(a) Each new subdivision City block tree lawn is to be planted with a single variety on both side of the street. Succeeding blocks may be assigned a different tree variety. Extremely long blocks may have a variety change in mid-block.
(b) The normal spacing between trees on the tree lawn is fifty feet. The exceptions to this rule would be the columnar types and small ornamentals such as upright crab apples, where the spacing could be reduced. Upright types are used mainly on narrow tree lawns or where there is minimal space for crown development.
(c) Trees shall typically be centered between the back of the curb and the street-side edge of the sidewalk. Some exceptions:
(1) Wide tree lawns allowing trees to be moved towards the sidewalk;
(2) Cul-de-sacs where no sidewalks will be installed;
(3) If utilities have installed a number of lines and cables immediately back of the curb.
(d) Trees planted along the tree lawn to the right or left of the approach to an intersection must not impede vision of pedestrians, bicyclists, street signs, and motor vehicles. Adequate line-of-sight distance must be given to tree lawn signs (school crossing, parking etc.) in order that the later sign clearance trimming can be kept to a minimum. Greater line-of-sight distances shall be provided at railroad crossings.
(e) New subdivision plantings are to be placed no closer than five feet from gas and water shut-offs, driveways, fire hydrants, and property lot lines. All utility companies must be notified prior to any new subdivision tree lawn planting. List all planting locations and note the depth of the planting holes and equipment to be used.
(f) Recommended street trees are listed in an official Shade Tree Commission publication guide available in the City Safety-Service Director’s Office. The mature height and spread of a given tree type will determine the planting distance from a street light. The developer should also consider height of overhead wires, tree lawn width, and soil types.
(g) Trees required to be planted by this section must be planted within two years of approval of the final subdivision plat by the City.
