City Council approval requires a simple majority vote of the City Council present." BACKGROUND At the May 9, 2011 Council work session, staff discussed the 2012 street reconstruction project with the Council. DISCUSSION The Capital Improvement Program includes the reconstruction of the streets in the Minnewashta Heights neighborhood next year. The streets —E„ 11 3 3 Project Location proposed for reconstruction were chosen using the City's Pavement Management Program and were identified due to utility problems in the area. The streets in Minnewashta Heights are 40 years old and cannot be cost effectively repaired with minor maintenance or even a bituminous overlay. The streets were sealcoated in 1994 and 1999.

Ui UJ 0 � � U — f Ego 1 I a �0 , 1 PCII- 64 Esiirnate} PC ' 48 1 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. The watermain in this area is cast iron pipe and has eight documented breaks. The sanitary sewer will be televised to determine its condition and if there is inflow /infiltration into the system. For the 2006 Surface Water Management plan, this area was modeled and a preliminary drainage analysis was completed. Also, several years ago a consultant 1_ was hired to give recommendations for drainage improvements south of Highway 7 in the Minnewashta Landings development to the west. Staff intends to use this information and gather additional information to complete a storm water design for the area. i The project area is developed and streets have 50' right -of- way; therefore there is minimal space to provide traditional storm water management, namely curb and gutter, storm sewer and treatment ponds. Staff may need to look at alternative storm water management systems for this project. Staff plans to meet with the neighborhood in June to discuss the storm water management options. 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. On April 21, 2011, a Request for Proposals (RFPs) for this project was emailed to Kimley -Horn and Associates, Inc. and WSB & Associates, Inc. Both firms submitted a proposal which is summarized as follows: G:\ENG\PUBLIC \_2012 PROJECTS \12 -01 Minnewashta Hts recon\approve consultant contract 05- 23- 2011.docx 2012 Street Reconstruction Project May 23, 2011 Page 3 Kimley -Horn WSB & and Associates, Associates, Inc. Inc. Submitted prior to the deadline ✓ ✓ Proposal format ✓ ✓ Transmittal letter submitted ✓ ✓ Members of the consultant team identified ✓ ✓ Understanding of project ✓ ✓ Total Fee $217,755 $171,509 Construction observation will be done in- house, therefore the totals for both consultants have been adjusted so that only $20,000 is allocated to coordinate construction observation. The main difference in the proposals was the time allocated for the feasibility report preparation, preliminary and final design services, and meetings. Kimley Horn allocated a total of 1,215 hours for these tasks; WSB allocated 756 hours. The WSB project team worked on the Erie Avenue and Red Cedar Point Street and utility construction projects in 2010. Their work has been satisfactory. It is planned to have City staff complete the inspection of the project and most of the construction administration. SCHEDULE If this project moves forward, staff anticipates the following project schedule: Complete Soil Borings June, 2011 Neighborhood Meeting June, 2011 Complete Consultation Report August, 2011 Neighborhood Open House September, 2011 Accept Feasibility Report October, 2011 Hold Public Hearing November, 2011 Bid Opening March, 2012 Assessment Hearing April, 2012 Start Construction May, 2012 Construction Substantially Complete September, 2012 FUNDING Budgets for the proposed work have been included in the 2011 CIP. Assessments are proposed to 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 6% interest. A consultation report should be drafted to help determine the final assessment amount. One Hundred Percent (100 %) of the utility and stormwater improvements GAENG\PUBLIC \_2012 PROJECTS \12 -01 Minnewashta Hts recon \approve consultant contract 05 -23 -201 Ldocx 2012 Street Reconstruction Project May 23, 2011 Page 4 would be funded out of the respective utility funds. It is proposed 40% of the consultant fee associated with the street improvements will be assessed back to the benefiting property owners. The following is the current project budget and funding sources: Fund Total Revolving Assessment fund $1,700,000 Sanitary Sewer Utility fund $300,000 Watermain Utility fund $700,000 Storm water Utility fund $400,000 $3,100,000 The consultant contract will be a time and materials based work not to exceed amount. As with all engineering contracts, the consultant must submit periodic invoices that staff will review before processing. The consultant will be required to submit time sheets verifying the. hours worked on the project and expense sheets. Staff will review the invoices and expense sheets for accuracy and conformance to the contract.

Current 5 -year plan shows the following neighborhood areas: Residential 2011 - Timberwood Drive neighborhood, Saratoga, Santa Vera, Chippewa, Picha and Kerber (S of W 78th), Target lane and W 78th Street (Powers Blvd to Market Blvd) 2012 - Greenbriar, Fir Tree, Elm Tree, Dogwood, Shore Drive and Maplewood Circle (Reconstruction) 2013 - Greenwood Shores and West 78th Street (Powers to Market) 2014 - Dartmouth Drive and Cypress Drive 2015 - Carver Beach area (south and west of Carver Beach Road) Justification The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. Rehabilitation projects extend the life of the street. In cases with utility or poor sub grade needs to be replaced or where streets have deteriorated to a point where rehabilitation will no longer be practical reconstruction of the street is necessary. A feasibility study is written to consider the merits of the project and scope of work.
