Il. PROJECT LOCATION The roadway portion of the project is located within Sections 20, 21, and 22, Township 121 N, Range 23W, in Otsego, Minnesota. The project area and roadway location is depicted on Exhibit A at the back of this report. III. ROADWAY IMPROVEMENT PROJECT A. Existing Conditions The project consists of improving 85th Street from Page Avenue to approximately 650 feet east of Odean Avenue, then from approximately 500 feet west of Odean Avenue to approximately 700 feet east of Nashua Avenue. The project termini are the extents of previous MSA projects which improved 85th Street to MSA Standards. 85th Street is a 24 foot wide paved rural design street with ditch sections and culverts to provide drainage. The existing shoulders consist of 0.5' to 2' of topsoil in some areas, and are non-existent in others. Odean Avenue traverses 85th Street, separating it into east and west segments. The west segment is located between Nashua Avenue and Odean Avenue and is designated as MSA route 217-102-015. The east segment is located between Page Avenue and Odean Avenue and designated as MSA route 217-102-020. The west segment is approximately 4,410 lineal feet. The east segment is approximately 3,655 lineal feet. Both segments of roadway have exhibited signs of pavement distress in recent years. The western segment has required patching in recent years to replace areas of severe alligator cracking. The alligator cracking is caused by structural failure of the roadway section, and may be attributable to the poor subgrade materials. Page 1 \\Ha01\Shared DocsWuniapal\AOTSEGO\332\0T332Revised FEAS.doc The soils in the project area appear to vary from fine sands, to sandy foams, to loams. Inclusions of silty clay loams were noted in the section of 85th Street between Nashua Avenue and Odean Avenue and at the intersection of Odean Avenue and 85th Street. The subgrade soils are thought to be generally unsuitable for roadway construction. Test borings must be performed during the design phase of the project to determine the exact subsoil characteristics. The National Wetland Inventory (NWI) Maps indicate that some of the low areas within the existing right-of-way may be Wetland Conservation Act of 1991 (WCA) wetlands. These areas may require special attention during the project design phase. The wetland areas must be delineated and work must be performed within the guidelines of the WCA. The existing ROW is 66 feet along the length of the roadway. There are no known drainage and utility easements located adjacent to the ROW. The roadway profile exhibits sharp vertical curves, reducing site distances in some areas. Site distance is also limited at several roadway intersections along the project length due to horizontal obstructions, primarily tree growth. The average daily traffic along the roadway is expected to increase in the near future due to proposed development work. An executive style golf course has recently opened in the NW '/4 of the SE '/4 of Section 20. Heritage Hills is continuing to add homes in the NW '/4 of the SW '/4 of Section 21. Crimson Ponds will add an access onto 85`x' Street. All of these developments, when completed, will cause an increase in traffic to 85th Street, and may burden the capacity of the roadway as it exists. 85`h Street at the intersection of Odean Avenue, has been improved to MSA standards and will reduce the cost for 85th Street improvements and lessen the amount of traffic disruption the reconstruction of 85th Street will cause. Also, major trunk stormwater improvements have been completed reducing 85th Street costs. These improvements include the regional pond in Heritage Hills, the regional pond on Wilson-Berge's property south of Hall's Pond, and storm sewer with the capacity to handle the runoff from ultimate development of the Hall's Pond watershed. B. Proposed Improvements The project involves constructing the roadway to Municipal State Aid (MSA) Standards. 85th Street is proposed to be a 44 foot wide urban design section with concrete curb and gutter. A 10' bike -path on the south side of the road is included in the proposed typical section. Page 2 \\Ha01\Shared Docs\Municipal\AOTSEGO\332\OT332RevisedFEAS.doc The typical design section will consist of a minimum 4'/z" bituminous surface over a minimum of 7" of Class 5 aggregate base course (identical to Odean Avenue). A 2' layer of clean sand will be placed below the aggregate base to provide structural support where subgrade soils are determined to be inadequate for roadway construction. Exhibit B depicts a typical MSA urban design section with bike path. Right-of-way purchase will be required to expand the ROW from 66' to 80'. Slope easements and temporary construction easements will be required to allow for roadway construction. The extents of the ROW and easements required will be determined during the preliminary design phase of the project. ROW acquisition will occur during the final design phase