(Ord. 82-43 § 1 (part), 1982; Ord. 80-42 (part), 1981).
23.24.030.6 IMPROVEMENT STANDARDS – LOT STANDARDS.
The size, shape, and orientation of lots shall be appropriate to the proposed subdivision location, and to the type of development contemplated. The following principles and standards shall be observed:
(a) The minimum area and dimensions of all lots shall conform to the requirements of the zoning ordinance for the district in which the subdivision is located. Further, they shall be in keeping with the size and arrangement of existing lots in the immediate area, even though this may require a lot size that is greater than the minimum. Exceptions may be considered where physical constraints make cluster developments more appropriate, or in conjunction with specific area plan requirements, or in conjunction with townhouse dwelling developments.
(b) The side lines of lots shall generally be parallel to each other when located along straight streets or approximately radial to the centerline of curved streets. Side lines of lots located on the turnaround for a cul-de-sac shall be approximately radial to the adjacent right-of-way line of the turnaround.
(c) No lot shall have a street frontage of less than thirty-five feet except as may be approved for flag lots and in planned communities, planned developments, condominiums, townhouse dwellings and cluster housing developments.
(d) Corner lots for residential use shall be platted wider than interior lots in order to permit conformance with the required street side yard requirements of the zoning ordinance.
(e) No residential lot shall have an average depth of less than ninety-five feet, except where unusual topographical conditions prevail. Where the rear of a lot is adjacent to a playground, shopping center, industrial tract, or other nonresidential use, or to the right-of-way of a freeway, railroad, or thoroughfare, the lot shall have a minimum lot depth of one hundred and twenty-five feet.
(f) A lot depth greater than twice the lot width shall be avoided wherever possible.
(g) No lot shall be divided by a city-limits line.
(h) No property remnant which does not conform to the requirements of this title shall be allowed in a subdivision, unless it is required for a public utility or facility.
(i) A flag lot may be allowed where warranted by physical conditions of land form, existing lot pattern, or unusual size and shape of parcels. The narrow strip of land connecting the main portion of a flag lot to the street shall be not less than twenty feet wide at any point and shall provide practical vehicular access; but it shall not be used to help satisfy the minimum lot area requirement of the zoning district.
(j) The design of double-frontage lots and lots with excessive street frontage shall be discouraged.
(k) The proposed subdivision should be designed to optimize the use of natural elements, such as solar radiation, wind, and landscaping for heating, cooling, and ventilation both within the subdivision and on adjacent properties.
(1) Examples of passive or natural heating opportunities in subdivision design include design of the size and configuration of lots to permit orientation of a structure in an east-west alignment for southern exposure.
(2) Examples of passive or natural cooling opportunities in subdivision design include design of the size and configuration of lots to permit orientation of a structure to take advantage of shade or prevailing breezes.
(3) In providing for future passive or natural heating or cooling opportunities in the design of a subdivision, consideration shall be given to contour and configuration of the parcel to be divided, to local climate, and to other design and improvement requirements. Such provision shall not result in reducing allowable densities or the percentage of a lot which may be occupied by a building or structure under applicable planning and zoning ordinances.
(4) The requirements of this section do not apply to condominium projects which consist of the subdivision of airspace in an existing building, when no new structures are added.
(5) For the purposes of this section, the term “feasible” means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environmental, social, and technological factors.
(Ord. 2005-15 § 18, 2005: Ord. 81-52 § 1, 1981; Ord. 81-27 § 4, 1981; Ord. 80-42 (part), 1981).
23.24.030.7 IMPROVEMENT STANDARDS – STREET NAMES.
The following principles shall govern the naming of streets:
(1) Names shall be appropriate for street designation. Names which are so similar in spelling or in pronunciation to the names of existing city and/or county streets, as to cause confusion, shall not be accepted.
(2) The words “boulevard,” “street,” “avenue,” or similar words designating a street shall be written in full on the map and shall be subject to approval by the zoning board.
(3) Any street which is a continuation, or an approximate or logical continuation, of any existing dedicated street shall bear the same name.
(4) Where the extension of a street is impractical or impossible because of physical barriers, the streets shall be given different names, even though they may be in the same general alignment.
