N
• League of Minnesota Cities - Response
• The city has broad and substantial authority to manage street design,
construction and maintenance within Scandia.
■ Minn. Stat. 412.221, Subd. 6
(https://www.revisor.leg.state.mn.us/statutes /?id=412.22 ): The City
"council shall have power to lay out, open, change, widen or extend streets,
alleys, parks, squares, and other public ways and grounds and to grade,
pave, repair, control, and maintain the same...."
The City does have a duty to maintain streets so that they are safe for public
use and travel, but there are no specific standards about width etc. for
existing city streets. Here is a link to the League's Information Memo on
Maintenance and Acquisition of City Streets which discusses these issues in
more detail):

PAVEMENT MANAGEMENT
• Local Rural and City Pavements in Growing Communities
• Initial pavements are often minimal strength for local streets -Shape and pave
existing gravel roadways.
• Often managed somewhat informally, or managed re -actively.
• Paved roadways tend to deteriorate more rapidly after the initial tens years of
lifecycle without scheduled maintenance programs.
• Pavement Management
• The process of planning the maintenance and repair of a network of roadways
or other paved facilities in order to optimize pavement conditions over the
entire network.

SCANDIA
PAVEMENT MANAGEMENT
• Construction Methods - Seal Coating
• Includes applying a polymer modified asphalt emulsion & embedding finely
graded aggregate into the surface.
• Protects pavement from the deteriorating effects of sun and water
• When bituminous pavements are exposed to sun, wind, and water the surface begins to
oxidize. This causes pavements to become brittle.
• Provides a waterproof membrane which not only slows down oxidation process but also
helps the pavement shed water, preventing it from entering the base material.
• Used to provide anew wearing surface on roadways that increases friction
• Application on average will last about 7 years
SCANDIA
PAVEMENT MANAGEMENT
• Construction Methods - Micro Surfacing / Slurry Seal
• Micro surfacing is a cold -applied paving mixture composed of polymer -
modified asphalt emulsion, crushed aggregate, mineral filler, water and a
hardening -controlling additive. No rolling is required and the finished surface
can generally be opened to traffic soon after placement.
• Like seal coating, micro surfacing can be used as a blanket cover on
placements suffering from loss of skid resistance, oxidation, raveling, and
surface permeability. Also can be used to fill in minor ruts and improve
rideability by removing minor surface irregularities.
• This treatment can last on average 8 to 9 years
SCANDIA
PAVEMENT MANAGEMENT
• Construction Methods - Mill & Overlay
Street maintenance technique that requires the removal of the top layer (1
2 inches) of a street by grinding action of a large milling machine. After the
top layer is removed, a new layer of bituminous pavement is put in its place.
• Need adequate structure below top layer to support construction equipment.

SCANDIA
PAVEMENT MANAGEMENT
• Construction Methods - Full Depth Reclamation (FDR)
• FDR is an in-place recycling alternative to road reconstruction. It uses a
powerful reclaiming machine to turn an old asphalt pavement into a road base
by uniformly pulverizing that full thickness of the old pavement and blending it
with a portion of underlying material.
SCANDIA
PAVEMENT MANAGEMENT
• Construction Methods - Full Reconstruction
• Includes removal of existing roadway by sub -cutting and reconstructing of the
road section from the sub -grade to the final wear course.
• Sometimes sub -grade correction work is required

Funding- Options
General Funds
Money raised from annual City property taxes
Special Assessments
Indirect form of taxation. They are compulsory charge on selected properties for a
particular improvement or service that benefits the owners of the selected property.
The Courts insist on strict compliance with the special assessment procedural requirements.
Increasingly, residents are more willing to challenge special assessments.
Bonds
City streets can be financed through bonding alone or in combination with special
assessments.
Variety of bonds City can choose from, recommended City consult specialized bond Counsel
to help determine the bond best suited to the City's needs.
Franchise Fees
A franchise fee is a charge imposed by the City on utility and cable providers who operate in
the public right-of-way. An agreement with the City allows them to work in the right-of-way
upon payment of established fees.
Developments Agreements
New developments being subdivided in accordance with the City subdivision ordinance, a
City may condition its approval of the subdivisions upon the construction and installation of
streets by the sub -divider.

• Next Steps
• Start Communication.
■ After frost is out of ground (typically end of April or early May), complete field review.
• Recommend roads to have soil borings completed.
• Revise Capital Improvement.
