The performance bond shall include an amount to guarantee completion of all requirements contained in §§ 152.050 et seq. of these regulations, including, but not limited to, soil preservation, final grading, lot drainage, lawn-grass seeding, removal of debris and waste, fencing, and all other lot improvements required by the Commission. At the expiration of the performance bond, the county may enforce the provisions of the bond where compliance with the provisions of this section or any other applicable law, ordinance, or regulation has not occurred.
(A) Lot arrangement. The lot arrangement shall be such that there will be no foreseeable difficulties for reasons of topography or other conditions in securing building permits to build on each of the created lots in compliance with the Zoning Ordinance and health regulations and in providing driveway access to buildings on such lots from the appropriate approved street.
(1) Blocks shall have sufficient width to provide for two tiers of lots of appropriate depths. Exceptions to this prescribed block width shall be permitted in blocks adjacent to arterial streets, railroads, and waterways.
(2) The lengths, widths, and shapes of blocks shall be such as are appropriate for the locality and the type of development contemplated.
(a) Block lengths in residential areas shall not exceed 2,600 feet nor be less than 264 feet in length.
(b) Blocks along arterials and collector streets shall not be less than 1,000 feet in length or exceed 2,600 feet in length.
(3) In long blocks the Commission may require the reservation of easements through the block to accommodate utilities, drainage facilities, or pedestrian traffic. Pedestrian ways or crosswalks not less than ten feet wide, may be required by the Commission.
(a) Through the center of blocks more than 800 feet long or at other appropriate locations.
(b) At the end of culs-de-sac where deemed essential to provide for circulation or access to schools, playgrounds, shopping centers, transportation, or other community facilities.
(B) Lot dimensions.
(1) General. Lot dimensions shall comply with the minimum standards in the City of Marion Advisory Zoning Ordinance. Side lot lines shall be at right angles to the street lines (or radial to curing street lines) unless a variation from this rule will give a better street or lot plan. Dimensions of corner lots shall be large enough to allow for erection of buildings, observing the minimum front yard setback from both streets. Depth and width of properties reserved or laid out for business, commercial, or industrial purposes shall be adequate to provide for all of the off-street parking and loading facilities required for the type of use and development contemplated, as established in the Zoning Ordinance.
(2) Waterbodies and watercourses. If a tract being subdivided contains a water body, or portion thereof, lot lines shall be so drawn as to distribute the entire ownership of the water body among the fees of adjacent lots.
(a) The Commission may approve an alternative allocation of interests whereby the ownership and responsibility for safe maintenance of the water body is so placed that it will not become a local government responsibility.
(b) No part of the minimum area of a lot required under the Zoning Ordinance may be satisfied by land that is under water.
(c) Where a watercourse separates the buildable area of a lot from the street from which it has access, provisions shall be made for installation of a culvert or other structure of a design approved by the county or jurisdictional engineer.
(C) Double frontage lots and access to lots.
(1) Double frontage lots and reversed frontage lots. Double frontage lots and reversed frontage lots shall be avoided except where necessary to provide for the separation of residential development from the traffic on bordering arterials or to overcome specific disadvantages of topography and orientation affecting the subdivided lots.
(2) Access from primary and secondary arterials. Lots shall not, in general, derive access for a primary or secondary arterial street. Where driveway access from a primary or secondary arterial street may be the only possible access for several adjoining lots, the Commission may require that such lots be served by a combined access drive in order to limit possible traffic hazards from multiple access to such streets. Where possible, driveways should be designed and arranged so as to avoid requiring vehicles to back into traffic on primary or secondary arterials.
(3) Access to collector streets. Where possible, lots in single-family residential subdivisions fronting on collector streets shall be avoided. Lots at the corners of intersections between local and collector streets shall front on the local street and have driveway access to it only, not to the collector street. In multiple family residential areas entrances to group parking lots shall have access only to collector streets (where possible) and such entrances shall be widely spaced.
(4) Access to primary arterials. Where a subdivision borders on or contains an existing or proposed primary arterial, the Commission may require that access to it be limited by one of the following means:
(a) The lots back onto the primary arterial. The lots front onto a parallel local street. No access shall be provided from the primary arterial and screening shall be provided within a strip of land along the rear property line of such lots;
(b) A series of culs-de-sac, or loop streets entered from and designed generally to be at right angles to an access street that is at some distance from and parallel to the arterial street, with the rear lines of their terminal lots backing onto the arterial;
(c) A marginal access or service road should be separated from the primary arterial by a landscaped and/or decoratively fenced grass strip. The access road shall be at widely spaced suitable points.
(D) Soil preservation, grading, and seeding.
(1) Soil preservation and final grading. No certificates of occupancy shall be issued until final grading has been completed in accordance with the approved construction plans.
(a) The lot shall be pre-covered with top soil having an average depth of at least six inches which shall contain no particles over two inches in diameter over the entire area of the lot, except that portion covered by buildings or included in the streets.
(b) The grade shall have not been changed or natural vegetation seriously damaged. Topsoil that was removed from residential lots shall be redistributed so as to provide at least six inches of cover between the sidewalks and curbs and shall be stabilized by seeding or planting.
(2) Lot drainage. Lots shall be laid out so as to provide positive drainage away from all buildings and individual lot drainage shall be coordinated with the general storm water drainage pattern for the area, and drainage plans adopted by the Drainage Board or any participating jurisdiction. Drainage shall be designed so as to avoid the accumulation of storm water on any one or more lots from adjacent lots. It shall be the responsibility of the lot owner to maintain the lot grade, as it applies to drainage, as provided for in the approved construction plans.
(3) Lawn-grass seed and sod. No certificate of occupancy shall be issued until re-spreading of soil and seeding of lawn have been completed; except that between October 15 and March 15, the applicant shall submit an agreement in writing to the Administrator signed by the developer and the property owner that re-spreading of soil and seeding of the lawn will be done during the immediately following planting season.
(4) Debris and waste. No cut trees, timber, debris, earth, rocks, stones, soil, junk, rubbish, or other waste material of any kind shall be buried in any land or left or deposited on any area of the subdivision at the time of expiration of the performance bond or dedication of public improvements, whichever is sooner.
