Gillett Source of Funds: Department: Public Works Account Number: Contingency Fund Report: Resolution: Ordinance: x Amount Budgeted: N/A Exhibits: Ordinance Amount Requested: $33,127.00 Exhibits: Professional SeJ'vices Al!:reement Budgeted Item: NO Exhibits SUMMARY & RECOMMENDATION Harris County is soon to complete the construction of Bay Area Blvd. from Fairmont Parkway to Spencer Highway. As a component of this Project, the City constructed the Bay Area Blvd. Trunk Sewer from Fairmont Parkway, across Spencer Highway to 0 Street, eliminating a Lift Station and diverting flows from the South 16th Street Service Area to the Fairmont Trunk Sewer. The Engineer, Wayne Smith Engineering, also examined the potential to divert flows as far north as possible from the Northwest Service Area, with the idea of eliminating as many lift stations as possible. This study was done to accommodate the future needs of the area when the Sens Road Widening Project would be started, as city utilities will need to be relocated at that time. This Project has not been expected to take place in the near future, so funds have not been programmed into the City's five (5) year CIP. Recently the city has discovered that Harris County is actively designing this Project, using two (2) design firms, and design could be completed within the next year, with possible construction after that time. The City has contacted one of the County's engineers, Van De'vViele Engineering, to provide a proposal to perfoml Preliminary Engineering Services to installation ofa new 12 inch water line and the extension of a gravity sanitary sewer trunk sewer along Sens road from North 0 Street to North P Street. The work will involve examining the feasibility of extending the existing Bay Area Blvd Trunk Sewer as far north as possible, eliminating as many lift stations as possible, which will also serve to relocate existing sewer from the proposed Sens Road Widening. Additionally, the existing 8 inch waterline will be upsized to 12 inch and relocated outside the proposed Sens Road Widening. The Preliminary Engineering Report will summarize the findings, make recommendations and provide a cost estimate for crp programming. The cost for the proposed services is as follows: Preliminary Engineering Report Survey Direct and Misc. Expenses Total $25,360.00 (Lump Sum not to exceed) 6,017.00 1,750.00 $33,127.00 The City did not anticipate this Project for several years, and no funds have been budgeted. Due to the accelerated schedule adopted by the County to move forward with the widening of Sens, it is vital that the City determine location and cost of the relocation of utilities outside the proposed construction area, and to implement the previously planned sewer improvements at the same time. Once costs have been established, the city can plan for the orderly relocation of its utilities in advance of the Sens Road Widening Project. Funds are available in the Utility crr Fund Contingency for this Project. Action Required by Council: Approve an ordinance authorizing the City Manager to execute and agreement with Van De Wiele Engineering Incorporated to provide professional engineering services for a Preliminary Engineering Report for the relocation of utilities along Sens Road. fB/ob Da r ORDINANCB NO. 2006- ii10 AN ORDINANCB APPROVING AND AUTHORIZING AN AGRBBMBNT BBTWBBN THB CITY OF LA PORTB AND VAN DeWIBLB BNGINEBRING INCORPORATBD TO PROVIDB A PRBLIMINARY BNGINBBRING RBPORT FOR THB RBLOCATION OF UTILITIBS ALONG SBNS ROAD, APPROPRIATING THB SUM NOT TO BXCBBD $ 3 3, 127 .00, TO FUND SAID CONTRACT, MAKING VARIOUS FINDINGS AND PROVISIONS RBLATING TO THB SUBJBCT, FINDING COMPLIANCB WITH THB OPBN MBBTINGS LAW, AND PROVIDING AN BFFBCTIVB DATB HBRBOF.

Street La Porte, Texas 77571 Re: Proposal for Preliminary Phase Engineering Services Water Main & Sanitary Trunk Sewer Improvements. Sens Road and Adjacent Service Areas Dear Mr. Gillette: We are pleased to submit this proposal to provide professional engineering services for the preparation of a Preliminary Engineering Report for the installation ofa new 12-inch diameter water main and the extension of a gravity sanitary trunk sewer along Sens Road from North D Street to North P Street. This proposal addresses your request for proposal made during our August 2, 2005 and January 18, 2006 meetings. This proposal includes the project's background, scope of services, compensation and project schedule. Background The City of La Porte prepared a "Comprehensive Wastewater Collection and Treatment Plan" in May 1984 (Plan) which has generally been followed. Several service area and service line changes have been necessary to facilitate occurring land development. The main gravity trunk sewer along Fairmont Parkway was constructed. In March 2001 a Preliminary Engineering Report (0301 PER) entitled Preliminary EnJ!ineerin[! Report Large Diameter Sanitary Trunk Sewer Bav Area Boulevard from FairmontParkwav to North D Street was prepared by Wayne Smith & Associates, Inc. for the City of La Porte. The report presented a review and analysis of the city's existing wastewater collection system for the service areas north ofFairmont Parkway and east and west of Sens Road. It included surface and subsurface conditions, and rights-of-way and utility pipeline impacts. It evaluated the gravity sanitary trunk sewer capacities for the existing and future development, and described design criteria and factors affecting the routing of a Mr. Steve Gillette January 27,2006 Page 2 of5 new gravity sanitary trunk sewer. It also examined the potential elimination of the lift stations at Sens Road and North D Street, and Sens Road and North L Street. Subsequent to the 0301PER, a 42-inch diameter gravity sanitary trunk sewer was constructed along Bay Area Boulevard from Fairmont Parkway to Spencer Highway, and a 36-inch diameter gravity sanitary trunk sewer was constructed along Sens Road from Spencer Highway to North D Street. The lift station at North D Street was eliminated. The Harris County Public Infrastructure Department's Engineering Division has two engineering design contracts currently underway for the widening of Sens Road. Binkley & Barfield Consulting Engineers, Inc. (BBI) is designing Sens Road