§ 155.176  DESIGN STANDARDS AND SPECIFICATIONS.
   (A)   Monuments.
      (1)   General. All monuments shall properly set flush with the ground and be approved by a registered land surveyor or engineer prior to the time the Plan Commission recommends approval of the final plat.
      (2)   External boundaries.
         (a)   The external boundaries of a subdivision shall be monumented in the field by monuments of stone or concrete, not less than 30 inches in length, not less than 4 inches square or 5 inches in diameter, and marked on top with a cross, brass plug, iron rod or other durable material securely embedded.
         (b)   The spacing and exact location requirements shall be established by the Building Commissioner. The Plan Commission may amend these requirements.
      (3)   Internal boundaries. All internal boundaries and those corners and points not covered by the preceding division (2) shall be monumented in the field by steel or iron rods 1/2 inch in diameter or iron pipe 1 inch in diameter and at least 24 inches long. These monuments shall be placed at all block and lot corners, at each end of all curves (P.C. and P.T.), and at all internal angle points as required by the Building Commissioner.
   (B)   Traffic-control devices.
      (1)   Street name and regulatory signs. The applicant shall install street name signs in accordance with the Town of Beverly Shores design standards and the Manual on Uniform Traffic Control Devices of Indiana. One sign shall be installed at each intersection indicating the name of each street thereat. Other regulatory signs shall be the responsibility of the Town of Beverly Shores.
      (2)   Warning signs and other devices. Local government shall be responsible for the installation of all warning signs and other traffic control devices, except when warranted in commercial areas, the developer may be required to pay the cost.
   (C)   Streets and roads.
      (1)   General. In order to provide for streets of suitable location, width and improvement to accommodate expected traffic and afford satisfactory access to police, fire fighting, snow removal, sanitation and road maintenance equipment, and to coordinate street development so as to compose a convenient system, avoid undue hardships to adjoining properties and assure compatibility with long range comprehensive plans, all streets shall be designed according to the geometric standards set forth in these regulations.
      (2)   Principles of design. Subdivision street design shall follow regulations for this purpose adopted by the Town Council of Beverly Shores.
   (D)   Drainage facilities.
      (1)   General. The Plan Commission shall not recommend for approval any plat of a subdivision which does not make adequate provision for a storm or flood water runoff. The drainage system shall be separate and independent of any sanitary sewerage system. Inlets shall be provided so that surface water is not carried across or around any intersection, nor for a distance of more than 400 feet in any gutter. Surface water drainage patterns shall be shown for each lot and block.
      (2)   Requirements for storm sewers. The applicant may be required by the Plan Commission to carry away by pipe or open ditch, any spring or surface water that may exist either previously to, or as a result of, the subdivision. These drainage facilities shall be located in the road right-of-way where feasible, or in perpetual unobstructed easements of appropriate width. Drain facilities shall be provided under driveways so that the flow of water in ditches is not impeded.
      (3)   Flood plain areas. The Plan Commission shall, when it deems necessary for the health, safety or welfare of the present and future population of the area and necessary to the conservation of water, drainage and sanitary facilities, prohibit the subdivision of any portion of the property which lies within the floodplain. Any approvals within the floodplain shall, at a minimum, meet the requirements of the Indiana Department of Natural Resources.
      (4)   Drainage easement. Where a subdivision is traversed by a watercourse, drainage way, channel or stream, the subdivider shall provide a storm water easement or drainage right-of-way conforming substantially to the lines of the watercourse, and of a width and construction as will be acceptable to the Building Commissioner. The easement shall be adequately monumented, and whenever possible it is desirable that the drainage be maintained by open channel with landscaped banks.
   (E)   Water facilities.
      (1)   General.
         (a)   Necessary action shall be taken by the applicant to extend or create a water supply system capable of providing water for domestic use and fire protection.
         (b)   The location of all water supply improvements, shall be shown on the preliminary plat, and the cost of providing and installing same shall be included in the performance bond.
      (2)   Individual wells and central water systems.
         (a)   In low-density zoning districts and in outlying or rural areas where a public water system is not available, in the discretion of the Plan Commission, individual wells may be used or a central water system provided in a manner so that an adequate supply of potable water will be available to every lot in the subdivision.
         (b)   Individual wells and central water systems shall be sampled and approved by the appropriate health authorities.
   (F)   Sewage facilities.
      (1)   General. The applicant shall install sanitary sewer facilities in a manner prescribed by the Porter County Board of Health and subject to the specifications, rules, regulations and guidelines of the Porter County Board of Health.
      (2)   High-density Residential and Nonresidential Districts. Sanitary sewer facilities shall connect with public sanitary sewer systems. Sewers shall be installed to serve each lot and to grades and sizes required by appropriate local officials and agencies. No individual disposal system or treatment plants (private or group disposal systems) shall be permitted.
      (3)   Low and medium-density Residential Districts. Sanitary sewer systems shall be constructed as follows.
         (a)   Where a public sanitary sewer system is reasonably accessible (as determined by the Plan Commission) the applicant shall connect with same and provide sewers to each lot in the subdivision.
         (b)   Where public sanitary sewer systems are not reasonably accessible but will become available within a reasonable time not to exceed 15 years the applicant may choose to install 1 of the following alternatives:
            1.   Central sewage system with the maintenance cost to be assessed against each property benefitted. Where plans for future public sanitary sewer systems exist, the applicant shall install the sewer lines, laterals, mains in conformance with plans and ready for connection to future sewer mains; or
            2.   Individual sewage disposal systems, provided the applicant shall install sanitary sewer lines, laterals and mains to a point in the subdivision boundary where a future connection with the public sewer main shall be made. Sewer lines shall be laid from the individual dwellings to the street line and a connection shall be available in each dwelling to connect from the individual disposal system to the sewer system when the public sewers become available. These sewer systems shall be appropriately capped until ready for use.
         (c)   Where sanitary sewer systems are not reasonably accessible and will not become available within an estimated 15-year period, the applicant may install sewage systems as follows.
            1.   Medium-density Residential Districts shall have a central sewage system. No individual disposal system will be permitted. The Commission may however, where plans exist for a public sewer system to be built beyond a period of 15 years, require that the applicant install all sewer lines, laterals and mains in conformance with the plans and ready for connection to the public sewer mains.
            2.   Low-density Residential Districts may have individual sewage disposal systems or a central sewage system can be used.
      (4)   Mandatory connections to public sewers. If a public sanitary sewer is accessible and a sanitary sewer is placed in a street or alley abutting upon a property, the owner thereof shall be required to connect to the sewer for the purpose of disposing of waste. It shall be unlawful for any owner or occupant to maintain upon the property an individual sewage disposal system.
      (5)   Individual disposal system requirements. Minimum lot areas shall conform to the requirements of the Zoning Ordinance and individual septic systems shall conform to the requirements of the Porter County Health Department requirements.
