Scope of Improvements In preparing the feasibility report the consultant relied on soil tests and core sampling to augment the City's pavement management analysis. A pavement evaluation report based on the additional soil tests helped in determining the following recommendation: 8th Ave. (1st S1. N. to Excelsior Blvd.) Mill and overlay 11 th Ave. (Smetana to South Landmark Trail) Reconstruct 14th Ave. (4th St. N. to S. Service Drive) Reconstruct 16th Ave. (1S\ S1. N. to 2nd St. N.) Reconstruct Water main upgrades include gate valve replacement, hydrant upgrades and relocation, replace service lines where necessary. Sanitary sewer improvements include manhole and main replacement where necessary. Storm sewer upgrades include an additional pipe system in 11 th Ave. South to benefit the Westbrooke Patio Homes site and in 16th Ave. North. Amenities recommended are reconstruction of the trail system along the east side of 11th Ave. South. . Public input Two public information meetings were conducted and a questionnaire sent in the mail. .. Costs and assessments The total estimated project cost is $1,076,043.00. This includes a 10% contingency and engineering / admin. costs at 25%. Of this amount, $986,453 is subject to the special assessment process. A detail of costs is found on page 14 of the feasibility report. The City's assessment policy provides for abutting property owners to be assessed 70% of actual street reconstruction costs. There is a wide range in preliminary assessment rates and the recommendation is to consult the matrix on page 15 of the feasibility report. .

PRELIMINARY ENGINEERING REPORT 2001 STREET AND UTILITY IMPROVEMENTS CITY PROJECT NO. 00-10 SAP 132~346-16 (11 th Avenue South) SAP 132-353-05 (8th Avenue) HOPKINS, MINNESOTA 1. INTRODUCTION This report examines the proposed street and utility improvements including sanitary sewer, watermain, storm sewer, street reconstruction, and the associated turfrestoration along the following streets: . 8th A venue from First Street North to County Road 3; . II tl1 A venue South from Smetana Road to South Landmark Trail; . 14th Avenue North from Fourth StreetN011h to South Service Drive; and . 16th A venue North from first Street North to Second Street N011h. Specifically the project involves: 1. Replacement of sanitary sewer pipe and point repair of sections of sanitary pipe; 2. Installation of watermain valves and replacement of existing hydrants; . 3. Replacement and improvement of storm sewer pipe and inlets and additions of new inlets and structures; 4. Bituminous street removal and reconstruction; and concrete curh and gutter replacement; 5. Bituminous street milling and overlay; 6. Bike trail construction; 7. Wiring upgrades to street lighting; 8. Sidewalk construction and repair; and 9. Turf restoration in all areas of construction. 2, BACKGROUND This report was ordered by the City Council on September 19.2000. Council Resolution No. 2000-69 was passed requesting that a study be made for the improvement of the streets noted above. The improvements being considered are reconstruction ofthe bitumi nous street and concrete curb, improved . drainage through storm sewer system upgrades, and rcpair to the watermain and sanitary sewer utilities. 2001 Street and Utility Improvements, City of Hopkins BM! Project No. Tll.:20354 Page! - -------- . As a part of this study, underground sanitary sewer and watermain utilities were checked for adequacy ami structural integrity. The project location is shown on Figure 1. Neighborhood meetings were held for the purposes of informing the affected property owners about the improvements being considered and receiving their comments about problems and concerns to be addressed. Also, a questionnaire was distributed to give the adjacent property owners the oppOliunity to provide their input on various project related concerns including sewer services and drainage. A copy of the questiollilaire and meeting minutes are included in the Appendix. 3. EXISTING CONDITIONS The project areas include single family, multi-family, and commercial properties. The neighborhoods are fully developed and well established with mature trees along many urthe boulevards. There are existing sidewalks or paths along all of the streets. 