[Ord. 946, 1/14/1999, § 5.10]
1. 
The standards and requirements contained in Parts 5 and 6 are intended as the minimum for the promotion of the public health, safety and general welfare, and shall be applied as such by the Borough Planning Commission and Borough Council in reviewing all subdivision and land development plans.
2. 
Whenever other Borough regulations impose more restrictive standards and requirements than those contained herein, such other regulations shall prevail; otherwise, the standards and requirements of this chapter shall apply.
3. 
The layout or arrangement of the subdivision or land development shall conform to the comprehensive plan, any regulations or maps adopted in furtherance thereof, and any other official plans of the Borough which have been adopted.
4. 
The plan of the proposed subdivision or land development shall be coordinated with existing adjacent development in order to provide for harmonious development of the area as a whole.
5. 
Land shall be suited to the purpose for which it is to be subdivided or developed. Lands subject to hazards to life, health, or property such as may result from fire, flood, disease or other causes shall either be made safe for the purpose for which such land is proposed to be used, or such land shall be set aside for uses which shall not endanger life or property or further aggravate or increase the existing menace.
6. 
All subdivisions and land developments shall be reviewed to assure that all such proposals are consistent with the need to minimize flood damage, that all utilities and facilities, such as sewer, gas, electrical and water systems are located and constructed to minimize or eliminate flood damage, and that adequate drainage is provided so as to reduce exposure to flood hazards.
[Ord. 946, 1/14/1999, § 5.20]
1. 
General Standards.
A. 
All design elements of all streets, including horizontal and vertical alignment, sight distance, and super-elevation, are subject to review and approval by the Borough Council. When reviewing the design of streets, in addition to the standards in this chapter, the "Rural Design Criteria" in the Pennsylvania Department of Transportation, Design Manual, Part 2, Highway Design, January 1990 edition, and A Policy on Geometric Design of Highways and Streets, AASHTO, 1990 edition, shall be consulted to assure that the road design is in accordance with acceptable engineering practice.
B. 
For certain aspects of vertical and horizontal alignment discussed below, standards are determined by design speed of the road involved. For all proposed streets, the developer shall indicate the proposed design speed. The designated design speed is subject to the approval of the Borough Council. In general, the design speed on arterial streets shall be considered as 55 mph (to be determined in each individual case), on collector streets a minimum of 35 mph (to be determined in each individual case) and on minor streets 35 mph unless a lesser design speed is permitted by the Borough Council.
C. 
The speed limit proposed to be posted for streets shall not exceed the design speed.
D. 
Streets in and bordering a subdivision or land development shall be coordinated, and be of such widths and grades and in such locations as deemed necessary to accommodate prospective traffic, and facilitate fire protection.
E. 
The location and width of all proposed streets shall conform to the official plans which have been adopted by the Borough and shall be properly related to all existing streets, recorded streets, and official plans which have been adopted or approved by the Borough, county, or state.
F. 
Streets within the subdivision or land development and adjacent roads which will receive traffic from and distribute traffic to the subdivision or land development shall be adequate in construction, grade, width and capacity to accommodate traffic generated by the subdivision or land development.
G. 
The proposed street system shall extend existing or recorded streets at the same width as the existing or recorded streets if these streets meet or exceed the standards of § 22-502, Subsection 3. If the existing or recorded streets do not meet or exceed the standards of § 22-502, Subsection 3, the proposed street extensions shall meet the standards of § 22-502, Subsection 3.
H. 
Where, in the opinion of the Borough Council, it is desirable to provide for street access to adjoining property, streets shall be extended by dedication to the boundary of such property. The location and number of access points to adjoining properties are subject to Borough Council approval.
I. 
When streets will be extended to the boundaries of the subdivision or land development to provide for access to potentially developable tracts and sanitary sewer and/or water lines will be constructed in the streets within the developer's tract, the Borough Council may require extension of the sanitary sewer and/or water lines to the tract boundary in order to facilitate future extensions to abutting land.
J. 
If a subdivision proposes lots, all of which front on existing public roads, the Borough Council may require the developer to reserve land adequate to provide for future street access from the public roads on which the lots front to the land to the rear of the proposed lots. Such reserved areas shall be of such dimensions to permit the construction of streets meeting the standards of this chapter.
