTA was happy to support this important event, and will work with
City staff and event organizers to review results and plan for next year.
Non-Profit Pass Discount
DCTA currently offers a 25% discount for the sale of passes directly to non-profit organizations. The
intent to help support those members of our community that need the help accessing critical facilities
the most. We are pleased to increase this discount to 50% effective June 1, 2018.
Passenger Amenities
DCTA is working closely with City staff this year (Thanks to Mark Nelson and Pritam Deshmukh!) to
continue our efforts to improve the ridership experience on our buses. Planned improvements for a
shelter at the Heritage Oaks location and the bench at the Uptown Student Housing complex are
complete. Work continues on the concrete pads.

1.0 INTRODUCTION
Mosquitoes are insects that belong to the order Diptera, or True Flies. Female
mosquitoes have modified mouthparts that form a long piercing-sucking proboscis, while
male mosquitoes have mouthparts that are incapable of piercing skin. There are over
2,500 different species of mosquitoes that have been identified throughout the world,
with approximately 150 species occurring in the United States. The Texas Department of
Health estimates that there are approximately 82-84 mosquito species in the State of
Texas, although only about 12 of these mosquito species have been implicated in the
transmission of serious diseases.
Mosquitoes typically need still, stagnant water that is isolated from fish or other small
predators to complete their metamorphosis from egg to adult. Larval habitats can range
from marshes, freshwater wetlands, and tree holes to human-made structures like
catchments, drains, gutters, and discarded tires. Not all species feed on humans and
other mammals, and many species feed mostly on birds, amphibians, or reptiles. Only a
small percentage of the known mosquito species are considered to be diseases vectors.
Although only a small percentage of mosquito species are capable of transmitting
diseases, mosquitoes are still considered to be a very important vector for disease
transmission. Within the United States, the occurrences of mosquito-borne illnesses
have been relatively rare in recent years. However, epidemics of mosquito-borne
diseases were once common in the United States. Outbreaks of Yellow Fever have been
recorded as far north as Philadelphia during the Colonial Period, and Dengue fever was
prevalent along the Gulf Coast until the mid-1940s. At one time, malaria was well
established in the continental United States, especially in the south. Other mosquito-
borne illnesses like LaCrosse, St. Louis, and Eastern Equine Encephalitis are still threats
in certain areas of the country. Although many of these historical mosquito-borne
diseases have been eliminated or at least controlled, the introduction and subsequent
rapid spread of West Nile Virus within the United States is a topic of current concern.
Mosquitoes may be controlled through a variety of different physical, chemical, and
biological methods. Physical methods usually involve source reduction, which is simply
the physical removal of mosquito breeding habitats. Biological measures mainly center
on the use of bacteria that kill mosquito larvae or the use of natural mosquito predators.
Chemical treatment typically involves the application of pesticides to attempt to control
larva or adult mosquito populations.
Mosquito control pesticides are applied by various means, depending on the type and size
of the area being treated. No matter how pesticides are applied, however, pesticides
have the potential to impact non-target species, including humans. Depending on the
pesticides used, potential impacts may include acute or chronic toxicity, reproductive and
/ or developmental effects, and indirect effects through the food chain. The tests
required for pesticides registration also may not address non-target impacts.
Information regarding the effects of inert ingredients in pesticide formulations, food
chain effects, multi-generational effects, and the interaction of specific pesticides with
2
other chemicals in the environment may also be lacking. It is therefore important to
realize that there are risks associated with the use of pesticides just as there are risks
associated with the potential for human or animal infection by a mosquito-borne illness.
The purpose of this response plan is to provide a systematic way to consider and balance
the risks associated with mosquito control measures.
2.0 Objectives
The City of Denton Mosquito Surveillance and Response Plan was developed to meet
several objectives. Specifically, the Plan:
Provides guidelines and information on mosquito populations, prevalence of
diseases, and control strategies;
Provides a systematic approach for using mosquito sampling and human disease
data to establish Risk Levels;
Establishes actions that will be undertaken for each Risk Level;
Provides municipal staff and elected officials with a decision-support system;
Outlines the roles and responsibilities of municipal staff and elected officials.
3.0 West Nile Virus (WNV) Concerns
West Nile Virus was first recorded in North American during August 1999 shortly
following the Center for Disease Control and Prevention (CDC) and the New York City
Department of Health responses to an unusual outbreak of encephalitis in northern
Queens, New York. The cause of the observed illnesses was determined to be West Nile
virus. During 1999, approximately sixty people were diagnosed with West Nile virus
and seven elderly residents died from the infection. During the summer of 2000, WNV
activity was detected again in New York City and appeared to be spreading. Fourteen
people in the City of New York were diagnosed with acute WNV infection, six were
identified in New Jersey, and 1 was reported from Connecticut. Outside of New York,
WNV was detected in 12 states and in the District of Columbia. During 2001, the virus
appeared again in New York City, causing seven cases that required hospitalization. In
2001, a total of 66 human cases with nine fatalities were reported throughout the nation,
mostly spread throughout the eastern United States. During 2002, there were 4,156
laboratory-positive human cases and 284 deaths. The number of cases increased
dramatically in 2003 as the disease spread westward, with 9,862 cases and 264 deaths.
After 2003, annual national case counts have ranged from a low of 712 during 2011 to a
high of 5,674 in 2012. In 2012, the highest incident rates in the nation were observed in
the North Texas region, including Denton County. Fortunately, subsequent seasons have
been relatively mild when compared to 2012.
The relatively rapid spread of West Nile virus and the increase in disease incidence
indicates that WNV is permanently established in the United States. It is likely that the
virus survives the winter either within birds that remain in the area or within mosquitoes
that survive the winter. When spring returns, the virus can amplify within birds and is
readily passed to early season mosquitoes. As mosquito populations increase,
3
mosquitoes begin to feed more frequently on birds, causing an increasing number of birds
and mosquitoes that are infected. If environmental conditions are favorable for
transmission, the virus will amplify to a theoretical point of spillover. At spillover, the
virus can bridge out of the bird-mosquito cycle through mosquitoes that feed on birds,
humans, and other animals. At the point of spillover, transmission to humans becomes
more likely. Currently, mosquito bite avoidance and mosquito control are the only
practical method of protecting the human population from WNV infection. There are no
known specific treatments or cures for the disease, and vaccines are currently not
available for public use. The virus also kills a variety of native and non-native birds, and
may have impacts on other wildlife.
Weather plays a major role in the prevalence of WNV, and the relatively warm winter
and spring experienced in North Texas during 2011 to 2012 may have been a significant
factor in the large amount of disease present during the 2012 mosquito season.
Understanding the types of mosquitoes in the area that transmit the disease is also a
crucial consideration for directing control responses and public education activities.
Since not all mosquitoes carry the virus, enacting mosquito control efforts that attempt to
non-selectively reduce all mosquito populations will not necessarily reduce the risk of
WNV. In fact, based on 15 years of mosquito monitoring and disease analyses in the
City of Denton, there appears to be only one mosquito that serves as a vector for this
disease. Approximately 94 percent of the WNV infected mosquitoes captured in
Denton’s monitoring program over the last 15 years have been Culex quinquefasciatus,
commonly known as the southern house mosquito. Approximately 99% of the
mosquitoes that have tested positive for WNV during the last 15 years of monitoring have
been some type of Culex species. Control efforts enacted by the City are therefore
focused on Culex species, and are particularly focused on Culex quinquefasciatus.
The past experience of numerous mosquito control districts suggests that a mosquito
control program should be based on the principals of Integrated Pest Management (IPM).
The principals of IPM are:
knowledge of mosquito biology and the epidemiology of the mosquito-borne
diseases;
surveillance and monitoring efforts for the detection and status assessment of
mosquito populations and / or mosquito-borne diseases;
a multifaceted prevention and control program comprised of a system of control
tactics which are compatible with each other and which are proven effective;
continue program evaluations and updates to ensure that the best methods are
being used to meet the prevention and control objectives of the program; and
continue education of the public to create awareness, understanding, and support.
These general guidelines have been used to develop the threshold-level responses of this
surveillance and response plan.

4.0 The Role of Residents
Residents can play an important role in reducing the number of adult mosquitoes by
eliminating standing water that may support the development of mosquito larva and pupa.
For example, residents can properly dispose of discarded tires, cans, buckets, maintain
pools correctly, unclog blocked gutters and drains, dump water from bird baths and pet
dishes at least every 2-3 days, ensure that air conditioning condensate is not pooling for
several days, control irrigation so that standing water is not produced, irrigate so that
runoff is not produced, and perform similar activities around homes and businesses.
Water that cannot be eliminated should be treated with a biological mosquito larvicide
such as Bacillus thuringiensis israelensis (Bti) in accordance with manufacturer’s
recommendations.
