Crime Prevention Considerations for Landscaping and Plant Growth

April 23, 2013

Spring is here and planting and maintaining your garden plays an important role in preventing certain types of crimes. If not carefully controlled and thoughtfully designed, plant growth and landscapes can provide hiding places for persons with criminal intent.  Improperly planned and maintained landscaping can possibly create an environment that’s conducive to crime and entice illegal activity to the property.

The following recommendations are intended to address security issues associated with landscaping and plant growth:

Ground Cover Plants

Location

      As an alternative to shrubbery or other dense plant growth, ground cover plants, perennial and/or annuals, should be used for landscaping within six (6) feet of the edge of walkways, parking lots and building entryways or other areas requiring visual surveillance.

Height

      The height of ground cover plants should not exceed two (2) feet at maturity. Plants with thin stalks over two (2) feet high that still allow for good visual surveillance may be used in these areas.  Overgrown vegetation invites crimes. 

Shrubs

Location

      In addition to ground covers and appropriately pruned trees, shrubs may be used between six (6) and twelve (12) feet from the edge of walkways, parking lots and building entryways.

Height

     The height of landscape shrubbery should not exceed three (3) feet at maturity.

              Anything over 3 feet provides concealment. 

Barrier Plants

Location

      Barrier plants have thorns or needles and often a dense structure. They can be used below and near windows to discourage access. They can also be used adjacent to fences or building walls. Among such popularly-used barrier plants are Pyracantha, Agrave, Barberry, Natal Plum, Yucca, Hedgehog or Porcupine Holly. Even if placed below windows, these plants should be trimmed below the height of the windowsills. 

Height

      Since the purpose of barrier plants is to discourage pedestrian access, it may be acceptable for   them to exceed three (3) feet in height in some applications. 

Trees

Location

      Trees should be located or trimmed so as not to serve as a climbing aid to upper levels of homes or buildings or as a climbing aid over fencing or perimeter barriers. Trees should also not be placed where their foliage obscures roadway, walkway, or parking lot security lighting. If trees are located in these areas, they should be thinned and trimmed on a regular basis.

Height

      Trees should be pruned so that their lowest foliage is no less than seven (7) feet from the ground surface. 

Landscaping Rock

• Location

           Landscape rock can be used as an effective alternative to ground cover or shrubs. Small    

           landscape rock can be used under windows or near entryways to create noise when    

           stepped on.
