TO: HONORABLE MAYOR AND BOARD OF DIRECTORS
FROM: BRUCE T. MOORE, CITY MANAGE
SUBJECT: QUESTIONS REGARDING, MASTER STREET PLAN
DATE: APRIL 3, 2015
Vice -Mayor Hines had requested the following responses to the questions
regarding the Master Street Plan, Bicycle Plan and the proposed Complete
Streets Ordinance, and the following:
1.
2.
3
Diagram: Principal Arterial Design Standards Stage 2 (Final) Construction
(from the Master Street Plan, Design Standards Chapter, showing a divided
six (5) -lane street).
"What does this section look like with Class II bike lane? The bike lane
would be striped along the outer lane of both sides of the street so there
would be four (4) lanes for motorized travel (two (2) in each direction) and two
(2) bike lanes.
Will we have adequate long term capacity with just two lanes for
traffic?" The Public Works Department would review the specific street
volumes to determine capacity issues for motorized vehicle needs and, if
needed icir rnutur vehicle needs, the three (3) travel lanes in each direction
would remain and no bike lane would be required. Years hence, future study
by the Public Works Department might show further adjustments are needed,
as with any street corridor, in which case the changes could then be made.
Diagram: Initial Construction of Principal Arterial (from the Master Street Plan,
Design Standards Chapter, showing a divided 4 -lane street).
"What does this section look like with Class II Bike Lane?" The Bike
Lane would be striped along the outer lane. This would result in one (1)
motorized lane in each direction with one (1) bike lane in each direction. The
Public Works Department would review the specific street volumes to
determine capacity issues for motorized vehicle needs and, if needed for
motorized travel, the two (2) travel lanes would remain and no bike lane
would be required.
Section: Principal Arterials with Altemative Design Standards (90 -foot right-of-
way with 5 lanes, one of which is a turn lane)
City of Little Rock, Arkansas
"Some of these streets are shown as Class II Bike Lanes will these
alternate sections have adequate capacity w/ bike lanes marked out in
each direction?" The Public Works Department would review the specific
street volumes to determine capacity issues for motorized vehicle needs and,
if needed for motorized vehicle travel, the two (2) travel lanes with center turn -
lane would remain and no bike lane would be required.
4. Section: Principal Arterials with Alternative Design Standards
"Will the Bike Lanes be safe with the speeds and traffic?" By State Law,
bicyclists have the right to ride their bicycles on public streets. The reason for
a Class II Bike Lane, rather than just allowing bicycles to mix with motorized
vehicles, is to increase safety.
5. Diagram: Minor Arterials Five (5) -Lane Design Standard)
"Where do we place the Class II bike Lanes when we need this section
based on traffic volume?" The Public Works Department would review the
specific street volumes to determine capacity issues for motorized vehicle
needs and, if needed for motor vehicle travel, the two (2) travel lanes with
center turn -lane would remain and no bike lane would be required. Otherwise,
there would be no center lane but four (4) lanes for motorized travel and two
(2) striped bike lanes in the outer lanes.
6. Diagram: Minor Arterial Four (4) -Lane with Median
"Bike Lanes?" The Bike Lane would be striped along the outer lane. The
Public Works Department would review the specific street volumes to
determine capacity issues for motorized vehicle needs and, if needed for
motor vehicle travel, the two (2) travel lanes in each direction would remain
and no bike lane would be required. (This is basically the same situation as in
Question 2 above.)
7. Diagram: Minor Arterial with Bike Lane
"What do we do if we need the center turn -lane for driveway traffic?" If
a left turn -lane is needed for a development at a particular location, then the
same design would be employed as is used at an intersection where traffic
merges together into the right lane to accommodate placement of a turning
lane. (This is basically the same situation as in Question b above.)
8. Diagram: Standard Collector with Bike or Parking Lane
"What does this section look like with Class II Bike Lanes on each
side?" There would no parking on the one side shown in the graphic, unless
the street is a one (1) -way street, in which case both the parking and the bike
lane could be accommodated on the street.