Residents should be aware that Culex quinquefasciatus, the target mosquito for control,
tends to prefer to lay its eggs in “artificial” sources of water such as those listed above, as
opposed to laying eggs in wetland areas, streams, and ponds. Generally, this mosquito
cannot fly long distances, so emerging adult mosquitoes often remain near the habitat
they lived in as larva and pupa. Adults will rest during the daytime in vegetation,
particularly in areas where humidity is high. Irrigated urban and suburban landscapes
can offer excellent habitat, especially if there is standing water present. Underground
storm drains that receive small amounts of runoff from irrigation are also good habitat for
these mosquitoes. As a result, Culex quinquefasciatus tends to become more associated
with urban and suburban areas during the summer months. Often these same areas will
also have birth baths, bird feeders, trees, and other vegetation that serve to attract birds,
especially during the drier times of the year when food and water become scarce. As a
result, the opportunities for WNV disease amplification in urban and suburban areas can
become more pronounced during summer months. The role of residents and business
owners in controlling larval habitat is therefore a crucial component of reducing local
WNV risk.
5.0 Denton’s Plan for Mosquito Surveillance
The risk of mosquito-borne diseases depends on the size of mosquito populations and the
incidence rate of disease, as well as the likelihood of the mosquito population changing in
response to climate factors. Although mosquito abundance can be estimated through
collection of either immature or adult mosquitoes, adult mosquito abundance is a key
factor contributing to the risk of virus transmission. For this reason, the City of Denton
monitoring program primarily focuses on collecting adult mosquito populations for
targeting control measures and gauging the potential for disease outbreak. The current
mosquito surveillance program is a partnership between the City of Denton and the
University of North Texas. This surveillance program collects adult mosquitoes through
the use of both CDC light traps and gravid traps. Captured mosquitoes are sent to the
Texas Department of State Health Services for testing. Each sample (sometime referred
to as a “pool”) consists of female mosquitoes that are collected at a specific collection
5
site, in one of the two types of trap. The information obtained from these surveillance
efforts is used to map mosquito populations, provide public information, and to determine
the incidence of WNV or other arbovirus.
The mosquito surveillance program allows analysts to map potential mosquito breeding
grounds and areas of persistent disease. Using this information, more targeted efforts
towards habitat disruption, source reduction, larviciding operations, and other control
mechanisms are possible. An effective, broadly applied surveillance program can allow
analysts to detect the presence of WNV of other mosquito-borne viruses during the
amplification phase. If targeted mosquito controls are implemented at the amplification
stage, the likelihood of bridging can be minimized, thus reducing the risk of human
transmission. Depending on weather patterns and monitoring results, trapping can be
expanded or contracted and the trapping season may be lengthened or shortened. If
control measures are applied, trapping data may also be of some use for evaluating the
effectiveness of control measures.
The overall goal of the mosquito surveillance program is to use data on mosquito
populations and mosquito virus infections rates to:
assess the threat of human disease;
determine the geographical areas of highest risk;
determine the need for intervention events, and the timing of these events;
identify larval habitats that are in need of targeted control;
monitor the effectiveness of control measures; and
develop a better understanding of transmission cycles and potential vector
species.
Adult surveillance methods should:
Use both fixed and flexible trap locations if possible
o Fixed positions allow for the development of a database so year to year
comparisons are possible;
o Flexible sites allow for responses to epidemiological and natural events.
Use more than one trapping method (CDC light traps, gravid traps, etc...)
o Testing data collected in the City of Denton’s monitoring program
suggests that if resource limitations require a choice between CDC light
traps or gravid traps, gravid traps are preferred. These traps have been
more effective in collecting Culex quinquefasciatus, and more effective
for establishing the prevalence of WNV.
Account for different influencing factors, including:
o Habitat size and diversity;
o Resource availability;
o Proximity to human population centers and / or recreational areas; and
o Flight ranges of target mosquito vector(s).
Advantages of using adult mosquito surveys include:
6
The ability to provide early evidence of viral activity in an area;
Helpful for determining if viral activity is local and / or restricted to a few areas;
Providing information on potential mosquito vector species
Providing estimates of vector species abundance and temporal prevalence;
Providing information on virus infection rates for different mosquito species;
Providing information on potential risks to humans and animals;
Providing baseline data that can be used to guide emergency controls.
Disadvantages of using adult mosquito surveys include:
The amount of labor required, and associated expenses;
The need for substantial expertise to ensure proper collection and handling of
mosquitoes;
The delays associated with receiving mosquito arbovirus screening results;
The fact that collectors may be at risk from mosquito bites (although using
personal protection methods can minimize risks).
5.1 Adult mosquito collection
The adult mosquito surveys implemented by the City of Denton in conjunction with the
University of North Texas are designed to determine the relative abundance of various
species present during the sampling period as well as the incidence of arthropod-borne
virus/diseases within the captured specimens. Using this information, City of Denton
personnel determines the need for various control measures, and can conduct more
effective searches for larval breeding places, assess the extent of the problem, and
potentially gauge the effectiveness of control measures. Reports concerning the
incidence rates of arthropod-borne virus/diseases and the relative risks to citizens are also
produced. Currently, collections are made using both CDC light traps and gravid traps
deployed simultaneously.
6.0 Mosquito Control Strategies
Human activities can greatly affect the ecology of mosquito populations. Large
concentrations of people or animals, for example, can increase exposure rates and the
probability of disease outbreak. The use of irrigation, development of drainage networks,
elimination of mosquito predators, prevalence of improperly maintained birdbaths and
other water holding containers can increase the numbers of certain types of mosquitoes.
Expanding international trade and travel has increased the chance of introducing new
mosquito species into our areas, as has happened with the Asian tiger mosquito (Aedes
albopictus). The introduction of new diseases is also a concern, as has been seen recently
with both Chikungunya and Zika viruses.
Mosquito control strategies have changed dramatically over the last few decades. Diesel
oil, inorganic poisons, and source reduction using ditching operations were the basic tools
of early mosquito control programs. Chlorinated hydrocarbons, organophosphates,
7
pyrethroids, monomolecular oils, bacteria, and natural predators are more recent
additions to mosquito control efforts. With the growth of ecological consciousness and
environmental science, people began to realize the environmental damage that
accompanied the use of broad-spectrum chemical control agents, particularly those that
did not readily break down in nature. Concerns were also raised because many mosquito
populations also appeared to develop resistance to the more commonly used chemical
control agents.
Over the past few years, major advances have been made in the areas of biological
mosquito control. Biological control strategies may include using natural predators like
Gambusia affinis (Mosquito fish), fungi, protozoans, round worms, flat worms, and
bacterial agents such as Bacillus thuringiensis israelensis (Bti). Each biological control
agent has certain benefits and restrictions. In order to use a biological control agent
successfully, the applicator must have a basic knowledge of biology associated with the
control agent. Some biological control mechanisms, for example, are limited by salinity,
temperature, or organic pollution and some mosquito species are much more susceptible
to specific types of biological control agents. All of these factors must be considered
when choosing and applying biological control agents.
The perfect pesticide is one that is easily applied, reasonably inexpensive, not toxic to
non-target organisms, and that eliminates the pest quickly before it becomes a threat.
Although no single pesticide can combine all of these factors, certain types of Bacillus
bacteria have been developed into pesticides that are very close to the perfect pesticide
model. Bacillus thuringiensis israelensis (Bti), for example, is a naturally occurring soil
bacterium that produces a poison capable of killing mosquito larvae. Bti is considered
ideal for mosquito management because of its specificity for mosquito larvae and because
of the minimal to no toxicity to non-target organisms. These bacteria form reproductive
cells, called endospores, which enable them to survive in adverse conditions. The
endospores of Bti also contain crystals of an insecticidal protein toxin called delta
endotoxin. Once ingested by a mosquito, the alkaline conditions of the stomach dissolve
the crystal and release the delta-endotoxin. The toxin has an affinity for the stomach wall
lining causing the cells to first swell then rupture. When enough stomach cells burst, the
mosquito larvae is unable to effectively digest food. Once affected, larvae stop eating
and rapidly die. Currently, Bti is commercially available in powder, liquid, granular,
capsule, and “briquette” formulations.
Agencies applying pesticides directly to waters of the United States, or where deposition
may enter waters of the United States, are required to obtain a National Pollutant
Discharge Elimination System (NPDES) permit from the Texas Commission on
Environmental Quality (TCEQ). This permit is titled “General Permit to Authorize Point
Source Discharge of Biological Pesticides and Chemical Pesticides That Leave a Residue
in Water”. Agencies must comply with all applicable provisions of this permit (see
TCEQ General Permit TXG87000). The City of Denton complies with all requirements
necessary to maintain the City’s permit under TXG87000.

6.1 Larviciding vs. Adulticiding
In the past, many mosquito control programs have relied heavily upon adult mosquito
controls using chemical agents. In certain areas, routine mosquito spraying has been an
integral component of control strategies. However, even near-continuous exposures to
pesticides may not kill all mosquitoes. Those mosquitoes genetically able to resist higher
pesticide concentrations may survive and pass on this resistance to future generations.
Eventually, the pesticide becomes less effective as resistance increases in the mosquito
populations.
Resistance can be minimized through the "Management by Moderation" approach.
