This sketch illustrates the minimum landscape architectural requirements for a parking lot in Pueblo. Illustration by John Olson.

The most recent update to the Pueblo Municipal Code  is the requirement by the State of Colorado to have a landscape architect stamp for projects submitted to the City’s Building Department. The State of Colorado signed a bill with this requirement in 2007 which most municipalities, including Pueblo, have added to their ordinance.
Pueblo’s landscape performance standards can be found in the Pueblo Zoning Code in Sec. 17-4-7 (Landscape Performance Standards).
The standards set forth in Sec. 17-4-7 are applicable in the following zone districts: R-4, R-5, R-6, RCN, B-1, B-2, B-3, B-4, BP, PUD, H-B, I-1, I-2, O-1, CCN, S-1, S-4 and S-5. They are applicable for the following conditions:
1. New construction on any lot or placement of a structure on any lot
2. An addition of 35% of more of the gross square footage of an existing building
3. Use of 5,000 square feet or more for a contiguous off-street parking lot (not applicable if it is an improvement of parking lot that has been in use since before June 22, 1998).

One Tree and Five Shrubs shall be included for every 30-linear-feet of frontage. Illustration by John Olson.

Tree Spacing in Setback: ONE Tree AND FIVE Shrubs shall be provided for every THIRTY-linear-feet of frontage. Setback must be a minimum of 10-feet in width. 50% of the shade trees must be either evergreen trees or ornamental trees.

A Parking Island with 9-feet of width is necessary for the length of the parking stall for every 15 contiguous parking stalls in Pueblo. Illustration by John Olson.

Parking Lot Landscape Islands: A parking lot landscape island must be provided on the end of each bay of parking when FIVE or more regular parking spaces are included. Additionally, there shall be no more than FIFTEEN consecutive parking spaces (including head-to-head parking spaces, see sketch) without a landscape island. Islands must be a minimum of 9-feet in width and 18-feet in length (measured from the face of curb) and include at least ONE tree and FIVE shrubs.
Parking Lot and Drive-Through Screening: In addition to the frontage requirements, screening must be attained by the use of shrubs with a minimum height of 3-feet, a berm that measures 3-feet higher than the parking lot elevation, or an opaque structure (wall/fence) that is 3-feet in height placed at the setback.
Landscape Buffers (Between Residential and Non-Residential Land Uses): Buffer shall be at least 10-feet in width with at least ONE tree for every TWENTY-linear-feet AND an opaque fence or structure at least 6-feet in height.
The aforementioned standards are the key standards in Pueblo’s code. There are many other codes and standards applicable to the City of Pueblo, but understanding the standards above will assist the landscape architect in understanding the needs of a project in Pueblo.