3.1 Streets The existing street widths are summarized in Table I. The variable width along 8th A venue is due to tapers and expansions along the eurb lines. The streets within the project area are aged and exhibit wear and distress due to trafflc loadings. This is evident on the surface by transverse ancllongitudinal cracking, alligator . cracking, the exposure 0 r pavement aggregates, pot holes and minor rutting. Subgrade soil strength testing and core sampling \vas completed by GME Consultants in November 1999 and October 2000 on all the project ~llTa streets. A summary of the existing pavement conditions are listed in Table 1. ^ copy of the pavement evaluation report is included in the Appendix. Hopkins' pavement management system utilizes a pavement condition index (PCI) rating of o to 100. This rating is based on surficial pavement observations. Generally, the indices correspond to a level of most cost effective improvement as follows: 0-30 = pavement reconstruction; 30-60 - asphalt overlay~ and 50-90 = sealcoat and/or crack sealing. This rating system assists in prioritizing ro;ldway improvements and projecting costs for use in the City's pavement management and capital improvements plan. Actual levels of improvements are determined by completing a comprehensive geotechnical evaluation (included in this report) and preliminary engineering repmi. Table 1 also itemizes Califomia Bearing Ratios (e'BR values). Those street sections exhibiting inplace CUR below 20 are considered poor structurally. Strengthening of base materials and/or a thicker hituminous SurL1CC is recommended. . 200 I Street and Utility Improvements, City of Hopkins BMI Project No. Tl 1.20354 Page 2 . 8th Avenue (First Street North to ('ount)' Road 3) 8th A venue is presently classified as a collector street within the project area. The street is flat to minor rolling in nature wi th bituminous surfacing and is delineated with concrete curb and gutter. The pavement has a moderate amount of cracks and shows evidence of previous maintenance including patching and seal coating. The pavement exhibits no obvious signs of extreme deterioration or subgrade failure. There is concrete sidewalk on both sldes of the street. Parking is allowed on both sides of the street from First Street North to just south of Mainstreet. From this pOlnt to Excelsior Boulevard, parking is allowed on the east side only. The existing street layout is shown in Figures 6-8. The south corridor ofthe Hennepin County Parks Southwest Regional Trail exists on the south side of County Road 3 (Excelsior Boulevard). The southwest corner of the intersection of County Road 3 and 8th Avenue has been constructed to accommodate a tllture bike trail along 8th A venue extending north to the north corridor orthe Hennepin County Parks Southwest Regional Trail. The north corridor is located along the old railroad bed between Main Street and First A venue North. Currently no delineated cOlmection exists between the north and south corridors. 11 th Avenue South (South Landmark Trail to Smetana Road) 11 tl1 Avenue South is presently classified as a collector street within the project area. The street is flat to minor rolling in nature with bituminous surfacing and is delineated wlth concrete curb and gutter, concrete curb and bituminous curb. The pavement has a significant amount of cracking including some indicative of subgrade failure. There is evidence of . previous maintenance including seal coati ng and a number of patches and pothole repairs. POliiollS of the curb along this segment of 111h A venue South arc sunken. Parking is allowed on both sides of the street. An 8'wide bituminous path is located on the east side of 11 th Avenue along the entire Icngth ofthe project and meanders in and out of the City's right of way. The bituminous path is aged and is exhibiting wear and distress. There is evidence that patchwork has been done on the path, and there are sections of the path with moderate to severe alligator cracking. The existing street layout is shown in Figures 9-11. I-Ith Avenue North (Fourth Sfreet North to South Service Drive) 14th A venue North is classitied as a local residential street within the proj ect area. The street has minimal grade with bituminous surfacing and is delineated with concrete vertical curb and no concrete gutter. The pavement shows significant distress including severe alligator cracking, surface scaling, and minor rutting. Much of this distress appears to be the result of poor drainage along the road edges, a problem typical of flatter streets such as this with no concrete gutter. There is evidence of previous maintenance including seal coating and patching. Much of the vertical curb has sllnk:en. There is an existing cOllerete sidewalk on the west side ofthe street. Sections orthe existing sidewalk show signs of aging, cracking and heaving. The existing street layout is shown on Figure 12. 16th Avenue North (First Streff North to i)'ecoJ1d .')'trcct North) 16th A venue North is classified LlS a local residenti a] street within the proj eet area. The street has minimal grade with bituminous surfacing and is delineated with concrete vertical curb. . 200 I Street and Utility Improvements.

Much of this distress appears to be the result of poor drainage along the road edges, a pro b1cm typical of flatter streets such as this with no concrete gutter. There is evidence of previous maintenance including sea] coating and patching. Much ofthe vertical curb has sunken. There is a concrete sidewalk on both sides of the street for the entire length of the proj ect, most of which is in good condition. The existing street layout is shown on Figure 13.