Management by moderation is an attempt to prevent the onset of resistance by:
using doses that are no lower than the lowest recommended application rate to
avoid genetic selection of resistance genes;
using less frequent applications;
using chemicals of short environmental persistence;
avoiding the use of slow release formulations;
avoiding using the same class of pesticides to control both adults and immature
stages;
applying pesticides to only hot spots. Area-wide treatments should only be
considered during imminent public health threats;
leaving certain generations, populations, or population segments untreated; and
establishing action thresholds that accentuate control mechanisms other than
chemical control of adult mosquitoes.
Although management by moderation is a viable means of minimizing resistance, there
are other environmental and human health concerns associated with the application of
pesticides for adult mosquito control. Routine mosquito spraying, for example, has the
potential to expose the public to pesticides. Depending upon the pesticide used, effects
on humans are possible and may be more likely for people who already suffer from
asthma or other respiratory problems. If proper safety precautions are not followed,
applicator personnel may also be in danger of overexposure. Managers must therefore
decide whether mosquito populations and the related threat of disease transmission or the
chemicals used to control mosquitoes represent the bigger threat to humans.
All mosquitoes begin their lives in water. Prime breeding sites include discarded tires
left outdoors, poorly maintained bird baths, clogged rain gutters, unused swimming pools
and plastic wading pools, pet dishes, or any other container capable of holding water for
more than a few days. Mosquito breeding can therefore be prevented by either
eliminating the source of water (source reduction) or by killing larvae (larviciding).
Larviciding programs use a combination of source reduction, biological, and possibly
chemical measures to control mosquito larvae before they develop into biting adults. If
properly implemented, this strategy can be the most effective, economical and safest
method for mosquito control because mosquito larvae are minimized, thus reducing the
need for adult mosquito control and subsequently reducing the impacts of control
9
measures on non-target organisms. Larviciding programs also offer the opportunity to
use biological controls, which minimizes the impacts of the control program on non-
target organisms and lessens the risk of chemical exposures to the public. Using
biological controls also minimizes the chance of pesticide resistance in the mosquito
populations. Experience suggests that the most effective and economical way to reduce
mosquito populations is by larval source reduction through a locally funded abatement
program. The goal of this program should be to monitor mosquito populations and
initiate controls before diseases are transmitted to humans or domestic animals (CDC,
2001).
When larval control is not possible or more immediate control measures are needed, adult
mosquito control may be required to diminish populations of infected mosquitoes and
interrupt viral transmission. Adult mosquito control products may be applied using
ground based equipment, fixed wing aircraft, or helicopters. In all cases, products
should be applied in ultralow volume (ULV) formulations and doses, and should be
comprised of pyrethroids.
6.2 Rationale for different treatment methods
Chemical usage should not be viewed as a long-term control strategy, and should be only
implemented when there are occasional episodes of heavy uncontrolled breeding
concurrent with a high degree of public health risk. This strategy is most appropriate
because prolonged use might lead to the development of resistance in mosquito
populations, thereby limiting overall management options (Tabashnik, 1990). The most
efficient and effective program is one in which mosquito larvae are prevented from
becoming biting adults through the use of biological control agents. The bacterium Bti or
the related bacterium Bacillus sphaericus (Bs.) are considered to be the among the most
environmentally acceptable commercially available biological control agents because of
their relative specificity for mosquitoes and negligible toxicity for vertebrates (Rishikesh
et al., 1983). Larvivorous fish can also be a valuable component of an integrated control
program, either alone or together with chemical control agents (Walton et al., 1990;
Walton and Mulla, 1991; Reed et al., 1995). For these reasons, the City of Denton relies
heavily on source reduction and larviciding for mosquito control.
6.3 Integrated Pest Management
Integrated pest management dictates that control efforts should be dependent on threshold
levels. This means simply that a certain defined risk needs to exist before particular
control measures are recommended. Levels of risk are based on knowledge of mosquito
biology, the epidemiology of the mosquito-borne diseases, and monitoring efforts for the
status assessment of mosquitoes and / or mosquito-borne diseases. Risks levels are then
used to design multi-tactic prevention and control program that are comprised of a system
of tactics which are compatible with each other and which are proven for their
10
effectiveness. Continual program evaluations and updates ensure that the best methods
are being used to meet the prevention and control objectives of the program, and
continued public education is used to create awareness, understanding, and support.
Frequent mosquito population assessments allow analysts to map potential mosquito
breeding grounds and determine overall disease transmission risks. Using this
information, more targeted efforts towards habitat disruption, source reduction,
larviciding operations, and other control mechanisms are possible.
7.0 Denton's Plan for Mosquito Control
The primary objective of mosquito control is to decrease the risk of mosquito-borne
human diseases. This objective should be accomplished by:
Stressing source reduction as a viable means of control, both by residents and on
municipal properties, including enforcement actions for stagnant water located
on private property;
Aggressively larviciding where such activities are feasible, practical, and likely
to be effective. This includes providing limited supplies of larvicides to citizens
for use on private property.
Promoting the use of personal mosquito protection measures, especially for the
elderly and those individuals with compromised immune systems, through
public education and outreach.
Providing public information so that citizens are informed about the current Risk
Level, areas of the City where WNV has been located, current municipal control
measures, and what can be done by the public to help reduce risks.
If warranted, implement adult mosquito control measures through targeted ULV
pesticide applications (adulticiding).
7.1 Adulticiding
Adulticiding should and will be considered a supplemental control measure. The
decision to spray shall be based on the conditions listed (in no particular order) below.
7.1.1 Triggers for adulticides: Adulticiding shall be considered only when there is
evidence of WNV activity at a level suggesting a high probability of human infection. In
general, finding an isolated WNV-positive mosquito pool does not by itself constitute
evidence of an imminent threat to human health and does not warrant adulticiding.
Physicians and laboratories are required by Title 25 of the Texas Administrative Code
(Pt. 1, Ch. 97, Subch A, §97.3) to report cases of WNV infection or positive test results in
humans to the State and County Health Departments. Positive human WNV cases are
investigated by Health Department officials. During an investigation, the Health
Department collects demographic and clinical information from the patient and attempts
to determine date of onset, whether the infection was acquired locally or from a region
outside of the patient’s residence, and whether the infection may have been acquired by a
11
non-mosquito route of transmission such as a blood transfusion or organ transplant. To
help aid control measures, the Health Department provides some of this information to
municipal officials within the municipality where the patient resides. Human case
information is used by municipal officials as one of the trigger conditions for the risk
levels outlined in this plan
7.1.2 When to use adulticides: The goal of spraying is to reduce the risk of human
diseases by decreasing the number of target adult mosquitoes as much as possible.
However, today’s pesticides tend to only be effective when physically contacting the
mosquito, which is most likely to happen when mosquitoes are actively flying. This
typically will mean that spraying should be conducted between dusk and dawn. Since
the target mosquito, Culex quinquefasciatus, is thought to be most active soon after dusk,
spraying should be timed to strike the best balance between impacting the target
mosquito during its most active time and minimizing impacts on non-target organisms.
It is also important to realize that weather conditions, including air temperature and wind
speed, have a large influence on the effectiveness of adulticides. Spray events should be
cancelled and rescheduled if conditions are not conducive for effective spraying.
7.1.3 Where to use adulticides: The terrain of the proposed spraying area has a major
impact on the pesticide effectiveness. If there is substantial vegetation, dense shrubbery,
trees, or hedges, pesticide applications can be rendered ineffective. The density of
houses and other physical obstructions can also influence the effectiveness of pesticides.
Applications should be made so that the maximum penetration into these types of
obstructions is achieved. In some cases, a mild breeze may be able to help distribute the
pesticide. Application strategies should consider the meteorological conditions at the
time of application, and use these conditions to help improve application effectiveness if
possible.
7.1.4 Human population density considerations: The human population density in an
area where there is evidence of intense epizootic activity should also be considered. If
the area in question is rural and does not contain many people, the cost and potential risk
associated with spraying may not justify its use. If the area in question is densely
populated, adult mosquito control may be more justified as long as adequate
precautionary measures are taken.
7.1.5 Mosquito population considerations: Information from mosquito surveillance
can be helpful in determining when to conduct mosquito control and to assess the
effectiveness of control measures. It is also important to know the numbers and species
of the vector populations in specific localities. The best way to obtain this information is
through mosquito trapping efforts. The City of Denton formed a partnership with the
University of North Texas to provide the specially trained staff needed for systematic
mosquito trapping efforts.
While trapping efforts are crucial for assessing mosquito populations and the prevalence
of disease, it is important to realize that surveillance specimens requires some processing
time after collection. In the time between the collection date and the date of test results,
12
circumstances may have occurred which would alter a decision to spray. For example,
weather conditions may have adversely affected mosquito populations, local mosquito
habitats may have been altered, or larviciding efforts may have reduced the number of
newly emerged adults. All of these occurrences may result in a reduced need to spray,
and should be taken into consideration during control efforts.
Surveillance information should also be evaluated through time to determine the progress
of diseases and the relative risk of disease transmission. Surveillance information may
also be of some use in gauging the effectiveness of control measures, although
establishing control effectiveness is difficult using only surveillance information. In all
cases, the available surveillance information should be evaluated as a part of the decision
making process for enacting adulticidal activities.
