PREFACE The Open Space and Conservation Elements of the General Plan coordinate and guide decisions related to the predominantly un- developed land and water surfaces which influence and shape the formal quality of Carlsbad's physical environment. The Open Space Element serves as an official policy statement for the identification, preservation, conservation and acquisition of open space in the City. The Conservation Element' is addressed to resource management -- the planned management of a natural resource to prevent exploitation, destruction or neglect. The contents of the Open Space and Conservation Elements meet the requirements of State law and provide the City of Carlsbad with a comprehensive document dealing with open space and con- servation resource management. The structure of the elements includes: b Background -- Includes State requirements pertaining to open space and conservation and describes the intent and character of the open space and conservation plan for the City of Carlsbad. Goals and Policies -- A concise statement of the Open Space and Conservation Goals and Policies of the City of Carl sbad. Objectives and Guidelines -- A detailed breakdown of the Open Space and Conservation Objectives and Guide- lines of the City of Carlsbad. c Plan and Implementation -- Identification of prime open space and conservation resources in the City of Carlsbad and the plan and procedures to conserve, develop and utilize those resources. ' Essential Considerations - Examines the status of. open . space and conservation resources in the City, discusses potential obstacles to the preservation of these re- sources, and presents five-relevant open space design concepts that will guide the planning and development of the City. Also includes list of available: funding sources. Appendix - Definitions and list of references. c i 0 0 INTRODUCTION A. STATE LAW -- OPEN SPACE ELEMENT 1 Under state law , cities and counties must adopt an open space plan for 'I.. .the comprehensive and long-range preservation and conservation of ope-n-space land within its jurisdiction.'' "Open Space. land" is defined as ". . . any parcel -or area of land or water which is essentially unimproved and devoted to an open-space use as defined in this section and'which is . designated on a local, regional or state open-space plan as the following: any of 1. 2. 3. 4. Open space for the preservation of natural resources, including, but not limited to, areas required. for the preservation of plant and animal life, including habi- tat for fish and wildlife species; areas r'equired for ecologic and other scientific study purposes; rivers, streams, bays and estuaries; and coastal beaches, lake- shores, banks of rivers and streams, and watershed lands. Open space used for the managed production of resources, including but not limited to, forest lands, rangeland, agricultural lands, and areas of economic importance for the production of food or fiber; areas required for recharge of ground water basins; bays, estuaries, marshes, rivers and streams which are important for the management of commercial fisheries; and areas containing major mineral deposits, including those in. short supply. Open space for outdoor recreation, including but not limited to, areas. of outstanding scenic, historic and cultural value; areas particularly suited for park and recreation purposes, including access to lakeshores, beaches, and rivers and streams, and areas which serve as links between major recreation and open-space reservations, including utility ease- ments, banks of rivers and streams, trails, and scenic highway corridors. Open space for public health and safety, including but not limited to, areas which require special management or regulation because of hazardous or special conditions such as earthquake fault zones, unstable soil areas, flood plains, watersheds, areas presenting high fire risks, areas required for the protection of water quality and water reservoirs and areas required for the protection and enhancement of air quality." 1 Section 65560 et seq., California Government Code - 1 The intent of the legislation is clear - cities.and counties are required to prepare, plans for the preservation of existing unini- proved lands within their jurisdictions that are devoted to the uses or functions listed under the four open space categories. . Such plans should consider more than zoning to preserve open space. They should consider the full range of governmental actions that can affect deve1opment;such as public acquisition, the provision of utilities and services, annexation policies,' the construction' of highways and other capital improvements, use of the Williamson Act, subdivision regulations, and building codes and the relation- ship between open space and housing for all segments of the popula- ti on. 2 B. STATE LAW - CONSERVATION ELEME~IT Under State law1, cities and 'counties must adopt a conservation plan. In order (1) to*enhance the relationship between resi- dents and their surroundings, and (2) to guarantee the viability of the natural and human ecosystems, the Conservation Element must acknowledge and plan for the physical resources, the cultural resources; and the natural processes within or around the jurisdiction. The following resource categories must be included: ' 1. Water 2. Forests 3. Soils 4. ,Rivers and Other Waters 5. Harbors 6. Fisheries 7. Wild1 ife 8. Vinerals 9. Other Natural Resources Section 65302 (d) et. seq., California Government Code 3 . C. STATE LAW - OPEN SPACE ZONING The City is ,required by State law1 to develop open space zoning ordinances to implement the Open Space Element of the General Plan. The ordinances discussed in this docu- ment are not intended to prevent or designate land uses but are designed to regulate the manipulation of the environment to insure that all land development (whethe’r bt be residential, commercial industrial recreational or agricult.ura1) will be more responsive to local physical and biological land resources and canstraints. Section 65910, California Government Code D. INTENT AND CHARACTER OF THE ELEMENTS There is considerable overlap in the components of the Open Space and Conservation. Elements as mandated by State law. The integration of these elements in this General Plan is a response to the inherent complexity of nature and environ- mental planning. It is clear that the legislative mandates for the identification, preservation, and utilization of defined open space and conservation resources-cannot be in- terpreted singly or carried out independently of.one another. As a result, the coordination and synthesis of the two . elements was undertaken to assure an integrated framework for the investigation and planning of these resources. It is the intent of the Open Space and Conservation Elements to: 1. Ensure recognition of the social, economic and aesthetic benefits which accrue from the preser- 'vation of open space within an urban environment. 2. Ensure recognition of the benefits which accrue from the conservation,.development and utilization of natural resources. The Open Space and Conservation Elements are not intended, and shall not be construed, as authorizing the City to exercise its power to adopt, amend or repeal an open space or conserva- tion zoning ordinance in a manner which will take or damage private property for public use without payment of just compensation therefor. This plan is not intended to increase or decrease the rights of any owner of property under the Constitution of the State of California or of the United States. Land to be preserved and regulated for open space and conserva- tion purposes, and areas where it is salient to regulate the possible negative impact of development, are presented as follows: 1. Objectfves and guidelines are established for land and natural features to be reserved within communities and for regulations necessary to control possible negative impact of development on the environment. (See 'Chapter 111) 2. Certain existing open land, natural resources and environmental features are identified as integral and necessary components of the Open Space and Conservation Elements, and standards and criteria are presented governing their use. (See Chapter IV) 5 . 3; The general locations of "Prime" open space and conservation land, representing a framework for an open space and conservation system; are identi- fied on the map titled "Prime Open Space and Conservation Areas". This land contains outstanding recreation, ecological, natural, and scenic re- sources, as well as hazardous areas which should not be developed or should be carefully engineered for public health and safety at the time of develop- ment. (See Chapter IV) It should be re-emphasized that not all land and water features identified as components of these elements are to remain completely devoid of development. However, development that occurs on this land must be consistent with good development practices, and must be regulated to conserve and protect certain physical features and environmental resources in .a manner consis- tent with the open space and conservation policies of the City. c 6 a 11. GOALS AND POLICIES A. GOALS 'It is the goal of the City qf Carlsbad: 1. To coordinate open space uses with other land uses for mutual enhancement and creation of a "human" urban environment, which includes development and expansion of recreational land, conservation of natural and man-made amenities, and preservation of options with regard to agricultural land. 2. To preserve optimum sustainable environmental quality levels with respect to air, water, sound levels, and plant and animal life. 3. .To prevent incompatible development of areas that should be preserved or regulated for scenic, historic, conservation. or pub1 ic health and safety purposes. 4. To preserve and create an open space system of panoramic vistas, and other aesthetic resources) that will maintain community identity, achieve a sense of natural spaciousness, and provide visual relief in the cityscape. . aesthetic value (such as flower fields, groves, 5. To preserve an adequate amount and variety of open . space for outdoor recreation which shall include, but not be limited to, partks, beaches, areas for organized sports, conhecting corridors with trails, water recreation areas (beaches ,. lagoons, iakes) unique conservation areas for nature study, and semi-developed areas for camping. 6. To protect select wildlife through the preservation of feeding, nesting, and breeding areas. 7. To conserve and encourage the use of all forms of vegetation needed to (a) prevent 'erosion, siltation and flooding, (b) protect air and water resources, and (c) protect and enhance visual resources. B. POL IC1 ES It 1. 2. 3. 4. 5; 6. 7. 8. is the express policy of the City of Carlsbad: Agricultural Lands: To regard agricultural land and prime soil as a natural resource and economic . asset, and as a signifiqant contrasting land use to the urbanized environment of the City. Development Areas: To encourage the provision of malls, plazas, green areas, etc. fn structures and the preservation and provision of parks. Greenbelts: To establ ish greenbelts to preserve and/or create open space areas as a means of maintaining community scale and identity, separating conflicting land uses, and achieving a sense of natural openness as an integral part of urban surroundings. Implementation: To provide an organizational structure to systematically develop and implement comprehensive plans for open space and conservation. Landforms: To protect the unique variety of landforms distinctive of the City's topography and to ensure that the development process considers and strives to preserve these landforms rather than to create an unnatural, uniform landscape. Outdoor Recreation: -To conserve, develop, and uti1 ize areas particularly suited for outdoor recreation by preserving areas of unique scenic, historical and cultural value and developing areas especially suited for park and recreational. purposes. Preservation of Natural Resources: To preserve natural resources by: protecting fish, wildlife, and vegetation habitats; retaining the natural character of waterways, shoreline features, hill- sides, and scenic areas; safeguarding areas for scientific and educational research; respecting the limitations of our air and wdter resources to absorb pollution; encouraging legislation that will assist in preserving these resources. Public Health and Safety: To protect public health and safety by preserving natural and man-made hazard areas as open space and-taking special precautionary measures to protect the public safety where develop- ment is possible and permitted. 8 9, Taxation: To encourage the development of open space and conservation systems by assuring that property taxes are consistent with the use of the land. 10. Water: To assure that gn adequate supply of water of acceptable quality is available to meet the needs of present and future residents by supporting State and local activities to develop conventional water sources, to research new water technologies and to conserve water resources through sound water management programs. 9 0 111. OBJECTIVES AND GUIDELINES In general, the designation of open spacemd the determination of conservation practices are dependent on an area's natural features, the location of urban development, open space and conservation which citizens desire and are willing to achieve. The following objectives and guidelines are consistent with the previously stated goals and policies. It should be emphasized that a change in the goals and policies of the City of Carlsbad will necessitate a corresponding change in the objectives and guidelines. c goals, some recreation demand data, and' the type of environment 10 A. Floodplain and Water Resource Maragement ObjectPre: within the City of Carlsbad, including, but To conserve, develop and utilize the water resources -- floodplains ? shoreline lagoons, waterways , reservoirs; not ‘limited to, lakes, ponds, and Guidelines : 1. 2. 3- &. 5. 6. 7. 8. 9.

