HD. b’v’ MTG. &j+?--%f HILLSIDE ORDINANCE AMENDMENT CITY ATTY. ZCA 96-04lLCPA 96-01 iE DEPT. PLN W+ CITY MGR* RECOMMENDED ACTION: That the City Council INTRODUCE Ordinance No. AS- l/Y6 APPROVING Zone Code Amendment 96-04, ADOPT Resolution No. q 0 -‘IV APPROVING the Negative Declaration issued by the Planning Director, Zone Code Amendment 96-04 and Local Coastal Program Amendment 96-01. ITEM EXPLANATION: On January 7, 1998, the Planning Commission conducted a public hearing and unanimously (7-O) recommended approval of a Zone Code Amendment and Local Coastal Program Amendment to revise the City’s Hillside Development Ordinance and Uses Generally regulations (Chapters 21.95 and 21.53 of the Carlsbad Municipal Code) to: (1) streamline the Hillside Development Permit process, (2) clarify and reorganize the Hillside Development Ordinance to make it more user friendly and (3) revise or add development standards to address Ordinance issue areas. The major revisions to the Hillside Development Ordinance include the following: 1. 2. 3. 4. 5. Exempt: a) the development of a single family residence on a residential lot and b) the additional development of manufactured slopes on a single lot from having to process a Hillside Development Permit. These exemptions would still be required to comply with the Hillside Development and Design Standards and would be evaluated for compliance during grading plan/building plan review. Allow for the limited development of manufactured slopes subject to new manufactured slope development standards. Establish a new slope edge building setback standard to encourage the development of multiple storied buildings that step away from a downhill slope. Require the contour grading of all manufactured slopes that are greater than 20 feet in height and 200 feet in length which are located adjacent to or are substantially visible from major roads or useable public open space areas. The existing standard requires manufactured slopes which are greater than 30 feet in height or 200 feet in length to be contour graded. Allow manufactured slopes to be developed to a maximum height of 40 feet for the purpose of providing more open space separation between residential structures which are terraced along a hillside. The existing standard limits manufactured slopes to a maximum height of 30 feet. PAGE 2 OF AGENDZILL NO. /q, 4/n 3 6. Allow for limited development of natural slopes with gradients of greater than 40% by defining an undevelopable natural slope as having all of the following characteristics; (a) a gradient of greater than 40%, (b) an elevation differential of greater than 15 feet, (c) a minimum area of 10,000 square feet and (d) the slope comprises a prominent land form feature. 7. Similar to Circulation Element Roads, exempt collector streets from the development standards of the Hillside Ordinance. Over the past year, Planning staff has had ongoing meetings with the local development community (including the Building Industry Association of San Diego County) to receive critical input and comment on the draft amended Hillside Development Ordinance. As a consequence, the draft Ordinance has been revised to achieve a Hillside Ordinance that is streamlined, user friendly, and continues to focus on the protection of hillside resources within the City. Four individuals from the local development community requested the Planning Commission to recommend adoption of the proposed Hillside Development Ordinance Amendment with minor modifications. However, the Planning Commission recommended adoption of the ordinance without revision. On January 7, 1998, the Planning Commission recommended approval of the Negative Declaration issued by the Planning Director on March 8, 1996. FISCAL IMPACT: Projects which are proposed to be exempted from a Hillside Development Permit will no longer be required to pay a Hillside Development Permit application fee (currently $120 for a single family residence and $350 - $400 for additional development upon a manufactured slope which was approved and constructed through a previous grading or Hillside Development Permit). There will be some additional administrative costs to the City associated with this action in that these exemptions would still be subject to the Hillside Development standards and would be reviewed by staff for compliance through the grading plan and or building plan review processes. However, these additional administrative costs for Hillside Ordinance standards compliance review are not anticipated to be significant in that similar project details (i.e.; grading and architecture) are currently reviewed in the grading/building plan processes.

Development of Downhill Perimeter Slopes -5- 7 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 * 17 18 19 20 21 22 23 24 25 26 27 28 (0 The following types of development over a downhill perimeter manufactured slope shall be limited to a maximum of 6 vertical feet as measured from the existing grade at the top of slope: (a) Decks; and @I Retaining Walls. (ii) Deck surface areas shall be allowed to extend to the same point that a 6 foot vertical retaining wall would be permitted. (iii) No main or accessory building may encroach over the top/edge of a Downhill Perimeter Slope. C. The manufactured slope standards, within this section do not apply to manufactured slopes which are not located along perimeter property lines (including intervening manufactured slopes between split level pads which are located on a single lot). D. Volume of Grading 1. The volume of earth moved for cuts and fills shall be minimized. 2. The relative acceptability of hillside grading volume shall be determined by the following: Cubic Yards of Cut or Fill Grading per Acre of Cut and Fill Area (in acres) Relative Sensitivity of Hillside Grading Volume 0 -7,999 cubic yards/acre Acceptable 8,000 - 10,000 cubic yards/acre Potentially acceptable > 10,000 cubic yards/acre Unacceptable 3. The methodology for determining the volumes of both the cut and fill in cubic yards shall be calculated as follows. A grading and preliminary grading plan, shall be prepared and shall include: the cut or fill volumes noted for each particular cut or fill and the total volume of cut and fill for the project. The larger volume of the total cut or total fill volumes divided by the total graded area (in acres) shall equal the volume of hillside grading for the project. 4. Applications proposing grading volumes which are potentially acceptable (eight thousand to ten thousand cubic yards/acre of cut or fill) shall, on the preliminary grading plan, submit for review specific written findings justifying the reasons for the amount of grading, subject to the approval of the Planning Director and City Engineer. 5. Applications proposing grading volumes which are unacceptable (greater than ten thousand cubic yards/acre of cut or fill) shall be allowed only if they qualify as an exclusion or modification pursuant to Section 21.95.130 and 21.95.140 of this Chapter respectively. -6- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 - E.

Notwithstanding the building setback requirements of the underlying zone, all main and accessory buildings that are developed on hilltops and/or pads created on downhill perimeter slopes of greater than fifteen (15) feet in height shall be setback so that the building does not intrude into a .7 foot horizontal to 1 foot vertical imaginary diagonal plane that is measured from the edge of slope to the building. For all buildings which are subject to this slope edge building setback standard, a profile of the diagonal plane shall be submitted with all other development application requirements. 2. Building setbacks pursuant to this Chapter do not apply to: :: Slopes which are less than 15 feet in height; the intervening slopes of split-level pads which are located on a single lot, but do apply to the edge of slope of the lowest pad; C. downhill slopes which are located along the sideyards of residential lots; and d. substandard residential lots where the top/edge of slope setback standards would preclude a reasonable use of the property. 3. If a Downhill Perimeter Slope is regraded (filled) consistent with Subsection 21.95.120(C) of this Chapter, and a vertical retaining structure is used, then the required building setback shall be measured from the edge of slope which existed prior to regrading (filling). 4. Fencing proposed along a slope edge should be of an open design which does not visually extend the height of the slope. Exceptions to this provision may include, but are not limited to, noise attenuation walls, privacy walls or security walls. J. Roadway Design. 1. Hillside roadway design shall be consistent with the City’s Hillside Development Guidelines Manual. K. Hillside Drainage. 1.

Hillside areas where a Circulation Element roadway or a collector street must be located provided that the proposed alignment(s) are environmentally preferred and comply with all other City standards. 2. Grading volumes, slope heights and graded areas which are directly associated with Circulation Element roadways or collector streets, provided that the proposed alignment(s) are environmentally preferred and comply with all other City standards. 3. Hillside areas that have unusual geotechnical or soil conditions that necessitate corrective work that may require significant amounts of grading. 21.95.140 Modifications To The Development And Design Standards A. The decisionmaking body or official may approve a modification to the Hillside Development and Design Standards of Section 21.95.120 if it finds that the proposed development complies with the Purpose and Intent provisions of Section 21.95.010 and makes one or more of the following findings: 1. The proposed modification will result in significantly more open space or undisturbed area than would a strict adherence to the requirements of Section 2 1.95.120. 2. The proposed modification will result in the development of manufactured slopes which are more aesthetically pleasing and natural appearing than would a strict adherence to the requirements of Section 21.95.120. B. Any request for a modification to the development and design standards of this Chapter shall be accompanied by two preliminary grading plans. One plan shall illustrate how a site would be developed with a strict adherence to the requirements of Section 21.95.120. The second set shall illustrate the extent and type of the requested modification. This plan shall also be accompanied by any other documentation needed by the decisionmaking body to determine that the proposed modifications will result in a superior project with less adverse environmental impacts. C. If a modification is proposed to allow grading in excess of ten thousand cubic yards/acre of cut or fill, or a manufactured slope in excess of forty (40) feet in height, the applicant shall submit both written and graphic exhibits to justify the proposed grading to the satisfaction of the decisionmaking body or official. In addition, a detailed mitigation and landscaping plan shall be submitted as part of the application. This plan shall illustrate the mitigation measures and landscaping utilized to screen the proposed grading. D.

