Item 4L CITY OF SOUTHLAKE 4L MEMORANDUM (October 17, 2017) To: Shana Yelverton, City Manager From: Rob Cohen, Director of Public Works Subject: Approve Engineering Services Agreement with Kimley-Horn and Associates, Inc. for Various Intersection Analyses Citywide — Phase 3 in an amount not to exceed $130,000. Action Requested: Approve Engineering Services Agreement with Kimley-Horn and Associates, Inc. for Various Intersection Analyses Citywide — Phase 3 in an amount not to exceed $130,000. Background Information: Phase 1 of the Intersection Capacity Analysis included traffic data collection for 17 existing intersections and initial recommendations for improvements. Phase 2 included a similar scope of work but added an additional 12 intersections. From these two Phases, 5 intersections (Continental/Byron Nelson, Conti nental/PeytonviIle, Continental/Davis, White Chapel/Dove and Carroll/Southlake Boulevard) were identified as candidates for further engineering evaluation for Phase 3. Phase 3 deliverables will provide the fundamental elements necessary to start pre-project planning activities essential to developing capital projects. The deliverables from this project will include (for all 5 intersections): Task 1: Topographic and Boundary surveys Task 2: Conceptual layout Task 3: Coordination Meetings Task 4: Supplemental Subsurface Utility Exploration Financial Considerations: Funding for this Phase of the Intersection Capacity Analysis is included in the FY18 Capital Improvement Program (CIP) Budget. Strategic Link: The Intersection Analyses project and phases link to the City's strategy map relative to focus areas of Infrastructure, Mobility and Quality Development. The specific corporate objectives that are met by this mobility project are (C2) to provide travel convenience within the City & region and (F2) to invest to provide and maintain 4L high quality public assets. The critical business outcome is to (C13O2) enhance mobility through aggressive traffic management initiatives and capital project implementation. Citizen Input/ Board Review: N/A Legal Review: This is a standard Engineering Services Agreement that has been previously reviewed by the City Attorney. Alternatives: The Council may approve the Engineering Services Agreement or deny it. Supporting Documents: Engineering Services Agreement Staff Recommendation: Approve Engineering Services Agreement with Kimley-Horn and Associates, Inc. for Various Intersection Analyses Citywide — Phase 3 an amount not to exceed $130,000.

(the "ENGINEER") is pleased to submit Attachment A of the Agreement for Engineering Services to the City of Southlake (the "CITY")for providing professional services to perform conceptual-level design services for various City intersections. Our Scope of Services, Schedule, and Fee and Billing are set forth below. Project Understanding Based on previous studies by the ENGINEER performed under a separate agreement and discussions with the CITY, the CITY has requested the ENGINEER to provide conceptual-level design, TxDOT coordination and associated opinions of probable construction costs (OPCCs)for intersection improvements at the below intersections: • Southlake Boulevard (FM 1709) and Carroll Avenue • Dove Road and White Chapel Boulevard • Continental Boulevard and Davis Avenue (FM 1938) • Continental Boulevard and Peytonville Avenue • Continental Boulevard and Byron Nelson Parkway Scope of Services Task 1— Topographic and Boundary Survey The ENGINEER(through a Subconsultant)will perform full topographic survey for the limits of the proposed improvements. The following items will be performed: • Limits will include the following: o The following intersections plus 200 linear feet along all intersection legs: ■ Southlake Boulevard (FM 1709) and Carroll Avenue (600' along FM 1709 intersection legs) ■ Dove Road and White Chapel Boulevard ■ Continental Boulevard and Davis Avenue (FM 1938) ■ Continental Boulevard and Peytonville Avenue ■ Continental Boulevard and Byron Nelson Parkway • Data Collection and Property Research o Gather existing plat information o Collect property owner information o Gather existing right-of-way and easement information based on available plats and record drawings. Title research, if required by the CITY, can be provided as an Additional Service • Perform field survey ground control • Locate pertinent objects and above-ground features, typically including: o Roadway pavement o Drainage structures (i.e. culverts, ditches, inlets, manholes, and outfalls) kimley-horn.com 2201 West -. 75063 .�� Kimley>>> Horn Page 2 o Utilities (signs or markers showing the presence of underground utilities, valves, manholes, flowlines, meters, backflow preventers, vents, poles, and guy wires) o Large (6 inch diameter and up), significant trees (identify species and caliper) o Limits of landscaped areas will be defined. Individual plants and or trees (less than 6 inch diameter) will not be located. o Fences (including material type) and gates o Sidewalks o Street lights o Signs o Right-of-Way monumentation • Process survey data to create plan view of existing features • Prepare a final topographic drawing in digital format (including contours and break lines) showing the features located in the field as well as right-of-way information, an ASCII coordinate file of the points located in the field, and a hard copy of the coordinates and feature descriptions. Digital files will be in .DWG format. The ENGINEER will conduct one site visit to field verify the topographic survey Task 2— Conceptual Layouts The ENGINEER will prepare plan view layouts of the five aforementioned intersections at a 1"=40' or larger scale with an aerial background. The layouts will show conceptual proposed curb geometry, existing and proposed traffic lane usage, callouts highlighting potential (known) conflicts, anticipated limits of right-of-way acquisition, and improvements needed to widen the approaches and departures (if necessary) of each intersection. Improvements recommended in the Citywide Intersection Analysis provided to the CITY by the ENGINEER will be shown on the layout. Improvements are anticipated to include the following: • Southlake Boulevard (FM 1709) and Carroll Avenue o Widen intersection to the north to construct dual eastbound and westbound left turn bays o Extend southbound right turn bay by lane shift option (currently under design by ENGINEER) o Reconstruct curb ramps (8) to be two-directional and aligned with crosswalks o Traffic signal modifications including: ■ Traffic signal pole relocations and/or replacements ■ Signal head modifications/additions as needed ■ Adding pedestrian poles where needed ■ Updating push buttons to APS for all corners • Dove Road and White Chapel Boulevard o Reconstruct the existing single-lane roundabout as a dual-lane roundabout • Continental Boulevard and Davis Avenue (FM 1938) o Construct a right turn bay at the northbound approach o Construct right turn bay for the eastbound approach o Realign eastbound approach and construct second westbound left turn bay o Extend westbound turn bay past first driveway o Reconstruct curb ramps (8) to be two-directional and aligned with crosswalks o Restripe crosswalks and stop bars to align with new curb ramps o Traffic signal modifications including: ■ Traffic signal pole relocations and/or replacements ■ Signal head modifications/additions as needed ■ Adding pedestrian poles where needed ■ Updating push buttons to APS for all corners kimley-horn.com 2201 West -. 75063 .�� Kimley>>> Horn Page 3 • Continental Boulevard and Peytonville Avenue o Reconstruct the stop-controlled intersection as a single-lane roundabout • Continental Boulevard and Byron Nelson Parkway o Reconstruct the stop-controlled intersection as a dual-lane roundabout • After CITY review of the conceptual layouts, ENGINEER will prepare opinion of probable construction costs (OPCCs)for each intersection • Deliverables will include two (2) full-size color plots of each of the conceptual layouts, hard copies of the OPCCs, and digital files of all the documents prepared • The ENGINEER will respond to one (1) round of CITY comments on the conceptual layouts and OPCCs Task 3— Coordination and Meetings ENGINEER may meet with TxDOT and/or CITY staff, as directed by the CITY, on an hourly basis. This task assumes up to forty (40) hours of ENGINEER's attendance at meetings, including City Council meetings. Additional meetings beyond this amount can be provided as additional services.
