Alyson Fauske, Assistant City Engineer August 24, 2015 6 W10 d p -3 2016 Street Reconstruction Project No. 16 -01: Approve Consultant Contract; Authorize Preparation of Feasibility Study PROPOSED MOTION "The City Council is recommended to approve a consultant contract in the amount of $208,737.00 with WSB & Associates and authorize the preparation of a feasibility study for the 2016 Street Reconstruction Project, No. 16 -01. City Council approval requires a simple majority vote of the City Council present." The Capital Improvement Program has planned for reconstructing the Minnewashta Manor area (north of Lake Minnewashta) next year. The streets in Minnewashta Manor were selected using the City's Pavement Management Program and site investigations. The streets in this project area were constructed in 1971. The streets are in poor condition with pavement condition indices ranging from www.ci.chanhass Webss en.mous 9 to 47, with an average of 31. A PCI of 100 represents a new street. Streets with a PCI below 45 typically indicate distresses that require a full reconstruction, therefore it is no longer cost effective to repair the streets with minor maintenance or perform a bituminous overlay.

The feasibility study will: • Identify and address existing infrastructure and drainage issues • Review existing City and Minnehaha Creek Watershed District (MCWD) hydraulic and hydrologic models for issues • Provide possible solutions to identified issues Address current National Pollutant Discharge Elimination System (NPDES) and MCWD requirements • Identify if project scope exceeds the threshold for each agency and design accordingly • Identify potential areas for water quality treatment • Identify potential areas for abstraction through infiltration, capture and use or other methods • Provide discussion of infeasibility if that is the findings • Identify areas where increases in impervious surface may be minimized • Review City wetland protection plan, MCWD wetland protection plan, National Wetland Inventory (NWI), Public Waters Inventory (PWI) and other available resources for potential wetlands within the project area, delineating wetlands where necessary. There are overhead private utilities within the project area. The private utility companies will be notified of the proposed project and asked to provide an estimate to bury the utility. Should the neighborhood wish to pursue burying the private utilities, 100% of the cost will be assessed to the benefitting property owners. Project Financing Budgets for the proposed work have been included in the 2015 CIP. The budgets will need to be reviewed and updated based upon current construction cost estimates and after the feasibility report is drafted. Assessments will be based off the City's assessment practice of assessing 40% of the street improvements to the benefiting properties on a per lot basis. The assessments would be proposed for 10 years at a preliminary 6% interest rate. A consultation report will be drafted to help determine the final assessment amount. The Engineering Department will host neighborhood meetings to answer resident questions about the proposed improvements and assessments. These meetings also give staff an opportunity to gather additional information about the area to help make the project successful. Engineering Services Consultant engineering services would be needed for the street project. The engineering services would include feasibility report preparation, final design and construction administrative services.

While proper preventative maintenance extends the of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. abilitation projects extend the life of the street. In cases when utilities or poor sub grade needs to be replaced or where streets have :riorated to a point where rehabilitation will no longer be practical, reconstruction of the street is necessary. A feasibility study is written to sider the merits of the project and scope of work. Highway 212 improvement project included a pedestrian trail along the first 2,500 feet of Bluff Creek Drive. The resulting "gap" represents a ;ing link in the City's trail system south to Flying Cloud Drive. Bluff Creek Drive is a difficult stretch of road to negotiate as a pedestrian in 3hsence of a trail. This trail seement is nlanned to be constructed alone with the 2017 MSA street reconstruction.

