It is subordinate to the City's Subdivision Ordinance and the Subdivision Map Act. This manual fulfills certain requirements of those documents by providing detail necessary not only for the processing of subdivision maps but for the design of required public improvements and private street standards related to development. This Subdivision Manual is a guide. It provides guidance both for processing subdivision documents and for preparing those documents. There has been no attempt to anticipate all possible situations that may arise during the subdivision development process. Therefore, the standards and criteria developed within this manual will not address every situation. It is anticipated that the Chula Vista standards and design criteria will apply in the majority of cases. SECTION I - GENERAL INFORMATION I. DEFINITIONS The definitions listed in this section are in addition to those listed in the Subdivision Map Act and the Subdivision Ordinance. A. Legal Lot: Is a parcel established or set forth by one of the following means: 1. A deed describing the property recorded prior to March 4, 1972. 2. A recorded subdivision map or parcel map. 3. Either of the above means combined with a City approved and recorded boundary adjustment plat. *NOTE: A parcel is not necessarily a legal parcel just because there is an Assessor's parcel number assigned to it. B. Preliminary Plat: This plat is an informal sketch submitted to the Planning Department for their advice regarding City requirements, constraints on development, recommendations for development and for the most expedient and efficient method of processing the subsequent map. C. Tentative Map: The tentative subdivision or parcel map is an official submittal depicting the overall development contemplated. Upon approval by the City, the tentative subdivision (parcel) map constitutes an agreement between the developer and the City. D. Final Map: Is a map that delineates the boundary of the subdivision by bea~ing and distances; indicates the procedure of survey; and establishes the boundary of each lot within the subdivision. II. Controlling Documents A. Subdivision Map Act: The current Subdivision Map Act takes precedence over all other documents and ordinances relative to the subdivision of land. B. Subdivision Ordinance: The City of Chula Vista Subdivision ordinance · expands, delineates and regulates those items that the Subdivision Map Act allows the local jurisdiction to regulate. c. Grading Ordinance: The grading ordinance number 1797 as amended by ordinance 1877 and this manual shall govern grading and plan preparation of grading plan. -2- Xp SECTION II - PARCEL MAPS I. GENERAL: A parcel map procedure is used to create a division or consolidation of land under the provisions of the Subdivision Map Act and the Subdivision Ordinance. Both a tentative parcel map and final parcel map are required, however, under some circumstances, the requirements for a tentative parcel map may be waived by the Director of Planning and the City Engineer, who have joint responsibility for the processing and approval of tentative parcel maps. A tentative map shows existing topography, boundaries and improvements plus any proposed changes. An example of when the requirement to submit a tentative parcel map might be waived would be when all public improvements have already been installed, no grading is. proposed, and the only changes proposed are changes to lot line or boundaries. The City Engineer shall determine if a tentative parcel map will be waived. If waived, a letter from the City Engineer placing conditions on the subdivision will be sent the subdivider in the same manner as if conditionally approving a tentative parcel map. A. Lots. All lots created or divided by parcel maps shall conform to City standards and no existing building or structure shall be made non-conforming with respect to yard or other zoning requirements by the process. B. Easements. No existing easement in favor of the public shall be rendered impractical by the creation of a parcel on any parcel map. C. Improvements. The design and construction of required improvements shall conform to the criteria and standards contained in this manual and dictated by local ordinance. D. Improvement Agreement/Security Instruments. A parcel map improvement agreement similar to a subdivision improvement agreement per Section 18.16.090 of the City Code may be required for improvements in conjunction with parcel maps. Said agreements, along with security instruments, shall be fully executed prior to recordation of parcel map. E. Final parcel maps shall be prepared either by a registered Civil Engineer with a license number of 33965 or less or a licensed land surveyor. II. TENTATIVE PARCEL MAP: A. Fees.

