(§ I, Ord. 406-C.S., eff. May 23, 1984)

Development regulations in the R-M District shall be as follows:

(a)

In the R-M District, for the purposes of determining the maximum total number of dwelling units permissible on any parcel, the following system shall be used: the total parcel shall be compared against the criteria of this section in the order listed. Any segment of a parcel to which a criterion first applies shall be allowed a maximum accumulation of such density. Once considered under a criterion, a segment of the parcel shall not be considered under subsequent criteria. When the applicable criteria have been determined for each of the areas, any portion of the parcel which has not yet been assigned a maximum density accumulation shall be assigned a density of one dwelling unit per five (5) acres. The sum of densities accrued under all applicable categories shall constitute the maximum density of development permissible:

(1)

On lands falling within a 100-year flood plain as defined by the United States Geological Survey, dwelling units may be accumulated at a maximum of one unit per forty (40) acres. Where previous actions have eliminated such flood areas, the provisions of this subsection shall not apply;

(2)

For remote lands, defined as those lands over one mile from an existing all-weather through public road, the density accumulation shall be limited to one dwelling unit per forty (40) acres;

(3)

For areas within any of the three (3) least stable categories (categories V, VI, and L) as shown on the United States Geological Survey Map MF 360, "Landslide Susceptibility in San Mateo County," density accumulation shall be limited to one dwelling unit per forty (40) acres;

(4)

All areas located within the rift zone or zone of fractured rock of an active fault as defined by the United States Geological Survey Map MF 355, "Active Faults, Probably Active Faults, and Associated Fracture Zones in San Mateo County," shall be limited to a maximum density accumulation of one dwelling unit per forty (40) acres; and

(5)

That portion of a parcel which has a slope in excess of fifty (50%) percent shall have density accumulation limited to one dwelling unit per forty (40) acres; that portion of a parcel having a slope in excess of thirty (30%) percent but not exceeding fifty (50%) percent shall have density accumulation limited to one dwelling unit per twenty (20) acres; and that portion of a parcel having a slope in excess of fifteen (15%) percent but not exceeding thirty (30%) percent shall have density accumulation limited to one dwelling unit per ten (10) acres. Slope shall be calculated according to the formula in the Hillside Preservation District (HPD);

(b)

Minimum lot size: five (5) acres;

(b)

Minimum front yard setback: fifty (50′) feet;

(d)

Minimum side and rear yards: twenty (20′) feet; and

(e)

Maximum height: thirty-five (35′) feet.