SUMMARY OF ENVIRONMENTAL FACTORS POTE NTIALLY AFFECTED: The summary of environmental factors checked below would be potentially affected by this project, involving at least one impact that is a “Potentially Significant Impact”, or “Potentially Significant Impact Unless Mitigation Incorporated” as indicated by the checklist on the following pages. - Land Use and Planning _ Transportation/Circulation _ - Population and Housing _ _ Biological Resources - - Geological Problems _ Energy and Mineral Resources _ _ Water _ Hazards - - Air Quality _ Noise - - Mandatory Findings of Significance Public Selvices Utilities and Service Systems Aesthetics Cultural Resources Recreation 1 Rev. 3/28/95 lB DETERMINATION. - (To be completed by the Lead Agency). On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. El I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION will be prepared. 0 I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. cl I find that the proposed project MAY have significant effect(s) on the environment, but at least one potentially significant effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT/MITIGATED NEGATIVE DECLARATION is required, but it must analyze only the effects that remain to be addressed. El I find that although the proposed project could have a significant effect on the environment, there WILL NOT be a significant effect in this case because all potentially significant effects (a) have been analyzed adequately in an earlier EIR / MITIGATED NEGATIVE DECLARATION pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR / MITIGATED NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project. Therefore, a Notice of Prior Compliance has been prepared. 0 Pranner Signature 3-q-96 Date CD:kr 2 Rev. 3/28/95 lQ ENVIRONMENTAL IMPACTS STATE CEQA GUIDELINES, Chapter 3, Article 5, Section 15063 requires that the City conduct an Environmental Impact Assessment to determine if a project may have a significant effect on the environment. The Environmental Impact Assessment appears in the following pages in the form of a checklist. This checklist identifies any physical, biological and human factors that might be impacted by the proposed project and provides the City with information to use as the basis for deciding whether to prepare an Environmental Impact Report (EIR), Negative Declaration, or to rely on a previously approved EIR or Negative Declaration. . A brief explanation is required for all answers except “No Impact” answers that are adequately supported by an information source cited in the parentheses following each question. A “No Impact” answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved. A “No Impact” answer should be explained when there is no source document to refer to, or it is based on project-specific factors as well as general standards. . “Less Than Significant Impact” applies where there is supporting evidence that the potential impact is not adversely significant, and the impact does not exceed adopted general standards and policies. . “Potentially Significant Unless Mitigation Incorporated” applies where the incorporation of mitigation measures has reduced an effect from “Potentially Significant Impact” to a “Less Than Significant Impact.” The developer must agree to the mitigation, and the City must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level. . “Potentially Significant Impact” is appropriate if there is substantial evidence that an effect is significant. . Based on an “E&Part II”, if a proposed project could have a potentially significant effect on the environment, but &I potentially significant effects (a) have been analyzed adequately in an earlier EIR or Mitigated Negative Declaration pursuant to applicable standards and (b) have been avoided or mitigated pursuant to that earlier EIR or Mitigated Negative Declaration, including revisions or mitigation measures that are imposed upon the proposed project, and none of the circumstances requiring a supplement to or supplemental EIR are present and all the mitigation measures required by the prior environmental document have been incorporated into this project, then no additional environmental document is required (Prior Compliance). . When “Potentially Significant Impact“ is checked the project is not necessarily required to prepare an EIR if the significant effect has been analyzed adequately in an earlier EIR pursuant to applicable standards and the effect will be mitigated, or a “Statement of Overriding Considerations” has been made pursuant to that earlier EIR. . A Negative Declaration may be prepared if the City perceives no substantial evidence that the project or any of its aspects may cause a significant effect on the environment. 3 Rev. 3/28/95 CM . If there are one or more potentially significant effects, the City may avoid preparing an EIR if there are mitigation measures to clearly reduce impacts to less than significant, and those mitigation measures are agreed to by the developer prior to public review. In this case, the appropriate “Potentially Significant Impact Unless Mitigation Incorporated” may be checked and a Mitigated Negative Declaration may be prepared. . An EIR must be prepared if “Potentially Significant Impact” is checked, and including but not limited to the following circumstances: (1) the potentially significant effect has not been discussed or mitigated in an Earlier EIR pursuant to applicable standards, and the developer does not agree to mitigation measures that reduce the impact to less than significant; (2) a “Statement of Overriding Considerations” for the significant impact has not been made pursuant to an earlier EIR; (3) proposed mitigation measures do not reduce the impact to less than significant, or; (4) through the E&Part II analysis it is not possible to determine the level of significance for a potentially adverse effect, or determine the effectiveness of a mitigation measure in reducing a potentially significant effect to below a level of significance. A discussion of potential impacts and the proposed mitigation measures appears at the end of the form under DISCUSSION OF ENVIRONMENTAL EVALUATION. Particular attention should be given to discussing mitigation for impacts which would otherwise be determined significant. 4 Rev. 3/28/95 221 Issues (and Supporting Information Sources): Potentially Significant Impact Potentially Significant Unless Mitigation Incorporated Less Than Significant Impact No Impact I.

The existing Hillside Development regulations were adopted in January, 1989 and this project constitutes the first comprehensive review and proposed revision to the Hillside Development regulations since it’s adoption. The objectives of ZCA 96-04/LCPA 96-01 include: A. Clarifying Specific Ordinance Provisions 1. That the primary intent and purpose of the ordinance is the protection of natural slopes. The existing ordinance does not distinguish between natural and manufactured slopes with respect to ordinance application. Definitions for natural slopes and manufactured slopes have been added to the Hillside Ordinance. The development of manufactured slopes shall continue to be regulated by the ordinance but shall not require a Hillside Development Permit. 2. The regrading of or encroachment into manufactured slopes of greater than 40% gradient shall be subject to new manufactured slope development and design standards. 3. That a Hillside Development Permit (HDP) is only required if the project proposes to develop a natural slope which has a gradient of 15% or greater and an elevation differential of greater than 15%. The existing ordinance indicates that an HDP is required if the property has a slope of 15% gradient or more and an elevation differential of greater than 15 feet, regardless of whether the identified slope area is proposed for development. B. Streamlining the Hillside Development Review Process 1. The following types of projects shall no longer require a Hillside Development Permit. However, these types of projects shall still be required to comply with the Hillside Development and Design Standards of the Hillside Ordinance (Section 21.95.080) and will be evaluated for compliance through the grading plan and building plan review processes. a. One single family dwelling unit on a residentially zoned lot; and b. The proposed regrading, slope alteration or other development encroachment on or into any manufactured slope or other graded area which has been graded consistent with a previously authorized grading permit. C. Ordinance Revisions to Address Shortcomings 1. Adds new development standards for the development of manufactured slopes of greater than 40% gradient. 12 Rev. 3/28/95 ~9 2. Adds specific building setbacks from top/edge of slopes of greater than 40% gradient as follows: a. 10’ - 15’ setback for buildings up to 15’ tall; b. 15’ - 20’ setback for buildings taller than 15’. 3. Allows the development of up to 50’ tall manufactured slopes if slope gradient is less than 50% (c 2:l) and slope is contour graded. 4. Similar to Circulation Element Roads, Collector Streets which are necessary to provide primary or secondary access to a property would be exempted from complying with the development prohibition of natural slopes greater than 40% gradient. In that this Zone Code Amendment is administrative in nature and is not associated with any specific development project, it will not directly or indirectly result in any significant environmental impacts. Any future development project processed pursuant to the amended Hillside Development regulations shall be required to undergo project specific environmental review. I. LAND USE AND PLANNING al b) c-e) The Hillside Development Ordinance is an overlay zone that includes hillside development regulations that apply to all projects which propose development of natural slopes which have a gradient of 15% or greater and an elevation differential of greater than 15 feet. The proposed.amendrnents are consistent with the City’s General Plan (Land Use Element and Open Space and Conservation Element) and would be applicable within all underlying zones of the City. The proposed zone code amendment would be consistent with all applicable environmental plans or policies adopted by other agencies including the Coastal Overlay Zone of the City’s Local Coastal Program. In that no physical development is proposed, this zone code amendment will not result in any impacts to existing land uses, agricultural resources, operations and farmlands or an established community. II. POPULATION AND HOUSING a-c) Since no physical development is proposed, this zone code amendment will not cumulatively exceed official regional or local population projections, induce substantial growth or displace existing housing. III. GEOLOGICAL PROBLEMS a-i) Because no physical development is proposed, this zone code amendment will not result impacts involving: fault rupture, seismic ground shaking, seismic ground failure, liquefaction, seiche, tsunami, or volcanic hazard, landslides, mudflows, erosion, unstable soil conditions, subsidence of the land or expansive soils. All future development 13 Rev- 3p8’g5 c3 0 processed pursuant to these amended Hillside Development regulations shall be required to apply for a grading permit and or Hillside Development Permit. The applicable standards and conditions associated with these permits will ensure that impacts associated with unstable earth conditions, geologic hazards, soil erosion, and topographic changes are adequately mitigated. IV. WATER a-i) This proposed zone code amendment is not associated with any development project, therefore the proposed amendment to the Hillside Development regulations will not result in: changes in the absorption rates, drainage patterns, or the rate and amount of surface runoff, exposure of people or property to water related hazards such as flooding, discharge into surface waters or other alteration of surface water quality, changes in the amount of surface water in any water body, changes in currents or the course or direction of water movements, changes in the quantity of groundwaters, altered direction or rate of flow of groundwater, impacts to groundwater quality, or substantial reduction in the amount of groundwater available for public water supplies. Future projects processed pursuant to these amended Hillside Development regulations shall be required to undergo environmental review and to adequately mitigate all identified water quality impacts. V. AIR QUALITY a-d) Since this amendment to the City’s Hillside Ordinance is not associated with any development project, no air quality impacts such as: a violation of an air quality standard, exposure of sensitive receptors to pollutants, alteration of air movement, moisture, or temperature or change in climate or the creation of objectionable odors will occur. Future projects processed pursuant to these amended Hillside Development regulations shall be required to undergo environmental review and to adequately mitigate all identified air quality impacts. VI. TRANSPORTATION/CIRCULATION a-g) This proposed zone code amendment to the City’s Hillside Ordinance is not associated with any development project and therefore will not result in traffic/circulation impacts such as: increased vehicle trips or traffic congestion, traffic hazards, inadequate emergency access or access to nearby uses, insufficient parking, hazards or barriers for pedestrians or bicyclists, conflicts with adopted policies supporting alternative transportation, or rail, waterborne, or traffic impacts. Future projects processed pursuant to these amended Hillside Development regulations shall be required to undergo environmental review and to adequately mitigate all identified transportation/circulation impacts. VII. BIOLOGICAL RESOURCES a-e) One of the primary purposes of the Hillside Ordinance is to assure that alteration to natural hillsides does not result in impacts to significant natural resource areas, wildlife habitats or native vegetation areas. Otherwise, since no specific development is proposed 14 Rev. 3/28/95 3 / with this zone code amendment, there will be no impacts to: endangered, threatened or rare species or their habitats, locally designated species, locally designated natural communities, wetland habitat or wildlife corridors. Future development projects processed pursuant to these amended hillside development regulations, shall be subject to environmental review and shall be required to adequately mitigate identified biological resource impacts. VIII. ENERGY AND MINERAL RESOURCES a-c) This proposed zone code amendment to the City’s Hillside Ordinance is not in conflict with adopted energy conservation plans. In that no development is proposed with this zone code amendment, the proposal would not use non-renewable resources in a wasteful and inefficient manner nor result in the loss of availability of a known mineral resource that would be of future value to the region and the residents of the State. Future projects processed pursuant to these amended Hillside Development regulations shall be required to undergo environmental review and to adequately mitigate all identified impacts to. energy and mineral resources. IX. HAZARDS a-e) No development is proposed as part of this zone code amendment. Accordingly, this Hillside Ordinance Amendment proposal would not result in: a risk of accidental explosion or release of hazardous substances, possible interference with an emergency response plan or emergency evacuation plan, the creation of any health hazard, exposure of people to existing sources-of potential health hazards, or increase fire hazard in areas with flammable brush, grass or trees. Future development projects processed pursuant to these amended regulations shall be required to mitigate all hazard impacts which are identified through the environmental review process. X. NOISE a-b) Since no development is proposed as part of this zone code amendment, this proposal would not result in increases in existing noise levels or the exposure of people to severe noise levels. Future development projects processed pursuant to these amended hillside development regulations, shall be subject to environmental review and shall be required to adequately mitigate identified noise impacts. XI. PUBLIC SERVICES a-e) No development is proposed with this zone code amendment, therefore, no public service impacts (i.e.; fire protection, police protection, schools, other governmental services and the maintenance of public facilities, including roads) will occur. Future development projects processed pursuant to these amended hillside development regulations, shall be subject to environmental review and shall be required to adequately mitigate identified public service impacts. 15 Rev. 3128195 34 XII. UTILITIES AND SERVICES SYSTEMS a-g) In that no project development is proposed as part of this zone code amendment, no impacts to utilities and service systems (i.e.; power, natural gas, communications systems, water treatment or distribution facilities, sewer or septic tanks, storm water drainage, solid waste disposal, or water supplies) will occur. Future development projects processed pursuant to these amended hillside development regulations, shall be subject to environmental review and shall be required to adequately mitigate identified utility and service system impacts. XIII. AESTHETICS a-c) One of the primary objectives of the Hillside Ordinance is to preserve the aesthetic qualities of natural hillsides by assuring that hillside development retains, where possible, the natural topographic landform. In that no development is proposed with this zone code amendment, no scenic vistas or scenic highways will be impacted, and no demonstrable negative aesthetic effects or light and glare impacts will occur. Future development projects processed pursuant to these amended hillside development regulations, shall be subject to environmental review and shall be required to adequately mitigate identified aesthetic impacts. XIV. CULTURAL RESOURCES a-e) This zone code amendment is not a development project and therefore will not impact cultural resources (i.e.; paleontological, archaeological, historical). Future projects processed pursuant to the amended Hillside Ordinance shall be required to undergo environmental review and to adequately mitigate cultural resource impacts. XV. RECREATION a-b) Since no development is proposed with this zone code amendment, no impacts to existing neighborhood or regional parks or other recreational facilities will occur. Future development projects processed pursuant to these amended hillside development regulations, shall be subject to environmental review and shall be required to adequately mitigate identified recreation impacts. XVI.