Service lines within these areas may range from 3/4" to 2" for residential lots or 2" to 6" for some commercial lots. Based on nearby findings, their materials may be copper, iron, steel, or lead. Overall. each service line exposed as a part of any watermain improvement project should be considered for replacement based on its material type, agc. and condition, The existing watcrmain systems are illustrated in Figures 6-13. . 2001 Street and Utility Improvements, City of Hopkins BMI Project No. T 11.203 54 Page 4 . 8th Avenue (First Street North to Counf)' Road 3) The watermain presently serving this segment of8tl1 A venue is a 6" cast iron pipe. There are four (4) hydrants extending from the main and most of the lots fronting 81h A venue are expected to be served off of this line. The water/sewer service department staff noted that the gate valve just north of the intersection of 8th A venue and Mainstreet is leaking. Figures 6-8 illustrate the existing watermain. 11 th Avenue South (South Landmark Trail to Smetana Road) The watermain presently serving this segment of 11 th A venue South is an 8" ductile iron pipe. Within the project limits, watermain pipe is located from Landmark Trail South to Tenth Street South. At the Tenth Street South right-of-way the pipe ties into an east-west 8" ductile iron pipe. No watennain pipe is located on lllh Avenue South between the Tenth Street South right-of-way and Smetana Road. Most of the lots fronting Illh A venue are expected to be served off of this line. Four (4) hydrants are located within the project limits on the east side of 11 th A venue South. The water/sewer service department staff expressed a concern that several of the hydrants are located too close to the curb and should be relocated. Figures 9-] 1 illustrate the existing watermain. . 14th Avenue North (Fourth Street North /0 South Service Drive) The watcrmain presently serving] 4th Avenue N0l1h is a 6" cast iron pipe. A 4" hydrant is located at each end of the block. There are no recent service calls for this watcrmain along this block. Figure] 2 illustrates the existing watennain. 16th Avenue North (First Streef North to Second Street Nor/h) The watcrmain presently serving 16th A venue North is a 6"cast iron pipe. A 4" hydrant is located at each end of the block. There are no recent service calls for this watermain along this block. Figure 13 illustrates the existing watermain system. 3.3 Sanitary Sewer The existing condition ofthe sanitary sewer system was acquired from field topography, as-built information, sewer video tapes, the City's Sanitary Sewer Utility Master Plan, as well as discussions with staff from the water/sewer department. The existing sanitary sewer systems are illustrated in Figures 6-] 3. 8th Avenue (Firsl :)'freef North fo COlllltv Road 3) The sanitary sewer presently serving 8th A venue consists of an 8" vitrified clay pipe. Sewer video logs indicate that much of the mainline along this street has minor cracking along the . 200 I Street and Utility Improvements. City of Hopkins 8MI Project No. TI 1.20354 Page :; . pipes and at the joints. There is also evidence of minor sags and bends in the line. Discussions with City staff, however, indicate that these cracks and sags have not been problematic. No service calls have been recorded in this area over the last ten years. Figures 6-8 illustrate the existing sanitary sewer system. 11th Avenue South (South Landmark Trail to Smetana Road) The sanitary sewer presently scrving 11 th A venue South consists of 10" vitrified clay and rvc pipes. Televised recordings of the existing 10" sewer line revealed three sags along the southernmost segment of the line between Trailwood South and the Tenth Street South right- of-way. These sags amount to approximately 30 feet of pipe length. Televised recordings ofthe intersecting] 5" concrete line running along the Tenth Street South right-of-way and crossing under 1] lit A venue South revealed bends, leaks and debris in the line. Figures 9-11 illustrate the existing sanitary sewer system. 14th Avenue North (Fourth Street North to South Service Drive) The sanitary sewer presently serving 14th Avenue North consists of an 8" concrete pipe. There is evidence that repairs have been made to the mainline, as several sections consist of Vitrified clay pipe. The sanitary sewer video logs indicate minor cracks, and roots at some joints. No significant problems were observed or reported by City staff A discussion with the homeowner at 405 14th A venue North revealed recutTing flow problems along this service line. The homeowner indicated that there may be a portion of broken pipe along the service . line. Figure 12 illustrates the existing sanitary se\ver system. 