from 300-ft. north ofSoencer HiJ!hwav to 300 ft. north of North H Street. and Van De Wiele Engineering, Inc. (VEl) is designing Sens Road from 300 ft. north of North H Street to 300 ft. north of North P Street. The City of La Porte wants to build upon the findings and recommendations of the 0301 PER, and the BBI and VEl designs and investigate both extending the gravity trunk sewer along Sens Road from North D Street to North P Street, and extending gravity sewer mains east and west along the intersecting streets (North D, West Barbour's Cut Boulevard, North H, North L and North P) to the furthest feasible extent. The primary goal of the investigation is to redirect sewage flows which are currently being diverted, and in some cases pumped, through other service areas to other trunk sewers, into the proposed system as was originally intended in the Plan. By so doing, the secondary goal of the investigation will be realized: eliminating a') many of the city's existing wastewater lift stations within these service areas as possible. The City of La Porte wants to construct the Sens Road portion of the proposed gravity sanitary trunk sewer, as well as a new 12-inch diameter water main (and abandon an existing 6-inch line) prior to the construction of the County's roadway projects. Once constructed, the gravity trunk sewer and water main must coexist with the drainage and roadway improvements such that all can be maintained. Scope of Services 1) Obtain available Sens Road topographic survey data from the BBI and VEl projects. 2) Supplement the topographic survey data in Item 1 with additional, limited topographic survey data (using GPS methods on the same datum) along the intersecting streets and within the service areas. The data shall include but is not limited to: ~nDe~ele Engineering Incorporated VanDe~ele Engineering Incorporated Mr. Steve Gillette January 27,2006 Page 3 of5 a. Cross sections of the intersecting streets at approximately 500- feet on center for various distances; b. Manhole rim elevations, pipe diameters and alignments, and flowline elevations of existing gravity sanitary sewers; c. Pipe diameters and invert elevations of existing lift stations' influent sewers; d. Natural gas or other product pipelines that cross either Sens Road or the intersecting streets; and, e. Above ground utility company facilities such as telephone company pedestals, gas valves, or fiber optic cable risers. 3) Review the 0301 PER's findings and recommendations including service areas, waste load factors, line capacity, location, and constructability. 4) Review the BBI PER and assess the feasibility and cost to extend the proposed gravity trunk sanitary sewer through their project. Participate in two coordination meetings to accomplish this task. 5) Review the topographic survey data from Items 1 and 2 with respect to existing sanitary sewers and lift stations, surface elevations, roadside ditch and cross drainage structure flowline elevations, rights-of-way, easements, and crossing utilities, pipelines and other subsurface conditions. 6) Refer to City of La Porte's current zoning map and develop waste load factors for each service area. Calculate required pipe sizes and slopes based on resulting flow estimates. Include appropriate peaking and infiltration/inflow factors. 7) Determine the extents to which the proposed gravity trunk and main sanitary sewers can be extended throughout the service areas. Provide pipe sizes, slopes and preliminary flowline elevations at key nodes. Identify lift stations that can be removed from service. 8) Participate in three meetings with the Harris County Public Infrastructure Department's Engineering Division project manager. The first two will address impacts, scheduling, feasibility, constructability and coordination with the County and BBI; the third to secure design concurrence. Mr. Steve Gillette January 27,2006 Page 4 of5 9) Prepare an estimate of probable construction cost showing each major portion of the proposed gravity sanitary trunk sewer, and each intersecting street's proposed gravity sanitary main sewer. 10) Present the findings and recommendations of the investigation outlined in Items 1 through 8 in a Preliminary Engineering Report prepared under the direct supervision of, and sealed by a licensed Professional Engineer in the State of Texas. Include photographs, exhibits, tables and cost estimates. 11) Furnish up six copies of the Preliminary Engineering Report to the City of La Porte for their review and approval. 12) VEl recommends postponing any geotechnical investigation(s) until the design phase. The final locations and depths of the proposed sanitary sewers will be known at that time. Compensation Compensation for services rendered will be on a lump sum basis at a cost not to exceed $25,360.00 without prior written approval from the City of La Porte. VEl recommends a budget of $6,017.00 (cost plus 10% mark-up) for the services ofa Registered Professional Land Surveyor to perform the limited topographic survey (see enclosed January 26,2006 proposal from Total Surveyors, Inc.). Direct expenses are estimated at $1,750.00 based on reproduction of 6 copies of the Preliminary Engineering Report at $250.00 each and $250.00 in miscellaneous expenses. The calculation of VEl's fee (by task) and the project's overall $33,127.00 budget are presented in Exhibit A. Project Schedule The work will commence upon receipt of the City of La Porte's written authorization. Surveying, field reconnaissance work, records research and agency and utility company coordination can be completed within approximately three weeks of authorization. The service areas can be defined, waste load and In factors applied, base solution determined, costs estimated and a draft Preliminary Engineering Report completed approximately three weeks thereafter. Assuming one week for the city's review, the final Preliminary Engineering Report can be completed two weeks thereafter. VEl therefore recommends a schedule of 60 calendar days to complete the services described herein. ~nDeWiele Engineering Incorporated Mr. Steve Gillette January 27,2006 Page 5 of5 Please indicate your acceptance of this proposal by executing both originals and returning one for our files.
