2 TYPES OF DEVELOPMENT Residential: Single family, duplex, townhouse, apartments, and condominiums. Residential: Single family, duplex, townhouse, apartments, and condominiums. Commercial: Professional office, stores, malls. Commercial: Professional office, stores, malls. Industrial: single developments and industrial parks. Industrial: single developments and industrial parks. Recreational: Recreational: 1. Amusement - land use, local impact, access, liability, population supply. 2. Recreation - private clubs and sporting Parks – state and federal Parks – state and federal 3. Resorts – complete facility Use or ownership shared Use or ownership shared 4. Residential – incorporate a residential development around recreational site.

3 CONCEPTS AND ROLES OF THE LAND SURVEYOR Purpose of land development is to make the environment more useful and comfortable for humanity. Must be done in an organized and planned manner. Must be done in an organized and planned manner. Most often must be able to create a profit. Most often must be able to create a profit. Must meet political; economic; and aesthetics, while maintaining solid engineering principles. Must meet political; economic; and aesthetics, while maintaining solid engineering principles.

4 CONCEPTS AND ROLES OF THE LAND SURVEYOR Land Use Controls: exist to protect public health, safety and welfare. Land Use Controls: exist to protect public health, safety and welfare. Enabling Acts: passed in 1920s – federal laws permitting states to pass zoning and subdivision laws. Enabling Acts: passed in 1920s – federal laws permitting states to pass zoning and subdivision laws. Zoning Regulations: use of land-use controls to protect the rights of the individual property owner and rights of others with in the community Zoning Regulations: use of land-use controls to protect the rights of the individual property owner and rights of others with in the community 3 Basic areas: residential, commercial, and industrial 3 Basic areas: residential, commercial, and industrial Changed through exceptions and variances can occur – must shoe individual and public both benefit Changed through exceptions and variances can occur – must shoe individual and public both benefit

5 CONCEPTS AND ROLES OF THE LAND SURVEYOR Land Subdivision Regulations: Land Subdivision Regulations: State, county, municipal: Provides legal definition of a subdivision State, county, municipal: Provides legal definition of a subdivision Who can prepare Who can prepare Monument requirements Monument requirements Procedures for approval; design standards; construction requirements Procedures for approval; design standards; construction requirements Designed to protect individual to assure that access, utilities, drainage, open space, adequate building space, are all provided. Designed to protect individual to assure that access, utilities, drainage, open space, adequate building space, are all provided.

6 LAND SURVEYORS ROLE The role of the land surveyor varies depending on state – some on design (Indiana) The role of the land surveyor varies depending on state – some on design (Indiana) At minimum: boundary survey; create subdivision; topographic survey and construction stakeout. At minimum: boundary survey; create subdivision; topographic survey and construction stakeout. Can include: speaking for developer and limited design Can include: speaking for developer and limited design State dependent: horizontal and vertical street alignment; sanitary and storm sewer, etc. State dependent: horizontal and vertical street alignment; sanitary and storm sewer, etc.

7 STEPS FOR A LAND DEVELOPMENT PROJECT 1. Est. at least 2 nd order control traverse near boundary. 2. Complete boundary survey 3. Est. benchmark system 4. Prepare topographic map 5. Determine plan for streets, lots, utilities, etc. 6. Develop preliminary drawing 7. Obtain approval of preliminary design 8.

15 PLATTING PROCESS 1. PRE APPLICATION 2. PRELIMINARY PLAT 3. FINAL PLAT

16 RESIDENTIAL PLANNING CONCEPTS The actual planning of a subdivision is much more than just following a set of regulations. Development Concepts: Development Concepts: Traditionally individual lots for single family dwellings with access streets Traditionally individual lots for single family dwellings with access streets Other needs require dedication and each are zoned for single purpose Other needs require dedication and each are zoned for single purpose

17 RESIDENTIAL PLANNING CONCEPTS PUDs (Planned Unit Developments) PUDs (Planned Unit Developments) Integrated plan of residents, community shopping, recreation, open space, schools all mixed into small communities Integrated plan of residents, community shopping, recreation, open space, schools all mixed into small communities Requires changes in zoning concepts Requires changes in zoning concepts Generally large scope developments Generally large scope developments Neighborhood Unit concept: residential neighborhood created around a central focus Neighborhood Unit concept: residential neighborhood created around a central focus Pattern based on lot arrangement Pattern based on lot arrangement Conventional lot and block Conventional lot and block Lots and streets with no open or recreation areas Lots and streets with no open or recreation areas Most intense land use, small lots Most intense land use, small lots