7.1.6 Local perspectives on spraying: Different communities have different
perspectives on the benefits and risks associated with adulticiding activities. While these
perspectives are valid and should be considered, individuals are likely to have strong
opinions on either side of the issue. The City of Denton has incorporated a rationale
framework within the mosquito control program that is designed to be protective of both
human health and the environment. The decision to spray, however, is a complex issue
that will likely be faced without complete information. Thus, there will be citizens that
do not believe that the City of Denton has done a good job with regards to reducing
public health and environmental risks, regardless of the decision. The mosquito control
program should therefore remain flexible and should attempt to address citizen
complaints through public education and dialogue.
7.1.7 Denton's plan for mosquito adulticiding operations
Once arbovirus activity is detected and the decision is made to implement mosquito
control using adulticides, the size of the area to treat must be determined. Unfortunately,
there is no simple formula for determining how large of an area to treat, nor is there
adequate information to guide decisions about the degree of vector population
suppression that must be attained, or for how long this suppression must be maintained to
reduce the risk of disease. The CDC (2001) suggests considering the following factors
where deciding the scope of the adulticiding effort:
the general ecology of the area;
the flight range of vectors that are known or are believed to be of importance in
the area;
the population density of the vectors;
the length of time since virus-positive mosquito pools were collected;
the potential risk to the human population (including the age demographics of the
area) as well as the community perception of the relative risk of pesticides versus
the risk of arbovirus infection; and
the season of the year - how much time the transmission risk can be expected to
persist until the vectors enter diapause;
13
It is very likely that some of these factors will be unknown or poorly known, and
practical experience in conducting a mosquito control program is needed to refine control
recommendations. If adulticiding operations are conducted, the following parameters
should be monitored:
Weather conditions during the application (temperature, wind speed, wind
direction, etc...);
Flow rate of Ultra-Low Volume applications; and
Overall amount of pesticide applied.
If the application of adulticides is deemed necessary, the public must be informed. The
following actions / activities will take place prior to adulticide applications:
Information, including a map of the proposed spray area, will be released 24
hours in advance through the media and through the city of Denton web site.
Under certain conditions in Public Park areas, applications may take place in less
than 24 hours notice. For these cases, the facility will be closed to the public
during, and a few hours after, application.
Press releases should be prepared and shared with the appropriate media
CodeRed, the Customer Service automated calling systems, and available forms
of social media should be used to inform citizens of spray events. CodeRed will
make an automated phone call with a message to all individuals that have signed
up for the service. The Customer Service automated calling system will make an
automated phone call with a message to all individuals within an area designed
by the spray map. For both systems, it is possible that some residents outside of
the spray area will receive one of these calls. However, these systems are the
most rapid and accurate means of notifying the public of upcoming spray events.
If practical, street signs indicating that spraying will occur in the neighborhood
should be placed at major roadways entering and exiting the targeted area.
7.2 Plan for Public Education Concerning Mosquitoes
Public education is a key component of a successful mosquito control program. Since
the appearance of the West Nile Virus in the United States, the City of Denton has
produced and aired many public service announcements, given numerous presentations,
and provides information on the City web page concerning this disease. Depending
somewhat on Risk level, the following key information will be conveyed to the public:
The location of WNV positive mosquito trap locations and current risk level;
Comprehensive prevention strategies and activities used by the City of Denton to
address the threat of West Nile Virus;
The public will be advised to eliminate standing water sites by removing all
materials that can hold water for longer than 2-3 days; and
14
The public will be informed about the symptoms of West Nile Virus (headache,
high fever, muscle pain, weakness, and disorientation).
Techniques used to disseminate information may include any or all of the following:
Televised public service announcements using Denton's local cable channel;
Radio announcements;
Brochures for public use placed in municipal buildings;
Postings describing the current risk level placed in municipal buildings;
Brochures and / or fact sheets to be distributed to community-based organizations,
community boards, elected officials, schools, nursing homes, libraries, outdoor
activity sites, etc.;
Presentations to elected officials and / or community groups concerning the
current risk level, mosquito population and disease status, and mosquito control
activities; and
Press releases describing West Nile virus response activities.
7.3 City of Denton Response Plan
The purpose of this response plan is to:
1. Minimize human illness through public education and targeted vector
control.
2. Provide an assessment of virus transmission risk to humans that can be
used to plan and adjust control activities.
3. Map the density of mosquitoes and the incidence of the virus within the
City of Denton.
4. Identify areas where the incidence of disease is high and provide
appropriate warnings to the citizens of Denton.
5. Identify the key vector species that carry diseases within Denton.
The prevention of West Nile virus, as with many diseases, is most efficiently
accomplished by ensuring that prompt, accurate information reaches the public. If the
appropriate information reaches the public in a timely manner, personal protective
measures may be implemented, and control strategies can be enacted efficiently.
The City of Denton will provide continuous information on the city web page concerning
West Nile virus, including a frequently asked questions (FAQs) section, disease
symptoms, personal preventative measures, and sources of additional information. If a
sampled mosquito pool tests positive for arthropod-borne virus/diseases, information
describing the location of the sampling event, the date, and other pertinent information
will be provided.
15
This response plan is partially based on Texas Department of Health recommendations.
The plan is divided into 5 levels based on the risk of human disease. Each risk level is
described below, along with specific recommended responses. In accordance with the
principals of Integrated Pest Management Control measures are recommended for each
level.
Generally, there are 4 surveillance / observational factors that are evaluated to determine
if the trigger condition has been met for a particular risk level. These factors are:
1. Environmental / climatic conditions (mainly temperature, rainfall, and season)
2. Adult Culex quinquefasciatus abundance
3. Virus infection rates in Culex quinquefasciatus and other mosquito vectors
4 Confirmed infections in humans, including epidemiological information.
7.3.1 Risk level 1 - Normal Response
Condition: Probability of human outbreak is none or remote
Trigger: Normal mosquito activity with no evidence of arthropod-borne
virus/disease detected during the past 3 years in vectors, humans, or other
hosts.
Recommended Response:
Surveillance:
Surveillance is optional. Under the normal response, mosquitoes are considered to be
only a nuisance without significant influences on public health. Complaint calls and
informal surveys of larva and adults will be used to direct mosquito control efforts.
Public Information / Education:
Publicize methods for mosquito reduction and personal protection prior to the main
season for mosquito activity and outdoor human activities.
Control Measures
Use public information to promote source reduction and personal protection. Conduct
standard larviciding approaches using Bacillus thuringiensis israelensis (Bti) .
Rationale:
Larviciding and source reduction / elimination are considered to be the most effective
long-term solutions for mosquito control. The control measures are designed to
accomplish mosquito control by preventing larval mosquitoes from becoming biting
adults.
16
7.3.2 Risk Level 2 - Enhanced Response
Condition: Probability of human outbreak is low
Trigger: Normal mosquito activity with little or no evidence of arthropod-borne
virus/disease. Enhanced response level is due to recent historical presence
of arthropod-borne virus/disease in vectors, humans, or other hosts within
the vicinity of Denton (approximately 100 miles).
Recommended Response:
Surveillance:
Surveillance is optional, but strongly encouraged. If possible, conduct routine
surveillance of adult mosquito populations using light traps baited with CO2 and gravid
traps (at minimum). Collected mosquito species should be identified to species level and
mosquito pools should be screened for the presence of arboviruses. If positive tests are
obtained during arthropod-borne virus/disease screening, additional tests should be
performed to determine what type of arbovirus is present.
Public Information / Education:
Implement all steps for public information established by the Public Communication
Office for this Risk Level. Generally, this will reflect routine public information
concerning methods for mosquito reduction and the importance of personal protection
measures. This information should be disseminated at the beginning of the mosquito
season.
Control Measures
Use public information to promote source reduction and personal protection. Conduct
standard larviciding approaches using Bacillus thuringiensis israelensis (Bti).
Rationale:
Larviciding and source reduction / elimination are considered to be the most effective
long-term solutions for mosquito control. The control measures are designed to
accomplish mosquito control by preventing larval mosquitoes from becoming biting
adults.
17
7.3.3 Risk Level 3 - Public Health Concern
Condition: Probability of human outbreak is low to moderate
Trigger: Arthropod-borne virus/disease isolated from mosquitoes collected during
trapping activities at a single monitoring site.
Recommended Response:
Surveillance:
Continue to conduct routine surveillance of mosquito populations. If resources allow,
increase surveillance in the area where the positive sample was collected. Use
geographic information systems to plot the location of the positive sample and provide
this information to the public via the City of Denton web page.
Public Information / Education:
Implement all steps for public information established by the Public Communication
Office for this Risk Level, which includes public notification, press releases, and City of
Denton web page updates with a map of the positive trap location. Notify medical
professionals, veterinarians, and all those registered with the City of Denton’s various
public notification options of the presence of the disease.
Control Measures
Use public information to promote source reduction and personal protection. Conduct
enhanced larviciding using Bacillus thuringiensis israelensis (Bti). Increase efforts in
areas where positive mosquito pools were detected. Control measures will be
implemented based on the following IPM criteria: time of year, the extent of previous
mosquito control activities, the current level of mosquito activity, weather conditions, and
surveillance results.
Prepare for ground level spraying activities using ULV applications of pyrethriods.
Ensure adequate funding and personnel are in place for conducting ULV applications.