Project Understanding This project involves the reconstruction of the streets and utilities in the Minnewashta Manor neighborhood. The streets within the project area are as follows: • Minnewashta Woods Drive • North Manor Road • Orchard Lane from North Woods Drive to Minnewashta Woods Drive • Sandpiper Trail • Tanagers Lane • Washta Bay Road The overall project area is very similar to the Minnewashta Heights neighborhood in that streets are rural without the presence of a formalized drainage system. There is a storm sewer in the northwest corner of the site which drains back to the north into the ditch along TH 7 to the pond in the northeast corner of the project area. One of the primary goals for the project is to construct these streets to urban section containing concrete curb and gutter, along with a sand subgrade section with draintile. The challenge the City is faced with in accomplishing this goal is the development of a formalized drainage system and stormwater management plan that will address runoff and treatment concerns prior to discharging into Lake Minnewashta. With this project, the City will be working with its selected consultant to identify and evaluate potential options for stormwater management that will be incorporated into the final plans for the reconstruction project. Access will be a primary concern during construction. There are two primary access points to TH 7 from the project area, and one will need to be maintained at all times. The design development will need to address traffic control and access with MnDOT to allow for continued traffic while staging the street and utility construction within the neighborhood. The watermain in the area consists of old cast iron pipe with a substantial history of breaks. WSB will coordinate the geotechnical exploration for the area to determine if soils are aggressive and Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 7 what necessary construction techniques and materials may be required to extend the longevity of the pipe. Based on the physical constraints on the site, trenchless processes for replacement of the watermain, including pipe bursting and directional drilling, will be evaluated and included as alternate bids for the watermain installation. The City will be completing the televising of the gravity portion of the sanitary sewer system in the project area. The selected consultant will be responsible for reviewing the televising logs and reports and recommending system improvements, potentially including point repairs, chemical and grout sealing of joints and manholes, and replacement of sections of the pipe that are sagging and holding water. Final improvements to the system will be selected by the City based on the consultant's recommendations. Similar to the 2012 Street Improvement project, this project is also on Lake Minnewashta and has the same permitting requirements. We anticipate that public involvement will be critical to ensure that resident and council concerns are addressed to the maximum extent possible. The project is proposed to be partially funded with levied assessments. This will require the project improvement process to be completed in accordance with Minnesota State Statutes Chapter 429. Work Plan /Approach Based on our understanding of the project, WSB proposes the following scope of services. A proposed schedule can be found on page 13. This schedule presumes award of the consultant contract in mid - September and estimates substantial completion in 2016, with final completion of the project byJune 2017. TASK 1 - Design and Bidding Services 1.1- Project Management Project management is an essential task that WSB includes in each project to maintain an open line of communication between the City of Chanhassen and the WSB team. Proper execution of this task allows us to monitor project progress in relationship to project budget in order to minimize schedule slipping and scope deviations. This task also involves quality assurance and control reviews of documents and processes to maximize efficiency in the project development process. 1.2 - Surveying for Design Services /Data Collection Initial underground data to be collected will be primarily based on a Gopher State One Call design locate. Following the locate call, WSB will contact each private utility company to inform them of the Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 8 project and to gather mapping of individual private facilities within the project site. Other work performed and information to be collected will include: • Topographic survey- WSB will perform the design survey at this stage to create accurate base mapping and provide for accuracy as part of the feasibility study. The preliminary design survey will be completed using conventional survey methods with invert verification of sanitary and storm sewer structures. • Base mapping - Base mapping will be created from the survey data collected. Information on private and public utilities will also be incorporated into the base map in order to identify potential conflicts at the feasibility level. As an added benefit, base mapping and design will be created utilizing 3 -D Civil Design in AutoCAD. WSB has developed design templates specifically for use in drafting and designing with the 3 -13 program. Those templates will be provided to the City, along with all base files for the project at no additional cost to the City. The time and associated fees for data collection have been listed in the task hour charts according to each respective