Specifications include, but are not limited to: Task 1: Survey Survey from the northbound outer lane to the east side of Glenridge Drive within project limits. Include lane striping, signages, drainage systems, walls, fence, structures, Hammond Park parking lot curbs and striping, trees at least 10” DBH including species in the survey. A current and accurate ground run (2’ contour interval) topographic survey of the entire project area will be required. Survey shall include local issuing authority requirements for setbacks, zoning, buffers, surrounding land use and zonings, and Fulton County GIS benchmark reference. A Topographical Survey was done of Hammond Park for the City. The survey data is available to the Consultant. All utilities are to be located to SUE Level B. Level A SUE (assume 15 test holes) will be added to the project as required. Task 2: Concept Design The Consultant will be responsible for the following tasks during the concept design phase of the project: • Concept Design: Provide a concept design that delivers a twelve (12) foot wide sidepath with six (6) foot grass/landscape strip and minimum one (1) foot back of sidepath buffer per COSS Technical Manual on the east side of Glenridge Drive from Hammond Drive to 5795 Glenridge Drive. Due to the parking lot layout and topography at Hammond Park, two concept designs are required for the sidepath along the Hammond Park frontage. Crosswalks and ADA ramps are required at appropriate locations. Ensure Americans with Disability Act (ADA) standards are addressed and appropriate design features are incorporated. It is a City preference not to use guardrail while still providing an appropriate roadway clear zone. Concept designs should balance this preference with the other design constraints/policies cited herein. The Consultant should also prepare a hydrology study for the road including analysis of gutter spread and provide design of a storm drainage system, as needed. Approval of concept drawings with any associated redline comments is required (in writing) prior to commencement of preliminary design documents. • Tree Protection: Provide tree protection plan per COSS Technical Manual. Identification and protection (where possible) of existing significant trees. Coordination and recommendations with the City Arborist is anticipated. Restoration of landscape buffer where removal of existing trees is required to construct the sidewalk. The services of a registered Landscape Architect are expected to provide this project design support. • Green Infrastructure Feasibility Study: A Green Infrastructure feasibility study is required per City Code for transportation projects. It is anticipated that the project is exempt for Green Infrastructure Analysis and will not be feasible for Green Infrastructure design. • Utility Coordination: The Consultant will coordinate with all applicable utility companies to obtain details of facility locations, identify any conflicts, and incorporate necessary utility relocations/redesigns into the plans. This effort will also include attending and participating in the City’s monthly utility coordination meeting. All utilities are to be located to SUE Level B and incorporated into the Concept Design. A proposed utility plan with a first utility submission to all utility providers is anticipated as part of the preliminary design. A utility coordination log will need to be created and maintained. • ROW Plans: The Consultant should be prepared to provide ROW plans that clearly summarize the locations and amounts of any easements and/or right of way acquisitions that will be required to construct the project. It is the intent of the City to minimize the requirement for additional right of way and associated easements from adjacent property owners. • Retaining Wall Design: Given the existing site characteristics, retaining walls will be required. The consultant will be required to have structural engineering support to prepare any necessary wall designs and the structural engineer should advise the design during concept phase on wall requirements. Wall foundation investigations through a geotechnical engineering consultant may be required depending upon the nature of the required walls. • Pedestrian Light Design: Pedestrian and street lighting is required by City Code. It is the City’s intention to lease these lights from Georgia Power. The Consultant shall lay out the light locations along the corridor per PCID standards. • Field Plan Review: Coordinate concept field plan review. • City Approval Process: The Consultant will be required to obtain approval of the plans from the City’s Public Works (PW) Department. During the Concept Phase, this will include submitting concept level plans to COSS PW for review and approval. The Consultant will submit a design exception package detailing any variances from the City’s standards for approval by PW.