Rationale:
Larviciding and source reduction / elimination are considered to be the most effective
long-term solution for mosquito control. Increasing these measures in areas where
positive mosquito pools are detected offers an additional degree of risk reduction.
18
7.3.4 Risk Level 4 - Public Health Warning
Condition: Probability of human outbreak is moderate to high
Trigger: Multiple mosquito pools collected at different times and locations test
positive for arthropod-borne virus/diseases.
Single human case confirmed with laboratory testing
Recommended Response:
Surveillance:
Continue to conduct routine surveillance of mosquito populations. Increase surveillance
in areas where WNV positive samples have been collected if resources are available. Use
geographic information systems to plot the location of positive mosquito samples and
provide this information to the public via the City of Denton web page.
Public Information / Education:
Implement all steps for public information established by the Public
Communication Office for this Risk Level, which includes public notification,
press releases, and City of Denton web page updates with a map of the WNV
positive trap location(s).
Update web page map for all subsequent WNV positive trap locations
Notify medical professionals, veterinarians, public health officials, and all those
registered with the City of Denton’s various public notification options of the
presence of the disease.
Control Measures
Use public information to promote source reduction and personal protection. Intensify
enhanced larviciding efforts using Bti in targeted areas. Consider using Spinosad
products in areas where positive mosquito pools were detected, if applicable. Control
measures will be implemented based on the following IPM criteria: time of year, the
extent of previous mosquito control activities, the current level of mosquito activity,
weather conditions, and surveillance results.
Finalize all actions needed for implementing ground level spraying activities using ULV
applications of pyrethroids
Rationale:
Larviciding and source reduction / elimination are considered to be the most effective
long-term solutions for mosquito control. Increasing these measures in areas where
positive mosquito pools are detected offers an additional degree of risk reduction.
19
7.3.5 Risk Level 5 - Public Health Alert
Condition: Human outbreak is confirmed
Trigger: Multiple human cases. Cases must be confirmed by laboratory testing.
Recommended Response:
Surveillance:
Continue to conduct routine surveillance of mosquito populations. If resources allow,
increase surveillance in areas were arthropod-borne virus/disease positive samples were
collected. Use geographic information systems to plot the location of WNV positive
mosquito samples, and provide this information to the public.
Public Information/Education:
Implement all steps for public information established by the Public
Communication Office for this Risk Level, which includes public notification,
press releases, and City of Denton web page updates with a map of the WNV
positive trap location(s).
Update web page map for all subsequent WNV positive trap locations
Notify medical professionals, veterinarians, public health officials, and all those
registered with the City of Denton’s various public notification options of the
presence of the disease.
Increase public education, emphasizing source reduction, personal protection, and
disease symptoms.
Control Measures:
Use public information to promote source reduction and personal protection. Intensify
larviciding efforts using Bti in targeted areas. Additional larvicides containing IGRs or
pesticides such as Spinosad may be applied at this time. Intensely treat standing water in
City Parks. If the threat to human health is considered imminent, consider targeted
adulticide applications using ground-based Ultra-Low Volume (ULV) equipment. The
decision to spray will be made by a Resolution of the City Council of Denton prior to the
first application, for each mosquito season. Based on information available at the time
of the Council decision, the Resolution may include specific requirements in addition
those outlined in this plan. ULV applications should be implemented in the vicinity
(approximately 1 mile) of areas where positive human cases were detected. When ULV
applications are initiated, notification will be provided to the public as outlined in Section
7.1.
During 2012, the City of Denton utilized Duet, a synthetic pyrethroid product with an
additional chemical designed to induce “benign agitation” of mosquitoes. The purpose
of benign agitation is to increase the likelihood of mosquitoes flying during the
application, which increases application effectiveness. The Duet product is also mineral
oil based, versus water based, which likely increases the compound’s effectiveness in the
20
higher air temperatures typical during summer applications. Mineral oil based
compounds may also be less likely to affect non-target organisms in aquatic
environments because of the lack of solubility of the oil based compound in water.
Control measures will be implemented based on the following IPM criteria: time of year,
the extent of previous mosquito control activities, the current level of mosquito activity,
weather conditions, the species of mosquitoes that test positive for disease, the number of
local mosquito pools which test positively for disease, the likely time until a killing frost,
the density of roads or other access to mosquito breeding grounds, and the density of
human populations. Epidemiological data associated with reported human cases of
WNV will also be considered. In general, if an area has been sprayed, that area will not
be sprayed again in response to an additional human case unless the date of onset of the
new case indicates exposure occurred after the previous spraying event. Areas will also
not be sprayed in response to a reported human case if epidemiological information
clearly indicates that exposure did not occur in the City of Denton. If public health
emergencies are declared at the county or state level, the recommended responses
associated with the declaration will take precedence over the control plan of the City of
Denton.
Rationale:
Larviciding and source reduction/elimination are considered to be the most effective
long-term solutions for mosquito control. Increasing these measures in areas where
positive mosquito pools are detected offers an additional degree of risk reduction.
However, at this Risk Level, applications of adulticides may be needed to rapidly reduce
mosquito populations and halt disease transmission. The objective is to kill a high enough
proportion of older adult mosquitoes to break the disease transmission cycle. If adult
mosquito controls are implemented, the approaches for adulticiding outlined in this plan
are effective and are designed to minimize adverse effects to the environment and non-
target organisms.
8.0 Emerging Diseases
In recent years, mosquito-borne viruses from other areas of the world have caused
outbreaks in the Western Hemisphere. In addition, mosquito-borne viruses that have
been restricted to the tropics for the last several decades are beginning to move
northwards, and could cause concerns for outbreaks in the southern portions of the United
States. Chikungunya virus, for example, has become firmly established in the
Caribbean, and two cases of locally-transmitted Chikungunya virus were observed in
Florida in 2014. Dengue is a serious arboviral disease of the Americas, Asia and Africa
that has become more common in south Texas and the Florida Keys in recent years.
Zika virus has been responsible for outbreaks in tropical areas throughout the world, and
was found in 2015 for the first time in the Western Hemisphere. The rapid spread of this
disease and the possibility of transmission from human to human without mosquito
vectors is particularly troubling. To date, local transmission of Zika virus in Texas has
21
only been documented in Brownsville. However, the City of Denton has experienced
human cases of Zika virus, and has developed a response protocol in coordination with
the Denton County Public Health Department to ensure that appropriate measures are
taken to minimize the likelihood of transmission of the virus from the infected person to
local mosquito populations. The City of Denton also documented two cases of
California Seropositive viruses (a group of viruses, some of which can cause human
disease) in mosquito samples collected in 2016. These samples were later confirmed to
be trivittatus virus. While all mammals including humans are capable of contracting
trivittatus virus from the bite of an infected mosquito, this disease is predominately found
in wildlife, and human cases are extremely rare. It is important to note that both Zika
and trivitattus virus are spread by only a few species of mosquito, and control measures
must be specifically targeted to these species. In response to these emerging concerns,
City of Denton staff continues to work with local and State public health personnel to
assess the risk of disease and coordinate responses. Currently, emerging disease
responses are documented within Standard Operating Procedures (SOPs) that are
reviewed with local health officials and mosquito control experts on a regular basis.
Modifications to the SOPs are possible more research is conducted on control strategies
and risk minimization measures. As more information is collected and evaluated, it is
likely that the City of Denton Mosquito Surveillance and Response Plan will be modified
in the future to add information specific to these emerging diseases.

MEMORANDUM
DATE: April 2, 2018
TO: Deborah Viera, Assistant Director of Environmental Services
Kenneth Banks, General Manager Utilities
FROM: Jessica Rogers, Deputy Director of Public Affairs/PIO
CC: Sarah Kuechler, Director of Public Affairs/IGR
SUBJECT: 2018 Educational Campaign and Notification Plan for Mosquito Control and
Surveillance/Response
Plan Subject
Public education and notification is a key component of a successful mosquito-control program.
This communication plan addresses the need to inform the citizens of Denton about mosquito-
control measures and the possibility of a West Nile virus (WNV) outbreak, and to get citizens
involved in the solution. This plan correlates with updates from the 2017 City of Denton
Mosquito Surveillance and Response Plan prepared by Kenneth Banks, Director of Utilities.
Each of the five risk levels and corresponding public education and notification activities are
outlined in this plan.
Scope of Plan
Since the appearance of WNV in the United States, the City of Denton has produced and
distributed various communications assets and resources; released numerous news items and
conducted many media interviews; provided detailed information and resources about the disease
and mosquito-control activities on the City’s website; and directed traffic to the website using
social media, print and digital ads, the utility bill newsletter, and DTV videos. When feasible,
because of potential health risks, this information was translated to Spanish.
In the last couple of years, the Public Communications Office (PCO) made updates to all the
education materials. The “Fight the Bite” educational campaign centers around three main
themes: source reduction, personal protection, and disease symptoms. Materials also emphasize
City activities and surveillance findings. The plan is flexible and allows messages and
educational outlets to change as the risk level increases or decreases.
