CR 95-159 Public Hearing, 1996-200 Capital Improvement Plan• September 1, 1995 n a PUBLIC HEARING, 1996 -2000 CAPITAL IMPROVEMENT PLAN Proposed Action Staff recommends no action on this item at this time. Council Report 95 -159 The purpose of this meeting is to review the Capital Improvement Plan and to accept public comments during the public hearing process. Overview The Capital Improvement Plan is a financial and physical planning tool utilized by the City since 1987. The purpose of the CIP is to discuss and organize future years major projects and to analyze the available revenue sources necessary to accomplish those projects. The CIP is intended to be flexible in timing of the projects and does not require completion of the projects in the specified years of the plan. Projects require additional approvals during the budget process as well as individual approvals as the projects move forward. Thus, the CIP is truly a planning tool from which projects are scheduled for completion in future years. Primary Issues to Consider o Does the CIP adequately address the needs of the City? The Capital Improvement Plan has been formulated with the input of the staff, Park Board, Planning Commission and City Council. While no tool is all encompassing, it thoroughly represents the anticipated projects and needs of the community. o What process will be used for final adoption of the plan? Along with the proposed expenditures will be the proposed revenues. The revenues available for projects will be estimated and matched against the proposed projects. Should revenues be unavailable, projects would need to be prioritized and scheduled according to the revenues available. It is anticipated that the City Council will adopt the CIP at its first regular meeting in October. Public comment is encouraged during the month of September to complete the input process toward completion of the CIP.

The Design Committee first met on May 24 to discuss the redevelopment concept plan which was developed by the Joint Recreation Board in conjunction with Brauer and Associates, Ltd., the consultant selected to develop a master plan. A second meeting was conducted on July 18 to review architectural plans which were developed by the consultant. included in the plans were the Committee's recommendations for family changing areas and increased storage. Subsequent the Committee's approval of the architectural plans, the redevelopment concept plan was presented to Shady Oak Beach area residents at an August 11 neighborhood meeting. Although a number of neighborhood residents expressed concern regarding current boat access and water quality issues, comments regarding the redevelopment project were generally positive. The purpose for discussion at the September 5, 1995 Council meeting is to review a number of issues pertaining to the potential redevelopment of the beach. Items for Council discussion include the following: Plan Review The Council is asked to review the prepared architectural plans and provide any comments to the Design Committee. Outlot "B" The City of Minnetonka, as part of its Loop Trail System, has scheduled completion of the bridge linking the peninsula for November 15, 1995. Neighborhood residents have expressed a desire that current parking available at outlot "B" be eliminated in conjunction with the bridge opening. The redevelopment concept plan includes a children's play area at the site. • Financing • Review of Shady Oak Beach Redevelopment Process August 22, 1995 Page 2 This request presents the following questions /options: 1. Will the City of Hopkins allow the current parking to be eliminated? If so, construction of a play lot, paid for by Minnetonka, would be completed in the spring of 1996 and be separated from the beach redesign project. 2. Is the City of Hopkins interested in transferring ownership of outlot "B" to the City of Minnetonka? If so, could this transaction be used to support part of Hopkins commitment to the redevelopment project. 3. Last winter, Hopkins Public Works maintained access to the beach parking area which allowed users of the lake to park in the beach parking lot. This option lessened the demand for parking at outlot "B ". Does the provision of parking and boat /canoe access at the beach site satisfy the Councils need for parking at outlot "B "? Minnetonka Council member Dick Allendorf, indicated to the Design Committee a desire to have Minnetonka fund the redevelopment project, with reimbursement from Hopkins over an agreed upon time period, if phasing of the project was not financially beneficial. Jeff Schoenbauer of Brauer and Associates, Ltd. has estimated that phasing the project will require an additional $1 17,000 to complete. Costs contributed to inflation at 5.5% estimated to be $91,000. Based on an estimated $1 .6 million budget which does not include costs associated with phasing, the cities of Minnetonka and Hopkins have included the following amounts in their Capital Improvement Programs: 1996 1997 1998 1999 2000 Minnetonka 500,000 600,000 - - - Hopkins 100,000 100,000 100,000 100,000 100,000 (proposed) Maintenance Concerns There are three maintenance concerns related to the operation of the beach that will need to be addressed regardless of whether the beach redevelopment project is approved. • • • Review of Shady Oak Beach Redevelopment Process August 22, 1995 Page 3 I. Replacement of Deep Water Docks The existing condition of the deep water docks requires their replacement prior to the 1996 season. Prior to the 1993 swimming season, a portion of the east dock was removed because it was deemed unsafe. The estimated cost for replacement of the docks is $50,000 - $75,000. 11. Sanitary Sewer Staff recommends that replacement of the current septic system be considered. Last February, the consulting firm of Short, Elliot, Hendrickson, Inc. (SEH) performed a study to determine various options for replacement of the current system. Their recommendation, which would connect the beach facilities to service on Dominick Drive, could be completed for $47,500. 111. A.D.A. Compliance At the request of the Joint Recreation Board, Brauer and Associates, Ltd. prepared an estimate that determined compliance with the Americans with Disabilities Act (A.D.A.) would require $443,750. Under A.D.A. guidelines, plans providing access for persons with disabilities to public facilities and programs were to be in place by January 26, 1995. Based on this information, Council is asked to provide staff with direction regarding each of the Shady Oak Beach Redevelopment issues outlined in this memorandum. • Shady Oak Beach Redevelopment Study Joint Recreation Board Cost Analysis Supplement for Hopkins and Minnetonka Date November 20, 1994 To Joint Recreation Board Advisory Committee Representing: • City of Hopkins • City of Minnetonka From Project Planning Team Project Manager - Jeff Schoenbauer, RLA,Vice President, Brauer & Associates Overview At the request of staff, the following is a breakdown of potential costs associated with upgrading the existing beach area facilities to meet minimal ADA and code compliance requirements.

