1. EXECUTIVE SUMMARY

The RTD Sustainability Program reflects the agency’s mission by focusing on Responsible,

Thoughtful, and Dependable solutions.

The Regional Transportation District (RTD) Sustainability Program is an economic, social and

environmental triple-bottom line (TBL) framework that fulfills the RTD mission of providing

safe, clean, reliable, courteous, accessible and cost-effective service. The TBL focuses on

economically responsible, environmentally thoughtful and socially dependable solutions for

present needs without sacrificing the future. RTD has a service area of 2,326 square miles and

serves a population of 2.7 million, carrying over 325,000 passengers daily. This is RTD’s update

for the year 2011 on its Sustainability Program.

RTD and Sustainability

In 2006, at the outset of the FasTracks program, the RTD Board of Directors adopted a

Sustainability Policy with accompanying Sustainability Guidelines. The policy’s goal is to

incorporate sustainability in all of RTD’s activities.

In 2011, RTD moved more passengers and reduced consumption. Despite the rising cost of

energy and water, operating costs remained the same as the previous year.

This 2011 Sustainability Report update documents the macro level changes to the state of the

system – namely the services delivered to the community, and the corresponding resources

used to deliver those services. The most significant level of change in the future is expected as

new rail lines become operational and as bus service modifies.

In 2011, the RTD system provided a community service increase while reducing its

environmental footprint. Unlinked Passenger Trips increased 1.6 percent and passenger miles

increased 6.5 percent over the previous year as reported to National Transit Database (NTD) by

RTD. Greenhouse Gas Emissions were calculated 2.69 percent lower than 2010.

The 2011 RTD sustainability highlights include the following:

Denver Union Station (DUS)

DUS is on track to be LEED-Silver Certified.

DUS completed the LEED design phase submittal review with all credits accepted.

Energy efficiency measures include a performance improvement of 25.7 percent over

the baseline defined by ASHRAE; this includes improved thermal envelope, high-


efficiency glazing, reduced interior lighting power density and high-efficiency HVAC

equipment.

Earned LEED credits include Brownfield Redevelopment and Bicycle Storage/ Changing

Rooms.

West Rail Line

Utilized 32 biodiesel capable vehicles and 21 highly efficient (SUVs) construction vehicles

on the project. All construction equipment met or exceeded State of Colorado Air

Quality Emission Standards.

Recycled 39,000 tons of asphalt and concrete, of which we have reused 54 percent,

21,000 tons, onsite for stabilization under new roadways.

Re-vegetated close to 200 acres of off-guideway corridor with drought tolerant, non-

irrigated native seed.

EAGLE (East and Gold Rail Lines)

Sustainability Plan in initial draft stages.

Denver Transit Partners (DTP) assigned a senior level manager as the Sustainability

Coordinator for the project.

Contributed $145,000 to the Workforce Initiative Now (WIN) Program and hired

qualified WIN candidates for the project.

The design and construction phases of the project have surpassed its DBE/SBE goal

The design and construction for the Commuter Rail Maintenance Facility (CRMF) is on

track for LEED-Silver Certification.

The CRMF power density estimate is 38 percent below the base line.

Remediated 21,586 square yards of contaminated soils.

Adopted a Dust Mitigation and Particulate Mitigation Plan; as required by law.

The CRMF is on track to divert 75 percent of all construction and demolition waste

including concrete, asphalt and rail scrap.

Saved 264 tons of surplus rails from the West Line for reuse in the Eagle P3 project

Concrete ties and rails are manufactured locally.

Rail cars will be equipped with regenerative braking.

Northwest Rail Line/US36 BRT

Design of bus slip ramps will reduce commuting times and minimize conflicts with traffic.

Bus Rapid Transit (BRT) stops with bicycle traffic will be equipped with bicycle racks and

lockers.


North Metro Rail Line/I-225 Line

As both projects get started, a sustainability plan is being developed and coordinated by

the consultant.

Southeast Rail Extension

The project is considering design alternatives for a photovoltaic array to satisfy site

illumination needs.

Lighting criteria will optimize illumination levels and reduce energy consumption.

Each of the stations allows for potential TOD parcels.