"What do we do if we need a center turn -lane due to traffic volume?"
The Public Works Department would review the specific street volumes on
the street to determine capacity issues. If the study showed a need for a
center lane, there would only be a striped center lane and a travel lane in
each direction and no bike lane would be striped. (This is a similar situation
to the Question 5 above.)
9. Diagrams: Other Collector Design Options (showing five (5) different collector
design options)
"What do these sections look like with Class II Bike Lane on each side?"
Three of the four (4) diagrams note that they are without bike lanes, so no
bike lane would be present on either side for the situations represented by
those three diagrams. As to the one diagram labeled Residential or Minor
Commercial Collector (Special Conditions) w/ Bike or Parking Lane, the bike
lane is shown on the right-hand side. The Public Works Department would
review the specific street volumes, the needs for bicycle travel, and the needs
for parking and determine whether a bike lane or a parking lane would be
placed in the six (6) -foot area of the pavement. Note that this is a rare road
configuration usable only in special circumstances after a request of the
developer.
10. & 11. Section: Minor Arterials with Alternative Design Standards
Subsection: Right-of-way seventy (70) feet with four (4) -lane section, five (5) -
lanes at major intersections with additional right of way
"Same questions adequate capacity w/ 2 bike lanes?" The Public Works
Department would review the specific street volumes to determine capacity
issues for motorized vehicle needs and, if needed for motor vehicle travel, the
two (2) travel lanes would remain and no bike lane would be required. (This is
a similar situation to Question 3 above.)
"Will Bike Lanes be safe w/speed & Traffic?" The reason for a Class II
Bike Lane rather than just allowing bicycles to mix with motorized vehicles, as
they are allowed to do by State Law, is to increase safety. (This is a similar
situation to Question 4 above.)
12. Section: Class /(with Road or without Road) Bike Paths
"What does this mean?" (We assume this question is about the nearby
sentences stating that Class I Paths are to be used when motor vehicle
speeds or volumes are too high for Class 11 bike lanes and where connections
need to be made where no roadways exist, such as following a creek bed.)
The sentences mean that the Public Works Department would review the
specific street volumes and speeds on that particular street and if there were
safety concerns about bicycle travel, a Class I Path separated from traffic
might be recommended. Class I Paths are also recommended where
connectivity is needed to ensure continuity of bicycle travel. The Bicycle Plan
now shows few Class I routes, with several such routes having been
eliminated in the last change to the Bicycle Plan accomplished in 2011.
13. Section: Class 11 Bike Lanes
"Not consistent with cross sections." Staff does not see any
inconsistency.
"Don't we need the turn lane for adequate capacity?" Please see the
answer to Question #6 above, except this answer applies to a commercial
street rather than a collector. Commercial streets and collector streets share
the same design standard.
14. Section: Class 111 Bicycle Routes
"Do we show any Class III where speeds are 30+ MPH or 50% on
capacity?" The bulk of the streets where Class III Bicycle Routes are
designated in the Master Bike Plan are collectors and local streets. Local
street design speed is twenty-five (25) MPH and for collectors is thirty (30)
MPH. As to capacity, as a general rule the City only regularly performs
counts on arterials and intersections. We do not; therefore, have this
information, The Public Works Department will review the speeds and
volumes of specific streets prior to a bike route being marked, however.
15. Section: Construction Standards (Bicycle Chapter)
"Are we going to bring existing Class I Paths up to these Standards? Do
they meet them now?"
As with all sections of the Master Street Plan, over time and as projects are
proposed, the City is working to implement all sections of the plan, whether it
involves a street, sidewalk or bicycle facility. Acquisition of property for Class I
Bike Paths and construction to Class I Bike Path standards will be
accomplished by the City as it has grants or other funding available and as a
priority need arises.