The preliminary plat should indicate: 1. Location of site. 2. Number, size, and design of lots. 3. Location and width of streets. 4. Location, purpose, and width of existing and proposed easements. 5. Nature and extent of proposed grading. 6. Environmental impact analysis. 7. Other data which might affect proposed development. II. TENTATIVE MAPS: A. General. Figures 6 and 7 are respectively samples of a tentative subdivision map and a check list. The following information amplifies the information contained in those figures. B. Purpose and Concept of Tentative Map. The tentative subdivision map is made for the purpose of depicting the overall development contemplated. While not precise in detail, such as pavement structural section, it is specific in those items which can be predetermined such as street dimensions and right of way. Upon approval by the City, the tentative subdivision map constitutes an agreement between the developer and the City relative to approximate subdivision design to include its grading, zoning, and public improvements. All subsequent work by the developer and his engineer is based on understanding reached at tentative map stage. Obviously the tentative map should be as complete and specific as reasonably possible. The tentative map is filed with the Planning Department and reviewed by both the Planning Commission and the City Council. The Commission acts in the capacity of an advisory body to the Council. -20- C. Filing Tentative Map. A minimum of 28 blue line copies and a reproducible copy of the tentative map shall be filed with the Director of Planning. Filing shall be accompanied by necessary fees, two copies of preliminary title report, a preliminary soils report and any other data necessary to clarify the submission. D. Size and Scale. The map shall be clearly and legibly reproduced in a minimum size of eighteen inches by twenty-six inches (18" x 26"} at a scale of not less than one inch equals one hundred feet (l" = lO0'). E. Data to be shown on Map. 1. All subdivisions in Chula Vista will be assigned a tract designation by the Planning Department upon filing a tentative map. Tract designations will be used in addition to subdivision names and will be shown on all tentative maps, final maps, improvement plans and other references to that development. A typical designation such as "CHULA VISTA TRACT NO. 74-5, UNIT NO. 2" indicates that subject development was the 2nd unit of the 5th subdivision filed in lg74. 2. A vicinity map with north arrow and scale shall be shown. 3. In addition to a scale in words or figures, a graphic scale shall be drawn so that the scale will be truly representative, in the event the map is enlarged or reduced. 4.

C. Final Map Format and Content. The final map consists of a minimum of a title sheet and such number of map sheets as may be necessary. Figures g and lO are samples of Sheets 1 and 2 of a subdivision map and Figure ll subdivision map check list. l. General. a. The final map shall be clearly and legibly drawn or typed in black waterproof drawing ink on linen or mylar. All signatures shall be in opaque black drawing ink and seals will be embossed or stamped with reproducible ink. b. The dimensions of each sheet of the map shall be eighteen inches (18") by twenty-six inches (26"}. c. A border line shall be drawn completely around each sheet, leaving an entirely blank margin of one inch {l"}. d. The subdivision title and unit number shall be shown on each sheet, centered and below the upper margin. Maps filed for "Reversion to Acreage" or for "Resubdivision" shall include such terminology in the subdivision title. e. The map number shall be shown on the right hand side of the upper margin on each sheet. f. The number of each sheet and the total number of sheets comprising the map shall be shown just below the upper right hand margin on each sheet. g. All printing to be a minimum of 1/8" in height. 2. Title Sheet. Centered under the subdivision title shall be a generalized legal description of the area being subdivided, followed by the total number of lots within the subdivision and the gross area in acres. Required certificates are included in Figure 9, except for variations indicated in Appendix "A". Certificates by the City Engineer and City Clerk must be adjacent to a margin so that embossing seals can be used. Appendix "A" contains examples of various certificates and jurats which may be required. ~29- 3. Procedure of Survey & Index Sheet: a. Figure l0 is a sample of the Procedure of Survey and Index Sheet for a Final Subdivision Map. This sheet will normal ly contain: {1) A vicinity map with north arrow and scale indicated. (2) Procedure of Survey Map (Scale: l" = 200') or a Procedure of Survey and Index Map {Scale: l" ~ 200'}. An index of sheets may be shown by using symbols shown in legend or by using symbols in conjunction with dotted lines representing sheet coverage. {3} Legend. (4) Basis of bearings. (5} Civil engineer or land surveyor's certificate. (6) Any other certificate which could not fit on Sheet l, the Title Sheet. b. The subdivision boundary shall be tied to the Lambert Projection, California Coordinate System, Zone VI. This shall be accomplished by tying the subdivision boundary to a minimum of two established horizontal control monuments on file in the office of the City Engineer. The adjoining corners of all adjoining subdivisions shall be identified by lot and block numbers, subdivision name and place of record or other proper designation. c. In some cases (for a small subdivision containing only a few lots) the final map may require only two sheets in which case the procedure of survey may be included on the map sheet and the index map would not be necessary. 