D. 
Identification of floodplain areas.
(1) 
Identification. The identified floodplain area shall be:
(a) 
Any areas of Borough of Malvern classified as special flood hazard areas (SFHAs) in the Flood Insurance Study (FIS) and the accompanying Flood Insurance Rate Maps (FIRMs) dated September 29, 2017, and issued by the Federal Emergency Management. Agency (FEMA) or the most recent revision thereof, including all digital data developed as part of the Flood Insurance Study.
(b) 
The above-referenced FIS and FIRMs, and any subsequent revisions and amendments, are hereby adopted by Borough of Malvern and declared to be a part of this section.
(2) 
Description and special requirements of identified floodplain areas. The identified floodplain area shall consist of the following specific areas:
(a) 
The Floodway Area shall be those areas identified in the FIS and the FIRM as floodway and which represent the channel of a watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without increasing the water surface elevation by more than one foot at any point. This term shall also include floodway areas which have been identified in other available studies or sources of information for those special flood hazard areas where no floodway has been identified in the FIS and FIRM.
[1] 
Within any floodway area, no encroachments, including fill, new construction, substantial improvements, or other development shall be permitted unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge.
[2] 
Within any floodway area, no new construction or development shall be allowed unless the appropriate permit is obtained from the Department of Environmental Protection Regional Office.
(b) 
The AE Area/District shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA for which base flood elevations have been provided.
[1] 
The AE Area adjacent to the floodway shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA for which base flood elevations have been provided and a floodway has been delineated.
[2] 
AE Area without floodway shall be those areas identified as an AE Zone on the FIRM included in the FIS prepared by FEMA for which base flood elevations have been provided but no floodway has been determined.
[a] 
No encroachments, including fill, new construction, substantial improvements, or other development, shall be permitted in an AE Zone without floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed development, together with all other existing and anticipated development, would not result in an increase in flood levels within the entire community during the occurrence of the base flood discharge.
[b] 
No new construction or development shall be located within the area measured 50 feet landward from the top-of-bank of any watercourse, unless the appropriate permit is obtained from the Department of Environmental Protection Regional Office.
(c) 
A Area/District.
[1] 
The A Area/District shall be those areas identified as an A Zone on the FIRM included in the FIS prepared by FEMA and for which no base flood elevations have been provided. For these areas, elevation and floodway information from other federal, state, or other acceptable sources shall be used when available. Where other acceptable information is not available, the base flood elevation shall be determined by using the elevation of a point on the boundary of the identified floodplain area which is nearest the construction site.
[2] 
In lieu of the above, the municipality may require the applicant to determine the elevation with hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough technical review by the municipality. In the absence of any of the above data or documentation, the community may require elevation of the lowest floor to be at least three feet above the highest adjacent grade.
(d) 
The AO and AH Area/District shall be those areas identified as Zones AO and AH on the FIRM and in the FIS. These areas are subject to inundation by one-percent-annual-chance shallow flooding where average depths are between one and three feet. In Zones AO and AH, drainage paths shall be established to guide floodwaters around and away from structures on slopes.
(3) 
Changes in identification of area. The identified floodplain area may be revised or modified by the Council where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change to the special flood hazard area, approval must be obtained from FEMA. Additionally, as soon as practicable, but not later than six months after the date such information becomes available, a community shall notify FEMA of the changes to the special flood hazard area by submitting technical or scientific data. See Subsection E(1)(b) for situations where FEMA notification is required.
(4) 
Boundary disputes. Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Borough of Malvern and any party aggrieved by this decision or determination may appeal to the Council. The burden of proof shall be on the appellant.
(5) 
Jurisdictional boundary changes. Prior to development occurring in areas where annexation or other corporate boundary changes are proposed or have occurred, the community shall review flood hazard data affecting the lands subject to boundary changes. The community shall adopt and enforce floodplain regulations in areas subject to annexation or corporate boundary changes which meet or exceed those in 44 CFR 60.3.
E. 
Technical provisions.
(1) 
General.
(a) 
Alteration or relocation of watercourse.
[1]

[2] 
No encroachment, alteration, or improvement of any kind shall be made to any watercourse unless it can be shown that the activity will not reduce or impede the flood-carrying capacity of the watercourse in any way.
[3] 
In addition, FEMA and the Pennsylvania Department of Community and Economic Development shall be notified prior to any alteration or relocation of any watercourse.
