BE IT THEREFORE ORDAINED BY THE BOARD OF COUNTY COMMISSIONERS OF PASCO COUNTY FLORIDA, as follows:

 

Section 1.   Short Title

 

This ordinance shall be known and may be cited as the “Pasco County Landscaping and Irrigation Ordinance.”

 

Section 2.   Authority and Power

 

Pursuant to the Constitution of the State of Florida and through Florida Statutes Chapter 125.66, the Board of County Commissioners is vested with the authority to adopt the Pasco County Landscaping and Irrigation Ordinance to be administered by the County Administrator, or his designee.  This ordinance shall be effective in the unincorporated areas of Pasco County.

 

Section 3.   Purpose and Intent

 

It is the purpose and intent of this Ordinance to promote the health, safety, and general welfare of the current and future residents of Pasco County by establishing minimum standards for the development, installation, maintenance and preservation of water-efficient landscaping and irrigation within Pasco County.  In support thereof the Board of County Commissioners hereby makes the following findings of fact:

 

A.                 As the Southwest Florida Water Management District Executive Order SWF 01-14 requires Pasco County to implement an ordinance requiring water-efficient and drought tolerant landscapes and efficient landscaping irrigation designs for new development; and

 

B.                As the Comprehensive Plan mandates that Pasco County implement a water conservation plan, and require the use of native plant species in the landscaping of new developments and additions to existing projects, and require the use of XeriscapeTM principles in landscape design and installation; and

 

C.                As the preservation of existing plant communities, the use of site specific plant materials, the use of pervious paving materials, the use of water efficient irrigation and other environmentally sensitive site development concepts help reduce water consumption; and

 

D.          As plant materials purify and cool the ambient air, provide shade, conserve energy, reduce noise levels and glare, and are aesthetically pleasing, plant materials are an invaluable amenity and asset to Pasco County.  Therefore, land management practices and land use techniques that require planting of plant materials is consistent with the Comprehensive Plan; and

 

E.                 As the use of plant materials improves the aesthetic appearance of public, commercial, industrial and residential areas by reducing the visual impact of large building masses, by softening the visual impact of paved surfaces and vehicular use areas and by screening conflicting uses from one another and otherwise helps establish a harmonious relationship between the natural and built environment; and

 

F.                 In order to protect and enhance the overall environmental quality and aesthetic appearance of Pasco County, the development, installation, and maintenance of water-efficient landscaping and irrigation must be regulated by this Ordinance.

3.       Type C buffer – A twenty foot (20’) wide buffer planted with two staggered rows of trees with a maximum spacing of thirty feet (30’) on center.  A visual screen designed to be  eighty percent (80%) opaque within one year and a minimum of six feet (6’) in height at installation shall also be provided within the buffer.  The screen may include a wall, hedge, berm or any combination thereof. 

 

4.       Type D buffer (Right-of-way buffer) – A landscape buffer shall be required adjacent to any road right-of-way external to the development project and adjacent to any primary access roads internal to a commercial development. 

 

a.                 The minimum width of the right-of-way buffer shall vary according to the ultimate width of the abutting right-of-way as indicated below:

 

i.        A right-of-way width of 0-99 feet requires a minimum ten-foot (10’) wide buffer.

 

ii.       A right-of-way width of 100 or more feet requires a minimum fifteen foot (15’) wide buffer.

 

iii.      Developments of 15 acres or more require a minimum twenty foot (20’) wide buffer regardless of the width of the right-of-way.

 

b.                  Shade trees shall be planted with a maximum spacing of twenty-five feet (25’) on center.  Palms shall be limited to landscaped areas adjacent to vehicular access points and shall be planted in clusters with a minimum of three (3) palms per cluster with a maximum spacing of eight feet (8’) on center.   Exceptions will be made for Phoenix spp. (not including roebelenii), which may be planted individually.  A maximum distance of twenty-five feet (25’) shall be maintained between all types of tree plantings.  The remainder of the buffer shall be landscaped with shrubs, at a minimum rate of five (5) shrubs per tree or palm, and groundcover. 

 

c.                   Where a vehicular use area abuts the right-of-way buffer, the buffer shall contain an earthen berm, a minimum of eighteen inches (18”) in height and shall be landscaped with shrubs and groundcover.  The berm and landscaping shall be eighty percent (80%) opaque and shall be a minimum of four feet (4’) in height at the time of planting and at all times thereafter.  A berm shall not be required within the visibility triangle areas for any driveways or pedestrian walkways.

 

d.       All portions of each site, which are not devoted to buildings, sidewalks, paving or special landscape features shall be grassed.  The use of native plant species and xeriscaping shall be encouraged.  However, no more than thirty percent (30%) of the required landscape area may be grassed, the balance shall be landscaped in shrub and ground covers.  All yard grass planted shall be Hybrid Bermuda or St. Augustine.
