PLN CITY DEPTm ATTYV!! CITY MOR=- RECOMMENDED ACTION: Accept the SANDAG Report on Regional Growth Management Recommendations. ITEM EXPLANATION On February 26, 1988 the SANDAG Board of Directors authorized distribution to member agencies of the Draft Regional Growth Management Recommendations for review and discussion. The SANDAG report is attached and it contains five recommendations as follows: 1. Adopt the Series VI1 Population Forecast (to the year 2010) and the first five years (1989-1994) of the Series Seven Housing Unit Forecast as policies for building permit activity by each jurisdiction. 2. Enact (in its final form) the "Sensitive Lands Initiativevv currently being proposed in the City of San Diego and unincorporated areas of the county, as a coordinated and consistent policy for preserving sensitive and natural resource lands in all jurisdictions. 3. Authorize development of new coordinated policies for financing regional serving public facilities and resources. 4. Authorize development of a regional strategy to promote a better balance of .population with employment opportunities in the regions communities. 5. Authorize a comprehensive regional growth monitoring and annual reporting system that would address: regional resource quality and availability, and growth impacts upon the San Diego region. Recommendations 3, 4 and 5 involve authorization from the SANDAG Board to do additional work in studying regional programs and strategies and therefore do not involve policy decisions at this time. Regarding recommendations 1 and 2, SANDAG is requesting that all member jurisdictions accept these as policies to better manage and coordinate growth on a regional basis. It is staff's belief that the overall goal of coordinating the management of growth throughout San Diego County is needed and, as such, Recommendations 1 and 2 are a positive initial step in that direction. Staff is recommending that the City Council accept the Recommendations. Page 2 of Agenda Bill No. 9447 Staff and any additional Planning Commission comments on Recommendations 1 and 2 are contained in the attached memorandum to the City Manager from the Planning Director dated May 19, 1988. Staff also recommends that the City's SANDAG Board representative, Council Member Mamaux, present these comments as well as any additional Council comments to the SANDAG Board. EXHIBITS 1. Memorandum to City Manager dated May 19, 1988 2. SANDAG Report MAY 19, 1988 TO: CITY MANAGER FROM: Planning Director STAFF/PLANNING COMMISSION COMMENTS ON RECOMMENDATIONS 1 AND 2 OF SANDAG DRAFT REGIONAL GROWTH MANAGEMENT RECOMMENDATIONS Recommendation 1 of the SANDAG Report would use the housing unit forecast as identified in the Series 7 Population Forecasts for the next five years as policy for a jurisdiction's share of building permit activity. For Carlsbad, this would equate to 6,438 dwelling units or an average of 1,288 dwelling units annually. There would be no penalty or sanctions if the share was not met or exceeded. Although Carlsbad uses yearly dwelling unit projections in our Growth Management Program, the objective of our program is to equate the amount of growth to the need for public facilities. As a result, the City has adopted a strict Growth Management Program which contains specific facility performance standards which must be maintained at all times in order to allow growth to occur. The recommendations being made by SANDAG do not address the impacts of growth, but only the number of residential units being built by each jurisdiction. In terms of this recommendation's effect on Carlsbad's program, it will have none other than just formally confirming the dwelling unit projections that staff already uses as a planning tool. There are however numerous cities in the county which do not have specific growth management programs and this could be a first effort in getting their cooperation in Regional Growth Management. Staff would recommend that the City make a recommendation to the SANDAG Board of Directors that the next step in this process might be for communities to agree on specific public facility performance standards which all jurisdictions must adhere to. As a starting point staff would recommend the acceptance of a transportation standard or a circulation standard similar to the one adopted in the City's Growth Management Program. In terms of the second recommendation by SANDAG, which is for all jurisdictions to enact the Sensitive Lands Initiative, the City of Carlsbad currently has as part of its Growth Management Plan, numerous provisions which protect sensitive lands in the City. Those ordinances and policies adopted by the City Council actually appear to exceed the requirements of the sensitive lands initiative. Staff is recommending that the City Council urge other cities to adopt similar policies to the City of Carlsbad or that of the sensitive lands initiative. City Manager May 19, 1988 Paae 2 The Planning Commission considered the SANDAG Report at its meeting of May 18, 1988. While the Commission supported the report, they wished it emphasized that it does not supercede the City's growth management approach which is to address the impacts of growth through the adequacy of public facilities. Dwelling unit development activity by itself does not provide for successful growth management and the need to have facility-based performance standards is essential.

San Diego ASSOCIATION OF GOVERNMENTS Suite 524, Security Pacific Plaza 1200 Third Avenue San Diego, California 92101 (619) 236-5300 April?, 1988 The SANDAG Board of Directors authorized distribution of the Draft Regional Growth Management Recommendations at their meeting of February 26, 1988. In their action, the Board clarified the staff recommendation to emphasize that the Growth Management Recommendations were being distributed for "review and discussion" at this time, and that staff would return to the Board in June 1988 with local reaction and, hopefully, a consensus on the Recommendations. The Board also agreed that staff should initiate a round of meetings with the member jurisdictions and other interested parties to discuss the Recommendations. The Board further directed that staff continue to analyze the application and impacts of policies designed to limit the future size of the region so that those options would be more clearly understood if a point in time were reached when these types of growth controls were being actively considered. SANDAG would appreciate your review of these recommendations and encourage your comments.

Department of Defense and TijuandBaja California Norte Sari Diego Auocistion of Governments BOARD OF DIRECTORS February 26, 1988 AGENDA REPORT No.: R-17b DRAFT REGIONAL GROWTH MANAGEMENT RECOMMENDATIONS Introduction This report introduces a set of draft regional growth management recommenda- tions. These proposals are the result of the staff's analysis of growth management issues and options, and its participation with the member jurisdictions on their growth programs since February 1987. The recommendations are intended to provide a cooperative public policy framework so that local growth management plans and policies can be coordinated effectively to the benefit of each city, the County, and the region. They also are an attempt to develop a consensus on growth management policy among local jurisdictions, community leaders, and the public (as reflected in public opinion surveys). The basic objective of the recommendations is to facilitate wise management of the regionk growth so that people's needs are met, quality public facilities are available for their use, and the region's rich envir- onmental resources are permanently protected. The recommendations rely in part on results of analyses conducted on the "carrying capacity" of the region as represented by six regional commodities, resources or types of infrastructure. Shortages or degradation of several resources or facilities currently exist, or will beyond the year 2000. These problems could alter or in- fluence the region's growth rate over either the short or long term. The analysis presents a set of findings on these effects and how these conclusions lead to new growth management policies. "Carrying capacity" is evaluated for (1) water avail- ability; (2) sewerage capacity; (3) solid waste disposal capacity; (4) air quality; (5) transportation system adequacy; and (6) energy availability. The resultant findings support the conclusion that new growth management policies should be considered. The report concludes with an expanded discussion of the draft growth management recommendations. The recommendations are: 1. Adopt the Series 7 population forecasts (to 2010) and the first five years (1989- 1994) of the Series 7 housing unit forecasts as policies for building permit activity by each jurisdiction. 2. Enact (in its final form) the "Sensitive Lands Initiative'' currently being pro- posed in the City of San Diego and the unincorporated area of the County, as a coordinated and consistent policy for preserving sensitive and natural resource lands in all jurisdictions. 3. Authorize development of new coordinated policies for financing region- serving public facilities and resources. -..- 4. Authorize development of a regional strategy to promote a better balance of population with employment opportunities in the region's communities. 5. Authorize a comprehensive regional growth monitoring and annual reporting system that would address: regional resource quality and availability, and growth's impacts on the San Diego region. It is my RECOMMENDATION that, based on the findings relative to the carrying capacity in the San Diego region and the considerable public interest in regional growth management, the Board of Directors of the San Diego Association of Governments accept this report on Draft Regional Growth Management Recommendations for distribution to (1) the local jurisdictions for review and consideration for adoption; and (2) the City of San Diego's Citizens' Advisory Committee on Growth and Development and the County of San Diego's Regional Growth and Planning Review Task Force for review and consideration for recommendation to their respective governing bodies. The staff should also schedule briefings with member jurisdiction councils and the Board of Supervisors on these findings and recommendations. Discussion This report on the carrying capacities and draft growth management recommen- dations for the region is based on a year's work in SANDAG's cooperative growth management evaluation project with the County and City of San Diego. The County's Regional Growth and Planning Review Task Force and the City's Citizens' Advisory Committee on Growth and Development will present growth policy rec- ommendations relative to existing plans and policies to the Board of Supervisors and City Council in late Spring. SANDAG's efforts in assisting these groups and other interested jurisdictions in the region include conducting public opinion surveys on attitudes toward growth; evaluating the costs of regional infrastructure and other public facility implications of future growth; identifying and analyzing the impor- tant external and internal factors which cause the region to grow; coordinating and monitoring growth management strategies and activities among the region's 19 jurisdictions; and examining possible methods for financing regional public facilities and resources. In addition, this report provides the basis and demonstrates the need for develop- ment of short-term growth management policies to allow workable planning and management of the growth that will inevitably come to the region. Development of new public policy recommendations to help manage and finance long-term growth is included as well as the long term, continuous monitoring of the region's growth. Monitoring the growth of Southern California and Baja California will enable the region to determine when its share of those regional resources and commodities might be constrained, and to respond appropriately. The following is a summary of the analysis of the carrying capacities for the six categories listed above: 2 1. 2. 3. 4. 5. 6. WATER AVAILABILITY Areas of Southern California receiving their primary water supplies from the Metropolitan Water District (MWD) and the San Diego County Water Authority (CWA) could experience shortages between now and 2000, and beyond, partic- ularly if California and the Colorado River basin have periods of below average precipitation during those years. SEWERAGE CAPACITY The North County has current sewage capacity to accommodate growth until about 2005. The San Diego Metro System, however, requires an expansion of its treatment capacities now as it is converted to a secondary level of treat- ment to accommodate growth. SOLID WASTE DISPOSAL CAPACITY Solid waste disposal capacity will be exceeded in the next ten years unless major new facilities are successfully sited and recycling programs initiated in the region's urban areas. AIR QUALITY Although the region's air quality has improved, the San Diego air basin is not currently in compliance with federal standards for air quality. TRANSPORTATION SYSTEM ADEQUACY The recent growth in automobile travel has had a significant impact on the region's freeway system. Projects proposed over the next 19 years will main- tain mobility in the region by providing additional transit and highway facilities in the most heavily congested corridors. Transit access in 2005 will be signifi- cantly better than it is today; highway access, however, will be somewhat worse. The region's airport system will be at its capacity in 2005, and major new facilities will be required if growth beyond that time is to be accom- modated. ENERGY The region's energy supply infrastructure will have to be significantly expanded in order to meet growth expected by 2005. The need for new infrastructure will be particularly critical in meeting the growing demand for peak electric supply. The region will need to add 970 MW of peak electric power to balance demand and supply, and there are currently no identified sources for the power. CONCLUSION It is clear that regional resources and the region's ability to accommodate growth will be impacted by strains placed on those resources by projected growth. Shortages or constraints will occur in several major regional resource areas including transportation, water availability, and peak energy supply. Furthermore, the costs of providing necessary facilities for solid waste and sewage disposal are high. Attaining federal air quality standards and maintaining those standards will be costly and will require changes in travel behavior of the region's residents. 