Item 4C MemoCITY OF SOUTHLAKE MEMORANDUM (May 18, 2021) To: Shana Yelverton, City Manager From: Rob Cohen, Director of Public Works Item 4C Subject: Approve an Engineering Services Agreement (ESA) with Dannenbaum Engineering Company, LLC (Dannenbaum) to provide engineering design and construction services for mobility improvements at the intersection of FM 1709 and Pearson Lane in an amount not to exceed $160,000. Action Requested: Approve an Engineering Services Agreement (ESA) with Dannenbaum Engineering Company, LLC (Dannenbaum) to provide engineering design and construction services for mobility improvements at the intersection of FM 1709 and Pearson Lane in an amount not to exceed $160,000. Background Information: Pearson Ln is currently a two-lane undivided arterial north of Southlake Blvd (FM 1709) and a two-lane undivided collector south of Southlake Blvd (FM 1709). In the current configuration, the intersection experiences significant congestion during peak hours. The level of service is anticipated to be reduced with the continued development along FM 1709 and Pearson Lane. The project will consist of adding a left -turn lane for the northbound and southbound approach of Pearson Ln at FM 1709. Improvements will increase mobility, reduce congestion, enhance traffic and pedestrian safety, and improve connectivity. Additional improvements include signal timing changes and pedestrian accommodations such as curb ramps, push buttons, and sidewalks. The improvements at the intersection will be a joint project with the City of Keller. A future Interlocal Agreement (ILA) with the City of Keller will result in Keller funding 25% of the total cost for Improvements. Improvements for the intersection were identified as part of the 2030 Mobility Master Plan and reaffirmed via Intersection Capacity Analysis performed by Kimley Horn, dated November 2017. Page 1 of 2 Item 4C Financial Considerations: Funding for this agreement is budgeted as part of the approved Capital Improvement Program. This agreement is within the project budget. Strategic Link: This item links to the City's Strategy Map strategic focus areas of Safety & Security, Mobility, and Infrastructure. It specifically relates to the City's Corporate Objectives, Cl: Achieve The Highest Standards Of Safety & Security, C2: Provide Travel Convenience Within City & Region, and F2: Invest To Provide & Maintain High Quality Public Assets.

SUBSURFACE UTILITY ENGINEERING The scope of this proposal includes Quality Level "B" SUE. Utilities to be designated include gas, telecommunications, electric, traffic signals, storm, water and sanitary sewer. Designating will be performed within the following limits as indicated in Exhibits "A". Quality Level B (QL"B") - Two-dimensional (x,y) information obtained through the application and interpretation of non-destructive surface geophysical methods. Also known as "designating" this quality level provides the horizontal position of subsurface utilities within approximately one foot. Designating Procedures Prior to beginning field designating activities, TRG's field manager will review the project scope of work and available utility records. Once these initial reviews are complete, the field manager and technicians will begin designating the approximate horizontal position of known subsurface utilities within the specified project limits. A suite of geophysical equipment (electromagnetic induction, magnetic) will be used to designate metallic/conductive utilities ( e.g. steel pipe, electrical cable, telephone cable). TRG will establish routine/ordinary traffic control ( cones and free standing signage, etc.) whenever required as part of standard pricing. If non -routine traffic control measures are required (barricades, flag person, changeable message board, etc.), these services will be considered extra. Accurate collection and recording of designated utilities is a critical component of the SUE process. TRG utilizes a proven method of collecting and recording survey information once the utilities have been designated in the field. TRG's field manager will produce detailed sketches depicting each utility as well as relevant surface features such as roadways, buildings, manholes, fire hydrants, utility pedestals, valves, meters, etc. Each utility will be labeled with a unique ID code. For example, if two different water lines exist on the project, one will be labeled WI and the other W2. Paint and pin flags will be used to designate the utilities in the field. A labeled pin flag or paint mark will be used to mark each location where a survey shot is required. The locations will be numbered sequentially for each individual utility line. For example, if there are 10 shots required on water line WI, the points will be numbered WI -1 through WI -10. Quality Level A (QL"A") Test Holes are included in the scope at the quantity and depth as outlined on the attached Fee Estimate. Actual number and depth may vary and will be billed at contracted rate shown on the Fee estimate (plus subconsultant markup). III.

The Engineer shall prepare the following: a. Prepare drainage area maps. b. Design (if applicable) proposed storm drain system. c. Prepare drainage details for outlet protection, outlet structures and utility accommodation structures. d. Select standard details from County, State or District's list of standards for drainage structures and end treatments, etc. e.

Take into consideration utility impacts. ii. Signing and Pavement Markings: All signing and pavement marking will be shown on plan sheets in accordance with TxMUTCD. Engineer shall detail all non-standard signs or marking details required for the project. City of Southlake and TxDOT standards shall utilize whenever possible. viii. SWPPP: The SWPPP shall be developed on separate sheets from (but in conformance with) the TCP, to minimize potential impact to receiving waterways. The SWPPP shall include text describing the plan, quantities, type, phase and locations of erosion control devices and any required permanent erosion control measures. ix. Design Cross Sections/Cut and Fill Quantities: Engineer shall develop an earthwork analysis to determine cut and fill quantities and provide final design cross sections at 25 foot intervals. Annotation shall include at a minimum existing/proposed right of way, side slopes (front and back). Cross sections shall be developed in OpenRoads. Engineer shall provide all associated electronic files used to generate the design cross sections. x. TxDOT Permit Set: Engineer shall prepare a permit set for TxDOT approval for all work within TxDOT ROW. All construction within TxDOT ROW will be designed in accordance with TxDOT standards. Engineer will coordinate with permit office and TxDOT North Tarrant Area Office to obtain a permit for the project. xi. Provide all standard design sheets applicable to project. In the absence of City of Southlake standards the Engineer shall use TxDOT with approval of the City. xii. Coordinate with franchise utilities on project design. Transmit Plans Adequate for Utility Relocation (PAUR) at 60% level to all franchise utilities. xiii. Provide detailed Engineers opinion of probable cost. xiv. Assemble Project Specification Manual with contract, bid schedule, and specs from City of Southlake as applicable. IV. BID AND CONSTRUCTION PHASE SERVICES a.
