Background: Approximately three years ago the Fire Chiefs of Richfield, South St. Paul, West St. Paul, Eden Prairie, Mirmetonka, St. Louis Park and Columbia Heights began meeting and discussing the current Primary Service Areas (PSA) for the Advanced Life Support (ALS) Ambulance Transportation System. The consensus among the group was that the..- current system is a monopoly, at a minimum. Should one of our departments decide to get into the transportation business, it would be literally impossible. Should one of our departments try to get the PSA for our area for non transportation purposes but for regulation of services and finances, it would also be impossible under the current system. Following is a list of issues for PSA Cooperative Service Agreements. Customer Service: Allows a city to be responsive to citizens needs and desires. Local Control: A city should be allowed to provide this public safety service just like they are allowed to provide police and fke services. A city has no say or input in the ambulance provider unless it gains ownership of the PSA. Fairness'& Equity_: Other cities are allowed to provide this "better" service to their citizens (Edina, Bumsville, White Bear Lake, Maplewood, Woodbury, Virginia, Hibbing, St. Paul, Red Wing). Efficiency: Utilizing cross-trained multi-tasked firefighters is a more efficient use of personnel who are already responding to the incident. These are just a few reasons why the City of Columbia Heights should support legislation with the multiple other cities to gain ownership of the ALS PSA in our community. Understand fully that just because we own the PSA does not mean we would need to transport patients in an Advanced Life Support manner. Having ownership of this PSA would give us the opportunity to conduct an in-depth study on whether we should get into the transportation business. The biggest advantage of owning the PSA is that we would have control over who provides the transportation services and what they charge for their services. My recommendation is that we pursue the PSA legislation with the understanding that this will not automatically put us in the transportation business but more importantly gives us local control over this service, as we should have. RECOMMENDED MOTION: Move to Waive the Reading of Resolution 2004-09, There Being Ample copies Available to the Public. RECOMMENDED MOTION: Move to Adopt Resolution 2004-09, Authorizing Support of Legislation Allowing Columbia Heights to Control how Advanced Life Support Services in the City of Columbia Heights are provided. 04~20 COUNCIL ACTION: RESOLUTION NO. 2004-09 BEING A RESOLUTION AUTHORIZING SUPPORT OF LEGISLATION ALLOWING'COLUMBIA HEIGHTS TO CONTROL HOW ADVANCED LIFE SUPPORT SERVICES IN THE CITY OF COLUMBIA HEIGHTS ARE PROVIDED. WHEREAS, the City Council of the City of Columbia Heights desires to have control over how Advanced Life Support service is provided to the citizens of Columbia Heights, and; WHEREAS, the City of Columbia Heights should be allowed to control Advanced Life Support services as it is allowed to control how other Public Safety Services are provided, and; WHEREAS, the City Council believes special legislation is required to allow the City of Columbia Heights to acquire jurisdiction to control Advanced Life Support services. NOW, THEREFORE, BE IT RESOLVED, that the City Council of the City of Columbia Heights supports legislation to achieve this objective. Adopted this 23ra day of February, 2004. Offered by: Seconded by: Roll Call: CITY OF COLUMBIA HEIGHTS Patricia Muscovitz, Deputy City Clerk Mayor, Julienne Wyckoff CITY COUNCIL LETTER MEETING OF: FEBRUARY 23, 2004 AGENDA SECTION: CONSENT ORIGINATING DEPT: CITY MANAGER NO: FINANCE APPROVAL SYSTEM FOR LIQUOR OPERATION (~t.~) ~ NO: DATE: 02/10/2004 The current cash register system in the liquor operation was purchased in August of 1991. At that time it was anticipated that the system would last between seven and 10 years. The system has gone well beyond those expectations and has lasted in excess of 12 years. However, virtually all portions of the system are wearing out and becoming highly undependable. During the year 2003 we spent over $3,800 on service calls for repairs to the system. In addition to this, staff spent a countless number of hours manually recalculating data and correcting errors that the cash register system had generated. Based on these problems, staff contacted several companies and requested proposals for a new cash register system for the liquor operation. Eight different systems