16. Section: Construction Standards (Bicycle Chapter)
"Total width is eighteen (18) feet - do our paths comply?" Class I paths
have various widths depending on whether they are to be one (1) -way or two
(2) -way paths or have pedestrian use as well as bicycle use. The maximum
standard of eighteen (18) feet is only needed where two (2) -way bike and two
(2) -way pedestrian travel is required. Many of the current Class I Bike Paths,
just as many of our city streets, are not currently to full standard.
17. Section: Construction Standards (Bicycle Chapter, footnote stating that if on -
street parking is desired, additional right-of-way and paving will be required,
subject to Traffic Engineering approval.)
"Please explain criteria for decision." As with any street, whether bicycle
travel is or is not involved, if a development wants on -street parking, the
design must be reviewed by the City engineers for each specific location for
safety and traffic movements.
If additional information is needed, please advise.
TO: VICE MAYOR LANCE HINES
FROM: BRUCE T. MOORE, CITY MANAGER
SUBJECT: QUESTIONS REGARDING MASTER STREET PLAN
DATE: MARCH 11, 2015
Per your request, I asked staff to prepare responses to the questions that you submitted regarding
the Master Street Plan, Bicycle Plan and the proposed complete streets ordinance. The questions
presented are about the Master Street Plan and generally fall into a few similar categories. Most
of the questions concern the various cross-section diagrams showing options for various street
types with an even number of lanes or odd number of lanes. Other questions are about how the
City would address alternative design standards. A third group of questions deals with capacity,
marking issues and some questions ask about the design standard for bicycle facilities under
various existing conditions. The questions are responded to individually.
(1) Diagram: Principal Arterial Design Standards Stage 2 (Final) Construction (from the
Master Street Plan, Design Standards Chapter, showing a divided 6 -lane street).
"What does this section look like with Class II bike lane? The bike lane would be striped
along the outer lane of both sides of the street so there would be 4 lanes for motorized travel (2 in
each direction) and 2 bike lanes.
Will we have adequate long term capacity with just two lanes for traffic?" The Public
Works Department would review the specific street volumes to determine capacity issues for
motorized vehicle needs and, if needed for motor vehicle needs, the 3 travel lanes in each
direction would remain and no bike lane would be required. Years hence, future study by the
Public Works Department might show further adjustments are needed, as with any street
corridor, in which case the changes could then be made.
(2) Diagram: Initial Construction of Principal Arterial (from the Master Street Plan, Design
Standards Chapter, showing a divided 4 -lane street).
"What does this section look like with Class II Bike Lane?" The Bike Lane would be striped
along the outer lane. This would result in one motorized lane in each direction with one bike
lane in each direction. The Public Works Department would review the specific street volumes
to determine capacity issues for motorized vehicle needs and, if needed for motorized travel, the
2 travel lanes would remain and no bike lane would be required.
(3) Section: Principal Arterials with Alternative Design Standards (90 -foot right-of-way
with 5 lanes, one of which is a turn lane)
"Some of these streets are shown as Class II Bike Lanes will these alternate sections have
adequate capacity w/ bike lanes marked out in each direction?" The Public Works
Department would review the specific street volumes to determine capacity issues for motorized
vehicle needs and, if needed for motorized vehicle travel, the 2 travel lanes with center turn lane
would remain and no bike lane would be required.
(4) Section: Principal Arterials with Alternative Design Standards
"Will the Bike Lanes be safe with the speeds and traffic?" By state law, bicyclists have the
right to ride their bicycles on public streets. The reason for a Class II Bike Lane, rather than just
allowing bicycles to mix with motorized vehicles, is to increase safety.
(5) Diagram: Minor Arterials (5 -lane design standard)
"Where do we place the Class II bike Lanes when we need this section based on traffic
volume?" The Public Works Department would review the specific street volumes to determine
capacity issues for motorized vehicle needs and, if needed for motor vehicle travel, the 2 travel
lanes with center turn -lane would remain and no bike lane would be required. Otherwise, there
would be no center lane but 4 lanes for motorized travel and 2 striped bike lanes in the outer
lanes.