INTRODUCTION In 1995 the City Council approved a Community Development Workplan for Streamlining the Development Review and Permitting Processes. This Workplan recommended revisions to the City's Hillside Ordinance as a high priority streamlining work task. This Zone Code Amendment recommends specific amendments to the Hillside Development and Uses Generally chapters of the Zoning Ordinance which streamline the Hillside Development Permit process and clarify the Zoning Ordinance with respect to hillside development. Additionally, staff has undertaken a review of the Hillside Ordinance to identify and resolve specific Ordinance issue areas. Based upon this review, staff is recommending several Ordinance amendments. 111. PROJECT DESCRIPTION AND BACKGROUND This project (ZCA 96-04LCPA 96-01) is an amendment to the City's Hillside Development Ordinance and Uses Generally regulations (Chapters 21.95 and 21.53 of the Carlsbad Municipal Code) and its Local Coastal Program. The existing Hillside Development regulations were adopted in January, 1989 and this project constitutes the first review and proposed revision to this Ordinance since its adoption. The overall objectives of ZCA 96-04LCPA 96-01 include: 40 /“ . ’ ZCA 96-04LCPA 96-01 - hiLLSIDE ORDINANCE AMENDMEN I January 7,1998 A. Project Objectives 1. Streamline the Hillside Development permit procedures; 2. Clarify and simplify Ordinance provisions (Le. intent, applicability and standards) to make it more “user friendly”; and 3. Incorporate new development standards to address identified Ordinance issue areas. The City’s Zoning Ordinance also functions as the implementing zoning for Carlsbads Local Coastal Program (LCP). Accordingly, a Local Coastal Program Amendment is being processed to ensure consistency between the proposed amended zone code and the City’s LCP. IV. ANALYSIS Included below is a discussion and analysis of the specific Hillside Ordinance revisions associated with each above noted project objective. Reference can be made to Attachment “A” (Strikeournighlight version of amended Ordinance) or Exhibit “X to review in detail all text revisions. The recommendation for approval of this Zone Code AmendmentLocal Coastal Program Amendment was developed by analyzing it’s achievement of the overall project objecdves and it’s compliance/consistency with the Carlsbad General Plan and applicable Local Coastal Program policies. A. Project Objectives 1. Streamlining the Hillside Development Permit Procedures a. The primary objective of this Hillside Ordinance amendment is to streamline the Hillside Development Permit procedures. The Hillside Ordinance was adopted in 1989 for the purpose of providing the City with specific regulations to control excessive hillside grading and guide sensitive hillside development. Over the past eight years of experience with the Hillside Ordinance, concerns have been expressed (most notably by applicants proposing to develop either one single family dwelling unit on a residential lot or to develop a previously graded property or lot) that the Hillside Development Permit process is a time-consuming and duplicative discretionary permit process which might be more efficiently handled under a consolidated permit process. Accordingly, the Hillside Ordinance is proposed for amendment as follows: The addition of new Subsection 21.95.040(A) to exempt: (1) one single family dwelling unit on a residentially zoned lot; (2) additional development (i.e. regrading, slope alteration or building encroachment) of previously graded slopes which are located on a single lot; and (3) the development of underground utility systems from having to process a Hillside Development Permit. 1 ’ ZCA 96-04LCPA 96-01 - hlLLSIDE ORDINANCE AMENDMEN I January 7,1998 b. However, in order to ensure that the grading and structural development associated with these Hillside Permit exemptions are consistent with the purposes of the Hillside Ordinance, this new Exemption Subsection mandates that “any development (i.e. grading and architecture), associated with the development of one single family unit on a residentially zoned lot and the additional development of previously graded slopes on a single lot (proposed exempted projects), which encroaches into or on top of a natural or manufactured slope which has a gradient of 15% or more and an elevation differential greater than 15 feet, shall still be required to comply with the Hillside Development and Design Standards of the Ordinance (Section 21.95.120) and the City’s Hillside Development Guidelines, and shall be evaluated for compliance through required grading plan andor building plan review processes.” Any exemption which does not comply with Section 21.95.120 of the Ordinance and the Hillside Development Guidelines shall be required to process a Hillside Development Permit. The benefits associated with this ordinance amendment are that applicants (Le. owner-builders) proposing to build a single family residence upon an existing residential lot within the City will be spared the time (from 1 to 2 months) and expense ($120.00 per single family residence) of having to process a Hillside Development Permit in addition to required grading andor building permits. Similar benefits (Le. a $400.00 HDP application savings) will accrue to developers of previously graded industrial, commercial or residential lots in that a Hillside Development Permit would not be required in addition to other required discretionary permits (i.e. Planned Industrial Permit (PIP), or Site Development Plan(SDP)), or ministerial permits (i.e. building permit or grading permits). c. The existing Hillside Ordinance specifies that “no property which has a slope of 15% or more and an elevation differential greater than 15 feet shall be developed unless a Hillside Development Permit (HDP) has been issued.” Experience has shown that the requirement to process an HDP is clearly unnecessary under the scenario that a proposed development does not encroach upon the identified 15+ foot high 15% slope area(s) on a given property. Accordingly, the following Hillside Ordinance amendment is proposed: The addition of new Section 21.95.030(A) to specify that a Hillside Development Permit would only be required if a person proposes to grade, erect or construct into or on top of a slope which has a gradient of 15% or more and an elevation differential greater than 15 feet. The benefit of this revision is that a Hillside Development Permit would no longer be required for those projects which are not proposing to develop (encroach upon) onsite 15+ foot high, 15% and greater slope areas. 2. Clarifying and Simplifying the Ordinance A number of Hillside Ordinance revisions and a Zoning Ordinance revision are being recommended for the purpose of clarifying and simplifLing the Ordinance to make it more “user 4Q ‘ ZCA 96-04LCPA 96-01 - HILLSIDE ORDINANCE AMENDMEN 1’ January 7,1998 friendly.” These revisions include revising the Purpose and Intent Section to clarifL and focus the objectives of the Hillside Ordinance, the clarification of Zoning Ordinance provisions with respect to whether manufactured slopes of greater than 40% gradient are developable, the definition (quantification) of the term “sufficiently setback,” the addition of new Ordinance sections dealing with Amendments, Applications and Appeals and the reorganization of Ordinance subsections to make the Hillside Ordinance more readable and understandable. a. Section 21.95.010 Purpose and Intent, is proposed for amendment to distill the existing nine separate, yet overlapping, ordinance objectives into four more focused and clear objectives including: 1. Implementing the Land Use and Conservation Element hillside preservation related goals and objectives of the General Plan; 2. Ensuring that hillside conditions on a project basis are incorporated into the Planning Process; 3. Preserving the aesthetic qualities of natural hillsides and manufactured slopes; and 4. Assuring that hillside alteration is done in an environmentally sensitive manner. This revision provides more organization to the ordinance through the establishment of clear and focused ordinance objectives which directly relate to the development standards and required findings of the Hillside Ordinance. The following discussion addresses the Zoning Ordinance clarification regarding whether manufactured slopes of greater than 40% gradient are or aren’t developable. b. Existing Section 21.95.030@)(4) of the Hillside Ordinance states that “no development or grading can occur on undevelopable portions of a property, as defined by Section 21.53.230 of the Carlsbad Municipal Code.” Section 21.53.230 specifies that undevelopable lands include slopes with a gradient of greater than 40%. This section of Code does not address whether manufactured slopes of greater than 40% gradient are undevelopable. However, existing Section 2 1.95.090(b) of the Hillside Ordinance does state that “areas previously disturbed by authorized grading may be excluded from the requirements of the Hillside Ordinance.” Consistent with this provision, the City has historically allowed limited development of manufactured slopes of greater than 40% gradient through the Hillside Development Permit process. Accordingly, the following clarifications are proposed to Chapter 21.53 of the Zoning Ordinance and to the Hillside Ordinance to allow the development of “manufactured slopes” of greater than 40% gradient. A revision to existing Section 21.53.23O(b)(4) of the Zoning Ordinance to clarifL that “natural slopes” (and not “manufactured slopes”) with a gradient of greater than 40% shall be undevelopable. As part of this revision, a new Hillside Ordinance Section 2 1.95.020 (DEFINITIONS) has been added and includes definitions for “manufactured 43 ’ ZCA 96-04hCPA 96-01 - nlLLSIDE ORDINANCE AMENDMEN I January 7,1998 Page 5 slope” and “natural slope”. As discussed later in this report, new standards for the development of manufactured slopes (including those greater than 40% gradient) are proposed to be added to the Hillside Ordinance. In that the development of manufactured slopes will continue to be subject to the development standards of the Hillside Ordinance, Subsection 2 1.95.01 O(C) (PURPOSE AND INTENT) has been modified to specify that the Ordinance is intended to “Preserve andor enhance the aesthetic qualities of natural hillsides and manufactured slopes.. .” The benefits of these revisions are that: the existing confusion within the Hillside Ordinance and the Municipal Code is corrected whereby manufactured slopes of greater than 40% gradient would be allowed to be developed; and that the Purpose and Intent provisions of the Hillside Ordinance have not been compromised in that the development of “manufactured slopes” would continue to be reviewed (through grading plan andor building plan review processes) for compliance with the development standards provisions of the Ordinance. b. An Ordinance revision is proposed to define (quantify) the term “sufficiently set back” as follows: The existing Ordinance specifies that “buildings proposed for development on hilltops and on pads created on hillsides shall be sufficiently set back from the adjoining downhill slope.” This proposed amendment to new Subsection 2 1.95.120(1) (Slope Edge Building Setbacks), quantifies the term “sufficiently set back” through the addition of a specific slope edge building setback standard which applies to main and accessory buildings that are developed on downhill natural or manufactured slopes which are greater than 15 feet in height. Buildings proposed on such slopes shall not be setback less than the minimum setback requirements of the underlying zone but shall be setback so that the building does not intrude into a .7 foot horizontal to 1 foot vertical imaginary diagonal plane that is measured from the edge of slope to the building. (See Exhibits “F” and “G”.) The proposed edge of slope setbacks would not apply to: (1) manufactured or natural slopes which are less than or equal to 15 feet in height; (2) downhill slopes which are located along the sideyards of residential lots; (3) substandard residential lots where the top/edge of slope setback standard would preclude a reasonable use of the property; and (4) the intervening slopes of split level pads which are located on a single lot, but would apply to the edge of slope of the lowest pad. If the edge of a downhill manufactured slope is