Subdivision Modifications. When a Subdivider can show that a provision of this Chapter would cause unnecessary hardship if strictly adhered to, and when, in the opinion of the Commission, because of conditions peculiar to the site, a departure may be made without destroying the general intent and spirit of the provision, the Commission may recommend a modification to the Board. The Subdivider shall apply in writing for such modification within the Preliminary Plat application. Any such modification thus recommended shall be entered in writing in the minutes of the Commission, and the reasoning on which the departure was justified shall be set forth. Approval of the modification by the Board shall be by ordinance and may be part of the ordinance approving the Preliminary Plat.
Landscape
A. It is the purpose of this Section to provide reasonable minimum standards for the preservation of areas of natural tree cover and other unique characteristics of the landscape within the City, to facilitate new development in harmony with intrinsic environmental values, establish appropriate Buffers Areas between various development types and individual Lots, encourage interspersion of landscaped nodes within Off-Street Parking Areas, and to, in an orderly manner, establish a visually pleasing and functional streetscape.
1. General landscape requirements.
a. Trees generally. No tree shall be planted closer than forty (40) feet from any Intersection corner measured from the Front Lot Line or the point of intersecting Front Lot Lines. No tree shall be planted closer than ten (10) feet from any fire hydrant.
b. Pruning requirement. Every owner of any tree overhanging any Street in the City shall prune the branches so that such branches shall not obstruct the light from any Street lamp or obstruct the view of any Intersection and so that there shall be a clear space of eight (8) feet above the surface of the Street or sidewalk.
c. Unlawful to damage City landscaping. It shall be unlawful for any person to cut any tree on public property or on public Streets except in accordance with Chapter 510, Excavations and Public Rights-Of-Way Management, or as otherwise specifically authorized by this Code or the Board.
d. Maintenance. Any unpaved areas between the Street and the abutting Lot shall be maintained to the finished curb line of the Street by the owner or occupant of the abutting Lot.
e. Vacant Lots or open spaces. Any vacant Lot or open space not being used for any purpose shall be seeded or sodded to maintain ground cover.
f. Tree removal on undeveloped land. No clearing of trees on undeveloped land shall occur until a permit has been obtained through the Community Development Department. The Director may require the submittal of a Conservation Plan as described under Subsection (B)(4), to be submitted for review and approval by the Director. Clearing of undeveloped land does not include the removal of underbrush or invasive species.
g. Tree removal near riparian. No trees shall be removed within twenty-five (25) feet of the riparian (stream bank) corridor without obtaining a permit from the Community Development Department. Tree removal does not include the removal of underbrush.
B. Landscape requirements for development or changes to land. Anything in this Code to the contrary notwithstanding, all development or changes to Property shall comply with the provisions of this Section.
1. Landscape requirements, in general.
a. Grade. The grade of land within the dripline of a tree designated to remain shall not be raised or lowered more than six (6) inches unless a well or Retaining Wallis used.
b. Tree protection during construction. Suitable protective barriers shall be erected around all trees to be preserved to ensure that the trunks, branches, and roots are not damaged during development.
c. Preservation of existing trees. An effort should be made to preserve the natural vegetation, tree cover, or other special landscape characteristics and to maintain any natural amenity which contributes to distinguishing the Property as an attractive setting.
d. Lawns.
(1) The following areas shall be considered as lawn:
(a) Lot Areas located sixty (60) feet from any Front Lot Line; and
(b) Areas from a Front Lot Line to any adjacent Street pavement.
(2) Lawns areas shall be established with a high-quality sod blend and not by seeding, unless the lawn area is otherwise already improved with trees, shrubs or other support landscaping, or sidewalks.
2. Required landscape for new Residential Lots.
a. There shall be at least two (2) trees planted in the Front Yard(s) of each Lot.
b. For any Attached Single-Family Dwelling development or within any Multiple-Family Dwelling development one (1) shade tree shall be planted per sixteen hundred (1,600) square feet of Gross Floor Area of each Building. The Commission may recommend the Board require evergreen trees as a Buffer Area between Multiple-Family Dwellings and adjacent Lots containing Single-Family Dwellings.
