Literature Review

 

Abbey, D.G. Buck. U.S. Landscape Ordinances, John Wiley, NYNY, 1998.

 

Abbey’s study is the most current and most complete study of landscape codes and standards currently in print.  The book surveys ordinances from across the country, sets forth some of the known history of landscape codes and presents an outline model code that could be adapted by communities everywhere.  Abbey’s 1998 study of over three hundred and fifty landscape laws, in two hundred and ninety-nine communities, in forty-one states has defined the most common landscape design components and technical standards in use across America. The structure of the recommended model code is presented and the three main articles describe in detail the context, technical requirements and administrative procedures that make landscape laws work.   The book is well illustrated with diagrams, drawings and code excerpts to make the discussion lively, technically informative and place sensitive.

 

The book describes in detail the known vocabulary of this particular type of landscape law. Contacts to communities who have adopted landscape laws are detailed in one of the several appendices included in the book.

 

Many of the ideas and concepts of this presentation are documented in more detail in Abbey’s book that was published by John Wiley & Sons, Inc. The book which may be ordered direct from John Wiley Publishers at www.wiley.com or from The American Planning Association Book Service, www.bookservice@planning.org. or from Amazon.Com at www.amazon.com.

 

Abbey, D.G.. Guide To Writing A Landscape Ordinances, Louisiana Nursery and Landscape Association, Baton Rouge, Louisiana, 1987.

This is an early study of landscape codes that put together a model outline that could be used by any community wishing to draft a community landscape ordinance. The study was based on codes in effect at the time in the State of Florida with emphasis on a code developed by the South Florida Water Management District. The real contribution of this work is how it structures landscape codes.  Where most codes are writing in a rambling disjointed style, this model simplifies the outline in to three main articles consisting of fourteen (14) sections and many subsections. The three articles include context, technical requirements and administrative procedures.  The fourteen sections include short title, purpose-intent and definitions, applicability, land clearing, site and landscape design standards, maintenance, landscape plan required, alternative compliance, permit application, enforcement-penalty and appeals, administrative guidelines, conflicts, severability and effective date.

 

The document sets a structure for developing landscape codes that is readable, thorough and complete. Since this model was written, a lot of work has gone into tree preservation, water efficient landscaping and on site storm water management strategies much of which is not included in this model, but could be easily updated within the articles provide.

 

Bernhardt, E., Swiecki, T. Guidelines for Developing and Evaluating Tree Ordinances, California Department of Forestry, Sacramento, CA, 1991.

 

Swiecki surveys tree management and preservation ordinances to establish common ordinance provisions and to out line a process where by a community could craft a ‘ tree preservation ordinance consistent with their own particular needs.’ The paper sets forth typical tree ordinance components found the ordinances that were surveyed. Swiecki finds that most tree ordinances are crafted around several main articles including  scope, plan review, implementation and enforcement.  Sections of most typical tree ordinances found in the survey include title, findings, purpose, jurisdiction, policies, governmental liability, public interference, definitions, appeal, penalty, enforcement, evaluation, severability and administrative responsibility.

 

The study is the only recent study of the body of laws in regard to tree management. There is some concern that the ordinances studied were limited, some what dated and restricted to a local regions.  Further work along this line of research is needed to disclose some of the more progressive tree ordinance strategies that are measuring results along defined environmental limits such as canopy coverage, root zone spacing standards, caliper counts, tree protection measures and planting for specific site purposes.

 

Brough, M.. A Unified Development Ordinance, Planners Press, American Planning Association, Chicago, IL. 1985.

This document prepared by attorney and planning consultant Michael Brough provides a model unified development ordinance that combines elements of zoning, land use regulation, subdivision development and building code into one unified and concise planning document.

 

One of the interesting features of this model is the section dealing with landscape design guidelines and buffer zone planting requirements.  The former presents guidelines for landscape design that can be used to set technical standards for the design of street yards, buffer yards, open space plantings, street wall planting zones, vehicular use areas and parking lot screen. 

 

The buffer yard guidelines set forth a procedure that allows flexibility based upon site conditions. Buffer yard design standards offered in A Unified Development Ordinance suggests alternative buffer yard planting strategies, density standards, and spatial relationships based upon existing and proposed land use.  This method of “optional buffer yard design” have been adopted in many communities, perhaps Baton Rouge, Louisiana being the most noted community to do so.

 

Duerksen, C., Goebel, M., Aesthetics, Community Character And The Law, American Planning Association, APA Pass Report no. 489-490.1999.

 

This document reviews the relationship between design and municipal law from several different perspectives including design review, view shed protection, vegetation preservation, billboard imposition, telecommunications facilities siting and public aesthetics.  For our purposes, Chapter four covers the subject of interest to those wishing to craft local tree laws. Duerksen amplifies upon his earlier work on tree law, Tree Conservation Ordinances, by touching upon key legal issues of tree aesthetics and ownership by pointing out useful legal methods, strategies and approaches that should be incorporated into any local code to side step the ‘takings issue’ that becomes central to any tree protection ordinance covering plant material and vegetation on some one else’s property.  Of particular interest to this discussion are developer incentives such as landscape credits, zoning incentives, differential assessment, and land acquisition that are recommended to strengthen a community’s ability to protect vegetation resources.

 

 

Duerksen, C., Richman, S. Tree Conservation Ordinances, American Planning Association, APA Pass Report no. 446.1993.

 

This book is the most recent book that addresses the subject of tree ordinances. Duerksen and Richman discuss the value of trees in urban communities and present a solid argument based upon visual, aesthetic, environmental, health and economic benefits of trees and urban forests. Their argument is centered on quality of life issues and how trees and green spaces in the city add to pleasing urban living.