3 Shortages of regional commodities such as power and water would affect the ulti- mate size of the region; transportation system congestion or continued air quality problems probably would not. But for the reasons stated and the concerns evi- denced by growth management actions of many of the jurisdictions in the region and the concern over growth demonstrated by public surveys and current citizens initiatives, new growth management policies on a regional level should be con- sidered. These recommendations do not call for actions to arbitrarily reduce the region's future population growth. The actions would, however, assure accommodation of forecast growth at a historically manageable rate for the next five years. This rate would be less than that of the rapid growth period since 1983. Simultaneously, SANDAG and local governments should cooperate to monitor regional and local growth and its environmental and economic impacts. It is pos- sible that within the next ten years new findings on regional carrying capacity will cause a re-evaluation of a strategy of accommodating growth at a manageable rate, and consideration of policies to reduce the region's long-term growth rate will be necessary. This is not the case at the current time, however. The following section of this report describes a set of draft growth management recommendations which could be utilized by the region's jurisdictions as elements of a cooperative regional growth management strategy. ACTION 1 EACH JURISDICTION SHOULD ADOPT: (a) THE SERIES 7 POPULATION FORE- CASTS (TO ZOlO), AND THE NEXT FIVE YEARS (1989-1994) OF THE SERIES 7 HOUSING UNIT FORECASTS AS POLICIES FOR BUILDING PERMIT ACTIVITY. Why Undertake This Action? The need to establish a consensus on a manageable rate of regional growth, and how the region's jurisdictions would share that growth, has emerged as a primary issue at the regional level. The region's growth rate from 1983-87 (an average of 61,000 persons per year/about 3.1%) has taxed the ability of governmental agencies to meet environmental and facility provision demands, accelerated crowding of public and private facilities, and generated growth management policy actions by 13 of the region's 19 general purpose agencies in response to public interest in "doing something about rapid growth." The Regional Growth Forecasts represent the amount of growth the region is likely to have, based on a combination of local, state, and national demographic and economic trends. Since 1972 the Forecasts have accurately predicted the region's total growth. An average year of these forecasts represents a growth rate that public and private entities have traditionally been able to deal with; and one in which environmental and economic safeguards need not be exceeded. By adopting the dwelling unit totals developed in the Forecasts, for a five year period, and using these as public policies to guide building permit activity, cities and the County accommodate a normal share of future regional growth, but at a rate that avoids adverse economic and environmental impacts and does not impose artificial caps on local housing development. There are other reasons to take this action: 4 The action represents a timely, coordinated, and pro-active response by the local jurisdictions to growth pressures. It enables clear understanding of the interjurisdictional impacts of each com- munity's growth and forecloses the necessity to consider defensive local ordi- nances. It gives local agencies the flexibility to take advantage of the housing market and market condition changes over a five-year period. It demonstrates that local jurisdictions are accepting a share of regional growth based on a cooperatively prepared forecast. Consequently, the action should help local agencies avoid grow th-related litigation. The action enables cities and the County to accurately forecast the five-year need for public facilities and to better phase the financing and development of facilities. The action avoids artificial caps on local housing development. SANDAG research has shown that individual jurisdiction housing caps have no effect on regional growth, tend to cause a local disproportion of employment and housing mix unless coupled with job reductions, and have adverse social impacts by limiting availability of new and used housing. Limiting housing availabililty drives up prices and rents, and those increases are felt disproportionately across the population. The action provides jurisdictions with a tool to coordinate building permit activity with local general and community plans, and to integrate public facilities and other improvements. How the Action Could Be Implemented Each jurisdiction would adopt a total number of dwelling units for the five-year period from 1989-1994 based on the Series 7 Forecasts for those years. The Fore- casts, which predict occupied housing, would be adjusted upward for vacancy rates. Table 1 includes 1987 data for each jurisdiction and housing completion and authorization data for 1986, a year of very rapid population growth. The table also shows the 1989-94 dwelling unit totals from preliminary Series 7 and the five year and annual activity allocations which the jurisdictions would be asked to consider. Table 4 describes recent, historic, and forecast growth of housing. 5 5 d t U 6 TABLE 2 INCREASE IN HOUSING SUPPLY SAN DIEGO REGION 1970-2010 Series 7 Total' To tal2 Total' Average Average Average Dwelling Dwelling Dwelling Annual Annual Annual Units Units Units Change Change Change 1970 - 1984 1987 ' 1970-87 1984-87 1986-2010 4 5 0,7 9 8 763,085 855,545 24,164 30,820 19,546 1. U.S. Census, 4/1/70 2. Estimated 1/1/84 and 1/1/87 Each jurisdiction would be responsible for allocating the total units throughout the five-year time period as demand or public policy dictates. This gives the oppor- tunity to let the private market adjust to interest rate and market cycles. It is also useful for predominantly developed communities that have large new projects or major redevelopment projects only every few years. The annual averages, which are based on General and Community Plans, indicate about how much housing constitutes a jurisdiction's share of anticipated five-year growth and its housing needs. They are by no means, however, performance standards that need to be met in any one year. ACTION 2 ENACT (IN ITS FINAL FORM) THE "SENSITIVE LANDS INITIATIVE" CURRENTLY BEING PROPOSED IN THE CITY OF SAN DIEGO AND THE UNINCORPORATED AREA OF THE COUNTY, AS A COORDINATED AND CONSISTENT POLICY FOR PRESERVING SENSITIVE AND NATURAL RESOURCE LANDS. Why Undertake This Action? Behind transportation problems, the public perceives the change in the region's face as the most disagreeable impact of rapid growth. Develoment of slopes and flood- plains, loss of sensitive lands, excessive grading, habitat clearing, and view encroachment are mentioned most often as adverse impacts. Every jurisdiction has requirements for dedication of related open space concurrent with development, and many have overlay zones or other regulations to protect specific resource areas. However, coordinated and consistent policies on a regionwide basis would more effectively respond to the public's concern. Enactment of a common final version of the Sensitive Lands Initiative by all 19 jurisdictions would have several distinct advantages. o The action would create consistent local policies for dealing with open space and sensitive lands, which would be valuable to both public agencies and the development community. 7 The action uses as a model a document designed by a citizens group in response to strongly held citizen opinion. Consistent sensitive lands policies enable local agencies to plan more effec- tively for important river corridors and other contiguous open space areas which cross jurisdictional boundaries. Cooperative plans such as the one cur- rently being prepared for the San Dieguito Valley would be much easier to prepare and implement. Coordinated policies to protect habitat, wetlands, and other threatened resource areas will help resolve conflicts bet ween proposed public improve- ments and endangered species and habitat loss regulations of state and federal agencies. The action would preserve irreplaceable resources which are important contri- butions to the region's quality of life. Additionally, implementation of conser- vation policies can focus public and private sector resources on sensitive lands in ways which benefit all involved parties. How the Action Would be Implemented The Sensitive Lands Initiative petition is currently being circulated by an environ- mental interest group called San Diegans for Managed Growth. The group's current intention is to place the Initiative on the ballot in November 1988 in San Diego and the unincorporated area of the County. A synopsis of the Initiative follows this section. It is not currently known whether or not the initiative process will be pursued in the other cities, if some jurisdictions will choose to enact the Initiative through local ordinance, or if the Initiative will be modified as a result of nego- tiation between the proponents and local governments. In any case, the Initiative is a reasonable basis for a coordinated regional policy and in its final form the cities and County would benefit from uniformly enacting it. In response to enactment, SANDAG would undertake a project as part of the Re- gional Open Space Plan to cooperate with the jurisdictions to identify and map lands subject to the initiative, resolve any definitional or resource questions, and monitor the sensitive lands resource regionally. Summary of Sensitive Lands Initiative This initiative is currently being circulated in both the City of San Diego and un- incorporated portions of the County to qualify for the November ballot. The specifics of these two initiatives are: o Creation of a Resource Conservation Overlay Zone based on an inventory of all sensitive lands including, at a minimum, wetlands, floodplains, steep hillsides and canyon slopes, critical habitats, areas of native vegetation, and significant archaeological or historical sites. o Specific regulations/permits for any activity within this Overlay Zone, with the following permitted uses for each category. 8 Wetlands - aquaculture, scientific, educational or recreational uses if not harmful to the ecosystem; restoration projects; essential public service projects or water4ependent public facilities if no viable alternatives exist, with mitigation measures resulting in a net gain in functional wetlands; Wetland Buffers - access paths, improvements necessary to protect adjacent wetlands and/or health, safety and general welfare; Floodplains - agriculture, low intensity recreational uses; grading and filling of floodplains in public ownership for essential public facilities if no viable alter- natives exist providing mitigation results in a net gain in functional wetlands and riparian habitat; no permanent structures, fill or grading for purposes other than habitat restoration will be allowed. Steep Slopes - one residential unit per .96 acre (40,000 square feet) on 25% slopes; one unit per 10 acres on 50%+ slopes; limits encroachments on sliding scale based on steepness of slope for specific-public projects if no viable alter- natives exist, based upon public hearing and finding by Planning Director that such encroachment is consistent with intent and purposes of this Initiative. ACTION 3 AUTHORIZE DEVELOPMENT OF NEW COORDINATED POLICIES FOR FINAN- CING REGION-SERVING PUBLIC FACILITIES AND RESOURCES. Why Undertake This Action? At this meeting the Board of Directors will begin discussing financing some selected categories of public facilities and desirable public resources at the regional level. The companion report points out that there are several types of facilities which are provided regionally and could potentially be financed all or in part, more effectively through a regional source. These public facilities could include sewage treatment, transportation, courts and jails, solid waste manage- ment, public schools, and others; development and acquisition of regional resources such as open space or low income housing could also be financed at the regional level. The Board is requested to authorize staff to complete a feasibility analysis of regional financing and develop draft policies during FY 1988-89 as a part of the Overall Work Program (OWP). The policies would have to address: Identification of facility financing options equitable to new and existing resi- dents. Lack of money for both capital and operating costs. Financing open space acquisition. Pooling the agencies' ability to finance needed improvements. Encourage public/private partnership and innovation in developing regional facilities. 9 ACTION 4 AUTHORIZE DEVELOPMENT OF A REGIONAL STRATEGY TO PROMOTE A BETTER BALANCE OF POPULATION WITH EMPLOYMENT OPPORTUNITIES IN THE REGION'S COMMUNITIES. Why Undertake This Action? Since the adoption of the first Regional Transportation Plan in 1974, the concept of economically balanced communities has been considered an important way to mitigate adverse impacts of population growth. Recent research has also cor- roborated the dominant role that employment and job creation have in regional growth. The Series 7 forecasts show that the character of work trips in the region is changing as residential development and employment centers grow farther apart. The San Dieguito River crosses 1-5 in north Del Mar and 1-15 at Lake Hodges. If an imaginary line were drawn between these two points, one out of every four people living north of the line commute south of it to their place of employment; in 1985, about 83,500 daily trips on the two freeways. By 2010, this ratio becomes slightly larger and the actual number of trips increases to 164,500 per day. This increase in the number and length of work trips has obvious implications for air quality and energy consumption as well as freeway congestion. Better economic balance of communities would positively address this growing problem but shouId also address other existing problems including uncoordinated and potentially un- productive expenditure of local money on industrial land development and an over- abundance of industrially zoned land in certain parts of the region. On this last point, Series 7 shows that over the next 25 years the region can expect to develop about 350 industrial acres per year. In 2010, however, an inventory of 10,500 industrial acres remains vacant and unused. As with Action 3, the Board is requested to authorize a job as part of the OWP that will focus on drafting a set of coordinated actions which local jurisdictions could take to improve the ability of residents to live and work in the same community. The job will also develop a methodology to better balance economic development and industrial land creation with housing growth. ACTION 5 AUTHORIZE A COMPREHENSIVE REGIONAL GROWTH MONITORING AND ANNUAL REPORTING SYSTEM THAT WOULD ADDRESS: REGIONAL RE- SOURCE QUALITY AND AVAILABILITY; AND GROWTH'S IMPACTS ON THE SAN DIEGO REGION. Why Undertake This Action? If the region's jurisdictions decide to adopt policies to cooperatively manage future growth, an annual monitoring and reporting system will be necessary. Regular reporting to the Board of Directors would enable the jurisdictions to actively monitor changes in the growth rate, economic and demographic trends, and both interjurisdictional and extra-regional impacts of growth. Successful management of the region's future growth requires a balance of policies which simultaneously 10 .