The construction of improvements shall be in accordance with the requirements of this section. It is the intent of these regulations that these construction requirements shall be for the purpose of establishing a standard of quality and durability.
Survey monuments and markers shall be placed at all points as determined by the following criteria:
A. 
Monuments shall be concrete with a three-eighths-inch metal dowel in the center at the top. Monument size shall be no less than four inches by four inches by 30 inches. Where double monuments are used, the top monument shall be as described in the preceding sentence, the bottom monument shall be concrete with a three-eighths-inch metal dowel in the center at the top. A bottom monument shall be no less than six inches by six inches by six inches in size.
B. 
Markers shall be ferrous rods, five-eighths-inch minimum diameter by 18 inches minimum length, or may be standard manufactured steel survey markers of a similar length.
C. 
Monuments shall be placed so that the center point shall coincide exactly with the intersection of lines to be marked.
D. 
Monuments shall be placed so that they protrude approximately two inches above grade in areas which are not paved, at grade if in a paved area not subject to vehicle traffic, and four inches to eight inches below grade if in a paved area subject to vehicle traffic. Monuments set in areas subject to traffic shall be protected with a cast iron frame and access cover of adequate design for truck traffic, or may have double monuments, one above the other, with the top monument flush with the pavement.
E. 
Markers shall be driven into the ground so as to be approximately flush with the final grade.
F. 
Monuments shall be set at the intersection of all lines forming angles in the boundaries of major subdivisions and at all street angle points, and at the intersection of all street center lines.
G. 
Markers shall be set at all lot angles and corners, and at the beginning and end of all curves in lot and street lines. Curves for corner radii at intersection need not be marked if the intersection is monumented.
A. 
The applicant shall contact the Municipal Authority for the specifications of a water supply system. Prior to the approval of the preliminary plan, the applicant shall provide documentation to the Borough and Borough Planning Commission that arrangements for the provision of the water system are proceeding satisfactorily.
B. 
Fire hydrants shall be provided concurrently with the water supply.
C. 
If a development requires such additional water supply as to require changes to the local municipality's water distribution system, the applicant will be requested to pay a share of the costs consistent with the provisions of Act 203 of 1990. It is the purpose of these regulations that developments which occur under this chapter shall pay their fair share toward needed improvements as set forth by Act 203 of 1990.
D. 
When a municipal or community water supply system is reasonably available (within 500 feet), each lot in the subdivision or land development application shall be capable of being provided with an individual water supply system in accordance with the minimum standards approved by the Pennsylvania Department of Environmental Protection standards.
A. 
Where required, the developer shall construct a sanitary sewer system and provide lateral connections for each lot in accordance with the specifications of the Borough.
B. 
The developer shall secure from the Borough, prior to approval of the preliminary plan, a letter indicating the general design, location and preliminary approval of the proposed sanitary sewer collection system. Prior to the approval of the final plan, the developer shall supply documentation attesting to the installation of the sanitary sewer collection system and its approval/acceptance by the Borough. The developer may also offer an acceptable financial surety in lieu of this arrangement.
C. 
If a development generates such additional sanitary sewer flows as to require changes to the Borough's sanitary sewer collection system, the developer will be requested to pay a share of the costs consistent with the provisions of Act 203 of 1990. It is the purpose of these regulations that developments which occur under this chapter shall pay their fair share toward needed improvements as set forth by Act 203 of 1990.
D. 
On-lot sewage disposal. In subdivisions where public sewers are not available and a complete private sanitary sewer system is not required, on-lot sewage disposal systems shall be provided. In such instances, the developer shall provide evidence that the planning module required for on-lot disposal by DEP has been approved. The developer must show compliance with Act 537, and other state, county or local law and/or regulation governing on-lot sewage disposal.
A. 
A stormwater drainage system adequate to serve the needs of the proposed natural waterways and overland flow will be required in new subdivisions. The applicant shall construct a stormwater drainage system and connect the system with the existing local municipal storm sewer system if one exists.
B. 
If a development generates such additional stormwater flows as to require changes to the Borough's stormwater collection system, the applicant will be requested to pay a share of the costs consistent with the provisions of Act 203 of 1990. It is the purpose of these regulations that developments which occur under this chapter shall pay their fair share toward needed improvements as set forth by Act 203 of 1990.
C. 
Bridges or culverts shall be designed to support and carry loads according to the requirements of the Borough Engineer, but not less than AASHTO Loading HS-20 and shall be constructed the full width of the cartway plus additional length as necessary to provide a proper installation.
