Capital Improvement Program 2014-2018 & Consideration of Policy Changes General Business 4• D. 1• SHAKOPEE 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.

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.