- control some activites related to growth while encouraging others. Economic, environmental, social, and other impacts may be either negative or positive and only regular monitoring and reporting allows elected officials to be aware of these trends and assures the public that growth management issues are being actively addressed. The Board's action on this item is to authorize inclusion of the monitoring process as an expansion to the FY89 OWP. The regional growth management monitoring and reporting process would evaluate two distinct areas of interest and concern on at least an annual basis: Regional Resource Quality and Availability - - - Annual monitoring of energy and water availability Continued monitoring/forecasting of air quality standards attainment Annual updating of regional infrastructure cost and regional ability to Pay Preservation/development of open space and sensitive lands. Growth of the five Southern California counties and Tijuana compared to regional resource quality and availability - - Growth of the San Diego Region - Dwelling unit approval/development consistency with Series 7 (moni- - Commercial and industrial floor space approval/development as a - - - toring of Action 1) measure of job creation Changes in employment and housing ratios in the region's subareas Impacts of growth management policies Regular evaluation of the Regional Growth Forecasts. ACTIONS NOT RECOMMENDED FOR 1988 In the process of studying regional growth and its potential for effective manage- ment, the County, cities and SANDAG have identified a number of possible strat- egies which are not recommended for action. It may be necessary to review these or other actions in the future, as is discussed in the section of this report on carrying capacities, if it becomes clear that it is necessary to reduce the ultimate population of the region. The need is not clear at the current time. o Housing Caps Are Not Recommended Housing caps which are intended to reduce the ultimate size of the region's population are directed at a symptom of growth rather than a cause. In addi- tion to the adverse housing supply, cost, and unequal economic impacts already discussed, the long-term effects of artificial housing caps on other social and economic factors of the region are poorly understood. Additionally, housing caps need to be extremely restrictive if they are to have a noticeable impact. In the "Causes of Growth" report released by SANDAG in September 1987, it was shown that using residential supply controls alone in order to slow growth to a rate similar to that of California (about 34,300 persons per year), new housing would have to be limited to 5,000 units per year. Series 7 forecasts that an average of about 20,400 units will be built each year between 1985 and 2010. Of these homes, 5,900 units per year will be needed to house the off- spring of the 2.4 million people already here and would be required if no new migrants entered the region over the next twenty-five years. o Employment Development Restrictions Are Not Recommended If reduction of the future size in the growth rate became necessary, restric- tions on employment development would be the single most effective means to achieve this. The "Causes of Growth" report showed that 60% of the region's population growth is directly attributable to in-migration associated with the creation of new jobs. Creation of jobs is, however, the result of a robust economy and in the public opinion survey and subsequent discussions with community leaders, there was no interest in job growth restrictions in the region or in limits on commercial and industrial floor space. Perhaps most importantly, the positive or negative impacts of this type of economic manipulation are not well understood. Data are not readily available on the amount of employment growth needed to assure a viable regional economy, and how job reductions cut across social and economic components of the community are not known. POTENTIAL COMPLEMENTARY ACTIONS Other growth management strategies were suggested that could be reviewed at a future date and which could complement the recommended set of cooperative regional actions. They include: o Coordination of local development and infrastructure financing fees among the general purpose agencies. o Similar coordination of the process and procedures to modify general and community plans. o Continuation of the process to develop and adopt consistent regional policies on urban development which occurs on the periphery of existing cities, and on development of new non-contiguous communities. o Development of a process for coordinating growth and impacts research among the five Southern California counties. Executive Director 12 ATTACHMENT 1 This attachment provides additional detail to the carrying capacity analysis included in the discussion section of this report. 1. WATER AVAILABILITY Areas of southern California receiving their primary water supplies from the Metropolitan Water District (MWD) and the San Diego County Water Authority (CWA) could experience shortages between now and 2000, and beyond, partic- ularly if California and the Colorado River basin have periods of below average precipitation during those years. Data published by both Metropolitan and the Authority support this conclusion. Existing Conditions The CWA and MWD are independent agencies, and although the Authority receives almost all of its water from the larger provider, the two organizations prepare independent forecasts of water availability in their respective service areas. Interpolation of the data contained in Table 1 for 2005 shows a poten- tial shortage of 770,000 acre feet, 19% of MWD's forecast demand. This amount of water would serve a population of 3,500,000. Table 2, derived from data provided by CWA, quantifies this region's shallow water resources, showing the San Diego region's demands roughly equal to available supplies.

It is unusual, though not unheard of in this country, for a large metropolitan area to have this much uncertainty about its existing and future water supply. The root cause of the uncertainty, of course, is the area's need to import most of its supply. At our current rate of use, if we had to live on our own water production, the area could accommodate only about 150,000 people. Furthermore, CWA's projec- tions of demand presented in Table 2 are predicated on maintaining our water use at the current level of .22 acre feet per person per year. In fact, our per capita water use has been increasing generally since 1959, and has gone up in each of the past four years. Maintaining a use level of .22 through 2005 pre- sumes that people will improve their water conservation practices almost immediately and that many will change their home and business landscaping. The San Diego region is, naturally, a coastal desert. Southern Californians traditionally have ignored water issues, preferring to leave them to the "water people." Obviously, the "water people" at agencies such as MWD and CWA have done a good job: the water has always been there when we turn on the tap. However, we would be making a mistake merely to assume that alternative sources of supply will necessarily be available to make up for future shortages in imported water. The water supply agencies need support now both locally and in Sacramento. Alternatives/Mitigation At the local level, water conservation can be increased to help mitigate short- ages. Approximately one-half of the region's municipal/industrial water is used for outdoor activities, such as landscape maintenance. Use of xeriscaping, native or drought-resistant plants, is the most effective method of reducing outdoor water use. Local jurisdictions will eventually mandate the use of 2 2. drought-tolerant plants in new landscaping. Drought tolerant landscaping can be as attractive and functional as high water using vegetation. Wastewater reclamation could produce a significant "new" supply, and the region should increase its use as a substitute for imported water wherever possible. Reclamation might ultimately be mandated for certain uses, partic- ularly outdoor irrigation of large areas. An ongoing, cooperative effort involving the League of California Cities, the County Supervisors Association of California, the California Councils of Gov- ernments, the Southern California Water Committee, and others is needed to develop consensus on water policy which would be recognized by the State Administration and the Legislature as the direction water management should take. Following that consensus, water development and management programs are needed. SEWERAGE CAPACITY The North County has current sewage capacity to accommodate growth until about 2005. The San Diego Metro System, however, requires an expansion of its treatment capacity now to accommodate growth as it is converted to provide a secondary level of treatment. Existing Conditions Sewage collection and treatment service is provided by 38 different agencies throughout the urbanized areas of the region. Historically, additional service agencies have been created as the need arises. The largest agency is the San Diego Metropolitan Sewerage System (Metro) which currently serves more than seventy percent of the region's population through 15 member agencies. The Metro system operates the region's largest sewage treatment plant, located at Point Loma. Current daily flows at the plant are about 165 million gallons per day (mgd). Metro was designed to ultimately treat 234 mgd but has installed facilities to treat only about 120 mgd. Metrok discharge permit allows the additional flow to be treated as long as ocean water quality standards are met and other specific steps are taken. Metro's current National Pollutant Dis- charge Elimination System (NPDES) permit issued by the Regional Water Quality Control Board in March 1985 expires in 1988, when new federal dis- charge requirements will be in effect. The City of San Diego is currently involved in the planning and design of new treatment facilities that would accommodate both the projected need and the federal and state water quality standards. Three other agencies operate treatment plants with ocean outfalls: Oceanside, Encina and San Elijo. Together, the four facilities have a current design capacity of approximately 303 mgd, and serve some 93% of the region's households. Flows in 1986 were 207 mgd. New federal water quality standards require secondary treament and all four outfalls have committed to making this expensive conversion. Encina has already installed secondary treatment and both Oceanside and San Elijo can accommodate the additional facilities at their existing sites. Metro, however, cannot and will be required to construct a new plant(s) at a separate site(s). They have a combined capacity of 69 mgd. 3 2005 Conditions By 2005 the four systems will be required to provide total treatment capacity of 273 mgd; 199 mgd at Metro. Upgrading to secondary treatment will allow the rather small (5 mgd) additional capacity needed by the North County plants to be developed. Metro, however, intends to expand to 240 mgd of actual capacity at one or more sites. The 314 mgd of total capacity would serve the region well beyond 2005; however, development of time consuming and costly facilities must be sited and financed before this excess capacity will be a reality . . Alternatives/Mitigation Partial mitigation for the high costs involved in providing a new treatment plant could be utilization of the higher quality effluent for reclamation or reuse, thereby providing an additional source of water to the region. Aqua- culture is another alternative method that could eventually lead to water recycling. 3. SOLID WASTE DISPOSAL CAPACITY Solid waste disposal capacity will be exceeded in the next ten years unless major new facilities are successfully sited and recycling programs initiated in the San Diego region. Ex is tinp Conditions The City and County of San Diego are the two agencies responsible for solid waste disposal facilities in the region. The County owns five sanitary landfills which are operated by private contractors. It has approved the construction of a solid waste recovery plant at the San Marcos landfill which could be in opera- tion as early as 1990. The City of San Diego owns and operates two landfills. Current capacity at the landfills is about 56 million tons. Both the City and County of San Diego recognize that annual solid waste generation rates, currently 1.49 tons per capita are expected to increase to 1.77 tons per capita by 2005. If this forecast is accurate, additional solid waste disposal capacity must be developed. In response, local governments are initiating aggressive recycling programs, searching for new landfill sites, and exploring alternative technologies for solid waste processing and disposal. These include waste to energy processes and new recycling materials and markets based on currently unrecyclable components of the waste stream. 2005 Conditions New solid waste disposal facilities and recycling programs will be needed before 2005 to provide capacity for the region. Capacity will run short in the late 1990's if no new actions are taken. Implementation of the San Marcos landfill resource recovery project and approved local government recycling programs should extend capacity past the year 2000. However, based on current forecasts of waste generation, by 2010, additional new facilities and programs will be required. 4 A1 ternativeslMitigation Efforts are now underway in three areas to add the new solid waste disposal capacity that the region will need: o Implementation of extensive recycling programs (to reduce annual solid waste disposal needs by 20 to 30 percent); o Exploration of alternative solid waste processing and disposal technol- ogies; o Search for new land fill sites. Development of sources of financing is a key issue for local governments in all three areas. Interjurisdictional cooperation, particularly in the financing of recycling programs, will also be an important requirement. 