(6) Diagram: Minor Arterial 4 Lane with Median
"Bike Lanes?" The Bike Lane would be striped along the outer lane. The Public Works
Department would review the specific street volumes to determine capacity issues for motorized
vehicle needs and, if needed for motor vehicle travel, the 2 travel lanes in each direction would
remain and no bike lane would be required. (This is basically the same situation as in Question 2
above.)
Diagram: Minor Arterial with Bike Lane
"What do we do if we need the center turn lane for driveway traffic?" If a left turn lane is
needed for a development at a particular location, then the same design would be employed as is
used at an intersection where traffic merges together into the right lane to accommodate
placement of a turning lane. (This is basically the same situation as in Question 5 above.)
(7) (8) Diagram: Standard Collector with Bike or Parking Lane
"What does this section look like with Class II Bike Lanes on each side?" There would no
parking on the one side shown in the graphic, unless the street is a 1 -way street, in which case
both the parking and the bike lane could be accommodated on the street.
"What do we do if we need a center turn lane due to traffic volume?" The Public Works
Department would review the specific street volumes on the street to determine capacity issues.
If the study showed a need for a center lane, there would only be a striped center lane and a
travel lane in each direction and no bike lane would be striped. (This is a similar situation to the
Question 5 above.)
(9) Diagrams: Other Collector Design Options (showing 4 different collector design options)
"What do these sections look like with Class II Bike Lane on each side?" Three of the four
diagrams note that they are without bike lanes, so no bike lane would be present on either side
for the situations represented by those three diagrams. As to the one diagram labeled Residential
or Minor Commercial Collector (Special Conditions) w/ Bike or Parking Lane, the bike lane is
shown on the right-hand side. The Public Works Department would review the specific street
volumes, the needs for bicycle travel, and the needs for parking and determine whether a bike
lane or a parking lane would be placed in the 6 -foot area of the pavement. Note that this is a rare
road configuration usable only in special circumstances after a request of the developer.
(10) (11) Section: Minor Arterials with Alternative Design Standards
Subsection: Right-of-way 70 feet with four -lane section, five -lanes at major intersections
with additional right of way
"Same questions adequate capacity w/ 2 bike lanes?" The Public Works Department would
review the specific street volumes to determine capacity issues for motorized vehicle needs and,
if needed for motor vehicle travel, the 2 travel lanes would remain and no bike lane would be
required. (This is a similar situation to Question 3 above.)
"Will Bike Lanes be safe w/speed & Traffic?" The reason for a Class II Bike Lane rather than
just allowing bicycles to mix with motorized vehicles, as they are allowed to do by state law, is
to increase safety. (This is a similar situation to Question 4 above.)
(12) Section: Class I (with Road or without Road) Bike Paths
"What does this mean?" (We assume this question is about the nearby sentences stating that
Class I Paths are to be used when motor vehicle speeds or volumes are too high for Class II bike
lanes and where connections need to be made where no roadways exist, such as following a
creek bed.) The sentences mean that the Public Works Department would review the specific
street volumes and speeds on that particular street and if there were safety concerns about bicycle
travel, a Class I Path separated from traffic might be recommended. Class I Paths are also
recommended where connectivity is needed to ensure continuity of bicycle travel. The Bicycle
Plan now shows few Class I routes, with several such routes having been eliminated in the last
change to the Bicycle Plan accomplished in 2011.
(13) Section: Class II Bike Lanes
"Not consistent with cross sections." We do not see any inconsistency.
"Don't we need the turn lane for adequate capacity?" Please see the answer to Question #6
above, except this answer applies to a commercial street rather than a collector. Commercial
streets and collector streets share the same design standard.