16th Avenue North (First S'treet North to Second Street North) The sanitary sewer presently serving 16th Avenue North consists of 8" vitrified clay pipes. The video logs indicate that a portion orthe mainline may be sagging and that a small portion of the pipe is cracked. These pipe segments amount to approximately 20 feet. The logs also show that there are minor roots at most of the joints and some of the services. Figure] 3 illustrates the existing sanitary sewcr system. 3.4 Storm Sewer The existing condition of the storm sewer system was detcrmined from field topography, as-bui It information and discussions with City staff. The assessment ofthe existing storm sewer revealed few problems. However, modifications and extensions of the existing system are recommended. later in this report to complimcnt proposed street improvements. The existing storm sewer systems are illustrated in Figures 6- ] 3. 8th A1'('/7ul:' (First Street North to COllnlV Road 3) Runorr 011 8th A venue North from First Street North to the old railroad line approximately 150 feet soutb or First Street NOlih flows to the north into catch basins at the First Street N ortb intersection. Runoff along 8111 A venue from the north corridor of the I Iennepin County Parks Southwest Regional Trail to County Road 3 (Excelsior Boulevard) flows into eight . 200 I Street and Utility Improvements, City of Hopkins 8MI Proiect No. Tl ] .20354 Page 6 . catch basins located along the west side and four catch basins along the east side of 8th Avenue and at the intersections of first Street South and Mainstreet. These catch basins are served by a main line storm sewer flowing south from Mainstreet to First Street South. This main line then flows west along First Street South. Pipe sizes along this portion ofthe proj eet vary from 12" to 42". and the pipe materials consist ofrcinforced concrete and vitrified clay, with the exception of one private lead at First Street South, which consists of PVC pipe. Figures 6-8 illustrate the existing storm sewer system. 11 th Avenue South (South Landmark Trail to Smetana Road) Runoff into II th A venue South between Landmark Trail South and Smetana Road is collected by two catch basins located on II th A venue South near Trailwood North and two catch basins on 11 th A venue South just south ofTrailwood South. The mainline consists of 24" reinforced concrete pipe flowing south along the east side of 11 th A venue. At the Tenth Street South right -of-way, there is one catch basin located on each side ofthe street, draining into a 30" reinforced concrete pipe. The 24" mainline also drains into the east-west 30" line, which Hows to the cast. Four catch basins and a Stonnceptor system are located along Trailwood South, which collect runoff from the Westbrooke Patio I-Iomes. These structures tie into the catch basin on the west side of the street, just south of Trailwood South. The six catchbasins located along lllh A venue South within the project area show signs of aging including differential block . movement, loss of grout, and eroded inverts. There is an existing 30" stub on thc nOlih side ofWestbrookc Way which \vas constructed to serve the Landmark Trail and \Vagonwheel Road intcrsections in the future. Figures 9-11 illustrate the existing storm sewer system for 11th A venue South. 14th Avenue North (Fourth Street North to South Service Drive) Currently no storm sewer pipe is located on 14th Avenue North within the 11mits of this project. Runoffalong 14th Avenue North between Fourth Street North and the South Service Drive flows south to two catch basins at the Fourth Street North/14th Avenue North intersection. figure 12 illustrates the existing storm sewer system for 14Lh Avenue North. 16th A venue North (First Strcct North to Second Street North) Currently no storm sewer plpe is located along 16th A venue North within the limits of1bis project. Runoff along 16th Avenue North between first Street N011h and Second Street North flows south to two catch basins at the First Street North/16th Avenue North intersection. City staff has noted that the lack of mid-block catch basins rcsults in wide storm water spreads and pOl1l1ing along the curblincs of this block.