project area. 1.3 - Environmental /Natural Resources Review WSB will prepare a technical report identifying boundaries and mitigation requirements necessary based on potential impacts from the proposed project. This task will be comprised of the following • Wet /and delineation- WSB will perform an on -site wetland delineation of the defined project area, in accordance with the US Army Corps of Engineers Wetlands Delineation Manual and applicable Regional Supplement (Midwest Supplement). The US Fish and Wildlife Service National Wetlands Inventory Map indicates that wetlands exist near the project area. These mapped wetlands are associated with a shallow marsh wetland, located northeast of N Manor Ave, as well as Lake Minnewashta, located to the southwest. The US Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) Web Soil Survey for Carver County indicates hydric soil types are mapped at these locations. • MN Department of Natural Resources IDNR)Pubiic Waters - If the project involves work below the ordinary high water (OHW) level of a Lake Minnewashta (or any other DNR public water), then survey or determination of the OHW will be required, and permits will be coordinated through the DNR MPARS online permitting system. The project is located within the Shoreland Overlay District, associated with Lake Minnewashta. 1.4 - Stormwater Management Planning Stormwater management -WSB will perform a hydrologic analysis of the project area to comply with City and watershed requirements. BMPs will be identified for strategic locations to provide the most effective level of treatment, rate, and volume control for the money. Topography, soil conditions and Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 9 other site constraints will be reviewed to determine the best methods and combinations of proposed improvement features. The proposed facilities will be reviewed for ponding and storage, as well as for phosphorus and solids removal rates. We will meet with MCWD to review the options, as permits will be required for this project. 1.5 - Preliminary Design WSB will complete a preliminary design for all components within the project, which will serve as the basis for the feasibility study. The preliminary design will address the following features: • Street center line profile- We anticipate that existing grades in the project area will closely match existing centerline profiles. The topographic survey for the project area will be closely analyzed to identify drainage problems. It is the intent to add curb and gutter and the feasibility will need to be addressed with the stormwater management component of the project. This area is restricted with limited right of way. The profile will need to be set to minimize elevation impacts and disturbance to private property and make certain that safe and reasonable access is provided to the residents. The centerline grades will also need to be set to allow for the accomplishment of the drainage and stormwater management set with the City's study of this area. • Watermain replacement - Street and right of way widths in the project area are limited. However, there is a substantial number of physical barriers immediately adjacent to the right of way lines and the site which could be impacted with traditional open trench replacement for the watermain system. As part of this task, we will evaluate trenchless replacement options including directional drilling and pipe bursting. The preliminary design for this area will develop requirements for a temporary water supply system and the overall plan for the replacement system. • Sewer televising review -The City will be televising the gravity sanitary sewer system within the area as part of the feasibility study. WSB will review the sanitary sewer televising reports and records collected by the City and generate a list of recommended improvements for the City to determine the final improvements to be incorporated into the final design of the project. • Stormwatercollection system -WSB will perform a hydrologic analysis of the project area utilizing any information provided by the City, as- builts, and available topographical maps. We will design a stormwater conveyance system to City standards to fit with the proposed project. Curb line installation and design will match the proposed drainage and collection improvements. • Stormwater management - WSB will perform a hydrologic analysis of the project area to comply with City and watershed requirements. BMPs will be identified for strategic locations to provide the most effective level of treatment, rate, and volume control for the money. Topography, soil conditions and other site constraints will be reviewed to determine the best methods and combinations of proposed improvement features. The proposed facilities will be reviewed for ponding and storage, as well as for phosphorus and Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 10 solids removal rates. We will meet with MCWD to review the options, as permits will be required for this project. • Right of way /easement acquisitionidentif %cation - Once the preliminary design is completed for both project areas, WSB will prepare an overall map identifying the location of additional right of way and easements needed for construction. The extent of right of way and easement acquisition is unknown at this time. As a result, the scope of services proposed herein does not include the preparation of legal descriptions, exhibits, or easement negotiation services. These services may be negotiated following the completion of the preliminary design phase of the project. • Private utiiitycoordination- WSB will coordinate with Xcel Energy to determine the costs and design of burying the overhead power lines in the areas. This information will be gathered early on in the process so it may be presented to residents at the initial neighborhood meeting, as this is usually an additional cost to residents above and beyond the street improvement assessment. 