regraded (filled) and a vertical retaining structure (wall) is used, then the required building setback would be measured fiom the edge of slope which existed prior to regrading. Even without an existing quantified slope edge building setback standard, staff has historically negotiated a minimum building setback of 15 feet. The proposed building setback standard will provide an adequate separation between slope and structure. The benefit of this proposed revision is that specific (quantified) and reasonable building setback standards from edge of slope, which achieve an intended Ordinance objective (the elimination or reduction of views of vertical building forms which would be incompatible with hillside landforms) are clarified within the Ordinance. This revision will provide clear direction for Hillside Development Permit 44 ZCA 96-04LCPA 96-01 - MLLSIDE ORDINANCE AMENDME~v J Jan~wy 7,1998 applicants and staff, thereby enabling easier resolution of related setback issues and consequently expedited permit processing. c. A new section (21.95.050) addressing Amendments to Hillside Development Permits has been incorporated into the Ordinance. This new section includes: (1) the procedure for applying for a Hillside Development Permit Amendment, which is similar to other permit amendment procedures (e.g. PUDs and Master Plans) which exist within the zoning ordinance; (2) the criteria for when an amendment is required; and (3) the process for review of a HDP Amendment. Specifically, a Hillside Development Permit Amendment is required for any project which has an approved Hillside Development Permit, that is proposed for redesign and is not exempted from a Hillside Develoiment Permit. An amended project would be evaluated for compliance relative to the Hillside Ordinance Development and Design Standards (Le., Section 21.95.120). The process for review of a Hillside Development Permit Amendment is the same as for the adoption of a Hillside Development Permit. d. New Sections (21.95.060 and 21.95.070) addressing Applications for Hillside Development Permits and Review Process have been added to the Ordinance. Section 21.95.060 includes the procedures for processing a Hillside Development Permit for review and a provision that a permit processing fee will be charged. Revised Section 2 1.95.070 (Review Process) specifies that Hillside Development Permit Exemptions shall be evaluated for compliance with the standards of the Hillside Ordinance (Section 21.95.120) through the grading plan and/or building plan review processes. e. New Section 21.95.080 (Appeals) specifies that appeals of decisions on Hillside Development Permits shall be processed utilizing the same appeal procedures applicable to the other discretionary permits which are processed concurrent with the Hillside Development Permit request. Decisions regarding Hillside Development Permit Exemptions would be appealed using the same appeal procedure applicable to grading and/or building permits. f. The existing Hillside Ordinance includes three separate sections (2 1.95.070 - Modifications to the development and design standards, 21.95.080 - Non-residential development and 21.95.090 - Exclusions) pertaining to Hillside Ordinance exclusions or modifications. These three sections are proposed for revision for the purpose of clarifying the Ordinance. The revisions include: 1. Revising Section 2 1.95.130 (Exclusions) to specifically exclude the following from the requirements of the Hillside Ordinance without the necessity of decisionmaking body approval: (1) Hillside areas where a Circulation Element roadway or collector street must be located; (2) Grading volumes, slope heights and graded areas which are directly associated with Circulation Element roadways or collector streets; and 45- r’ f4? ZCA 96-04LCPA 96-01 - nlLLSIDE ORDINANCE AMENDMElY I’ ’ January 7,1998 (3) Hillside areas that have unusual geotechnical or soil conditions that require significant grading associated with corrective work. .. 11. Revising Section 21.95.140 (Modifications to the Development and Design Standards) to add the existing non-residential development standards modification provision (existing Section 21.95.080) to this Section and to delete Circulation Element roads and sites with unusual geotechnical/soils conditions from this Section. These two existing modification types are proposed as blanket exclusions, as discussed above. g. The overall Ordinance has been reorganized, i.e. reorganization of section sequence and elimination of duplicative provisions, for the purpose of making it more usable and clear, as follows: 1. Delete existing Section 21.95.030 (GENERAL RESTRICTIONS). The provisions of this Section have been incorporated into new Sections 21.95.030 (APPLICABILITY OF HILLSIDE DEVELOPMENT PERMIT), 21.95.070 (REVIEW PROCESS) and 21.95.090 (REQUIRED FINDINGS). These new Ordinance Sections more clearly identify for the user where such important Ordinance provisions are located. .. 11. Delete existing Section 21.95.040 (RESIDENTIAL DENSITY CALCU- LATION). The provisions of this Section are adequately and more appropriately covered under existing Carlsbad Municipal Code Section 21 S3.230 MENT RESTRICTIONS ON OPEN SPACE AND ENVIRONMENTALLY SENSITIVE LANDS). (RESIDENTIAL DENSITY CALCULATIONS, RESIDENTIAL DEVELOP- iii. Revise existing Section 2 1.95.090 (EXCLUSIONS). The exemption provision of this Section (21.95.090(a)) has been incorporated into new Section 21.95.040 (EXEMPTIONS FROM HILLSIDE DEVELOPMENT PERMIT) and the exclusion provisions of existing Section (2 1.95.090(b)) have either been incorporated into new Section 21.95.130 (Modifications) or revised and incorporated into new Section 21.95.120(B). iv. Delete existing Subsections 21.95.060(~)(1) (Area or Extent of Grading) and (2) (Modifications). The volume of grading provisions have been incorporated into new Subsection 21.95.120@) (Volume of Grading) and Area of Grading provisions have been deleted and a definition for “Total Graded Area” has been added to Definitions Sections 21.95.020. The modifications provisions within Subsection 21.95.060(~)(2) are also adequately covered under Section 21.95.140 (MODIFICATIONS TO THE DEVELOPMENT AND DESIGN STANDARDS). v. Delete provisions of existing Subsection 21.95.070(c) that deal with required landscaping of manufactured slopes or other graded areas which are approved as modifications to existing Hillside Ordinance Standards. These provisions are 46 n /I ZCA 96-04hCPA 96-01 - rilLLSIDE ORDINANCE AMENDMEN I’ ’ January 7,1998 vi. vii. ... v111. ix. unnecessary in that they are adequately covered within the City’s Landscape Manual policies and Grading Ordinance. Revise Local Coastal Program Hillside provisions (new Section 21.95.120(A)) to directly reference the applicable Coastal Overlay Zones (Chapters 21.38 and 2 1.203) of the Zoning Ordinance. Revise Section 21.95.120(G) (Screening of Manufactured Slopes) to specify that all manufactured slopes shall be landscaped consistently with the City’s Landscape Manual. Revise Section 21.95.120(H) (Hillside and Hilltop Architecture) to delete the architectural standards from the Ordinance. These standards will be incorporated into the City’s Hillside Development Guidelines manual and Section 21.95.120(H) will specifl that Hillside and hilltop structures shall be consistent with the architectural guidelines included within the City’s Hillside Development Guidelines manual. Revise Sections 2 1.95.120(3) and 2 1.95.120(K) to delete the specific Roadway Design and Hillside Drainage standards from the Ordinance. These standards will be incorporated into the City’s Hillside Development Guidelines manual and these sections of the Ordinance will specify that Roadway Design and Hillside Drainage shall be consistent with the City’s Hillside Development Guidelines Manual. 3. New Development Standards a. An integral component of the aforementioned Ordinance revision to allow the development of manufactured slopes of greater than 40% gradient and to exempt the development of manufactured slopes on a single lot, which were graded consistent with a previously authorized grading permit from having to process a Hillside Development Permit is the establishment of adequate development standards to regulate the development of such slopes. Accordingly, new manufactured slope development standards are proposed to be added as new Subsection 21.95.120(C) (Development of Manufactured Slopes of Over 40% Gradient). The proposed manufactured slope development standards apply to manufactured slopes with gradients of greater than 40% which have an elevation differential of greater than 15 feet which are located along perimeter property lines. No Ordinance restrictions are recommended to be placed upon interior manufactured slopes (those not located along perimeter property lines) which are located on a single lot due to the facts that these slopes typically do not include significant natural resources, and are generally less visible from public roads than perimeter slopes. There are different standards for “downhill” manufactured slopes and “uphill” manufactured slopes. New Section 2 1.95.020 (DEFINITIONS) includes definitions for “downhill perimeter slope” and “uphill perimeter slope”. 47 ‘ ZCA 96-04LCPA 96-01 - H~LLSIDE ORDNANCE AMENDMEN 1 January 7,1998 Page 9 Development that would be permitted on Downhill Perimeter Slopes includes: the construction of a maximum 6 foot tall retaining wall and the placement of additional fill material behind the wall to extend the pad area of a property (see Exhibit “A”), the construction of a deck, or the grading (cutting) of a pad area into the slope (see Exhibit “A”) for the purpose of once again increasing the pad area. No structures would be allowed to be developed on the manufactured pads which are developed along a slope face. The proposed Uphill Perimeter Slope development standards would allow grading (cutting) into the slope and building a maximum 6 foot tall retaining wall to increase the pad area of a property (see Exhibit “B”) or constructing a main or accessory building on top of the slope to the same point within that slope that a maximum 6 foot tall retaining wall would be located (see Exhibit “B”). Because Uphill Perimeter Slopes (including development upon them) would typically only be visible to the owner of the subject property, a provision has been included to allow uphill slope encroachment to the required building setbacks of the underlying zone for the construction of decks (see Exhibit “C”). Manufactured slopes developed pursuant to these standards would also be subject to the other Hillside Development standards within Section 21.95.120. b. Revise the existing contour grading standard (new Subsection 21.95.12O(F)(l) to specify that all manufactured slopes which are greater than twenty (20) feet in height and two hundred feet in length and are located adjacent to or are substantially visible from a Circulation Element road, collector street or useable public open space area, shall be contour graded. The existing Hillside Ordinance specifies that contour grading shall only be required when a manufactured slope of greater than 30 feet in height or 200 feet in length is created. As a consequence, the typical manufactured slope developed within the City pursuant to these provisions is less than or equal to 30 feet in height and 200 feet in length and is not contour graded. The proposed standard modification would require manufactured slopes which are greater than 20 feet in height (rather than 30 feet in height) and 200 feet in length which are located adjacent to or are substantially visible from a Circulation Element road or collector street or useable public open space area to be contour graded. The benefit of this revision, is that the requirement to contour grade is more appropriately focused on those manufactured slopes which are most visible to the public (along major streets and useable public open space areas). Slopes which are less visible (i.e. those located along rear and sideyards which are typically screened by fences and structures) would not be required to be contour graded. Another benefit of revising the contour grading standard from greater than 30 feet in heightl200 feet in length to greater than 20 feet in heightl200 feet in length is that a greater number of more natural appearing contoured slopes will be created, thereby satisfying one of the primary objectives of the