from four different companies were reviewed and analyzed. Based on the proposals and staff's analysis of the various systems, it is staff's determination that the S4 Windows version offered by Retail Data Systems at a cost of $59,850 is the most cost-effective solution to our needs. Attached is a memo from the Finance Director that goes into more depth as to what is needed in a cash register system for the liquor operation. RECOMMENDED MOTION: Move to authorize the Mayor and City Manager to enter into an agreement with Retail Data Systems for the purchase and installation of the S4 Point of Sale cash register system based on their written proposal at a cost of $59,850. WE:sms o4o2102COUNCIL Attachment COUNCIL ACTION: CITY OF COLUMBIA HEIGHTS DATE: FEBRUARY 10, 2004 TO: WALT FEHST CITY MANAGER FROM: WILLIAM ELRITE FINANCE DIRECTOR RE: LIQUOR OPERATION CASH REGISTER SYSTEM The current cash register system in the liquor operation was purchased in August of 1991. At that time it was anticipated that its life expectancy would be seven to 10 years. The system has greatly exceeded that expectancy in that it has lasted over 12 '/2 years. However, in the last year we have had significantly more problems and more breakdowns. In 2003 we spent nearly $3,800 on service calls for repairs to the system. In addition to that, a tremendous amount of staff time was spent manually recalculating data due to problems in the system where data was lost. Based on this, we have reached a point where it is essential to upgrade to a new system. Larry Scott and Brian Hachey researched systems that are in use in other liquor operations and then contacted four vendors to obtain proposals for a new cash register system. Attached is a list of the vendors contacted and the cost of the various systems. The current system that we have in operation was purchased from Retail Data Systems. It is a Casio cash register system operating with an S4 computer program. In essence, the cash registers are all linked to a central computer that maintains all of the data files and information. The recommended replacement system is also from Retail Data Systems and uses a new version of the S4 software. By staying with the same vendor and the same software we will be able to transfer all of our previous data on sales and merchandise to the new system. This is a valuable advantage as this data is used on a regular basis for purchasing, marketing, and the general management of the liquor operation. Also, Retail Data Systems has proven to be a very reliable and dependable vendor and they have provided us with good customer support since we opened Top Valu in November of 1984. The cash register Point of Sale system in the liquor operation is a very intricate structure. The Point of Sale software serves three very essential functions or purposes. First, it retains the retail selling price of all merchandise and handles each sales transaction, properly pricing the merchandise, adding sales tax, and retaining the sales data. This is the heart of the system as it provides service to our customers and retains the data needed for the other functions of the system. The second function of the system is to maintain proper accounting and inventory control records to insure that we have proper accountability and tracking of sales and merchandise inventory. This function is essential for maintaining proper internal control over the assets of the City. The third aspect of the system is to provide the liquor operations manager with detailed data regarding merchandise sales, gross profit margins, and to furnish the operations manager with the information that is needed to purchase proper quantities of merchandise on a timely basis. The operations manager needs the quick availability to look at prior sales of individual items and categories of items to enable him to purchase in a timely and cost-effective manner.. This is the area where there is the greatest degree of difference in Point of Sale systems. It is also the area that can have the greatest effect on profits in the liquor operation. Purchasing in a timely, cost-effective manner can only be accomplished by having good historic sales information readily available. In summary, the Point: of Sale cash register system is one of the most essential parts of the overall liquor operation in maintaining control and profitability. After reviewing the various systems, staff is convinced that the Retail Data Systems S4 Point of Sale system is the most cost-effective solution to the needs of the liquor operation.