PROPOSED IMPROVEMENTS tl Bituminous Streets 8th Avenue from First Street North to County Road 3.11 th Avenue from Landmark Trail South to Smetana Road, 14th A venue North hom F omih Street N 011h to South Service Drive, and 16th A venue North from First Street NOlih to Second Street North arc all scheduled for improvements in accordance with the City of Hopkins proposed Capital Improvement Plan. Table 2 describes the proposed street improvements. Figures 2 through 5 ill ustratc thc proposed street sections and summarize the levels of improvement recommended for each street within the proj ect area. 8th Avenue (First Street North to Countv Road 3) The underlying aggregate base and subgrade layers along 8th A venue are in acceptable condition. However, the overlying bituminous pavement along these segments is in need of reinforcement. Therefore, the l1rst 8 feet adjacent to the concrete gutter of 8th A venue will be milled to a depth of2 inches and the width of the street between the existing curbs will be fortified with a 2 inch bituminous overlay. By preserving the existing curb lines within these segments, the new vertical alignment will approximate the inplace aligml1cnt. City staff has also expresscd the desire to connect the north corridor of the Hennepin County Parks Southwcst Regional Trail system north of Mainstreet to the south corridor along Excelsior Boulevard. V mious options for this connection are currently under consideration but outside . the scope of this rcpOl1. 11 th Avenue S'outh (South Landmurk Trail to Smetanu Ruad) The results of soils and pavement testing indicate that the existing street sections along 11 th A venue South between Landmark Trail South and Smetana Road arc underlain with various types of sandy soils. The condition ofthe roadway has reached a point where maintenance procedures such as seal coating or milling and overlaying are no longer cost effective. Therefore, the geotechnical engineer, GME Consultants, Inc., has recommended reconstruction of this street. Their recommended pavement section is over four feet thick and includes a three foot sand subgrade, which already exists throughout much afthe project, 12 inches of aggregate base and 7 1/2 inches of asphal t pavement. New concrete curb and gutter will also be constructed. Any local soft, unstable areas in the subgrade will be excavated and replaced with select granular material as they are encountered during the construction. This pavement design is projected to havc a life span of at least 20 years. 11 th Avenue South currently averages 44' wide within the project limits. 'l'he proposed street width is also 44' and its alignment and profile will he similur to existing. Two 12-foot driving lanes and two 1 O-foot parking lanes will be maintained along this segment of 11lh A venue South. . 200] Street and Utility Improvements, City or Hopkins BMI Project No, Tll.20J54 Page 8 . The bituminous path on the east side of the street will also be reconstructed. A section 01'2 inches of asphalt over 6 inches of aggregate base is proposed. The path currently meanders in and out of City right of way onto private property. The 8' wide path will be reconstructed six feet behind the face ofthe curb. As a result, a four-foot permanent trail easement will be required along the east side of the trail. 14th A venue North (Fourth Street North to South Service Drive) The results of the soils amI pavement testing indicate that the street sections along 14th A venue NOIih between Fourth Street NOIth and the South Service Drive are underlain with various types of silty sand and clayey silt. The condition ofthe roadway has reached a point where maintenance procedures SLlch as seal coating or milling and overlaying are not longer cost effective. Furthermore the lack of an adequate curb and gutter system continues to promote drainage problems along this block. Because the level of underlying utility improvements along this block is relatively minor, reclamation of the bituminous pavement section is proposed rather than full reconstruction. During the reclamation process, the existing bituminous surface is crushed and mixed with the underlying base material. This procedure will create a coarse, stronger base material than already exists and is suitable IDr asphalt paving. No subgrade preparation or excavation is utilized except wi thin those areas of utility improvements or extremely 0 bvious soft subgrade areas. This pavement section, as recommended by the geotechnical engineer, includes an 8- . inch depth reclamation graded to allow 4 inches of asphalt pavement. New concrete curb and gutter will also be constructed. 14th Avenue North is currently 36' wide, within the project limits. It is proposed that the street be narrowed to 30', given very low traffic volumes. The road centerline would remain the same and the additional area behind the new curb would be sodded. No significant changes to the road profile arc planned. 