4. AIR QUALITY Although the region's air quality has improved, the San Diego air basin is not currently in compliance with federal standards for air quality. Existing Conditions The Environmental Protection Agency (EPA) is expected to issue a policy by mid-1988 to continue implementation of the Act, requiring new state plans showing how each air basin will achieve the national ambient air quality stan- dards for ozone and carbon monoxide. The plans must demonstrate how the air basin will be in attainment by 1995, and maintain national air quality standards through 2005. Measures requiring an average annual reduction of 3 percent in emissions will be implemented until the national standards are met. In 1982, the region adopted four transportation strategies designed to reduce vehicle emissions and bring the region into attainment with the national air quality standards. Those strategies are: ridesharing, transit, bicycle travel, and traffic improvements. These four tactics were projected to reduce 1986 reactive hydrocarbon emissions by 2.129 tons per day and carbon monoxide emissions by 24.76 tons per day. However, in 1986, the actual reductions were 7 percent of the plan for reactive hydrocarbons and 9 percent of the plan for carbon monoxide. Since 1977, there has been a steady improvement in the region's air quality due mainly to control of fixed source emissions, cleaner fuels, and inspection and maintenance of pollution control devices on automobiles. For the period 1985- 1987, there were no violations of federal standards for carbon monoxide, nitrogen dioxide, or sulfur dioxide, although the state standard for nitrogen dioxide was exceeded once. In 1987, the region experienced 40 days during which ozone levels exceeded federal standards, 14 of which were attributable to local sources, and 26 which resulted from ozone transported from the South Coast (Los Angeles) air basin. Beginning in 1988, the San Diego air basin will have to begin reduction of pollu- tants to meet federal standards by 1995. In order to achieve this, not only will 5 existing transportation tactics to reduce pollutant levels need to be more effective, but new and stricter controls on auto use and emissions will have to be implemented. The measures to achieve the emission reductions will be developed in 1988-1989 and the adopted measures will be included in the 1990 State Plan and presented to EPA for approval. 2005 Conditions The San Diego air basin must meet federal air quality standards by 1995, and maintain that status thereafter. For those air basins not in attainment, EPA may well issue sanctions which could include inhibiting growth in the regions in which they are imposed. Sanctions authorized by the Clean Air Act include bans on construction of stationary emission sources and withholding grants for transportation projects and sewage treatment plants on the assumption that these may encourage growth. Restriction of participation in these programs would affect the region's ability to accommodate forecast growth. A number of measures may be implemented to assure attainment of federal air quality standards, some at the federal level, but most on the local level. For example, federal requirements may result in automobiles operating on alter- native fuels, while at the state level, vehicle inspection and maintenance may be required annually. In order to attain clean air standards, the State of California and the San Diego region will be required to adopt and implement measures to reduce emissions. As previously stated, reductions of 3 percent per year are required, after full mitigation of growth. If the San Diego region's emissions were to increase by 2 percent per year due to growth, the average annual reduction in pollutants would need to be 5 percent to meet and maintain EPA requirements. Alternatives/Mitigation California currently has the strictest air quality standards and pollution control measures in the country. Various tactics or measures which would assist the region in attaining federal standards include (not necessarily in priority order): 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. voluntary no-drive days trip reduction ordinances employer-based transportation management (including tax incentives for employer programs) improved public transit parking management programs park and ride/fringe parking work schedule changes road pricing (tolls) traffic flow improvements rideshare incentives control of extended idling of vehicles gasoline fuel alternatives conversion of fleet vehicles to cleaner fuels or engines reduction of cold start emissions. 6 On the national level, enhanced programs for vehicle inspection and main- tenance and other emission control standards at stationary sources such as municipal landfills may be required. 5. TRANSPORTATION SYSTEM ADEQUACY The recent growth in automobile travel has had a significant impact on the region's freeway system. Projects proposed over the next 19 years will main- tain mobility in the region by providing transit and highway facilities parallel to those which are expected to be most heavily congested. Transit access in 2005 will be Significantly better than it is today; highway access will be some- what worse. The region's airport system will be at its capacity in 2005, and major new facilities will be required if growth beyond that time is to be accommodated. Existing Conditions Freeways - During peak periods, significant portions of the region's freeway system are over capacity. For these routes, the population has exceeded the holding capacity of the freeway network, resulting in slower-than-optimal speeds or transfer of trips to a less congested time. 1-8 in Mission Valley has been congested for years, while 1-5 north of Sorrento Valley and SR78, with a near doubling of traffic since 1980, have more recently become congested. Other portions of the system, such as the South Bay Freeway, 1-5 north of Encinitas Boulevard, and 1-15 north of Rancho Penasquitos, retain adequate capacity . Streets and Roads - The condition of local streets and roads is similar to that of the freeway system. Much of the local network is relatively free-flowing, even during the peak hours. However, many major streets, such as Friars and Mission Gorge Roads, have been congested for years. In general, the growth of travel on local streets and roads has been less than the growth on freeways in recent years. Funding shortages since the late 1970's have decreased the ability of cities to expand the local street system. Local jurisdictions report a backlog of a half billion dollars in local street maintenance and construction projects. Transit - With few exceptions, the region's transit system operates at less than capacity. The bus system, however, because it operates on the streets and freeways, is affected by the congestion of those facilities. Aviation - The region's airports have sufficient capacity to handle the existing demand, although some delay does occur during peak periods. However, one factor affecting the holding capacity is aviation-generated noise. With minor exceptions, the general aviation airports conform to state noise standards. Lindbergh Field, on the other hand, is operating under a noise waiver from the state. 2005 Conditions Congestion on the region's freeways and local streets will have increased significantly over existing conditions by the year 2005. In addition, general 7 aviation airports and Lindbergh Field's single runway will have reached capacity. Only the transit system, with the exception of local buses, will have adequate capacity to serve projected needs. Freeways - Even with the full implementation of the year 2005 freeway net- work adopted in the 1986 RTP, congestion on the region's freeway network will increase. The peak congestion periods will lengthen on most freeways in the urbanized areas. Heavy congestion is expected to spread to 1-5 in Sorrento Valley and in National City, and to 1-5 near Rancho Bernardo. The newer facilities - SR76, SR56, SR52 and SR125 - are projected to remove signifi- cant amounts of traffic from existing routes. Nevertheless, within the urban- ized area, nearly all of 1-5, 1-15, 1-8, 1-805, and SR94 will be at least moder- ately congested. With the improvements proposed for SR78, conditions on that freeway are anticipated to be better in the year 2005 than they are today. Construction of SR52 and the Mission Valley Trolley extension, will prevent any significant deterioration of travel on 1-8, while congestion on SR94 will improve somewhat with the reconstruction of SR54 and the East Urban Trolley extension. Many areas are attempting to deal with congestion by changing commuting patterns. Carpools, staggered work hours, and incentives for utilizing transit are a few examples of strategies being used. The City of San Marcos has implemented an ordinance requiring employers to seek reduction of peak hour vehicle trips by their employees. The City of San Diego is currently studying similar regulations. During FY89, SANDAG will be developing a regionwide demand management program. This program will be developed in cooperation with its member agencies, and will build on the previous efforts of San Marcos, San Diego, the County, and the North County Traffic Demand Management Task Force. Streets and Roads - Congestion on local streets has not been documented in the same comprehensive manner that freeways have. As stated above, it is known that travel on freeways has been growing at a much faster rate than travel on streets and roads. However, it is expected that this trend will reverse as more of the freeway system reaches capacity. In developing the Proposition A program, each City and the County developed a program to accommodate the projected 2005 population. Prop A, with other known revenue sources, will fund only 60% of this identified need. In view of projected growth and large funding shortfall, the rate of increase in congestion on the street and road network is anticipated to be worse than that on the freeway system. Transit - With the proposed expansion of the region's rail and bus system, adequate capacity should be available to accommodate year 2005 demand. The rail system and the 1-15 High Occupancy Vehicle lane will permit the transit system to avoid many major areas of congestion. However, local buses, which will carry a majority of the transit riders, must continue to operate on local streets and will be subject to significant delay during peak periods. Aviation - Planned expansion of existing airports should accommodate the anticipated demand through the year 2005. However, beyond that date, an 8 additional general aviation airport will be needed and Lindbergh Field's single runway will be at capacity. Comprehensive Land Use Plans for the larger general aviation airports should ensure that noise impacts from these facilities will not increase. Depending on aircraft technology, noise impacts of Lindbergh Field may actually decrease, even with a significant growth in the number of flights. Alternatives/Mitigation The Regional Transportation Plan (RTP) proposes a balance of transportation improvements aimed at correcting existing system deficiencies and accom- modating growth. The highway system improvements are planned to more directly connect employment centers to residential areas (SR52) or provide additional capacity at major points of congestion (the 1-5/1-805/SR56 inter- change). The transit system is designed to provide additional capacity in already congested corridors to both relieve existing demand and accommodate growth. However, it is unlikely that San Diego will ever return to the free-flow con- ditions which characterized the region in the recent past. Trends over the past few years indicate that car ownership and the length and number of trips per resident are increasing more rapidly than the population. The RTP does not attempt to maintain the current level of automobile access. The facilities which would be needed to maintain these levels are simply beyond the financial resources of the region. The RTP does attempt to maintain personal mobility through the provision of transit services and through better management of existing and new transportation facilities. Traffic system management, including peak hour traffic management, and coordinated land use and transportation planning, hold the most promise for mitigating current and future traffic congestion. Land use regulation could decrease the need for new facilities. Employment growth in areas of significant congestion could be discouraged or prohibited. Employment could be encouraged in areas served by less congested freeways, and with good transit service. 6. ENERGY The region's energy supply infrastructure will have to be significantly expanded in order to meet growth expected by 2005. The need for new infrastructure will be particularly critical in meeting the growing demand for peak electric supply. The region will need to add 970 MW of peak electric power to balance demand and supply, and there are currently no identified sources for the power. Existing Conditions The capacity of the region's energy supply infrastructure will have to be sig- nificantly expanded in order to meet growth expected by 2005. The need for new infrastructure will be particularly critical in meeting the growing demand for peak electric supply (highest instantaneous demand for electricity, usually on a hot summer afternoon). 9 2005 Conditions The region will need to add 970 MW of unplanned peak electric power before 2005 to balance demand and supply. There are currently no plans for or ex- pected sources for this power. The region will have to initiate efforts to secure it. This is equivalent to about twice the power the San Diego region receives from the San Onofre nuclear power plant complex at Camp Pendle- ton. Energy demand is projected by SDG&E and the California Energy Com- mission (CEC) to grow at a much higher rate than population due to expected increases in per capita income, and strong employment growth. Between now and 2005 the region (SDG&E, local business, and homeowners) are expected to install the following additional peak electric capacity: 420 megawatts (MW) resulting from conservation 250 MW of peak electric generation capacity It is also expected that SDG&E contracts for out-of-area electric capacity will have declined by 500 MW. The net result of these forecast changes will be the need for an additional 970 MW of unplanned peak electric power as mentioned above. CEC forecasts show demand starting to exceed existing and planned peak electric capacity in 1993. The CEC suggests that the most likely sources of additional peak capacity are cogeneration and other independent power tech- nologies, and additional out-of-area purchases of peak power by SDG&E. This raises some concerns about the future availability of electricity: o Current electricity rate and regulatory trends toward "cost of service" rates tend to discourage independent power production and conservation, the most cost-effective supply sources, and in recent years, the major sources of new energy supply within the region. o The generally high growth rate in the Southwest, and environmental and economic concerns related to new power plant construction make the purchase of large amounts of peak power from areas outside the region uncertain. High growth rates are expected in other areas of the South- west and in Mexico. Competition for power purchases will increase among western utilities, as reflected in the projected SDG&E power purchase contract losses described above. An additional concern is the increasing level of reliance on oil and gas-fired electricity supply in the region. For example, SDG&E is expected to increase oil and gas-fired electricity generation by 4 billion kilowatt hours between 1990 and 2000, in order to keep up with total electricity demand. While worldwide physical supplies of oil and gas are projected to be adequate to meet needs in 2005, political and economic uncertainties related to their production give rise to concerns about relying on these source technologies. 