1.6 - Coordinate and Obtain Geotechnical Engineering Services The request for proposals provides an allotment for geotechnical engineering services for each of the project areas. WSB will contract and coordinate these services for design and construction materials testing. A soils report and documentation of materials testing during construction will be provided to the City. 1.7 - Pavement Design Report WSB will review existing pavement distresses in conjunction with soils recommendations from the geotechnical exploration conducted with this scope of services. This will allow the development of a pavement section for both project areas that will address anticipated traffic loading and subgrade soil conditions, as well as document the design and justification for the new pavement section to be constructed with the project. This will be a technical report submitted independently of the feasibility report and project plans and specifications. 1.8 - Feasibility Report Based on the approval of the preliminary design by City staff, WSB will prepare the feasibility report which will include: • Report text • Graphics depicting proposed improvements • Engineer's opinion of probable cost • Preliminary assessment roll Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 11 As part of the feasibility report, WSB will prepare a presentation and handout materials for the public hearing, as well as attend and facilitate the public hearing as needed. 1.9 - Final Design /Plan Preparation Input from residents at neighborhood meetings and the public hearing will provide the basis for the final design and plan preparation. Once the City Council has ordered the public hearing, WSB will complete the final design for the following elements: • Roadway geometrics, including typical sections and pavement design • Profile grades, evaluated and set relative to driveway grades and touchdown points • Stormwater collection system • Stormwater management facilities • Temporary water supply system requirements • Watermain • Sanitary sewer repairs as needed All elements of the final design will be documented in the construction plans prepared for the project. The construction plans will also detail miscellaneous items necessary for the construction. The final plan set may consist of the following plan sheets as well as others necessary for bidding the project: • Title sheet • General construction details • Storm water management facilities details • Removal sheets • Street and storm sewer plan and profile sheets • Watermain and sanitary sewer plan and profile sheets • Surface water pollution prevention plan (SWPPP) • Restoration and turf establishment plans • Cross - sections Quantities will be calculated and tabulated on a bid proposal form that will be distributed with the plans and specifications for potential bidders to submit their individual bids. 1.10 - Project Manual The project manual will be prepared based on the City of Chanhassen's standard specifications for construction and will contain all contract documents relating to the project. Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 12 1.11 - Permits Based on the nature of the construction and overall size of the project, the following permits will be prepared and submitted on behalf of the City: • Minnesota Pollution Contra /Agency- NPDES Construction Activity Permit • Minnehaha Creek Watershed District - Stormwater Management Rule • Minnehaha Creek Watershed District - Wetland Conservation Act • Minnesota Department of Natural Resources - Public Waters Works Permit (if necessary to tie in outfalls at the lake) • USArmyCorps of Engineers- Section 404 Federal Clean Water Act (if wetlands are deemed jurisdictional) • Minnesota Pollution Control Agency- Section 401 Water Quality Certification • Minnesota Department of Health - Watermain Plan Review 1 .12 - Bidding Services Upon authorization from the City Council to bid the project, WSB will provide bidding support services including plan and specification reproduction and distribution, fielding questions from potential bidders and providing a final engineer's opinion of probable cost. WSB will also attend the bid opening, prepare a tabulation of bids received and letter of recommendation for contract award. 1.13 - Preparation of Assessment Rolls WSB will prepare the preliminary assessment roll at the feasibility stage of the project, based on preliminary costs. The assessment rolls will include all necessary information including parcel identification numbers, property owner name and address, along with the basis of assessment and assessment amount. The preliminary assessment roll will be updated based on the bids received for the project at the time of the assessment hearing, prior to beginning construction. 