(1) 
When reservations for future streets will adjoin lots to be developed prior to the construction of the streets, the developer shall establish the proposed grades of the future streets and the extent of the area necessary for the construction of those streets. If the area necessary for the construction of the streets extends beyond the proposed street right-of-way lines, all excavation and grading necessary for the roads beyond the right-of-way lines shall be done as required improvements in conjunction with the subdivision which contains the adjoining lots or else construction easements shall be provided on the adjoining lots, sufficient to permit construction of the future street.
(2) 
Where reservations for future streets intersect existing streets, radii shall be provided for the reservations such that the requirements of § 22-502, Subsection 8F and G, of this chapter could be met for a street to be constructed in the future.
K. 
If lots or parcels in the subdivision are large enough for resubdivision, or if a portion of the developer's property is not proposed to be subdivided but could be subdivided in the future, the Borough Council may require the reservation of land adequate to provide for future street access to land which could be resubdivided or subdivided in the future and require that the location of land reserved for future streets be coordinated with the street system shown on the subdivision plan.
L. 
Connections shall be provided between streets within the subdivision or land development to provide adequate access for emergency vehicles, other vehicles, and pedestrians.
M. 
New minor streets shall be so designed as to discourage through traffic, but the developer shall provide for the extension and continuation of arterial and collector streets into and from adjoining properties when required by the Borough Council. Minor streets shall be extended and continued into and from adjoining properties when necessary for the proper development of and traffic circulation in the Borough.
N. 
Where a subdivision or land development abuts an existing street which does not meet the standards of this chapter, the Borough Council may require the dedication of land sufficient to widen the street to meet the standards of this chapter.
O. 
Where a subdivision or land development fronts on and will provide for vehicular access to and from an existing Borough road which does not meet the minimum cartway width requirements of this chapter, the Borough Council may require the developer to improve at his expense the Borough road cartway to meet those requirements. Pavement shall be constructed in accordance with the requirements of this chapter. In addition, provision shall be made for adequate drainage along the sides of the roads. Such drainage provisions shall be approved by the Borough Council.
P. 
Private streets (streets not to be offered for dedication) shall be designed and constructed in accordance with the requirements of this chapter and other Borough regulations.
Q. 
Where streets and other public improvements continue into adjoining municipalities, evidence of compatibility of design, particularly with regard to street widths, shall be submitted. The applicant shall coordinate such design with both municipalities to avoid abrupt changes in cartway width or in improvements provided.
R. 
The street system shall be designed with regard to:
(1) 
Consideration of existing topographical considerations.
(2) 
Providing buildable lots.
(3) 
Minimizing the number of street intersections, through encouraging the use of three-way rather than four-way intersections when intersections of minor streets are involved.
(4) 
Avoiding excessive lineal footage of street.
S. 
All drives within multiple-family and nonresidential developments which are intended for circulation within the development shall be designed to the horizontal and vertical alignment standards for streets contained within this chapter.
2. 
Partial and Half Streets. New half or partial streets will not be permitted, but wherever a tract to be subdivided borders an existing recorded half or partial street, the Borough Council may require the developer to provide adjacent to such half or partial street a reservation of land adequate to allow the construction of a road meeting the standards of this chapter.
3.

10. 
Cul-de-Sac Streets.
A. 
Dead-end streets are prohibited unless designed as cul-de-sac streets, provided that in the case of streets which are planned for future extension into adjoining tracts and will not be the primary means of access to any lot or dwelling unit, a turnaround is not required.
B. 
Except as provided in § 22-502, Subsection 10A, any street dead-ended for access to an adjoining property or because of authorized stage development shall be provided with a turnaround within the subdivision or land development and the use of such turnaround shall be guaranteed to the public until such time as the street is extended.
(1) 
If a cul-de-sac turnaround is offset, it shall not be offset to the right.
(2) 
Should a temporary cul-de-sac be proposed, arrangements satisfactory to the Borough Council and Borough Solicitor shall be made for construction and installation responsibilities of all improvements when the temporary cul-de-sac is abandoned and the street is extended.
(3) 
In the event that the Borough Council shall not consider development of adjoining property to be imminent, the Council may require that a permanent curbed cul-de-sac be constructed.
C. 
Cul-de-sac streets shall be at least 250 feet from the right-of-way line of the street intersected to the center of the turnaround. Cul-de-sac streets shall not exceed 1,000 feet in length as defined in this chapter and shall not furnish access to more than 20 dwelling units. The Borough Council may permit temporary culs-de-sac longer than 1,000 feet at its discretion if future extension of the cul-de-sac is likely in the opinion of the Council. At its discretion, the Council may permit culs-de-sac to serve more than 20 dwelling units when it believes adequate provision will be made for vehicular circulation and parking.