Alterations of waterways that cause significant adverse impacts on the environment will be prohibited. and lhere feasible, future developments will integrate natural waterways with other open space systems of the City with a view of maximizing the benefits of them to all citizens. Industrial waste , agricultural runoff, water softener dis-. charges, domestic detergents, and other forms of water pollution shall be controlled 51 the sanitation sewer system, the storm drain system, and other methods of control as defined in State, Federal, and County laws. New developments shall be subject to the review and recom- mendations of the staff of the Calsornia Regional Mater Quality Control Board. The construction of improvements to coastal lands which will require protection from coastal erosion in the foreseeable future be discouraged. Setbacks from the coastal bluff face and beach sands and public access points shall be established to protect the public interest in the shoreline as .a unique recreational and scenic resource. L Construction in, and adjacent to, coastal waters rill be evaluated relative to its effect on recreational uses. The interim policies of the California Coastal Zone Conserva- tion Coinnisaion and resuitat land use plar~ will be recoz- nized and utilized when evaluating developmsnt in.the coastal area. 11 . B. Hillside and Soil Resource Management Objective: To preserve the identity' of those areas of the City with unique topographic features and to estab- lish'proper soil management techniques to eliminate or minimize adverse and unsafe soil conditions. Guidelines: . 1. Grading for building pads and roadways will be accomplished to maintain the appearance of natural hi 7 1 sides. 2. Plans for erosion and sediment control measures including landscaping and provisions for main- tenance responsibilities will be a requirement of the approval processes. 3. ,Where known or suspected hazardous geological or soil conditions exist, the developer will be required to: ' . a. Conduct detailed studies of the area by qualified experts in advance of development planning. b. Submit these findings along with measures-on . how to protect against hazardous conditions. 4. Proper distances will be maintained by all new development from identified or suspected hazardous . conditions. 5. Density and intensity of development on hillsides will relate t.0 the slope of the land in order to preserve the integrity of the hillside. 12 . C.