Hansen~L0 ) BY: Backups DATE: 2/10/~~'~"-'~ DATE: Bm'kground: The City of Columbia Heights sanitary sewer system has periodically experienced surcharging at various locations throughout the City and at various times in the last 30-40 years. A consequence of this is flooding or backups into private properly through the sanitary ~ewer services. The most recent of these occurred in 2003 after a severe rainfall the evening of June 24th and early morning of June 25, measuring 5.47 inches of rain in a 3-hour period (exceeding a 100-year storm event). As a direct result, several areas of the City ~enced localized flooding from surface water and sanitary sewer system overload (backups). The area with the most severe backups was in the Jackson Pond area. The following represents a review of the existing conditions in the Jackson Pond area, and presents a short and 1,o~ term plan for consideration by the Council to address the flooding problems and the concerns raised by residents at the June 30 , regular Council meeting. Aaalysis/Conclusions: This report will focus on sanitary sewer flooding, and does not address surface water flooding issues, due to the fact that sanitary sewer backups occurred when the storm event greatly exceeded an acceptable level of protection, or a 100-year storm event. Sanitary sewer backups were mainly concentrated, and most severe, in the area around Jackson Pond. The backups in the affected homes varied from just around the floor drain to over 15 inches of gray water in the entire basement. Due to the type of storm, high intensity large peak, and the short lag time to when backups occurred in this area, system inflow and to a lesser extent infiltration are believed by staffto be the likely cause. Inflow and infiltration (I/I) is unnecessary water that enters the sanitary sewer system, but can be completely separate in origin. Inflow is storm water runoffor any other surface water that flows through a direct connection to the sanitary system. This may occur as a result of connected downspouts, area drains, holes in the manhole covers, cross connections from the storm sewer, or connected sump pumps. Infiltration is groundwater that enters the sanitary collection system through cracked pipes, leaky joints and deteriorated manholes. A graph depicting the relationship of I/I to regular sanitary sewer system flow is attached as figure 1. ~[o meet mandated federal requirements, the City conducted an I/I study in 1983. The study noted that 'many of the rainfiall related problems associated with inflow occur in the Jackson Pond area,' and 'basements have backed up 7 times in thc last thrcc years and approximately 22 to 25 residents are affected by a 1-1/2 inch per hour rain.' The study concluded that the City of Columbia Heights does not have a major I/I problem, and that 'thc system is adequate to handle thc peak-flow rates generated during the design sto~,' but that certain areas (5 of 15) of the City may benefit from a flow reduction program. A flow reduction program was identified recommending comprehensive cleaning and televising, manhole lid/frame replacements, linings of sanitary sewer, and inflow reduction. The estimated cost to perform all of the recommendations in the report to reduce I/I was $5,688,020 (1983 dollars). The City of Columbia Heights has performed and continues to implement many of the recommendations of the 1983 report. One of the questions raised by a Councilperson at the June 30th regular meeting was the number of homes that had backflow prevention [ype devices and their effectiveness. Attached is a map and listing of addresses (figure 2) that we have on record for installed backwater devices, when the City offered assistance with their installation in the 1970's. One of the main issues with backwater valves is that they r~:axt periodic checking, cleaning and maintenance. Lack of maintenance greatly diminishes their effectiveness. The following COUNCIL ACTION: CITY COUNCIL LETTER Meeting of: 2/17/04 AGENDA SECTION: WORK SESSION ORIGINATING DEPARTMENT: CITY MANAGER NO: PUBLIC WORKS ITEM: Flood Mitigation Measures for Sanitary Sewer BY: K. Hansen BY: Backups DATE: 2/10/04 DATE: represents a list of specific items for consideration by the City Council to address sanitary sewer backups on a short and long-term basis. Potential Mitigation Measures: Short Term Backwater Valves: Consider installing one of two types of backwater valves in affected homes. a. The first is a new type of backwater valve made by Mainline; a diagram of this type of valve is attached. A complete model will be available at the work session. The advantage of this type of valve is they are relatively inexpensive. In discussion with local plumbers, it was estimated that this type of valve could be installed complete for about $1,000, depending on the complexity of the installation. Most plumbers we spoke with suggested adding a gate valve in line, which would add approximately $250 - $300 to the overall cost. b. A second type of valve is a combination shear gate & swing check backwater valve. A diagram of this type of combination valve is attached. This unit has both a swing-check valve and mechanical gate valve within a single housing. This type ofumt has a positive shut offwith a mechanical gate valve shut-off, but is much more expensive. The Public Works Superintendent has put together a listing of pros and cons for this type of installation, attached. The estimated cost for a single valve is $1,293, plus installation. Depending on access and the degree of difficulty, these could be installed for about $2,000 - 3,000 each. A policy could be established by the City of Columbia Heights for assistance irt installation for the full, partial or up to a maximum amount Ibr backwater valves. 