(5) Any street that forms a portion or a continuation, or an approximate or logical continuation, of any proposed street which has been previously ordered by the city council to be surveyed, named, opened, widened, and improved shall bear the same name as said proposed street.
(6) One of the following designations that most closely reflects the existing or the proposed adjacent land use, or a designation approved by the zoning board, shall be used in naming a street:
Alley A secondary access way.
Avenue, drive, road, street A commercial, industrial, or urban residential street.
Boulevard An arterial street or parkway.
Circle, court, place A residential cul-de-sac or loop street.
Lane, terrace, way A light-use residential street or access drive.
Parkway A street with scenic drive characteristics as defined in this title.
(Ord. 80-42 (part), 1981).
23.24.030.8 IMPROVEMENT STANDARDS – DESIGN CONFORMANCE.
The street design of the subdivision shall relate to the pattern of thoroughfares designated in the General Plan and to any other existing or proposed street designs, as recommended by the zoning board and approved by the city council. Whenever a thoroughfare abuts or traverses a subdivision, it shall be included in the subdivision street design.
(Ord. 80-42 (part), 1981).
23.24.030.9 IMPROVEMENT STANDARDS – STREET PATTERN.
The street pattern of the subdivision shall provide for the most advantageous development of adjoining lots, the neighborhood, and the community; and it shall be designed to carry the ultimate traffic of the subdivision and of any other lands it may serve. The street system shall be designed to save and protect existing trees, wherever possible; and it shall be designed in harmony with the topography. The following principles and regulations shall be observed in the design of street patterns:
(1) The street system shall contain sufficient collector streets and thoroughfares to carry all proposed traffic through the subdivision. Whenever possible, thoroughfares shall be located on the periphery of the subdivision.
(2) Local streets shall be designed to discourage through traffic. Long, straight local streets conducive to high-speed travel shall be avoided. Cul-de-sacs and loop streets shall be used in appropriate locations in residential districts.
(3) The centerlines of local streets, if not in alignment, shall be adjusted by curves to meet or shall be offset at least one hundred and twenty-five feet. Collector streets and thoroughfares may be required to have greater offsets.
(4) Proposed streets shall align with existing streets and extend to the boundary of the subdivision for future continuation into undeveloped lands, when such connections are necessary for the best development of the subdivision and of surrounding lands.
(5) Where a stub-end street extends to the boundary of a subdivision and serves one or more lots or is more than one hundred feet long, the subdividers shall provide either a temporary turnaround or a temporary connection to another street, pending the extension of said street into the adjacent property. It shall be the responsibility of the developer of such adjacent property to replace the temporary turnaround or temporary street connection with a permanent street section, at the time the subject property is developed.
(6) Streets shall be designed to intersect at right angles as nearly as topography and other limiting factors of good design will permit. “T” intersections, rather than “X” and “Y” intersections, shall be used whenever possible.
(7) Reserve strips designed to provide private control of access to streets, easements, or other public ways will not be approved.
(8) Half-streets will not be approved. Boundary streets shall have a right-of-way width of not less than forty feet and shall be improved as specified by the city engineer.
(9) Where provided, alleys shall be fully improved to the standard specifications and shall have proper lighting, as specified by the city engineer.
(Ord. 80-42 (part), 1981).
23.24.030.10 IMPROVEMENT STANDARDS – DESIGN ADJACENT TO THOROUGHFARES.
The design of subdivisions adjacent to thoroughfares shall be as recommended by the General Plan and as determined by the zoning board. The following principles and standards shall be observed:
(1) Street and lot layouts in residential subdivisions shall be designed to minimize the effect of the adjacent thoroughfare traffic.
(2) The number of streets intersecting thoroughfares shall be held to a minimum. Wherever practicable, such intersections shall be spaced not less than one thousand feet apart.
(3) Frontage roads, where required, shall conform to the standards specified herein. Such roads shall enter thoroughfares by means of “bulb” type intersections capable of storing at least two cars between the frontage road and the thoroughfares.