DESCRIPTION AND INTENT OF PLAN: ‘This section, including textual content and graphic presentations, and subsequect, mandated open space zoning requirements, constitute the Open. Space and Conservation Resource Management Plan for the City of Carlsbad. The intent of the Plan is to accomplish the goals, policies and objectives of the elements in an equitable manner. The Plan is structured to identify the resource areas and establish developmental standards. By the adoption of this Plan, the City of Carlsbad declares that the proper management of the City’s en- vironmental resources requires standards and criteria for the protection, maintenance, and enhancement of valuable natural, economic and cultural resources. 16 c 1. Components of the Plan: The following lands are integral and necessary components of the Open Space and Conservation Resource Management Plan: a. Reserved Land Elithi; the City: (1) Publicly-Owned Open Space: Used for recrea- tional , educational , institutional , conser- vation, and protective purposes including parks, beaches, 'lagoons, trails, access ways, golf courses, school playgrounds, reservoirs, cemeteries, sanctuaries, botanical areas, flood control channels, airport clear zones, disposal sites. (2) Privately-owned open. space committed to and us-ed for recreational, educational, conser- vation, and protective purposes including parks, playgrounds, beaches, beach access ways, greenbelts, cemeteries , 1 agoons , and nature areas. b. Semi-Reserved and Restricted Land: (I) Held privately or publicly on less permanent basis for recreational, agricultural, or transportation purposes including go1.l courses, agricultural preserves, airports and clear zones, railroad rights-of-way, highway and street rights-of-way, utility ' easements, and beach access. (2) Planned publicly or privately for recrea- tional or other open space purposes including areas as designated in the general plan of the City. c. Unreserved land whose undeveloped state or open space function is susceptible to development including: (1) Scenic areas. (2) Sensitive landforms such as ocean and lagoon bluffs, beach sands, excessive slopes, land- slide areas, major peaks and ridges, and flood plains. habitats,bird refuges, marshes, mudflats, riparian habitats, and areas of unique vegetation. (3) Sensitive ecological areas such as wildlife (4) Natural resource lands such as crop and grazing lands, Class I and I1 soils, sand and gravel dqposi ts , and watersheds. e (5) Historical and archaeological sites. (6) Areas buffering and structuring cities and communities. 2. Order of Importance of Open Space and Conservation Resources: The order of importance for the protection, main- tenance, and enhancement of open space and conserva- tion resources is as follows: 1st Areas which would be maintained as open space in order to provide for public health and safety including floodplains, geologic hazards and water resources. . 2nd Areas which would protect and enhance hill- side and soil resources, wildlife habitats and unique vegetation. 3rd Areas most suited for agr'icultural production. 4th Areas having unique and special resources in- cluding, but not limited to, visual amenities, recreational uses, landmarks, areas which provide buffers between incompatible land uses, and areas which provide linkages to larger open space areas and give form and identity to the City. e L B.- Prime Open Space and Conservation Areas: The map titled "Prime Open Space and Conservation Areas" designates those high priority resources (as. described in this section) that are combined to create a logical and comprehensive open space system. It should be recognized that there are many minor open space areas in the City which collectively serve to provide additional significant open space to the citizens, even though they are not individually large enough to be mapped or described. The areas shown on the map include,but are not limited to, the following: 1. 2. 3. 4. '5 . 6. 7. 8. 9. 10. Existing school and park sites. Proposed Regional Parks and ot'her major recrea- tional areas including golf courses. All marine waters, tidal flats, lagoons, marshes and estuaries. Floodplains and major waterways. All land and bodies of water necessary for the preservation of wildlife habitats and unique and desirable vegetation.. Significant grove areas. Airport flight approach and take-off zones. Water reservoir sites.. Utility corridors. Existing "Planned Community" zones. C When development is proposed to take place which may have an effect on these areas, special regulations will have to be utilized to assure that t.he intent of the Plan is being carried out whenever possible. It is to be understood that the standards, criteria and ordinances established by this Plan would be utilized in conjunction with the standards and regulations of the City's zoning code, subdivision code, and any other related ordinances, resolutions or policies. In the case of any land for which contradictory standards or regulations exist, the more restrictive standard or regulation shall apply. . 20 No permit shall be granted by the City for the use, development or alteration of land identified on the map titled "Prime Open Space and Conservation Areas'' until the grantee presents evidence of compliance with the standards and regulations of the Open Spa'ce and Conservation Resource Management Plan. The following standards shall apply'to any use, development or alteration of land shown on the map, provided however that such standards shall not apply to the development of less than one single family dwelling unit on a parcel of record at the date of the adoption of Open Space and Conservation Elements of the Carlsbad General Plan. 1. For any use, development or alteration of a parcel land coverage shall not exceed twenty (20) percent of the total parcel area.' 2. For any use, development or alteration of a. parcel at least sixty (60) percent of the total parcel area shall be maintained in a manner which protects and conserves the natural resource potential of the parcel. 3. The building height and setback standards specified by the underlying zoning may increase or decrease is necessary for the compliance of a proposed use, development or alteration with the purpose and intent of this Section. 4. For any residenti.al use, development or altera- tion of a parcel included in this zone, the following building types are permitted: single family detached dwelling units, duplexes and multiple-family dwelling units; provided however that maximum number of dwelling units shall not exceed the maximum number of dwelling units that wou1.d be permitted pursuant to the standards of the base zone in which the use development or alteration is located. However, dwelling unit density and intensity of development indicated therein may be further reduced if dictated by the following land carrying capability considera- tions: topography (slope) geology (slide, soils) access (availability of road access) public facilities and services (availability) ground cover of proposed improvements scenic values ecological values 21 5. 6. 7. 8. '9. Commercial and industrial development, public facilities, and .other uses permitted in open space areas, nct generally considered open space uses, shall only be approved after full .evaluation of the above listed land carrying capa bi 14 ty cons i dera t i ons . Commercial uses permitted in open space areas shall only be of a convenience nature relating to various open space uses and strictly controlled as to design and location. ' -- Signs in open space areas shall be limited to those essential to safety, public convenience, and identificatjon of structures, historical sites, campsites, etc. Beach and ocean areas within the jurfsdiction of the City shall be considered as open space. No use, development or alteration of land in- cluded in this zone shall have a significant adverse env'ironmental impact upon major wild- life, vegetation or marine resources. 22 . ..! L, 0 C. Resource Management Districts:. - The section titled "Prime Open Space and Conservation Areas" identifies a comprehensive open space and con- servation system for the entire City and establishes standards for its enhancement and protection. This section specifically describes those key resources that are either included in or would further complement that system. These resources include: . Hillside and Soil Resources . Agricultural Resources ' . Unique and Special Resources . Floodplain and Water Resources -- The following sub-sections 'consist of criteria to be used to determine what areas are included within each resource district and a combination of use restrictions and develop- delineate each of the districts are also included. ' ment standards appropriate to each. Maps that generally Property identified in more than one district is subject to the standards app1ica.ble to each. An example of this overlay approach is illustrated in Diagram 1 using three districts -- a floodplain, a hillside, and a wildlife habitat (a unique and special resource). A development located at point ''A" would have to comply with the standards applicable to flood plains. Proposed develop- ment at point "B" would have to comply with standards ap- plicable to unique and special resource lands, and hillsides. At point *tC", only the standards applicable to the preser- vation and conservation of hillside areas would have to be met. The major drawback to individual overlays for each type of "Resource Management" land is that the ordinance may be difficult to administer if many diverse types of open space and conservation resources and constraints are found within the same area of Carlsbad. Determina- tion of the standards that apply to any given parcel will require a review of all the overlays to see if the parcel is located within one or more of them. The standards appropriate to each applicable overlay will then have to be collated. Some of the standards applicable to one type of open space will be applicable to others so there may be some redundancy. 2h F DIAGRAM 1 . 25 0 0 1. Floodplain and Water Res.orJrcc.es a. Floodplains: Floodplains are those land areas in and adjacent to a watercourse which is subject to inundation during a “700 year flood”. Floodplains include a floodway which is defined as that portion of the floodplain that is reasonably required for the passage of flood waters of a given magnitude. The precise locations of these areas shall be as determined by the U.S. Army Corps’of Eng’ineers or the San Diego County Department of Sanitation and Flood Control, or the City Engineer. The following standards of development are established to protect life, minimize public risk, and prevent or reduce potential flood damage of property: 1) Uses within a floodway shall be limited to those which would not hinder the free flow of flood waters and would maintain as natural of-an appearance as possible. 2) Uses within a floodplain shall be limited to those permitted uses of the underlying zoning district and shall be designed in such a way as to minimize possible flood damage. 3) Any development within a floodplain shall. comply with all applicable Federal, State and local requirements. 26 b. Coastal Area and Lagoons: The City of Carlsbad declares that the coastline and lagoons within its boundaries are distin'ct and valuable natural and scenic resources.' The following. standards of development are .estab1 ished to preserve and protect those resources and shall apply to all coastal and fagoon water areas and to all land adjacent to and within one hundred (100) feet of the established vegetation line or other defining element of the high water line of said waters or from the exists: . crest line of an adjoining bluff or cliff .if one Prior to the issuance of any permits for develop- ment within this district, it shall be demon- strated that the development is consistent with the goals, policies and objectives established in the Open Space and Conservation Elements. Land coverage shall Rot exceed twenty-five (25) percent of the total parcel area. The building height and setback standards specified by the base zoning district may increase or decrease if such increase or decrease is necessary for the compliance of a proposed use, development or alt.eration with the purpose and intent of these standards. For any residential use, development or alteration of a parcel included in this district the following building types are permitted: single family detached dwelling units, duplexes, and multiple- family dwelling units; provided, however, that the maximum number of dwelling units permitted' would be established by the base zoning district in which the use, development or alteration is to be located.