Rail Operations

Averting the need to expand cooling systems, SCADA (Supervisory Control and Data

Acquisition) upgraded computer systems reducing energy costs by a third after retiring

inefficient computer servers.

LRV Maintenance shortened the time the HVAC stays on after the operator turns the

vehicle off.

Interior lights are turned off during the day on all parked LRVs.

To improve performance, maximum draw on LRVs have been reduced from 1200amps

to 900amps.

Base System Operations

Platte Drivers End Remodel - Added a stairway to the roof for convenience and safety.

FM personnel had previously been walking up and down a 45° slope and climbing over a

roof parapet to reach the roof for maintenance.

Platte Engine Wash Hoist Replacement: Removed a non-functioning floor mounted

platform hoist in the engine wash bay. The hoist is being replaced with new more

efficient mobile column hoists which will make this service bay functional again.

Platte North Lot Asphalt Repairs: Repaired cracks up to 3” wide and resurfaced the

driver’s parking lot to eliminate tripping hazards.

Facilities Concrete Pavement Repairs: Removed and replaced broken concrete

pavement at District Shops, Platte and East Metro to eliminate tripping hazards for

personnel and damage to vehicles.

Boulder Mechanical Upgrade: this project replaced and upgraded 30 year old HVAC

equipment and control systems to make the Bus Operations Building more comfortable

and energy efficient.

District Shops Fire Protection Upgrade: the project brought the building up to current

Denver Fire Department requirements as well as adding additional fire protection to our


records storage building. The entire District Shops and associated out buildings fire

alarm system was reviewed and updated.

RTD Engineering

In preparation for the future Pine Junction p-n-R construction, RTD transplanted fifteen

(15) large native ponderosa pines outside the future construction zone. The trees will

be incorporated into the future p-n-R landscape and provide a vegetative buffer for the

property.

Twenty four (24) pines were transplanted from the future Pine Junction p-n-R to Twin

Forks p-n-R, reducing pavement reflectivity and heat island effect while elevating the

Twin Forks p-n-R aesthetics.

Next Steps:

Section 4 of this report includes descriptions of next steps to move the RTD Sustainability

Program forward

The RTD Sustainability Policy and Guidelines, established in 2006, shall be reviewed and

recommended to the board for an update.

Coordinate the sustainability program with the RTD Long Range Fiscal Sustainability Task

Force as they investigate long term fiscal opportunities.

RTD staff is considering creation of an RTD Sustainability Coordinator/Manager position.

Renew efforts to establish a Green Procurement Policy.

Continue the ongoing RTD Sustainability Program efforts.

Monitor rising trends connected to sustainability.

Continue to review sustainability metrics to evaluate this sustainability program.

Measure changes in walkability for rail stations to be open April 26, 2013.


2. RTD SUSTAINABILITY PROGRAM

Sustainability is the capacity to give support. For humans, sustainability is the long-term

maintenance of well-being, which has environmental, economic and social components. As

illustrated in Figure 2 below, the RTD Sustainability Program seeks to balance the delivery of

effective public services (external activities) with the implementation of efficient business

activities (internal management practices). This results in an increased quality of life, a smaller

environmental footprint and cost-effective management of resources and materials. With the

endorsement of the United Nations this became the dominant approach to public sector full

cost accounting. In the private sector, this is known as “corporate social responsibility.”

Figure 2 RTD Sustainability Program Concept Chart


3. RTD SUSTAINABILITY CULTURE

RTD’s sustainability program is part of the daily tasks of the agency. The chart below highlights

the fundamental factors which comprise RTD sustainability culture, objectives, and indicators.

RTD uses indicators as a sign or group of statistical values to measure whether the agency’s

activities are within its sustainability culture and whether it meets its sustainability objectives.

RTD’s sustainability indicators provide useful metrics to identify problems before they become

critical, and to spotlight the areas where the links between the environment, economy and

society are weak. The indicators below fall into the three objectives of sustainability outlined by

RTD policy.

