PROJECT SUMMARY Public Works The 2012 project includes the reconstruction of 7901 Park Place approximately 1.1 miles of streets in the Phone: 952.227.1300 Minnewashta Heights neighborhood. The street Fax: 952.227.1310 segments within the proposed project were Senior Center identified by the City's Pavement Management Phone: 952.227.1125 software, site investigations and utility Fax: 952.227.1110 problems in the area. Web Site The streets in Minnewashta Heights are 40 www.ci.chanhassen.mn.us years old and cannot be cost effectively repaired with minor maintenance such as sealcoats or even a bituminous overlay. These streets were last sealcoated in 1994 and 1999. Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow Minnewashta Heights Improvement Project Assessment Hearing April 23, 2012 Page 2 The streets are in poor condition with an average pavement condition index of 38. A road under 45 typically indicates distress that would require a full -depth reconstruction. The west portion of Shore Drive has a pavement condition index between 52 and 64; however, these scores are artificially high since there are three watermain break patches in this vicinity and this area has been patched extensively. The plat for the area shows the roadway right -of -way is 50 feet wide. The width of the roadways varies from 24 feet to 28 feet wide. The existing road section is bituminous pavement with no curb and gutter. No sidewalk is in the project area and no new sidewalk is proposed to be included with the project. The proposed improvement calls for reconstruction of the roadway. The width of the roadway is proposed to be about the same width of the existing streets. Concrete gutter is proposed to be added to this area to improve drainage and help extend the life of the streets. The proposed design includes a modified street section that reduces the amount of sand from 24" to 18" and the amount of Class 5 from 12" to 8 ". These revisions were recommended by the City's soils engineer, Braun Intertec, to provide the same structural strength as the standard street section based on known subsoil conditions. Some trees within the right -of -way in front of some residential lots will be impacted by the reconstruction work. The plans include the removal of approximately 45 trees within the project area due to water service and hydrant replacement. Staff will work with affected property owners to minimize the tree removal as much as possible. Sanitary Sewer Improvements Staff has investigated and televised the condition of the sanitary sewer in this area. Approximately 1,600 feet of sewer is proposed to be replaced due to the condition of the pipe. No sanitary sewer backup problems have been recorded in this area; however, a number of pipe sags have been identified and these areas should be replaced at this time. The sanitary sewer services that access these sections of the pipes are also proposed to be replaced between the lateral sewer and the right -of -way. Sanitary sewer pipe replacement will be by the traditional open cut method. The sewer that will be replaced is between 10 and 22 feet deep. The remaining sewer pipe is in good structural condition, although some require mineral removal, grouting and /or lining to reduce the incidence of inflow and infiltration. These minor repair areas are also proposed to be fixed at this time. This work can be done without digging up the pipe. Watermain Improvements The watermain in this area is 40 years old and should be replaced at this time. The mains are made of cast iron and 11 documented breaks have been recorded in this area, the most recent being on March 25, 2012. Water services between the lateral watermain and the right -of -way are proposed to be replaced, as well as the curb stop. The new watermain is proposed to be eight inch diameter PVC pipe. Minnewashta Heights Improvement Project Assessment Hearing April 23, 2012 Page 3 The bid included alternates for open cut and directional drill installation of the new watermain. The directional drill technology requires excavations at each end of the installation, which minimizes the disruption to the ground surface. Open cut trenches are still required to install the new water services and curb stops. The bid price for directional drilling ranged from $100,000 to $260,000 more than the open cut method, with the exception of one bid. The GM Contracting, Inc. bid for directional drilling was about $5,000 cheaper than open cut, however, their bid prices for the street, sanitary sewer and storm sewer were $675,000 higher than the low bidder, Northwest Asphalt, Inc. Staff is recommending awarding the contract with the open cut method. Storm Sewer Improvements The Minnewashta Heights plat area is approximately 56 acres in size and the actual watershed within the project area is 32 acres. Currently there is very little stormwater infrastructure or piping system in the area. The majority of the stormwater runoff generated by this neighborhood discharges directly into Lake Minnewashta. The area is fully developed so construction of new stormwater treatment ponds to treat runoff before it discharges into Lake Minnewashta is not an option. Runoff from Maplewood Court will be piped to the existing stormwater ponds off of Landings Drive, west of the project area. The runoff from the Highway 7 right -of -way will no longer be conveyed to this pond to provide capacity for the drainage from Maplewood Court, A MnDOT drainage permit application has been approved. G:\ENG\PUBLIC\ PROJECTS \12 -01 Minnewashta Hts recon \04 -23 -2012 assessment hmg.docx Minnewashta Heights Improvement Project Assessment Hearing April 23, 2012 Page 4 The northern part of Elm Tree and the majority of Dogwood Avenue will continue to drain to Minnewashta Heights Park. There is an existing drainageway on the south side of the park within the treeline. Three filtration basins will be constructed in the park to provide rate control of the runoff. The filtration basin locations were chosen to minimize tree loss; three ash trees are proposed to be removed. The filtration basins will be two to three feet Y IS' 2° en 1 -� y ' deep and will be planted with shrubs so that landscape maintenance will not be required. An Iron - Enhanced Sand Filtration system is an underground treatment system that captures suspended solids, particulate phosphorus, and dissolved phosphorus. The iron forms rust (iron oxide) and the dissolved phosphorus attaches to these iron oxides, thereby removing it from the stormwater