Certain proposed subdivisions ~,vith areas of generally less than 10 per cent slope may have special :!~illside problems, and these may be classified, in part, as hillside sul~division land in order to benefit i'rom the application of these speci;~l standards. In such cases the City Engineer shall determine the applicability of this definition. For purposes oC this definitio:~, gross acreage is the total area of the parcel to be subdivided, or that portion thereof which includes the .prospective lots and their attendant street rights of way and easements. Section 27:2: Desitn Standar~~s for Lots a. General: All lots are to be designed to provide the maximum in safety and human enjoyment while taking advantage of the best natural building sites. b. Grading: 1. Preliminary or tentative grading plans will 'oe required as specified in Section 3 oI' the Subdivision Ordinance of the City or as a part of the conditional approval of the map. Only minimum cuts and fills will be allowed; excess- ive bulldozing and large man-made 'puilding pads will be discouraged. Split level houses are encouraged.) 2. Cut or fill slopes occurring on a property line shall 'oe made a part of the downhill lot. A minimum of 5 feet will be required from the top or toe of any cut or fill to the building foun- dation, unless otherwise approved at the time of the 'auilding permit. 3. A final lot grading plan and quantity estimate may 'pe required as part of the conditional ap- proval and as a part of the tract improvement plans with guarantee by separate performance bond of 100 of cost of such lot grading and construction of driveway approaches for the entire tract. c. Lot Size: The area of each lot shall be sufficient to include the house, together with required setbacks and yards; adequate space for access and off-street parlcing~ and any necessary cuts and fills. d. Off-street Par'.ca.n Where lots have frontages on a roac~.way less than 0 feet wide or on a su'odivision street which is not designed to permit parking at the cur'o, off-street parking shall be provided as follows: 1. Common off-street parking areas to serve several dwelling units shall be pro-sided at the rate of two spaces per dwelling unit, exclusive of gar- age or carport, or 2.

Frontage: All lots shall have frontage on an approved street. Where the principal frontage of a lot is by means of a corridor, such corridor shall be at least 20 feet wide. A lesser width for a corridor may be approved when a 2-foot width would not be practical because of existing permanent structures or topography. However, in all cases the corridor width must be suf- ficient to accommodate a safe driveway of not less than 12 feet of useable width, and if the length of the corridor is over 150 feet the useable width must be at least 18 feet. Where two such corridors are combined, the total access width need not exceed 30 feet if each lot has right of access over the cor- ridor of the adjoining lot and the total useable width is not less than 18 feet. Section 27:3: Desin;n Standard-Streets: a. Desi n Cons~.derations -- The following factors shall be consi erec ~.n~e`design of streets in hillside su'odivisions: 1. Volume of traffic 2. Topography 3.