Figure 3 RTD Sustainability Culture chart

3.1. QUALITY OF LIFE

Quality of Life is used to evaluate the general well-being of individuals and societies. Quality of

life should not be confused with the concept of standard of living, which is based primarily on

income. Instead, standard indicators of the quality of life include not only wealth and

employment, but also the built environment, physical and mental health, education, recreation,

social belonging and leisure time.


3.1.1. GREATER TRAVEL CHOICES/ACCESSIBILITY

Optimized Transit Service refers to growth and improvements to the transit network, including

new rail and bus routes, increased frequency, directivity, speed, and the facilities that support

those services. Transit service is most efficient when a least number of passenger miles traveled

(PMT) are given by the highest number of boardings. In 2011, Annual Passenger Miles saw a

4.23% increase to 558 Million. There were slight decreases in the Annual Passenger Miles

traveled on the bus and direct response system. The increase came from the LRT system

(Figure 4).

The FasTracks Program consists of nine rail corridors, one bus rapid transit corridor,

redevelopment of Denver Union Station, a new Commuter Rail Maintenance Facility and an

expanded light rail maintenance facility. At completion, the program will add approximately 93

miles of commuter rail, 28 miles of light rail, 18 miles of BRT, park-n-Ride improvements and/or

relocations at existing park-n-Ride lots along US 36.

Balanced Transit Access is the ability for people to approach transit in a convenient way, such

as being within walking distance to origin and destination, or efficient transfers from one mode

of transportation to another. This refers also to the capacity for people with special needs to

get access to special transportation.

Public Involvement engages the community in planning and project development in order to

increase the pool of common knowledge and build trust. Public involvement is based on giving

people the opportunities to debate issues, frame alternative solutions, and affect final decisions

in ways that respect the roles of decision-makers.

Multimodal Opportunities refers to linking the interaction of various modes of transportation

(walking, cycling, automobile, public transit, etc.) with planning and development, and the

connections among such modes so each can fill its optimal role in the overall transport system.

3.1.2. LIVABLE COMMUNITIES

Air Quality: Although air quality, based on EPA’s readings, has improved significantly since the

passage of the Clean Air Act in 1970, there are still many areas of the country where the public

is exposed to unhealthy levels of air pollutants and sensitive ecosystems are damaged by air

pollution. RTD’s role in improving air quality includes curbing greenhouse gas emissions,

particulate matter and ozone producing pollutants.

Water Quality: Water quality is measured by standards set by the EPA relative to health of

ecosystems, safety of human contact and drinking water. RTD complies with all water quality

law and in addition implements measures that reuse water for irrigation purposes and help

prevent the waste of water.

RTD has installed several rain sensors at its facilities and three weather stations to be

used as tools in the optimal allocation of water for irrigation purposes throughout the

District.

The RTD park-n-Ride at US 36 and McCaslin Blvd. is irrigated with reclaimed gray water

supplied by the Town of Superior.


Reduce Congestion: Rail and bus service will slow the increase of congestion and daily VMT

growth. If congestion in the region increases, transit modes, particularly those with dedicated

right-of-way, will likely also see an increase.

Transit-Oriented Development is a mixed use area that is compatible with other uses and is

characterized by convenient access to transit. TOD often incorporates features to encourage

transit ridership. A TOD neighborhood typically has a center with a transit station or stop,

surrounded by relatively high-density development with progressively lower-density

development spreading outward from the center. TODs generally are located within a radius of

one-quarter to one-half mile from a transit stop, as this is considered to be an appropriate

walking distance for pedestrians. RTD’s TOD program has been and will continue to coordinate

with other programs to promote the benefits of sustainability.

Walking is a method of accessibility; more people access transit by walking than by any other

means. Because walking is ecologically stable, promotes health and social connections,

walkability is used as an indicator of sustainability. Transit supports walkable communities at

both ends of the trip, at the origin by promoting residential densities that support pedestrian-

scale neighborhoods and at the destination by promoting easy access to employment, services

and recreation.

WIN: The regional Workforce Initiative Now (WIN) is a collaborative partnership between RTD,

Community College of Denver, Denver Transit Partners (DTP) and the Urban League of

Metropolitan Denver. WIN helps job seekers, companies, and local communities through the

creation of career opportunities in the transportation and construction industries.