SUITE 590, MINNETON■A, MN 55345 612 931-9501 FAX 612 937-1188 ARCHITECTURE • ENGINEERING • ENVIRONMENTAL • TRANSPORTATION RE: Minnetonka, Minnesota Shady Oak Beach Sanitary Sewer Study SEH No: MINNE9503.00 We are pleased to submit the results of our study on the alternative means to provide sanitary sewer service to the proposed Shady Oak Beach Redevelopment Project. As background information, we were provided the following: 1' Section 3 -- Master Plan Cost Analysis from the Shady Oak Beach Redevelopment Study by Brauer and Associates Ltd • Y Feasibility Study for Sewer and Water Service to Shady Oak Beach by Schoell & Madson, Inc. dated May 17, 1982 Contour maps Sanitary sewer as- builts • The study was to address alternative methods of sewer service to the site, their associated costs, and environmental impacts. Of particular concern is the potential impact of routing a sanitary sewer near or under the water level of Shady Oak Lake and the cost associated with that construction. General Discussion There are two locations where sanitary sewer service is reasonably available. One location is in Dominick Drive near the intersection of Jorissen Drive. This would require a crossing of Shady Oak Lake in the old railroad grade. The other location is in Beachside Drive which serves the townhouse development east of Shady Oak Road and south of the Soo Line Railroad. The sewer in Beachside Drive is only about 1000 feet frorn the buildings clustered at Shady Oak Beach. However, gaining access to that sanitary sewer includes crossing several hills, railroad tracks, Shady Oak Road, and a parking area in the townhouse development before reaching the sanitary sewer in Beachside Drive. Crossing of the railroad tracks and Shady Oak Road would require additional permits, engineering costs, and construction costs. Crossing the parking lots of the townhouse development would require easements and driveway and sod restoration. Even though new trenchless construction methods are available for the crossing of the railroad tracks and Shady Oak Road, the extra expense, complexity of the design and construction, and lack of actual ownership of the sewer alignment are all detrimental to this connection location. It would be our recommendation that this connection location be considered only if all other methods of crossing Shady Oak Lake in the old railroad grade are rejected. Although it is possible to connect to the trunk sewer in Dominick Drive with a gravity sewer extension to the Shady SHORT ELLIOTT HENDRICKSON INC. ST PAUL. MN ST CLOUD, MN CHIPPEWA FALLS WI MADISON Wr Mr. Dave Johnson February 14, 1995 Page 2 • • Oak Beach site, it is not a practical alternative. Excessive dewatering would be necessary along with tree removal along the old railroad grade. The initial cost would exceed the cost of a pumped alternative. Even considering long- term operation and maintenance costs of a pumping station, a pumped alternative is, in our opinion, the most cost - effective alternative. In addition to the cost factor, the gravity sewer alternative could be highly detrimental from an environmental standpoint. The Shady Oak Beach Redevelopment Project is still in the conceptual stage. Accordingly, the amount of sewage to be generated at the site is still largely unknown. However, preliminary designs of pumping stations which could serve the site indicate that with a nominal 1V? forcemain, pumping rates of over 25 gallons per minute are easily achieved with some of the smallest pumps available. This should be adequate for any reasonable application at this site. The forcemain alignment for Options 1 through 3 which follow is shown on the attached drawing. The lift station would be located near the existing/proposed buildings. It would pump westerly down the old railroad grade across Shady Oak Lake to an existing manhole of the trunk sewer in Dominick Drive. For purposes of this study, it was assumed that the forcemain project would incur no restoration costs except the cost of crossing the existing parking lot and Dominick Drive. It is anticipated that a more formalized trail would be constructed along the forcemain alignment concurrent with or after the forcemain is constructed. Option 1 This option would consist of constructing a small "grinder pump" lift station on the Shady Oak Beach site. A control panel with local alarm would be installed in one of the buildings occupied by staff. The lift station would pump westerly through a 1 V2 forcemain to a discharge manhole constructed approximately at the east end of the parking lot at Dominick Drive. Sewage would then flow by gravity through a 6 -inch sewer service to the trunk sewer in Dominick Drive. The forcemain would be constructed at approximately a four -foot depth by use of a ditching machine or a vibratory plow. Either alternative only leaves a scar at the surface with little disturbance of soil horizons. In fact, at a four -foot depth the forcemain would be at or above the normal lake levels of Shady Oak Lake except for the channel crossing. Vegetation loss would be minimal. At