Hillside Ordinance, which is to ensure that hillside development preserves the natural appearance of hillsides. Consistent with this objective and revision a definition for “contour grading” has also been added to new Section 2 1.95.020 (DEFINITIONS). c. Revise the existing permitted manufactured slope height standard (new Subsection 21.95.120(E)(l)) from 30 feet to 40 feet. r”. ? ZCA 96-04LCPA 96-01 - HILLSIDE ORDINANCE AMENDMEh I’ January 7,1998 ’ The existing ordinance specifies that manufactured slopes shall not be greater than 30 feet in height. This standard appears to be based primarily upon the Engineering Department standard to construct drainage benches in manufactured slopes which are greater than 30 feet in height. An unintended effect of restricting manufactured slope heights to 30 feet is that in terraced hillside developments, where structures range from 24 to 35 feet in height, there is no apparent landscape relief between structures located on the terraces (see Exhibit “D). The net effect is that from view corridors (roads), hillside development appears to be dominated by structures. The proposal to revise the manufactured slope height standard from 30 feet to 40 feet will allow for a minimum 10 feet of vertical landscaped separation between typical residential structures which are terraced along a hillside (see Exhibit “E”). d. Amend Subsections 21.95.130(A)( 1) and 21.95.130(A)(2) to: exclude collector streets from having to comply with the development prohibition of natural slopes which have a gradient of greater than 40%, exclude collector streets from having to comply with the maximum 40 foot high manufactured slope standard, to allow the graded area and grading volumes associated with the construction of both Circulation Element Roads and collector streets to be excluded from project grading area and grading volume totals provided that the proposed road alignment is environmentally preferred and complies with all other City standards. The Hillside Ordinance currently excludes Circulation Element Roads from complying with the development standards of the Hillside Ordinance. This Ordinance exclusion was based upon the realization that the construction of the City’s major circulation system could not comply with the Hillside Ordinance development standards due to the existence of significant topographic constraints throughout the entire City. Collector streets generally intersect with Circulation Element Roads and provide primary or secondary access to residential neighborhoods and nonresidential projects. Because the grading required to construct a collector street is generally determined by the alignment and grade of the intersecting Circulation Element Road, it is recommended that collector streets be similarly excluded from complying with Hillside Ordinance development standards provided that the proposed road alignment (Circulation Element and/or collector) is environmentally preferred and complies with all other City standards. Consistent with this objective and revision, a definition for “collector street” has also been added to new Section 21.95.020 (DEFINITIONS). The proposed revision to exclude graded areas and grading volumes associated with Circulation Element Roads from project graded area and grading volume totals is an Ordinance clarification, in that existing Section 21.95.090 excludes Circulation Element Roads from the requirements of the Ordinance. For the reasons discussed above, staff is also recommending that graded areas and grading volumes associated with collector streets likewise be excluded from project graded area and grading volume totals. e. Modify the provisions within the Hillside Ordinance and Uses Generally Chapter (21.53.230(~)), which prohibit the development of slopes with a gradient of greater than 40%, to allow the development of such slopes. As discussed earlier in this report, the Hillside ordinance and Section 21 S3.230 of the Carlsbad 47 ZCA 96-04LCPA 96-01 - dLLSIDE ORDINANCE MNDMEh I’ January 7,1998 Municipal Code currently prohibit the development of slopes with gradients of greater than 40%. The existing prohibition provision (Section 2 1.95.030(b)(4)) of the Hillside Ordinance specifies that “no development or grading can occur on undevelopable portions of a property (i.e. slopes with an inclination of greater than 40% or more), as defined by Section 21.53.230 of the Carlsbad Municipal Code”. The specific wording in Section 21.53.230 of the Carlsbad Municipal Code was prepared based upon the recommendations of the Citizens Committee for the Review of the Land Use Element of the Carlsbad General Plan (1985). A review of the Citizens Committee minutes pertaining to slopes with gradients of greater than 40% reveals that the primary objectives were to not allow residential density credit for such slopes and to not allow the development of such slopes when they comprise prominent topographic features of a property. However, it was never the intent of the Citizens Committee to outright prohibit the development of such slopes. A strict interpretation of Section 21.53.230 could preclude the ability to develop much of the remaining vacant hillside property within the City. Based upon this realization, the existing Hillside Ordinance (Section 21.95.090) was written to include various “Exclusions” fiom the standards of the Hillside Ordinance including: (1) slopes with gradients of greater than 40% which are less than 15 feet in height and less than 4,000 square feet in area, which are not a part of the surrounding generalized slope and (2) small, isolated ravine (slopes of greater than 40% gradient) where there is no substantial evidence that the project will have a significant impact on the environment as determined by the Planning Director. The City has historically allowed the development of such slopes pursuant to these exclusions. However, these specific exclusions are not broad enough in their definition to allow for the development of other slopes with gradients of greater than 40% which are not prominent landform features worthy of preservation. In order to: (1) more accurately address one of the intended objectives of the Citizens Committee (1995) and of the Hillside Ordinance, which is the preservation of prominent landform features; and (2) provide specific measurable criteria (slope height and land area) which more accurately define what a prominent landform feature is, a standard modification is proposed. The proposed standard modification would delete the above noted two exclusions for slopes with gradients of greater than 40% and replace these exclusions with the following standard (new Subsection 21.95.120(B)): “Natural slopes which have all of the following characteristics shall be undevelopable: 1. 2. 3. 4. A gradient of greater than 40%; and An elevation differential of greater than 15 feet; and A minimum area of 10,000 square feet; and The slope comprises a prominent land form feature. The above noted standard addressing permitted development of slopes with gradients of greater than 40%, references (Section 21.95.120(B)(2)) permitted exceptions (exclusions or modifications included in Sections 21.95.130 and 21.95.140 of the Hillside Ordinance). These modifications include the same exclusions/modifications currently included within the Hillside Ordinance (i.e. sites which require more grading due to geotechnical or soils problems, extensive grading required to accommodate a circulation element road or collector street and cases where significantly more open space would be achieved in addition to an additional modification (see f below)). 3‘ P- rn ZCA 96-04LCPA 96-01 - HILLSIDE ORDINANCE AMENDMELUT January 7,1998 ’ Consistent with this proposed revision, Section 21.53.230(b)(4) of the Carlsbad Municipal Code has also been modified to specify that no residential development shall occur on slopes with gradients of greater than 40% gradient except as permitted pursuant to Section 21.95.120p) of the Carlsbad Municipal Code. f. The existing Hillside Ordinance includes three findings to allow for modifications to the Development and Design Standards of the Hillside Ordinance. An additional finding (Subsection 21.95.140(A)(2)) to allow for the modification to the Development and Design Standard, is proposed as follows: “The proposed modification will result in the development of manufactured slopes which are more aesthetically pleasing and natural appearing than would a strict adherence to the requirements of the ordinance.” This finding is proposed to enable and encourage the development of creatively designed manufactured slopes, (i.e. slopes rich in horizontal and vertical undulation) which would be more aesthetically pleasing than the natural landforms or manufactured slopes that the standards of the ordinance would otherwise achieve. B. General Plan The General Plan Land Use and Open Space and Conservation Elements include a number of hillside preservation and design policies which are listed below. 1. Land Use Element Policy C.3 - “Ensure that grading for building pads and roadways is accomplished in a manner that maintains the appearance of natural hillsides.” 2. Open Space and Conservation Element Policy C.3 - ‘‘Assure that development on hillsides ‘relates to the slope of the land in order to preserve the integrity of the hillsides.” 3. Open Space and Conservation Element Policy C.12 - “Require that grading be accomplished in a manner that will maintain the appearance of natural hillsides and other landforms where possible.” 4. Open Space and Conservation Element Policy C.14 - “Implement ordinances limiting the density, intensity and character of development of hillside areas and ridges, and provide standards for sensitive grading where development of hillsides is allowed.” This proposed Hillside Development Ordinance amendment is consistent with the applicable policies and programs of the General Plan in that the hillside development and design standards which are proposed will function to regulate the grading and development of hillsides, thereby preserving the appearance and integrity of natural hillsides and manufactured slopes. 5/ ’ ZCA 96-04LCPA 96-01 - WLLSIDE ORDINANCE AMENDMEN I January 7,1998 C. Local Coastal Program Currently the LCP implementation does not include the Hillside Ordinance. However, Subsection 2 1.95.120@) of the existing Hillside Ordinance specifies that, “All development on slopes of twenty-five percent or greater within the coastal zone shall comply with the requirements of the coastal overlay zone.” This specific development standard has been supplemented with the following provision: a. That all hillside development processed pursuant to this Chapter shall be consistent with all applicable provisions of the certified Local Coastal Program and will not result in significant adverse impacts to coastal resources. With this proposed amendment, the Hillside Development Ordinance is clearly consistent with applicable coastal policies (including the slope preservation policies) of Carlsbad’s Local Coastal Program. Any hillside development proposal within the Coastal Zone shall be required to comply with all applicable Local Coastal Program policies and provisions. The LCP amendment will add the amended version of the Hillside Ordinance and the modifications to Chapter 21.53.230 to the implementation portion of all of the City’s LCP segments. This will accomplish the required consistency between the City’s Zoning Ordinance and its LCP. V. ENVIRONMfiNTAL REVIEW The Planning Director has determined that this Zone Code Amendment/Local Coastal Program Amendment (ZCALCPA) to amend the City’s Hillside Development and Uses Generally regulations (Chapters 21.95 and 21.53 of the Carlsbad Municipal Code), will not have a significant impact on the environment and therefore has issued a Negative Declaration on March 8, 1996. The environmental analysis (EIA Part 11) concluded that this ZCA/LCPA will not result in any physical, biological or human environmental impacts because future development projects processed pursuant to‘this amended Hillside Ordinance will be subject to project specific environmental review and the revised development standards are comparable to the existing standards with respect to environmental protection. Therefore, no significant environmental impacts are anticipated to occur. There were no letters of comment received during the public review period for this Negative Declaration.

