Home My WebLink About10C - 2011 Water Quality Maintenance and Retrofit Project MEETING DATE: AGENDA #: PREPARED BY: AGENDA ITEM: DISCUSSION: 4646 Dakota Street SE Prior Lake. MN 55372 CITY COUNCIL AGENDA REPORT JUNE 7, 2010 10C ROSS BINTNER, WATER RESOUCES ENGINEER CONSIDER APPROVAL OF TWO RESOLUTIONS: 1) ACCEPTING PROPOSALS AND AUTHORIZING WSB TO PROVIDE SURVEYING AND WETLAND DELINEATION SERVICES; AND, 2) ACCEPTING PROPOSALS AND AUTHORIZING NTS TO PROVIDE TESTING SERVICES FOR THE 2011 WATER QUALITY MAINTENANCE AND RETROFIT PROJECT. Introduction The purpose of this agenda item is to accept the proposals for professional services related to design, construction surveying, wetland delineation and pond sediment testing for the 2011 Water Quality Maintenance and Retrofit Project #11-012. Historv The City of Prior Lake owns the majority of the stormwater conveyance and treatment system (ponds, swales, culverts) that provides flood protection and water quality treatment of rainwater runoff. To keep the system in good working order, and maintain the mandated average designed level of service; periodic maintenance must be undertaken. The city council recently approved such maintenance for 2009 which is presently underway. This agenda item is for work to be undertaken in 2011. The City of Prior Lake inspects its entire stormwater system on a 3-5 year rotating basis. The result of these inspections triggers minor maintenance work that is completed annually by City staff. Inspections also lead to large full pond dredging projects and efficiency and capacity retrofit which occur biennially (currently every odd year). Water quality maintenance and retrofit projects are prioritized and completed based on the following criteria: cost efficiency, current level of service, and rights of access. City staff solicited proposals for surveying and testing services needed to collect information to assist in the process of prioritizing these ponds, and creating maintenance cost estimates and plans. Current Circumstances The 2011 Water Quality Maintenance Project includes five water quality areas. These five areas show signs of underperforming their design level of service and are in need of repair or modification. In order to determine the parameters needed to prepare the plans and specifications for this project the City needs to complete survey/wetland delineation work and testing. The results of the surveying and testing will allow City Staff to produce maintenance plans and cost estimates for full maintenance to be completed from January 1, 2011 through October 31, 2011. R\CounCii201O Agenda Reports\06 07 1CJJOOGCJ7 IGENDA !\ccept Ouotes Survey arid Testing docx Surveying and Wetland Services Staff has requested proposals from the three firms from our consultant pool for surveying services. They include: Bolton and Menk Inc., WSB and Associates, and MFRA. Each of these firms has a positive history of construction staking and wetland delineation services for the City of Prior Lake. The bids received by these firms are tabulated below. Note that MFRA did not respond to the RFP: I Firm Name I MFRA I WSB I BMI , Base Price Nonresponsive $4,980.00 $10,700.00 The proposals received were analyzed and City staff is recommending that WSB perform the surveying and wetland delineation services for this project. WSB has performed the construction staking and wetland delineations for City utilities in the past. The quoted represent a "Base Bid" that was based on assumptions about the amount of ponds to be maintained. Final determination on the amount of survey work required will depend on the final design estimated costs and any contamination detected during testing. These factors will determine whether the City will complete maintenance on less than or more than five areas based on budget constraints. Soil Testing Services Staff has requested proposals from the three qualified testing firms. They include: NTS, Braun Intertec, and Pace Analytical. Each of these firms has the unique ability to provide the State-mandated soil tests: I Firm Name I NTS I Braun Intertec I Pace Analytical . Base Price $4,532.00 $5,225.00 $6,420.50 The proposals received were each analyzed and City staff is recommending NTS to perform the soil testing services for the 2011 Water Quality Maintenance and Retrofit project. NTS performed similar services for the 2009 pond maintenance project and met the timelines and testing requirements. Each firm provided a "Base Bid" based on assumptions of numbers of tests required. The testing protocol requires a varying level of effort based on the sample content and a predefined decision matrix. The actual cost will vary depending on the soil sample content. ISSUES: Surveying, wetland delineation, and soil chemical tests must be done by or under the supervision of a registered land surveyor, or certified testing laboratory and thus qualifies as a professional service. The City of Prior Lake is not equipped or licensed to perform surveying and testing for these projects. FINANCIAL IMPACT: The surveying and testing for this project will be funded through the City Water Quality utility, capital outlay budget item #49420-530.