4. Map Sheets. a. Scale. The scale of the map sheets shall be sufficient to ~ll details clearly and in no case shall be less than one inch {l"} equals one hundred feet (100'). Enough sheets shall be used to accomplish this end. The scale both in words or figures and graphically shall be shown on each map sheet. b. A north arrow shall be shown on each map sheet. -30- c. ~ An accurate and complete boundary survey shall f the land to be subdivided. A traverse of the exterior boundaries of the tract, and of each block, when computed from field measurements on the ground, must close within a limit of one part in ten thousand {l:lO,O00} feet of perimeter. The boundary of the subdivision shall be indicated on the final map by a colored dashed boundary line approximately one-sixteenth {1/16} of an inch wide. All lines shown on the map which do not constitute a part of the subdivision, and any area enclosed by such line shall be labeled "not a part of this subdivision." All such lines shall be dashed. d. All reference data adjacent {or in the near vicinity) such as section corners, blocks, lot lines, recorded maps, etc. shall be shown. e. Dimensions, Bearings and Curve Data. The final map shall show all survey and mathematical information and data necessary to locate all monuments and to locate and retrace any and all interior and exterior boundary lines appearing thereon, including bearings, basis of bearings, and distances of straight lines, and radii and arc lengths for all curves, and such information as may be necessary to determine the location of the centers of curves. f. Lots and Blocks. All lots and blocks and all parcels offered for dedication for any purpose shall be particularly delineated and designated with all dimensions, boundaries, and courses clearly shown and defined in every case. Parcels offered for dedication other than for streets or easements shall be designated by number. Sufficient linear, angular and curve data shall be shown to determine readily the bearing and length of the boundary lines of every block, lot and parcel which is a part thereof. Sheets shall be so arranged that no lot is split between two or more sheets and wherever practicable, blocks in their entirety shall be shown on one {1} sheet. No ditto marks shall be used for lot dimensions. Lot numbers shall begin with the numeral "l" and continue consecutively throughout the tract, with no omissions or duplications. In adjacent units of subdivisions of less than lO0 lots per unit bearing the same name and developed' by the same subdivider, lots. shall be numbered consecutively throughout all units. Setback lines will be shown. Open space lots shall be lettered "A", "B", "C", etc. within each unit. g. Streets. The map shall show the right of way lines of each ~being dedicated and widths of any existing dedications. The widths and locations of adjacent streets and other public properties within fifty {50) feet of the subdivision shall be shown. If any street in the subdivision is a continuation or approximately a -31- continuation of an existing street, the conformity or the amount of non-conformity of such street to such existing street shall be accurately shown. Whenever the center line of a street has been established or recorded, the date shall be shown on the final map. In cases where access rights relinquishment is requested, or necessary, that portion adjacent to the street have short hash marks along that section and shall be shown in the legend thus: "///////indicates abutter's rights of access relinquished hereon." All private streets shall be shown on the subdivision map and shall be clearly identified as a "Private Street." · h. Easements. The sidelines of all easements existing and proposed easements shall be shown by fine dotted lines. If an easement already of record cannot be definitely located, a statement of the existence, the nature thereof and its recorded reference must appear on. the title sheet. Distances and bearings on the side lines of lots which are cut by an easement must be arrowed or so shown that the map will indicate clearly the actual lengths of the lot lines. The widths of all easements and sufficient ties thereto to definitely locate the same with respect to the subdivision must be shown. All easements shall be clearly labeled and identified. If an easement shown on the map is already of record, its recorded reference shall be given. If an easement is being dedicated by the map, it shall be set out in the owner's certificate of dedication. Easements for street trees shall be provided in conformance with City Standards. In any instance where sidewalk is waived or a less-than-standard right of way width is approved, the easement for street trees shall have a minimum width of lO feet. Easements reserved by the owner for public utilities or for other purposes ~hall be shown on the map and so designated thereon. In subdivisions which consist of condominiums with more than one lot and there are private utilities or drainage facilities crossing lot boundaries, an easement to subsequent owners shall be delineated on the final map in accordance with Section 18.20.150 of the City Code. i. Inundation lines for the design flood shall be clearly indicated whenever a stream, channel, or body of water is within or adjacent to the subdivision.- E.