of the project. ROW acquisition must be initiated soon to insure that construction can begin in 2001. C. Estimated Costs Costs for street construction were analyzed for each segment of the proposed 85th Street. Our cost estimates are as follows: Table I 85th Street Odean Avenue to Nashua Avenue MSA Segment 217-102-015 Cost Estimate Item Common Excavation and Subgrade Prep Class 5 Aggregate Base Course Bituminous Surfacing Concrete Curb and Gutter Erosion Control & Revegetation Storm Sewer Total Estimated Construction Cost Construction Contingency at 10% ROW Acquisition Overhead at 20% TOTAL ESTIMATED PROJECT COST Page 3 \\Ha011Shared Docs\Municipal\AOTSEG0133210T332Revised FEAS.doc Estimated Cost $160,000 78,000 158,000 78,500 13,000 126,000 $613,500 61,350 44,250 122,700 $841,800 Table II 85th Street Page Avenue to Odean Avenue MSA Segment 217-102-020 Cost Estimate Estimated Item Cost Common Excavation and Subgrade Prep $96,450 Class 5 Aggregate Base Course 61,000 Bituminous Surfacing 131,000 Concrete Curb and Gutter 65,250 Erosion Control & Revegetation 11,350 Storm Sewer 107,000 Total Estimated Construction Cost $472,050 Construction Contingency at 10% 47,205 ROW Acquisition 35,600 Overhead at 20% 94,410 TOTAL ESTIMATED PROJECT COST $649,265 D. Financing and Assessments 1. MSA Account The portion of 85th Street studied is currently on the City of Otsego's MSA system. The MSA segment designations are 217-102-015 (Odean Avenue to Nashua Avenue) and 217-102-020 (Page Avenue to Odean Avenue). The roadway qualifies for MSA funding for construction, ROW acquisition, and engineering services. The City receives MSA allotments annually, 25% of which is allocated for maintenance. The remaining 75% is designated for construction. The 2001 MSA construction allotment was approximately $240,000. MSA allotments are determined based upon population and roadway mileage within the City. The estimated allotment for MSA construction funds in the near future (2 years) is estimated to remain the same. Page 4 \\Ha01\Shared Docs\Municipal\AOTSEGO\332\OT332RevisedFEAS.doc MSA allows City's advancements on funds for construction after all of the existing is used up or encumbered. The lesser of three years allotment or $750,000 can be advanced to Municipalities for construction projects. The maximum the City of Otsego could advance is $720,000. This is approximately 3 years of construction funds. As a result of this advance, the City would not receive future construction allotments until the advancements are paid back (approximately 2004). The advance in funds would not affect the maintenance allotment. 2. Assessment Policy The City of Otsego's Assessment Ordinance sets guidelines for determining assessment amounts for properties which abut MSA designated and eligible streets. The ordinance indicates that abutting properties shall be assessed for the costs of a typical street and any additional costs shall be paid for by the City. The typical roadway section would consist of a 33 foot wide roadway with concrete curb and 5' wide boulevards. Our estimated lineal foot cost for this type of roadway is as follows: Table III City of Otsego Estimated Construction Costs Typical Urban Roadway Section Item Common Excavation and Subgrade Prep Class 5 Aggregate Base Course Bituminous Surfacing with Curb Erosion Control & Revegetation Storm Sewer Signs Total Estimated Construction Cost Overhead and Contingency at 30% Estimated Cost per Lineal Foot $3.25 10.00 20.50 2.50 5.75 0.90 $42.90 12.87 TOTAL ESTIMATED PROJECT COST PER LF $55.77 By dividing the total estimated project cost by two, an assessment value per front foot of property is obtained. The estimated cost per front foot of property was determined to be $27.89.

Projected Roadway Assessments Potential roadway assessments were determined based upon property access to 85th Street. Table IV, V, and VI were generated based upon front footage from half -section maps and costs described in Table IV. The benefiting properties for the roadway construction portion of the project are depicted on Exhibit A. Based upon a front foot cost of $27.89 and a total assessable front footage of 6909 the total potential revenue from street assessments was determined to be $192,692.01 (see Table IV). Table V depicts the proposed assessments for constructing 85th Street from 700' east of Nashua to 1/8 mile west of Odean Avenue & Table VI shows the proposed assessments for construction of 85th Street form 1/8 mile east of Odean Avenue to Page Avenue. Looking back at similar and recent roadway projects that were assessed, the city has lowered the assessment depending upon the situation or the classification of the road. In Odean Avenue's case the actual assessment was approximately 50% of that determined using the assessment policy. The City council's reason for the reduction was because of Odean Avenue's status as a collector street. This may set a precedent for 85th Street's assessment.