3. Required landscape for Non-Residential Lots. As Non-Residential developments are commonly characterized by larger Buildings, more extensive intensity of use and Lot coverage including sizeable Off-Street Parking Areas, additional landscaping should be considered. Thus, to help assure implementation of the objectives of this Section, the following standards will also be applicable to any new Building or Building additions in any Non-Residential District or any Institutional Building in any Residential District.
a. Use of preserved wooded or natural areas. The use of the wooded or natural areas for walking paths, picnic areas, and bench placement is encouraged. The layout of paths will be clearly defined by gravel or Asphalt or by defined edges of stone, timber, or plantings. Areas for picnic tables and benches will be distributed as to prevent the concentration of use in any single part of the wooded area. The intent of these requirements is to avoid compaction of ground surfaces at the bases of trees and to preserve the natural undergrowth.
b. Requirements of Lot landscaping. The owner or occupant must install landscaping for any new Building or area effected by any Building addition subject to these regulations and in accord with the following:
(1) Landscaping shall be required in all Buffer Areas that are not otherwise used for Off-Street Parking Areas, as provided in the Zoning District, except no formal landscaping shall be required in a rear Buffer Area that is unpaved except that a dust-free surface shall be maintained. However, in the event that the Rear Lot Line abuts a "R," "PG," or "PR" District, the Buffer Area shall be landscaped. Such landscaped area shall contain trees and/or shrubs that provides an opaque barrier, in the discretion of the Director not less than seven (7) feet in height or combination thereof.
(2) Each separate interior landscaped area with an area of one hundred (100) square feet or more shall include at least two (2) deciduous shade trees. Also, no tree planting area shall be less than six (6) feet in any dimension.
(3) All Lots used for Non-Residential Uses and abutting a Lot in a Residential District or Lot with a Residential Use shall provide along any common Lot Line a continuous berm with a minimum height of four (4) feet or planting of evergreen trees or shrubs approved by the Board to prevent the direct light from motor vehicle headlights from being cast on adjacent Residential Dwelling Units.
c. Off-Street Parking Areas. To reduce the apparent size of Off-Street Parking Areas, landscape islands shall be provided for all Off-Street Parking Areas with twenty (20) or more Off-Street Parking Spaces and a minimum of five percent (5%) of the total square footage of the Off-Street Parking Area shall be landscaped. Such islands shall be a minimum of eighteen (18) feet in length by ten (10) feet in width. One (1) such island shall be installed and maintained for each twenty (20) Off-Street Parking Spaces provided on the Lot and at the terminus of each row of Off-Street Parking Spaces adjoining an access drive. With the approval of the Board, landscaped areas may be substituted in lieu of landscaped islands that equal ten percent (10%) of the total Off-Street Parking Area (less Driveway and Drive Aisles). This shall be in addition to any other required Buffer Areas or landscape requirements.

Computations.
A. The following principles shall control the computation of Sign Face and Sign height:
1. Computation Of Sign Face Of Individual Signs. The area of a Sign Face shall be computed by measuring the area of the smallest circle, square, rectangle, triangle, or combination thereof that will encompass the extreme limits of the writing, representation, emblem, or other display, together with any material or color forming an integral part of the background of the Sign or used to differentiate the Sign from the back drop or Sign Structure against which it is placed, but not including the Sign Structure or Facade that is clearly incidental to the display itself.
2. Computation Of Multi-Face Signs.
a. A Double-Faced Sign with two (2) Sign Faces shall be considered one (1) Sign. Provided, however, to the extent a Double-Faced Temporary Sign has two (2) Sign Faces that are not identical, each Sign Face shall be considered a separate Sign and the area shall be computed by adding together the area of each non-identical Sign Face.
b. The Sign area for a Sign with more than two (2) Sign Faces shall be computed by adding together the area of all Sign Faces on the Sign.
3. Computation Of Height. The height of a Sign shall be computed as the distance from the base of the Sign Structure at normal grade to the top of the highest attached component of the Sign. Sign height of a Wall Sign shall be computed as the distance from the base of the Sign to the top of the Sign. Normal grade shall be construed to be the lowest of: (a) existing grade prior to construction or (b) the newly established grade, after construction, exclusive of any filling, berming, mounding, or excavating solely for the purpose of locating the Sign. In cases in which normal grade cannot reasonably be determined, Sign height shall be computed on the assumption that the elevation of the normal grade at the base of the Sign is equal to the elevation of the nearest point of the crown of a Street or the grade of the land at the principal entrance to the Principal Structure on the zoned Lot, whichever is lower.