D. 
Unless future extension is clearly impractical or undesirable, the turnaround right-of-way shall be placed adjacent to the tract boundary with sufficient additional right-of-way width provided along the boundary line to permit extension of the street at full width.
E. 
All cul-de-sac streets, whether permanently or temporarily designed as such, shall be provided at the closed end with a fully paved turnaround. Minimum radius to the pavement edge or curb line shall be 50 feet, and minimum radius to the right-of-way line shall be 60 feet.

11. 
Street Names.
A. 
Proposed streets which are in alignment with others already existing and named shall bear the names of the existing streets.
B. 
In no case shall the name of a proposed street duplicate an existing street name in the Borough and the postal district, irrespective of the use of the suffix (street, road, avenue, boulevard, drive, way, place, court, lane, etc.)
C. 
All street names shall be subject to the approval of the Borough Council and postmaster having jurisdiction.
12. 
Service Streets (Alleys).
A. 
Service streets are prohibited in residential subdivisions except where required by the Borough Council to avoid direct driveway access to arterial or collector streets.
B. 
Service streets may be permitted by the Borough Council in other types of development, provided that the developer produces evidence satisfactory to the Council of the need for such service streets, and provided that the service streets are not the primary means of access.
C. 
Dead-end service streets are prohibited unless permitted at the discretion of the Borough Council. Dead-end service streets shall be terminated with a paved circular turnaround with a minimum radius, to the outer pavement edge (curb line) of 40 feet.
D. 
Parking is prohibited along service streets.
[Ord. 946, 1/14/1999, § 5.30]
1. 
Streets shall be designed to preclude or minimize the need for guide rail. The Borough Council may require guide rail to be placed for protection on embankments when a barrier is required in Design Manual, Part 2 Highway Design, by the Pennsylvania Department of Transportation, January 1990 edition.
2. 
Fixed obstructions along streets which would require guide rail shall be precluded or minimized. The Borough Council may require guide rail to be placed when a barrier is indicated as required for fixed objects in Design Manual, Part 2 Highway Design, by the Pennsylvania Department of Transportation, January 1990 edition.
3. 
The design and selection of guide rail shall be in accordance with the standards in Design Manual, Part 2 Highway Design, January 1990 edition, however, the Borough Council shall approve all guide rail systems.
[Ord. 946, 1/14/1999, § 5.40]
1. 
Layout. The length, width and shape of blocks shall be determined with due regard to the provision of adequate sites for buildings of the type proposed, zoning requirements, topography, and requirements for safe and convenient vehicular and pedestrian circulation, including the reduction of intersections with arterial and collector streets.
2. 
Length.
A. 
Blocks shall have a maximum length of 1,600 feet and a minimum length of 500 feet. The Borough may decrease the permitted maximum and/or minimum lengths of blocks if the topography of land, proposed lot sizes, or surface water drainage conditions warrant such a decrease.
B. 
Blocks along arterial streets shall not be less than 1,000 feet.
3. 
Depth. Residential blocks shall be of sufficient depth to accommodate two tiers of lots, except where reverse frontage lots are required or where prevented by the size, topographical conditions or other inherent conditions of the property.
4. 
Nonresidential Blocks. Blocks in nonresidential areas may vary from the elements of design detailed above if required by the nature of the use. In all cases, however, adequate provisions shall-be made for off-street parking and loading areas and pedestrian and vehicular circulation.
5. 
Crosswalks. Crosswalks may be required by the Borough Council whenever necessary to facilitate pedestrian circulation and to give access to community facilities. Such crosswalks shall have a minimum width of 10 feet and contain a walkway, constructed of a material approved by the Borough Council, with a minimum width of four feet.
[Ord. 946, 1/14/1999, § 5.50]
1. 
General Standards.
A. 
The size, shape and orientation of lots shall be appropriate for the type of development and use contemplated, and be in accordance with the provisions of the Borough Zoning Ordinance [Chapter 27]. Lots shall be capable of being built upon in accordance with the provisions of the Borough Zoning Ordinance [Chapter 27].
B. 
Side lot lines shall be at right angles to straight street lines and radial to curved street lines. Lot lines shall follow municipal boundaries rather than cross them.
C. 
The depth of residential lots shall not be less than one nor more than three times their width at the street line.
D. 
Depth and width of parcels intended for nonresidential uses shall be adequate for the use proposed and sufficient to provide satisfactory space for on-site parking, loading and unloading, setbacks, buffer yards and landscaping, etc.