1.14 - Meetings Work completed under this task will include project meetings listed as follows: • Preparation of meeting materials and attendance at one (1) City Council meeting • Preparation of meeting materials and attendance at three (3) neighborhood informational meetings • Up to 16 hours of progress meetings with City staff and project residents concerning the project Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 13 TASK 2 - Construction Surveying Services Upon award of the construction contract, City staff will take over the project and complete the tasks associated with contract management and administration. In addition, the City will provide the personnel necessary to coordinate construction observation along with coordination of materials testing and construction surveying. WSB will provide a survey crew to complete construction staking of the following items: • Watermain • Storm sewer • Curbline staking • Pond grading stakes as necessary • Blue topping • Subgrade tolerance verification • Miscellaneous staking as needed TASK 3 - Preparation of As -Built Drawings, Including Necessary Surveying Work A draft of the as -built drawings will be completed and delivered to the city for review within one month following the completion of the construction. Final edits will be made to the drawings and delivered in Mylar format within two weeks following the review by City staff. Services necessary for the completion of the as -built drawings will include the following: • Surveying to locate and identify as -built elevations for hydrants, valves, structures, and curb stops • Structure measure -downs • Record drawing preparation • Individual service tie cards based on measurements provided by the City construction observer The scope of services as proposed herein is based on services identified as necessary in the RFP from the City, review of the project site, and discussions with City staff. Consultant Fee Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 14 The proposed scope of services presented herein has been outlined in a task hour chart, which identifies the number of hours associated with each subtask in the overall work program. Individual rates listed in the task hour budget are based on WSB's rates for 2011 (a complete fee schedule is shown on next page). The proposed project schedule will extend from 2015 to 2017 for the final completion date of the construction. Typically, engineering fees increase annually for inflation. However, WSB will honor the prices as proposed in this proposal to aid in maintaining the City's budget, so it does not increase, resulting in higher overall project costs upon completion. The proposed hours listed in the task hour budget for Construction Services includes construction staking and office support during construction from May to September 2016. Based on our understanding of the project, knowledge of the site and discussions with City staff, WSB is proposing to complete the base project as proposed for a not -to- exceed fee of $208,737.00 Exceptions and Deviations Easements and Right Of Way Acquisition The project area currently has limited stormwater collection and management features. Depending on the proposed improvements that develop from the hydrologic study outlined in this proposal, easement acquisition may be necessary. However, the extent of this work is unknown at this time. Therefore, services for easement acquisition are proposed to be billed on an hourly basis up to a not -to- exceed fee that will be negotiated prior to any work completed on the easement acquisition process. Services relating to this work would include the following: • Prepare legal descriptions and exhibits -This work would include the writing of legal descriptions for the areas of right of way and drainage and utility easements identified as necessary for the construction of the project. • Notification, field title investigation, and report -This task includes one on -site visit with each parcel, documented notification, field title report, parcel review, and initialization. This task also includes coordination with surveys, the appraiser, and the review appraiser. • Offer to purchase -This task includes one meeting with the City, one on -site meeting with each parcel, and the formal offer package. This task also includes coordination with the City Attorney. • Appraisal and appraisal reviews -WSB is also able to engage a qualified appraiser and review appraiser for the required appraisals. It is estimated that the one appraisal and appraisal review could be obtained for approximately $4,000. A firm price estimate can be obtained once we have provided the parcel information and specific acquisition area to the appraiser. At that time, they would be able to determine the type of appraisal required and then we would enter into an agreement with an agreed cost for the appraisal and review. Mr. Paul Oehme, PE 2016 Street Improvement Project City Project No. 16 -07 August 20, 2015 Page 15 • Negotiation and settlement -This task includes one meeting with the City, one on -site meeting with each parcel, and three hours of negotiation, document revisions, and settlement writing, if needed. This task also includes coordination with the City Attorney, recordkeeping, and finalized parcel files. Construction Schedule The proposed construction schedule stated in the RFP lists a June 2016 to August 2016 timeframe for the selected contractor to reach substantial completion for the construction. Based on our experience regarding these types of projects, we feel the duration of the contract may be longer than expected (i.e. May 2016 to September 2016). This may need to be addressed during the final design of the project to make certain the contractor has adequate time to complete the project and allow the City to acquire acceptable pricing for the work.
