(e) EPA water construction permits.
(f) Two copies of the storm sewer calculations.
(g) Two copies of the storm drainage plan.
(h) Two copies of the retention facility calculations.
(i) Two copies of the hydraulic gradient profiles of the storm sewer design, if the design is based on the hydraulic gradient.
(j) Two copies of the engineer's estimate of cost.
(k) Two copies of the water main calculations for consumption and fire flow demand when the design is less than the minimum design required by this chapter.
(l) Two copies of the pavement thickness design calculations.
(2) Engineering plans. The engineering drawings, which are submitted, must include the following information:
(a) A title sheet showing the name of the project, section, township and range, an index of sheets, a tabulation of symbols, location of benchmarks and a graphic location with respect to nearest traveled streets and roads.
(b) General plan layout of the project indicating all requirements.
(c) A detailed grading plan indicating the elevations of all building foundations, lot corners, and points of change in gradient.
1. Direction of flow of surface waters will be delineated with arrows and the gradient of the land indicated above the arrows.
2. Curb elevation will be indicated opposite each lot corner and all changes in gradient.
(d) A detailed plan of street improvements showing horizontal and vertical locations of all street and sidewalk improvements and including horizontal and vertical locations of all points of tangency, points of vertical curvature, points of vertical intersection, and points of vertical tangency. Radii of intersection of streets will be shown on this plan.
(e) A detailed plan of storm sewer improvements showing horizontal and vertical locations of all manholes, catch basins, inlets, headwalls, and the like and indicating lengths, types and grades, and gradients of all storm sewers and swales meeting all requirements of the village adopted Will County Stormwater Ordinance.
(f) A detailed plan of sanitary sewer improvements showing horizontal and vertical locations of all manholes and indicating lengths, type and grade, and gradients of sanitary sewers.
(g) A detailed plan of water system improvements indicating horizontal and vertical location of all fire hydrants and valves and showing lengths, sizes, and locations of all water mains.
(h) Plans and profiles drawn at a scale not to exceed 1 inch equals 40 feet horizontally and 1 inch to 10 feet vertically indicating additional horizontal and vertical locations of streets, sewers, appurtenances, and the existing grade.
(i) Such additional details as are necessary to clarify the extent or manner of construction.
(j) Summary of all quantities.
(k) An erosion and sedimentation control plan, along with the required SWPPP EPA Permit.
(l) General detail sheets showing:
1. Pavement cross section.
2. Curb, gutter, and sidewalk details.
3. Cross section of detention facilities including sedimentation basins.
4. Manholes, vaults, inlets and castings.
5. Hydrants.
6. Typical trench cross sections for sanitary sewer, storm sewer, and water mains.
(B) Requirements for installation of improvements.
(1) (a) Prior to the approval of the final plat of the proposed subdivision or planned development by the Village Board and prior to the recording of the plat, appropriate bonds, escrow monies, recapture fees, irrevocable letters of credit for public improvements, and any other related fees must be deposited with the Zoning Administrator.
(b) When the appropriate subdivision improvement security is posted and all permit fees paid to the village, the installation of the required improvements may begin.
(2) Development engineering review fees shall comply with the village's current professional fee reimbursement agreement.
(C) Inspections.
(1) All improvements constructed under the terms of this chapter shall be subject to periodic inspections by Village Engineer.
(2) The fees for such inspections shall be payable in accordance with the provisions of the professional fee reimbursement agreement and the then current fee schedule approved by the Village Board from time to time.