(b) 
When Borough of Malvern proposes to permit the following encroachments: any development that causes a rise in the base flood elevations within the floodway; or any development occurring in Zones A1-30 and Zone AE without a designated floodway which will cause a rise of more than one foot in the base flood elevation; or alteration or relocation of a stream (including but not limited to installing culverts and bridges), the applicant shall (as per 44 CFR 65.12):
[1] 
Apply to FEMA for conditional approval of such action prior to permitting the encroachments to occur.
[2] 
Upon receipt of the FEMA Administrator's conditional approval of map change and prior to approving the proposed encroachments, a community shall provide evidence to FEMA of the adoption of floodplain management ordinances incorporating the increased base flood elevations and/or revised floodway reflecting the post-project condition.
[3] 
Upon completion of the proposed encroachments, the applicant shall provide as-built certifications. FEMA will initiate a final map revision upon receipt of such certifications in accordance with 44 CFR Part 67.

If a driveway is to be located on a prohibitive steep slope, a driveway grading plan shall be submitted for approval to the Zoning Officer and Borough Engineer, subject to accepted engineering criteria consistent with the other applicable requirements of Borough ordinances. The grading plan shall be prepared by a licensed civil engineer and shall show:
[1] 
Existing and proposed contour grades at two-foot contour intervals within 25 feet of either side of the proposed driveway; and
[2] 
The centerline profile of the driveway showing slopes and vertical alignment of the proposed driveway.
(c) 
No more than 15% of such areas shall be altered or disturbed. The maximum impervious surface coverage of such areas shall be 5%. These standards shall apply on a per-lot basis.
(d) 
Any stockpiles of earth occurring during or after any land disturbance activity shall be seeded or otherwise stabilized when stored for more than 30 days.
(3) 
Uses. The uses permitted on prohibitive steep slopes shall be limited to the following:
(a) 
Open space reserved as part of a land development so long as no more than 25% of the open space has a slope greater than 25%.
(b) 
Wildlife sanctuary, woodland preserve, arboretum (exclusive of buildings or structures) and recreation areas (exclusive of buildings or structures).
(c) 
Tree farming, forestry and other agricultural uses (exclusive of buildings or structures) when conducted according to conservation measures approved by the Soil Conservation Service.
(4) 
Special exception uses on prohibitive steep slopes. The following uses shall be permitted as a special exception when authorized by the Zoning Hearing Board, subject to the requirements of this article. In addition to the criteria contained in Article XXVIII, the Board shall consider the extent to which the requested use will disrupt the stability of soils and natural vegetation and contribute to erosion before and after construction or installation of the permitted use. The Board shall attach such reasonable conditions as it determines necessary and reasonable in furthering the intent and purpose of this article.
(a) 
Sealed public water supply wells that have been approved by all regulatory agencies having jurisdiction.
(b) 
Sanitary or storm sewers that have been approved by all regulatory agencies having jurisdictions.
(c) 
Access roads suitable for passage of emergency vehicles in the event of fire or accident. Such roads shall be constructed only when no viable alternative for emergency access exists, providing all requirements of applicable codes and ordinances are met, and subject to approval by all regulatory authorities having jurisdiction.
F. 
Liability. Neither the approval, nor the granting of any building permit, subdivision or land development approval, or site development plan involving any land governed by the provisions of this article, by an officer, employee or agency of the Borough, shall constitute a representation, guarantee or warranty of any kind by the Borough, or its officers, officials, employees or agencies, of the practicality or safety of any structure, use or development, and the same shall create no liability upon or cause of action against the Borough, its officers, agencies, agents or employees for any damage that may result pursuant thereto. This chapter does not imply that areas outside defined steep slopes areas or land uses permitted within steep slope areas will always be totally free from the adverse effects of erosion or the effects of nearby steep slopes.
All uses and activities established after the effective date of this chapter shall comply with the following standards.
A. 
Applicability.
(1) 
Site alterations, regrading, filling or clearing of vegetation prior to the submission of applications for zoning or building permits or the submission of plans for subdivision or land development shall be a violation of this chapter.
(2) 
Wetland areas shall not be altered, regraded, developed, filled, piped, diverted or built upon, except where state and federal permits have been obtained.
B. 