During this time, Denton County has been more involved in mosquito control and WNV
education and has developed its own campaign for cities in Denton County. PCO staff works
with Denton County to ensure City information is consistent and to help avoid message
confusion. PCO would take the same approach with Zika and Chickungunya viruses, which may
become important mosquito-borne diseases for Denton County in the future.
Public Communications Office
215 E. McKinney St., Denton, TX 76201 (940) 349-8172
Timeline
The initial “Fight the Bite” educational campaign begins in April or May, and a baseline
campaign will run until the mosquito season has passed, typically in November. Individual
notification efforts, corresponding with the five risk levels, will be enacted as needed, as will
spraying notification efforts.
Audiences
Depending on which risk level Denton is operating under, audiences range from the community
at large to specific neighborhoods, contingent on the situation and problems identified. All risk
levels have provisions for general public notification efforts. An effort will be made to produce
as much of the educational campaign as possible in Spanish. Internal methods of communication,
such as the City of Denton employee newsletter and email system, will be utilized to help keep
employees knowledgeable concerning the mosquito and WNV situation.
General Educational and Notification Methods and Materials
Website – All information will be placed on the City’s website, www.cityofdenton.com.
Email notifications to subscribers will also be utilized.
Media – News releases/media updates will be sent to all local media including
newspaper, radio, and television. All news releases are placed on the City’s website at
www.cityofdenton.com.
Print and Digital Ads – Ads will be placed in the Denton Record-Chronicle (DRC), as
well as on the DRC web and mobile sites.
Social Media – The City’s main Facebook page, Twitter account, and YouTube channel
will be used to reach a wide audience.
Displays – Printed assets, such as posters and brochures, will be available at Utilities
Customer Service, the libraries and recreation centers, and other public facilities.
Newsletters – The Denton Citizen Connection (the utility bill newsletter) and the internal
employee newsletter will be utilized to provide source reduction and protection
information.
Public Outreach – Denton environmental clubs, various civic groups, and neighborhood
associations will be solicited for speaking engagement opportunities. The City will also
work with neighborhood associations to help reach homeowners. Area-specific
information may be delivered to specific neighborhoods through brochures, posters, and
community newsletters.
Television – A bulletin board system (BBS) message will be placed on DTV. Mosquito-
control issues will also be featured on the City’s news program, DTV NewsBreak.
Translated Materials: A portion of the web information, posters, and program
informational brochures will be produced in Spanish.
Roles and Responsibilities
PCO will produce the communication plan and materials, help facilitate media coverage, place
print and digital ads, and coordinate the distribution of assets. The Director of Utilities will

Mayor’s Day of Concern for the Hungry
Food Drive and Donations Collected May 7-11
DENTON, TX, May 1, 2018 – Mayor Chris Watts announced the Mayor’s Day of Concern for
the Hungry food drive at tonight’s City Council meeting. This is the seventh year of the event
encouraging residents and businesses in Denton to help address hunger in the community with a
one-week food collection drive from May 7-11.
More than 159,257 people in Denton County struggle with food insecurity, which means they do
not know where their next meal will come from. In the Denton Independent School District
alone, there are 11,362 students who are on free lunches and 1,786 students who are on reduced-
priced lunches, which means 44% of the student population is on free or reduced lunches.
Every resident and business in Denton can help address hunger by dropping food donations from
May 7-11 at participating business and non-profit locations throughout the city, which are
available online at www.UnitedWayDenton.org/MDOC. This is also the first year that monetary
donations will be accepted online. Food pantries are able to make each dollar go further by
purchasing in bulk through existing partnerships. Every $1 donated buys 3 pounds of food.
The Mayor's Day of Concern is a collaborative effort between City of Denton Mayor Chris Watts
and a large team of local organizations including the Denton Hunger Coalition, Denton
Community Food Center, Denton Community Market, Denton County Friends of the Family,
Denton County MHMR Center, Denton Hunger Coalition, First Refuge Ministries, Health
Services of North Texas, Our Daily Bread, NCTC Corinth Campus, The Salvation Army of
Denton, Vision Ministries, and United Way of Denton County.
Results from the drive will be announced at the Mayor’s Day of Concern at the Denton
Community Market on Saturday, May 19 at 11 a.m.

NOTICE OF PUBLIC MEETING
Farm To Market Road 1173 from Farm to Market Road 156 to Interstate Highway 35
Denton County, Texas
CSJ No. 1059-01-047
The Texas Department of Transportation (TxDOT) will conduct a Public Meeting for the purpose of soliciting public
comments on proposed feasibility study of Farm to Market Road (FM) 1173 from FM 156 (S. 1st Street) to
Interstate Highway (IH) 35, a distance of approximately 3.6 miles. The meeting will be held on Tuesday, May 8,
2018 at the Krum High School Cafeteria, located at 700 Bobcat Blvd, Krum, TX 76249.
The Public Meeting will be an Open House format with no formal presentation from 6:00 p.m. to 8:00 p.m. The
purpose of the meeting is to present the planned improvements and to receive public comment on the proposed
project. Representatives from TxDOT and project consultants will be available to answer questions about the
proposed project.
The proposed study consists of the reconstruction and widening of FM 1173 from FM 156 in Krum, to IH 35 in
Denton, TX. The improvements would include the expansion of the current 2-lane rural roadway to a 6-lane urban
roadway. Expansion would consist of one 12-foot wide travel lane and one 14-foot wide outside shared-use lane
in each direction, a proposed median, and sidewalks located along the outside of both the eastbound and
westbound lanes. The existing right-of-way (ROW) width is 80 feet and will increase with the proposed
project. The proposed ROW is anticipated to acquire approximately 43 acres to expand the roadway, based on
this preliminary level of design.
Maps showing the proposed project’s location and geometric design will be available for viewing at the public
meeting. This information will also be on file and available for inspection Monday through Friday between the
hours of 8:00 a.m. and 5 p.m. at the TxDOT Dallas District Office, 4777 E. Highway 80, Mesquite, TX 75150 and
the TxDOT Denton County Area Office located at 2624 W. Prairie Street, Denton, TX 76201. Project information
also will be available online at www.keepitmovingdallas.com under Upcoming Public Hearings/Meetings.
All interested persons are invited to attend this Public Meeting. Written comments from the public are requested
and will be accepted for a period of 15 calendar days following the meeting. Written comments may be submitted
either in person at the public meeting, by mail to the TxDOT Dallas District Office, Attention: Mr. Nelson
Underwood, P.E., 4777 E. Highway 80, Mesquite, TX 75150-6643, or by email addressed to
nelson.underwood@txdot.gov. Written comments must be postmarked by May 23, 2018, to be included in the
Public Meeting Summary.
Persons interested in attending this meeting who have special communication or accommodation needs are
encouraged to contact the TxDOT Dallas District Public Information Office at (214) 320‐4480 at least two working
days prior to the meeting. Because the Public Meeting will be conducted in English, any requests for language
interpreters or other special communication needs should also be made at least two (2) days prior to the Public
Meeting. Every reasonable effort will be made to accommodate these needs.
The environmental review, consultation, and other actions required by applicable Federal environmental laws
for this project are being, or have been, carried-out by TxDOT pursuant to 23 U.S.C. 327 and a Memorandum of
Understanding dated December 16, 2014, and executed by the Federal Highway Administration and TxDOT.

INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
To provide background information on the City’s street milling efforts in advance of a milling
maintenance contract planned for City Council consideration on May 22, 2018.
BACKGROUND:
Milling is an integral part of the construction cycle of any road. It is the controlled removal of
asphalt or concrete pavement to a desired depth. Milling can solve road deterioration problems
like ruts and unstable asphalt, poor skid resistance, bonding quality, poor pavement profile and
over-asphalted streets. Milling can be used to remove maintenance material and surface flaws to
prepare the surface for an overlay. It can also roughen or texture concrete pavement to restore or
improve friction to the surface that has become smooth over time. The City of Denton maintains a
total of 1331 lane miles (949 are made of asphalt and 382 of concrete).
DISCUSSION:
The milling process is used in both the reconstruction of road CIP projects and preventive
maintenance programs here in Denton. During a reconstruction project, the entire road surface will
be milled off in one pass leaving the subgrade below. The millings can then be recycled back into
the new road that will be reconstructed.
With the preventative maintenance program, only the top few inches of the roadway is milled off.
This allows crews to replace (overlay) only the worn surface with a new asphalt surface. This
increases the Pavement Condition Index and allows the road for it to reach its full life span of 30+
years. If the road is left untreated, the normal life expectancy is roughly 12 years.
The City of Denton uses a 100-point scale for their Pavement Condition Index (PCI). The
Pavement Condition Index combines surface distress (such as rutting, cracking, potholes, punch
outs, and patches) and ride quality into a single index that ranges from 1 (worst condition) to 100
(best condition). The City of Denton’s goal is to raise the average Pavement Condition Index (PCI)
from an average of 65 to a 70 by 2025.
The following steps are used on an annual basis to determine which streets receive the milling
process:
1. Streets are selected for Mill and Overlay (maintenance) by first using the Pavement
Condition Index to identify the streets that are in the 75 - 60 range.
2. Streets scored within the 75-60 range are then visually inspected by City crews to confirm
the scoring.