18 RESIDENTIAL PLANNING CONCEPTS Cluster Development Cluster Development Lot and block system but side and/or back yard are developed for common parks or open spaces Lot and block system but side and/or back yard are developed for common parks or open spaces Must have home owners association to care for commons areas Must have home owners association to care for commons areas Pattern Based on Street Arrangement Pattern Based on Street Arrangement Street location can dictate lot pattern Street location can dictate lot pattern Rectangular – most common Rectangular – most common Lot and block with square corners Lot and block with square corners Pattern is visually monotonous and disregards topo Pattern is visually monotonous and disregards topo Easy to design and develop Easy to design and develop

19 RESIDENTIAL PLANNING CONCEPTS Curvilinear: similar to rectangular but streets are curved to fit topography Curvilinear: similar to rectangular but streets are curved to fit topography Relieved repetition, slows speed, overall development can meet terrain Relieved repetition, slows speed, overall development can meet terrain Radial: resembles spokes of a wheel Radial: resembles spokes of a wheel Useful if some central focus is needed or exists Useful if some central focus is needed or exists Can cause problems with triangular lots Can cause problems with triangular lots Linear: development along both sides of single road Linear: development along both sides of single road

21 RESIDENTIAL PLANNING CONCEPTS Loops and Cul-De-Sacs Loops and Cul-De-Sacs Loop – U shaped, Cul-de-sac Loop – U shaped, Cul-de-sac Used to minimize repetition in rectangular or curvilinear systems Used to minimize repetition in rectangular or curvilinear systems Also provides additional access Also provides additional access Can also be used to create small cluster communities within a development Can also be used to create small cluster communities within a development Coving and Bayhome Concept Coving and Bayhome Concept Purpose – developing land at a lower cost while creating superior communities Purpose – developing land at a lower cost while creating superior communities Provides more desired density Provides more desired density Increased safety Increased safety Decreased run off Decreased run off

22 COVING Coving combines both the bending of streets and setbacks creating more open space; generally the ROW is reduced 35% Coving combines both the bending of streets and setbacks creating more open space; generally the ROW is reduced 35% The Basics: The Basics: 1. Winding street pattern reduces or eliminates side streets and total number of individual streets 2. Lineal feet of streets typically reduced 20-40% while maintaining density and four way intersections minimized 3. Open space within entire community increased 4. Pedestrian walkways positioned to follow a curvilinear path separate from streets

23 COVING 5. Road remains at widths recommended 6. Layout reduces views of home sides or rears and homes rarely face another home front or rear which gives enhanced privacy 7. Streetscape consists of park like green space which meander from one side of the street to the other 8. Average lot size increases by 10-20% with extra typically in home fronts

32 BAYHOMING Bayhoming uses the same concepts as coving but with more density Bayhoming uses the same concepts as coving but with more density Coving is based on single family ownership, while with bayhomes the land and all items outside the home are held in common ownership with a homeowners association Coving is based on single family ownership, while with bayhomes the land and all items outside the home are held in common ownership with a homeowners association Coving incorporates townhouses in a staggered format Coving incorporates townhouses in a staggered format Requirements: Requirements: 1. Bayhomes have no individual lot, this allows for larger infrastructure reduction 2. While coving provides smooth curves with no staggering, Bayhomes can be greatly staggered creating more panoramic views from within homes 3. Parking is in rear with screened walls and landscaping hiding vehicles from public collector streets 4. Bayhomes have large front porches 5. Front of home is toward common areas

Superfund Amendment and Reauthorization Act of 1986 limits liability if proper investigations were performed as to existence of substances prior to purchase 3. Any indication of potential hazards means owner is liable

90 4 BASIC LAWS OF ECOLOGY 1. Everything is connected with everything else 2. Everything must go somewhere 3. Nature knows best 4. There is no such thing as a free lunch

91 ENVIRONMENTAL ASSESSMENT AND IMPACT STATEMENT NECESSARY TO: NECESSARY TO: 1. Predict any change in each environmental constituent 2. Identify the scope of any change on each environmental descriptor 3. Determine the implications or significance of the anticipated change on each element

92 5 COMPONENTS FOR ENVIRONMENTAL IMPACT 1. Environmental impact of the proposed action 2. Identify any adverse environmental effects which cannot be avoided 3. Range of feasible alternatives to achieve the initial problem objective or alternatives to the proposed action 4. Agency required to identify the relationship productivity 5. Requires agency to discuss the objections or issues raised by reviewers

