In addition to indicating the
surface condition of a road,
a given rating also includes a
recommendation for needed
maintenance or repair. This
feature of the rating system
facilitates its use and enhances
its value as a tool in ongoing
road maintenance.

SCANDIA
• 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
ALTERNATIVE MAINTENANCE
• 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 MAINTENANCE
• 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
• 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 RECONSTRUCTION
• 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

• Planning- Current Shortfalls
• Long-term CIP will need annual review and revisions.
• Need to account for roads not currently programed or roads planned so far into
the future conditions will change before we get to construction.
• Planned improvements 2026 or later and/or not planned:
• 2026 - Oxboro Ave N and Oxboro Lane
• 2028 - 199th Street N, Parkview Lane, and Parkview Ave 23&hST.N.

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.