E. 
Subdivisions shall be designed to avoid the creation of remnants of land. If remnants of land would result after subdividing, adequate provision, which shall be approved by the Borough, shall be made for the disposition and maintenance of those remnants.
F. 
Where an ultimate right-of-way line has been provided, all setbacks and lot areas shall be measured from such ultimate right-of-way line.
G. 
Wherever feasible, lots shall be designed so that buildings can be constructed above street grade. Where this is not possible, the developer shall indicate what measures are to be taken to assure proper drainage away from the buildings.
H. 
When only a portion of a tract is designed at a time and there exists the potential for development of the remainder of the tract, lots shall be designed such that they do not restrict access to the remainder of the tract, do not unduly restrict the potential development of the remainder of the tract, nor result in the creation of awkward or difficult-to-develop parcels in the remainder of the tract.
I. 
The maximum slope utilized when grading lots or streets along an adjoining tract of land not owned by the developer shall be a four to one slope ratio of horizontal distance to vertical distance.
2. 
Lot Frontage and Access.
A. 
All lots shall abut and have direct driveway access to an existing or proposed public street or private street meeting the requirements of this chapter.
B. 
Reverse frontage lots shall be avoided except where required by the Borough Council to restrict access to existing streets or to overcome specific disadvantages of topography or orientation. All residential reverse frontage lots shall contain a barrier to prevent vehicular access, subject to Borough Council approval, within the rear yard.
C. 
Where access to land within a subdivision or land development will be solely by proposed roads within an adjoining municipality, the Borough Council may require assurance from the adjoining municipality that adequate provisions have been made to insure construction of the proposed access roads.
D. 
When the rear wall of a building will face a public street, the Borough Council may require a landscape screen, fence, earth mounding, or similar screening device, subject to Borough Council approval, between the building and the public street.
E. 
After consideration of street speeds, traffic volumes, projected traffic generated at a proposed land use, and the location and arrangement of existing and proposed driveways and intersections, the Borough Council may require the developer to install at his expense an acceleration or deceleration lane, or both, to serve a proposed driveway or street. If additional street right-of-way is required to construct the acceleration or deceleration lane, the additional right-of-way shall be provided by the developer.
F. 
When required by the Borough Council, the developer shall furnish a study to the Borough which will provide the information necessary to permit the determination as to whether an acceleration or deceleration lane is required.
3. 
Lot Size. The minimum lot size and width requirements set forth in the Borough Zoning Ordinance [Chapter 27] shall be met.
4. 
Off-Street Parking.
A. 
Each proposed dwelling unit in a subdivision or land development shall be provided with a minimum of two off-street parking spaces.
(1) 
In the case of single-family or two-family dwellings and townhouses with on lot parking, such off-street parking spaces shall be provided behind the street right-of-way line and may be provided in an attached or separate garage, carport, or driveway. The spaces shall not be located within any clear sight triangle required by this chapter.
(2) 
In the case of multiple-family dwellings, such off-street parking spaces shall be provided in parking facilities located adjacent to, within or near the multiple family dwellings. Spaces shall not be located within a street right-of-way nor within any clear sight triangle required by this chapter. Each off-street parking space shall contain a minimum of nine feet by 18 feet. In addition, adequate aisles with a minimum width of 24 feet for maneuvering and movement of vehicles shall be provided. The grade of areas used for parking shall not exceed 6%. The grade of areas used only for access shall not exceed 10%.
B. 
Nonresidential development shall meet the off-street parking requirements of the Borough Zoning Ordinance [Chapter 27].
5. 
Driveways.
A. 
Subdivisions and land developments shall be provided with internal streets to which the lots will have driveway access in order to minimize the number of driveway intersections with existing public streets. This reduction in driveway intersections will minimize driveway intersections with existing Borough streets (thus lessening interruptions to traffic flow and accident hazards and minimizing sedimentation and runoff problems onto existing public streets).
B. 
All driveways which provide access to arterial and collector streets, if such driveways are permitted by the Borough Council, shall be designed with turnaround areas so that cars will not back onto the arterial and collector streets.
C. 
Provision shall be made at all intersections of driveways with streets to ensure adequate stormwater drainage and erosion and sediment control. The Borough Council may require subdivision and land development plans to show a typical treatment of the construction of driveways and handling of storm drainage where the driveways intersect a street. The Council may require as a condition to approval of a plan that prior to the issuance of zoning or building permits the specific proposals for the construction of a driveway and treatment of storm drainage and erosion and sediment control for that driveway be submitted to the Borough for approval.
