Streets History
The number of street miles maintained has
increased while the number of Streets employees
has dropped. The number of centerline miles per
employee equates to 11.88 the number of lane
miles per employee equates to 55.98.

Resurfacing Prioritization

• Candidate overlay streets are evaluated based on
  the following criteria
• Structural deficiency
• Ride quality
• Vehicle count/repetitive loading
• Age of street
• Coordination Effort between In-house and PPRTA
• Resurfacing list finalized
• The list is initialized right around September of
  each year and is finalized by the end of the year

10
Drainage Maintenance

• The Division, with SWENT personnel, is
  responsible for maintaining the Citys drainage
  infrastructure consisting of
• Open Drainage
• Closed Drainage
• Routine Drainage Maintenance
• Restoration
• Rehabilitation/Reconstruction

District Maintenance
The City of Colorado Springs, Street Division
Maintenance Districts primary functions includes
the maintenance of between 600 to 750 centerline
miles. The main activities performed are as
follows

• Pothole Patching
• Dust Abatement
• Calcium Chloride
• Sweeping
• Minor Restoration
• Grading

14
INSPECTION STAFF

• Field inspections
• Specification compliance
• Resurfacing and Concrete
• Safety
• Stormwater Enterprise
• PPRTA

15
Storm Control
Sanding/Plowing
Summer Storm- flooding
16
Snow and Ice Control

• Level One Storms
• 69 employees per shift 63 route drivers, 4
  Supervisors, 1 Operations Manager, 1
  Communications Dispatcher
• 5-6 hours to cover priority routes throughout the
  city

• Level Two Storms
• Blizzard conditions
• A large defined loop through the
• city is cleared first to provide
• mobility for emergency vehicles.

17
Summer Storm Maintenance

• As soon as the winter storms subside, our efforts
  are redirected towards summer storm control.
• Every summer we remove hundreds of tons debris
  caused by major rain storms common to the front
  range.

18
Recycling Center

• Currently more than 80 of all materials recycled
  come from sweeping, leaf removal, and anti-skid
  from snow removal. These materials are processed
  and returned as useful bi-products for bank
  stabilization, and area/channel beautification.

19
Technical Support

• Automated Vehicle Location (AVL)
• Road Weather Information System (RWIS)
• Pavement Management Application (PMA)
• Work Management System

20
Automatic Vehicle Location
This system provides information on vehicle
location, and roadways being serviced by
snowplows or street sweepers. As a vehicle
passes over its route, position data is
communicated to a control center and serviced
areas are highlighted on an electronic map.
Actual streets swept
21
Automatic Vehicle Location

• System originally developed for Transit and CSFD
  with Congestion Mitigation and Air Quality (CMAQ)
  grant funding
• System then adapted for the Public Works, Street
  Division to assist with the management of fleet
• Currently have or will have 91 units equipped
  w/AVL (focus on Snow Ice and Sweeping
  equipment)
• Capabilities/Benefits
• Near real time vehicle location data
• Historical route tracing
• Operational picture for Supervisors
• Due to hilly nature of Colorado Springs, multiple
  radio towers are needed to provide coverage to
  the whole city (currently _at_ 37 towers)
• Average cost per AVL unit - 2,000
• Budget concerns/issues

Road Weather Information System
The Road Weather Information System (RWIS) allows
real time monitoring of road and weather
conditions. The system consists of pavement
sensing equipment (pucks) placed in the road
surface. When potentially hazardous conditions
exists, the system provides notification via,
e-mail, cell phone or pagers.
24
Road Weather Information System

• The FP2000 sensor can measure
• Surface Temperature
• Wet/Dry Surface Status
• of Chemical
• of Ice
• Depth of Solution
• Type FP2000 surface sensors have three separate
  circuits to record surface temperature, wet or
  dry status and chemicals.
• These circuits, along with air temperature,
  relative humidity and precipitation, combine to
  form a Status at the user display.
• Performance Not degraded by climatic conditions,
  traffic impacts, snow removal equipment or
  deicing chemicals

25
Road Weather Information System

• Each weather station calculates, stores and
  transmits current information from surface,
  subsurface and atmospheric sensors.
• Atmospheric sensors provide visibility, dew
  point, relative humidity, wind speed and
  direction, air temperature, amount and type of
  precipitation (snow, rain, sleet, etc.) specific
  to the location. This is useful in dispatching
  crews to the areas of town where the worst
  weather is occurring.
• Road sensors detect the pavement temperature,
  subsurface temperature, surface condition(dry,
  wet, icy), amount of deicing chemical on the
  roadway and freezing point of the pavement
  surface. This information is pertinent to
  summer and winter operations including
  resurfacing and storm control. The pavement
  conditions can vary significantly from the
  atmospheric conditions generally provided in
  weather forecasts.

Pavement Management Application

• Pavement Management Application is a systematic
  and consistent method of evaluating and rating
  streets. This system will also assist in
  planning and coordinating our resurfacing
  program.

28
Pavement Management Application

• The main goal of the Pavement Management
  Application (PMA) is to provide a systematic
  process to assist in the following areas
• Justification of Capital Improvement Project
  (CIP) budget requests
• Selection of cost-effective strategies/actions to
  improve efficiency and safety of the pavement
  network
• Comprehensive inventory data base of all
  residential/arterial/collector streets
• Objective evaluation/assessment of short/long
  term condition of the network
• Objectively determine maintenance/rehabilitation
  programs
• Models to assess/predict current and future
  pavement performance
• Protection of investments made in pavement
  infrastructure

29
PMA Roadway Assessment Ratings
30
Pavement Management Application

• Concerns/Issues
• Annual funding to
• provide for contractual
• assessment of 1/3 of all
• roadways or
• Up front expenditure to purchase the necessary
  vehicle and equipment to allow Street Division
  staff (Inspectors) to conduct roadway assessments
• Software upgrades/updates per vendor

31
Work Management System

• TRAKS Time Record Accounting
  Keeper System
• Daily Time Record Keeping
• Tracks labor, equipment and material
• Daily/weekly/activity reporting ability
• Auditing capabilities
• Work Maintenance Management System
• New System assessment being conducted
• User friendly/not manual intensive
• Very Audit friendly
• Audit Activities Past/Future