Recreational Lands: The. Parks and Recreation Element of the General Plan delineates all lands presently secured far recreation and all lands proposed to be secured in order to establish a comprehensive parks and recreation plan for the City. General standards which are applicable to this section include: 1) Where the map titled "Prime Open Space and Con servation Areas" indicates greenbelts, water courses, and linkages, an easement not less than one hundred (100) feet in width shall be pro- vided for public recreation and access. If the gross area of such an easement exceeds ten (10) percent of the total parcel size, the City shall compensate the owner. facilities or open space available for their employees. 3) Creeks, utility easements, and other open areas shall be utilized as part of an overall master plan for parks and recreation facilities. 2) Major places of employment shall have recreational 4) Open space lands held by the public for recrea- tional use shall be accessible and should be provided with essential utilities, public facilities and services. c.

The following areas shall be identified and preserved as open space wherever possible: 1 ) Hi 11 s i'des , hi 1 1 tops, Val 1 eys , . beaches , 1 agoons and lakes that provide visual and p-hysical relief to the Cityscape inthe form of natural contrast to the built-up, man-made scene; 2) Open Space areas which define neighborhood, district and City identity; 3) Unique topographical features or natural rock outcroppings and other notable landmarks; 4) Areas of significant historical value; ' 5) Prime vista s'ites; 6) Scenic and historical corridors (refer to the Scenic- Highways Element of the General Plan). 47 . 0 D. - Design Principles: As reflected in the map titled "Prime Open Space and Conservation Areas", the application of Open Space design concepts have resulted in - the following: The establishment of recreation cores both at a City'- wide, community and neighb'orhood scale composed of local ana regional parks, beaches and .lagoon oriented. recreation opportunities. , b. The preservation of natural features, natural resources and processes resulting in open space and conservation nodes, and a pattern of linked conservation, recreation and scenic corridors as a framework or containers within which more inten- sive development would be more appr0priat.e to occur [design with nature). C* The development of an open spac'e framework; built by joining major public, quasi-public, and private open spaces into a continuous system, promising . increased economy and efficiency through combined use, and increased amenity in the form of linear open areas. The use of flood plains, utility easements, abandoned railroad rights-of-way, and scenic highway corridors as linear recreation and scenic amenity corridors infused within the urban fabric. e,' The regulation of the impact of development on physical features, natural resources, natural processes and hazardous areas in a manner consistent with good development and conservation practices.

The open space system should be pervaded by the general concept of "openness"; open to choice, open to active use and manipulation, open to view and understanding, open of access, open to new percep- tions and cspcriences. bo Thc open space system should intimately connect with the total environmcntal and the city's daily liie-- not a specialized antithesis to the city, but a tlit con~cst of thc wI101c, uses and circulation, the rcgiorlal sctting, the constellations of living systems. 49 ' functional part of it. It should bc designed in tho pattcr11 (ii otlicr city c C. The open s'pace system should be a complete design, even if a large-scale and abstract one. A'set of drawings and text should show the pattern of use, form, and charac-ter of all the open spaces as a com- plete'subsystemm, in relation to the same pattern of the city as a whole. All open spaces and their uses and form should be taken into account, not just the publicly owne-d ones specifically designed for recrea- tion. The design should show the pattern -03 major views and the distribution and use of vacant .lots. It should necessarily be based on a comprehensive 'visual analysis of the city, as well as other kinds of surveys. d, It is fundamental that the open spaces themselves are meaningless except in relation to th.eir use and to the characteristics and aspirations of their users. The design of more detailed plans for ea.ch open space area should show who would use these open spaces and .how these uses relate to present or future desires. Along with the desigh for the form of the spaces would be a program fo,r use,.training and administration. . e. The design of the individual open spaces should empha- size variety and avoid reliance on park stereotypes. The spread of user requirements .and technical possibili- ties should evoke an equally wide spread of kinds of open space in Carlsbad. Allied to this is an emphasis on access and approach, the meeting edge, contrast, immediacy, and close coupling. . f. The city should ensure that roads and other transporta- - tion systems through and adjacent to open spaces be compatible with the special nature of the open space lands. These roads should be individually designed to emphasize scenic values and conform to the unique setting of the areas traversed. Freeways, major highways and other transportation and public rights- of-way are somwtimes determinants of urban form. may serve, in soqe instances, to link elements of-the. open space system. Future design, location and improve- ment of these facilities should recognize these concepts. t They . g. There is need for design for movement. for enjoyment in itself, an ability to communicate the meaning of large environments, an obvious relation to access and to The fundamental nature of the city. This calls for lincar open spaces, specialized routes, and general organizing networks. L It has a potential .. . 50 E. Implementation Development of a viable Open Space and Conservation Resource Management Plan requires a concurrent implementation pro- gram. Such a program must identify public and private areas of cooperation and the tools needed to develop the Plan. As such, this implementation program discusses existing sources of funds for open space land, methods of preserving 0pe.n space, existing land use controls and a program for the implementation of the Plan. The preservation of open space often requires interference with the individual property rights of the private land owner. It should also be understood that the Plan cannot be implemented withoat some cost to the city, even if only the cost of administration. However, as this section indi- cates, the City need not buy a fee simple interest in every acre of land it wishes to preserve as open space. There are other methods available that ac:complish the same purpose. t 1. Available Techniques A variety of techniques are available for the acquisi- tion or management of open space.iand conservation . areas, both at the regional and the local scale. These methods generally fall into.one of the following categories: a. Acquisition of Fee Purchase a) purchase with life estate b) lease purchase excess condemnation (or purchase) purchase and leaseback e) option of purchase f) deferred purchase Gift a) in .fee b) with life estate Trade or transfer of public land Tax foreclosure Street vacation Urban redevelopment process Dedication (Quimby Act) Eminent domain b. Acquisition of less than fee (by purchase, dedication or gift) Open space/conservation easem-ents Development rights and/or easements Public easements to beaches,.recreation areas, etc. Slope conservation easements Scenic easements (for highways, park entrances, historic sites and/or areas) Public purchase and resale with certain restrictions Compensable regulations (should be combined with zoning Open Space Maintenance District c. Zoning Actions (police pohier) 1) Flood plain. zoning 2) Ocean - submerged land zoning 3) Zoning to preserve scenic amenity- (height limits, sign control, architectural control, etc.) 4) Exclusive agricultural toning 5) Open Space zoning - parks, open spaces, stream valleys, flood plains, watershed protection areas, cemeteries , go1 f courses and country .cl ubs, where shown as open space on the general plan. Other lands should be considered under type of zone to restrict development, hillside areas, wetlands, slide areas and earthquake zones. 6) Zoning for large lots (Estate Zoning) 7) Planned unit developments. (P-C, P-M, etc.) with open space requirements (cluster development). d. Other restrictions on development 1) Possible control over developments by the Federal Housing Agency (FHA) 2) Private restrictive covenants 3) Designation of Open Space Plan as "open space" 4) Denial of public facilities 5) Requirements for Environmental Impact Statements, 6) Subdivision Regulations and requirements of A.B. 1454 and A.B. 1301 L e. Transferable Densities 1) Provides for density transfers or reallocations to private landowners in order to secure and/or preserve open space and conservation areas. 2) Establishes procedures to allow a property owner to transfer by sale, with the approval of the City, his land's development density to another property in the same section of the City. 3) Requires the property owner incurring a reduction in the development potential of his property to dedicate the development rights to the City. f. Tax Incentives- 1) By contract 2) The California Land Conservation Act of 1968 (Williamson Act) allows valuation of farms at .present use value. 3) California constitutional amendment' providing tax exemptions for non-profit golf clubs (valu- ation for recreational use). In ,order to qualify for such exemptions, golf courses must be 10+ acres and non-profit. 4) Reduced tax assessment when the public has acquired development rights or other easements. c 5.G :E FUNCTIONS TECliN IQUES ACQUfSlflOail OF FEE FJHC~I~SL: OUTRIGHT PURCCBASE ANA;, CE ACOUIS I'YIOd PLRCIIASL.