 

This discussion continues in Tree Conservation Ordinances by noting the several legal aspects of tree preservation including enabling legislation, the “takings” issue, the Rational Nexus test and the legal relationship of trees to developers, property owners, public agencies and  chartered utilities who are often are in conflict with trees. Legal case law is cited including such seminal tree law cases as Nollan v. California Coastal Commission, Allingham v City of Seattle and Miller v. Schoene for example.

 

Of course, no discussion on legal issues involved with trees would be complete without some discussion of the politics of tree conservation. In this book author clearly show what issues are at stake and which stakeholders are effected by tree legislation. They provide a compelling argument concerning how to properly prepare for the adoption of a local tree law. Good tips, procedures and ideas are presented to broker a campaign for enacting tree preservation legislation at the local level. Steps to be taken are presented, examples given and pit falls to be avoided are all documented in this very readable book.

 

Finally, the best part of Tree Conservation Ordinances is chapter four where the authors set forth guidelines for the proper drafting of an ordinance. They give information concerning how to effectively structure the ordinance and what to point of information cover in the various articles, sections and sub-sections of the ordinance. Useful background and suggestions are offered in regard to deciding what to protect and how, tree inventory methods, tree protection during construction, standards for permits and site inspections, maintenance, enforcement and administration. Sample definitions are provided along with a sample Tree Removal and Site Clearing Permit.

 

Hoefer, P., Himelick, E., Devoto, D. Municipal Tree Manual, Municipal Arborists And Urban Foresters Society and ISA, Urbana, IL. 1990.

 

This documents is very dated. It is listed here simply because it was one of the first studies to address the proper crafting of tree ordinances. At the time this was written, the emphasis in the model was placed on getting communities to regulate the local arboriculture industry and increase the competence of  professional arborists. Few communities today craft tree ordinances solely around the work of arborists.

 

 

Martz, Wendelyn, Morris, Marya. Preparing a Landscape Ordinance, American Planning Association, APA Pass Report no. 431.1990.

 

Martz -Morris’s study of landscape codes is one of the first documents ever published on the subject of landscape ordinances. In this APA Planning Advisory Service report Martz-Morris discusses the basic need for site development ordinances to solve land use problems. The study goes on to describe the fundamental design components of such ordinances. Common components defined for the first time include buffer yards, parking lot interior landscaping, landscape strips, parking lot perimeter plantings, commercial and industrial landscape strips along streets. The report goes on to describe residential landscaping for single family and multi-family developments consisting primarily of open space plantings, screens and buffers. Chapter three of the document provides guidelines on drafting an effective ordinance. Martz-Morris define thirteen (13) articles in a typical landscape code.  The include purpose, definitions, applicability, approval process, alternative compliance, plant substitutions, plan preparation submittal requirements, enforcement, maintenance, plant lists, landscape standards, and tree preservation during construction.  

This study was done when landscape codes when they were not commonly found in American cities. This document is one of the most important early studies in the field of landscape ordinance technology.  Much of the work of this study was developed from Prince George, County, Maryland.

 

 

Robinette, Gary. Local Landscape Ordinances, Agora Press, Plano, Texas, 1992

 

Robinette’s study of landscape codes is heavily weighted toward understanding the role that design and spatial relationship plays in the development of landscape codes.

 

 This study is a compendium of knowledge from landscape codes found in the Dallas, Texas area where both irrigation and planting requirements are typical components of any ordinance. The document studies all of the components of typical landscape codes in both text and drawing format.  Perhaps the greatest contribution of this work is the careful evaluation of twenty-nine (29) ordinance components in fifty-three (53) different communities. From this analysis the authors verified that the most common components of landscape codes were maintenance (64%), preparation of landscape plans (62%), screening of parking areas (56%), irrigation (52%), and  internal parking lot plantings (49%). Tree preservation is required in only thirty–two percent (32%) of the communities surveyed.

 

Although the study is somewhat disorganized, with no real understanding of ordinance structure, this important work documents the relationship between design and law in a very meaningful and readable way.

 

Wolfe, K. Trees, Parking and Green Law: Strategies for Sustainability, USDA Forest Service, Southern Center for Urban Forestry Research and Information, Athens, GA., 2004

Dr. Wolfe’s study of green laws related to parking lots and trees is one of the most current studies of landscape ordinances and their effect upon parking lot design, local climate and the heat island effect all of which are important concerns that modify living conditions in urban areas. This book was published in 2004 so the data is very current and her discussion on ‘code traditions’ is in support of Abbey’s work in U.S. Landscape Ordinances, mentioned elsewhere in this literature review.

 

Wolfe studies landscape law in regards to trees and parking.  The emphasis of her work is on the question of parking lot sustainability and how trees, shrubs, plantings, paving, drainage and parking lot geometry can be modified to effectuate environmental improvement. Her comments on green law innovation is notable. She points out issues associated with parking demand, parking lot sizing, tree preservation, canopy coverage, plant specifications and storm water management that are on the leading edge of research in the country in regard to sustainable parking.

 

_________________. ICC International Zoning Code, International Code Council, Falls Church, VA., 2003

 

The 2003 International Zoning Code contains uniform requirements for use districts and five zoning classifications, consistent zoning requirements that can be tailored to specific jurisdictional needs, and coordinated requirements and definitions related to the International Building Code. This document sets forth a real basic landscape code.  Chapter 8, section 805 sets forth basic landscape requirements that are followed by any community that adopts this standard code as their community zoning code. Additional requirements are found under planned unit development regulations.