10 Alternatives/Mitigations An ongoing, cooperative effort involving SDG&E, public agencies, and private industry and business is needed to develop a strategy for the San Diego region's unique energy problems. This strategy should focus on energy pricing and financing - the main barriers to utility and independent private and public action which could meet the region's future energy needs. The recommen- dations of the SANDAG Energy Finance Advisory Committee provide a basis for organizing such an effort. 11 1 I -1 - STAFF REPORT DATE: MAY 18, 1988 To: PLANNING COMMISSION FROH: PLANNING DEPARTMENT SUWECT: c0w)IENTs ON SANMG DRAFT REGIONAL GROWTH HANAGE"T RECOM"MTI0NS It is recommended that the Planning Commission accept the SANDAG report on Regional Growth Management Recommendations and forward staff's comments and any additional Planning Commission comments to the City Council. DISCUS SION On February 26, 1988 the SANDAG Board of Directors authorized distribution to member agencies of the Draft Regional Growth Management Recommendations for review and discussion. The SANDAG report is attached and it contains five Yecommendations as follows: 1. 2. 3. 4. 5. Adopt the Series VI1 Population Forecast (to the year 2010) and the first five years (1989-1994) of the Series Seven Housing Unit Forecast as policies for building permit activity by each jurisdiction. Enact (in its final form) the IISensitive Lands Initiative" currently being imposed in the City of San Diego and unincorporated areas of the county, as a coordinated and consistent policy for preserving sensitive and natural resource lands in all jurisdictions. Authorize development of new coordinated policies for financing regional serving public facilities and resources. Authorize development of a regional strategy to promote a better balance of population with employment opportunities in the regions communities. Authorize a comprehensive regional growth monitoring and annual reporting system that would address: regional resource quality and availability, and growth impacts upon the San Diego region. Recommendations 3, 4 and 5 involve authorization from the SANDAG Board to do additional .work in studying regional programs and strategies and therefore do not involve policy decisions at this time. Regarding recommendations 1 and 2, SANDAG is requesting that all member jurisdictions accept these as policies to better manage and coordinate growth on a regional basis. It is staff's belief that the overall goal of coordinating the management of growth throughout San Diego County is needed and, as such, Recommendations 1 and 2 are a positive initial step in that direction. Recommendation 1 would use the housing unit forecast as identified in the Series 7 Population Forecasts for the next five years as policy for a jurisdiction's share of building permit activity. For Carlsbad, this would equate to 6,438 dwelling units or an average of 1,288 dwelling units annually. There would be no penalty or sanctions if the share was not met or exceeded. Although Carlsbad uses yearly dwelling unit projections in our Growth Management Program, the objective of our program is to equate the amount of growth to the need for public facilities. As a result, the City has adopted a strict Growth Management Program which contains specific facility performance standards which must be maintained at all times in order to allow growth to occur. The recommendations being made by SANDAG do not address the impacts of growth, but only the number of residential units being built by each jurisdiction. In terms of this recommendation's effect on Carlsbad's program, it will have none other than just formally confirming the dwelling unit projections that staff already uses as a planning tool. There are however numerous cities in the county which do not have specific growth management programs and this could be a first effort in getting their cooperation in Regional Growth Management. Staff would recommend that the City make a recommendation to the SANDAG Board of Directors that the next step in this process might be for communities to agree on specific public facility performance standards which all jurisdictions must adhere to. As a starting point staff would recommend the acceptance of a transportation standard or a circulation standard similar to the one adopted in the City's Growth Management Program.

In their action, the Board clarified the staff recommendation to emphasize that the Growth Management Recommendations were being distributed for "review and discussion" at this time, and that staff would return to the Board in June 1988 with local reaction and, hopefully, a consensus on the Rcconrrncndationa. The Board also agreed that staff should initiate a round of meetinga with the member jurisdictions and other interested parties to discuss the Recommendations. The Board further directed that staff continue to analyze the application and impacts of policies designed to limit the future size of the region so that those option8 would be more clearly understood if a point in time were reached when these types of growth controls were being actively considered. SANDAG would appreciate your review of these recommendations and encourage your comments.

Those ordinances and policies adopted by the City Council actually appear to exceed the requirements of the sensitive lands initiative. Staff is recommending that the City Council urge other cities to adopt similar policies to the City of Carlsbad or that of the sensitive lands initiative. Draft Regional Growth Management Recommendations arb Vi Association of Gwmments BOARD OF DIRECTORS February 26,1988 AGENDA REPORT No,: R-17b DRAFT REGIONAL GROWTH MANAGEMENT RECOMMENDATIONS Introduction This report introduces a set of draft regional growth management recommenda- tions. These proposals are the result of the staff's analysis of growth management issues and options, and its participation with the member jurisdictions on their growth programs since February 1987. The recommendations are intended to provide a cooperative public policy framework so that local growth management plans and policies can be coordinated effectively to the benefit of each city, the County, and the region. They also are an attempt to develop a consensus on growth management policy among local jurisdictions, community leaders, and the public (as reflected in public opinion surveys). The basic objective of the recommendations is to facilitate wise management of the region's growth so that people's needs are met, quality public facilities are available for their use, and the region's rich envir- onmental resources are permanently protected. The recommendations rely in part on results of analyses conducted on the "carrying capacity" of the region as represented by six regional commodities, resources or types of infrastructure. Shortages or degradation of several resources or facilities currently exist, or will beyond the year 2000. These problems could alter or in- fluence the region's growth rate over either the short or long term. The analysis presents a set of findings on these effects and how these conclusions lead to new growth management policies. "Carrying capacity" is evaluated for (1) water avail- ability; (2) sewerage capacity; (3) solid waste disposal capacity; (4) air quality; (5) transportation system adequacy; and (6) energy availability. The resultant findings support the conclusion that new growth management policies should be considered. The report concludes with an expanded discussion of the draft growth management recommendations. The recommendations are: 1. Adopt the Series 7 population forecasts (to 2010) and the first five years (1989- 1994) of the Series 7 housing unit forecasts as policies for building permit activity by each jurisdiction. 2. Enact (in its final form) the "Sensitive Lands Initiative" currently being pro- posed in the City of San Diego and the unincorporated area of the County, as a coordinated and consistent policy for preserving sensitive and natural resource lands in all jurisdictions. 3. Authorize development of new coordinated policies for financing region- serving public facilities and resources. c 4. Authorize development of a regional strategy to promote a better balance of papulation with employment opportunities in the region's communities. 5, Authorize a comprehensive regional growth monitoring and annual reporting system that would address: regional resource quality and availability, and growth's impacts on the San Diego region. It is my RECOMMEND ATION that, based on the findings relative to the carrying capacity in the San Diego region and the considerable public interest in regional growth management, the Board of Directors of the San Diego Association of Governments accept this report on Draft Regional Growth Management Recommendations for distribution to (1) the local jurisdictions for review and consideration for adoption; and (2) the City of San Diego's Citizens' Advisory Committee on Growth and Development and the County of San Diego's Regional Growth and Planning Review Task Force for review and consideration for recommendation to their respective governing bodies. The staff should also schedule briefings with member jurisdiction councils and the Board of Supervisors on these findings and recommendations. Discussion This report on the carrying capacities and draft growth management recommen- dations for the region is based on a year's work in SANDAG's cooperative growth management evaluation project with the County and City of San Diego. The County's Regional Growth and Planning Review Task Force and the City's Citizens' Advisory Committee on Growth and Development will present growth policy rec- ommendations relative to existing plans and policies to the Board of Supervisors and City Council in late Spring. SANDAG's efforts in assisting these groups and other interested jurisdictions in the region include conducting public opinion surveys on attitudes toward growth; evaluating the costs of regional infrastructure and other public facility implications of future growth; identifying and analyzing the impor- tant external and internal factors which cause the region to grow; coordinating and monitoring growth management strategies and activities among the region's 19 jurisdictions; and examining possible methods for financing regional public facilities and resources. In addition, this report provides the basis and demonstrates the need for develop- ment of short-term growth management policies to allow workable planning and management of the growth that will inevitably come to the region. Development of new public policy recommendations to help manage and finance long-term growth is included as well as the long term, continuous monitoring of the region's growth. Monitoring the growth of Southern California and Baja California will enable the region to determine when its share of those regional resources and commodities might be constrained, and to respond appropriately. The following is a summary of the analysis of the carrying capacities for the six categories listed above: 2 .. 1. ' 2. 3. 4. 5. 6. WATER AVAILABILITY Areas of Southern California receiving their primary water supplies from the Metropolitan Water District (MWD) and the San Diego County Water Authority (CWA) could experience shortages between now and 2000, and beyond, partic- ularly if California and the Colorado River basin have periods of below average precipitation during those years. SEWERAGE CAPACITY The North County has current sewage capacity to accommodate growth until about 2005. The San Diego Metro System, however, requires an expansion of its treatment capacities now as it is converted to a secondary level of treat- ment to accommodate growth. SOLID WASTE DISPOSAL CAPACITY Solid waste disposal capacity will be exceeded in the next ten years unless major new facilities are successfully sited and recycling programs initiated in the region's urban areas. AIR QUALITY Although the region's air quality has improved, the San Diego air basin is not currently in compliance with federal standards for air quality. TRANSPORTATION SYSTEM ADEQUACY The recent grow'th in automobile travel has had a significant impact on the region's freeway system. Projects proposed over the next 19 years will main- tain mobility in the region by providing additional transit and highway facilities in the most heavily congested corridors. Transit access in 2005 will be signifi- cantly better than it is today; highway access, however, will be somewhat worse. The region's airport system will be at its capacity in 2005, and major new facilities will be required if growth beyond that time is to be accom- mod at ed. ENERGY The region's energy supply infrastructure will have to be significantly expanded in order to meet growth expected by 2005. The need for new infrastructure will be particularly critical in meeting the growing demand for peak electric supply. The region will need to add 970 MW of peak electric power to balance demand and supply, and there are currently no identified sources for the power. CONCLUSION It is clear that regional resources and the region's ability to accommodate growth will be impacted by strains placed on those resources by projected growth. Shortages or constraints will occur in several major regional resource areas including transportation, water availability, and peak energy supply. Furthermore, the costs of providing necessary facilities for solid waste and sewage disposal are high. Attaining federal air quality standards and maintaining those standards will be costly and will require changes in travel behavior of the region's residents. Shortages of regional commodities such as power and water would affect the ulti- mate size of the region; transportation system congestion or continued air quality problemr probably would not. But for the reasons stated and the concerns evi- denced by growth management actions of many of the jurisdictions in the region and the concern over growth demonstrated by public surveys and current citizens initiatives, new growth management policies on a regional level should be con- sidered. These recommendations do not call for actions to arbitrarily reduce the region's future population growth. The actions would, however, assure accommodation of forecast growth at a historically manageable rate for the next five years. This rate would be less than that of the rapid growth period since 1983. Simultaneously, SANDAG and local governments should cooperate to monitor regional and local growth and its environmental and economic impacts. It is pos- sible that within the next ten years new findings on regional carrying capacity will cause a reevaluation of a strategy of accommodating growth at a manageable rate, and consideration of policies to