ZCA 96-04/LCPA 96-01 - HILLSIDE ORDINANCE AMENDMENT - A Zone Code Amendment and Local Coast Program Amendment to revise the City’s Hillside Development Ordinance and Uses Generally regulations (Chapters 21.95 and 21.53 of the Carlsbad Municipal Code to: (1) streamline the Hillside Development Permit process, (2) clarify and simplify the Hillside Development Ordinance to make it more user friendly, and (3) incorporate new development standards to address identified Ordinance issue areas. Chairperson Noble announced that the Commission’s action on this item is not final and it will be forwarded to the City Council for its consideration. Project Planner, Chris DeCerbo presented the staff report in the form of slide and overhead projections. He described this project as an amendment to the City’s Hillside Development Ordinance and Uses Generally Chapter 21.53 of the Carlsbad Municipal Code. The objectives are to streamline the Hillside Development Permit process, clarify and simplify the Ordinance to make it more “user friendly”, and to add and revise Development Standards to address identified ordinance issue areas. The Hillside Ordinance was adopted in 1989 for the purpose of providing the City with specific regulations to control excessive hillside grading and guide sensitive hillside development and this project constitutes the first review and proposed revision since its adoption. Mr. DeCerbo reviewed each of the ordinance revisions which are associated with each of the project objectives and stated that two ordinance provisions are proposed to streamline the Hillside Permit process, the first of which is directed to the applicability section of the Hillside Ordinance. This section specifies that “no property which has a slope of 15% or more and an elevation differential greater than 15 feet shall be developed unless a Hillside Development Permit (HDP) has been issued.” Experience has shown that the requirement to process an HDP is clearly unnecessary under the scenario that a proposed development does not encroach upon the identified 15+ foot high 15% slope area(s) on a given property. Accordingly, the following Hillside Ordinance amendment is proposed: The addition of new Section 21.95.030(A) to specify that a Hillside Development Permit would only be required if a person proposes to grade, erect or construct into or on top of a slope which has a gradient of 15% or more and an elevation differential greater than 15 feet. The second proposed amendment to the Hillside Ordinance is in response to concerns that have been expressed (most notably by applicants proposing to develop either one single family dwelling unit on a residential lot or to develop a previously graded property on a lot) that the Hillside Development Permit process is a time-consuming and duplicative discretionary process which might be more efficiently handled under a consolidated permit process. Consequently this proposed amendment would exempt certain projects from having to process a Hillside Development Permit. These exemptions include: (I) one single family dwelling unit on a residential lot; (2) the additional development of previously graded slopes on a single lot; and (3) underground utilities. r PLANNING COMMISSION January 7, 1998 Page 3 Four Hillside Ordinance revisions and a Zoning Ordinance revision are being recommended for the purpose of clarifying and simplifying the ordinance to make it more user friendly. Section 21.95.010 Purpose and Intent is proposed for amendment to distill the existing nine separate, yet overlapping, ordinance objectives into four more focused and clear objectives including: 1. Implementing the Land Use and Conservation Element hillside preservation related goals and objectives of the General Plan; 2. Ensuring that hillside conditions on a project basis are incorporated into the Planning Process; 3. Preserving the aesthetic qualities of natural hillsides and manufactured slopes; and 4. Assuring that hillside alteration is done in an environmentally sensitive manner. This revision provides more organization to the ordinance through the establishment of clear and focused ordinance objectives which directly relate to the subsequent development standards and the required findings for the approval of a Hillside Permit. The second revision would eliminate conflicting provisions within the City Zoning Ordinance regarding whether manufactured slopes of greater than 40% gradient are or are not developable. Existing Section 21.95.030(b)(4) of the Hillside Ordinance states that "no development or grading can occur on undevelopable portions of a property, as defined by Section 21 53.230 of the Carlsbad Municipal Code." Section 21 53.230 specifies that undevelopable lands include slopes with a gradient of greater than 40%. This section of Code does not address whether manufactured slopes of greater than 40% gradient are undevelopable. However, existing Section 21.95.090( b) of the Hillside Ordinance does state that "areas previously disturbed by authorized grading may be excluded from the requirements of the Hillside Ordinance." Consistent with this provision, the City has historically allowed limited development of manufactured slopes of greater than 40% gradient through the Hillside Development Permit Process. Accordingly, the following clarifications are proposed to Chapter 21.53 of the Zoning Ordinance and to the Hillside Ordinance to allow the development of "manufactured slopes" of greater than 40% gradient. A revision to existing Section 21.53.230(b)(4) of the Zoning Ordinance will clarify that "natural slopes" (and not "manufactured slopes") with a gradient of greater than 40% shall be undevelopable. As part of this revision, a new Hillside Ordinance Section 21.95.020 (DEFINITIONS) has been added and includes definitions for "manufactured slope" and "natural slope". New standards for the development of manufactured slopes (including those greater than 40% gradient) are proposed to be added to the Hillside Ordinance. In that the development of manufactured slopes will continue to be subject to the development standards of the Hillside Ordinance, Subsection 21.95.01oO (PURPOSE AND INTENT) has been modified to specify that the Ordinance is intended to "Preserve andlor enhance the aesthetic qualities of natural hillsides and manufactured slopes . . ." The benefits of these revisions are that: the existing confusion within the Hillside Ordinance and the Municipal Code is corrected whereby manufactured slopes of greater than 40% gradient would be allowed to be developed; and that the Purpose and Intent provisions of the Hillside Ordinance have not been compromised in that the development of "manufactured slopes" would continue to be reviewed (through grading plan andlor building plan review processes) for compliance with the development standards provisions of the Ordinance. The third Ordinance revision is proposed to define the term "sufficiently set back" from the edge of slope. 77 MINUTES rl r' PLANNING COMMISSION January 7, 1998 Page 4 The existing Ordinance specifies that "buildings proposed for development on hilltops and on pads created on hillsides shall be sufficiently set back from the adjoining downhill slope." This proposed amendment to new Subsection 21.95.120(1) (Slope Edge Building Setbacks), quantifies the term "sufficiently set back" through the addition of a specific slope edge building setback standard which would apply to main and accessory buildings that are developed on downhill natural or manufactured slopes which are greater than 15 feet in height. Buildings proposed on such slopes shall not be set back less than the minimum setback requirements of the underlying zone but shall be set back so that the building does not intrude into a .7 foot horizontal to 1 foot vertical imaginary diagonal plane that is measured from the edge of slope to the building. The proposed edge of slope setback would not apply to: (1) manufactured or natural slopes which are less than or equal to 15 feet in height; (2) downhill slopes which are located along the side yards of residential lots; (3) substandard residential lots where the topledge of slope setback standard would preclude a reasonable use of the property; and (4) the intervening slopes of split level pads which are located on a single lot, but would apply to the edge of slope of the lowest pad. If the edge of a downhill manufactured slope is regraded (filled) and a vertical retaining structure (wall) is used, then the required building setback would be measured from the edge of slope which existed prior to regrading. This revision will provide clear direction for Hillside Development Permit applicants and staff, thereby enabling easier resolution of related setback issues and consequently expedited permit processing. The fourth ordinance clarification revision adds new sections to the ordinance addressing Amendments to Hillside Development Permits, applications, review processes, and appeals. These new sections will provide guidance for ordinance users. New Development Standards An integral component of the Ordinance revision to allow the development of manufactured slopes of greater than 40% gradient and to exempt the development of manufactured slopes on a single lot, which were graded consistent with a previously authorized grading permit from having to process a Hillside Development Permit, is the establishment of adequate development standards to regulate the development of such slopes. Accordingly, new manufactured slope development standards are proposed to be added as new Subsection 21.95.120(c) (Development of Manufactured Slopes of Over 40% Gradient). The proposed manufactured slope development standards apply to manufactured slopes with gradients of greater than 40% which have an elevation differential of greater than 15 feet which are located along perimeter property lines. No Ordinance restrictions are recommended to be placed upon interior manufactured slopes (those not located along perimeter' property lines) which are located on a single lot due to the facts that these slopes typically do not include significant natural resources, and are generally less visible from public roads than perimeter slopes. There are different standards for "downhill" manufactured slopes and "uphill" manufactured slopes. New Section 21.95.020 (DEFINITIONS) includes definitions for "downhill perimeter slope" and "uphill perimeter slope". Development that would be permitted on Downhill Perimeter Slopes includes: the construction of a maximum 6 foot tall retaining wall and the placement of additional fill material behind the wall to extend the pad area of a property, the construction of a deck, or the grading (cutting) of a pad area into the slope for the purpose of once again increasing the pad area. No structures would be allowed to be developed on the manufactured pads which are developed along a slope face. The proposed Uphill Perimeter Slope development standards would allow grading (cutting) into the slope and building a maximum 6 foot tall retaining wall to increase the pad area of a property or constructing a main or accessory building on top of the slope to the same point within that slope that a maximum 6 foot tall retaining wall would be located. Because Uphill Perimeter Slopes (including development upon them) MINUTES 7 f fh PLANNING COMMlSSlON January 7,1998 Page 5 would typically only be visible to the owner of the subject property, a provision has been included to allow uphill slope encroachment to the required building setbacks of the underlying zone for the construction of decks. Manufactured slopes developed pursuant to these standards would also be subject to the other Hillside Development standards within Section 21.95.120. Several slides were shown, depicting several scenarios, each of which were explained by Mr. DeCerbo. The second new development standard is a revision to the existing contour grading standard to specify that all manufactured slopes which are greater than twenty (20) feet in height and two hundred feet in length and are located adjacent to or are substantially visible from a Circulation Element road, collector street or useable public open space area, shall be contour graded. The existing Hillside Ordinance specifies that contour grading