the channel crossing, the forcemain would be trenched or plowed below the channel bottom, but yet in the old railroad fill above the lake bottom. The natural lake bottom that existed prior to the railroad fill would not be pierced. No dewatering would be necessary. The equipment used for this kind of installation could easily travel through a couple feet of water at the channel location. Sediment control would need to be carefully designed for the channel crossing. The type of forcemain proposed comes in large rolls and would be field fused so as to be one continuous length of pipe, thereby making leakage from the forcemain almost impossible. However, due to its shallow depth, future construction in the area could damage the pipe. To minimize the possibility of damage by future construction activities, a trace wire would be installed in the trench with the forcemain to aid in locating the forcemain for any contractor working in the area. This system, being too shallow to provide frost protection, would not normally be useable in the winter. We understand that there are currently no plans for the beach area which would require sewage service in the winter. However, should the need arise, such as for a trailhead or skating facility, there is a way to make this alternative useable in the winter. This would be accomplished by using a larger than normal wet well at the pumping station. With the very limited flows likely in the winter, the wet well could function as a holding tank. Sewage would need to be hauled periodically during the winter, perhaps as seldom as once a season at very nominal cost. Mr. Dave Johnson • February 14, 1995 Page 3 Option 3 Similar to Option 1, a grinder pump lift station would be constructed with a 1W forcemain discharging to the sewer at Dominick Drive. To provide frost protection and potential year -round use, the forcemain would be installed at a seven -foot depth. The wet well for the lift station could be of normal size since it would not need to function as a holding tank in the winter. The trace wire would not be necessary. Even at a seven -foot depth, the forcemain would not be below the lake bottom, again avoiding the potential of piercing the bottom of Shady Oak Lake. Option 4 This option would consist of constructing the conventional lift station contemplated in the May 17, 1982, Feasibility Study for Sewer and Water Service to Shady Oak Beach by Schoell & Madson, Inc. This type of lift station included larger duplex pumps with a remote alarm system and all other amenities similar to the City's other lift stations serving multiple properties. We have not reexamined this option, other than to update its cost based on the Engineering News Record Construction Cost Index. Based on this index for May of 1982 and the current index, the cost estimate should be increased by approximately 54%, which would result in an estimated total project cost of about $79,000. No other review of this option was made. • The operation and maintenance impacts of this option are also minimal. Each fall, it would be appropriate to pressure test the forcemain to verify its continued leak -proof status, flush the main, and blow all liquids out of it so the main does not freeze and break. The large wet well should be pumped dry in the fall to remove any sand and other sediment which may have been deposited in it from the swimmers using the showers and restroom facilities. Option 2 This option is very similar to Option 1 except that the channel crossing would be accomplished by suspending the forcemain from the bottom of a bridge. We understand that a bridge is being contemplated for the channel crossing to complete the Loop Trail system. Suspending the l' /! forcemain from the bottom of the bridge avoids the need for an under water channel crossing and its associated sediment control. However, an air relief valve will be necessary at this location potentially resulting in odors discernable by trail users. The system becomes more complex with additional fittings, valving, and the need to protect the exposed pipe. This option, of course, requires that the bridge be built concurrently with the forcemain. Option Comparison The table attached to this report provides a quick comparison between the various options described. It can be seen that the costs of Options 1, 2, and 3 are all very similar. Accordingly, the option best serving the needs of the City should be chosen. If none of these options are deemed appropriate, then a connection to Beachside Drive should be further studied. Recommendation We would recommend that the City consider Option 1 for the following reasons: 1. Its cost is similar to the other two least expensive options. 2. Environmental damage during construction will be minimal or nonexistent with the proper sediment control system. 3. There is little risk of leakage from the type of forcemain proposed, particularly if occasionally pressure tested to verify integrity. 4. This option does provide a means of serving the site in the winter should winter uses of the facility become attractive.
