2.D.2 Plans and Drawings <br />Applications for a permit shall be accompanied by such drawings, surveys or plans as <br />deemed necessary by the City Engineer. EC 7.295 (2) <br />Generally, the permittee shall be required to supply two sets of complete and accurate <br />plans and/or drawings depicting the proposed facility installs#ion. Three copies will be <br />made to allow one each for the Utility Inspector, the office file of the permittee and the <br />permittee's field crew performing the work. <br />In those cases where the proposed work falls within the area of a current City improve- <br />ment project (subdivisions, sewer construction, street paving, etc.) four copies will be <br />made of the plans and/or drawings. The fourth set shall be forwarded to the .Engineering <br />Division Project Manager assigned to the City improvement project for placement in the <br />project office file. <br />All plans and/or drawings shall contain a north arrow. The proposed work area shall be <br />referenced by accurate dimensions to a known intersection center-point, lot corners or to a <br />known City manhole if an intersection center-point is not available. The plans and/or <br />drawings shall be to scale both vertically and horizontally and designate with accurate <br />dimensions the portion of the public way proposed to be used and the work zone within <br />the public way. The work zone shall be considered to include 10 feet at a minimum <br />around the perimeter of the proposed excavation or facility placement and shall include <br />staging and material storage areas within the public way. The plans shall show accurate <br />locations of curbs, sidewalks and driveways within the proposed work zone. <br />If the critical root zone of a street tree is located within the proposed work zone, the <br />applicant shall so indicate on.the permit application, and the plans shall accurately depict <br />the areas of the work zone which may impact street trees, along with the size and .location <br />of each tree within such areas. The critical root zone for trees 3 inches or smaller in <br />caliper shall be an area with a radius of at least 3 feet from the trunk. The critical root <br />zone for trees over 3 inches in caliper shall be an area with a radius of at least eighteen <br />inches from the trunk for every 1 inch of caliper size. <br />If the work zone or portions thereof are outside the public right-of--way but within a public <br />utility easement, the plans shall show any locations where the work zone falls within <br />natural resource protection areas (e.g. wetlands, rare plant areas, conservation zones, <br />individual trees designated for protection, etc.). <br />2.D.3 Review <br />Before each permit is issued, the applicant's plans are evaluated by the staff of the City <br />Engineer. Engineering Division personnel draft the location and size of all known City- <br />owned facilities, for which records are on file at the Engineering Division (e.g. storm and <br />sanitary sewers, telecommunications, curbs, etc.), on each set of .the plans provided by <br />the permittee of the proposed facility. Engineering staff also evaluate the permittee's <br />proposed installation in relation to planned future City facility placements for conflicts with <br />Utili#y & R/W Permit Policy 10 06/01/97, <br />
