(A) Generally.
(1) Prior to final approval, the subdivider shall have installed or furnished surety, in accordance with § 152.101, to guarantee the installation of the improvements hereinafter required.
(2) All items of work covered and stipulated in the improvement plans, including altering or any extra work, shall be performed in accordance with the lines, grades, typical cross sections and dimensions shown on the construction plans. All areas within the rights-of-way and easements shall be graded in accordance with the grading plan. All other areas shall be rough graded such that building construction, including basement excavation, will satisfy final grading in accordance with the grading plan. The setting and marking of all lines, profile, and grade stakes necessary for the layout of the work in accordance with the improvement plans will be performed under the supervision of a registered engineer or registered surveyor. Should any misunderstanding arise as to the intent or meaning of the construction plans, or any discrepancy appear in same, or in the proper method of setting and marking of the construction stakes, the decision of the Village Engineer in such cases shall be final.
(B) Village construction and material specifications. The construction material specifications of the state’s Department of Transportation, latest edition, and the village standard drawings and specifications shall govern the required improvements except as modified within these subdivision regulations.
(C) General requirements.
(1) All improvement plans shall be prepared, signed, and sealed by a registered professional engineer. Plans shall include title sheet, index map, location map, typical sections, plan and profile view, bench marks, miscellaneous engineering details, and estimate of quantities. Cross sections shall be submitted upon request by the Village Engineer. All typical sections and major engineering details to be used on any particular street shall be approved in advance before completion of the improvement plans. Scale of improvement plans shall be one inch = 40 feet horizontal and one inch = five feet vertical.
(2) The title sheet of the improvement plans must contain the name of the subdivision, road or street names, county, and location map. Space shall be provided on the title sheet or the first sheet of the plan for signature of the Village Engineer and Village Manager.
(3) The necessity of guard rail, seeding, erosion control, type of backfill, or other special conditions shall be determined with the assistance of the Village Engineer before completion of the improvement plans.
(4) The improvement plans shall show the drainage area and design flow for all major culverts.
(5) The construction plans shall be made with India ink on matte Mylar material. Freehand linear drawings will not be accepted. No shading or coloring shall be allowed. The sheets upon which the construction drawings are made shall measure 24 inches by 36 inches, with one-half inch margin border on three sides and a one and one-half inch to two-inch binding margin on the short left side. A poorly drawn or illegible plan is sufficient cause for rejection.
(6) Submittal requirements include improvement plans, sanitary sewer calculations, storm drainage calculations, grading plans, landscaping plans, erosion and sedimentation control plans, and lighting plans. See § 152.028 for time frames for submittal to the Director in conformance with policy established with the Planning Commission.
(7) Re-submittal of improvement plans shall clearly show all revisions made thereto, by dated notes in the “revision” block and outlines of the revisions.
(8) After the improvements have been constructed, a complete set of as built plans on reproducible Mylar and magnetic data files in a format compatible with village mapping systems shall be submitted to the Village Manager for village files.
(D) Improvement plans.
(1) Plan view on improvement plans must include the following:
(a) Right-of-way line, centerline, departing lot lines, lot numbers, subdivision limits, and limits of construction;
(b) Centerline curve data, including delta, radius, arc, chord, and tangent;
(c) Radius of all curb returns to face of curb;
(d) Approved street name, in accordance with § 152.067;
(e) Stations at every 100 feet on centerline. Indicate stations at points of curve and tangent at the beginning and end of all returns at centerline intersection, and at subdivision or section limits;
(f) The back of curb for full length of all streets;
(g) When proposed streets intersect with or join existing streets or traveled way, indicate both edges of existing pavement, surface, or curb and gutter for a minimum of 100 feet, or the length of connection, whichever is the greater distance;
(h) All existing or proposed easements;
(i) All water mains, their sizes, valves, and fire hydrants, and location of mains to centerline of street;
(j) All storm sewers and appurtenances. Identify storm sewer appurtenances by type. All appurtenances shall be numbered. Indicate the top elevation of each structure. Storm sewer appurtenances and locations should be referenced to the centerline station of street;
(k) All sanitary sewers and appurtenances. Identify sanitary sewer appurtenances by type. All appurtenances shall be numbered;
(l) The location of all or any natural springs whether within or draining to street right-of- way and indicate proposed treatment of same. All springs will be capped and piped in a minimum six- inch diameter perforated pipe encased in washed gravel, and connected into the nearest storm manhole or curb inlet;
(m) Proposed stream or channel relocations. Show existing and proposed locations. Furnish detailed typical section and type of stabilization to be provided;
(n) Guard posts or barricade at the end of streets which are to be extended in the future. A temporary T-turnaround shall be provided for dead-end streets exceeding 200 feet in length;
(o) Protection of ends of curb and gutter by providing for erosion control and temporary drainage where required;
(p) Where a special typical section is approved, provide detail on plan;
(q) Notes that may be necessary to explain the intent and purposes of the plan;
(r) Symmetrical transition of pavement at intersection with existing street; and
(s) Proposed construction traffic entrance.
(2) Profile view on improvement plans must include the following:
(a) Elevations at beginning and end of all vertical curves;
(b) Length of vertical curves with elevations and stations of vertical points of intersections (VPI);
(c) Elevations computed every 50 feet on all tangent sections, and grades computed every 25 feet in all vertical curves;
(d) Elevations along all curbs and curb returns on intersecting streets. The grades of intersecting streets shall match at the intersection of the extensions of the respective curbs. In other words, a hypothetical curb P.I. must be established;
(e) Elevations at all curb inlets;
(f) Extension of centerline profile 300 feet beyond property line or boundary on all streets that provide for access to adjoining property;
(g) Existing centerline profiles for 200 feet minimum distance to ensure proper grade tie, when proposed street is an extension of, or connects with an existing street or road;
(h) Centerline profile of existing street or road 300 feet minimum distance to right and left of proposed connection, when a proposed street intersects with an existing street or road;
(i) All proposed water mains, storm sewers, and appurtenances;
(j) All crossings of existing utilities; and
(k) Notes that may be necessary to explain the intent and purposes of the profile.
