Current through Register Vol. 47, No. 6, September 18, 2024
(1) Construction.
a. The
department shall be responsible for all right-of-way and construction costs to
construct nonfreeway primary highway extensions to the minimum design criteria
as established by the department. Construction improvement costs beyond minimum
design criteria shall be the responsibility of the city, as specified in the
project agreement. Minimum design criteria shall be in accordance with "A
Policy on Geometric Design of Highways and Streets, 2018" (Seventh Edition
AASHTO Green Book).
b. The city
shall be responsible for providing, without cost to the department, all
necessary rights-of-way that involve dedicated streets or alleys.
c. The city may be responsible for providing,
without cost to the department, all necessary rights-of-way that involve other
city-owned lands, except parklands, subject to the condition that the
department may reimburse the city for the functional replacement value of
improved property and advanced purchases negotiated by the city for project
purposes.
d. The city shall take
all necessary legal action to discontinue and prohibit any past or present use
of project rights-of-way for private purposes. The city shall prevent any
future encroachment or obstruction within the limits of project
rights-of-way.
e. The department
shall be responsible for the costs of construction of longitudinal and outlet
storm sewers made necessary by highway construction and construction of local
service roads developed as a part of the construction or reconstruction of the
through traffic lanes in the proportion that the right-of-way of the primary
road extension bears to the total drainage area to be served by the proposed
sewers. The city shall be responsible for the remaining portion of storm-sewer
costs not paid for by the department.
f. Unless otherwise mutually agreed to and
specified in the project agreement, the department shall be responsible for the
cost of acquiring rights-of-way and construction of local service roads
developed as a part of the construction or reconstruction of the through
traffic lanes.
(2) Maintenance. The department shall enter into an agreement with a city regarding the maintenance of primary roads within the corporate city limits. This is intended to include corporate line roads, when appropriate. Unless otherwise mutually agreed to and specified in the agreement, the maintenance of nonfreeway primary highway extensions within the corporate city limits, including corporate line roads, shall be as follows:
a. On primary roads constructed with a curbed
cross section, the department shall be responsible for:
(1) Maintenance and repairs to pavement and
subgrade from face of curb to face of curb exclusive of parking lanes,
culverts, intakes, manholes, public or private utilities, sanitary sewers and
storm sewers.
(2) Primary road
signing for moving traffic as set out in subrule 150.4(1), pavement markings
for traffic lanes, guardrail and stop signs at intersecting streets.
(3) Surface drainage only, within the limits
of pavement maintenance.
(4)
Plowing of snow from the traffic lanes of pavement and bridges and treatment of
traffic lanes with abrasives and chemicals.
(5) Inspection, painting and structural
maintenance of bridges as defined in Iowa Code section
309.1.
b. On primary roads constructed
with a rural cross section (no curb), the department shall be responsible for
all maintenance, except tree removal, sidewalks, retaining walls and repairs
due to utility construction and maintenance shall be the city's
responsibility.
c. On primary roads
constructed with a curbed cross section, the city shall be responsible for:
(1) Maintenance and repairs to pavement in
parking lanes, intersections beyond the limits of department pavement
maintenance, curbs used to contain drainage, and repairs to all pavement due to
utility construction, maintenance and repair.
(2) Painting of parking stalls, stop lines
and crosswalks, and the installation and maintenance of flashing lights.
Pavement markings shall conform to the MUTCD.
(3) Maintenance of all storm sewers,
manholes, intakes, catch basins and culverts used for collection and disposal
of surface drainage.
(4) Removal of
snow windrowed by departmental plowing operations, removal of snow and ice from
all areas outside the traffic lanes, loading or hauling of snow which the city
considers necessary and removal of snow and ice from sidewalks on bridges used
for pedestrian traffic.
(5)
Maintenance of sidewalks, retaining walls and all areas between curb and
right-of-way line.
(6) Cleaning,
sweeping and washing of streets.
(7) Maintenance and repair of pedestrian
overpasses and underpasses including snow removal, painting and structural
repairs.
(8) Maintenance and repair
of bicycle overpasses and underpasses including snow removal, painting and
structural repairs.
d.
The city shall comply with the access control policy of the department as
adopted in 761-Chapter 112 and obtain prior approval from the department for
any changes to existing entrances or for the construction of new
entrances.
e. Drainage district
assessments levied against the primary road within the corporate limits of the
city shall be shared equally by the department and the city.
f. Should local service roads or streets be
constructed as a part of a project, upon completion they shall become a part of
the city street system. The department shall not be responsible for the
maintenance of these roads or streets and corresponding drainage
structures.
(3) Lighting.
a. The department
shall not be responsible for the installation, energy, and maintenance costs of
lighting on extensions of nonfreeway primary highways. The city may elect to
provide lighting at its own expense. However:
(1) For cities with a population of 5,000 or
less, the department may elect to install interchange lighting and to be
responsible for or to participate in the energy and maintenance costs of this
lighting.
(2) On a new construction
project that results in a predominately fully controlled access highway, but
incorporates some nonfreeway segments, the department may elect to participate
in the installation of lighting at conflict points if the city agrees to be
responsible for the energy and maintenance costs of this lighting.
b. At corporate line primary road
junctions, the lighting shall be installed where necessary by the department in
accordance with department warrants. The department shall be responsible for
the installation costs. Unless otherwise agreed, the energy and maintenance
costs shall be shared by the city and department in proportion to the number of
luminaires in each jurisdiction as established by the corporate line. When and
if the corporate line is extended to include any part of the lighting
installation or a greater proportion of luminaires, the proportionate costs for
maintenance and energy shall be redetermined on the basis of the number of
luminaires in each jurisdiction as established by the new location of the
corporate line.
(4) Traffic signals.
a. All
traffic signal installations shall meet the standards and warrants established
in the MUTCD.
b. On projects
initiated by the department, the department may install, at no cost to the
city, traffic signals warranted when replacing existing pavement or adding new
lanes. In conjunction with these projects, the department may also participate
in the cost of signals that are for pedestrian use only. If the department
participates, the department's share of the installation costs shall be based
on the current U-STEP cost apportionment.
c. When new pavement construction or
additional lanes are not involved, the department may participate in the
installation costs of new and modernized traffic signals or signals that are
for pedestrian use only. If the department participates, the department's share
of the installation costs shall be based on the current U-STEP cost
apportionment; the city shall prepare plans, award the contract, supervise the
installation, and be responsible for the remaining installation
costs.
d. Modifications made to the
traffic signal system to coordinate it with other city signal systems (not on
the primary road extension system) shall be the sole financial responsibility
of the city.
e. The department
shall not participate in the cost of signals for commercial use only.
f. The department shall not
participate in the signalization of primary road stub routes which terminate
within the city.
g. The department
shall not assume ownership and shall not be responsible for any energy or
maintenance costs for traffic signals.
h. Signal phasing, initial and future, as
well as timing and coordination between intersections shall be coordinated
between the department and the city.
(5) Overdimensional and overweight vehicles. The city shall comply with all current statutes, rules and regulations pertaining to overdimensional and overweight vehicles using primary roads when issuing special permits for overdimensional and overweight vehicles.