Criteria for Determining Technique c Basically, the levels of land use control for open space and conservation purposes presently in use in California 'range from purchase of the full fee, which is total exercise of control; through acquisition of less than the fee, to zoning, which is the least permanent method of control as presently exercised, Tax benefit methods of exerting influence are little used, though desirable, and when used, are used in combination with zoning or less than fee acquisition. The major tax incentive device utilized in Southern California is the Land Conservation Act (Williamson Act). The following are criteria that may service as guidelines in judging the level of control necessary for the preservation of various open space and conservation components. a, b 9. c .. Acquisition of Fee This method. of control is recommended when the desirable open space iFreas are in danger of development for other than open space use and: 1,) 2.) the areas are intended for full public use such as public recreation areas or watershed areas, or preservation of the open space use would preclude any private use -whatsoever. NOTE: If the less than fee rights are in the neigh- borhood of 75% of the full fee it may be de- sirable as a matter .of policy to acquire the full fee. This judgment is made in some cases such as in State Department of Water Resources acquisitions. Acquisition of Less than Fee This method is recommended when the desirable open space areas are in danger of development for other than open space use and securing of "less than fee rights" such as scenic easements, conservation easements, and development rights will leave substantial and valuable rights with the property owner. grazing, dairying, private recreation, very low density housing, limited mineral development, etc. These rights may be for farming, Zoning and Development Controls This method is' recommended when the character of the . desi-.:able open space areas can be permznently- preserved in private oxnershi? under zcning 2112 development coatrols. 1 Zoning for public safety Under this classification would be those areas con- sidered unsafe to build on because of flood hazard, land subsidence, steepness of shape, fire, slide or earthquake hazard, or airport approach zone hazard. 2 ) Zoning for conservation or scenic amenit.y Under this classification would come agricultural preserves, exclusive agricultural districts, areas for mineral extraction, scenic conservation districts, open space zones, special treatment, or design control zones and estate size property zones. and a.. b. C. d. e. f. g* 3. Action Program The following is a series of actions that.should be undertaken by the City in order to keep .the Open Space. Conservation Elements current and re1 euhnt: Provide a vital link between the adoption of the Open Space and Conservation Elements and the im- plementation of these elements. Continue to develop and refine specific, short-range plans and implementation programs, including the proposals presented in the Open Space and Conservation Eaements . Assist single purpose agencies to plan for and acquire when needed, and in advance of need in some cases, those areas that will be required for their specific open space and conservation purposes (financing, coordination, and land bank functions). Continue the tasks in process to develop and refine statements of goals, operational objectives, and the divisions of responsibility required among the several levels of government and the private sector which are required as a basis for achieving ef- fective intergovernmental management of open space and conservation resources. Develop additional devices and procedures for insuring the fullest degree of coordination and communication with all affected public agencies as a basis for their support of the City's plans and their imple- mentation provisions, where relevant to their area - of juri sd i cti on. t Conduct more detailed analysis of the natural environ- mental factors of geology, hydrology, soils, plant and animal ecology, elimate, and resources which are fundamental to the planning of a viable and effective open space and conservation system. Continue to identify the location and significa.nce of hazardous, unstable seismic or other areas in which urban development should not occur, as well as areas of exceptional, unique or fragile character which should be conserved as areas of positive open space value. Develop more detailed demand estfmates, space standards, and service area criteria for all forms of open space, conservation, scenic highways and recreation in the City, and evaluate the attitudes and desires of recreation consum5rs. Identify the varying human needs for different types of recreation facilit-ies and services in the City and respond to the special needs of the aged, the young and others whose mobility and ranges of choice are limited geographically, physically or economically. h. c i. j. k. .* . 1. Compare the full range of demands for various types of open space, conservation, scenic highways and recreation lands. with the inventory of aatural and man-made resources of the City. and locations which are physically suitable' and efficiently located. )latch the activities and facilities to specific sites Develop quantified data on the respective economic and social costs and benefits of alternative open space - urban development plan options ad specific sites. Develop a procedure which the City c2n operate on an on-going basis to mollitor the economic effects of actual change produced by public and private sector development actions, as a means of improving the adequacy of the preservation plans and programs to meet their objectives. Supervise the preparation of prototype site plans and design studies to illustrate recomended developmental approaches for various open space, conservation, scenic highway and recreation lands ., Provide landowners and interested citizens with information on estate, income, and property tax consequences of various forms of gifts; and have available for disccssion with pro- spective donors, legal forms for the conveyance of various types of interest, such as the fee, the fee subject to a life estate, scenic easements, flooding easement, and fee subject to reversion if the goverment ceases to use the land for open space purposes.. Continue to prepare and refine a long-range plan for a de- tailed City-wide system of open space, conservation, scenic highways and recreation lands on the basis of the evalua- tions and tasks described above, to optimize the benefits of the City's unique setting and environment. This will consist of a map of the entire City, on which will be in- dicated all existing or proposed open space, conservation, scenic highways, and recreation lands. 12 will also con- sist of i? plan text describing each of these lands or locations in terms of the approximate size of the sites, the purposes or fitlnctions thcy are-intended to serve, their current status of development and ownership, their estimated cost, and the means recomended to implement their inclusion with the open spzce, conservation, scenic highways and recreation lands system. The plan nap and text will constitute a combination of the Open Space, Con- servation, Scenic: Highways ElerrLents and certain aspects of the Recreation Element of the City's General Plan, and will provide the basis for preparing required environmental im- pact reports. m. Initiate, coordinate, and supervise specific implementation programs for both short-range 2nd long-rage plans, in- cluding among other items a capital improvement program, a financial plan, proposed changes to the City's development regulations, and the acquisition of fee and less than fee rights to land. - n. Undertake specific site evaluations with the-intent of securing Open S?ace Easements in accordance with adopted policies and plans. Comission the specific restrictions and/or privileges to be secured. Analyze and report to the Planning 0. Give specia'l consideration to the use of density transfers or reallocations as a means of preserving open space. While cluster or planned community development permits variable density within a single residential district, transferable density zoning permits variation throughout a whole community. It might be initiated by taking the following steps: .The city accomodate an optimum future population. Then it would create a fixed number of "density units," each of which permits con- struction at a given level of density. These density units would then be allocated to the property owners according to the size and presently permitted use of their holdings. density units would be freely transferable: bought and sold. high-density subdivision, he would have to buy enough density units from property owners to-achieve the desired density for the subdivision. would determine the average density required to The They could be Should a developer wish to construct a Establish procedures to allow a property owner to transfer by sale, and with the approval of the city, the development density to another property owner's parce.1 in the same section of the city, Require the property owner incurring a reduction in the development potential of his property to dedicate the the development rights to the city. Unlike zoning, this action is considered an "enforceable restriction"' under state law and will impact the tax assessment of the grantor's property and hence his property taxes. (TechnicaJ Note: Real property subject to taxation is assessed at the fu1.l value thereof. Full value is defined judicially as the price at which the property would sell under ordinary circumstances.

