1339.04  ELEVATION, FLOODPROOFING AND CONSTRUCTION STANDARDS.
   (a)   Residential Structures.  Within any Flood Plain District, the lowest floor, including basement, of all residential structures shall be constructed at or above the 100 year flood elevation.  Fully enclosed space below the lowest floor is prohibited.
(Ord. 3014.  Passed 11-20-95.)
 
   (b)   Nonresidential Structures.
      (1)   Within any floodplain district, the lowest floor, including basement, of all nonresidential structures shall be constructed at or above the 100 year flood elevation, or such structures shall be designed and constructed so that the space enclosed shall remain either completely or essentially dry during any flood up to that height.
(Ord. 2717.  Passed 2-10-86.)
      (2)   Any non-residential structure, or part thereof, having a lowest floor which is not elevated to at least one and one half feet above the 100 year flood elevation, shall be floodproofed in a completely or essentially dry manner in accordance with the W1 or W2 space classification standards contained in the U.S. Army Corps of Engineers publication entitled “Flood-proofing Regulations”, (amended 1992) or some other equivalent standard.
      (3)   Fully enclosed space below the lowest floor (including basement) is prohibited. 
(Ord. 3014.  Passed 11-20-95.)
 
   (c)   Drainage Facilities.  Adequate storm drainage shall be provided for development within any floodplain district.  Storm drainage facilities shall be designed to convey the flow of storm water runoff in a safe and efficient manner.  The system shall insure drainage at all points along streets, and provide positive drainage away from buildings.  The system shall also be designed to prevent the discharge of excess runoff onto adjacent properties.
(Ord. 2717.  Passed 2-10-86.)
 
   (d)   Sanitary Sewer Facilities.   No part of any on-site sanitary sewage disposal system shall be located within any identified flood plain area except in strict compliance with all State and local regulations.  Sanitary sewer facilities and systems shall be designed to minimize or eliminate the infiltration of flood waters into the systems and to prevent the discharge of untreated sewage into floodwaters, and be located and constructed to minimize flood damage.
(Ord. 3014.  Passed 11-20-95.)
 
   (e)   Water Facilities. All new or replacement water facilities shall be designed to minimize or eliminate infiltration of flood waters into the system, and be located and constructed to minimize flood damage.
 
   (f)   Utilities.  All utilities such as gas lines, electrical and telephone systems being placed in flood-prone areas shall be located and constructed to minimize the chance of impairment during a flood.
 
   (g)   Anchoring.  Within any floodplain district, all buildings and structures shall be firmly anchored in accordance with accepted engineering practices to prevent flotation, collapse or lateral movement. 
(Ord. 2717.  Passed 2-10-86.)
 
   (h)   Special Requirements for Manufactured Homes.
      (1)   Within any FW (Floodway District), manufactured homes shall be prohibited.
      (2)   Within any FA (General Floodplain District), manufactured homes shall be prohibited within the area measured fifty feet landward from the top-of- bank of any watercourse.
      (3)   Where permitted within any floodplain districts, all manufactured homes, and any additions thereto, shall be:
         A.   Placed on permanent foundation.
         B.   Elevated so that the lowest floor of the manufactured home is one and one half feet or more above the elevation of the 100 year flood.
         C.   Anchored to resist flotation, collapse, or lateral movement.
            (Ord. 2877.  Passed 12-17-90.)
 
   (i)   Materials.  All materials and utility equipment used shall be resistant to flood damage. 
(Ord. 2717.  Passed 2-10-86.)
 
   (j)   Within any identified floodplain district, fully enclosed spaces below the lowest floor of any new or substantially improved structure shall be prohibited.
(Ord. 2877.  Passed 12-17-90.)
 
   (k)   Streets.  The finished elevation of all new streets shall be no more than one foot below the Regulatory Flood Elevation.
 
   (l)   Storage. All materials that are buoyant, flammable, explosive or, in times of flooding, possibly injurious to human, animal, or plant life shall be stored at or above the Regulatory Flood Elevation.  In accordance with the Pennsylvania Flood Plain Management Act, any development which will be used for the production, storage or use of any of the following materials or substances shall be prohibited.
      (1)   Acetone
      (2)   Ammonia
      (3)   Benzene
      (4)   Calcium carbide
      (5)   Carbon disulfide
      (6)   Celluloid
      (7)   Chlorine
      (8)   Hydrochloric acid
      (9)   Hydrocyanic acid
      (10)   Magnesium
      (11)   Nitric acid and oxides of nitrogen
      (12)   Petroleum products
      (13)   Phosphorus
      (14)   Potassium
      (15)   Sodium
      (16)   Sulphur and sulphur
      (17)   Pesticides
      (18)   Radioactive substances, insofar as such substances are not otherwise regulated.
 
   (m)   Placement of Buildings and Structures. All buildings and structures shall be designed, located and constructed as to offer the minimum obstruction to the flow of water and have a minimum effect upon the flow and height of flood water.
 
   (n)   Electrical Components and Equipment.
      (1)   Electrical distribution panels shall be at least three feet above the 100 year flood elevation.
      (2)   Separate electrical circuits shall serve lower levels and shall be dropped from above.
      (3)   Electrical, mechanical, and utility equipment shall not be located below the Regulatory Flood Elevation.
 
   (o)   Fuel Supply Systems.  All gas and oil supply systems shall be designed to prevent the infiltration of flood waters into the system and discharges from the system into flood waters.  Additional provisions shall be made for the drainage of these systems in the event that flood water infiltration occurs.