A. The preferred basis of bearing is a Lambert Grid bearing on the California State Coordinate System. The bearing may be obtained from a previously recorded survey {or from a new survey} meeting the following requirements. 1. If the bearing is being established, it shall be established from at least two United States Coast and Geodetic Survey monuments of second order (or better) and be shown on a previously recorded map. 2. A triangulation or trilateration net shall be shown on the map and, furthermore, the bearing and distance ties from the existing control stations to the point being established on the subdivision must be given. 3. A similar following note shall be shown on the map if the basis is the California Coordinate System: "The basis of bearings for this map is the California Grid bearing between Station (nameI and Station (name) , 1.e., (bearing) " 4. The following note shall also be included with the basis: NOTE: "Bearings, distances and coordinates are in terms of the California Coordinate System, Zone 6, based locally on order stations {name) and {name " B. A basis of bearing may be a reference line from a recorded subdivision, parcel map, or record of survey map, provided that at least two found or established points of record are on that line. If this method is used, the basis of bearing must state: "The basis of bearings for this map is the {east, west, etc.) line of (name of ref. map) , Map No. i.e., (reference bearing) " C. Basis of bearing is unacceptable when based on: 1. No record bearing is shown on the line; 2. NO monuments of records are found on the line; 3. Found monuments on the line are designated "No Record"; 4. The bearing of the line is assumed; 5. It is a'line on a City tie-point sheet, improvement drawing, State highway map, or any other map that is not recorded. -42- II. Nonumentation. A. General. 1. A monument is set or placed at a particular location to mark a point of a boundary or survey. -Monuments shall be a permanent type of monument such as a pipe, concrete cylinder, or steel rod. 2. {a) All "found" monuments shall be fully identified by type, condition {rusted, bent, etc.} lot and block number, tract name and number, place of record, section, township and range, or other proper identification; and if they appear on a previously recorded map, record of survey, County Road Survey, City Tie Point Sheet, State Highway or other public record, the reference number of the record shall be shown. {b) All found monuments shown on final maps shall be flagged in the field for inspection by the City prior to recordation of the map. 3. All monuments found or set shall be tied into the subdivision by bearing and distance. In case there is a variance between the "record" tie and the "measured" tie, to a found monument, the record bearing and distance shall be shown in parenthesis; for example {SBg°SI'20"E, 13g.75', R. of S. 8006). 4. The map shall show monuments set at the true corners, angle points and curve points around the boundary of the parcel or parcels being surveyed, except as noted below and in Section IV C-3. 5. In cases where conditions make it physically impossible to monument the true corner, the monuments may be shown as having been set at an offset, in which case the bearing and distance shall be shown between the corner and the monument. 6. Proper notation shall be made concerning any points reset by ties. 7. The subdivider shall be reponsible for having a registered civil engineer or a licensed land surveyor: {a} Replace any monument or bench mark {as required by this manual or located in making a survey} that is disturbed or destroyed'before acceptance of all improvements. (b) Reestablish at or near the surface any monument which will be buried during the process of subdivision development before acceptance of improvements. -43- 8. Monuments, except for boundary monuments, may be set after acceptance of improvements. A certificate of such intent shall be placed upon the map and signed by a registered civil engineer or licensed surveyor as appropriate. 9. All "pipe" monuments and "lead and disc" monuments set shall be permanently and visibly marked with the license or certificate number of the surveyor or ci'vil engineer setting it, each number to be preceded by the letters L.S. or R.C.E. stamped on a metal disc. B. T~pes of ~numents. Authorized monuments to be set in the City of C ula Vista, and the symbols to be used on maps are as shown on Figure 13. C. ~nument Locations. 