DBE/SBE/MBE Participation on Projects: FTA recipients receiving planning, capital and/or

operating assistance who will award prime contracts exceeding $250,000 in FTA funds in a

Federal fiscal year are required to have a Disadvantaged Business Enterprise (DBE) Program

that complies with the requirements of federal regulations codified at 49 CFR Part 26. As an

applicable recipient, RTD is continuing to implement a DBE Program consistent with federal

requirements. Recently, RTD not only reorganized its Small Business Department (re-naming it

the Civil Rights Department) but revised its DBE Plan and implementing Program to continue to

comply with the federal DBE Program requirements. RTD has consistently established DBE

participation goals; in the process, members are notified of the program requirements, given

comprehensive compliance monitoring, provided with technical assistance and supportive

services, and provided with training on the program requirements.


Transit Watch refers to passengers being alert and aware; passengers are encouraged to report

suspicious activity. The CERT program is a safety and security partnership between RTD and its

passengers in which RTD asks its users to receive orientation to and make a commitment to be

an alert, informed, prepared and involved passenger.

3.2. ENVIRONMENTAL SUSTAINABILITY

Environmental Footprint: The environmental footprint is a measure of human demand on the

Earth's ecosystems. It is a standardized measure of demand for natural capital that may be

contrasted with the planet's ecological capacity to regenerate.

The following is a tabulation of significant environmental impacts of the RTD system.

Reduce Energy Use: The total energy used by the RTD system showed a decrease of 3.56%

in the year 2011. For this calculation all energy units were converted to kilowatt-hour

assuming that one kilowatt-hour is equal to 3,413 BTU. Average Mean temperatures were

slightly cooler in 2011 than in 2010. Of all the forms of energy used, the percentage of

electricity used increased, while the percentage of diesel use decreased.

Reduce Greenhouse Gas Emissions: Greenhouse Gas Emissions are affected by the

amounts and types of fuels used by the RTD system. Following the decrease in total fuel

use, the calculated Greenhouse Gas Emissions showed a 2.69% decrease from 2010 levels.

4. NEXT STEPS

There are a number of items that need to be considered to continue moving forward with the

Sustainability Program as follows.

RTD Sustainability Policy and Guidelines Update: the current policy was drafted in 2006 and

needs an update to reflect some of the conditions that characterize the District today and state-

of-the-art sustainability measures.

Fiscal Sustainability (RTD Task Force): the Sustainability Program shall coordinate with the Long

Range Fiscal Sustainability Task Force who is looking at the opportunities for operating

efficiencies and revenue enhancements to promote RTD fiscal sustainability in the long term.

RTD Sustainability Coordinator/Manager position: the purpose of this position would be to

manage an agency-wide environmental management system and to foster the sustainability

program. This position would implement management processes and procedures to allow RTD

to analyze, control and reduce the environmental impact of its activities, products and services

and operate with greater efficiency and control. Benefits of implementing an environmental

and sustainability management system may include better accountability and cost reductions in

operations and maintenance. One of the tools commonly used for this purpose is the ISO 14001

standard.

Advancing RTD sustainable policy: Update current standards and create new RTD Standards

improving the state-of-the art to include

Landscape (Xeriscaping)

Solar Photovoltaic Systems

Lighting

Mechanical

Recycling

Fuel Efficiency/Transit Effectiveness

Advancement of Green Procurement Policy: RTD staff should take into account long term

maintenance considerations while specifying products. To start with, RTD may want to study

various approaches to Life Cycle costing methodologies for the bigger purchase categories to

start with. RTD does need to maintain all its infrastructure and vehicles in good working

condition, while operating within a framework of many regulations that govern procurement.

Questions to address include:

1. What constitutes a green product or service?

2. How do we verify we will get the green attributes of products and services we desire?

3. How much of a premium are we willing to pay for desirable environmental attributes?

4. How much of a premium are we willing to pay for lower maintenance costs?


5. How do we incorporate the above considerations into our designs, specifications, and

procurement documents?

Collaboration with other agencies: Increase the collaboration with other agencies and

programs including the Colorado Environmental Leadership Program.