16th Avenue North (First Street Nuuh tu Second Street Nurth) The results of the soils and pavement testing indicate that the street sections along 16th A venue North between First Street North and Second Street North are underlain with various types of silty sand and clayey silt. The condition of the roadway has reached a point where maintenance procedures such as seal coating or milling and overlaying arc no longer cost effective. ^ reclaimed pavement design similar to that expl<1ined for 14th A venue North would be an adequate design for this street. However, because there are more extensive utility improvements induding storm sc\vcr and sanitary sewer, reclamation becomes a less viable option due to the level of disturbance by the utility trenches. Therefore, the geotechnical engineer, GME Consultants, Ine.. has recommended reconstruction ofthis street. Their recommended pavement section is 18 inches thick and includes an 8" granular sub-base. ()" aggregate base, and 4" asphalt pavement. The geotechnical engineer is conGdent that given the existing traffic and underlying soil conditions, . 200] Street and Utility Improvements, City of Hopkins 8M! Project No. TI ] .20354 Page 9 -.---.--- . the life span ofthis pavement section will be at least 20 years. City staff and Bolton & Menk, Inc. agree with this but fcel a less substantial, less cxpensive pavement section, properly maintained during its life, will also have a high probability of lasting at least 20 years. Therefore, we are proposing a section consisting of a 4" asphalt pavement, 6" aggregate base, and a geotextilc fabric to separate the base course from the compacted underlying soils. Local soft, unstable areas will be excavated and replaced with select granular material as they are encountered during the construction. This proposed pavement sections is typical for streets within the City with similar subgrade soils and traffic loadings. New concrete curb and gutter will also be constructed. It should be noted that the assessments for this road improvement will be based on the less expensive, and otherwise viable, reclamation pavement design. The additional costs offull reconstruction due to the associated utility improvements will be assessed to the respective utility funds. 16th A venue North is currently 3D' wide within the project limits. Thc proposed street is also 30' and its alignment will match the existing conditions. No significant changes to the road profile are planned. A summary of the proposed pavement sections and street widths are described in Table 2 below. Figures 2 through 5 in the Appendix illustrate the typical cross-sections. .

However, there are some fire hydrants that require size upgrades. These recommendations are detailed below. Due to the relative age of the existing water service lines, it is recommended that any service lines exposed as a part ofthcse street and utility improvements be individually evaluated and considered for replacement. Any exposed lead service pipes would be required to be replaced by the Department of Health. Repairs or replacements of existing water service lines would be I 00% assessable to the corresponding property owners. Proposed watcrmain improvements are illustrated in Figures 14-21. 8th Avenue (First 5-,'treet North to COlin/v Road 3) The leaking existing gatevalvc along 8th A venue north of Mainstreet, is proposed to be replaced. 11 th Avenue South (South Landmark Trail to Smetana Road) The hydrants located on thc west side of 11 th A venue South at the northeast corner of 'A!estbrooke Way and 11th Avenue South, between Trai1wood North and Trailwood South and at Tenth Street South are located too close to the curb and should be relocated. These three hydrants will be relocated 2 feet behind the curb line. . l-/th Avenue North (Fourth Street North to Soulh Service Drive) The existing fire hydrants located at the northern and southern intersections of 14th A venue are 4" fixtures. It is recommended tlwt these hydrants be upgraded to 6" fixtures to ensure that the minimum fire fighting 110\\ls are available. The proposed hydrants will he located a minimum of2 feet behind the curb line. It is also recommended that an additional gate valve be installed along thl: 6" watcrmain line south of the hydrant at Fourth Street North for maintenance purposes. 16th Avenu1:' North (First Street North to Second Street Nurth) The existing fire hydrants located at the l1ot1hern and southern intersections of 16th Avenue are 4" fixtures. It is recommended that these hydrants be upgraded to 6" fixtures to ensure that the minimum fire fighting flows are available. The proposed hydrants will be located a minimum 01'2 feet behind the curb line. It is also recommended that an additional gate valve be installed along the 6" watennain line south of the hydrant at First Street N011h for maintenance purposes. . 200 I Street and Utility Improvements, City of Hopk ins BM! Project No. Tl1.20354 Page II . 