Introduction
LAND DEVELOPMENT, A PROCESS THAT IS BOTH AN ART AND A science, comprises a large number of interrelated parts. A clear understanding of how each part affects the other is one of the keys to successful project development. Equally important is the timely execution of each part related to the whole project. Awareness of the effects of the project's scope and timing produces an efficient process from start to finish. Developers also need to understand and incorporate the holistic nature of developing land into their plans and procedures. Developers should pay particular attention to how each separate part of the land development process affects the other parts to facilitate the desired outcome.
The land development process is continually evolving. Developers must be prepared to respond to fluctuating market trends, decreased land availability, more stringent regulations, and economic trends. The successful developer stays abreast of these social, economic, legal, and design factors. Because of the length of time involved in taking a new development from concept to sales, developers must anticipate changes in some of these factors. Predicting the lifespan of a current trend and forecasting future trends is not an exact science, but your success can be greatly improved through diligent research.
Figure 1.1 presents the broad work categories and corresponding tasks that make up the land development process. The development tasks may change in response to external conditions even though the broad categories tend to remain static.
Although this list is presented in a linear order, the land development process is not a linear one. The developer and the project team may have to retrace their steps at many points along the way. As new information becomes available, you must reconsider past decisions. This synthesis of information, in which you discard unworkable ideas and seek new conclusions, is the essence of the process. In a successful process, the developer makes the appropriate modifications of original impressions and decisions at various stages along the way.
Because you can approach the process from several different standpoints, where it begins influences the entire order. The approach advocated by this book begins by determining the best marketable idea for a given local area, followed by the search for the best site to accommodate that idea. If you have already acquired a parcel of land, the search begins with determining the highest use for the site. Another approach might begin with a search for a suitable site to support a previously determined marketable idea.
Once the site and the idea are placed together for serious consideration, the process of researching, analyzing, and synthesizing data to produce the final master plan remains virtually the same for each approach.
The Concept
The land development process commonly begins with a good idea for the creation of a new community, one that will serve its residents' needs and aesthetically coexist within the preexisting local urban or suburban area. The new development must prove economically viable for both the developer and the residents. To formulate a successful idea, the developer should begin with an understanding of the local marketplace and what the targeted buyer needs and wants in a new community. You gain this understanding by gathering and investigating all pertinent data.
You must employ three major categories of investigation to create a master plan for a new community on a selected site. Once you have formulated the concept, the first step is to research the existing conditions. The next step entails analyzing possible project constraints and opportunities based on the research. You then need to synthesize the results of your research and analysis into a coherent, functional plan that supports the original idea for the new community.
The investigation process involves market research, site selection and analysis, project design, site engineering, project cost, and financial feasibility. Each component plays a unique role.
Market research involves determining what type of buyers to target; understanding their buying power, lifestyle characteristics, and product demands; matching housing types and master plan concepts with those characteristics; and formulating the appropriate advertising and sales strategies.
Site selection and analysis involve developing a list of desirable site characteristics; discovering all the physical, regulatory, geotechnical, and social factors of a particular site; and analyzing the impact of those factors on the project's viability.
Project design matches marketing research with the site's innate characteristics to produce a master plan with housing types that reflect buyer preferences.
Site engineering encompasses the physical manipulation of the topography and installation of the infrastructure necessary to support the master plan concept.
Project costs include the soft costs (regulatory fees, marketing, investigation) and hard costs (labor and materials) of each work item. You must correctly forecast these costs and develop a schedule to complete each task so that you can produce an accurate cash flow for the project.
The project's financial feasibility is determined by its profitability, which is the result of actual sales minus project costs.
The Project Team
Land development requires input from a variety of disciplines. Assembling the right mix of professionals and consultants to provide the specialized knowledge required for the various aspects of creating a successful project will place you on the path to project viability. The primary members of the project team include a marketing professional, a financial professional, a project planner, and a design team..
The developer steers the project team. His or her primary responsibilities are to assemble and direct the team, determine the factors that each team member must investigate and analyze, reduce costs, and define the overall project goals to prevent duplication of work, gathering of unnecessary information, and increased costs. The developer should establish effective methods of communication and determine how the team will share information. Regular meetings should be scheduled to help the team stay focused.
The marketing professional's primary responsibilities are to identify the appropriate buyer, discern buyer preferences, and execute the advertising campaign and manage the eventual project sales. The financial planner determines the project's feasibility under various sales rate projections, factoring in all project costs. Marketing and financial analysis may be handled in-house or contracted out to a firm.