reduce the region's long-term growth rate will be necessary. This is not the case at the current time, however. The following section of this report describes a set of draft growth management recommendations which could be utilized by the region's jurisdictions as elements of a cooperative regional growth management strategy. ACTION 1 EACH JURISDICTION SHOULD ADOPT: (a) THE SERIES 7 POPULATXON FORE- CASTS (TO ZOlO), AND THE NEXT FIVE YEARS (1989-1994) OF THE SERIES 7 HOUSXNG UNIT FORECASTS AS POLICIES FOR BUILDING PERMIT ACTMTY. Why Undertake This Action? The need to establish a consensus on a manageable rate of regional growth, and how the region's jurisdictions would share that growth, has emerged as a primary issue at the regional level. The region's growth rate from 1983-87 (an average of 61,000 persons per year/about 3.1%) has taxed the ability of governmental agencies to meet environmental and facility provision demands, accelerated crowding of public and private facilities, and generated growth management policy actions by 13 of the region's 19 general purpose agencies in response to public interest in "doing something about rapid growth." The Regional Growth Forecasts represent the amount of growth the region is likely to have, based on a combination of local, state, and national demographic and economic trends. Since 1972 the Forecasts have accurately predicted the region's total growth. An average year of these forecasts represents a growth rate that public and private entities have traditionally been able to deal with; and one in which environmental and economic safeguards need not be exceeded. By adopting the dwelling unit totals developed in the Forecasts, for a five year period, and using these as public policies to guide building permit activity, cities and the County accommodate a normal share of future regional growth, but at a rate that avoids adverse economic and environmental impacts and does not impose artificial caps on local housing development. There are other reasons to take this action: 4 The action represents a timely, coordinated, and pro-active response by the local jurisdictions to growth pressures, It enables clear understanding of the interjurisdictional impacts of each corn- munity's growth and forecloses the necessity to consider defensive local ordi- nances. It gives local agencies the flexibility to take advantage of the housing market and market condition changes over a fiveyear period. ' It demonstrates that local jurisdictions are accepting a share of regional growth based on a cooperatively prepared forecast. Consequently, the action should help local agencies avoid growth-related litigation. The action enables cities and the County to accurately forecast the five-year need for public facilities and to better phase the financing and development of facilities. The action avoids artificial caps on local housing development. SANDAG research has shown that individual jurisdiction housing caps have no effect on regional growth, tend to cause a local disproportion of employment and housing mix unless coupled with job reductions, and have adverse social impacts by limiting availability of new and used housing. Limiting housing availabililty drives up prices and rents, and those increases are felt disproportionately across the population. The action provides jurisdictions with a tool to coordinate building permit activity with local general and community plans, and to integrate public facilities and other improvements. How the Action Could Be Implemented Each jurisdiction would adopt a total number of dwelling units for the five-year period from 1989-1994 based on the Series 7 Forecasts for those years. The Fore- casts, which predict occupied housing, would be adjusted upward for vacancy rates. Table 1 includes 1987 data for each jurisdiction and housing completion and authorization data for 1986, a year of very rapid population growth. The table also shows the 1989-94 dwelling unit totals from preliminary Series 7 and the five year and annual activity allocations which the jurisdictions would be asked to consider. Table 4 describes recent, historic, and forecast growth of housing. 5 0 X f= El - 31 -1 a s TABLE 2 INCREASE IN HOUSING SUPPLY SAN DIEGO REGION 1970-2010 Series 7 Total' Total2 Total' * Average Average Average Dwelling Dwelling Dwelling Annual Annual Annual Units Units Units Change Change Change - 1970 - 1984 - 1987 1970-87 1984-87 1986-20 10 450,798 763,085 855,545 24,164 30,820 19,546 1. U.S. Census, 4/1/70 2. Estimated 1/1/84 and 1/1/87 Each jurisdiction would be responsible for allocating the total units throughout the five-year time period as demand or public policy dictates. This gives the oppor- tunity to let the private market adjust to interest rate and market cycles. It is also useful for predominantly developed communities that have large new projects or major redevelopment projects only every few years. The annual averages, which are based on General and Community Plans, indicate about how much housing constitutes a jurisdiction's share of anticipated five-year growth and its housing needs. They are by no means, however, performance standards that need to be met in any one year. ACTION 2 ENACT (IN ITS FINAL FORM) THE "SENSITIVE LANDS INITIATIVE" CURRENTLY BEING PROPOSED IN THE CITY OF SAN DIEGO AND THE UNINCORPORATED AREA OF THE COUNTY, AS A COORDINATED AND CONSISTENT POLICY FOR PRESERVING SENSITIVE AND NATURAL RESOURCE LANDS. Why Undertake This Action? Behind transportation problems, the public perceives the change in the region's face as the most disagreeable impact of rapid growth. Develoment of slopes and flood- plains, lobs of sensitive lands, excessive grading, habitat clearing, and view encroachment are mentioned most often as adverse impacts. Every jurisdiction has requirements for dedication of related open space concurrent with development, ad many have overlay zones or other regulations to protect specific resource areas. However, coordinated and consistent policies on a regionwide basis would more effectively respond to the public's concern. Enactment of a common final version of the Sensitive Lands Initiative by all 19 jurisdictions would have several distinct advantages. o The action would create consistent local policies for dealing with open space and sensitive lands, which would be valuable to both public agencies and the development community. 7 The action uses as a model a document designed by a citizens group in response to strongly held citizen opinion. Consistent sensitive lands policies enable local agencies to plan more effec- tively for important river corridors and other contiguous open space areas which cross jurisdictional boundaries. Cooperative plans such as the one cur- rently being prepared for the San Dieguito Valley would be much easier to prepare and implement, Coordinated policies to protect habitat, wetlands, and other threatened resource areas will help resolve conflicts between proposed public improve- ments and endangered species and habitat loss regulations of state and federal agencies. The action would preserve irreplaceable resources which are important contri- butions to the region's quality of life. Additionally, implementation of conser- vation policies can focus public and private sector resources on sensitive lands in ways which benefit all involved parties. How the Action Would be Implemented The Sensitive Lands Initiative petition is currently being circulated by an environ- mental interest group called San Diegans for Managed Growth. The group's current intention is to place the Initiative on the ballot in November 1988 in San Diego and the unincorporated area of the County, A synopsis of the Initiative follows this section. It is not currently known whether or not the initiative process will be pursued in the other cities, if some jurisdictions will choose to enact the Initiative through local ordinance, or if the Initiative will be modified as a result of nego- tiation between the proponents and local governments. In any case, the Initiative is a reasonable basis for a coordinated regional policy and in its final form the cities and County would benefit from uniformly enacting it. In response to enactment, SANDAG would undertake a project as part of the Re- gional Open Space Plan to cooperate with the jurisdictions to identify and map lands subject to the initiative, resolve any definitional or resource questions, and monitor the sensitive lands resource regionally. Summary of Sensitive Lands Initiative This initiative is currently being circulated in both the City of San Diego and un- incorporated portions of the County to qualify for the November ballot. The specifics of these two initiatives are: o Creation of a Resource Conservation Overlay Zone based on an inventory of all sensitive lands including, at a minimum, wetlands, floodplains, steep hillsides and canyon slopes, critical habitats, areas of native vegetation, and significant archaeological or historical sites. o Specific regulations/permits for any activity within this Overlay Zone, with the following permitted uses for each category. 8 Wetlands - aquaculture, scientific, educational or recreational uses if not harmful to the ecovtem; restoration projects; essential public service project8 or water-depedent public facilities if no viable alternatives exist, with mitigation measures resulting in a net gain in functional wetlands; . Wetland Buffers - access paths, improvements necessary to protect adjacent wetland8 and/or health, safety and general welfare; Floodplains - agriculture, low intensity recreational uses; grading and filling of floodplains in public ownership for essential public facilities if no viable alter- natives exist providing mitigation results in a net gain in functional wetlands and riparian habitat; no permanent structures, fill or grading for purposes other than habitat restoration will be allowed. Steep Slopes - one residential unit per .96 acre (40,000 square feet) on 25% slopes; one unit per 10 acres on 50%+ slopes; limits encroachments on sliding scale based on steepness of slope for specific public projects if no viable alter- natives exist, based upon public hearing and finding by Planning Director that such encroachment is consistent with intent and purposes of this Initiative, ACTION 3 AUTHORIZE DEVELOPMENT OF NEW COORDINATED POLICES FOR FINAN- CING REGION-SERVING PUBLIC FACILITIES AND RESOURCES. Why Undertake This Action? At this meeting the Board of Directors will begin discussing financing some selected categories of public facilities and desirable public resources at the regional level. The companion report points out that there are several types of facilities which are provided regionally and could potentially be financed all or in part, more effectively through a regional source. These public facilities could include sewage treatment, transportation, courts and jails, solid waste manage- ment, public schools, and others; development and acquisition of regional resources such as open space or low income housing could also be financed at the regional level. The Board is requested to authorize staff to complete a feasibility analysis of regional financing and develop draft policies during FY 1988-89 as a part of the Overall Work Program (OWP). The policies would have to address: o Identification of facility financing options equitable to new and existing resi- dents. o Lack of money for both capital and operating costs. o Financing open space acquisition. o Pooling the agencies' ability to finance needed improvements. o Encourage pubIic/private partnership and innovation in developing regional facilities. 9 ACTION 4 AUTHORIZE DEVELOPMENT OF A REGIONAL STRATEGY TO PROMOTE A BETTER BALANCE OF POPULATION WITH EMPLOYMENT OPPORTUNITIES IN THE REGION'S COMMUNITIES. Why Undertake This Action? Since the adoption of the first Regional Transportation Plan in 1974, the concept of economically balanced communities has been considered an important way to mitigate adverse impacts of population growth. Recent research has also cor- roborated the dominant role that employment and job creation have in regional growth. The Series 7 forecasts show that the character of work trips in the region is changing as residential development and employment centers grow farther apart. The San Dieguito River crosses 1-5 in north Del Mar and 1-15 at Lake Hodges. If an imaginary line were drawn between these two points, one out of every four people living north of the line commute south of it to their place of employment; in 1985, about 83,500 daily trips on the two freeways. By 2010, this ratio becomes slightly larger and the actual number of trips increases to 164,500 per day. This increase in the number and length of work trips has obvious implications for air quality and energy consumption as well as freeway congestion. Better economic balance of communities would positively address this growing problem but should also address other existing problems including uncoordinated and potentially un- productive expenditure of local money on. industrial land development and an over- abundance of industrially zoned land in certain parts of the region. On this last point, Series 7 shows that over the next 25 years the region can expect to develop about 350 industrial acres per year. In 2010, however, an inventory of 10,500 industrial acres remains vacant and unused. As with Action 3, the Board is requested to authorize a job as part of the OWP that will focus on drafting a set of coordinated actions which local jurisdictions could take to improve the ability of residents to live and work in the same community. The job will also develop a methodology to better balance economic development and industrial land creation with housing growth. ACTION 5 AUTHORIZE A COMPREHENSIVE REGIONAL GROWTH MONITORING AND ANNUAL REPORTING SYSTEM THAT WOULD ADDRESS: REGIONAL RE- SOURCE QUALXTY AND AVAILABILITY; AND GROWTH'S IMPACTS ON THE SAN DIEGO REGION. Why Undertake This Action? If the region's jurisdictions decide to adopt policies to cooperatively manage future growth, an annual monitoring and reporting system will be necessary. Regular reporting to the Board of Directors would enable the jurisdictions to actively monitor changes in the growth rate, economic and demographic trends, and both interjurisdictional and extra-regional impacts of growth. Successful management of the region's future growth requires a balance of policies which simultaneously 10 control some activites related to growth while encouraging others. Economic, environment& social, and other impacts may be either negative or positive and only regular monitoring and reporting allows elected officials to be aware of these trendn ad amurea the public that growth management issues are being actively addremed. The Board's action on this item is to authorize inclusion of the monitoring process as an expansion to the FY89 OWP. The r;egional growth management monitoring and reporting process would evaluate two distinct areas of interest and concern on at least