STORM SEWER IMPROVEMENT PROJECT The proposed roadway improvements will occur primarily in the Hall's Pond Watershed area. The long range watershed improvements must be considered for the design of the 85th Street improvements. The 85th Street storm sewer will serve as a facility to convey stormwater from the Hall's Watershed to the Hall's Pond area. Exhibit C depicts the Hall's Pond Watershed. We estimate that the trunk and lateral storm sewer for the west portion of the project would be MSA funded at 55% and the east portion of the project would be MSA funded at 100%. MSA funding of storm sewer is determined by the percentage of land being drained from road right of way versus the amount of total land being drained through the proposed storm sewers. V. PROJECTED FUNDING BALANCE The existing Otsego MSA funds available for road construction are assumed to be encumbered due to pending right-of-way on Odean Avenue and 781h Street. Based upon our initial review of the project, we have prepared the following table: Page 7 \\Ha01\Shared Docs\Municipa1\AOTSEGO\332\OT332Revised FEAS.doc V. PROJECT SCHEDULE The schedule for this project will be effected by the date the Council holds a public hearing and orders the preparation of Plans and Specifications. A project schedule will be prepared for the public hearing by our office. VI. CONCLUSIONS AND RECOMMENDATIONS This report analyzed the feasibility of reconstructing 85th Street from Page Avenue to Nashua Avenue to meet Municipal State Aid (MSA) Standards. Stormwater drainage within the Hall's Pond watershed was also reviewed. The 85th Street storm sewer will serve as a trunk facility for that watershed. The improvement is technically feasible as described in this report. The storm sewer system improvements to be made in conjunction with this project include oversizing the 85th Street storm sewer to serve as a trunk facility The storm sewer improvements would be best made in conjunction with the 85th Street reconstruction project. Reconstruction of 85th Street is necessary due to the recent structural deterioration of the existing pavement section. Potential development in the area may tax the capacity of the existing roadway, which makes the improvement desirable. The project would be funded by assessments and by MSA funding. The project appears to be cost-effective if an advancement of MSA construction funds is obtained by the City. The estimated MSA funds available are less than estimate construction cost. The MSA funds available were estimated and may exceed the amount listed. We recommend that this study be forwarded to an appraiser for review of the assessment amounts recommended in this report. The appraiser should determine if the proposed assessment amounts are equivalent to or less than the benefit of the improvement.

February 22, 2001 Mike Robertson City of Otsego 8899 Nashua Avenue NE Otsego, MN 55330 Re: Engineering Manual Dear Mike, 3601 Thurston Avenue, Suite 101, Anoka, MN 55303 Phone: 763/427-5860 Fax: 763/427-0520 The following revisions have been made to the City of Otsego Engineering Manual: Changes Made 1. "Revised 2/27/01 " was added to the cover page. 2. "Rip -rap will also be required at inlet" was eliminated on page 10, 2.c. Wood fiber blanket is now required at all inlets. 3. "Only screw type adjustments are allowed" was added to page 14, 3.c. 4. Page 14, 4. Streets - all bituminous is now to be in accordance with MnDOT 2350 5. Page 14.4 now reads "Concrete curbing MnDOT 2351 using B618, or Otsego Standard Plate 704." 6. Page A-1, Series 1, 106 changed to Urban Mailbox Location. Civil Cr Municipal Engineering Land Surveying, for Ma01\Shared Docs\Mun,cipal\AOTSEGO\920\engmanual.doc Reason For Change This is the date of the most recent revision. Wood fiber blanket will prevent erosion around the inlet before the grass growth is sufficient. This was added to prevent the use of ring type adjustors which are simply glued to the top section. MnDOT has changed its specifications to a performance grade asphalt. MnDOT Curb S512 was shown before, which is a little different than Otsego's standard. Standard Plate 106 is now a urban mailbox location detail. 25 Changes Made 7. Page A-1, Series 2 "207 Curb Box Lid Cover" was added. 8. Page A-1, Series 3 "308 Chimney Seal" was added. 9. Standard Specifications for Street Construction, Page 2, C.c. "compacted within 0.10 feet". 10. Standard Specifications for Street Construction, Page 2, C.d. "compacted and graded within 0.05 feet" rather than "to + 0.10 feet". 11. Standard Specifications for Street Construction, Page 7 widths were revised in Urban Design and Rural Design tables. 12. Standard Plate No. 105. Horizontal measurement now reads 8" to 1'. Vertical measurement now reads 38" to 42". 13. Standard Plate No. 106 was changed from a perforated pipe detail to an urban mailbox detail. 14. Standard Plate No. 108 Back to Back roadway width was revised to 33'. 15. Standard Plate No. 200 A steel post painted blue is now required for a marker. 16. Standard Plate No. 300, 301 Notes have been revised for moisture proofing and added for chimney seals. 17. Standard Plate No. 302, 303 A steel post is now required for a marker. \\Ha01\Shared DocsWunicipaPAOTSEGO\920\engmanual. doc Reason For Change A detail for curb box lid covers was added for curb stops in driveways. Chimney Seals help prevent water infiltration at the surface and help prevent loss of road material. Wording was changed from "compacted to ± 0.10 feet". Closer tolerance is now required, wording was changed. All widths are now correct and are in asccordance with Otsego standard plates. The measurements are now in accordance with the US Postal Service. The perforated pipe detail will no longer be used. Back to Back width was erroneously called out as 31' in previous manuals. Wood posts break off or get pulled out too easily. Moisture proofing type specified. Chimney seals added to help prevent water infiltration. Wood posts break off or get pulled out too easily. A steel post is detectable. PHakansonaa Anderson Assoc., Inc.
