(a) Plan view on improvement plans must include the following:
(1) Right-of-way line, centerline, departing lot lines, lot numbers, subdivision limits, and limits of construction.
(2) Centerline curve data, including delta, radius, arc, chord, and tangent.
(3) Radius of all curb returns to face of curb.
(4) Approved street name.
(5) 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.
(6) The back of curb for full length of all streets.
(7) 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.
(8) All existing or proposed easements.
(9) All water mains, their sizes, valves, and fire hydrants, and location of mains to centerline of street.
(10) 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.
(11) All sanitary sewers and appurtenances. Identify sanitary sewer appurtenances by type. All appurtenances shall be numbered.
(12) 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 6-inch diameter perforated pipe encased in washed gravel, and connected into the nearest storm manhole or curb inlet.
(13) 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.
(14) Protection of ends of curb and gutter by providing for erosion control and temporary drainage where required.
(15) Where a special typical section is approved, provide detail on plan.
(16) Notes that may be necessary to explain the intent and purposes of the plan.
(17) Symmetrical transition of pavement at intersection with existing street.
(18) Existing structures within 200 feet of the proposed improvements.
(b) Profile view on improvement plans must include the following:
(1) Elevations at beginning and end of all vertical curves.
(2) Length of vertical curves with elevations and stations of vertical points of intersections (VPI).
(3) Elevations computed every 50 feet on all tangent sections, and grades computed every 25 feet in all vertical curves.
(4) 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.
(5) Elevations at all curb inlets.
(6) Extension of centerline profile 300 feet beyond property line or boundary on all streets that provide for access to adjoining property.
(7) 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.
(8) 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.
(9) All proposed water mains. storm sewers, and appurtenances.
(10) All crossings of existing utilities.
(11) Notes that may be necessary to explain the intent and purposes of the profile.