(14) Section: Class III Bicycle Routes
"Do we show any Class III where speeds are 30+ MPH or 50% on capacity?" The bulk of
the streets where Class III Bicycle Routes are designated in the Master Bike Plan are collectors
and local streets. Local street design speed is 25 mph and for collectors is 30 mph. As to
capacity, as a general rule the City only regularly performs counts on arterials and intersections.
We do not, therefore, have this information. The Public Works Department will review the
speeds and volumes of specific streets prior to a bike route being marked, however.
(15) Section: Construction Standards (Bicycle Chapter)
"Are we going to bring existing Class I Paths up to these Standards? Do they meet them
now?"
As with all sections of the Master Street Plan, over time and as projects are proposed, the City is
working to implement all sections of the plan, whether it involves a street, sidewalk or bicycle
facility. Acquisition of property for Class I Bike Paths and construction to Class I Bike Path
standards will be accomplished by the City as it has grants or other funding available and as a
priority need arises.
(16) Section: Construction Standards (Bicycle Chapter)
"Total width is 18 feet - do our paths comply?" Class I paths have various widths depending
on whether they are to be 1 -way or 2 -way paths or have pedestrian use as well as bicycle use.
The maximum standard of 18 feet is only needed where 2 -way bike and 2 -way pedestrian travel
is required. Many of the current Class I Bike Paths, just as many of our city streets, are not
currently to full standard.
(17) Section: Construction Standards (Bicycle Chapter, footnote stating that if on -street
parking is desired, additional right-of-way and paving will be required, subject to Traffic
Engineering approval.)
"Please explain criteria for decision." As with any street, whether bicycle travel is or is not
involved, if a development wants on -street parking, the design must be reviewed by the City
engineers for safety, traffic movements, etc. { c;"
After you have had an opportunity to review the information, I would like to set-up a meeting
with you and staff to make sure that all the questions have been answered or address any other
issues that you might have.
If additional information is needed, please advise.
.PRINK PAL ARTERIALS,
FUNCTION: The primary function of a Principal Arterial is to serve through traffic and to
connect major traffic generators or activity centers within an urbanized area. Lower
design standards are required for Principal Arterials compared to Expressways. Since
these roads are designed for through traffic and are generally located three or more
miles apart, dedication of additional right-of-way is required to allow for future expansion
to six through lanes plus left and right turn lanes. Right-of=way of 110 feet is required
but may vary due to topography, floodway or other constraints eliminating or reducing
future adjacent development.
DESIGN: The standard Principal Arterial is to be used in all cases except where the City
Staff and Planning Commission find an unusual condition occurs. Some arterials have
special design standards. These arterials are listed on page 12.

MINOR ARTERIALS
FUNCTION: The Minor Arterials provide the connections to and through an urban area. Their
primary function is to provide short distance travel within the urbanized area. Generally these
roads are spaced at one mile intervals and have a right-of-way of 90 feet. Since a Minor Arterial
a high volume road, a minimum of 4 travel lanes is required: Current platted Master Street Plan
Minor Arterials are five lane sections. At the time of redevelopment via boundary street widening
platting or public funded reconstruction, a change in the section may be desirable. Applicants
wishing to change the five lane section to either a four lane section with bike lanes or a divided
four lane section may do so through an amendment to the Master Street Plan.
Newly created or existing Minor Arterials that have not been partially constructed may select
either of the three approved sections at the time of preliminary plat application. A lesser
standard may be acceptable:in areas of rugged topography or other areas where development
will be limited. This lesser standard can only be used in cases where unusual conditions would
substantially reduce or eliminate the amount of direct access to the road and substantially
reduce the density of surrounding development. The standard Minor Arterial is to be used in
all cases except where the City Staff and Planning Commission find an unusual condition
occurs. The curb cuts should allow both a continuous flow of traffic and access to adjoining
property. See page 15 for a list of Minor Arterials with special design standards.

COLLECTORS
FUNCTION: A Collector street is the traffic connection from Local Streets to Arterials or
to activity centers, with the secondary function of providing access to adjoining property.