D. 
Where open watercourses are planned, adequate safety, erosion control, drainage, protection of capacity and appearance measures shall be taken by the developer to insure proper, safe, healthful disposal of stormwater. All open watercourses must be approved by the Borough Engineer.
E. 
Minimum grade of drainage courses shall be designed to create a minimum cleaning effect (velocity of two feet per second). Lesser grades may be permitted by the Borough Engineer where such required grades cannot be achieved.
F. 
Storm sewers shall have a minimum diameter of 15 inches and a minimum grade of 1/2 of 1%. Lesser grades may be permitted when substantiated with calculations which prove that cleaning velocities will be maintained.
G. 
Manholes shall normally be spaced at 300 feet maximum spacing where pipe sizes of 24 inches or less are used, and not over 400 feet where larger sizes are installed. Inlets may, if approved by the Borough Engineer, be substituted for manholes.
H. 
All phases of construction of open ditches, gutters or storm sewers including width, depth, shapes, erosion control, minimum grade, size and area shall be in accordance with the requirements of these regulations and all storm drainage facilities shall be inspected and certified by the Borough Engineer.
I. 
See also the Borough's Stormwater Management Regulations, Chapter 203 of the Borough's Code of Ordinances.
A. 
Streets shall be graded to the full width of the right-of-way, surfaced, curbed and improved to the grades and dimensions shown on plans, with profiles and typical cross sections submitted by the developer and approved by the Borough Engineer.
B. 
Side slopes shall be graded to blend with the natural lay of the land, or in accordance with cross sections approved by the Borough Engineer. Where fill material is necessary to establish uniform grades, compacting shall be required in accordance with Pennsylvania Department of Transportation Form 408 Specifications for embankment. A slope of two horizontal feet to one vertical foot beyond the right-of-way line in cut or fill shall ordinarily be required.
C. 
The subgrade shall be shaped to rough lines and elevations equal to the width of the pavement plus two feet. Adequate drainage facilities shall be installed to provide for the disposition of underground seepage and the percolation of surface water. The subgrade shall be thoroughly compacted by power rollers as required by the Borough Engineer. It shall be compacted at optimum moisture content. The finish surface shall be uniformly shaped to facilitate drainage, and any irregularities from planned grade shall be corrected prior to placing the subbase. Where material encountered in the normal excavation has a C.B.R. value of 2.5 or less and will not develop the required stability and provide for adequate drainage, the area shall be undercut and granular material added to a depth of at least 12 inches. It shall then be brought to a firm and thoroughly compacted surface as hereinbefore specified. The prepared subgrade shall be protected by the contractor to prevent undue rutting from trucks or other equipment and if such damage does occur, the subgrade shall be reshaped and compacted prior to placing the subbase material.
D. 
Subdrains shall be designed and installed per the specifications of the Borough Engineer.
E. 
All pavement, base, subbase (where required) and sidewalks shall conform to the requirements of the Borough Engineer.
F. 
Areas between the sidewalk and curb (if required) shall be seeded as required by the Borough Engineer.
G. 
See § 221-30 for curb and sidewalk specifications.
Gas, electric and telephone utilities shall be located in subdivisions in accordance with utility company practice and in accordance with agreements with, or as approved by, the Borough Engineer.
Street trees of a deciduous hardwood type with a minimum caliper of 1 1/2 inches shall, when provided, be planted between the curb and the sidewalk (if required), provided that the planting strip is a minimum of six feet wide and located as near the center of the planting strip as possible, but at no instance shall a tree be planted closer than three feet to the curb, sidewalk or any other utility above or below the ground. The tree species shall be subject to the approval of the Borough.
Streetlighting shall be provided if required by the Borough in accordance with their practice.
In wooded areas, floodplains, wetlands, areas having slopes of 15% or greater or where other natural conditions exist in such a manner that development would be hazardous to the safety of life and property or would cause permanent ecologic instability, the Borough may require that the applicant preserve as much of the original natural conditions as is economically feasible and ecologically practicable and may limit the amount of grading and excavating to the minimum improvement standards included herein.
It shall be a requirement of all subdivisions that the applicant provide a soil erosion and sedimentation control plan and/or permit, prepared in accordance with current state law (Erosion and Sedimentation Control, Chapter 102, Pennsylvania Rules and Regulations, as amended), reviewed by the Lawrence Conservation District. The plan shall be fully implemented during the construction of the development.
