WEBB ASSOCIATES FOR ENGINEERING DESIGN SERVICES FOR THE MEASURE J COMMUNITY HOT SPOTS PROJECTS, CITY PROJECT NO. 15-31 FROM: David H. Ready, City Manager BY: Engineering Services Department SUMMARY Approval of this action will authorize additional civil engineering design services associated with the Measure J Community Hot Spots Project, City Project No. 15-31. RECOMMENDATION: 1) Authorize an increase in the amount of $24,900 to Purchase Order No. 16-1088 with Albert A. Webb Associates for a revised total amount of $212,800 for the Measure J Community Hot Spots Project, City Project No. 15-31 ; and 2) Authorize the City Manager to execute all necessary documents. BACKGROUND: On May 4, 2016, the City Council approved a purchase order in the amount of $187,900 with Albert A. Webb Associates to design gap closure sidewalks at various locations throughout the City for the Measure J Community Hot Spots Project, City Project No. 15- 31. During the plan preparation process, several unanticipated challenges and complexities, listed below, were discovered that necessitates additional civil engineering and traffic engineering design services. • Required modification of existing traffic signals to accommodate ADA. ' I ITEM NO. — City Council Staff Report April 5, 2017-- Page 2 Increase PO 16-1088, CP15-31 • Signing and Striping plans required for roadway alignment affected by sidewalk location. • Alternate design scenarios for the proposed sidewalk at Sunny Dunes Road within the business district. • Alternate design scenarios on Baristo Road where the curbs heights are not typical due to the intent of the roadway to act as a drainage channel. • Additional field surveying and design services to reconstruct existing driveways for ADA compliance. The revised design cost is well within the industry standard of 15% of the estimated construction cost ($2,153,000), therefore, staff recommends that City Council authorize an increase in the amount of $24,900 for a revised total contract amount of $212,800 for Purchase Order No. 16-1088 with Albert A. Webb Associates. A copy of change order proposal from Albert A Webb Associates is included as Attachment 1. ENVIRONMENTAL IMPACT: Section 21084 of the California Public Resources Code requires Guidelines for Implementation of the California Environmental Quality Act (CEQA). The Guidelines are required to include a list of classes of projects which have been determined not to have a significant effect on the environment and which are exempt from the provisions of CEQA. In response to that mandate, the Secretary for Resources identified classes of projects that do not have a significant effect on the environment, and are declared to be categorically exempt from the requirement for the preparation of environmental documents. In accordance with Section 15301 "Existing Facilities," Class 1 projects consist of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing highways and streets, sidewalks, gutters, bicycle and pedestrian trails, and similar facilities. Therefore, in accordance with Section 15301(c), the Measure J Community Hot Spots Project, City Project No. 15-31, is considered categorically exempt from CEQA, and a Notice of Exemption was prepared and filed with the Riverside County Clerk. FISCAL IMPACT: Sufficient funds are budgeted and available in the Measure J Project Fund; Account No. 260-4494-58702 to facilitate approval of increase in the amount of $24,900 for the Purchase Order increase for Albert A. Webb Associates for the Measure J Community Hot Spots Project, City Project No. 15-31. 02 City Council Staff Report April 5, 2017-- Page 3 Increase PO 16-1088, CP15-31 SUBMITTED: Marcus L.

The curb return is to be reconstructed in its ultimate location which necessitates a modification to the existing traffic signal. This will require moving two existing traffic signal poles and signal equipment. New pavement construction along two segments of Indian Canyon Drive is necessary to place sidewalk in its ultimate location. Indian Canyon Drive south of San Rafael Drive and Indian Canyon Drive south of Racquet Club Road require it. In doing so, the existing pavement on Indian Canyon Drive will undergo grind and overlay treatment to provide a smooth travel surface. Existing striping will be removed in the process. Striping plans for both project areas can be designed to replace and/or improve striping. Also, two current project areas on Sunny Dunes Road and Baristo Road contained obstructions that would block or greatly change the typical path of travel of a new sidewalk. WEBB is proposing to provide two alternatives for each project area regarding sidewalk location and path of travel. The City can then decide which option is preferred and design on the two segments can continue. During the plan preparation and review process, it was determined that additional field topography for existing driveways onto the private properties and design necessary to make project fully ADA-compliant. WEBB proposes the additional scope of work as shown in Exhibit "B" and compensation as shown in Exhibit "C". 06 Exhibit "B" - Scope of Work A.