This chapter presents a summary of certain com- ponents of the open space, conservation and outdoor recreation resources and constraints. , - -. 1, Rapid Transition: Various economic. pressures and . governmental decisions coupled with population growth have over the past few years stimulated the rapid ,. transition of land from rural, agricultural, natural and scenic resources, conservation and recreation uses to urban uses. 2. Urbanization: An' examination of the urbanized areas of Carlsbad demonstrates that past development policies have resulted in a lack of preservation of sufficient open space, and that development has occasionally en- croached upon flood plains, lagoons, steep slopes, . wooded areas and prime agricultural land. topographic areas. of the City, and the terrace about 30%. 70% of the City consists of rolling hills. 3. Topography: Carlsbad can be divided into 3 distinct The beach comprises less than 1% Approximately 0 Beach: The beach is very narrow. Its width Apprbximately a third of the . omar Airport Road, is sea cliffs which range does not exceed 500 feet, and is generally less than 200 feet. . coastal boundary, from Batiquitos Lagoon to Pal- from 40 to 50 feet high. 6-1/2 miles of beach in the City, more than four miles is in public or quasi-public ownership. Of the approximately Q Terrace: The terrace is gently and uniformly inclined to the west. Maximum el-evation ranges from about 40 feet in the west to about 400 feet in the east. The terrace is cut by the channels of four west-draining streams, three of whi.t=h empty into lagoons. e Hills: In the area of rolling hills, elevation ranges from about 100 feet to about 1,000 feet, but 80% of the area is less than 500 feet. Greatest. relief is along the eastern boundary of the City. Here the hills are steepest, with sharp, incised drainage divides. 4. M-ajor Recreation Areas in Carlsbad: No non-beazh regional or community parks exist in Carlsbad. There population of the City. ~ are only five neighborhood parks serving'the entire 5. Coastline: The coastline is a major resource of Carlsbad. The public's access to these coastlines have been impaired, not so much by development, but by the lack of improved access. 6. .Canyons: The canyons have great importance for Carlsbad because they have considerable value to a comprehensive open space system. The present policies of the City do not adequately protect these resources. - 7. Watercourses: Development of Carlsbad's river beds and creeks has had at least two detrimental effects on the environment. First, development in certain areas of Carlsbad has blocked the natural flowing . of water. Second, the soil of the watercourses and banks is quite fertile and development precludes its cultivation. 8. Steep Slopes: Steep slopes are central to the problem of flood control and erosion. This is particularly true in the Carlsbad area where natural vegetation and ground cover is not thick, and the rainfall is concentrated in the winter season in which 90% of the annual precipitation occurs. Also, construction on steep slopes often results in a form of urbaniza- tion that is difficult and costly for the City of Carlsbad to service, besides presenting grave public safety hazards when steep slopes are'unstable. Approximately 10% of the City contains slope lands greater than 26%, and 15% of the City contains slope lands ranging from 16 to 25%. If thes-e slopes are left predominately undeveloped they can give a greater impression of openness than th.eir size alone would indicate--particularly if they are abutted by low-lying areas of urban development. - \ 9. Agricultural Soils: There is no program to preserve prime agricultural soils in Carlsbad at the present time. The Land Conservation Act has riot been used. 10. Hills: Excessive alteration has occurred to utilize hills and hilltops for home sites. 62 . 0 .. 11. Surface Water: Surface water in Car-lsbad is too meager and undependable to be considered an exploitable resource. The Water Resou?ces Division of the U.S. Geological Survey studied the flood potential of the streams in Carlsbad. The areas susceptible to flooding are those underlain by alluvium, the lower reaches of the four main drainage basins, and the lagoons. These' areas are shown on the map titled "Flood Prone Areas ." * Most of the streams are intermittent and drain into the three lagoons: Buena Vista, Agua Hedionda and Batiquitos. Only Agua Hedionda is a tidal lagoon open to the ocean. 3x1 Dkgo Gas and Electric Cppany does period maintensace dredging to assure adequate coolmg - water for the Encina Generating Plant. Batiquitos Lagoon contains brackish water; the degree of salinity varies seasonally with the amount of rain- fall. Buena Vista Lagoon is a freshwater lagoon and is being maintained by the Cities of Oceanside and Carlsbad. The lagoon is owned by the State Department of Fish and Game. The lagoons have been utilized in the past for sewage disposal and the head of Buena Vista Lagoon has been artificially filled. At the present rate of siltation, with debris origi- nating mainly from construction projects in their drainage basins, it will be perhaps ten to twenty years before Uuena Vista Lagoon and Batiquitos Lagoon are filled in,. If these lagoons are to be preserved, a comprehensive program of erosion and siltation con- trol would have to be undertaken. \ W < 12. Groundwater: Data from the California Department of Water Resources indicate that the only sources of groundwater in Carlsbad are the alluvial deposits and the La Jolla Group rocks. About 80% of the groundwater is in the alluvial deposits with the remainder in .. the La Jolla Group. Groundwater is currently being used for rural and agricultural purposes. Chemical analysis performed by the Department of Water Resources show dissolved salts and minerals make the water of questionable quality for domestic use, but it is considered ade- quate for agricultural purposes. c The Department of Water Resources data indicate that there is no area within the Carlsbad City limits where a high yield well could be developed. 13. Flood Prone Lands: Mapped in this document are 100 year flood prone areas with upstream drainage areas exceeding 25 square miles. chance 011 the average that these lands will be inun- Detailed analyses of flood prone lands are contained in the reports prepared by the U.S. Army Corps of Engineers for the Euena Vista and Agua Hedionda Creeks.

Water Resources: In Carlsbad, as well as other coastal communities, where competition for land is intensifying, it is particularly difficult to coordinate land use and water resource/open space/conservation planning.

Vegetation and 1Vildlife Habitats: The majority of vegetation cover in Carlsbad can be divfded into foul' types: (a) Coastal Sage Scrub and Chamise Chaparral, (b) Eucalyptus Groves arid Woodlands, (c) Cultivated, Fallow Fields, Grasslands, and Disturbcd (Rudcral) Areas, and (d) thc Vegctation Associatcd wi th Laigooris. c Four basic types of wildlife habitats existing in Carlsbad: (1) chaparral, (2) woodland, (3) ripar- ian, and (4) coastal lagoon. The chaparral habitat contains vegetation classified on the San niego County Soi 1 Survey miips as "broad-leafed chaparral ," "narrow- leafed chaparral, I' and to some extent, "barren." The riparian habitat includes areas Within these zones of habitats are many interrelated ecosystems, or functional physical and chemical relationships. There are interrelated environments within these habitats "determined not only by geo- graphic location, but by soil type, draina'ge, erosion,. water, wind, and many other environmental features-- considered of a local nature." 16, Climatic Zone: The City 'of Carlsbad's climate is largely controlled by the surface temperature of the Pacific Ocean. This and the distribution of land and water areas are the determining fa'ctors .for the typically mild winters and moderate summers. The average rainfall is 10.4 inches, but the precipita- tion occurrence is highly variable. Temperatures in this area are influenced by the coastal fogs and air currents from the ocean. The annual average minimum temperature is S5.1°F, while the annual aver- . with intermittent drainnvc. .\ * age maximum temperature is 71.4OF.