The Collector system should not be continuous but should direct traffic to Arterials. This
class of road is generally at a spacing of a quarter to a half -mile.
DESIGN: The spacing of Collectors may be decreased and/or the right-of-way and
paving 'surface increased due to density of residential development and locations of
cornmercial areas or other large traffic generators. At the time of the subdivision, the
exact location and additional need for Collectors will be determined by the Little Rock
Planning Commission upon advice of the City Staff. Sidewalks are required on one side
'of Collector streets, but are required on both sides of Commercial Streets: Local public
streets which are abutted by non-residential zoning or use are considered "Commercial
Streets". In addition to non-residential zoning and use, if the adjoining land is more
Intense residential than duplex or two -unit residential, then the Local Street is a
Commercial Street. This type of street has a design standard (right-of-way, width, etc.)
the same as a Collector. Certain Collectors have special design standards. For a list:of
these Collectors, see page 19 .

CLASS I (WITH ROAD OR WITHOUT ROAD) BIKE PATHS
Class I bikeways or 'Bike Paths" are constructed and designed for the exclusive use of
bicyclists. These paths are completely separated from motor vehicle traffic. Bike Paths
are the safest for prevention of accidents with motorized vehicles.
The main advantage of a Class I Bike Path is the total separation between automobile
traffic and bicyclists. It is, in essence, a road for bicyclists designed to accommodate
speeds of up to 35 MPH with sharpturns and meandering pathways avoided whenever
possible. Class I Bike Path should be used when motor vehicle traffic volumes or
WMT
speeds are too high for Class II Bike Lanes, Class I (without road) Bike Paths are also DaEs THIS
necessary when connections need to be made where no roadways exist (such as
following a creek bed). a
While Class I Bike. Paths -are the safest and provide enjoyable rides, they are the most
costly to construct and maintain. A reliable and continuing maintenance program is
essential to the continued use and safety of the Bike element of the Master Street Plan.
Design of Class I (non -road or road) Bike Paths must be done with care:to insure safe
intersections avoiding bicycle -motor vehicle accidents.
GLASS II BIKE LANES NOT CONSISTENT WITH CROBS SECTIONS
Class II Bike Lanes consist of a paved area b th sldes of a roadway with a painted stripe
separating the bikeway from motor vehicle traffic, A Class 11 Bike Lane Is used for safety
reasons where mixing of bicycle and motorized vehicles is unsafe for both. These
routes may either be a smooth paved shoulder. or a section of the paved roadway. Class
II Bike Lanes require minimal construction and are likely to be located on higher volume
and vehicular traffic major roadways. Class Il Lanes on collector roads should use the
existing paved area. This'Would mean that in commercial areas with a Class..11 Lane, DON'T WE
only two traffic lanes would be allowed, except at intersections. Only a painted line on ABED THE -11M
the street separates bicyclists from motorists, additional pavement markings and LANE FOR ADEQu�
signage are requlrod. Class II Bike Lanes are easier to maintain and allow for maxlmuMATE C"ACITY'
design flexibility. Accommodations can be made for automobile parking between the l
bike lane and curb. where: street parking Is required. In orderto accommodate parking
on new (improved) roads. additional ROW and paving will be required If parking is
included. When space Is limited, parking may have to be restricted to one side of the
street.
CLASS III BICYCLE ROUTES
Class III Bicycle Routes have only special signage. These routes use the existing
vehicular area with no physical separatlon. Generally, Class I II Bicycle Routes -are local DCWE +aW
streets or higher class streets when speeds are less than 30 miles per hour and volumes;: CUSS III
less than half design volume.. Since there is no additional area, Class III Bicycle Routes WHERE SPEE09
have no additional maintenance requirements (except for signage). ARE 30+1 10H
The maln;disadvantage of Class III Bicycle Routes is that they provide the bicyclists with OR _50Z+ ON
minimal protection from vehicular traffic. Safety concerns make shared facilities C"ACITY
insufficient for high-speed streets with heavy traffic. Vq

CONSTRUCTION STANDARDS ARE WE GOING TO BRING EXIST-ING CLASS I PATHS
OF TO THESE STANDARDS? DO THEY MET THEM NOW?