93 INTENT OF IMPACT STATEMENTS 1. To provide a data base, documentation, and forecasts from which future decisions could be made. To identify the extent of both recognized and potential losses, the implications of the losses, and prepare information in such a way so it can e understood by government and public To identify the extent of both recognized and potential losses, the implications of the losses, and prepare information in such a way so it can e understood by government and public Many times developers would prepare their EIS into volumes with as much technical data as possible to try to get approval Many times developers would prepare their EIS into volumes with as much technical data as possible to try to get approval 2. EIS was to be a mechanism for integrated planning Often is used as a reason to justify decisions by governmental bodies Often is used as a reason to justify decisions by governmental bodies Tie projects up for so long as to make them impractical Tie projects up for so long as to make them impractical

94 2 WAYS ECOLOCY CAN BE USED AS A BASIS FOR PLANTING DESIGN 1. Essentially to guess what will work. 2. Plants are selected based on soil/climate, appearance and other relevant environmental determinants

95 3 DIVISIONS OF PLANT TYPES 1. CANOPY – those trees that define or limit overhead plane 2. UNDERSTORY – combination of small trees, large shrubs, and climbing vines under canopy trees 3. GROUND COVER – grasses, ground vines, and wildflowers

96 VEG. SHOULD BE EVALUATED BASED ON: 1. Aesthetic value 2. Disease resistance 3. Life span of trees 4. Wind firmness 5. Wildlife value 6. Comfort index 7. Ability to withstand higher radiated heat from paved surfaces and buildings 8. Future growth with respect to utilities

97 UTILIZING TREES IN WOODED AREA 1. These trees have shallow roots: may be best to conserve in clumps 2. Many mature trees will not survive a violent change of habitat. 3. Changes in ground water (amounts and quality) can cause problems 4. Area around trees should not be filled (disturbs access of air, water, and minerals)

98 ROLES OF PLANTS IN DEVELOPMENT 1. Wind control 1. Obstruction 2. Filtration 3. Deflection 2. Erosion control 3. Energy conservation 4. Wildlife habitat

99 PLANTING CAN BE USED: 1. In combination with buildings to extend architectural lines or as a screen to enhance architecture 2. As skyline 3. To define sheltered areas or act as buffer between activity areas 4. Enhance, blocks, frames, a view for building site 5. As educational source

100 PRINCIPLES TO CONSIDER WHEN DEVELOPING PLANTING PLAN: 1. Plan should reflect a predominance of one type of plant or a similar texture, color, or form within a grouping 2. Exercise restraint relative to the number of different plants used in plan 3. Select plants with common soil, climate, and water requirements 4. Maintenance of hedges is time consuming, consider growth habit and mature size 5. Develop plants so they do not rely on the quality of any particular tree or plant

101 PLANT SELECTION BASED ON AT LEAST ONE OF THESE CRITERIA: 1. Plants ability to live and flourish in the specific environment 2. Knowledge as to existing trees on site and their healthy growth on adjacent sites 3. Plants that require low maintenance and/or low water amounts 4. Plants for a specific purpose (shade, contrast, color, and size)

102 CLIMATE AND SITE THINGS THAT CAN BE DONE: THINGS THAT CAN BE DONE: 1. Develop exterior spaces that utilize local climate norms and extremes to expand availability of thermanlly comfortable outdoor areas 2. Reduce thermal loads on buildings

103 CLIMATE AND SITE FOUR BASIC CLIMATIC ELEMENTS FOUR BASIC CLIMATIC ELEMENTS 1. Solar radiation – reaches us in the form of direct, diffuse, and reflected radiation 4 methods of control and modification 4 methods of control and modification 1. Admission 2. Obstruction 3. Filtration 4. Reflection Vegetation: trees can absorb 60-90% of solar radiation Vegetation: trees can absorb 60-90% of solar radiation

104 CLIMATE AND SITE 2. Air temperature – only minimum changes can be caused – relative measure of thermal energy in the air Control and modification: by controlling solar radiation and air movement Control and modification: by controlling solar radiation and air movement Vegetation: air temperature is lowered due to evaporation process, but humidity levels increase. (this is often a small difference) Vegetation: air temperature is lowered due to evaporation process, but humidity levels increase. (this is often a small difference)

105 CLIMATE AND SITE 3. Relative humidity only minimum changes can be caused only minimum changes can be caused provide shade that does not limit air movement provide shade that does not limit air movement Humidity can be increased by including water in areas Humidity can be increased by including water in areas

106 CLIMATE AND SITE 4. Air movement – to utilize the beneficial effects must be aware of how site characteristics affect air motion Vegetation: when used to protect from cold winter winds it is a windbreak Vegetation: when used to protect from cold winter winds it is a windbreak Airflow is affected by shape and density of windbreak Airflow is affected by shape and density of windbreak Airflow is affected 5-10 times windbreak height on windward and up to 30 times height on leeward side Airflow is affected 5-10 times windbreak height on windward and up to 30 times height on leeward side