an aanual basis: Regional Resource Quality and Availability - - - - - Annual monitoring of energy and water availability Continued rnonitoring/forecasting of air quality standards attainment Annual updating of regional infrastructure cost and regional ability to Pay Reservation/development of open space and sensitive lands. Growth of the five Southern California counties and Tijuana compared to regional resource quality and availability Growth of the San Diego Region - Dwelling unit approval/development consistency with Series 7 (moni- toring of Action 1) - Commercial and industrial floor space approval/development as a measure of job creation - Changes in employment and housing ratios in the region's subareas - Impacts of growth m'anagement policies - Regular evaluation of the Regional Growth Forecasts. ACTIONS NOT RECOMMENDED FOR 1988 In the process of studying regional growth and its potential for effective manage- ment, the County, cities and SANDAG have identified a number of possible strat- egies which are not recommended for action. It may be necessary to review these or other actions in the future, as is discussed in the section of this report on carrying capacities, if it becomes clear that it is necessary to reduce the ultimate population of the region. The need is not clear at the current time. o Housing Caps Are Not Recommended Housing caps which are intended to reduce the ultimate size of the region's population are directed at a symptom of growth rather than a cause. In addi- tion to the adverse housing supply, cost, and unequal economic impacts already discussed, the long-term effects of artificial housing caps on other social and economic factors of the region are poorly understood. Additionally, housing caps need to be extremely restrictive if they are to have a noticeable impact. In the "Causes of Growth" report released by SANDAG in September 1987, it was shown that using residential supply controls alone in order to slow growth to a rate similar to that of California (about 34,300 persons per year), new housing would have to be limited to 5,000 units per year. Series 7 forecasts that an average of about 20,400 units will be built each year between 1985 and 11 "(- 2010. Of these homes, 5,900 units per year will be needed to house the off- spring of the 2.4 million people already here and would be required if no new migrants entered the region over the next twenty-five years. o Employment Development Restrictions Are Not Recommended If reduction of the future size in the growth rate became necessary, restric- tions on employment development would be the single most effective means to achieve this. The "Causes of Growth" report showed that 60% of the region's population growth is directly attributable to in-migration associated with the creation of new jobs. Creation of jobs is, however, the result of a robust economy and in the public opinion survey and subsequent discussions with community leaders, there was no interest in job growth restrictions in the region or in limits on commercial and industrial floor space. Perhaps most importantly, the positive or negative impacts of this type of economic manipulation are not well understood. Data are not readily available on the amount of employment growth needed to assure a viable regional economy, and how job reductions cut across social and economic components of the community are not known. POTENTIAL COMPLEMENTARY ACTIONS Other growth management strategies were suggested that could be reviewed at a future date and which could complement the recommended set of cooperative regional actions. They include: o Coordination of local development and infrastructure financing fees among the general purpose agencies. o Similar coordination of the process and procedures to modify general and community plans. o Continuation of the process to develop and adopt consistent regional policies on urban development which occurs on the periphery of existing cities, and on develop ment of new non-c on tiguous communities. o Development of a process for coordinating growth and impacts research among the five Southern California counties. -w KENNETH E. SULZER Executive Director 12 ATTACHMENT 1 This attachment provides additional detail to the carrying capacity analysis included in the discussion section of this report. 1. WATER AVAILABILITY Areas of southern California receiving their primary water supplies from the Metropolitan Water District (MWD) and the San Diego County Water Authority (CWA) could experience shortages between now and 2000, and beyond, partic- ularly if California and the Colorado River basin have periods of below average precipitation during those years. Data published by both Metropolitan and the Authority support this conclusion. Existing Conditions The CWA and MWD are independent agencies, and although the Authority receives almost all of its water from the larger provider, the two organizations prepare independent forecasts of water availability in their respective service areas. Interpolation of the data contained in Table 1 for 2005 shows a poten- tial shortage of 770,000 acre feet, 19% of MWD's forecast demand. This amount of water would serve a population of 3,500,000. Table 2, derived from data provided by CWA, quantifies this region's shallow water resources, showing the San Diego region's demands roughly equal to available supplies.

It is unusual, though not unheard of in this country, for a large metropolitan area to have this much uncertainty about its existing and future water supply. The root cause of the uncertainty, of course, is the area's need to import most of its supply. At our current rate of use, if we had to live on our own water production, the area could accommodate only about 150,000 people. Furthermore, CWA's projec- tions of demand presented in Table 2 are predicated on maintaining our water use at the current level of .22 acre feet per person per year. In fact, our per capita water use has been increasing generally since 1959, and has gone up in each of the past four years. Maintaining a use level of .22 through 2005 pre- sumes that people will improve their water conservation practices almost immediately and that many will change their home and business landscaping. The San Diego region is, naturally, a coastal desert. Southern Californians traditionally have ignored water issues, preferring to leave them to the "water people." Obviously, the "water people" at agencies such as MWD and CWA have done a good job: the water has always been there when we turn on the tap. However, we would be making a mistake merely to assume that alternative sources of supply will necessarily be available to make up for future shortages in imported water. The water supply agencies need support now both locally and in Sacramento. AlternativeslMitigation At the local level, water conservation can be increased to help mitigate short- ages. Approximately one-half of the region's municipal/industrial water is used for outdoor activities, such as landscape maintenance. Use of xeriscaping, native or drought-resistant plants, is the most effective method of reducing outdoor water use. Local jurisdictions will eventually mandate the use of 2 drought-tolerant plants in new landscaping. Drought tolerant landscaping can be ab attractive and functional as high water using vegetation. Wastewrtct reclamation could produce a significant "new" supply, and the region ahdd increase its use as a substitute for imported water wherever possible. Reclamation might ultimately be mandated for certain uses, partic- ularly outdoor irrigation of large areas. An ongoing, cooperative effort involving the League of California Cities, the County Supervisors Association of California, the California Councils of Gov- ernments, the Southern California Water Committee, and others is needed to develop consensus on water policy which would be recognized by the State Administration and the Legislature as the direction water management should take. Following that consensus, water development and management programs are needed. 2. SEWERAGE CAPACITY The North County has current sewage capacity to accommodate growth until about 2005. The San Diego Metro System, however, requires an expansion of its treatment capacity now to accommodate growth as it is converted to provide a secondary level of treatment. Existing Conditions Sewage collection and treatment service is provided by 38 different agencies throughout the urbanized areas of the region. Historically, additional service agencies have been created as the need arises. The largest agency is the San Diego Metropolitan Sewerage System (Metro) which currently serves more than seventy percent of the region's population through 15 member agencies. The Metro system operates the region's largest sewage treatment plant, located at Point Loma. Current daily flows at the plant are about 165 million gallons per day (mgd). Metro was designed to ultimately treat 234 mgd but has installed facilities to treat only about 120 mgd. Metro's discharge permit allows the additional flow to be treated as long as ocean water quality standards are met and other specific steps are taken. Metro's current National Pollutant Dis- charge Elimination System (NPDES) permit issued by the Regional Water Quality Control Board in March 1985 expires in 1988, when new federal dis- charge requirements will be in effect. The City of San Diego is currently involved in the planning and design of new treatment facilities that would accommodate both the projected need and the federal and state water quality standards. Three other agencies operate treatment plants with ocean outfalls: Oceanside, Encim and San Elijo. They have a combined capacity of 69 mgd. Together, the four facilities have a current design capacity of approximately 303 mgd, and serve some 93% of the region's households. Flows in 1986 were 207 mgd. New federal water quality standards require secondary treament and all four outfalls have committed to making this expensive conversion. Encina has already installed secondary treatment and both Oceanside and San Elijo can accommodate the additional facilities at their existing sites. Metro, however, cannot and will be required to construct a new planth) at a separate siteb). 3 2005 Conditions By 2005 the four systems will be required to provide total treatment capacity 'of 273 mgd; 199 mgd at Metro. Upgrading to secondary treatment will allow the rather small (5 mgd) additional capacity needed by the North County plants to be developed. Metro, however, intends to expand to 240 mgd of actual capacity at one or more sites. The 314 mgd of total capacity would serve the region well beyond 2005; however, development of time consuming and costly facilities must be sited and financed before this excess capacity will be a reality. Alternatives/MitiRation Partial mitigation for the high costs involved in providing a new treatment plant could be utilization of the higher quality effluent for reclamation or reuse, thereby providing an additional source of water to the region. Aqua- culture is another alternative method that could eventually lead to water recycling. 3. SOLID WASTE DISPOSAL CAPACITY Solid waste disposal capacity will be exceeded in the next ten years unless major new facilities are successfully sited and recycling programs initiated in the San Diego region. Existing Conditions The City and County of San Diego are the two agencies responsible for solid waste disposal facilities in the region. The County owns five sanitary landfills which are operated by private contractors. It has approved the construction of a solid waste recovery plant at the San Marcos landfill which could be in opera- tion as early as 1990. The City of San Diego owns and operates two landfills. Current capacity at the landfills is about 56 million tons. Both the City and County of San Diego recognize that annual solid waste generation rates, currently 1.49 tons per capita are expected to increase to 1.77 tons per capita by 2005. If this forecast is accurate, additional solid waste disposal capacity must be developed. In response, local governments are initiating aggressive recycling programs, searching for new landfill sites, and exploring alternative technologies for solid waste processing and disposal. These include waste to energy processes and new recycling materials and markets based on currently unrecyclable components of the waste stream. 2005 Conditions New solid waste disposal facilities and recycling programs will be needed before 2005 to provide capacity for the region. Capacity will run short in the late 1990's if no new actions are taken. Implementation of the San Marcos landfill resource recovery project and approved local government recycling programs should extend capacity past the year 2000. However, based on current forecasts of waste generation, by 2010, additional new facilities and programs will be required. 4 AlternatiVtS/MitiRation Efforts are now underway in three are- to add the new solid waste disposal capacity that the region will need: o Implementation of extensive recycling programs (to reduce annual solid waste disposal needs by 20 to 30 percent); o Exploration of alternative solid waste processing ad disposal technol- ogies; o Search for new land fill siter. Development of sources of financing is a key isme for local governments in all three areas. Interjurisdictional cooperation, particularly in the financing of recycling programs, will also be an important requirement. 4. AIRQUALXTY Although the region's air quality has improved, the San Diego air basin is not currently in compliance with federal standards for air quality. Existing Conditions The Environmental Protection Agency (EPA) is expected to issue a policy by mid-1988 to continue implementation of the Act, requiring new state plans showing how each air basin will achieve the national ambient air quality stan- dards for ozone and carbon monoxide. The plans must demonstrate how the air basin will be in attainment by 1995, and haintain national air quality standards through 2005. Measures requiring an average annual reduction of 3 percent in emissions will be implemented until the national standards are met. In 1982, the region adopted four transportation strategies designed to reduce vehicle emissions and bring the region into attainment with the national air quality standards. Those strategies are: ridesharing, transit, bicycle travel, and traffic improvements. These four tactics were projected to reduce 1986 reactive hydrocarbon emissions by 2.129 tons per day and carbon monoxide emissions by 24.76 tons per day. However, in 1986, the actual reductions were 7 percent of the plan for reactive hydrocarbons and 9 percent of the plan for carbon monoxide. Since 1977, there has been a steady improvement in the region's air quality due mainly to control of fixed source emissions, cleaner fuels, and inspection and maintenance of pollution control devices on automobiles. For the period 1985- 1987, there were no violations of federal standards for carbon monoxide, nitrogen dioxide, or sulfur dioxide, although the state standard for nitrogen dioxide was exceeded once. In 1987, the region experienced 40 days during which ozone levels exceeded federal standards, 14 of which were attributable to local sources, and 26 which resulted from ozone transported from the South Coast (Los Angeles) air basin. Beginning in 1988, the San Diego air basin will have to begin reduction of pollu- tants to meet federal standards by 1995. In order to achieve this, not only will 5 existing transportation tactics to reduce pollutant levels need to be more effective, but new and stricter controls on auto use and emissions will have to be implemented. The measures to achieve the emission reductions will be developed in 1988-1989 and the adopted measures will be included in the 1990 State Plan and presented to EPA for approval. 