The subdivider shall, at the subdivider's own expense, provide the following public improvements which shall meet the minimum design standards of this chapter and shall be shown on subdivider's final subdivision plan.
A. 
Type. Monuments shall be of concrete or stone with a minimum size of four inches by 36 inches long and shall be marked on top with a one-half-inch round brass pin or a drilled hole. Markers shall consist of iron pipes or iron or steel bars at least 24 inches long and not less than 1/2 inch in diameter.
B. 
Placement. Monuments and markers shall be placed so that the scored or marked point shall coincide exactly with the intersection of lines to be marked and shall be set so that the top of the monument or marker is level with the surface of the surrounding ground.
C. 
Location of monument. Monuments shall be set at the intersection of all lines forming angles in the boundary of the subdivision, at points where street right-of-way lines cross a boundary and at points of intersection of streets within the subdivision.
D. 
Location of markers. Markers shall be set:
(1) 
At the beginning and ending of all curves along street property lines;
(2) 
At all points where lot lines intersect curves;
(3) 
At all angles in property lines of lots; and
(4) 
At all other lot corners.
E. 
Replacement. Any monuments or markers that are removed shall be replaced by a registered engineer or surveyor at the developer's expense until such time as the developer's involvement in the subdivision ceases.
A. 
Minimum paving requirements. Streets shall be graded, surfaced, and improved to the grades and dimensions shown on plans, profiles, and cross sections submitted by the subdivider consistent with Borough specifications, approved by the Borough Council through resolution.
B. 
Other improvements. The Borough may require a heavier pavement and subbase than stipulated by the Borough street specifications if a proposed street will function as the main access to a large residential development or if the street will serve a commercial or industrial plan.
C. 
Subsurface drainage. Prior to laying down the street surface, adequate subsurface drainage and all subsurface utilities shall be provided or installed by the developer. The size of the storm drainage structures shall be computed by using Talbot's formula for runoff.
D. 
Slopes.
(1) 
Slopes of banks measured perpendicular to the center line of the street shall not exceed three to one for fills and two to one for cuts.
(2) 
In all aspects in which standards for required improvements are not set forth in this chapter or Borough specifications, the applicable standard requirements of the Pennsylvania Department of Transportation shall govern, and all work shall be performed in the manner prescribed in the standard specifications of that Department for the type of construction under consideration.
E. 
Approval, maintenance, and security. The work of constructing streets or roads, including the methods and materials incident thereto, shall be subject to the approval of the Borough, with advice of its engineer and professional consultants. Final acceptance of the completed streets or roads shall rest with the Borough Council. The developer shall enter into a contract with the Borough which provides that in consideration of the acceptance of the roads or streets for inclusion in the Borough street system, the developer agrees to construct the roads or streets in the subdivision or development to the standards prescribed herein at developer's own expense.
(1) 
In the event that the developer or subdivider desires to complete the construction of the streets after the plan is placed on record, the developer shall be required to submit a cost estimate prepared by a registered professional engineer setting forth all items of work to be performed and the estimated cost. The estimate shall be subject to the approval of the Borough Engineer. A certified check or contract performance bond issued by a surety company, subject to the approval of the Borough Council, in an amount equal to the approved estimate to insure the completion of the work, shall be filed with the Borough. All construction items shall be completed within one year after the plan is placed on record, except where bituminous paving construction is required. When bituminous construction is required, it shall be completed within two years after the plan is placed on record.
(2) 
The certified check shall be made payable to the Borough. In the event the work is satisfactorily completed within the time specified, the funds from the certified check, or surety bond as the case may be, shall be returned.
(3) 
The developer or subdivider shall be required to maintain all culverts, ditches, backslopes, and shoulders until the Borough accepts the street.
A. 
Every structure in any subdivision or development plan shall be connected to the public sewage disposal system.
B. 
Connection to the public system shall be in accordance with the ordinances, rules, and regulations of the Borough of Indiana.
C. 
No storm sewers, footer drains, or downspouts shall be connected to any sanitary sewage disposal system.
A. 
Every dwelling and each commercial or industrial business shall be connected to the public water supply.
B. 
Water lines shall be installed in accordance with the regulations of the company providing the water supply.
A. 
All areas of a subdivision or development plan to be developed shall be graded to assure positive drainage. Any areas that hold water, contain habitual swamp conditions, have no drainage outlet, or harbor insects or other disease-carrying or -producing agents shall be drained even though not otherwise to be developed, unless designed to create a permanent pond.
B. 
Storm sewers, culverts and related installations shall be provided to insure the unimpeded but controlled flow of natural watercourses and to guarantee the drainage of all low points along curblines or gutter lines, as well as at intervals related to slope, for all streets in or adjacent to the plan.
C. 
The intersection of driveways and streets shall be designed to permit uninterrupted flow along the gutter line or via a pipe of sufficient size to carry the runoff below the driveway. In no case shall stormwater flowing down a driveway be permitted to cross a public street on the surface.
D. 
Developers shall design their storm drainage system in accordance with the Indiana Borough Stormwater Management Ordinance[1] and/or applicable specifications.

The plan shall be prepared in accordance with requirements contained in the Soil Erosion and Sedimentation Control Manual published by the Pennsylvania DEP January 1974, as amended, and shall be acceptable, after review, to the Indiana County Office, Soil Conservation Service.
In any areas of the Borough where maps or data prepared by the U.S. Department of Housing and Urban Development, Flood Insurance Administration (Flood Hazard Area Maps), indicate a floodplain exists, development of any kind proposed to take place within such floodplain shall not be approved, and no building permits for construction shall be issued, unless requirements of the Borough Flood-Prone Area Regulations have been met.

E. 
Upon completion of all required public improvements in a subdivision plan or other development, plans and profiles of the improvements as completed shall be filed with the Borough.
