In order to standardize the construction and record drawings, the following set of guidelines were developed to make all plans or drawings uniform. The guidelines are to be adhered to insofar as they are practical, but may be altered by the Platting Officer depending upon the project.
(A) General requirements.
(1) Incorporated in the set of plans shall be a sheet indicating the entire project with corresponding sheet numbers on each separate sheet and index.
(2) All record plans are to be mylar sepias from inked and clearly legible drawings with unnecessary construction information removed.
(3) All sheets are to be 22 x 34.
(4) Scale: horizontal scale- 1 inch = 50 feet; vertical scale- 1 inch = 10 feet.
(5) The following are preferred locations for utilities:
(a) Sanitary sewer: On center line of street right-of-way or easement.
(b) Watermain: When the watermain is to be placed at the same level as the sewer line, 10 feet north or west of the street right-of-way or easement centerline. When the watermain will be at least 18 inches in elevation above the sanitary sewer, the watermain are to be shown 5 feet west or north of the street right-of-way or easement centerline.
(c) Storm sewer: On the south or east side of street right-of-way or center line of easement.
(6) A title block in the lower right corner of each plan sheet indicating project description and sheet information clearly labeled.
(7) Construction details are to be on one separate plan sheet and referenced to the proper sheet or combined in one section in the specifications.
(8) The profile is to be directly below the plan with the stationing aligned as closely as practical. Stationing is to be shown on the plan view as well as the profile.
(9) All parcels are to be properly labeled with lot and block numbers and plat name, or parcel number in unplatted areas. Developed parcels are to have their address shown on the plan.
(10) All streets are to be clearly labeled.
(11) All match-line breaks are to be clean with reference points clearly marked. All plans which are broken by a match-line are to be on the same or consecutive sheets.
(12) Existing utilities are to be shown, stationed, and labeled as existing.
(13) Approximate locations of gas, electric and telephone lines are to be shown.
(14) Right-of-way and pavement or curb and gutter alignment data are to be shown.
(15) All plans are to have properly placed north arrows and bar scale (graphic scale) for each plan on the sheet.
(16) Bench marks are to be placed on all sheets.
(B) Specific requirements.
(1) Stationing of sanitary sewer wyes are to be indicated as in front of the stationing.
(2) All sanitary services are to be drawn on the plan to the constructed length and length noted. Indicated if jacked.
(3) If sanitary sewer wye only is constructed, it is to be noted as wye only after the stationing.
(4) The approximate invert elevation of all sanitary sewer services are to be shown on the plans. If risers are placed, the height of each is to be indicated on the plans and each are to be drawn on the profile, and indicate height of risers.
(5) All manholes are to be numbered in both plan and profile.
(6) All hydrants are to be stationed on the bottom of the profile.
(7) Stationing of water corporation cock is to be indicated by “w” in front of stationing.
(8) All water services are to be drawn to constructed length and length noted if other than to property line. Indicate if jacked.
(9) All gate valves are to be tied with at least two ties using the following priority:
(a) Fire hydrants;
(b) Manholes;
(c) Catch basins, if curb and gutter is installed;
(d) Buildings or other permanent structures;
(e) Power poles, trees, other semi-permanent items;
(f) Stationing from hydrants, manholes, catch basins, if over 100 feet.
(10) The size and type of all sanitary sewer and water services are to be noted on the plans.
(11) On combination sewer and water projects, services may be placed in the same trench with sanitary sewer services three feet downstream from water services. This shall be noted on the plans and “s & w” are to be placed before the stationing.
(12) All services are to be tied with at least two ties using the following priority:
(a) The served structure with address noted;
(b) Neighboring structures with address noted;
(c) Fire hydrants;
(d) Manholes, catch basins, if curb and gutter is installed;
(e) Other permanent structures, bridges, and the like;
(f) Power poles, trees, other semi-permanent items;
(g) Stationing from hydrant, manhole, catch basins. These may be used with back of curb distance.
(13) All sewer and watermains are to be shown in profile with the appropriate information such as size, material, grades, invert elevations, and the like. Watermain profiles may be omitted if watermain is in existing or proposed street, if the street grade is indicated, and if the depth is noted.
