Two complete sets of construction plans and specifications shall be submitted to the City Engineer for review prior to contracting for construction of improvements. The plans shall be prepared on plan/profile sheets, or plan sheets with separate profile sheets, which are 36 inches wide and 22 or 24 inches high with a binding margin of not less than 1-1/2 inches on the left side of the sheet. Profiles shall have grid increments of not less 1/10 inch. The plans shall be drawn to a scale of 20 feet to the inch horizontally and five feet to the inch vertically. The plans must also be furnished in AutoCAD Release 11/12, AutoCAD 2000, Microstation or standard ".dxf' format as approved by the city.
(A) Complete plans shall include the following sheets:
(1) Title sheet showing names of subdivision, subdivider, Engineer, City Engineer, City Manager, date, location map, and any other pertinent information. It should also provide a space for signature of approval from the City Manager and City Engineer.
(2) Preliminary plan as submitted and approved.
(3) Overall water and sanitary sewer layout sheet showing street, layout, lots and lot dimensions, curve data, and any other pertinent information necessary for surveying all lots and streets. This may be a modified print of the subdivision preliminary plan.
(4) Drainage area map, drainage study and drainage computation sheet showing contours at minimum ten-foot intervals for the entire drainage basin of all structures planned for the subdivision and flood plains shown on the plan. See § 154.34(B) of this chapter for further details.
(a) Right-of-way, lot lines, lot numbers, easements, subdivision lines, and city limit lines;
(b) Existing topographic features such as utility poles, fire hydrants, streets, driveways, lakes, watercourses, etc.;
(c) Existing underground utilities located as accurately as possible on both the plan and profile sections;
(d) Existing ground profiles along the centerline of proposed water and sewer improvements, at each proposed curb line and at each right-of-way line for street improvements;
(e) Survey baseline showing stationing and appropriate information to re-establish baseline, if necessary;
(f) Street names, north arrow and graphic scale;
(g) Benchmark (National Geodetic Survey Datum, formerly U.S. Coast and Geodetic Survey Datum) description and elevation on each sheet with temporary benchmarks set at intervals of not more than 600 feet;
(h) Location of soil borings;
(i) Proposed streets, storm sewer, sanitary sewer, water, electrical, gas, T.V. cable lines and telephone lines, including valves, fire hydrants, water and sewer service lines, manholes and cleanouts;
(j) Stationing of proposed improvements to left or right of the survey baseline, and angles and stationing of intersection streets;
(k) Curb radii, and special curb grade points such as end of radius returns and mid-points and top of inlet, etc.; limits of significant cut or fill; directional arrows showing direction of drainage in gutters; and crown transition in intersections;
(l) Proposed top of curb profile line and existing top of curb line where curb has previously been built. If the new street does not have curb and gutter, proposed top of pavement profile along centerline and flowline of ditches on both sides;
(m) Horizontal and vertical curve data including the curve length, vertical point of intersection station and elevation, and high point or low point station and elevation. Percent grades shall be shown on all tangents.
(n) Top of curb elevations shall be shown at not more than 50-foot intervals in tangents, and 25-foot intervals in vertical curves. The PC, PT and PI shall be shown in profile with station and elevation;
(o) Proposed flowline of sanitary sewer mains, storm sewer, culverts, channels and water mains. Percent grades shall be shown between manholes and/or cleanouts on sewer lines. Flowline elevations shall be shown at not more than 50-foot intervals. Top and flowline elevations shall be shown for all manholes and cleanouts for sewer lines, channels, inlets, manholes and headwalls for storm sewer lines, and for all valves, air release or blow-off structures for water mains 12 inches and larger;
(p) Minimum finished floor elevation for each lot within or adjacent to a 100-year floodplain or drainage easement, or where a lot requires fill for sanitary sewer service;
(q) Special notes;
(r) Engineer's seal and signature on each sheet.
(B) One set of plans and specifications marked with any changes required by the City Engineer will be returned to the subdivider or his or her authorized representative. One corrected set of plans and specifications plus the original title sheet shall be submitted to the City Engineer for approval. The original title sheet will be returned, upon approval and signature by the City Manager and City Engineer. Five complete sets of the approved plans and specifications shall be submitted to the City Engineer prior to start of construction.
(C) Within 30 days after written final acceptance of all improvements, one set of mylar film originals or mylar film sepias of the "As Built" or "Record" plans shall be submitted to the City Engineer. The plans shall show the location of all lines, valves, fire hydrants, manholes, cleanouts, service connections, curb lines, inlets and storm sewers, and the installed alignment and grades. All valves, manholes, cleanouts and service connections shall be located on the ground, tied to at least two permanent land marks that are at least 90 degrees apart, i.e. fire hydrants, power poles, property corners, etc.