(4) Frontage roads shall be separated from thoroughfares by a permanently landscaped strip, not less than ten feet in width. The subdivider shall plant such parkways with low-maintenance landscaping and shall provide automatic irrigation systems to water all plantings effectively. The subdivider shall maintain all plantings and shall replace any dead or diseased planting material for a period of ninety days from the city council improvement-acceptance date.
(5) Where frontage roads are not required, residential lots abutting a thoroughfare will normally be required to be served by a street paralleling the thoroughfare, at a minimum lot depth of one hundred and twenty-five feet therefrom, or by a series of cul-de-sacs. In such case, a wall or fence or landscaping strip, or a combination thereof, as approved by the director of planning, shall be required at the property lines adjacent to the thoroughfare.
(6) When any lot abuts two streets, one of which is a thoroughfare, the subdivider may be required to execute and deliver to the city an instrument, deemed sufficient by the city attorney, waiving access rights from the lot to the thoroughfare.
(Ord. 80-42 (part), 1981).
23.24.030.11 IMPROVEMENT STANDARDS – GRADES, CURVES, SIGHT DISTANCES.
Grades, curves, and sight distances shall be in accordance with the standard specifications and shall be subject to the approval of the city engineer.
(Ord. 80-42 (part), 1981).
23.24.030.12 IMPROVEMENT STANDARDS – CURBS, SIDEWALKS, PEDESTRIAN AND BICYCLE ACCESS, AND BUS STOPS.
The following principles and standards shall apply to the design and the installation of curbs, sidewalks, and pedestrian ways.
(a) Vertical-type curbs and gutters shall be required in all subdivisions.
(b) Sidewalks shall normally be required on both sides of the street in any subdivision and shall normally be located within the street right-of-way, except as otherwise provided herein.
(c) A paved, or otherwise improved, pedestrian way, not less than ten feet wide may be required, through unusually long blocks or when necessary to provide access to schools, shopping centers, transportation, or other community facilities.
(d) All proposed bikeways shall conform to the design and construction standards contained in the city of Santa Cruz bikeway study. When not located in the public right-of-way, bikeways shall be maintained by the homeowners’ association.
(e) Should the subdivision be on an existing or planned transit route, a bus stop pullout may be required; if so, it shall be designed according to Santa Cruz Metropolitan Transit District specifications. Bicycle-locking facilities shall also be provided at these locations.
(Ord. 82-43 § 1 (part), 1982; Ord. 80-42 (part), 1981).
23.24.030.13 IMPROVEMENT STANDARDS – BASIC STREET STANDARDS.
All streets and thoroughfares shall be platted according to the basic street standards contained herein, except that higher standards may be required where streets are to serve commercial or industrial property, or when dense traffic conditions are predicted.
(a) Divided Thoroughfare. Designed to serve high-volume (four lanes or more) inter- and intra-urban traffic needs, where full or partial control of access and a minimum of intersecting streets are desirable. Adjacent land uses should be located on frontage roads, cul-de-sacs, or back-up lots.
(b) Thoroughfare. Designed to serve high-volume, inter- and intra-city traffic needs and to act as distributors between freeways, other thoroughfares, and major traffic generators. Adjacent land uses should be located on frontage roads, cul-de-sacs, or back-up lots. Thoroughfares should be spaced approximately one mile apart in outer sections of the city, to a few blocks apart in highly built-up, congested areas.
(c) Parkway. Designed as a scenic drive or to connect thoroughfares to local street or public facilities, such as park overlooks, community assembly points, and beaches. A minimum of intersecting streets is desirable. The center median shall be designed to minimize the number of points of cross traffic.
(1) Acceptable Modifications.
Increase from two to six lanes, with a proportional increase in the right-of-way width, as required by the traffic demand.
Reduction of the center median to four feet, where sufficient right-of-way width is unavailable and where left turns are not required.
Sidewalks on side of primary use only, in areas of minimal pedestrian use.
(2) Modifications or Use Prerequisites.
Subdivider’s option, upon recommendation of the zoning board and approval by the city council.
Conformance with standards approved for planned developments (P-D), condominiums, or cluster developments.
(d) Industrial Streets. Designed to serve facilities within industrial areas and to connect such areas with the major street system.
