of the FEMA floodway lines and/or the location of the FEMA flood fringe line. LOT A parcel of land having frontage on a public street or other officially approved means of access. LOT FRONTAGE The lot width measured at the street right-of-way line from which the lot obtains access.
LOW IMPACT DEVELOPMENT (LID) A method of site development and stormwater management that mimics the natural hydrologic functions of infiltration, runoff, and evapotranspiration on a site before development occurs. The objective of Low Impact Development is the volume of runoff leaving the site after development matches the volume of runoff before development. In addition, a LID project should maintain adequate flows to the streams and wetlands on the site rather than piping stormwater to a single low point. LOW IMPERVIOUS SURFACE PROJECT A project that has no more than 24% built-upon area (BUA) for all residential and non-residential development. See Section 12.6.1.D for the Low Impervious Surface limits for areas located in protected watershed such as Falls Creek, Richland Creek, and Smith Creek. MAINTENANCE (WTF) Plumbing, electrical or mechanical work that may require a building permit but that does not constitute a Modification to the WTF. MANUFACTURED HOME (FLOODPLAIN DEVELOPMENT) A structure, transportable in one or more sections, which is built on a permanent chassis and designed to be used with or without a permanent foundation when connected to the required utilities. This term does not include a “recreational vehicle”. MANUFACTURED HOME PARK OR SUBDIVISION (FLOODPLAIN DEVELOPMENT) A parcel (or contiguous parcels) of land divided into 2 or more manufactured home lots for rent or sale. MARKET VALUE (FLOODPLAIN DEVELOPMENT) The building value, not including the land value and that of any accessory structures or other improvements on the lot. Market value may be established by independent certified appraisal; replacement cost depreciated for age of building and quality of construction (Actual Cash Value); or adjusted tax assessed values. MEAN SEA LEVEL (FLOODPLAIN DEVELOPMENT) The National Geodetic Vertical Datum (NGVD) as corrected in 1929, the North American Vertical Datum (NAVD) as corrected in 1988, or other vertical control datum used as a reference for establishing varying elevations within the floodplain, to which Base Flood Elevations
LOT LINE A line forming a boundary of a lot.
LOT LINE, PRINCIPAL FRONT A lot line separating the lot from the public street right- of-way or private street. On a lot with more than one street frontage, the principal front lot line is generally the lot line abutting the street of higher classification. If both streets have the same classification or in the case of infill development, the principal front shall be the lot line that continues the established building pattern. LOT LINE, REAR A lot line connecting the lot’s interior side lot lines, or an interior side lot line and a street side lot line, along the edge of the lot opposite its front lot line. LOT LINE, SECONDARY FRONT OR STREET SIDE A lot line, other than a principle front lot line, separating the lot from an abutting public street right-of-way or private street. Generally, the street side or secondary front lot line is the lot line abutting a street of lower classification. LOT LINE, SIDE A lot line not abutting a street and connecting the lot’s front and rear lot lines. LOWEST ADJACENT GRADE (LAG) (FLOODPLAIN DEVELOPMENT) The elevation of the ground, sidewalk, or patio slab immediately next to the building, or deck support, after completion of the building. LOWEST FLOOR (FLOODPLAIN DEVELOPMENT) The lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access, or limited storage in an area other than a basement area is not considered a building's lowest floor, provided that such an enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of this ordinance.