4.3 Sanitary Sewer The information used to evaluate the sanitary sewer's existing conditions included televised recordings of the sewers, as built information. manhole reports, and discussions with the City staiT. Cracked joints are not uncommon in vitrified clay pipe, nor are they necessarily candidates for repair or replacement. Those cracks which are wider than hair-line or are plagued with roots or mineral deposits, however, have a higher potential for infiltration and should be repaired. Sags and flow obstructions such as roots will decrease the capacity of a sewer pipe and may result in backup problems. Due to the relative age of the existing service lines, it is recommended that any service lincs exposed as a part of these street and utility improvements be individually evaluated and considered for replacement. Any repair or replacement of existing sanitary service lines would be 100% assessable to the corresponding property owner. Some ofthe existing sanitary sewer manhole castings may have a smaller diameter. If any ofthese are encountered during construction they will be replaced with larger castings to improve safety and accessibility for maintenance workers when entering the structures. . The proposed sanitary sewer improvements are illustrated in Figures 14-2l. 8th Avenue (First Street North to COUl/'V Road 3) Televised recordings ofthe existing sewer line revealed minor problems throughout the line including minor cracks and sags. Discussions with City staff indicated that therc have not been any service complaints or necessary repairs made to this line for several years. Based on this information, it is not recommended that this sewer line be excavated and repaired in lieu of the mill and overlay improvement proposed for the overlying street. It is anticipated that any required maintenance or repair of this line needed in the near future could be completed using trench less or "no-dig" technologies. 11th Avenue South (S01lth Landmark Trail 10 Smetana Road) Proposed improvements to sanitary sewer along 11th Avenue South include spot repairs along the mainline between Trailwood North and the Tenth Street South right-of-way, using rve pipe for these repairs. It is also recommended that the segments of the 15" concrek sewer crossing I ] tl1 A venue at the Tenth Street South right-of-way be replaced within the 11th A venue right-of-way to prevent future premature failure of these pipe segments under the new roadway. . 2001 Street and Utility Improvements, City of Hopkins 8MI Project No. 1'11.20354 Page 12 . ! 4th Avenue North (Fourth .','Ircef Norlh 10 Soulh Service Drive) No improvements to the sanitary se\\ier along 14th Avenue arc being proposed at this time based on the good service record ofthe line and the lack of significant problems found in the video logs. Based on the service problems described earlier in this report, it is recommended that the homeowner at 405 14th Avenue South at least replace their service line from the main to the right-of-way line. This would eliminate any future need for the homeowner to work within City right-of-way to repair an obviously failing service line. Alternatively, the homeowner may elect to replace the service line in its entirety. Any costs for improving this service line would be 100% assessable to the property owner. ! 6th A venue North (First Street North to Second Street North) Proposed improvements to the sanitary sewer along 16th A venue North include spot repairs of the sags and cracks along the 8" mainline. PVC pipe will be used for the repairs. 4.4 Storm Sewer 8th Avenue (First Street North to COUI1fV Road 3) No storm sewer improvements are being recommended for 8th Avenue. . j j th Avenue Soulh (South Lundmark Trail In Snlctana Road) Recommended storm sewer improvements include the construction of the Stormceptor system on private property at Wagonwheel Road. Four catch basins will also be constructed at Wagonwheel Road, as well as Landmark Trail South. The catch basins will drain into the Stormcert01', improving the watcr quality of the 13-acre runoff area within the Westbrooke Patio Homes. The Stormceptor will remove approximately 68% ofthe total suspended solids in the runoff. Flow from the Stormceptor \vill then be routed to the existing 30" storm sewer stub at Westbrooke Way_ Costs for the construction of this storm sewer system will be 100% assessable to the Wcstbrooke Patio Homes. The six catchbasins located along 111h A venuc South within the project area. which show signs of deterioration as explained earlier in this report, are also proposed to be removed and replaced. 14th Avenue North (Fourth Street North to South Service Drive) The existing catch basin at the 4th Street intersection will be removed and replaced to match the narrower street width. 16th Avenue North (First Strccf North to ,,,'ccond Street North) To improve the drainage along 16th A \'enue North. it is recommended that two catch basins be installed midblock. These catch basins \vi] I drain into the existing catch basin located at the First Street North intersection via a 12" HDPE pipe. The storm sewer pipe connecting the two new catch basins and crossing the street will be 12" Rep. . 2001 Street and Utility Improvements, City of 1 !opkins 8M! Project No. T11.203S4 Page 1 3 . 4.5 Sidewalks The bituminous trail along 11 th A venue South will be improved as described in Section 4.1 of this report. Individual concrete sidewalk panels along 14th and 16th Avenue South that are severely cracked, heaving, or otherwise pose a danger to pedestrians. will be replaced. Private sidewalks leading from individual homes to the street will be removed and replaced as necessary 10 facilitate the street improvements. Sidewalk improvements along gth A venue are under consideration as a part of a separate trail connection plan and are outside the scope of this report. 4.6 Driveway Aprons Any existing driveway aprons along 11 th A venue South, 14th A venue North, and 16111 A venue N0l1h will be replaced with new concrde aprons to match the existing driveways to the new street grades. 