27.62.050 DENSITY (RESIDENTIAL PD).

The number of dwelling units shall be based on the minimum development standards for the zoning district in which the development is located. If the development is located in a nonresidential zone, R5 minimum development standards shall apply.

27.62.055 LOT SIZE AND WIDTH.

(a) The lot size and width requirements of the underlying zone shall apply unless the proposed development site is over one acre in size and it can be demonstrated that:

(1) A better design will be achieved by not adhering to Zoning Code requirements by:

(A) Preserving and enhancing existing site elements such as, but not limited to, heritage trees, topography, waterways, important historical or architectural resource, views, natural open space and archaeological sites; or

(B) Providing common open space and recreational facilities sufficient to meet the needs of the intended inhabitants; and

(2) Adherence to the requirements of the Zoning Code is not required in order to insure the health, safety, and welfare of inhabitants of the development or adjacent properties.

(b) Regardless of the approved lot size and width, in no case shall the residential planned unit development exceed the unit density development standards of the underlying zone.

27.62.060 SETBACKS AND SPACING BETWEEN BUILDINGS.

(1) Setbacks and Distances Between Buildings Within the Development.

Spacing and distances between principal buildings shall be at least equivalent to that required by the zoning district unless the applicant demonstrates that:

(a) A better or more appropriate design can be achieved by not applying the provision of the zoning district; and

(b) Adherence to the requirements of the zoning district is not required in order to insure health, safety and welfare of the inhabitants of the development.

(2) Peripheral Setbacks.

(a) Generally. Setbacks between any principal building and any peripheral boundary of the development shall be equal to the minimum required setback on the immediately adjacent property unless otherwise provided.

(b) Decreased Setbacks. Decreased setbacks may be allowed where the applicant demonstrates that a better or more appropriate design can be achieved by the allowance of a reduced setback and adherence to the setback requirements of immediately adjacent property is not required in order to insure the health, safety and welfare of inhabitants of the development or the adjacent property.

(c) Increased Setbacks. Setbacks greater than those of the immediately adjacent property may be required where the intensity of development is greater than that of the adjacent property to such an extent that greater peripheral setbacks are needed in order to insure the health, safety and welfare of the inhabitants of the development of the adjacent property.

27.62.070 CIRCULATION AND PARKING.

(1) Major and local streets, the location of all buildings, parking areas, pedestrian ways, and utility easements, shall be designed to promote the public safety, compatibility of uses, and minimization of land use conflicts.

(2) Private streets may serve circulation and parking purposes if designed for fire and police protection, rubbish collection, and lighting and other public services.

(3) Circulation and parking areas shall be separated from recreational areas to facilitate safe vehicular movement. In the design of the circulation and parking plan, priority shall be given to pedestrian access and activity.

(4) Driveways, circulation roadways and parking areas shall be designed to minimize traffic and congestion within the planned unit development, to minimize the amount of paving and to provide reasonable distribution of resident and visitor stalls to minimize walking distances.

(5) Adequate access for fire and other emergency vehicles shall be provided on site.

(6) Parking shall be provided which is equal to that required by Chapter 27.64 of this title, except that those requirements may be increased or decreased where the City Council determines that because of the location of the property with respect to surrounding areas within reasonable walking distance, and/or public transportation, or any other consideration reasonably relating to the need for parking in the development, such increase or decrease is appropriate. Where parking on private streets is unavailable or prohibited due to design or privately-enforced restrictions, parking requirements may be increased.

(7) Legal notices for applications for planned unit development shall specify any reduction in parking which has been requested.

(8) Communal parking areas shall be screened from living areas within the development by landscaping and transitional yards.

(10) Facilities shall be provided for the storage of recreational vehicles, such as boats, campers, and trailers where appropriate.

(11) All streets which are part of the project shall be privately-owned and maintained, and shall provide continuous public access. The hours of public access may be reduced subject to the commission establishing the following findings:
