Growing Greener: Putting Conservation into Local Codes.  This 18-page booklet summarizes the Growing Greener program in Pennsylvania (also called Conservation by Design).  It provides a brief distillation of the principal points discussed in my Growing Greener book (235 pages).  Although written in a Pennsylvania context, its principles are broadly applicable to readers in every state. This is an excellent condensation of the issues and of practical approaches for implementing key elements of a Smart Growth strategy in rural and suburbanizing areas.

Model Conservation by Design Ordinance for Pennsylvania (Growing Greener 2.0). This pdf contains model language for zoning and subdivision ordinances originally developed 15 years ago by me and others at the Natural Lands Trust for communities within Pennsylvania, and recently been updated by current staff. Although it has not been further modified to remove sections based specifically on Pennsylvania law, (statutes and court decisions), it provides an excellent starting point for planners and land-use attorneys interested in beginning with an excellent set of submission requirements, review procedures, and design standards. It is recommended that it be read in conjunction with the article entitled Flawed Processes, Flawed Results…, also available for free downloading in this section.

Conservation Design in the Chesapeake Bay Watershed. This 21-page booklet, which I wrote for the US Environmental Protection Agency, deals more deeply with the four-step design process for creating conservation subdivisions and focuses on water quality protection issues, a key component of “Low Impact Development” (LID). These design principles can be effectively applied toward protecting many other natural or cultural values important in the reader’s area. This publication is highly recommended.

Smart Development for Quality Communities. This extensively illustrated 48-page booklet contains four principal sections, two dealing with residential development issues (Rural Residential and Village Residential) and two dealing with commercial development issues (Highway Commercial and Village Commercial). It also contains several case studies focusing on conservation subdivision design and downtown storefront rehabilitation. Although I wrote this award-winning booklet for one county in western New York State, it is applicable to a wide range of communities, and in fact has been distributed to small towns across the state by the Lieutenant Governor’s Office. Its material is drawn from four of my books: Rural by Design, Conservation Design for Subdivisions, Growing Greener, and Crossroads, Hamlet, Village, Town (q.v.).

Land Use Planning in Britain and New England.This five-page article was written to prepare participants in an exchange program between land-use planners from Great Britain and the United States. It explains why certain fundamental regulatory mechanisms for controlling land use differ so dramatically between the two countries.

Flawed Processes, Flawed Results, and a Potential Solution. This short paper provides a constructive critique of outmoded subdivision regulations, and is applicable to almost every local planning jurisdiction in this country (and Canada). After describing the many extremely common flaws that seriously compromise the effectiveness of most subdivision regulations, I describe how these significant shortcomings can be easily addressed and corrected. A must-read.

Design Studies Portfolio. This brief publication which I prepared for the Natural Lands Trust describes and illustrates four designs I prepared at the request of municipal officials in southeastern Pennsylvania, who wanted to show developers better ways to subdivide land, plus three designs I prepared at the request of applicants. In addition, it contains a design done by another firm but according to the conservation design principles embedded in the subdivision ordinance and zoning ordinance that I had helped the municipality to write, and according to the Community-wide Map of Potential Conservation Lands that the Trust helped prepare for the Township.

Lopez Village Design Workshop. This file contains the summary report of a four-day design charrette I led on Lopez Island, WA. Although the design recommendations are important to the Village, the value to readers of this webpage is that it gives them insight into the interactive process (including pro-active outreach) that characterized the way I approached this project. To be successful, I feel that such undertakings must both solicit and elicit a very high level of public involvement.

Enhancing Subdivision Value through Conservation Design.  This article describes and illustrates the four-step design process for laying out subdivisions around the central organizing principle of land conservation. Originally published in On Common Ground, magazine of the National Association of Realtors.

Designing Traditional Neighborhoods around Natural Features. This article discusses some of the “greener aspects of the New Urbanism”, showing how Traditional Neighborhood Design (TND) principles can be blended with those of conservation design. It appeared in the Spring 2000 issue (No. 7) of, an on-line journal of the built and natural environments.

Intelligent Design: Green Space is Priceless in Subdivisions that Work with Nature.  Feature article describing the unique hands-on design exercise which is a hallmark of my conservation design workshops. This is where the learning curve rises steeply. When audiences are asked to lay out a conservation subdivision after listening to my illustrated lecture, they are forced to think more deeply about the special four-step design process which holds the key to successful design. They literally “learn by doing”, a far more fruitful educational experience than simply viewing slides and listening to verbal presentation. When their hands are connected with their brains, and when they discuss the design possibilities with others around their tables, their level of understanding increases dramatically, and they return to their communities and workplaces newly energized.

Cultivating Natural and Cultural Landscapes through Conservation Subdivision Design. A photo-essay that I wrote for the nation’s leading on-line magazine addressing land-use issues and showcasing creative approaches to managing growth. is a “Journal of the Built and natural Environments”, published quarterly, and accessible at This photo-essay presents two dozen images capturing different site features that have been saved through this common-sense design approach. Half are located in conservation subdivisions I have personally designed in various landscapes and regions from Maine to Minnesota, and from Texas to Florida. They include natural features, historic/cultural resources, restoration examples, community lands, and commercial uses of non-common open space.

CSD: A Brief Overview. This two-page summary distills the essence of conservation subdivision design, providing a handy, quickly-readable, precis of this creative approach to simultaneously conserving and developing land. Ideal as an introduction for busy people.


CSD: A Brief Overview

Conservation Design versus Typical Clustering. A workshop handout written by staff of the Natural Lands Trust in Media PA, where I developed the conservation-by-design approach called Growing Greener. It distinguishes conservation design from earlier “cluster” approaches which have generally failed miserably to produce their intended results. Learning from past mistakes, CSD avoids the pitfalls that have rendered cluster and PRD (or PUD) ordinance provisions functionally useless in terms of protecting meaningful open space.

From the Ground Up. A feature article describing a talk on the sustainability aspects of conservation subdivisions, delivered on Prince Edward Island in the Canadian Maritimes, but universally applicable. This kind of advance reporting helps to publicize such workshops and boost attendance, which was the goal of municipal staff when contacting the newspaper. To the extent that local reporters are willing to do this, workshop impacts can be maximized.