Class I Bike Paths may have an initial construction phase with a lesser standard. These
routes should be designated "Development Routes", Any Development Route must be
constructed with industrial sand or screening of 100% crushed material or compacted
soil. Off-road (large wheel) or mountain bikes will be recommended for these paths. In
all cases the path must be constructed so it will properly drain.
Class I Bike Paths should be constructed to be permanent. Proper drainage is important
to prevent standing water on the route. Construction should be of 2" flexible paving on a
compacted 4" gravel base or 4" flexible paving on compacted or undisturbed suitable
soil. A sloped surface of 1/4" in 1 foot will allow for drainage,
Paths should be constructed at least 10 feet from large trees to minimize root damage to
paths and decrease the possibility of a cyclist/tree collision. For safety, separate paths
should not run immediately parallel and adjacent to streets.
A one way bike path, while not recommended should be minimum of 5 feet wide, and a
two way path should be at least 10.0 feet wide with a strlpe down the middle to separa
the two lanes, For Class I Bike Paths, non -road, routes where pedestrian traffic is u�
expected,. separate lanes 4 feet wide should be constructed for their use. TOTAL WIDTH I9 18"
Class I Bike Paths build as part of an arterial will require an additional 10 feet of right -of- DO OUR PATHS
way (5 foot each side for one-way path) or an easement in which the path is placed. COMPLY?
The required sidewalk along these streets can be incorporated into the bike path. The
result would be a 9 -foot wide path on each side of the road. A four -foot section of the
path should be marked for pedestrian use.
Class II Bike Lanes should be of the same construction as the streets on which they are
constructed. The minimum width Is 6 feet from back of curb. If roadway shoulders are
used for'Bicycle Lanes, the shoulder :should be 5 feet wide. This width should
discourage vehicular traffic use and keep the path free of debris,
Class III Bicycle Routes are part of the street. No additional construction is required,
The AASHTO "Guide for Development of Bicycle Facilities (1991) Is the recognized
standard for bikeway design and should be utilized by bikeway designers.

Response to Master Street Plan Questions:
The questions presented are Master Street Plan questions and generally fall into a few similar
categories. They deal with the various street cross-section diagram options for various road
types — either the even number of lanes or odd number of lanes. A second group of questions
ask how the City would address alternative right-of-way or alternative surface area arterial. A
third set deal with capacity and lane marking issues. Then there is a group of questions that
ask about the design standard for bicycle facilities various existing conditions.
(1) Principal Arterial Design Standards Stage 2 (final) construction (Design Standard chapter
Master Street Plan — 6 -lane divided)
"What does this section look like with Class II Bike Lane? Will we have adequate long term
capacity with just two lanes for traffic?" The Bike Lane would be striped along the outer lane.
The Public Works Department would review the specific street volumes to determine capacity
issues for motorized vehicle needs and if needed - the three travel lanes would remain and no
bike lane would be required.
(2) Initial Construction of Principal Arterial (Design Standard chapter Master Street Plan — 4 -lane
divided)
"What does this section look like with Class II Bike Lane?" The Bike Lane would be striped
along the outer lane. The Public Works Department would review the specific street volumes to
determine capacity issues for motorized vehicle needs and if needed - the two travel lanes
would remain and no bike lane would be required.
(3) Principal Arterials with Alternative Design Standards (90 Right-of-way with 5 lanes)
"Some of these streets are shown as Class II Bike Lanes will these alternate sections have
adequate capacity w/bike lanes marked out in each direction?" The Public Works Department
would review the specific street volumes to determine capacity issues for motorized vehicle
needs and if needed - the two travel lanes with center turn -lane would remain and no bike lane
would be required.
