  (2)   Jurisdiction: This Chapter shall apply to the subdividing of land within the corporate limits of the City of Menan. It may apply, as determined by the City Council and Jefferson County Commissioners, to the Impact Area as agreed to and adopted by the Jefferson County Commissioners.
  (3)   Special Conditions: Land where conditions are potentially harmful to safety or general health and welfare shall not be subdivided unless measures are taken to overcome the conditions (see chapter 10-5). Such conditions may include, but are not limited to, periodic flooding, poor drainage, or steep grades.
  (B)           General Requirements: The applicant shall be responsible for the following:
  (1)   Improvements such as streets, alleys, parks, easements, and other facilities requisite to plat approval.
  (2)   Providing plans prepared by an engineer.

  (6)   Improvements to be constructed and/or installed within two years of final plat approval, unless extended for one year by mutual consent.
  (7)   Guarantee of 110% of estimated cost as determined by the project engineer and including one or more of the following security arrangements, as approved by City Council:
  a.   Deposit with an escrow agent or trust company: a cash deposit, certified check, or irrevocable bank letter of credit.
  b.   Escrow time for periods specified for various improvements.
  c.   By mutual consent, an agreement for progressive reductions of the security amount upon completion of construction or installation stages.
  (8)   Maintenance agreement, for not less than one year and not more than five years, covering construction, installation, and operation of required improvements.

  i.    An escrow agreement shall be drawn and furnished to the city.
  ii.    A bond shall be with a surety company authorized to do business in Idaho
  iii.   A bond shall accrue to the city and shall cover construction or installation, operation, and maintenance of specified improvements.
  (C)          Lots and Blocks: Lots shall conform to the following:
  (1)   Except as provided below, the lot area provided shall conform to the district in which the subdivision is located.
  (2)   The lot depth and width shall be sufficient to meet the required setbacks of the district in which the subdivision is located.
  (3)   Corner lots shall have sufficient extra width to permit the required setback from both streets.
  (4)   Land with flood plains or other physical characteristics that severely hamper development may be subdivided if sufficient land remains in each lot outside the uninhabitable area to accommodate the required setbacks and a building envelope. As an alternative such land may be set aside as a park, trail, or open space.
  (5)   Where parcels of land are subdivided into large lots, the parcels shall be divided and developed to permit future subdivision into smaller parcels.
  (6)   In residential subdivisions with more than five lots, the sizes of the lots shall be averaged, and the average lot size shall be at least the minimum lot size required in the district in which the proposed subdivision is located. To illustrate, in a five-lot subdivision in the Traditional Residential District, three lots may be 0.3 acres, one lot may be 0.6 acres and the last lot shall be one acre. The purpose of this regulation is to avoid subdivisions in which all the lots are the minimum lot size permitted in the zone. In exchange for permitting some lots to be smaller than the minimum lot size, others must be considerably larger.

  (8)   Double frontage lots shall be avoided.
  (9)   Block length should not exceed 660 feet, measured from intersection center to intersection center.

The paving shall meet the minimum standards established in TITLE 8CHAPTER 5 of this title.
  (2)   Layout: Streets shall be laid out consistent with this code and the comprehensive plan with regard to existing streets, topographical features, public safety and convenience, and proposed land uses.
  (3)   Access to Arterials and Collectors: Individual lots in platted developments shall not have direct access onto an arterial or major collector, but onto a residential or local street or minor collector.

Unobstructed drainage easements shall be provided as required by the Council.
  (4)   Frontage Streets: Where a subdivision abuts or contains an existing or proposed arterial-street, railroad, or controlled access highway, the city may require frontage streets or other treatment appropriate to the situation.

In any case, a dead-end street serving more than four lots shall provide by easement a temporary turning circle with a 50' radius or other acceptable design. Where adjoining areas are not subdivided, streets in proposed subdivisions shall extend to the boundary line of the tract to permit future extension of said streets into adjacent areas. Spite strips are prohibited.
  d.   Loop Street: Loop streets shall have a maximum length of 1,200', measured along their centerline from center of intersection to center of intersection.
  (9)   Grades: Grades on collector, local, and residential streets shall not exceed 6% nor be less than 0.25%. Grade requirements for other streets shall be based on individual conditions and safe engineering practices.
