§ 152.059  LOTS.
   (A)   Area/width. The minimum lot area and width shall not be less than that established by the city zoning ordinance in effect at the time of adoption of the subdivision.
   (B)   Corner lots. Corner lots for residential use shall have additional width to permit appropriate building setback from both streets as required in the zoning ordinance.
   (C)   Side lot lines. Side lines of lots shall be approximately at right angles to street lines or radial to curved street lines.
   (D)   Building sites. Unless approved by the City Engineer upon the basis of plans submitted showing alternative acceptable surface drainage measures, each lot shall provide an adequate building finished floor elevation at least 12 inches above the top of the adjacent curb.
   (E)   Frontage. Every lot must have the minimum frontage on a city-approved right-of-way other than an alley, as required in the city zoning ordinance.
   (F)   Access. Each individual lot shall directly access a public street.
   (G)   Setback lines. Setback or building lines shall be shown on all lots intended for residential use and shall not be less than the setback required by the city zoning ordinance, as may be amended.
   (H)   Watercourses. Watercourses shall be contained within abutting lots. Watercourses shall be protected by easement to the anticipated high water level (as determined by the city). Lots with easements protecting watercourses shall have sufficient dimensions and area above the normal water mark.
   (I)   Drainage. Lots shall be graded so as to provide drainage away from building locations, subject to the approval of the City Engineer. A grading plan shall be submitted showing all lot grading and drainage provisions.
   (J)   Features. In the subdividing of any land, due regard shall be shown for all natural features, such as tree growth, watercourses, topography, historic spots, or similar conditions which, if preserved, will add attractiveness and stability to the proposed development.
   (K)   Lot remnants. All remnants of lots below minimum size left over after subdividing of a larger tract must be added to adjacent lots or outlot, rather than be allowed to remain as unusable parcels.
   (L)   Political boundaries. No subdivision shall extend over a political boundary or school district line without document notification to affected units of government.
   (M)   Frontage on two streets. Double frontage, or lots with frontage on two parallel streets, shall not be permitted except where lots back on major collector streets or county or state highways, or where topographic or other conditions render subdividing otherwise unreasonable. Such double frontage lots shall have an additional depth of at least 20 feet in order to allow space for screen plantings and/or buffering along the back lot line. As part of the subdivision review process, the submission of a buffering and screening plan may be required.
   (N)   Access to major collector streets.
      (1)   In the case where a proposed subdivision is adjacent to a major collector street, said streets to be defined by the city’s Comprehensive Plan, there shall be no direct vehicular access from individual lots to such streets and roads. In the subdividing of small tracts of land fronting on limited access highways or major collector streets where there is no other alternative, a temporary access may be granted, subject to terms and conditions defined by the City Council and applicable county or state agencies.
      (2)   As neighboring land becomes subdivided and more preferable access arrangements become possible, temporary access permits shall become void.
      (3)   In cases where direct lot access to collector or arterial streets is allowed, special traffic safety measures including, but not limited to, provisions for on-site vehicle turnaround shall be required.
      (4)   In cases where a proposed subdivision is adjacent to a county or state highway, the subdivision shall be subject to county and/or state approval.
   (O)   Outlots. Lot remnants and future subdivision development phases shall be platted as outlots. Typically, stormwater ponds shall be contained within outlots. In cases where outlots are created or exist, their area shall not be utilized in calculating minimums for buildable lot area requirements. Outlots are also prohibited from qualifying for building permits.
