Transportation
REQUESTING DEPARTMENT / PRESENTERS

Jacob Lindsey, Planning and Development Services Director
Edward Stafford, Development Review Manager
Transportation and Mobility
Gerrit Slatter, Principal Transportation Projects Engineer
Noreen Walsh, Project Manager
OBJECTIVE
Define the steps for Planning Board consideration of this request:
1. Receive this written update on the scope of work for transportation updates
to the Design and Construction Standards
SUMMARY
The purpose of this item is to provide a written update to the Planning Board about the scope of
the next phase of the city’s Design and Construction Standards (DCS) and Boulder Revised Code
(BRC) updates related to Transportation. The phase 2 updates will further align the standards
with adopted policy and technical documents related to transportation infrastructure so private
and public construction projects are designed and constructed using industry standards and
guidelines for safety, mobility, sustainability and/or quality. The updates selected for 2021
recognize limited city resources available to complete this work, and additional updates beyond
2021 have been identified for inclusion in future work plans.
STAFF RECOMMENDATION:
No action is requested at this time. If the Planning Board has questions or comments they should
be sent to Edward Stafford, Development Review Manager at StaffordE@bouldercolorado.gov.
Suggested Motion Language:
No action is being requested of the Planning Board at this time.
PUBLIC FEEDBACK
A verbal update on the DCS project was provide to the Transportation Advisor Board (TAB) at
their November meeting. TAB expressed support for the work and had questions about how the
DCS coordinates with parking minimums and how the city’s pedestrian crossing treatment
guidelines update project will factor into this project. This project will not address parking
minimums as that is a land use regulation item that is included in future work on the AMPS
project.
BACKGROUND
The Design and Construction Standards is used to prescribe minimum standards to be used in the
design and construction of public infrastructure located in public right-of-way and easements
with in the city of Boulder, as well as private transportation and utility improvements that
connect or impact public infrastructure. The DCS is enacted through the BRC and changes are
adopted by City Council with recommendations from appropriate boards, such as TAB, Water
Resources Advisory Board, and Planning Board.
In 2019 and 2020 two updates to the DCS were completed and ultimately adopted by City
Council. The first update was to the utilities sections of the document and include changes to
meet current stormwater management regulations and updates to reflect best practices and
current operations of the city’s utilities systems. The second update was related to transportation
standards and was intended to be the first of several phases of updates for transportation. This
first set of transportation updates included changes to implement current best engineering design,
construction and maintenance processes, new and improved materials and technical details, and
continuing efforts to align the standards with other adopted policy documents, such as the
Transportation Master Plan (TMP) and Boulder Valley Comprehensive Plan.
Over the past several years there have been many transportation related changes proposed for
DCS updating in response to community concerns regarding the current transportation related
design and construction standards. Additionally, the Transportation Master Plan Update in
September 2019, completion of the Transportation Landscape Maintenance Plan in 2020 and
other transportation staff work has highlighted additional items to be updated in the DCS. The
proposed changes included in this memo address clarifications, current best practices, and
adopted master plan policy direction and represent the next part of the phased updates to these
standards.
ANALYSIS
The purpose of the phase 2 update the city’s Design and Construction Standards transportation
related sections is to further align the standards with adopted policy and technical documents so
private and public construction projects are designed and constructed using industry standards
and guidelines for safety, mobility, sustainability and/or quality.
Due to the impacts of COVID-19 on sales tax revenue, the staff and funding resources for this
project have been reduced and this project has been prioritized along with the rest of the
Transportation and Mobility and Planning and Development Services departments’ work plans.
The timeline has been extended so that all of the identified updates occur over the course of
several years. The 2021 updates will be completed with the use of consultants which addresses
staff capacity issues and provides subject matter expertise. In 2021, the new funds available total
$50,000 along with some limited funding from a previously arranged contract. The sections
proposed for 2020 were selected for both their priority of importance and the staff and funding
resources being available to complete the work. Since the consultant selection process has not
been conducted and the actual costs are unknown, it is possible that some section updates will
need to occur in 2022. The 2022 budget will plan to allocate additional funding for this project.
DCS and BRC Section to be updated in 2021:
• 2.07 Street Geometric Design – changes to standards related to radius of intersections,
curb returns, horizontal curves, design speed, turning radius, for improved safety for
bicyclists and pedestrians
• Chapter 3, 10, 11 and check 6.6 and 9.3 Landscaping – changes to tree buffer, irrigation
and list of recommended plantings to use to reflect Transportation and Mobility
department’s Landscape Maintenance Plan and other Parks and Recreation work efforts.
• BRC – Sight Triangles – changes include new sight triangle for public multi-use paths
where they intersect with a driveway or alley and a design standard where existing
buildings do not allow for sight triangle(s) to be achieved.
• Chap 11 Tech Drawings - revise existing technical drawings, as needed, in the DCS to
reflect current design practice.
• 1.03 Engineering Reports – ensuring that the right content in the reports that need to be
submitted as part of development e.g. pavement design reports, geotechnical analysis
• Chap 8, Pavement Cuts Restoration Standards – ensuring that the work done by others
meets industry standards
The following items have been identified for future updates in 2022 and beyond:
• 2.02 and 2.03 Traffic Study and Traffic Study Formats
• 2.04 Site Access
• 2.08 Sidewalks
• 2.09 Residential Street Design
• 2.12 Street Lighting Standards
• 8.02 Traffic Signal Standards
• 8.04 Work Zone Traffic Control
• Bridge and Retaining Wall Standards
• Emergency Access Standards
• Alley design and functionality standards
NEXT STEPS
Staff is working to finalize the scope of work for this phase of the update and will be posting a
Request for Proposal prior to the end of the year. Work on the updates will commence in early
2021, with the updates ultimately being presented to the TAB and the Planning Board for
recommendations and City Council for potential adoption later in 2021.