4.7 Lawn Sprinkler Systems There may be existing lawn sprinkler systems along the roadways scheduled for reconstruction. The adjacent property owners will need to assist in locating and identifying the types of sprinkler system that arc in place. The contractor will be required to make every effort to preserve the inplace systems during construction. However, for those areas where the street grades require modification, the existing sprinkler systems will he replaced. . According to City policy, the City of! lopkins pays for the cost of the parts and the property owner is responsible for the cost of1he labor for replacing thcse systems that are located in City right-of-way. 4.8 Street Signing and Striping The existing street signing, including stop signs and street name signs, will be removed and reinstalled by the contractor as necessary. The existing street striping will be restriped by the contractor when the project has he en completed. 4.9 Street Lighting The existing street lighting along 11111 A vcnue South. including the pedestrian signal crossing near Westbrooke Way, are served by a direct-buried wiring system. City statfhas indicated a desire to replace this wiring with new wiring inside of a conduit system as a part of this project. Additionally, the feed point for these lights is proposed to be switched to that which serves the remaining street lights along I11h A venue South to the north. This would allow all of the lights along this corridor to operate simultaneously. Finally, City staffhas indicated the need to replace the concrete foundations of the southern-most light fixture on the cast side of 11 th Avenue South due to a settlement problem. Therefore, the existing foundation \vill be removed and a new concrete [rllllldatioll \vill be constructed in its place. 4.10 Turf Restoration The existing trces will be protected from the construction as much as possible. Tn the event . a tree removal is necessary due to street grade changes or otherwise, they will be replaced. The areas disturbed by the construction will be re-graded to match the new street grades and restored with boulevard type sod. 2001 Street and Utility Improvements, City of Horkins BMI Project No. Tll.20354 Page 14 . 5. ESTIMATED COSTS Estimated construction costs presented below include a 10 percent contingency factor. Overhead costs, estimated at 25 percent include legal, engineering, administrative and fiscal costs. Final costs and assessments will be determined by using actual construction costs of the proposed work. Proposed construction costs for the 2001 Street and Utility Improvements (including bituminous street storm sewer, sanitary sewer, watermain, and turf restoration) arc itemized in the tables located in Appendix A and are summarized below. These cost estimates are based upon public construction cost information. Since the consultant has no control over the cost of labor, materials, competitive bidding process, weather conditions and other factors affecting the cost of construction, all cost estimates are opinions for general information of the client and no walTanty or guarantee as to the accuracy of construction cost estimates is made. It is recommended that costs for project financing should be based upon actual, competitive bid prices with reasonable contingencies.

ASSESSMENT RATES The following table provides the estimated cost per front foot along each of the project's streets. According to the City's Assessment Policy, 70% of the project's street costs are assessed to the benefitting properties. Storm sewer, watermain and sanitary sewer improvements are paid for 100% by their respective utility funds, with the exception of the private storm sewer and sanitary sewer service costs listed above. Because this work would not be associated with any mainline construction, these costs will be 100% borne by the corresponding property owner. Because a full reconstruction pavement design is recommended along 16th A venue North due to the utility improvements, where a less expensive reclamation pavement design would otherwise be feasible, only the cost of the reclamation pavement design is used in determining the assessment rates. The additional costs of full reconstruction will be borne by the associated utility funds.

RIGHT-OF -W A YIEASEMENTS/PERMITS . The proposed improvements will be limited to the existing street rights-of-way along 8th A venue. 14th Avenue North. and 16th Avenue North. The proposed improvements along 11th Avenue South will require the acquisition of a 4 foot permanent trail easement along the cast right-of-way line with the exception of Valley Park Condo # 459, where a 10 foot easement is available for trail use. This would allow the proposed bituminous trail to extend outside of the right -of-way by three feet and would provide an additional one foot beyond the trail's edge for maintenance purposes. Temporary construction casements may be needed for work outside the street right-of-way such as driveway apron replacement and turf restoration. Permits will be required from the Minnesota Pollution Control Agency, the Minnesota Department of Health, and the Nille Mile Creek Watershed District for the sanitary sewer, watennain, and storm sewer work, respectively. . 2001 Street and Utility Improvements, City of Hopkins 8MI Proiect No. T 11.20354 Page 17 .