The three lagoons existing constitute a major resaing point along the Pacific Flyway for ducks, geese, and many water birds. Further, the lagoons contain or have the potential to be rehabilitated to contain fl-ora . and fauna which cannot be found anywhere else in the world. Once blocked or built upon, the lagoons will drastically change [the process has started), causing irrepairable damage to the bird populations of North America.

Since these lagoons differ in respect to such aspects as ownership, physical characteristics, governmental jurisdiction, potential uses, and financial and environmental costs of implementing various proposals, it is essential that each be considered in its own 0 light. Each Buena Vista La,qoo:i: San Diego County's Regional Parks Implementation Study recommends that 3uena Vista Lagoon be developed as a nature preserve oriented regional park. Although the lagoon bottom as it presently exists is owned by organizations interested in such uses, most of the adjoining land intented for park use, namely Hosp Grove, is no longer available for such purposes.

Since most of the south shore of the lagoon is owned by San Diego Gas and Electric Company and the remaining shoreline and adjoining acreage is privately owned, it appears that joint cooperation between San Diego Gas and Electric Company, the City, and private interests is essential if Agua Hedionda Lagoon is to be satisfac- torily developed. tation Study as a major intensive water sports oriented ?

The City of Carlsbad, however, has taken the position that although it endorses the concept of a. regional park at Batiquitos, it favors joint City-County and public- private participation to accomplish the desired results. Areas of agreement between City, County, and private interests are: (a) Batiquitos Lagoon is capable of a wide range of ecological and recreation uses; (b) The lagoon should be opened up to tidal flushing; and (c) Any type of lagoon development will be very costly. Areas yet to be resolved are: (a) Specific uses on the I.agoon proper; (t?) Land uses, both public and private, on lands surrounding the lagoon; (c) Which public agency(s) should be in control; and (d) hIethods of financing by public and/or private interests.

Unfortunately, the implementation of the plan has been weak and has only met with partial success. 26, The 1960 General Plan did not stress linking open space and recreation areas at either a micro or macro scale. The map titled "Potential Linkage and Other Special Features" illustrates potential scenic highway and the use of utility easements as linkages. -.-...- . -- --_I._ -- - 0 -- 0 (d c: k! .d . B. OBSTACLES TO .OPEN SPACE AND CONSERVATION PRESERVATaN Considerable attention has recently been focused on the need to preserve the quality of the environment. Nevertheless, the fol- lowing obstacles must be overcome before the open space and con- servation 1.

Existing techniques of open space preservation are limited in their ability to preserve a comprehensive system of open space. Differing developmental policies, intergovernmental conflicts and competition between local ,governments inhibit the ability to preserve a comprehensive system of open spaces and develop an integrated park and recreation program. The prevailing concept of "private property rights" versus actual State and Federal constitutional limi- tations often leads to exploitation of open space and conservation resources and inhibits local govern- ment's attempts to guide the preservation or develop- ment and use of open space land. Social and governmental contributions to increased land values are not adequately recouped by existing local advalorem assessment practices or by the exist- ing State and Federal capital gains or income taxes. There is reluctance to utilize or even try more compli-, cated open space preservation methods such as scenic and conservation easements, purchase arid sell back without certain development rights, required dedica- tion of less than fee title to land, enforcement of zoning to the legal limit to preserve open space; and, instead, local govcrnments persist in relying on acquisition of full fee, and required dedication of land for local parks. Few resources have been allocated to open space and conservation preservation because open space has been viewed as an amenity rather than an environmental necessity. . 8. The benefits of open space and conservation have been to this point noq-quantifiable, whereas the supposed monetary costs have received more notoriety. 9. The most critical open space and conservation concerns of Carlsbad may be identified as follows: e 8 s 8 0 0 e 8 e Uncoordinatcd multi-jurisdictions and-interest groups, each with their own conccpt of open space and conservation needs and priorities.