3. The confirmed list is compared to projects planned in CIP, Water, Wastewater, and
Drainage. This determines if any of the roads have other planned maintenance and
replacement of infrastructure.
Date: May 4, 2018 Report No. 2018-048
4. Roads that are not requiring maintenance or that are already planned for other infrastructure
work are removed from consideration and the remaining streets is the final list.
To maintain productivity levels in the street preventative maintenance program, the City’s milling
program is conducted by City crews and by an outside contractor. City crews are able to handle
smaller milling jobs with City-owned equipment and larger milling work is provided by a
contractor. Staff believes this is a good complement of resources as it allow more roads to be
maintained simultaneously.
On May 22, 2018, staff plans to bring forward a one year (with three (3) additional one (1) year
extensions) milling maintenance contract in an amount not to exceed $2,175,166. Currently the
City of Denton Streets Department has identified 27 streets, totaling 18 lane miles of roadway,
which will be completed for year one of this contract.
CONCLUSION:
In summary, it is the opinion of staff that the milling of streets is a beneficial component of the
City’s street maintenance program.
The City Council will be considering a one year (with three (3) additional one (1) year extensions)
milling maintenance contract at its May 22, 2018 meeting for an amount not to exceed $2,175,166.
If the City Council approves the contract it allows the City of Denton Streets Department to
proactively maintain the City’s streets and work towards raising our overall Pavement Condition
Index to better serve our citizens.

INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
To provide background on the City’s Micro Surfacing program for asphalt streets in advance of a
micro seal maintenance contract planned for City Council consideration on May 22, 2018.
BACKGROUND:
Micro sealing is a type of preventative maintenance that involves applying a thin protective coating
of asphalt emulsion blended with finely crushed stone. This application allows for better traction
to renew the road surface and seal minor cracks to the surface of a street that is still in good
condition. Due to a short application and cure time, about one hour, micro sealing lessens the
impact to our citizens by minimizing lane closure times.
The City of Denton maintains a total of 1,331 lane miles (949 are made of asphalt and 382 of
concrete). Utilizing this program is an appropriate means to prolong the life expectancy of the road
and provide the driver with a safer and smoother ride.
DISCUSSION:
Similar to changing oil in a car, Micro Seal is a cost effective way to maintain an asphalt street’s
good condition before too much damage occurs due to normal wear and tear to the street’s surface.
Micro sealing can extend the life of asphalt pavements another 7-10 years and will increase the
Pavement Condition Index of the street (see attached chart).
The City of Denton uses a 100-point scale for their Pavement Condition Index (PCI). The
Pavement Condition Index combines surface distress (such as rutting, cracking, potholes, punch
outs, and patches) and ride quality into a single index that ranges from 1 (worst condition) to 100
(best condition). This increases the Pavement Condition Index and allows the road for it to reach
its full life span of 30+ years. If the road is left untreated, the normal life expectancy is roughly
12 years.
The following steps are used on an annual basis to determine which streets receive the micro
sealing application:
1. Streets are selected for Micro Sealing by first using the Pavement Condition Index to
identify the streets that are in the 75+ range.
2. Streets scored 75+ are then visually inspected by City crews to confirm the scoring.
3. The confirmed list is compared to projects planned in CIP, Water, Wastewater, and
Drainage. This determines if any of the roads have other planned maintenance and
replacement of infrastructure.
4. Roads not requiring maintenance or are already planned for other infrastructure work are
removed from the list and the remaining streets is the final list.
Date: May 4, 2018 Report No. 2018-049
Micro Sealing is 100% contract work. The City does not have the specialized equipment required
for this process.
On May 22, 2018, staff plans to bring forward a one year (with three (3) additional one (1) year
extensions) micro seal maintenance contract in an amount not to exceed $2,500,000. Currently
City of Denton Streets Department has identified 71 streets, totaling 57.9 lane miles of roadway,
roughly $800,000 which will be completed for year 1 of this contract.
CONCLUSION:
In summary, it is staff’s opinion that the micro sealing of asphalt roads is a beneficial component
of the City’s overall maintenance program for the many miles of streets/roads it maintains.
The City Council will be considering a one year (with three (3) additional one (1) year extensions)
micro seal maintenance contract at its May 22, 2018 meeting for an amount not to exceed
$2,500,000. If City Council approves the contract it allows the City of Denton Streets Department
to proactively maintain the City’s streets and work towards raising our overall Pavement Condition
Index to better serve our citizens.

INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
Water Storage Tank Draining by the Water Production Division of the City of Denton.
BACKGROUND:
Water storage tanks are used as an integral part of the water supply, transmission and distribution
system network. The most common tanks are either ground or elevated storage tanks (“ESTs”,
often referred to as “water towers”).
Ground storage tanks are used to store treated water at one of the city’s two water treatment
plants prior to pumping the water into the distribution systems. ESTs are located within the
water transmission and distribution system, and are used to store pumped water during low water
demand times of the day for and then supply this stored water during when demands peak later
that day. ESTs also help maintain water pressure within the distribution system and are used to
maintain emergency reserves for unplanned events such as fighting fires, loss of pumping due to
power outages, or major losses of water due to main breaks.
The city currently has two water treatment plants and four ground storage tanks with a total
storage capacity of 12 million gallons. Within the water transmission and distribution system
network, the city has ESTs within the Central Middle Pressure Zone totaling 7 million gallons of
storage capacity (Riney Road, McKenna Park, and Roselawn). The City also has two ESTs that
serve the Northwest Upper Pressure Zone and the Southwest Upper Pressure Zone. These two
tanks (referred to as Northwest the Southwest) add an additional 4 million gallons of elevated
storage to these two service areas. The total storage capacity in all of these tanks combined is 23
million gallons. This compares to the average daily water demand for the city of approximately
21 million gallons per day and the combined maximum water treatment plant capacity of 48
million gallons per day.
DISCUSSION:
On occasion, water storage tanks are drained to perform various maintenance functions
throughout the year. The reasons these tanks may be drained and taken out of service vary and
can include routine inspections, maintenance and repairs, or to address water quality concerns
related to water age, nitrification, or insufficient disinfection concentrations.
The Texas Commission on Environmental Quality (TCEQ) requires all public water systems to
conduct annual inspections of all water storage tanks. This involves exterior visual condition
inspections which are performed by city staff. Utilities also conduct “pull down” inspections on
a less frequent basis to inspect the interior tank coating systems. A typical pull down inspection
requires the tank to be drained, washed out, manned entry with visual inspections, and tank
disinfection prior to refilling. Some water systems may use water tank contractors that deploy
robotic inspection devices, or even underwater divers to inspect the interior of the tank while it is
still in service. While these types of inspection do not require tanks to be drained, the
inspections do require specialized contractors that have the appropriate equipment and expertise.
Date: 5/4/2018 Report No. 2018-050
The City of Denton currently uses Water Department staff to conduct the annual external visual
inspections, and to perform internal inspections of tanks on 3 to 5 year intervals.
Storage tanks may also be drained to conduct more extensive condition assessments of the tank’s
interior coating systems. These inspections are infrequent, and are conducted by tank inspection
and coating system experts. Results are used by Water Production staff to prepare specifications
and bid information for removing and replacing the interior coating system. These activities are
generally conducted every 15 to 20 years. As a part of process, the tank will be drained to
complete recoating work and then drained again in a couple of years to inspect for defects and
facilitate warranty repairs. This sequence can result produce situations where tanks are drained
on multiple occasions (inspection, recoating, re-inspection, and warranty repairs if needed).
In addition to regulatory inspections and interior coating maintenance tasks, there can be
situations where water storage tanks are drained for water age and water quality reasons. This
may be done to meet regulatory compliance requirements or to simply ensure water customers
have the highest quality and safest drinking water possible. The majority of these situations are
associated with longer water age and higher water temperatures. Issues can include nitrification,
loss of disinfection residual and, if left unmanaged, bacterial regrowth. There are many methods
to manage these potential water quality concerns and the simplest and most effective method is
to operate pumping systems to keep water moving into and out of water storage tanks on a daily
basis. To accomplish this, water system operators at the treatment plants have standard operating
protocols for finished water pumping cycles that include maximizing water circulation into and
out of the tanks. Tank design features such as mechanical mixers within the tank and having
separate inlets and outlets for the tank can also be used. Disinfection residual loss due to water
age can be resolved by using disinfection boosting facilities at the storage tank to manage
disinfection residual levels. Over the years, the City of Denton has installed some of these
features in their newer facilities has retrofitted many of the older facilities. These actions have
greatly reduced the need to drain tanks or take tanks out of service for managing water quality
reasons.
Over the past two years, the Water Production Division staff has drained water storage tanks on
10 occasions. This included three events related to tank coatings and regulatory inspections, two
events related to installation of tank mixers or tank disinfection reboost systems, and five events
related to water quality maintenance. The five water quality maintenance events occurred
within the Northwest, McKenna Park, and Southwest tanks. The Northwest EST and the
Southwest EST have been more prone to these types of problems since water in these tanks has
already been stored and pumped out of the Central Pressure Planes into the Upper Pressures
Planes. Water quality events typically occur in late summer and early fall when water
temperatures are elevated but water system demand can quickly drop, leading to increasing water
age within the system. To address these concerns, staff has recently installed a disinfection
reboost system for the Southwest EST and plans to install a similar system at the Northwest EST
in the near future.