runoff. The iron filtration system is designed to treat the first 1/2 to 1 inch of a rain event. Any excess runoff will bypass the iron filing system, into the storm sewer discharge to Lake Minnewashta. This system is also known as the Minnesota Filter because it was developed at the St. Anthony Falls Laboratory at the University of Minnesota. Several communities such as St. Louis Park and Prior Lake and watershed districts have used this system successfully for stormwater treatment where standard treatment ponds are not an option. Rain gardens (biofiltration areas) are stormwater management practices intended to mimic natural conditions. They treat runoff from smaller drainage areas and promote infiltration, which reduces the volume of water getting to Lake Minnewashta and removes the nutrient load associated with the infiltrated volume. These areas may be planted with a variety of plants ranging from prairie species to a perennial garden to shrubs and mulch. G:\ENG\PUBLIC\ PROJECTS \12 -01 Minnewashta Hts recon \04 -23 -2012 assessment hmg.docx Minnewashta Heights Improvement Project Assessment Hearing April 23, 2012 Page 5 Rain gardens have been installed on homeowner properties along Pontiac Circle and Foxford Road and in Lake Ann Park. There are no specific areas within the proposed project area where rain gardens would be required. Participation in the rain garden program is voluntary. The rain garden option was presented at both neighborhood meetings and in January, 2012 a letter was sent to owners whose properties drain toward the lake reminding homeowners about the option to have a rain garden installed. The bids included the construction of five rain gardens based on resident interest at the time. After the project was out for bid, additional residents expressed an interest in having a rain garden installed on their property. Funding for additional rain gardens will be from the SWMP -035 LID Implementation Project fund. The plans include the installation of St. Anthony Falls Laboratory Baffles (SAFL Baffles) in four of the sump storm manholes. The intent of sump manholes is to provide an area within the storm manhole for solids to settle and limit sediment deltas at storm pond inlets, however during heavy rain events, the volume and velocity of runoff through the manhole resuspends the solids. The resuspended sediment is then conveyed to the inlets of downstream water features which decreases the capacity of ponds and requires maintenance in that the sediment must be removed. The SAFL Baffles are designed to prevent runoff from becoming turbulent in the sump manhole, thereby reducing the resuspension of solids. ASSESSMENT HEARING PROCEDURE Staff will provide a brief explanation of the work along with the proposed assessment amount. Any issues that the City Council wishes to discuss regarding the project financing is appropriate during the public hearing portion of the project. Public testimony should be received for the project. The property owners should be reminded that if they wish, they must file a written objection with the city either prior to or during the actual project hearings. Objections after the public hearing are invalid. The assessment objection is a request by the property owner for the Council to review the assessment amount. Staff may have an immediate response to individual comments, or in some circumstances, the objection should be received and referred to staff for investigation. The remaining assessment roll should be adopted. If the City Council feels the objections cannot be addressed immediately, a report will be presented to Council regarding all objections on that particular project at the next City Council meeting. Council should adopt the remaining assessment roll at that time in order for the process to stay on schedule. If there are no objections filed, or if Council feels confident staff's investigation will not result in any changes being made to the assessment roll, a motion by the City Council adopting the assessment roll as prepared is needed for the project. ASSESSMENT OBJECTIONS Objections may be filed up to and at the public hearing. At the time of this submittal, no written objections have been received. If any written objections are received in the interim prior to the Council meeting, they will be provided to the council at the public hearing. Staff comments and recommendations will also be provided at the public hearing. The City Council may choose to adopt staff's recommendation or revise the assessment roll. If additional objections are filed G:\ENG\PUBLIC \_2012 PROJECTS \12 -01 Minnewashta Hts recon \04 -23 -2012 assessment hmg.docx Minnewashta Heights Improvement Project Assessment Hearing April 23, 2012 Page 6 either prior to or at the hearing, they should be received and if necessary referred to staff for investigation and resolution. PROJECT SUMMARY: ASSESSABLE COSTS Improvements within the project include reconstruction of the street, the replacement of sanitary sewer and watermain, and storm sewer improvements. Forty percent (40 %) of the street improvement costs are proposed to be assessed against the benefitting properties. PROJECT COSTS AND ASSESSMENTS Per the city assessment practice, forty percent (40 %) of the street costs are proposed to be assessed to the benefiting property owners; the City will be responsible for the remaining 60 %. One hundred percent (100 %) of the utility costs will be paid for by the respective enterprise funds. Bid Amount Street Improvements $1,246,097.00 Watermain Improvements $398,486.67 Sanitary Sewer Improvements $209,736.92 Storm Sewer Improvements $384,536.56 $2,238,857.15 The total project cost has been calculated to be $2,562,222.85 which includes a 3% construction contingency and indirect costs such as survey costs, soils testing, engineering costs, construction observation, etc. The assessments were calculated as follows: Total street reconstruction cost $1,246,097.00 Construction Contingency $37,382.91 Indirect costs $75,712.20 Total Street Cost $1,359,192.11 40% assessed $543,676.85 $543,676.85 _ 91 assessable units = $5,974.47/unit Terms for the assessments proposed are at equal annual installments over ten (10) years at an interest rate of 5.25 %. The estimated unit assessment identified in the feasibility report was $6,952.53. By reducing the pavement section, the estimated assessment was reduced to $6,025.26. The final unit assessment amount is $50.79 lower than the engineer's estimate for the revised pavement section.