D. 
Driveways shall be placed at locations at which sight distance is adequate to safely allow each permitted movement to be made into or out of the driveways; such that the free movement of normal street traffic is not impaired; such that the driveways will not create a hazard; and such that the driveways will not create an area of undue traffic congestion on streets. Applicable safe sight distance as established in the regulations of the Pennsylvania Department of Transportation shall be provided.
(1) 
The Borough Council may require the driveway to a lot which abuts two or more streets to be restricted to that street which can more safely accommodate its traffic. The Borough Council may also require a driveway to be located directly across from a street or driveway on the opposite side of the street the driveway intersects if the Council judges that offset driveways will create a safety hazard.
(2) 
The Borough Council may require the permissible location of a driveway for a lot to be shown on the subdivision or land development plan, and further require that driveway locations be subject to approval of the Council.
(3) 
A clear sight triangle shall be provided at the intersection of a driveway with a Borough Street.
(4) 
The clear sight triangle shall be established by connecting points a distance of 15 feet from the point of intersection of cartway or curb lines.
(5) 
Within such clear sight triangles, no vision obstructing object shall be permitted which obscures vision above the height of 30 inches, measured from the center line grades of the intersecting driveway and street.
E. 
The following standards shall apply to residential driveways:
(1) 
Driveway entrances or exits into a street from a corner lot on which a single family or two family dwelling is constructed shall be located at least 40 feet from the intersection of any street cartway lines.
(2) 
No driveway serving a dwelling shall be located within two feet of any side lot line, except in the case of driveways which adjoin one another or shared driveways.
(3) 
Minimum driveway width shall be 10 feet, the maximum driveway width shall be 20 feet, and radius of the driveway apron shall be no less than two feet and no more than 10 feet.
F. 
The following standards shall apply to nonresidential driveways:
(1) 
No use shall have more than two accessways to any one street for each 500 feet of frontage.
(2) 
The width, excluding radii, of entrances to and exits from parking areas, measured at the street line, shall conform to the following schedule:
Width in Feet
Minimum
Maximum
One Way
12
24
Two Way
24
36
(a) 
Each lane provided shall be a minimum of 12 feet in width.
(b) 
The radius of the edge of the driveway apron shall be at least 15 feet and no more than 35 feet, unless otherwise required by Borough ordinance.
(c) 
Provided, that along state legislative routes, if these standards are in conflict with Pennsylvania Department of Transportation requirements, driveways shall be designed to conform as closely as possible to the requirements of this chapter, while conforming to the requirements of the Pennsylvania Department of Transportation.
(3) 
Driveway entrances or exits into a street from a corner lot shall be located at least 60 feet from the intersection of any street cartway lines.

3. 
Standards for Drainage of Streets.
A. 
All streets shall be designed to provide for the discharge of surface water from their rights-of-way. The design storm shall be a ten-year frequency for residential subdivisions with a gross density less than six units per acre, and a twenty-five-year frequency for all other subdivisions or land developments.

Storm Event
Inches Rainfall
2-year
3.1
10-year
4.9
25-year
5.5
50-year
6.5
100-year
6.9
(2) 
The facilities shall be designed such that the peak discharge from the site after development does not exceed the peak pre-development discharge for the two-, ten-, and twenty-five-year storm events.
(3)

(c) 
The side slopes of the settled earth fill shall not be steeper than three horizontal to one vertical.
(d) 
A key trench at least two feet deep or extending down to stable subgrade, whichever is deeper, of compacted relatively impervious material (Unified Soil Classification CL or ML). Minimum bottom widths for the key trench shall be four feet. Maximum side slopes for the key trench shall be one horizontal to one vertical. A compacted impervious core at least eight feet wide at the top, having a maximum side slope of one horizontal to one vertical, shall extend for the full length of the embankment, and the top elevation shall be set at the twenty-five-year design water surface elevation.
(e) 
All pipes and culverts through dams shall have properly spaced concrete anti-seep collars (minimum six-inch thick). Design calculations shall be submitted for review.
(f) 
The top of berm shall be constructed at least six inches above the design elevations to allow for settlement of the embankment.
(g) 
The emergency spillway shall be constructed in undisturbed earth, or be of concrete construction along its bottom and sides.

When maximal provision is to be made for the use of solar energy by structures, in general streets toward which buildings are to be oriented should run in an east-west direction.