Identification. An applicant shall identify and delineate wetlands on a site prior to the issuance of any building permit or subdivision and land development approval in accordance with this section and § 220-2205. Wetlands boundaries shall be delineated through a full wetlands report conducted by a qualified scientist and such report shall certify that the methods used correctly reflect current accepted technical approaches. Such a professional shall certify that the methods used correctly reflect the currently accepted technical concepts, including identification and analysis of wetland vegetation, hydric soils, and hydrologic indicators. The wetland report shall include a determination of whether wetlands are present on the site and a full delineation, area measurement (in square feet), and description of any wetlands determined to be present. In the event that a wetlands delineation validated by the United States Army Corps of Engineers is shown to vary from the wetlands boundary derived from the wetlands report, the Corps delineation shall govern.
C. 
Federal and state regulations. For proposed uses, activities or improvements which would entail the regrading or replacement of fill in wetlands, the applicant shall provide the Borough with proof that the Pennsylvania Department of Environmental Protection (Bureau of Dams and Waterway Safety) and the United States Army Corps of Engineers have been contacted to determine the applicability of state and federal wetland regulations for areas identified as wetlands on National Wetland Inventory (NWI) maps, United States Fish and Wildlife Service, or which meet these agencies' definitions of wetlands.
D. 
No more than 20% of a wetland margin area shall be altered, regraded, filled or built upon. Additionally, any Department of Environmental Protection regulations concerning activities related to wetland margins shall be met.
[Amended 3-21-2006 by Ord. No. 2006-5]
The intent of this section is to promote conservation of woodland resources in the Borough through resource identification, planning and development limitations. An applicant shall identify and delineate woodlands on a site prior to the issuance of any building permit or subdivision and land development approval in accordance with this section and § 220-2205.
A. 
Standards for land disturbance.
(1) 
Unless undertaken as an approved tree harvesting activity conducted in compliance with the requirements, as follows, no more than 60% of woodlands shall be regraded, cleared, built upon or otherwise altered. Where woodlands overlap other protected natural resources, the more restrictive disturbance standard shall apply.
(2) 
Replacement plantings shall be required as provided in § 181-525D of the Malvern Borough Subdivision and Land Development chapter where any land disturbance exceeds the standards set forth therein.
(3) 
Preserved woodlands may be used to provide vegetative buffers required by Article XXIII of this chapter.
(4) 
A tree harvesting plan may be required by the Borough, and shall include a description through text and maps of proposed actions involving the removal of trees from a tract of land. Such plan shall have been prepared by a licensed forester with demonstrable expertise in forest management, and shall document measures to be taken to protect water quality; minimize impacts from skid trails and logging roads, land areas, and the tree removal process; and ensure site restoration.
B. 
Guidelines for determining permitted woodland disturbance. In determining where permitted woodland disturbance will occur, the following factors shall be considered:
(1) 
Each building or structure shall be constructed in such a manner as to provide the least alteration necessary of the existing woodland. Where possible, clear-cutting shall be minimized and trees shall be selectively removed.
(2) 
Where possible, the remaining undisturbed woodlands and other vegetation shall interconnect with woodlands or wooded areas of adjacent properties to preserve continuous woodland corridors and allow for the normal movement, dispersion, and migration of wildlife.
(3) 
Woodland alterations that would threaten the growth of remaining trees shall be avoided.
C. 
Protection of specimen vegetation.
(1) 
No specimen vegetation shall be removed from any lot or tract except where applicant demonstrates to the satisfaction of the Borough that such removal is essential to eliminate hazardous condition(s). In consideration of any need for tree removal, the Borough may engage the services of an arborist, reasonable costs therefor to be borne by the applicant.
(2) 
To the minimum extent necessary to permit retention of specimen vegetation while providing for lawful use, modification to otherwise applicable area and bulk requirements may be approved in the following situations:
(a) 
Where approved by the Borough Council as part of any applicable subdivision or land development application; or
(b) 
Where approved by the Zoning Officer upon approval of any applicable building permit; and
(c) 
Provided that no applicable yard area setback shall be reduced more than 50%, except where approved as a variance by the Zoning Hearing Board.
(3) 
Where any applicant for building, zoning, subdivision or land development approval establishes conservation restrictions acceptable to the Borough which shall result in the conservation of specimen vegetation, all such specimen vegetation to be retained shall be credited toward any tree replacement required as provided in the Malvern Borough Subdivision and Land Development Ordinance,[1] at the ratio of four trees credited for each tree or plant to be retained which has been identified as specimen vegetation.
