TO: Mayor and City Council
Mark McNeill, City Administrator
FROM: Bruce Loney, Public Works Director
DATE: 07/29/2013
SUBJECT: Capital Improvement Program 2014 -2018 & Consideration of Policy Changes. (E)
Action Sought
Present to Council the Capital Improvement Program for 2014 -2018 including potential projects that require policy
change from the City Council and provide staff direction.
Background
Public Works staff has prepared 2014 -2018 Capital Improvement Program which includes projects within the
Sanitary Sewer, Storm Drainage, and Street Improvement areas. This memo is intended to inform the Council of
potential projects within the sanitary sewer and storm drainage areas that would require policy changes on behalf of
the City Council.
Sanitary Sewer Policy Change in regards to Sewer Service Improvements
Staff has included in the Capital Improvement Project (CIP) a project to consider lining of sanitary sewer services
that are connected to sanitary sewer mains that have been lined from 2006 to the current date. Attached to this
memo is a map showing areas that have been lined and at what year and also a map showing when the sanitary
sewers were installed initially.
The current policy with replacement of sanitary sewer mains and sewer services as part of the reconstruction project
is to not access those replacements but pay them out of their sanitary sewer enterprise fund. Essentially with the
reconstruction project the sewer main and the associated services to the property line will be brand new and paid
out of the sewer fund.
The current policy also is that the property owner is responsible for the sewer service line from the building to the
sewer main. If the sewer service fails, the property owner is responsible to fix it at their cost.
Recently, the City has lined several sewer lines to extend the sewer main life with essentially a PVC liner that
would extend the life to fifty years or more. Sewer services connected to these mains might be as old as fifty years,
but generally around the thirty to forty year range. A possible project for consideration is to line the sewer services
on the sewer main that has been lined in order to extend the life of the sewer services within the public right -of -way
to the same age as the main.
Staff has been in contact with other cities and consultants who have done these types of projects and there are ways
to line the sewer service at minimal excavation work at the property line. The cost generally can range between
$3500 and $4500 per service. Also in these types of projects, the homeowners can elect to have their sewer service
lined to their building but would be assessed the cost of that lining from that property line to their building.
Current estimate of services connected to line sewer main is 683 services and at $4500 per service. The cost to line
every service is approximately $3 million. Current balance within the sanitary sewer fund is over $15 million.
The rationale for using the sanitary sewer fund is if the sewer main was to be replaced by excavation, the sanitary
sewer services would also be replaced and paid out of the sewer fund. Also, by lining the sewer services, the amount
of excavation in those streets would be minimized and our future street reconstruction project would entail only
replacing the street pavement and maybe the curb and gutter, if warranted. Staff would estimate in order to meet the
project size to get good volume prices from a contractor would be between 100 -150 services. Thus, this program
could be done over a 4 -5 year period.
The Second Policy would be a Concrete Alley Program
The City of Shakopee has approximately eleven miles of alley in the old urban Shakopee area. Many of these alleys
are unpaved with most of the alleys that are paved within the Central Business District or in areas petitioned by
property owners.
In the old Shakopee Plat, there are no drainage and utility easements along lot lines with the only drainage
easement for many of these blocks is the alley right -of -way which is generally 16 feet in width. Many of these
alleys are very flat and do not transmit water very well except through neighboring properties. In the spring of the
year, staff has received many complaints of the water within the alleys not draining out and making the alley very
difficult to drive through.
Current policy for paving an alley is for the City to receive a petition from 100% of the affected property owners
and assess 100% of the cost if they want to upgrade from existing gravel to having paved. Reconstructing of
existing pavements would also be assessed 100% except in the Central Business District where the Council can
determine the amount assessed at the public hearing. City Council in past years have assessed 25% of the alley
pavement cost in the Central Business District, thus would explain there are more paved alleyways in Central
Business District than anywhere else.