2005 Conditions The San Diego air basin must meet federal air quality standards by 1995, and maintain that status thereafter. For those air basins not in attainment, EPA may well issue sanctions which could include inhibiting growth in the regions in which they are imposed. Sanctions authorized by the Clean Air Act include bans on construction of stationary emission sources and withholding grants for transportation projects and sewage treatment plants on the assumption that these may encourage growth. Restriction of participation in these programs would affect the region's ability to accommodate forecast growth. A number of measures may be implemented to assure attainment of federal air quality standards, some at the federal level, but most on the local level. For example, federal requirements may result in automobiles operating on alter- native fuels, while at the state level, vehicle inspection and maintenance may be required annually. In order to attain clean air standards, the State of California and the San Diego region will be required to adopt and implement measures to reduce emissions. As previously stated, reductions of 3 percent per year are required, after full mitigation of growth. If the San Diego region's emissions were to increase by 2 percent per year due to growth, the average annual reduction in pollutants would need to be 5 percent to meet and maintain EPA requirements. AI ternatives/Mitigation California currently has the strictest air quality standards and pollution control measures in the country. Various tactics or measures which would assist the region in attaining federal standards include (not necessarily in priority order): 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. voluntary no-drive days trip reduction ordinances employer-based transportation management (including tax incentives for employer programs) improved public transit parking management programs park and ride/fringe parking work schedule changes road pricing (tolls) traffic flow improvements rideshare incentives control of extended idling of vehicles gasoline fuel alternatives conversion of fleet vehicles to cleaner fuels or engines reduction of cold start emissions. 6 _- On the national level, enhanced programs for vehicle inspection and main- tenance and other emission control standards at stationary sources such = municipd kndfilb may be required. 5. TRANSPORTATION SYSTEM ADEQUACY The recent growth in automobile travel ha had a significant impact on the region's freeway system. Projects proposed over the next 19 years wilt main- tain mobility in the region by providing transit and highway facilities parallel to tho- which are expected to be most heavily congested. Transit access in 2005 will be significantly better than it is today; highway accesa will be some- what worse. The region's airport system will be at its capacity in 2005, and major new facilitier will be required if growth beyond that time is to be accommodated. Existing Conditions Freeways - During peak periods, significant portions of the region's freeway system are over capacity. For these routes, the population has exceeded the holding capacity of the freeway network, resulting in slower-thawoptimal speeds or transfer of trips to a less congested time. E8 in Mission Valley has been congested for years, while 1-5 north of Sorrento Valley and SR78, with a near doubling of traffic since 1980, have more recently become congested. Other portions of the system, such as the South Bay Freeway, 1-5 north of Encinitas Boulevard, and 1-15 north of Rancho Penasquitos, retain adequate capacity. Streets and Roads - The condition of local streets and roads is similar to that of the freeway system. Much of the local network is relatively free-flowing, even during the peak hours. However, many major streets, such as Friars and Mission Gorge Roads, have been congested for years. In general, the growth of travel on local streets and roads has been less than the growth on freeways in recent years. Funding shortages since the late 1970's have decreased the ability of cities to expand the local street system. Local jurisdictions report a backlog of a half billion dollars in local street maintenance and construction projects. Transit - With few exceptions, the region's transit system operates at less than capacity. The bus system, however, because it operates on the streets and freeways, is affected by the congestion of those facilities. Aviation - The region's airports have sufficient capacity to handle the existing demand, although some delay does occur during peak periods. However, one factor affecting the holding capacity is aviation-generated noise. With minor exceptions, the general aviation airports conform to state noise standards. Lindbergh Field, on the other hand, is operating under a noise waiver from the state. 2005 Conditions Congestion on the region's freeways and local streets will have increased significantly over existing conditions by the year 2005. In addition, general 7 aviation airports and Lindbergh Field's single runway will have reached capacity. Only the transit system, with the exception of local buses, will have adequate capacity to serve projected needs. Freewap - Even with the full implementation of the year 2005 freeway net- work adopted in the 1986 RTP, congestion on the region's freeway network will increase. The peak congestion periods will lengthen on most freeways in the urbanized areas. Heavy congestion is expected to spread to 1-5 in Sorrento Valley and in National City, and to 1-5 near Rancho Bernardo. The newer facilities - SR76, SR56, SR52 and SR125 - are projected to remove signifi- cant amounts of traffic from existing routes. Nevertheless, within the urban- ized area, nearly all of 1-5, 1-15, 1-8, 1-805, ad SR94 will be at least moder- ately congested. With the improvements proposed for SR78, conditions on that freeway are anticipated to be better in the year 2005 than they are today, Construction of SR52 and the Mission Valley Trolley extension, will prevent any significant deterioration of travel on 1-8, while congestion on SR94 will improve somewhat with the reconstruction of SR54 and the East Urban Trolley extension. Many areas are attempting to deal with congestion by changing commuting patterns. Carpools, staggered work hours, and incentives for utilizing transit are a few examples of strategies being used. The City of San Marcos has implemented an ordinance requiring employers to seek reduction of peak hour vehicle trips by their employees. The City of San Diego is currently studying similar regulations. During FY89, SANDAG will be developing a regionwide demand management program. This program will be developed in cooperation with its member agencies, and will build on the previous efforts of San Marcos, San Diego, the County, and the North County Traffic Demand Management Task Force. Streets and Roads - Congestion on local streets has not been documented in the same comprehensive manner that freeways have. As stated above, it is known that travel on freeways has been growing at a much faster rate than travel on streets and roads. However, it is expected that this trend will reverse as more of the freeway system reaches capacity. In developing the Proposition A program, each City and the County developed a program to accommodate the projected ZOOS population. Prop A, with other known revenue sources, will fund only 60% of this identified need. In view of projected growth and large funding shortfall, the rate of increase in congestion on the street and road network is anticipated to be worse than that on the freeway system. Transit - With the proposed expansion of the region's rail and bus system, adequate capacity should be available to accommodate year 2005 demand. The rail system and the 1-15 High Occupancy Vehicle lane will permit the transit system to avoid many major areas of congestion. However, local buses, which will carry a majority of the transit riders, must continue to operate on local streets and will be subject to significant delay during peak periods. Aviation - Planned expansion of existing airports should accommodate the anticipated demand through the year 2005. However, beyond that date, an 8 -. e additional general aviation airport will be needed and Lindbergh Field's single runway will be at capacity. Comprehearhe Laad Use Plans for the larger general aviation airports should enaura that noise impacts from these facilities will not increase. Depending on aircraft technology, noise impacts of Lindbergh Field may actually decrease, even with a significant growth in the number of flights. Alternatires/Mitigation The Regional Transportation Plan (RTP) proposes a balance of transportation improvements aimed at correcting existing system deficiencies ami accom- modating growth. The highway system improvements are planned to more directly connect employment centers to residential areas (SR52) or provide additional capacity at major points of congestion (the 1-5/I-805/SR56 inter- change). The transit system is designed to provide additional capacity in already congested corridors to both relieve existing demand and accommodate growth. However, it is unlikely that San Diego will ever return to the free-flow con- ditions which characterized the region in the recent past. Trends over the past few years indicate that car ownership and the length ad number of trips per resident are increasing more rapidly than the population. The RTP does not attempt to maintain the current level of automobile access. The facilities which would be needed to maintain these levels are simply beyond the financial resources of the region. The RTP does attempt to maintain personal mobility through the provision of transit services and through better management of existing and new transportation facilities. Traffic system management, including peak hour traffic management, and coordinated land use and transportation planning, hold the most promise for mitigating current and future traffic congestion. Land use regulation could decrease the need for new facilities. Employment growth in areas of significant congestion could be discouraged or prohibited. Employment could be encouraged in areas served by less congested freeways, and with good transit service. 6. ENERGY The region's energy supply infrastructure will have to be significantly expanded in order to meet growth expected by 2005. The need for new infrastructure will be particularly critical in meeting the grow- demand for peak electric supply. The region will need to add 970 MW of peak electric power to balance demand and supply, and there are currently no identified sources for the power. Existing Conditions The capacity of the region's energy supply infrastructure will have to be sig- nificantly expanded in order to meet growth expected by 2005. The need for new infrastructure will be particularly critical in meeting the growing demand for peak electric supply (highest instantaneous demand for electricity, usually on a hot summer afternoon). 9 2005 Conditions The region will need to add 970 MW of unplanned peak electric power before 2005 to balance demand and supply. There are currently no plans for or ex- pected sources for this power. The region will have to initiate efforts to secure it. This is equivalent to about twice the power the San Diego region receives from the San Onofre nuclear power plant complex at Camp Pendle- ton. Energy demand is projected by SDG&E ad the California Energy Com- mission (CEC) to grow at a much higher rate than population due to expected increases in per capita income, and strong employment growth. 4 Between now and 2005 the region (SDG&E, local business, and homeowners) are expected to install the following additional peak electric capacity: 420 megawatts (MW) resulting from conservation 250 MW of peak electric generation capacity It is also expected that SDG&E contracts for out-of-area electric capacity will have declined by 500 MW. The net result of these forecast changes will be the need for an additional 970 MW of unplanned peak electric power as mentioned above. CEC forecasts show demand starting to exceed existing and planned peak electric capacity in 1993. The CEC suggests that the most likely sources of additional peak capacity are cogeneration and other independent power tech- nologies, and additional out-of-area purchases of peak power by SDG&E. This raises sdme concerns about the future availability of electricity: o Current electricity rate and regulatory trends toward "cost of service" rates tend to discourage independent power production and conservation, the most cost-effective supply sources, and in recent years, the major sources of new energy supply within the region. o The generally high growth rate in the Southwest, and environmental and economic concerns related to new power plant construction make the purchase of large amounts of peak power from areas outside the region uncertain. High growth rates are expected in other areas of the South- west and in Mexico. Competition for power purchases will increase among western utilities, as reflected in the projected SDG&E power purchase contract losses described above. An additional concern is the increasing level of reliance on oil and gas-fired electricity supply in the region. For example, SDG&E is expected to increase oil and gas-fired electricity generation by 4 billion kilowatt hours between 1990 and 2000, in order to keep up with total electricity demand. While worldwide physical supplies of oil and gas are projected to be adequate to meet needs in 2005, political and economic uncertainties related to their production give rise to concerns about relying on these source technologies. 10 Alternatives/Mititzations An ongoing, cooperative effort involving SDG& E, public agencies, and private indu8trg .nd businesr is needed to develop a strategy for the San Diego region's unique Umrgg problems. This strategy should focus on energp pricing and financing - the main barriers to utility and independent private and public action which could meet the region's future energy needs. The recommen- dations of the SANDAG Energy Finance Advisory Committee provide a basis for organizing such an effort. 11