1. If a recorded monument is found at the location of a monument required to be set, said monument shall be used in lieu of replacing it with a new monument, provided this existing monument is in satisfactory condition and is a type more permanent than wooden hubs. 2. Boundary monuments shall be set at each boundary angle point or point of curvature and at intermediate points not more than 1,O00 feet apart. 3. Lot corner monuments shall be set at the true lot corner unless lead plugs and metal discs are set on an offset line, then they shall be set at the designated offset on the prolongation of the lot lines. When offsets are used they shall be clearly indicated upon the title sheet and on each of the final map sheets. Lot corners which are coincident with subdivision boundary corners shall be monumented as required for boundary monuments. 4. Each angle point and point of curve of a street shall be monumented by a pair of monuments located equidistant from the street centerline and behind the existing (or future) curb location. In 'a cul-de-sac only the beginning curve need be monumented; and only the beginning and ending of knuckle curves need be monumented. 5. All street intersections shall be monumented with permanent monuments with monument boxes per CVCS 15. If the monument cannot be set at the intersection location because of obstacles such as sewer manholes, the City Engineer will determine the offset location for setting the monument. -44- ·//( , D. Monument Performance Guarantees. 1. A monumentation surety in an amount stipulated by the engineer of work and approved by the City Engineer, to cover the cost of setting monuments in a subdivision shall be posted in conformity with Code requirements. 2. Setting of boundary monuments shall- be accomplished prior to approval of a parcel map or subdivision map. 3. Within thirty days following recordation of a subdivision map (or acceptance of improvements in the case of delayed monumentation), the civil engineer or land surveyor responsible for the survey will make an appointment with the City Engineer for a joint inspection of all monuments noted on map as being "found" or "set". In lieu of a joint inspection, said civil engineer or land surveyor may "flag" all monuments, so that the City Survey Party may inspect said monumentation. The City Survey Party shall inspect each mapped area to ensure that all "found" and set monuments noted on map are as described, and in the stated location; and that all monuments noted or being replaced have been replaced. Any discrepancies noted will be corrected by the civil engineer or land surveyor responsible for the preparation of the parcel map or subdivision map. SUbdivision survey monumentation bonds will not be released until such corrective action to the satisfaction of the City Engineer has been accomplished. 4. In the event of the death, disability, retirement or refusal of the civil engineer or land surveyor charged with the responsibility for setting monuments, an amended map shall be filed by another civil engineer or land surveyor in accordance with the provisions of Section 66498 of the Subdivision Map Act. Monuments would then be set by the substitute engineer or land surveyor. E. Bench Marks. 1. Procedure. a. All vertical control in subdivisions shall be referenced to established City bench marks. b. The subdivider shall show on Sheet No. 1 of the subdivision improvement plans, the reference bench mark on which all subdivision elevations are based. c. Such reference bench mark may be an established City bench mark or it may be a new reference bench mark established by the subdivider. (1) A copy of field survey level notes shall be submitted to the City Engineer by the subdivider showing levels taken from an established City bench mark to any new reference bench mark established for the subdivision. {2) When a new reference bench mark is established by the subdivider the Survey Section shall field check the elevation of such bench mark by running check levels from an established City bench mark. Upon approval of the elevation of the new bench mark by the City's Survey Party Chief he shall record such bench mark in the City Bench Mark Book. -46 - SYMBOL PURPOS£ TYPe' MONUMENTru FOUND SET SECTION CORNERS 3°° DIAMETER GALV.