2. Water Sensors: Consider installing water sensors in the basements of affected homes. a. Mainline Level Alarm Device: A float style controlled device that activates an alarm when the sanitary flow level in a manhole rises above a pre-determined elevation was installed adjacent to Jackson Pond in 2003. This device was installed with an audible and visual alarm device, and operates on a solar power with battery backup. It is also set up to be compatible with a new SCADA System for direct notification to Public Works. b. Individual Water Alarm Detector: water alert sen~r could be installed in the basements of homes that senses the presence of water, and is not affected by humidity or submergence. A brochure is attached providing details on one such detection system. Battery operated versions mn approximately $325, each. A policy could be established by the City of Columbia Heights tbr assistance in installation for the full, partial or up to a maximum amount for Individual Water Alarm Detectors. Potential Mitigation Measures: Long Term COIINCIL ACTION: CITY COUNCIL LETTER Meeting of: 2/17/04 AGENDA SECTION: WORK SESSION ORIGINATING DEPARTMENT: CITY MANAGER NO: PUBLIC WORKS ITEM: Flood Mitigation Measures for Sanitary Sewer BY: K. Hansen BY: Backups DATE: 2/10/04 DATE: Continue Inflow Reduction Measures: Continue to make system improvements as the Street Rehabilitation work progresses. This includes replacing manhole lids/casting, installing boots on manholes in street low points (brochure attached), manhole repairs or replacements, and lining of sewer pipe. Stall' wilt continue this activiB: in each of the Street Rehabilitation Street Zone areas. Expand Sewer Lining Program: Over the last several years, $50,000 has been budgeted annually for sanitary sewer lining. Staff' recommends considering expanding the program to $75,000 or $100,000, annually, for the next five years. The funding level for this program can then be evaluated and amended annually, if necessary. Staff will prepare an annual sanitary sewer lining program with estimated costs in the $75.000 to $100,000, beginning in 200& Develop an Illicit Discharge Elimination Program: An Illicit Discharge Elimination Program would be the most involved of any of the remediation measures, and could also be the most expensive. The ultimate goal of this program would be to systematically eliminate to the public sanitary sewer system sources of illicit connections from private sources, such as sump pumps, foundation drams and leaking service lines. All of the physical remediation measures identified to date involve reducing or eliminating I/I in the public system. The MCES and the Rural Water Association have estimated that Vi in the private domain can account for up to 60 or 70 percent of the total I/I in a municipal system. A recently completed sump pump disconnect program (Waseca) found that nearly 70% of the remaining Vi was from privately generated sources. The following steps outline an approach to develop and implement such a program: a. Ordinance Development b. Public Education c. Public Informational Meetings d. Advertising Campaign e. Training of City Staff, Local Plumbers, and Contractors f. Site Inspections, Disconnections, and Reinspections g. Enforcement h. Other (potentially smoke and dye testing of non-residential properties) Staff requests direction on whether to proceed with ordinance preparation of an I/I Program, supported by staff and vendor training an active inspection program. An important consideration of a requh'ed disconnection program is a cost-sharing program by the City. Disconnection costs can range from several hundred to several thousand dollars, per household. C'OU~NCIL ACTION: CITY COUNCIL LETTER Meeting of: 2/17/04 AGENDA SECTION: WORK SESSION ORIGINATING DEPARTMENT: CITY MANAGER NO: PUBLIC WORKS ITEM: Flood Mitigation Measures for Sanitary Sewer BY: K Hansen BY: Backups DATE: 2/10/04 DATE: Clean up Assistance Policy: Staff'is currently putting together a policy addressing assistance during instances of sanitary sewer backups into private property. To provide some background, the following is a listing of the number of backups, both public and private, that we have responded to over the last 4 years: Public Private 2003 31 37 2002 30 46 20OI 13 29 2000 14 36 l'he City of Columbia Heights averages 22 backups on an annual basis. Staffis proposing a policy addressing assistance with the initial c ~k:anup after a backup would allow a contracted cleaning service to respond to individual properties with professional services, assislance and advice. Professional firms are trained in this type of cleanup and have hygienists on staff'that can answer and provide more detail on resident questions. The policy provides for a dollar cap recommended $500, $750, or $1,000 (typical homeowner's policy deductible) per property. The City of Columbia Heights has not cleaned basements that had experienced sanitary sewer backups since the early 1990's. Since then, the city has limited