108 OUTDOOR WILDLIFE RELATED ACTIVITIES 2001 National Survey of Fishing, Hunting and Wildlife Associated Recreation 2001 National Survey of Fishing, Hunting and Wildlife Associated Recreation 1. Nationally $108 billion spent on wildlife related activities $108 billion spent on wildlife related activities 2. Illinois $1.35 billion spent $1.35 billion spent

109 DEVELOPMENT AND APPLICATION OF OUTDOOR RECREATION Recreation is often a delivery of opportunities for individuals and society most often provided by government Recreation is often a delivery of opportunities for individuals and society most often provided by government Benefits include: Benefits include: 1. Economic development 2. Protection or preservation of the resource 3. Education and learning 4. Maintenance or improvement of physical health

110 PROCESS FOR PLANNING 1. Determine which benefits are demanded from which areas 2. Determine the extent to which the resource base can be used to deliver benefits 3. Must take into account: budgets, technology, resource capability, current uses of resources, and non-recreational resource demands on area 4. Determine which management actions are to be used

111 FOLLOW UP ACTIVITIES 1. Monitoring the actions taken to determine if appropriate benefits are being developed 2. Monitor societies demands to see if original demands still exist Wildlife recreation planning manuals and handbooks are being developed by Bureau of Land Management and Forest Service Wildlife recreation planning manuals and handbooks are being developed by Bureau of Land Management and Forest Service

112 WHEN DEVELOPING A RECREATIONAL PLAN ONE SHOULD: 1. Estimate demand for possible recreational activities 2. Conduct capability analysis of land and water in plan area to determine potential of existing resources 3. Determine what recreational opportunities already exist on site 4. Conduct suitability analysis to determine where and how recreational activities should be provided

113 WHEN DEVELOPING A RECREATIONAL PLAN ONE SHOULD: 5. Incorporate recreational activities with other resource uses 6. Develop alternative use plans 7. Choose plan that reflects the most desirable use of resources 8. Develop activity and project plans consistent with resource use chosen.

122 ECONOMICS OF RECREATION AND PLANNING Massachusetts Bay Colony passed the Great Pond Act in 1641 Massachusetts Bay Colony passed the Great Pond Act in 1641 Required that everybody of water 10 acres or more be kept open to public for fishing and hunting Required that everybody of water 10 acres or more be kept open to public for fishing and hunting Central Park in New York established in 1850s Central Park in New York established in 1850s Late 1800s saw creation of: Yosemite Valley, Yellowstone, Mackinac Island, Niagara Falls Late 1800s saw creation of: Yosemite Valley, Yellowstone, Mackinac Island, Niagara Falls Much of this through efforts of Teddy Roosevelt Much of this through efforts of Teddy Roosevelt Recreational planning still deals with 2 basic elements: man and land Recreational planning still deals with 2 basic elements: man and land

123 TODAY PLANNERS HAVE 3 IMPORTANT TOOLS: 1. Greater public awareness and support – no longer ignored 2. Adequate legislation 3. Ready availability of public monies - ?

124 SITE DEVELOPMENT CRITERIA PROCESS: PROCESS: 1. Identify and categorize the capability of recreational use 2. Identification of recreational uses possible 3. Recreational activities/facilities are chosen based upon: 1. Appropriateness to site 2. Current demand

125 SITE DEVELOPMENT CRITERIA 4. Sutegrate capability/suitability with recreational activity and facilities 5. Select site assessment indicators (unique natural characteristics of site) 6. Related site assessment indicators to Recreational Appropriateness Index

126 THREE USE CATEGORIES: 1. Preservation (limited use) – areas unique and fragile 2. Passive Recreation (moderate use) – areas more numerous and capable of withstanding more human intervention 3. Active Recreation (intensive use) – areas resilient to intensive use by large groups for short periods/generally quite accessible

127 3 CATEGORIES OF LOCATIONAL SUITABLE ACTIVITIES 1. WATER BASED 2. WATER ENHANCED 3. NON-WATER RELATED

128 PLANNING SHOULD INCLUDE: 1. Development of a resource base inventory 2. Determine suitability of 3 management objectives 3. Identify conflicts where overlapping occurs 4. Develop balanced management program

129 ECONOMICS OF RECREATION 1. Those activates which cost neither participant or others anything other than energy and imagination 2. Those conceived and undertaken for the purpose of making money 3. Public recreation which costs money – generally seen as responsibility of the government

130 RECREATIONFACILITY ARE APLIT INTO 3 ELEMENTS: 1. Cost of land – purchase and or removal form tax base 2. Cost of capital improvements 3. Cost of maintenance and operation