GENERAL DESIGN CRITERIA. A. Block Design A residential block is an area which is entirely bounded by streets, highways, ways {except alleys), or by the exterior boundary or boundaries of a subdivision. The maximum length of a residential block shall be 1,500 feet. B. Lot Design Each lot shall constitute a practical building site appropriate for the type of development contemplated, and shall include adequate "pad areas". l. "Pad area" is defined as the area of lot exclusive of all slopes. Check the proposed house plans for the subdivision to determine if the "pad area" permits the structure on it with adequate level areas. 2. The minimum lot area is established by the Zoning Ordinance or Development Standards. (A lot may have the required "lot area" but may not have adequate "pad area" because of the slopes on the lot. Therefore, the "pad area" actually dictates the size of the lot. (Custom lots are not usually affected by "pad area" because the house will be designed to fit the site.) , ~ ~'I~E, ~ (ST~mNDA.0 R-' LOT 7000 SOFT $ ~IN~ MiNiMUM LOT FRONTAGE 6OFT STREET -48- ,g-///}3 3. The 50-foot minimum lot width at the setback has been established in order to somewhat assure a house may be constructed on the lot without much problem. Lots with diverging side lot lines will usually have no problem accommodating a house. However, lots with converging side lot lines may have a problem because the lot becomes nattower towards the rear. The proposed house plans should be checked to see if the house will fit on the lot. The front yard setback will be increased to provide 22 feet between the face of the garage and the back of sidewalk. LOTg ON THIS S~O~ O, TWE CU~E 4. The minimum lot frontage applies primarily to lots which front on a straight street. Lots which front on a curved street will usually have lot frontages that are either greater or less than the minimum lot frontage requirements. The minimum 50 foot lot width at the setback is usually applied to the lots fronting on a curved street. -49- S. The minimum lot frontage of a lot on a cul-de-sac or knuckle is 35 feet. The minimum lot width at the setback line shall be 50 feet and shall be the determinant factor if the lot frontage has to be increased. The purpose of the minimum lot frontage of 35 feet is to allow street parking. If the frontages are too narrow, the driveways would take up all the area for parking. S T R EET .s'.,. MEASURED ALONe S T R E E T ~5? IN M a UeeO ALONe CUL-DE-~ ~' UCKLE z 6. Side lot lines should be 90° or perpendicular to a straight street and radial to a curved street and cul-de-sac. Side lot lines which are not perpendicular or radial are permitted when the lot configurations would be awkward otherwise. The teason for these guidelines is that the resultant lots will be more unifom and regular in shape present a more orderly appearance and a house will usually fit those lots easier than lots .which ~re irregularly shaped. 7. The minimum lot depth is 90 feet. This is increased to ll0 feet for lots fronting or backing up to arterials, majors and collectors. The reason for the increased lot depth is to allow a greater separation between the travel portion of the street and the house. The minimum lot depth is predicated on the standard setback, house depth and rear yard depth and allows some flexibility as to the front setback of the house. LOCAL STREET ARTERIAL, MAJOR OR COLLECTOR STREET LOCAL STREET 8.

Local Drainage Channel or System: A drainage system which collects local runoff from an area of less than lO0 acres and transports water to a lateral or major system. 4. Drainage Channel or System: An open or closed conduit, improved or unimproved, designed for the purpose of collecting and transporting storm water runoff in such manner as to protect public and private property. 5. Drainage Structure: A catch basin, outlet, inlet, headwall, spillway, energy dissipator, junction box, cleanout box, diversion box, etc., in a drainage channel or system. 6. Design Storm: A storm of such magnitude which may be expected to occur once during a specified number of years and resulting in the maximum storm water runoff to be anticipated once during that specified number of years. C. General Responsibility for Construction and Financing of Various Drainage Facilities. When a property is subdivided, the developer is required to accept any drainage which enters his property, to convey tt in appropriate facilities across his property, and to discharge it into the stream into which it would naturally drain. The developer of land through which drainage flows is responsible for the cost of design and construction of drainage facilities~ to include any off-site easements or facilities which may be necessary to accomplish these drainage responsibilities. D. Design Storm. In general, all major drainage channels shall be designed to discharge a 50-year ultimate storm, without static head; lateral channels shall be designed to discharge a lO-year storm without static head at entrances and a 50-year ultimate storm utilizing available head without causing substantial damage to surrounding property; and local channels and drainage facilities within street right of ways shall be designed to discharge a lO-year -69- storm utilizing available head without causing substantial property damage, except that where a sump condition exists and excess runoff has no alternate route, special design shall be required for the protection of property. E. Hydrology. 1. Runoff quantities as set forth or derived from the report prepared by Lawrence, FogS, Florer and Smith titled "A Special Study of Storm Drain Facilities" on file in the office of the Director of Public Works may be used in the design of drainage facilities in Chula Vista. 2.
