LANG RANCH CDNMUNFIY PARK DESIGN DEVELOPMENT AND CONSTRUCTION Docui' iEr\,rs Scope of Servs l es P S Q M A S QUALITY AssmzM&Qu L= Co�rmm — Psomas will provide a thorough in-house review of all improvement plans prepared at the design development stage of the project. The design and accuracy of all plans will (continued) be verified and any necessary revisions or corrections will be incorporated into the plans prior to presentation to the District. Construction Document Services P S 0 M A S Based on the plans and documents prepared by the Project Team at the design development stage of the project, input received from the District, the City of Thousand Oaks and the Citizen's Design Review Panel, Psomas will prepare the following construction documents; HvDRoLooY STUDY — Psomas will prepare a hydrology study to determine existing and proposed flows to be used in sizing proposed on-site drainage systems. The hydrology study will determine the amount of flow that mast be detained on-site to ensure that the post -development flows do not exceed the pre -development flows based on the requirements of the Ventura County Watershed Protection District. Stormwater flows will be determined where necessary for sizing on on-site pipes, drainage structures and detention facilities. RouGH GRADrnrG PLAN — A 50 -scale rough grading plan will be prepared based on the preliminary design provided above and input received during the design development phase of the project. The rough grading plan will incorporate all grading recommendations provided by the Geotechnical Consultant and will be processed for approval with the City of Thousand Oaks. Our goal will be to provide a rough grading plan that provides a site matching the approved Master Plan while maintaining balanced earthwork. Fm GRADwo AND DRAINAGE PLAN — Psomas will provide a 20 -scale fine grading and drainage plan that incorporates the horizontal layout of the final landscape and hardscape design, the final sports fields and courts design and the final building design. We will include finished grades, finished surfaces, flowline elevations, driveway and parking lot grades, all drainage structures including sizes and specifications, all drainage, sewer and water lines including connection points and outlet locations. HoRmoNTAL COWROL PLAN — PSomaS will prepare a 20 -scale horizontal control plan that provides the horizontal layout of all proposed on- site improvements. Included will be horizontal ties that will allow for construction survey of the proposed project improvements. UTmrrY PLAN — Psomas will prepare an on-site utility plan that will provide the horizontal locations of storm drain, sewer and water lines. Plan will also provide connection points at the project boundary to be used by the Scope of Services - 22