Date: 5/4/2018 Report No. 2018-050
CONCLUSION:
There are multiple reasons why a water storage tank may need to be drained. Even though
draining of a tank represents a large volume of water, the net loss of water from these activities
represents approximately 0.2% of the total water pumped into the system each year. Staff has
implemented various strategies to minimize this loss of water and continues to explore new
methods to minimize operational water losses.

INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT: Proposed revisions to Community Development Advisory Committee (CDAC) and
Human Services Advisory Committee (HSAC) recommendations.
EXECUTIVE SUMMARY: Both the CDAC and the HSAC presented their recommendations
to City Council on Tuesday, May 1st. On that date, staff also received notice of the City’s
Community Development Block Grant (CDBG) and Home Investment Partnerships Program
(HOME) funding allocation amounts. CDBG funding had increased by $75,756 and HOME by
$127,678. As a result of these increases in funding, Community Development staff developed
some preliminary suggestions regarding the revisions to the CDAC’s and HSAC’s
recommendations.
BACKGROUND: Both the CDAC and HSAC developed their funding recommendations after
staff had completed a process that included advertising the availability of funding, providing
application training and allowing each requesting entity to present their request to the appropriate
committee. The entire process spans a three month period after which, the recommendations are
presented to City Council for approval.
The application timeframe is based on the HUD requirement that the Action Plan, including
information on all future projects/programs to be funded through CDBG and HOME must be
submitted at least 45 days before the start of the City’s program year. Denton’s program year for
CDBG and HOME is August 1st.
DISCUSSION:
FY2018 Funding Allocation Increases
Based upon the HUD allocations provided on Tuesday, CDAC received an additional $59,756 in
CDBG funds and $127,678 in HOME. CDAC recommendations were revised by staff to include
the following:
Fully fund the McKinney Street Sidewalk project at $125,000, an increase of $44,130
from the initial recommendation;
Provide an additional $6,874 to support the rental rehabilitation program carried out by
the Denton Affordable Housing Corporation (DAHC). This is in compliance with the
HOME regulations which state that 15% of a participating jurisdiction’s HOME funds
must support a “Community Housing Development Organization (CHDO). DAHC is a
certified CHDO that serves the Denton area;
Increase the City’s Home Improvement Program budget by $120,804. Total amount
allocated to the program is $475,886.
Increase the City’s Minor Repair Program budget by $15,626. Total amount allocated to
the program is $90,626.
Date: May 4, 2018 Report No. 2018-051
HSAC received an additional $16,000 in CDBG funding. HSAC had already voted to allow staff
to allocate any funding which was 5% or less than their recommendation amounts. The
following are the revised allocation recommendations:
$4,500 SPAN /Meals on Wheels (SPAN) - This moves $4,500 of SPAN’s recommended
General Funds (GF) to CDBG dollars fully fund SPAN in CDBG funds only. The $4,500
will be made available in GF recommendations. There is no change in the overall
recommended allocation to SPAN;
$5,000 Denton County Friends of the Family (DCFOF) - Increase is based on HSAC stated
preference to fully fund the DCFOF request first if additional funds were available.
DCFOF’s total request: $35,000. Increases the recommended allocation from $30,000 to
$35,000;
$3,250 Denton City County Day School (DCCDS) - Total request was $53,058. Increases
the recommended allocation $37,000 to $40,250
$3,250 The Salvation Army- Denton (TSA) - TSA’s total request: $35,000. Increases the
recommended allocation from $20,000 to $23,250
Minor Repair Program
During the City Council work session on May 1, 2018, Council Member Gregory Dalton
requested an expenditure breakdown of the Minor Repair Program (MRP). Below is the
expenditure history for the Minor Repair Program:
Program Year Total
Expenditures
2014/15 PY Expenditures $171,522.86
2015/16 PY Expenditures $176,896.61
2016/17 PY Expenditures $99,831.42
2017/18 PY Proposed Expenditures – PY ends 7/31/18 $138,234.72
According to the MRP application an estimated $115,729 in 2017/18 CDBG funds will be
available at the beginning of the 2018/19 program year. The additional funding will be needed
since the maximum assistance will be increasing from $5,000 to $10,000 due to higher
construction costs.
Proposed Funding
2018/19 PY
MRP Prior Year Funding Available for the 2018/19 PY $115,729
MRP 2018/19 Recommendation $90,626
Total Funding Available for the 2018/19 PY $206,355
Thomas and Wayne Street Water & Sewer Projects
The City Leadership Team also indicated that the Thomas and Wayne Streets water and sewer
projects could be completed through other funding sources. This would allow the $217,923
Date: May 4, 2018 Report No. 2018-051
originally recommended for those projects to be reallocated to other projects or programs. A
meeting with the CDAC will be set-up to discuss reallocating these funds.
Mayor Chris Watts also requested additional information on the income breakdown for the
census tracts related to the Thomas and Wayne Streets water and sewer infrastructure program.
Since the two projects will be funded with other sources the income breakdown was not provided
at this time.
CONCLUSION:
Community Development staff has informed the Human Services Advisory Committee of the
suggested revisions to their recommendations and there was agreement that this would be the
most effective way to use the additional funds.
Staff is also setting up a meeting with the Community Development Advisory Committee to
discuss the reallocation of the additional funding based on the final allocation information from
the U.S. Department of Housing & Urban Development. They will also be asked to discuss the
allocation of the Thomas and Wayne Streets water and sewer project funding.
Staff will revise the 2018 Action Plan as indicated above. Funds that are not allocated to specific
projects and/or programs will be set up in the Plan as “unprogrammed” and the use of these
funds will be determined after submission of the Plan. The Plan will be considered by City
Council on June 5 in order to meet the HUD submission deadline of June 15, 2018. All
“unprogrammed” funds will be allocated to specific projects and/or programs by November 1,
2018. Prior to this date the proposed use of any “unprogrammed” funds will be reviewed by the
CDAC, presented to City Council, and the required 30-day public comment period completed
before the Action Plan is amended and the project and/or program is initiated.

INFORMAL STAFF REPORT
TO MAYOR AND CITY COUNCIL
SUBJECT:
Denton Energy Center(DEC) Market Operations
EXECUTIVE SUMMARY:
The overall fiscal objective for DME is to maximize the financial value of the Denton
Energy Center.
This means that DME's energy schedulers will only offer the DEC to ERCOT at a price which
will recover all estimated fuel and variable costs. Possible exceptions to this pricing policy are
when the DEC must run for environmental and O&M tests, compliance with possible ERCOT
emergency declarations and/or other regulatory mandates, and if needed to provide local
transmission system reliability and support. (Actual exceptions are expected to be infrequent and
limited in scope.)
Attached is a high level summary of ERCOT Generating Unit Scheduling Protocols which
documents how ERCOT determines what generating units to run to meet its grid reliability
mandate.

ERCOT Generating Unit Scheduling Protocols
Protocols are rules under which the grid operator(ERCOT) and all other entities operating
electric networks or generating units must follow.
The following bullet points summarize the protocols and procedures that are applicable to every
generating unit and generation owner/operator in ERCOT.
• ERCOT is responsible for grid reliability. They do not control, or have responsibility for,
financial outcomes.
• ERCOT manages and runs a computer simulation model (looking at 5 minute periods) to
determine the most reliable way to service the grid.
• By 10 am each day("Day-Ahead"), every generating facility must provide ERCOT its
generating unit parameters such as operating cost (fuel and consumables etc.) and other
relevant factors (such as min/max unit capability, min/max runtimes, "ramp"rates, etc.)
ERCOT can initiate an inquiry if it believes the reported unit costs are not reasonable.
• At approximately 1 pm, ERCOT notifies each unit owner/operator of the results of their
simulation study which includes the obligation of generating units to run the next day.
• In"Real-Time", ERCOT makes adjustments to plant schedules as they deem necessary to
address changes occurring in real time for events such as unit trips, transmission line
outages, load changes, etc.
• In addition, generation owners/operators can modify their unit parameters to reflect
changes in their situation with two hour notice to ERCOT.
• ERCOT sends each generating unit a"Base Point" signal directing the unit
owner/operator to operate their plant at this Base Point (i.e. MW output level).
• Base Point signals are sent by ERCOT to generators when the price at a generating
plant's node (connection point to the grid) is at or above a unit's offer price submitted by
the owner/operator.
• Generating units must respond to the Base Point levels sent by ERCOT or face penalties.
• Nodal prices are set by ERCOT based on their grid optimization in order to meet their
objective of keeping grid frequency at 60 HZ.
In summary, ERCOT will determine what generating units are needed during any period of time
to satisfy ERCOT's reliability objective of maintaining the grid at 60 HZ. The AGC system
(automatic generator controls) of generating units will respond to the digital Base Point signals
sent by ERCOT in Real-Time. Owner/operators submit their operating cost and other relevant
information to ERCOT on a daily basis so the grid operator can ensure that units are not operated
at a loss.
