Plan & Profife:The Joint Treneh Plan & Profile will be at 1"=20' scale, with 1"=10' enfargements at key <br /> locations. Plan & Profile sheets at 1"=20 scale will result in approximately 22 sheets, including side <br /> streets. loint Trench details will be initiated for the 65% submittal but not completed until the 95% <br /> submittal. The 65% plans will show the joint trench pr4file but will not have detailed callouts to avoid <br /> extra eff�rt as the profile is adjusted for the 95%submittal. Existing utilities are shown on the ptan view <br /> based on the utility field mapping performed under a separate agreement. The profiles of the existing <br /> utilities will be focused on the utilities adjacent to and crossing the joint trench. The gravity lines will be <br /> pro�led per the survey and the dry utilities/water lines wil! be profiled per the available record plans or <br /> documented assumptions. Many of the existing utilities witl be Shown in more detail on the 9596 prafiles <br /> as more mapping is obtained. Rotholing may be necessary per the Optional Services to determine the <br /> profi{es of unrecorded existing utitity crossings. The Form B information will be completed under a <br /> separate task described below and the Form 6 information will be entered onto a plan table in <br /> conjunction with typical$ections. <br /> P/an Enlarpements- Joint Trench Plan Enlargements of utility vauits and conduit congestion will be <br /> prepared for key locations as determined by the engineer as necessary to clearly define the work. The <br /> enlargements will show the proposed utility vaults/boxes, main joint trench, conduits sweeping in and <br /> out of new utility vaultsfboxes, limits of excavations, extent of curb and gutter removal and <br /> replacement,extent of sidewalk/driveway removal and replacement,and limits of demolition within the <br /> enlargement area and utility trench labelling for each segment within the enlargement area. <br /> Details: Cansultant will include details for joint trench equipment, including: PG&E #7 Vault, PG&E #5 <br /> Vault, PG&E #3 bvx, PG&E #2 box, PG&E #1 box, Comcast boxes, AT&T vaults and manholes, and <br /> Astound boxes.Additional details such as crossing over or under an existing utility wiil also be included. <br /> Trench backfill details will be included for a typical trench section ineluding surface restoration. Details <br /> will be started for the 65%submittal,but will not be complete at this stage. <br /> Minor UtiJitu Reloeations: During the design of the Jaint Trench it is anticipated there will be minor <br /> relacation af City wet utilities. �xampies of minor utility relocations are storm drain late�als, vertical <br /> offsets in water lines, sanitary sewer laterals, water meters and water services, �re laterals, fire <br /> hydrants, irrigation modifications at street crossings, street light and signal conduits. Design for <br /> relocation of main lines for water,sanitary sewer and storm mains are not anticipated to be included in <br /> this task. These existing utilities will be identified to be relocated privr to the installation of the joint <br /> trench. Tree trimming may also be included as an early site preparation work prior to Joint Trench. <br /> Surface R�storation:The Surface Restoration pians will include temporary curb relocations or temporary <br /> bulbouts to protect new utility vaults that are outside the existing sidewalk. These plans are not <br /> intended to show the future streetscape impravements, but the surface restoration will be coordinated <br /> with the City's Middlefiefd Road streetscape project. It is assumed that curb ramps and bult�outs will <br /> not be upgraded to current standards since the Middlefield Road Streetscape project will be current or <br /> immediately after the MUUD Project. Surface Restoration Plans will show the tempor�ry sidewalk, <br /> temporary curbs, temporary ramps and driveway replacements to City standards, restriping of street, <br /> tee trench sections for AC paving replacement,and median replacement at street crossings. <br /> Landscape & frripation: Replacement of park strip areas and median planting areas is expected to be <br /> limited and the design will avoid significant impacts to existing landscape. The median planting areas <br /> may be impacted at select joint trench street crossings south of Woodside Road. The basic services <br /> assume minor landscape restorations will be handled with civil constructian notes for bidding purposes. <br /> Also, the utility modification plans will have performance notes for reconnection of disturbed irrigation <br /> lines. Landscape architecture is included as an optional service if more extensive landscape and <br /> irrigation design is needed. <br /> REV:02-24-15 VR <br /> Page 13 of 20 <br /> ATTY/AGR.2015.037/Bellecci&Associates-Middlefield UUD <br />