2. 
Section 22-505, Subsection 1B, indicates that side lot lines shall be at right angles to straight street lines and radial to curved street lines. The Borough Council may allow variation from this requirement where provision is to be made for maximal use of solar energy, in which case side lot lines generally may run from due north to due south or with slight variation east or west of this axis.
A. 
When lot lines will not be provided, consideration should be given to orienting buildings to maximize solar access. Generally, buildings should be located with their long axes running east to west, though in some high density or townhouse developments a north-south orientation for the long axes may be desirable.
B. 
Consideration should be given to locating structures and open spaces such that buildings will not cast shadows on other buildings.
3. 
Consideration should be given to reserving solar easements within lots for protection of solar access.
[Ord. 946, 1/14/1999, § 5.98]

Designation of Area.
A. 
Areas subject to this section shall include all areas of Duffield (DfA, DfB2, DfC2 and DfD2), Duffield and Hagerstown (DhC3 and DhE3), Fogelsville (FoA, FoB2 and FoC2), Hagerstown (HaB2 and HaC2), Murrill (MrA3, MuA, MuB2, MuC2, MvB and MvC), and Washington (WaA2, WaB2 and WaC2) soils.
B. 
In carbonate areas, alteration and development of land may be hazardous with respect to foundation safety of structures, the creation of unstable land as a result of changes in drainage, and the contamination of ground and surface waters. Within the limitations of the information available at the time of review of individual applications, the Borough shall attempt to make reasonable judgments as to the applicant's compliance with the standards of § 22-516, Subsection 2. Under no circumstances shall the Borough or any officer or employee of the Borough assume any liability for any damages that may result from an applicant's or any interested party's reliance upon the regulations of § 22-516, Subsection 2, or any decisions made by the Borough in the administration of such regulations.
2. 
Standards.
A. 
Land grading or construction of buildings or other site improvements shall not directly or indirectly diminish the flow of natural springs or contaminate existing or potential water supplies. If warranted, as determined by the Borough Council, water table data from observation wells shall be provided by the applicant.
B. 
All buildings, structures, roads and other impervious surfaces and storm drainage facilities and other utilities shall be so situated, designed and constructed as to minimize the risk of structural damage from existing or future sinkholes. A recognized professional with competence in the field shall demonstrate that a minimal risk of structural damage due to sinkholes will exist or indicate mitigating measures to be taken to minimize the risk of structural damage.
C. 
Whenever a detention or retention basin for the control of stormwater will be located in a carbonate area, a geological evaluation of the proposed location shall be conducted to determine susceptibility to sinkhole formation. The design of all facilities over limestone formations shall include measures to prevent ground water contamination and, where necessary, sinkhole formation. Soils used for the construction of basins shall have low-erodibility factors ("K" factors). The Borough may require the installation of an impermeable liner in basins. All detention facilities shall be above ground unless otherwise approved by the Borough Council.
D. 
The following guidelines shall be considered during construction activities.
(1) 
Care should be taken to prevent collection and drainage of surface water into excavated or low-lying areas of the site during excavation and construction.
(2) 
Soft and wet conditions should be located wherever they may exist or be encountered.
(3) 
Soft areas should be removed and replaced with suitable fill compacted in accordance with recognized standards, such as ASTM.
(4) 
The bottom of all excavations should be inspected for soft or unusually moist conditions. A visual inspection of the excavated bearing surface, together with soundings or probes of the soil at regular intervals, should be done.
(5) 
Any soft or unusually moist soil should be further excavated and a determination made of the extent of the problem. Remedial measures should be adopted as necessary.
(6) 
The low points of swales and outlet locations for drainage pipes should be lined with impermeable liners instead of stone rip-rap in order to prevent infiltration of runoff.
(7) 
Excavation should be kept to a practical minimum.
(8) 
Water from roof drains or other drainage systems should be collected and conveyed away from structures to prevent infiltration near foundations. If possible, roof drains should discharge directly into a storm sewer system or the street gutter.
(9) 
Subsoil erosion/sinkholes that occur during the construction of a project should be corrected as quickly as possible under the supervision of a qualified geotechnical engineer.
(10) 
Blasting should be avoided.
E. 
Should the Borough Council find that an applicant may create a significant risk to the public's health or safety, in spite of taking all reasonable actions to minimize such risks, or should the Council determine that the applicant has not taken all reasonable actions to minimize such risks, the Council may deny the application.