it's assistance to offering cleaning solution and aerosol spray disinfectant to residents that have had sanitary sewer backups. We have also contacted the League of Minnesota Cities and they are unaware of any city that currently provides staff for cleanup assistance. I strongly recommend against involving Public Works staff'for Isability, legal and safety reasons. A few examples of Public Works concerns are as follows: · Exposes employees to allegations of theft and or property damage. · Pending Federal Legislation would classify sanitary sewer backup into building as a hazardous spill. Public Works crews are not trained in hazardous materials clean up procedures. · Exposes employees to unknown hazards - (type of materials already stored in a basement.) · Exposes employees to heavy lifting that may cause injury. Example: wet carpet and rugs. · Increases overtime. · Residents may be lulled into a false sense of security if the Public Works crews assist with initial clean up. Some residents would not follow the necessary procedures to complete the clean up, feeling sure that the city had completed all of the necessary clean up. · Legally, the City may not have the right to work on private property without the property owners written permission. · Where do you draw the line for when crews are done, recognizing the variations in severity of backups and how basements are £mished and where/how storage may be located? COUNCIL ACTION: CITY COUNCIL LETTER Meeting of: 2/17/04 AGENDA SECTION: WORK SESSION ORIGINATING DEPARTMENT: CITY MANAGER NO: PUBLIC WORKS ITEM: Flood Mitigation Measures for Sanitary Sewer BY: K. Hansen BY: Backups DATE: 2/10/04 DATE: Our employee's response to questions may result in other implications. The definition of clean up assistance is very. broad, where do you draw the line? o Supply disinfectant and instruction. o Damp mop and squeegee hard surface floor, wet vacuum carpeting o Move everything out of the basement o Remove carpeting, paneling and sheet rock o Steam clean the basement o Separate the water damaged personal items from those that weren't damaged. o Bag and dispose of all garbage o Sanitize the basement. o Cert~' that the basement has been properly cleaned and sanitized. Note: Keep in mind that some basements are unfinished and others have been elaborately decorated. Unfortunately there are also for h~k ora better term garbage houses, where there are so many items stored in the basement that there is barely enough room to walk from one end of the basement to the other. Staff requests input and direction Ibr a proposed policy for the City providing monetary assistance in sanitary, sewer backups tbr the thll, partial or up to a maxflnum amount tbr Proibssional Contracted Clem~ing Sen, ices. Rt, eommended Action: The items highlighted in red throughout this report are items staff is proposing to continue or is requesting direction or input from the City Council.

A SAFEGUARD AGAINST WATER DAMAGE "~',"~=" Anyone who has ever experienced flooding caused by a reversal 0f sewage flow neve?'wants to be confronted with a reoccurrence.

Backwater and it~'a~t~ndant problems must therefore be seriously considered in term of adequate control and prevention by individuals responsible for the design and construction of buildings.

Cost of valve - between $1,000 and $2,000 depending On the type of valve. 2. Cost of installation - $1,000 plus - depends on the location of the pipe and whether'the basement is finished or not. 3. Valve is installed in the basement floor, depending on the depth of the pipe in relation to the floor, the valve handle may be above floor level when the project is competed. ( possible tripping hazard ) 4. Flap valve needs regular maintenance. If any debris gets stuck in the valve, the valve will not close. Flap valve hinge needs to be exercised regularly to keep it from sticking. (note: sanitary sewer valve maintenance is not on the top 10 list for things you always wanted to do.) 5. Gate valve needs regular maintenance to insure that the valve will operate when it is needed. 6. Ball valve works well as a shut off, but the valve may be difficult to open and close. Senior citizens may not be able to operate the valve. 7. To install a backwater valve, a hole is cut in the basement floor. If water table is high in the area and we have a substantial amount of rain, clear water may enter the basement through the hole in the floor. 8. If the property changes, ownership, or if it doesn't rain hard for several years, etc. etc. the resident may forget that they have a backwater valve. 9. Someone has to be home to operate the valve during the heavy rains. 10. If the drain tile was connected directly to the sanitary sewer line and the sanitary sewer line was constructed of vitrified clay tile pipe with joints every three feet, water may exit joints that are no longer water tight and enter the basement through the hole that was cut to install the backwater valve. 1 1. Installation of a backwater valve may adversely affect the resale value of the home. ( Red Flag! problems with sanitary sewer backups) Pro: 1. Backwater valves may limit the amount of sewage that backs up into a basement under the right circumstances. 2. Public Relations ? If the valve is installed and the property owner still experiences backups durir~g heavy rains, did we help or hurt the situation. ( False sense of security.)