(e) Collector Streets. Designed as connecting traffic facilities between local streets and thoroughfares. Such secondary streets should be spaced one-third to one-half of a mile apart within neighborhoods. They should be arranged to provide service to schools, parks, churches, public facilities, shopping centers, etc., and to discourage through-neighborhood traffic.
(f) Split-Level Collector Streets. Designed as connecting traffic facilities between local streets and thoroughfares, primarily in residential hillside areas where, because of topographical conditions, a standard local street would not be feasible. The right-of-way of a split-level collector street shall include the land between the two sections.
(g) Local Street. Designed to provide direct access to abutting property, primarily in residential districts. Continuity is not necessary. Curvilinear and loop streets may be desirable.
(1) Acceptable Modifications.
Sidewalks may be located on one side of the street if designated crosswalks are provided at regular intervals.
Where a subdivision is part of a planned development or cluster, a system of sidewalks separate from streetside sidewalks may be used to provide access to neighborhood streets from all major areas of a subdivision.
A subdivision may propose private streets when:
The streets are intended for internal circulation only; and
A homeowners’ association is proposed which maintains landscaping, recreation rooms, common space, and streets, etc., or
A homeowners’ association is proposed which maintains at least streets, and has four or fewer units.
Private streets shall be designed for local traffic only and have two travel lanes of at least ten feet each. Ultimate street width shall depend on how the proposed street design accommodates the two travel lanes as well as parking.
Parking provisions for subdivisions with private streets shall comply with the off-street parking regulations of this title. In addition, provision shall be made for two additional parking spaces per unit. This parking can be provided in various ways:
Parking bays removed from the travelways;
Off-street parking within a common area removed from travelways, in close proximity to units served.
On-street parking lanes either on one or both sides of the street, minimum width eight feet;
Driveway approaches may be counted as additional parking, so long as driveway depth is at least twenty feet beyond curb or sidewalk;
Additional parking shall be provided within three hundred feet of the use intended to be served.
(h) Local Hillside Streets. Designed to provide direct access to abutting properties, primarily in residential, designed, hillside areas, where, because of topographical conditions, a standard-width local street would not be practicable.
(1) Acceptable Modifications.
A curb-to-curb width of twenty-eight feet and a right-of-way width of forty-eight feet, in designated hillside areas supporting a density of one dwelling unit an acre (1 DU/Acre) or lower.
A curb-to-curb width of twenty-four feet and a right-of-way width of forty-four feet, in designated hillside areas where parking bays are provided. One such parking bay nine feet by twenty feet shall be required within the right-of-way, in lieu of parallel on-street parking spaces, for each fifty feet of lot frontage, or portion thereof, served by the street. Such parking bays may be located on either or both sides of the street.
Walks on the “use” side only, on a local hillside street providing access to land use on only one of its sides.
Walks, or improved pathways, on only one side of a local hillside street, in areas supporting a density of one dwelling unit an acre (1 DU/Acre) or lower.
No walks in areas supporting a density of one dwelling unit for each three acres (1 DU/3 Acres).
Section 23.24.030.13, subsection (g)(1), Local Streets “Acceptable Modifications” are also “acceptable modifications” to local hillside street standards.
(2) Modification of Use Prerequisites. Subdivider’s option, upon recommendation of the zoning board and approval of the city council.
Conformance with standards approved for planned developments, condominiums, or cluster developments.
(i) Cul-de-Sacs. Designed to facilitate the development of areas where through streets are unnecessary or difficult to develop, to eliminate through traffic, or to serve otherwise unusable or inaccessible land areas. Primarily to be used in residential districts.

23.24.030.15 IMPROVEMENT STANDARDS – HILLSIDE STANDARDS.
Where all or any part of a subdivision has an average cross slope in excess of twelve percent or where, in areas of lesser slope, standard requirements for streets and other improvements would be unduly harmful to unusual or unique natural land features, the zoning board may designate all or part of such lands as “hillside areas.” When a subdivision, or part thereof, is so designated, hillside improvement standards may be applied by the subdivider or may be required by the city council, upon recommendation of the zoning board.