Many benefits to be derived by the public from the provision of open spaces, especially conservation, are not subject to monetary remuneration. While citizens enjoy driving through areas of natural beauty, there is no feisible way that they can be required to pay for benefits received. Similarly, while the whole City will clearly benefit if watersheds remain unpolluted and the proper ecological b:.lance is main- tained, no private firm could charge far-providing . such services. Although social benef its gained by providing open space may well exceed costs, no private . firm could make such a venture profitable. 2. For most conservation uses, it is necessary to have large tracts of land. Past experience has shown that private firms are often incapable of acquiring all of the individual parcels that must be combined to form , a site large enough for conservation purposes in the appropriate areas. 3. Many conservation and other open space uses can best be effected by a public agency. In order to achieve maximum benefit from such open spaces, they must fit properly into land use patterns of the area. Zoning, c subdivision regulations, and other development controls must be used in a manner which protects existing open space, and facilitates the addition of more open land as needed. 74 i D. 0PE;N SPACE DESIGN CQN C E PTS I The Opcn Space and Conservation Elements are both immediate and futuristic. Certain features of the elements can be immediately implemented or implemented in the near future, while other. features will require capital outlays over an extended period of time and the continubus application of open spaze/conservation/urban design principles. The design concepts advocated in this general plan are based space is more than formal recreation areas and includes (1) outdoor areas in urban Carlsbad which are open to freely chosen and spontaneous activity, movement, or visual explora- tion of a significant number of city people; and (2) lands in need of special conservation treatment. cept includes places which are not usually green on planners' open space maps, such as vacant lots, median,parkways, small landscaped areas, flood control channels, railroad rightsTof- way, stands of trees, and features that present the image of an open community. . c - on the aforementioned goals, and on the premise that open The design con- Many of the design concepts can be applied both at the micro and macro open space scale. The emphasis at the micro scale is on open space amid and between buildings, streets, parkways, median strips, open space within subdivisions, planned unit developments and c0mmunities;central business districts, industrial parks, etc. including the number of acres to be developed for neighborhood recreation, neighborhood riding and hiking trails, treatment of neighborhood watercourses, open spaces as center pieces around which buildings can cluster, buffers, development of hillsides, preservation of natural features and scenic amenities'. In some cases the amount of land to be left open and that available :€or build- ing can be set as a limitation in percent of lot coverage or in specific dimensions. These limitations need not be con- sidered restrictive, but as conditions for developnent. They set the challenge for development possibilities and ingenious building solutions. The emphasis at the macro scale is on open space for City and regional recreation, major riding and hiking'trails, greenbelts, wildlife, flood and drainage, agriculture, mineral resources, watershed and water recharge, stream valleys, scenic and conservation corridors', lagoons, beaches, golf courses, and linkages to major public open spaces. . An important factor is that open space should always be con- sidered in relation and integrated into the whole hierarchy of scale: the site in relation to its neighborhood, t:he neiglibor- hood in relation to the city, the city in relation to the county and region. It is in the open spaces that one size of area relates directly'to others in the hierarchy of scale, and it is 'in this rclationshp that a system of open spaces develops, from the smaller detail to the larger broader elements of a system, The plan, policies and standards in the Open Space and Conserva- tion Elements reflect a combination of five design concepts at the micro and macro level: Containers, Recreation Cores, Open Space Net, Linear, Natural Features, .- . from the broad scale to the local detail. 1. Containers: This concept suggests that open space could also be applied to limit urban growth to a ' predetermined size by surrounding area within the City with a band or buffer of open space.. This is not a new concept. Around the turn of the century in England, the concept of "new towns" 037 "garden cities" was developed; .whereby each new town was a complete, relatively self-sufficient community sur- rounded by open countryside or a "greenbelt" which served the recreational and agricultural needs of the people as well as limiting further outward devel- opment., Since that time, the concept of new towns has been modified to meet changing social conditions, but the validity of balanced land use has become stronger. This has been especially true in most recent years because of the sprawling low density development which has occurred and the rapidly increasing population demanding more facilities. Using open space as a container of development could work if used to surround existing residential areas or planned communities. < Under this design concept, a significant modification in open space acquisition policies is required. Major land holdings currently designed to meet reccreational or conservation needs would continue to function i,n this capacity. However, the emphasis on new acquisi- tions must be shifted to smaller areas capable of . serving as an integral part of a "greenbelt." This concept would afford the maximum in user-oriented facilities, since the open space system identified in this document is in close proximity to the resi- dential areas. However, the application of the con- tainers approach would be difficult to apply in the existing developed portions o€ Carlsbad. < . . 0 ,L" 2. Recreation Cores: This concept uses open space as the focal point for urban development. Central Park in New York City is an excellent example of this, in that its location, size, and configuration were chosen in terms of serving an urban area and did not relate specifically to water or other natural features. Using this approach, emphasis would be placed upon recreational areas within the urbanized portions of the county such as regional parks and beaches. This, in turn, suggests that new urban growth will .center around or adjacent to these facilities. Open Space Net": Under this design concept an "open - space net" is created by joining major public, quasi- public, and private open spaces into a continuous system, promising increased economy and, efficiency through combined use and increased amenity in the form oi greenhelt parkways. Most of the gains can be achieved without major increases in public expenditures. To be effective, the net must become a central coordi- nating element in planning--not something happening occasionally and in patches by fortunate accidents, but a sustained and purposeful effort. This approach to open space design is applicable to micro as well as macro open space systems. For a balanced system, the open space net approach begins with consideration of open space of regional and citywide significance and works down to the scale of the community and neighborhood level. The net is intended to serve, to separate, and to buffer *in areas where buffering is needed. Where it performs all these functions, its pattern is as follows (See figure titled "Detail Plan and Cross < . Section of Net"): e Border Elements: Collector or arterial street at outer edge of net forming boundary. Close to street, public, quasi-public, and private uses with substantial open space requirements, with space merged to contribute to buffer. *Frederick 11.

Xay contain uses with only minor 0 Linear Core Elements: Limited access highways, The figure titled "The Net and Neighborhoods" is an intentionally generalized and schematic illugtration. It shows what might happen as a result of application of the open space net concept as limited access arterials cut through predominantly residential neighborhoods and as complementary uses, open space, and principal peripheral collector streets are added. 4. Linear: The linear design concept .is implicit in many of the previously mentioned open space design concepts. However, the advantages of a linear open space system have not been explicitly stated. If the major objective of the open space system is to provide people with a maximum amount of visual and physical contact with open space, it is desirable to enlarge the perimeter of the space rather than increase the bulk of it. This requires the design of an open space system involving linear or corridor open space. To illustrate the value of linear open spaces let us take an area-of 4 square miles. If it is all in one piece and roughly square, there would be 8 miles of perimeter. 1 b * 79 ! c 0 If'the 4 square miles consisted of four separate squares of one mile each, you would have 16 miles of perimeter. If the space were a strip 1/2 mile wide:, you would get 17 miles of perim,eter. Per acre, linear strips or corridors are probably the most efficient form of open space. Wheii they are laid along the routes people travel or walk, or poked in to the places where they live, the spaces provide maximum visual impact and maximum physical access.* TO be effective the linear design concept and linkage approach must become a central coordinating element in the environment of Carlsbad. The 1i:nkage approach must not be left to happen occasionally and in patches by fortunate accidents. It requires a sustained a>d purposeful effort. When this is done, the open space and conservation system has dramatic promise, but it becomes apparent that some traditional planning concepts may have to be altered and improved. *William 11. Ifhyte, The Last Landscape, 1968. c' . 5. Natural Features and Processes 'Concept: The thesis of this concept .is that the preservation of natural features and maintenance of natural processes should be viewed as a primary objective of planning, and the planning with the environment will in the long run be more b.eneficia1 to man. These natural pro- cesses are identifiable and are determined- by the laws of nature and constitute a value in themselves. It-is, in fact, essential for man's survival 'that he ,identify and maintain these natural processes for the maintenance of life.. Applying this concept to open space planning suggests thzt lands for open space should be largely made up of areas which have a distinct natural c:haracter. The preservation of such areas would not only maintain natural processes but satisfy open space requirements .such as recreation and visual amenity and also serve the public interest in other capacities. Ian McHarg has expounded this "environmental determinism" approach in many of his writings. It is basica1l.y an ecological approach--economically defensible and serving the recrea- tional and design functions of open space as benefits of its application. - . *- .. . .. .. ._- ." Empirical studies have shown that areas which contain the most significant environmental resources can be identified and ranked according to theiir values. They are.frequently concentrated in a linear pattern, generally coinciding with the drainage pattern. These concentrations have been referred to in this report as "conserv'ation corridors .It As a result, watercourses , . ' flood plains, steep slopes, poorly drained soils, wet- lands, aquifers, important wildlife habitats, and areas of scenic beauty may combine into a system with fairly distinct boundaries. By placing restrictions on the use of these lands, open space can be iinfused into development, and the integrity of natural processes can be preserved. . . E. - Funding Sources One of the main problems in providing open space and conservation areas is the lack of local funds. Acquisition of open areas requires financial assistance from Federal , State, and County sources. The major funding sources include: 1.

It provides match;no grants covering up to 50 percent of the costs of acquiring and developing recreational , conservation, scenic, and historic lands. standstill in reference to new grants and was recently suspended.

However, this program is currently at a 2. Land and l:rater Conservation Fund: Another federal prouram is authorized bv the Land and Water Conservation Act of 1964. It established *a 50-50 matchinq grant program to states for planning, acquiring, and developinq recreational open space lands.

It would generate approximately $75 million (based on 1971-2 sales estimate). and park districts would receive 30 percent of the fund to use at local discretion and 50 percent for specific projects. The state would receive 20 percent, with the California coast being designated as one of the areas of high priority for preservation. 6. Local Bond Issues: It seems clear from the limitations of existing funds- that the great majority of open space acquisition funds .will have to come from local sources, such as aeineral obligation bond fssues. If those bonds can be repaid through methods other than property taxes (such as San Diego's Environtyental Protection Fund, which is derived from the franchise tax on public utilities) they would seem to have a better chance of passage and would not present an added tax burden to property owners.
