Parcel #
A legally defined piece of real property, typically represented by a surveyed plot of land with specific boundaries and ownership.
Smart Growth #
An urban planning approach that promotes compact, walkable, mixed-use development with easy access to public transportation, in order to reduce automobile dependence and promote sustainable communities.
Site Analysis #
The process of evaluating a potential development site's physical, environmental, and regulatory characteristics to determine its suitability for a specific project.
Transfer of Development Rights (TDR) #
A zoning technique that allows property owners to sell development rights from their land to another property owner, often in exchange for preserving open space or historic resources.
Urban Growth Boundary (UGB) #
A clearly defined boundary that separates urban and rural land uses, limiting urban expansion and preserving open space.
Variance #
A legal mechanism that allows a property owner to deviate from the strict application of zoning regulations, typically granted for specific, compelling reasons and subject to certain conditions.
Zoning #
The regulation of land use and development through local laws and ordinances, designed to promote orderly growth, protect property values, and ensure public health, safety, and welfare.
Zoning Overlay #
A zoning district that overlays an existing zoning district, imposing additional or modified regulations on a specific area within a community.
Zoning Regulations #
The specific rules and requirements that govern land use and development within a zoning district, such as setbacks, height limits, lot coverage, and building types.
Conceptual Site Design #
A preliminary plan for the layout and configuration of a development site, including building placement, open space, infrastructure, and access.
Due Diligence #
The process of investigating and evaluating a property's physical, environmental, and regulatory conditions prior to purchase or development.
Easement #
A legal right to use someone else's land for a specific purpose, such as access, utility lines, or drainage.
Entitlements #
The legal approvals and permits required to develop a property, typically including zoning variances, conditional use permits, and environmental clearances.
Grading #
The process of reshaping the land surface to accommodate a development, including cutting, filling, and compacting soil.
Infrastructure #
The basic physical and organizational structures needed for the operation of a community or development, including roads, utilities, and public services.
Site Plan #
A detailed, scaled drawing that shows the layout and configuration of a development site, including buildings, open space, circulation, and infrastructure.
Subdivision #
The process of dividing a large parcel of land into smaller lots for development, subject to local regulations and review.
Urban Design #
The art and science of creating functional, aesthetically pleasing, and sustainable public spaces and communities.
Yield Analysis #
A study of the potential number of housing units or building square footage that can be developed on a site, based on zoning regulations, site constraints, and design considerations.
Example #
Site Analysis and Design Process:
Suppose a developer is considering the purchase of a 5 #
acre parcel in a suburban community for a mixed-use development with retail, office, and residential components. The following steps outline a possible site analysis and design process:
1 #
Conduct a due diligence investigation of the property, including a review of title documents, zoning regulations, and environmental reports.
2 #
Perform a site analysis to evaluate the property's physical, environmental, and regulatory characteristics, such as topography, soil conditions, drainage patterns, solar orientation, views, and access.
3 #
Identify any constraints or opportunities presented by the site analysis, such as steep slopes, wetlands, or proximity to public transportation.
4 #
Research the community's general plan and zoning regulations to determine the property's allowed uses, densities, and development standards.
5 #
Consider any overlay districts or design guidelines that may apply to the property, such as historic preservation or urban design standards.
6 #
Develop a conceptual site design based on the property's physical characteristics, development potential, and community context, including building placement, open space, circulation, and infrastructure.
7 #
Conduct a yield analysis to determine the potential number of housing units or building square footage that can be developed on the site, based on zoning regulations, site constraints, and design considerations.
8 #
Prepare a site plan and other necessary documentation to obtain entitlements and permits for the proposed development.
9 #
Collaborate with community stakeholders, such as neighbors, business owners, and public officials, to address any concerns or issues related to the proposed development.
10 #
Refine the site design and prepare construction documents based on feedback from stakeholders and regulatory agencies.
Practical Application #
Urban Infill Development:
Urban infill development presents unique challenges and opportunities for site a… #
For example, a developer may be considering the redevelopment of a vacant or underused industrial site in an urban area for a mixed-use project with residential, retail, and office components. The following considerations may be relevant for the site analysis and design process:
1 #
Assess the site's access to public transportation, bike lanes, and walkability, and consider incorporating sustainable transportation options into the design.
2 #
Consider the potential for contamination from previous industrial uses, and develop a plan for environmental remediation or mitigation.
3 #
Evaluate the site's potential for solar energy, green roofs, or other sustainable design features.
4 #
Research the community's preferences and expectations for urban infill development, and consider incorporating public art, placemaking, or other community amenities into the design.
5 #
Consider the potential for adaptive reuse or historic preservation of existing buildings or structures on the site.
6 #
Evaluate the site's potential for stormwater management, such as rain gardens, bioswales, or green infrastructure.
7 #
Consider the potential for shared parking or other innovative transportation solutions to reduce the need for parking and promote sustainability.
8 #
Develop a plan for community engagement and outreach, and consider partnering with local organizations or businesses to promote the project.
Challenge #
Balancing Density and Context:
One of the key challenges in site analysis and design is balancing density and c… #
In other words, how can a developer create a dense, walkable, and sustainable development while also respecting the character and scale of the surrounding community? This challenge may be particularly relevant in urban infill development, where new projects must often fit into established neighborhoods with unique architectural styles, building types, and streetscapes. To address this challenge, developers may consider the following strategies:
1 #
Conduct a thorough context analysis of the surrounding community, including its history, character, and architectural style.
2 #
Engage with community stakeholders, such as neighbors, business owners, and public officials, to understand their preferences and concerns.
3 #
Develop a design