Staff would like Council to consider a concrete alley program in which residents or property owners can petition the
City with a minimum of 35% of the property owners. The concrete alley would be an inverted crown pavement
section which would also transmit water from the alley to the storm sewers or street sections of the City. Staff
would also like Council to consider a revised assessment policy to perhaps a 25% assessment or a maximum
amount for residential while maintain a 25% assessment to commercial and multi - family units. The remaining
portion of the project could be funded under the storm drainage system as the alleys are being improved to collect
water and transmit water to the storm drainage system.
Staff does feel there is benefit for the storm drainage system but also benefit for the property owners for getting an
improved alley which can be utilized for the entire year. Average cost for an alley is estimated between
$50,000- $60,000 per block. There are approximately 11 miles of ally in the City and staff would propose a program
that would be at least ten to twelve years in duration doing approximately ten to twelve blocks of alley per year. The
estimated cost for the storm drainage system for a twelve year program would be approximately $6 million if every
alley was to be included in the program.
Staff is bringing this program to Council for consideration due to the amount of issues we have with alleys and
drainage particularly in the Lewis Street area and along 2nd and 3rd Avenues.
Recommendation
Staff would recommend consideration of the lining of sewer services by proposing that a feasibility study be done
during the winter months of this year to see if this program can move forward. Staff also would recommend that
Council provide direction for a concrete alley program and whether to pursue a program at this time. A feasibility
study was be appropriate for a concrete alley program and associated policy changes.
Budget Impact
Lining of existing sewer services would be out of the Sanitary Sewer Fund. The proposed concrete alleys would
paid out of a combination of assessments and surface drainage fund.
Relationship to Vision
This supports Goal E — "Deliver effective and efficient public services by a staff of well- trained, caring, and
professional employees ".
Requested Action
Present to Council the Capital Improvement Program for 2014 -2018 including potential projects that require policy
change from the City Council and provide staff direction.

will be deducted from the total project cost and assessed to the property receiving lateral
benefit from the trunk sewer extension.
• Oti erdepth — The incremental cost to construct a lateral sanitary sewer to be
extended to another subdivision greater than a depth - necessary to serve the development
or 12 feet, whichever is greater, and the most upstream point of the lateral shall be
considered an overdepth cost and will be paid for by the City from the Trunk Sanitary
Sewer Fund. The cost of the installation of the pipe at a minimum depth of 12 feet will
be assessed against the property receiving benefit from the lateral extension.
In the event that a trunk sewer is to be extended across a new subdivision with the intent
to provide service to undeveloped property, lateral benefit shall be determined by the City
for determining the application of payment for that lateral benefit. Payment could consist
o f an assessment or as a lateral connection charge.
In situations where a trunk sewer is extended across developable property that the cost
of the lateral benefit to that particular property be collected at the time of development
through a lateral connection charge or special assessment as approved by the City
Council.
In situations where sanitary sewers will be assessed, lateral sanitary sewers will be
assessed on a basis to be determined by the City Engineer.
Major trunk sewers or interceptors will be funded through charges to the entire drainage
basin benefited by the sewer. This will be collected as trunk charge or connection charge
in accordance with the City Trunk Sanitary Sewer Policy. Funds collected from this fee
shall be retained in the Trunk Sanitary Sewer Fund to be used for trunk related costs.
The replacement of existing sewers will not be assessed but rather paid for 100% by the
City using either the Sanitary Sewer Enterprise Fund or other funding sources identified
by the City Council. Should the nature of the development require upgrading of existing
pipes due to capacity limitations, the incremental cost between the existing pipe size and
the upgraded pipe shall be assessed to the development initiating the improvement.
Existing sanitary sewer service lines replaced, as part of a project that includes sanitary
sewer main line replacement, will not be assessed.
Individual service lines installed directly to specific properties will be fully assessed
directly to the benefited properties. Properties that have existing sanitary sewer services,
but do not have main line sewers adjacent, across or up to their property lines will pay
50% of the assessment rate for the new main line sanitary sewer with the cost associated
with replacing existing sanitary sewer service lines not assessed.
Any existing service line found to be defective, as part of a street reconstruction in which
the main line sewer is not being replaced, shall be replaced as part of the project and
assessed directly to the property.