shall only be required when a manufactured slope of greater than 30 feet in height or 200 feet in length is created. As a consequence, the typical manufactured slope developed within the City pursuant to these provisions is less than or equal to 30 feet in height and 200 feet in length and is not contour graded. The benefit of this revision, is that the requirement to contour grade is more appropriately focused on those manufactured slopes which are most visible to the public along major streets and useable public open space areas. Another benefit of revising the contour grading standard from greater than 30 feet in height1200 feet in length to greater than 20 feet in height1200 feet in length is that a greater number of more natural appearing contoured slopes will be created. The third new proposed Standard revision would revise the existing permitted manufactured slope height standard from 30 feet to 40 feet. The existing ordinance specifies that manufactured slopes shall not be greater than 30 feet in height. This standard appears to be based primarily upon an Engineering requirement to construct drainage benches in manufactured slopes which are greater than 30 feet in height. An unintended effect of restricting manufactured slope heights to 30 feet is that in terraced hillside developments, where structures range from 24 to 35 feet in height, there is no apparent landscape relief between structures located on the terraces. The net effect is that from view corridors (roads), hillside development appears to be dominated by structures. The proposal to revise the permitted manufactured slope height standard to 40 feet will allow for a minimum 10 feet of vertical landscaped separation between typical residential structures which are terraced along a hillside. Commissioner Monroy asked if this proposal affects density and suggested that this issue be addressed during discussion following the staff report. The fourth new development standard would exempt collector streets from complying with the development standards of the Hillside Ordinance provided that the proposed road alignment is environmentally preferred and complies with all other City standards. The Hillside Ordinance currently excludes Circulation Element Roads from complying with the development standards of the Hillside Ordinance. This Ordinance exclusion was based upon the realization that the construction of the City's major circulation system could not comply with the Hillside development standards due to the existence of significant topographic constraints throughout the entire City. Collector streets generally intersect with Circulation Element Roads and provide primary or secondary access to residential neighborhoods and nonresidential projects. Because the grading required to construct a collector street is generally determined by the alignment and grade of the intersecting Circulation Element Road, it is being recommended that collector streets be similarly excluded from complying with Hillside Ordinance development standards. MINUTES 79 /4 PLANNING COMMISSION January 7, 1998 Page 6 The fifth new development standard would modify the provisions within the Hillside Ordinance and Uses Generally, Chapter 21.53 which currently prohibits the development of slopes with a gradient of greater than 40%, to allow the development of such slopes. The specific wording in Section 21.53 of the Municipal Code basically states what lands are developable and what density credit can be obtained and was prepared based upon the recommendations of the Citizens Committee for the Review of the Land Use Element of the Carlsbad General Plan in 1985. A review of the Citizens Committee minutes pertaining to slopes with gradients of greater than 40% reveals that the primary objectives were to not allow residential density credit for such slopes and to not allow the development of such slopes when they comprise prominent topographic features of a property. However, it was never the intent of the Citizens Committee to outright prohibit the development of such slopes. A strict interpretation of the Code could preclude the ability to develop much of the remaining vacant hillside property within the City. Based upon this realization, the existing Hillside Ordinance was written to allow for the development of some slopes with gradients greater than 40%, including those which are less than 15 feet in height and less than 4,000 square feet in area, which are not a part of the surrounding generalized slope and some small, isolated ravines where there is no substantial evidence that the project will have a significant impact on the environment. These specific exclusions do not appear broad enough in their definition to allow for the development of other slopes with gradients of greater than 40%, which clearly are not prominent landform features. In order to more accurately address one of the intended objectives of the Citizens Committee (1 985) and of the Hillside Ordinance, which is the preservation of prominent landform features and provide specific measurable criteria which more accurately define what a prominent landform feature is, a standards modification is proposed. The proposed modification would define an undevelopable natural slope as having the following characteristics: 1. 2. 3. 4 A gradient Qf greater than 40%; and An elevation differential of greater than 15 feet; and A minimum area of 10,000 square feet; and A finding that the slope does comprise a prominent land form feature, which would be interpreted through an Environmental Review process. The last proposed revision includes an additional finding to allow for modification to the Development and Design Standards of the Hillside Ordinance. The additional proposed Standards modification finding is, “The proposed modification will result in the development of manufactured slopes which are more aesthetically pleasing and natural appearing than would a strict adherence to the requirements of the ordinance.’’ Mr. DeCerbo concluded his presentation by stating that this proposed Zone Code Amendment and this Local Coastal Program Amendment achieve the overall project objectives and is consistent with the General Plan and the Local Coastal Program. Therefore, staff is recommending approval of ZCA 96-04 and LCPA 96-01. Commissioner Monroy stated that in his opinion, by allowing greater heights more flat area will be required for any development and that, in turn, could reduce the density that was originally allowed under the Density Zoning. Mr. DeCerbo replied that a reduction in density is conceivable, but in the context of trying to create an additional amenity, this will provide some flexibility for the developers . Commissioner Compas referred to a letter received from Mr. Jerry Livingston of the Building Industry Association of San Diego County (a copy of which is on file in the Planning Department), and asked Mr. DeCerbo to comment on Mr. Livingston’s remarks. PLANNING COMMISSION January 7,1998 Page 7 Mr. DeCerbo stated that regarding the Contour Grading, the Building Industry Association (BIA) is suggesting that areas of less than 4000 square feet are not appropriate for effective engineering of contour graded slopes and further suggests that slope heights of 30 feet and lengths of 500 feet would be more appropriate. Mr. DeCerbo’s response was that the City has seen no evidence of BIAS reasoning. Regarding the proposed Building Setback Standard, Mr. DeCerbo stated that after countless meetings, staff feel that although there has not been total consensus, the City and the BIA have come very close to consensus with the standard that is being proposed (.7 ft. horizontal to 1 foot vertical). The requested fifteen foot setback, as requested by the BIA, is currently the required rear yard setback for our small lot Planned Unit Development, Residential. Mr. DeCerbo further stated that he does not agree with the BIAS proposal. Commissioner Heineman asked what the BIA is proposing in place of the .7 ft. horizontal. Mr. DeCerbo replied that there is no specific proposal in the letter but that it has been suggested by other developers that .67 ft. would work. Some, however, don’t believe there would be a problem with .7 and others have not voiced opinions. The effect of the City’s proposal will be to restrict the building height to 21.42 feet. Commissioner Heineman asked if he is correct in his assumption that staff is not necessarily trying to reduce the building heights, but are actually trying to integrate some “stepping” that will break up the vertical plane. Mr. DeCerbo replied that the proposed standard might achieve that, in some cases, and if not, there will be some breakup of the roof plane to create a little bit of visual softening. For clarification, Commissioner Monroy asked if the objective would be met if a deck was placed at a height of seventeen feet and a rail installed around it. Mr. DeCerbo replied that the objective would be met, and that the railing would be there for safety purposes. Commissioner Welshons asked how a manufactured slope with a 40% gradient is created. Mr. DeCerbo responded that a manufactured slope is one that is created after previous grading has been done to prepare a property for development. Regarding the ability to go twelve feet out over a slope, Commissioner Welshons asked if that twelve feet is the maximum allowed. Mr. DeCerbo replied that it is the maximum with a 2 to 1 slope. Commissioner Welshons asked if it would be appropriate to put a cap on how far out over a slope, a deck or any other roofless object, can be built. Mr. Wayne interjected that the “6 and 12” rule or allowing encroachments of 6 feet vertical or 12 feet horizontal originated from allowing a maximum wall height of 6 feet on a manufactured slope. Since most manufactured slopes in the City are graded at 2 to 1 or 50%, that generates a horizontal encroachment of 12 feet. Allowing the same 6 foot vertical encroachment into or on a gentler slope could produce a greater horizontal encroachment than 12 feet. However, the amendment clarifies the issue because it sets the maximum encroachments at 6 feet vertical and 12 feet horizontal. 8/ MINUTES r‘ PLANNING COMMISSION January 7,1998 Page 8 Commissioner Welshons asked Mr. Wayne how this revision will affect Green Valley. Mr. Wayne replied that it will not affect Green Valley because the slopes there are “constrained” slopes and are designated “open space”. They are still undevelopable by the terms of Code Section 21.53.230 that defines what lands are developable and those that are not. Commissioner Welshons asked if the Rosalina Development can not extend their properties out over a slope. Mr. Wayne replied that there are protective easements for public access across the rear of all of those properties next to the lagoon and desiltation basin so they cannot extend over slopes. Regarding “natural slopes that have all of the following characteristics shall be undevelopable”, a gradient greater than 40%, a minimum of 10,000 square feet, etc., Commissioner Welshons asked how that 10,000 square feet is measured. Mr. DeCerbo stated that it is an aerial measurement of a flat surface. Mr. Wayne further stated that the city has equipment that traces around the boundaries of a property and measures the area inside those boundaries. Commissioner Welshons, referring to another of the revisions regarding contour grading, pointed out that it specifies that “. . . all manufactured slopes which are greater than 20 feet in height and 200 feet in length . . .” and asked if both conditions must apply. Mr. DeCerbo responded affirmatively. Chairperson Noble opened Public Testimony and offered the invitation to speak. Jerry Livingston, Staff Counsel for the Building Industry Association, 6336 Greenwich Dr., Suite A, San Diego, stated that as stated in his letter, it is the opinion of the BIA that contour grading is much more viable with a larger area of land to grade. He pointed out that the slides showing very large contoured grading are in reality about 100 feet high and they look very nice. However, he stated, when the height and area become considerably smaller, they become extremely difficult to engineer and the effects could probably be better achieved through landscaping. He further stated that that is an area where staff and the BIA agreed to disagree, very early in the process. Regarding the setback, Mr. Livingston stated that their real concern is for the smaller lot and the significant reduction in the footprint of a dwelling. He quoted his builders as having said that they are finding it very difficult to build the square footage (without the second story) that they would like and still adhere to the required setback. Commissioner Monroy asked if Mr. Livingston considers soil when he talks about slope contouring. Mr. Livingston replied that certainly soil is taken into consideration, in that one of the main areas of concern is drainage. Dale Greenholm, Project Design Consultants, 701 B Street, San Diego, stated that, contrary to the beliefs of many of those concerned, he feels that the proposed revisions will create a situation where builders will end up creating more of a plane effect and it will not allow for different interesting vertical articulation. He further stated that he believes that the proper place to address the setbacks is in the Architectural Guidelines in the Planned Development Ordinance and the Zoning Ordinances. Commissioner Welshons asked Mr. Greenholm if he has ever purposely not used the minimum setback and instead allowed for an even greater setback than required. 