Compliance with Chapter 12.116 BGMC, Transportation Standards, is also required. Lots shall be of sufficient area, width and length to satisfy zoning requirements. (Ord. 04-023 § 8, 2004: Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.020 Protective improvements required for topographical hazards.
Land on which exist any topographical conditions hazardous to the safety or general welfare of persons or property in or on a proposed subdivision shall not be subdivided unless the construction of protective improvements will eliminate the hazards, or unless land subject to hazard is reserved for such uses as will not expose persons or property to the hazard. Protective improvements shall be clearly noted on the final plat or short plat as applicable. (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.030 Continuation of existing streets.
Existing streets adjacent to the land proposed for subdivision shall be continued in conformance with the standards of Chapter 12.116 BGMC (Transportation Standards). (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.040 Street jogs.

16.125.050 General street design requirements.
Streets shall meet all applicable public and private street standards specified in Chapter 12.116 BGMC. In addition, streets shall conform to engineering standards as approved by the city engineer relative to street grades, horizontal curvature, tangents between reverse curves, vertical alignments, and curbline radii. (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.060 Blocks.
Blocks shall be so designed as to assure traffic safety and ease of traffic control and circulation. Blocks shall be wide enough to allow for two tiers of lots unless the topography or other factors preclude them. (Ord. 04-023 § 9, 2004: Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.070 Lot access requirements and restrictions.
Every lot shall contain the minimum frontage on a public or private street as required by the applicable section of BGMC Title 17. Lots adjacent to a street which has been designated as an arterial by the city council shall be provided with access other than the arterial, unless a specific exemption is granted to this requirement. The plat of a subdivision containing lots adjacent to a designated arterial shall not be approved unless the plat recites a waiver of the right of direct access to the arterial, for example, a ten-foot-wide no-access easement. (Ord. 04-023 § 10, 2004: Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995
16.125.080 Lot line angles.
Where practicable, side lot lines shall be straight lines running at or near right angles to the street upon which the lots front. Side lot lines on curved streets should run at or near radially to the curve. (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.090 Lot size and width requirements.
Lots shall meet the lot area and width requirements of BGMC Title 17. (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.100 Double and reverse frontage lots.
Double frontage lots and reverse frontage lots are prohibited, except where essential to provide separation of residential development from railways, limited access highways, natural resources or commercial and industrial activities or through an approved modification consistent with the requirement of Chapter 16.135 BGMC. This standard is intended to provide building orientation to streets and avoid fencing along street yards. When double- or reverse-frontage lots are developed, fencing along street yards shall be set back behind a landscaped parkway of at least twenty feet in width which is located between the street and property line. Landscape plantings shall include a combination of trees and evergreen shrubs which, upon maturity, adequately screen the fencing. Landscaping shall be low maintenance and after establishment shall not require irrigation. A landscape plan shall be required, in compliance with this section, for all double- and reverse-frontage lots that are approved. All required plantings and irrigation, as required, shall be installed prior to occupancy of the structures they are providing screening for. Alley access and corner lots are permitted by this code, and do not constitute “double-frontage” or “reverse-frontage” lots. (Ord. 04-023 § 11, 2004: Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.110 Flag lots.
Flag lots are discouraged, but, if designed with the required lot size and lot width at the regulatory front setback line, may be allowed where topography makes standard design or more frontage impossible or impractical. Where such flag lots are allowed, the street frontage of each lot shall be as required by BGMC 17.106.030, Table 17.106-2, and the lot access shall not be more than two hundred feet long. Not more than two flag lots shall abut each other. (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
16.125.120 Easements.
Easements for drainage channels and drainageways, electric, telephone, water, sanitary sewer, gas and similar utilities, alleys and pedestrian access shall be provided as determined by the city engineer and the planning director, as appropriate. Easements shall be of sufficient widths to assure that the same may be maintained and improved. (Ord. 99-008 § 1(F) (part), 1999; Ord. 99-004 § 2 (part), 1999: Ord. 95-769 § 4 (part), 1995)
