   (E)   Residential district, manufactured home overlay; RM.
      (1)   The RM district, manufactured home overlay, is established as a high density overlay zone in which manufactured homes may be located in established manufactured home parks. This use is supplementary to the list of permitted uses in the base district. For this reason, this district is not listed in § 155.026.
      (2)   The purpose of the manufactured housing overlay district (RM) is to provide for the development of affordable housing in established residential zoning districts while maintaining the overall character of those districts. The intent of the prescribed conditions herein is to insure compatibility with existing housing stock. The manufactured home overlay shall be an overlay in the residential district areas as shown on the zoning map. The manufactured housing overlay district supplements the range of uses permitted in the underlying district. All other uses and regulations for the underlying district shall continue to remain in effect for properties classified under the overlay.
      (3)   The manufactured housing overlay district permits the use of class A manufactured housing in established manufactured home parks, in addition to the uses permitted by the underlying district. The following provisions regulating the construction, location and design of manufactured home parks are intended to further an orderly spatial development, secure an environment that insures adequate health and safety and welfare standards, and insure that adequate facilities for transportation, parking, water, sewerage and recreation are provided:

   (J)   Manufacturing and industrial district; I and I(SU). The industrial district is established for those areas of the community where the principal use of land is, or should be, industrial and warehousing. These uses, by their nature, may create some nuisance and are not compatible with residential, commercial and/or service establishments. These uses normally seek outlying locations on large tracts of land where the operations involved do not detract from the development potential of nearby undeveloped properties. It is not intended to permit in this district any use which is inherently obnoxious because of noise, odors, smoke, light, dust or dangerous materials. Permitted uses are contained in § 155.026.
   (K)   Floodplain district; FP. This district is established to protect developers and property owners from investing in improvements which may be subject to flooding or are located on lands which are otherwise unsuitable for urban development due to natural conditions.

         (c)   To a depth of 400 feet or the depth of one parcel, whichever is greater but not to exceed 400 total feet, in any industrial district abutting Salisbury Avenue.
      (2)   The commercial corridor overlay district shall be applied as an overlay to current general zoning districts, some of which may or may not be of a commercial, business or industrial area. The regulations contained in this district shall be supplemental to those contained in the underlying general zoning district. When conflicts between the two arise, the more restrictive regulations shall apply. Photographic examples of development (a) currently found in downtown Spencer, (b) preferred in the CC district both within and adjoining the downtown, and (c) not preferred anywhere in the district are shown below. Those pictures that depict development both preferred and not preferred are for illustrative purposes only and are designed to give the reader and property owners examples of how the development regulations contained in the CC district can be applied.
   (M)   Guidelines. The following guidelines shall apply to all uses:
      (1)   Any use permitted shall be fully compatible with all surrounding zoning districts.
      (2)   Any uses permitted shall be a type not appreciably damaged by floodwater.
      (3)   Any structure permitted shall be designed, constructed and placed on the land so as to offer the minimum obstruction to the flow of water.
      (4)   Any structure permitted shall be firmly anchored to prevent the structure from floating away and thus restricting bridge openings and narrow sections of the stream.
      (5)   Any structure permitted which is designed for human habitation shall not provide a threat to the safety of persons by virtue of potential floodwaters.
      (6)   Any permitted equipment, material or goods stored in the district shall be fully enclosed within a fence of a quality, strength, and anchoring and a height of at least six feet so as to prevent the equipment, material, or goods from floating downstream.
      (7)   When a use is listed as conditional in the floodplain district the Board of Adjustment shall require topographic data, engineering and other studies necessary to determine the effects of flooding on a proposed structure or use and/or the effects of the structure or use on the flow of water. The reports shall be completed by a licensed engineer, registered surveyor, hydrologist or other persons having sufficient technical knowledge.
      (8)   No structure, temporary or permanent, fill, including fill for roads and levees, obstruction, storage of materials or equipment or other use may be allowed which, acting alone or in combination with existing or future uses, reduces the capacity of the floodway or increases flood heights. Consideration of the effects of a proposed use shall be based on a reasonable assumption that there may be an equal degree of encroachment extending for a significant reach on both sides of the stream.
   (N)   Interstate business district; IB and IB(SU). The interstate business district is established to provide an area of commerce within the community for residents and interstate travelers alike. The business uses in this area depend on exposure to large flows of traffic associated with major thoroughfares.