(4)"Will the Bike Lanes be safe with the speeds and traffic" The reason for a Class II Bike Lane
rather than just allowing bicycles to mix with motorized vehicles is to increase safety.
(5) Minor Arterials (5 -lane design standard)
"Where do we place the Class II bike Lanes when we need this section based on traffic
volume?" The Public Works Department would review the specific street volumes to determine
capacity issues for motorized vehicle needs and if needed - the two travel lanes with center
turn -lane would remain and no bike lane would be required.
(6) Other Minor Arterial Design Options:
"Bike Lanes?" The Bike Lane would be striped along the outer lane. The Public Works
Department would review the specific street volumes to determine capacity issues for motorized
vehicle needs and if needed - the two travel lanes would remain and no bike lane would be
required. "What do we do if we need the center turn lane for driveway traffic?" The Public
Works Department would review the specific street volumes to determine capacity issues for
motorized vehicle needs and if needed - the two travel lanes with center turn -lane would remain
and no bike lane would be required.
(7) (8)Collectors
"What does this section look like with Class II Bike Lanes on each side?" There would no
parking on the one side shown in the graphic. "What do we do if we need a center turn -lane due
to traffic volume?" The Public Works Department would review the specific street volumes to
determine capacity issues for motorized vehicle needs and if needed - the travel lanes with
center turn -lane would remain rather than travel lanes with bike lane would be striped.
(9)Other Collectors
"What do this sections look like with Class II Bike Lane on each side" As noted on the page
(Page 18) these are options and some show a bike lane option some show roads without bike
lanes.
(10) (11) Minor Arterials with Alternative Design Standards (Right of -way 70 feet with four lane
section)
"Same questions adequate capacity w/2 bike lane?" The Public Works Department would
review the specific street volumes to determine capacity issues for motorized vehicle needs and
if needed - the two travel lanes would remain and no bike lane would be required. "Will Bike
Lanes be safe w/speed & Traffic?" The reason for a Class II Bike Lane rather than just allowing
bicycles to mix with motorized vehicles is to increase safety.
(12) Class I (with road or without road Paragraph — p33 of Master Street Plan)
"What does this mean?" (Assuming question is about sentences dealing with Class I Paths
when volumes or speeds too high for Class II) The Public Works Department would review the
specific street volumes and speeds and if there were safety concerns a Class I Path might be
recommended.
(13) Class II Bike Lanes paragraph - page 33 Master Street Plan
"not consistent with cross sections" See responses above "Don't we need the turn lane for
adequate capacity?" The Public Works Department would review the specific street volumes to
determine capacity issues for motorized vehicle needs and if needed - the travel lanes with
center turn -lane would remain rather than travel lanes with bike lane would be striped.
(14) Class III Bicycle Routes paragraph - page 33 Master Street Plan
"Do we show any Class III Where Speeds are 30+ MPH or 50% on capacity?" These numbers
could change over time, the Public Works Department will review the speeds and volumes of
specific streets at the time a bike route is marked and as needed into the future as with any
street where a bike facility is located on it or not.
(15)Construction Standards section Master Street Plan Bicycle chapter — Page 34
"Are we going to bring existing Class I Paths up to these Standards? Do they meet them Now?"
As with all sections of the Master Street Plan as projects are proposed and over time the City is
working to implement all sections of this document whether a street, sidewalk or bicycle facility.
(16)"Total with is 18 feet do our paths comply?" Class one paths have various widths
depending on if there are one-way or two-way or have pedestrian use as well as bicycle use.
Many of the current Class I Bike Paths just as many of our City Streets are not currently to full
standard.
"Please Explain Criteria for Decision?" (This is on a footnote about on -street parking) as with
any street if a development wants on -street parking the design most be reviewed by the City
Engineers for safety, traffic movements, etc.