The project planner, or director of the project, might be an urban planner, architect, or landscape architect. Although one of these professionals might assume the leadership role, each would require input from the other disciplines. The project planner oversees the development of the conceptual master plan including marketing, financial feasibility, and design.
The civil engineer, another member of the design team, might be responsible for evaluating geotechnical conditions and determining infrastructure requirements. The most successful master plans result when the architect, landscape architect, and civil engineer work together to achieve the developer's vision for the new community.
At times, the developer may need to call in auxiliary project consultants to help create the master plan. These consultants might include hydrologists, geologists, soil scientists, environmental experts, construction managers, and attorneys among others. The size of the project, as well as the location of the site, will help determine the kinds of consultants needed. The project planner should determine the need for additional consultants, advise the developer about their respective roles, and coordinate the distribution of all information among the design team.
Although the developer must bear the expense of an expert project team up front, it can actually help keep down costs associated with proving project success and complying with a more complex regulatory climate in the long run. You cannot avoid the new project constraints created by the increased regulation of social and environmental impacts. However, a creative project team can help the developer find ways to turn project constraints into opportunities for new designs with increased market appeal.
Increasing Land Development Constraints
Land development remains a vital part of the U.S. economy as it enables local regions to provide housing and jobs for growing populations. However, an increasing number of legal and permitting issues have had a negative impact on land availability. Today developers must confront increased site work and construction costs; shrinking municipal budgets for providing community services, security, schools, and other infrastructure; and the public's growing concern about increasing sprawl and decreasing environmental quality. These trends make it more difficult for developers to acquire and attain zoning approval for new home construction, which in turn has a negative impact on housing affordability. These factors contribute to the overall dwindling supply of land available and approved for residential development and have produced an affordable housing crisis in many parts of the country.
To compound these problems, evidence suggests that heightened public scrutiny manifests in an organized attempt to influence the way land is developed. In general, the best land has already been developed, and much of the remaining land contains restrictive qualities that caused developers to pass on it in the first place. When the residential development boom first began, developers naturally chose sites that were optimally located and easily developed, instead of sites that had engineering problems or no available utilities. Therefore, developers today face problems that were relatively uncommon in the 1940s through the late 1970s. Yet, a great deal of the remaining land exists in prime locations and, if done correctly, is worth developing. These factors point to the increased necessity of discovering, analyzing, and synthesizing the critical marketing, financial, geophysical, regulatory, and social information to determine a project's success.
Today's buyers are more sophisticated about the issues involved in land development. They are seeking high-quality communities, not just housing. Therefore, developers must strive to preserve the natural features of the land where applicable and tailor their community design to promote and support a certain lifestyle. This type of quality-based approach will appeal to buyers and help to ensure a successful project.
The Effect of Social Changes on New Development Types
The next decade will be an exciting time for land development. Emerging niche markets offer a range of opportunities for developers. The 50+ demographic will continue to be a prime target, but that group's needs and desires differ from the same age-group 20 years ago. This group is working longer, living longer, more active, and eager to begin the new phase of their lives in which children and work will not come first. They are interested in self-improvement, physical fitness, and social and recreational activities. Chapter 1 will discuss the full range of emerging target groups along with their customer profiles.
Because of changing demographics, economic factors, and an increased dependence on new technologies, developers need to stay flexible. Flexibility can be especially helpful in determining site plan design, target market, and housing product. As the process of determining a market and choosing a site moves forward, you need to keep alternative uses and choices in reserve should sudden unforeseen changes occur. Unless you have a high level of confidence in your target market's viability, avoid selecting a site that is suitable for only one purpose.
New trends in social interactions, job types, and commuting preferences also serve to create a steady supply of new markets. Security issues, increasing fuel prices, and the cost of materials have also emerged as factors to consider. Town centered communities that are pedestrian friendly, have higher densities, are transit-oriented, and have mixtures of commercial and residential uses are making inroads into the previously dominant conventional suburban development form. One thing is certain: In the next decade, considerations for land development will be changing at a more rapid pace than ever before.
However, good timing, sharp instincts, an expert team, and innovative planning will play important roles in the process of creating a new community. The chance of success is greatly improved when the developer understands the full range of the land development process and the impact of each of the various components involved.
