§ 5. Platting requirements.

1.

Blocks:

a.

Blocks shall be laid out with special attention given to the type of use contemplated.

b.

Residential blocks shall be wide enough to provide two tiers of lots of minimum depth, except where fronting on freeways, expressways or major thoroughfares, or prevented by topographical conditions or size of the property. In such case the commission may approve a subdivision containing a single tier of lots of minimum depth.

c.

Length of blocks shall be from 400 to 1,200 feet. Residential blocks shall not be less than 400 feet or more than 1,200 feet in length, except as the commission considers necessary to secure efficient use of land or to achieve desired features of the street system. In blocks over 800 feet long, the commission may require public crosswalks across the block.

d.

The width of blocks shall be from 250 to 400 feet.

2.

Lots:

a.

Lot sizes, shapes and locations shall be made with due regard to topographic conditions, contemplated use, and the surrounding area. A resubdivision, or a subdivision in an area already subdivided, shall improve rather than detract from the surrounding neighborhood.

b.

Size, shape and arrangement of commercial and industrial lots, where platted, shall be subject to the approval of the commission, provided that approval is not granted under the provisions of article V, section 5 of these rules and regulations.

c.

Every lot must abut upon a dedicated public street.

d.

Lots, other than corner lots, fronting on two streets shall not be permitted.

e.

Side lot lines shall be substantially at right angles to streets, except on curves where they shall be radial. Where the distance between rear lot corners on double tiered lots would be less than ten feet, the lot lines shall be deviated so that the property corners along the rear lot line will coincide.

f.

The area of all lots must conform to the requirements of the zoning ordinance. In all cases where there is no reasonable possibility of sanitary sewer service, the individual lots must be of sufficient size to accommodate a suitable sewage disposal device which shall conform to health department regulations. In such cases minimum lot sizes shall be determined as follows: A subdivider shall conduct a percolation test on each proposed lot in a subdivision and indicate the location and result of each test held on the preliminary plat. The dimensions and area of each lot will then be established at levels necessary to fulfill state health department regulations for disposal [of] septic tank effluent.

g.

All building and setback lines shall conform to requirements established in the zoning ordinance.

h.

Where easements for public utilities or storm or sanitary sewers are contemplated, the lot lines shall be platted so as to facilitate the construction and maintenance of said improvements.

3.

Parking facilities and loading docks:

a.

In residential areas, off-street parking facilities shall be provided as specified by the zoning ordinance.

b.

In other than residential districts, adequate space for off-street parking facilities and loading docks shall be provided as required by the zoning ordinance, and approved by the commission.

4.

Public areas: In all large subdivisions it is recommended that a suitable amount of open spaces be provided and dedicated for public use unless there are such facilities already available and of adequate size in close proximity to comply with acceptable city or state standards. Dedication of all such areas shall be subject to approval and acceptance of the tract(s) proposed for dedication by the park and recreation commission and the board of aldermen.