84 MINUTES f4 PLANNING COMMISSION January 7,1998 Page 9 Mr. Greenholm responded by stating that they look at the existing zoning and General Plan on a piece of .property and that defines what can be done with the property and whether or not the builder will elect to build to the minimums. Each builder must produce a product that is economically viable and must take advantage of any or all of the opportunities presented to him. He further stated that contour grading is aesthetically pleasing but people want back yards and useable space around them and the builder has to be sensitive to the needs and wants of the prospective home buyer. Bob Ladwig, Ladwig Design Group, 703 Palomar Airport Road, Suite 300, Carlsbad, speaking to the subject of density, stated that contour grading will definitely have an effect on density. Mr. Ladwig stated that his concern and question is, where there is open space that has been set aside as habitat, is that considered useable open space if there is a trail there? He went on to state that in his opinion the answer would be no, because it would be a very limited use and the city still has not accepted any trail for maintenance and there are no official trails in the city’s system, to date. Mr. Ladwig voiced his concern about the developer being required to set aside open space for habitat and then have to do contour grading adjacent to that open space where there may be very limited future public viewing of those slopes that face down onto that open space. Mr. Ladwig also pointed out that there are a number of Master Plan communities, in varying stages of development, and asked how this Hillside Ordinance Amendment will affect those projects that are currently negotiating through the system. Mike Howes, Hofman Planning Associates, 2386 Faraday Avenue, Suite 120, Carlsbad, speaking on behalf of two developers, in particular, as well as others, stated that overall, this is a significant improvement over the existing ordinance. Regarding the setbacks on “top of slopes“, Mr. Howes stated that he is in agreement with the BIA and suggested that some additional wording be added to Page 7, Paragraph I, Line 11 of the Hillside Ordinance Amendment, as follows: “, . .hillside landforms. Notwithstanding the building setback requirements of the underlying zone, all main and accessory buildings that are located on top of slopes that are adjacent to or are substantially visible from a circulation element roadway, collector street or useable public open space . . .” Mr. Howes stated that if it is in the interior of a project and is not really visible, would it be that much of a concern? Seeing no one else wishing to testify, Chairperson Noble closed Public Testimony. Responding to previous testimony, Mr. DeCerbo disagreed with Mr. Greeholm’s assessment of the contour grading issue. He agreed with Mr. Ladwig that contour grading does take away some developable property and it could affect density or the size of residential or non-residential product and that is why it is not practiced. However, that does not mean that in small lot neighborhoods the City will not continue to get common recreation areas which is a mandate of the Planned Development Ordinance. Also, units located on the top of slope would have larger than normal rear yards. Regarding the definition of useable open space, Mr. DeCerbo stated that staff does not know if any of the habitat that is set aside as open space will ever have trails. However, in the event that Carlsbad does have trails and open spaces that are useable and there are no objections from the various agencies for passive recreational use, it is important to incorporate those elements into the amendment. Commissioner Compas asked if Mr. DeCerbo agrees with Mr. Ladwig and Mr. DeCerbo replied that he doesn’t believe that it needs to be defined any more than it already is. Mr. Wayne further stated that staff does not agree with Mr. Ladwig’s suggestion about removing the requirement for contour grading next to open space. Regarding projects that are already “in the mill”, Mr. DeCerbo pointed out that there are two provisions in the ordinance; 1) under Section 2195030(b), “any application for a Hillside Development Permit which was deemed complete, prior to the effective date of the Ordinance, reenacted in this Chapter, shall not be 83 MINUTES PLANNING COMMISSION January 7, 1998 Page IO subject to the amended provisions of this Chapter but shall be processed and approved or disapproved pursuant to the Ordinance superceded by this Ordinance.”; and 2) under Section 21 95040(c), “any project that has received final approval of a Hillside Development Permit, prior to the effective date of the Ordinance, is exempted from the provisions of this Chapter, provided that such permit or approval has not expired or is not otherwise revoked, and the development is in accordance with the existing Hillside Development Permit and related approvals.” Mr. Wayne stated that the Hillside Ordinance sits in Title 21 and is a Planning Document and has always been intended to include Hillside Architecture. There are architectural guidelines that go along with it and the City is very concerned how houses look on these hills. Also, the way this ordinance has been constructed, it will help to emeliorate the problem of very large houses on small lots by setting the structures further back from visible area. Commissioner Welshons asked Mr. DeCerbo if he agrees with Mr. Howes suggestion of adding language to the amendment. Mr. DeCerbo replied that while he understands Mr. Howes’ reasoning, it is entirely possible that there could be questions as to what is visible and what is not, and if that should ever happen, he would prefer that the ordinance remain as it is. Commissioner Welshons asked staff to clarify the meaning of “side yard”. Mr. DeCerbo stated that “side yard” is defined in the Zoning Ordinance which says that a side yard will be determined in varying situations but is relative to the width of the lot and the location of the front yard. Typically, the narrowest part of a lot would be considered a side yard. Mr. Wayne quoted the Zoning Ordinance as follows: “Side yard means the yard between the main building and the side lot lines, extending from the rear line of the required front yard or a front lot line where no front yard is required, to the rear line of the main building or the rear line of the rearmost building, if there is more than one building. The width of which side yard shall be measured horizontally from and at right angles to the nearest point of the side lot line towards the nearest part of a main building.” A CTlO N : Motion by Commissioner Heineman, and duly seconded, to adopt Planning Commission Resolution No. 3939, recommending approval of the Negative Declaration issued by the Planning Director and adopt Planning Commission Resolutions No. 3940 and 3941, recommending approval of ZCA 96-04 and LCPA 96-01, based upon the findings and subject to the conditions contained therein. In discussion, all Commissioners stated their support for this project.

As you are probably aware, the existing industrial land in Carlsbad is being rapidly absorbed and additional industrial land will be needed in the City of Carlsbad to satisfy demand generated by business relocating to Carlsbad and existing Carlsbad businesses that are expanding. Our Carlsbad Oaks North development is going to be the next major industrial park to develop in Carlsbad. We have been meeting with Planning Staff to work out the details of the Hillside Development Ordnance Amendment. In particular one area that we appeal to you to change is the area in the proposed amendment regarding “contour grading”. Staff has been asking for contour graded slopes to be slopes with varying 2:l to 6:l inclinations. The effect of this request is to substantially reduce the buildable portions of lots and increase the maintenance costs. There is an impending shortage of industrial land in Carlsbad, and the only effect of the contour grading requirements is to reduce the amount of industrial land available in Carlsbad. We would point to the approved Cornerstone Corporate Center, PIP 97-04 on the north side of Palomar Airport Rd. as an example of a project that can keep 2: 1 slopes and use enhanced landscaping to achieve a high quality appearance. We propose that the Hillside Development Ordnance Amendment delete the contour grading requirement, retain the current 2: 1 slope requirements, and achieve natural looking slopes by requiring enhanced landscaping. We thank you for the opportunity to make comments to the proposed amendment of the Hillside Development ordnance, and we would be happy to answer questions. Sincerely, Paulk.&hang, President PKT:tt 71 06 Lantana Terrace Carlsbad, CA 92009 February 16, 1998 City Of Carlsbad City Council Meeting Dear Council Members: It is my understanding that the issue of lowering the steep slope requirements in order to build on such property is being considered. As informed people I am sure you are aware that some property is simply not suitable for development. Regulations insuring that certain hillsides and steep slopes will remain natural make sense. If these requirements are weakened a number of undesirable events take place: houses may have to be built on stilts, land fill may have to be used, houses will be built for which no insurance can be obtained, the likelihood of erosion and flooding (I’m sure you can picture this happening in light of recent weather conditions) will be increased, wildlife will be without a habitat and property values, in all probability will decrease. Please do the intelligent, foresightful thing and dismiss this consideration, leaving the general plan intact. Sincerely, a2=-7& Barbara E. Tice February 15,1998 . Honorable Councilpersons: 1 . I hereby present my strong objection to the current effort to relax the maximum slope requirement for residential construction by amending the so-called Hillside Ordinance. Hillside ordinances are in effect in most forward-looking municipalities to prevent the kind of landslide and building-collapse disasters that had been suffered without such laws in Glendale, Malibu, and Bluebird Canyon in Laguna Beach. The Carlsbad ordinance was weakened a few years back, and this is an effort to firther gut it. The developer’s interest in maximizing profits by building on steeper slopes is understandable. The City’s responsibility should be to assert and protect the public interest and safety. However this responsibility is undercut by elected officials’ overwhelming need for reelection campaign funds. The largest and most reliable souzce of those finds is the development industry, and the finds are available, Santa Claus-like, to those officials who have been, in the developers’ view, not naughty, but nice. I ask that the City Council stand by the present protective regulations in the interest of public safety. Sincerely, n 7304 Borla Place Carlsbad, CA 92009
