LOT: A parcel or tract of land.
LOT, CORNER: A lot located at the intersection of two (2) streets which has a street frontage in excess of one hundred feet (100') as measured along the street lot line.
LOT, DOUBLE FRONTAGE: A lot having frontage on two (2) nonintersecting streets, as distinguished from a "corner lot".
LOT FRONTAGE:
   (A)   For lots with two (2) "side lot lines", "lot frontage" shall be that uninterrupted linear or curvilinear extent of a lot line measured along the street right-of-way from the intersection of one "side lot line" to the intersection of the other "side lot line".
   (B)   For lots with one (1) “side lot line”, where the “street lot line” is generally curved along the intersection of two (2) streets, “lot frontage” shall be measured tangentially along the narrower street lot line according to the following method, as illustrated in figure 14, “Lot Frontage,” of this definition.
      1.   Using each existing interior lot line, project a parallel line to the opposite street side, tangent to the outermost point of that street lot line.
      2.   Measure the length of each projected line from the point at which the two (2) projected lines intersect to the point at which each projected line intersects the interior lot line. The shorter of the two (2) projected lines shall be considered to contain the shorter "street lot line". The length of this shorter projected line shall be considered to be the "lot frontage" dimension.
Figure 14
Lot Frontage
 
To measure "lot frontage":
   (A)   Using existing interior lot line 1, project a parallel line to the opposite street side, tangent to the outermost point of that street lot line (tangent point A).
      1.   This creates projected interior lot line 1.
   (B)   Using existing interior lot line 2, project a parallel line to the opposite street side, tangent to the outermost point of that street lot line (tangent point B).
      1.   This creates projected interior lot line 2.
   (C)   Measure the lengths of projected interior lot lines 1 and 2 from the point of intersection of these two (2) projected lines to the intersection with each existing interior lot line.
      1.   In example 1, both existing interior lot lines need to be extended to intersect the projected interior lot lines (point C).
      2.   In example 2, existing interior lot line 1 needs to be extended to intersect projected interior lot line 2 (point C). In example 2, tangent point A serves as the point of intersection between existing interior lot line 2 and projected interior lot line 1.
   (D)   The shorter of these two (2) lines is the "lot frontage" dimension; in both examples, projected interior lot line 1 is the "lot frontage" dimension.
LOT, INTERIOR: A lot other than a "corner lot" or "double frontage lot".
LOT LINE, INTERIOR (Residential Districts): An "interior lot line" is any lot line not abutting a street.
LOT LINE, REAR (Residential Districts): The "rear lot line" is the lot line opposite and most distant from the street lot line. The "rear lot line" on irregular, triangular or gore lots shall, for the purpose of this zoning ordinance, be a line entirely within the lot at least ten feet (10') long, and parallel to, and most distant from, the street lot line. On a "corner lot", the "rear lot line" shall be opposite the narrower "street lot line". (See figure 15, "Rear Lot Line", of this definition.)
Figure 15
Rear Lot Line
 
LOT LINE, SIDE (Residential Districts): A "side lot line" is any lot line that is not a "street lot line" or "rear lot line". A "side lot line" separating a lot from another lot is a "side lot line". On a "corner lot", the "side lot line" shall be opposite the longer "street lot line". A lot line separating a lot from a street is considered a "street lot line". (See figure 16, "Side Lot Line", of this definition.)
Figure 16
Side Lot Line
 
LOT LINE, STREET (Residential Districts): The "street lot line" is a lot line that abuts a street. Corner lots may have more than one street lot line. If a portion of any lot is subject to an easement for public purposes, including, but not limited to, street, parkway and/or sidewalk, the street lot line will be deemed to be the line that separated that part of the lot subject to the easement for public purposes from that part of the lot not subject to that easement. (See figure 17, "Street Lot Line", of this definition.)
Figure 17
Street Lot Line
 
LOT OF RECORD: A lot that is part of a recorded subdivision or a parcel of land that has been recorded at the County Recorder's Office containing property tax records.
LOT WIDTH: The average lot width dimension shall be determined by adding the width of the lot at the required "street yard" setback dimension, as determined by subsection 10-4-3(D) of this zoning ordinance, and the width of the lot at the required "rear yard" setback dimension, as determined by subsection 10-4-3(E) of this zoning ordinance, and dividing that number by two (2).
   (A)   In the case of a lot defined by two (2) “side lot lines”, a lot axis shall be drawn from the midpoint of the “street lot line” to the midpoint of the “rear lot line”, and the setback dimensions shall be drawn at a right angle to that axis (see figure 18, “Lot Width,” example 1 of this definition).
   (B)   In the case of a lot defined by one (1) “side lot line”, the setback dimensions shall be drawn at a right angle from the “side lot line” to the intersection with the longer “street lot line” at the required setback dimensions (see figure 18, “Lot Width,” example 2 of this definition). The longer “street lot line” shall be determined by the projection of each interior lot line in parallel until it is tangent to the outermost point of the street lot line, as shown in figure 14 of the “lot frontage” definition in this section. The longer of the two (2) projected lines, which are parallel to interior lot lines, shall be considered to contain the longer “street lot line”. In the case of projected lines that are equal in length, the Zoning Administrator shall make the decision, based on lot shape, as to which of the “street lot lines” shall be considered the longer “street lot line” and used to determine “lot width”.

Roosevelt in 1935, provided jobs and income to the unemployed during the Great Depression, including community service projects, such as collecting and managing historical records. The WPA undertook a house setback survey in Riverside between 1936 and 1953, which documented building placement on Riverside's lots. This survey is entitled "Riverside, Illinois WPA Planning Project #9559 House Set Back Survey" pages 1 through 17. The information contained in this survey is available from the Village Building Department and is used to determine "street yard" dimension.
