DELIVERABLES: Preliminary Design Report TASK 3 — DEVELOP 30% PLANS, SPECIFICATIONS AND ESTIMATES (PS&E) [TASK DURATION: 12 WEEKS] TASK 3.1— PREPARATION OF 30% DESIGN PLANS/ CONSTRUCTION DOCUMENTS The Terraphase Team will advance the preferred alternative to develop design materials representing 30% Project definition, consisting of grading plans, landscape drawings, utility and design drawings and details. All plan drawings, details and sections will be developed in digital format using AutoCAD. Kelly Lam will serve as lead CAD designer under the supervision of Hans Kramer, Lucas Paz, Scott Wallace, and Jeff Raines. The Terraphase Team will develop grading plans showing plan and profile of the proposed treatment wetland and embankments, utility alignments, and detailed construction sections. Re -vegetation plans and associated landscape drawings and details will also be developed for selected areas in the Project site. The landscaping design will involve development of a customized plant palette and planting plan for the site to support hand -planting of native species, to be developed with expert input. The customized planting plan and an approved list of recommended native plant species for the Project will be developed by our landscaping expert, Megan Stromberg (professional landscape architect and wetland revegetation specialist), detailing areal placement of plant installations and seeding specifications for the respective Project area to address both the wetland treatment and habitat creation objectives. Terraphase will prepare a preliminary list of drawings to be prepared to illustrate the basic scope and approach prior to producing the 30% plan set. Drawings will be prepared in AutoCAD, following agreed-upon drafting standards. We will provide design drafts provided to the City for review and comment, incorporating City feedback into the design documents prior to presentation. The Terraphase Team will also prepare and conduct presentations to review the draft design documents with Project proponents, at which point stakeholder consultation and feedback will be garnered. Drafts will be provided at least fourteen days prior to corresponding presentations. Terraphase will incorporate feedback from Project stakeholders into subsequent drafts and materials. The Terraphase Team will produce the completed 30% design with corresponding visual exhibits and present to Project proponents, other stakeholders, and/or regulators, at up to two meetings, to inform next steps for the Project.
