2021 Oklahoma Statutes|Title 11. Cities and Towns|§11-36-213. Property chargeable with cost - Rules for apportioning costs.

|A. For the purpose of determining the area of assessment, a block shall be deemed to be the area bounded on all sides by streets and avenues, or municipal limits, irrespective of the designation thereof. The lots, pieces or parcels of land fronting or abutting upon any improvement shall be chargeable with the cost thereof to the center of the block where the abutting way is on the exterior of the block. |B. Each quarter block shall be charged with its due proportion of the cost of improving both the front and side streets on which the block abuts, together with the areas formed by street intersections and alley crossings, except such portions of street intersections and alley crossings as may be chargeable to railway companies. Each quarter block shall bear:1. Its due proportion of the cost of paving, curbing, and guttering the same;2. The cost of grading in proportion to the cost of grading the entire street being improved; and3. The proportionate cost for construction of catch basins, manholes, inlet and drainage pipes, sewers and utility connections in proportion to the cost of the entire area of the improvement drained.The board of appraisers shall determine the amount of benefits to each quarter block on account of the grading thereof and the installation and construction of necessary drainage therefor.C. When triangular or other irregularly shaped lots or tracts are to be assessed for an improvement, the cost of the improvement in excess of the benefits accruing to the lots shall be assessed against and borne by the municipality.D. If the improvement is made in an alley or other public way in the center of the block, the assessment shall be made upon the property abutting the alley to the exterior of the block. In case of an alley not in the center of the block, or if more than one alley is improved in the block, then the assessment shall be made against the property which fronts and abuts the alley according to the area specially benefited by the improvement as the board of appraisers shall determine and as confirmed by the governing body.E. If any of the property abutting upon an improvement shall not be a part of a block, or shall be a part of a block which is not square or rectangular in shape or shall be a part of a block which is not uniformly platted or subdivided, the governing body shall include such property in quarter block districts as nearly as practicable for the purpose of appraisement and assessment, and it shall determine the area of the property benefited by the improvement and the depth to which the property shall be assessed. In such cases the property shall be subject to assessment according to benefits as determined by the board of appraisers and as confirmed by the governing body and irrespective of whether or not the property immediately abuts upon the improvement. All such property within six hundred (600) feet of the improvement shall be deemed to be abutting thereon for the purposes of assessment.F. If a fractional part of a lot, parcel, or tract of land is within an assessment area, the benefit shall be computed for the fractional part; but the entire lot, parcel or tract of land under the same ownership of which the fractional part is a part shall be subject to assessment for such benefit.Laws 1977, c. 256, § 36-213, eff.
