In a planned development district, no primary, accessory or conditional use is permitted outright. All uses in a planned development district are conditional upon approval of the Leavenworth hearing examiner, in accordance with the provisions of this chapter, which provisions shall constitute the basis for and become the zoning requirements of the particular planned development district.

D. Provision for affordable housing;
E. Diversification of housing types and sizes. [Ord. 1588 § 1 (Att. A), 2019; Ord. 551 § 28.110(10), 1976; Ord. 531 § 1, 1973.]
18.40.030 Perimeter transition requirements.
All planned development projects shall provide a perimeter transition between single-family residential and commercial uses. The intent shall be to provide a visual break in land uses and separate uses between public spaces and private residential. The perimeter transition shall be no less than five feet and may include:
A. Additional or improved relationship of open spaces; or
B. Additional public facilities, such as pedestrian walks, nonmotorized travel (including bike lanes), alley development, trails, one-way access, traffic circulation facilities and/or public access to lakes and streams; or
C. Preservation of natural assets, such as historic land, parks, or streams. [Ord. 1588 § 1 (Att. A), 2019; Ord. 551 § 28.110(15), 1976; Ord. 531 § 1, 1973.]
18.40.040 Project scope.
Planned development projects shall be complete developments on at least a 6,000-square-foot site for affordable housing or on at least a 24,000-square-foot site for other planned developments, and may be required to include facilities such as paved streets, curbs, sidewalks, street lights, drainage, sanitary sewers, water, underground power lines, landscaping and off-street parking, subject to the requirements of the Leavenworth Municipal Code or the hearing examiner. [Ord. 1588 § 1 (Att. A), 2019.]

18.40.060 Residential project requirements – Minimum requirements.
A. Maximum Density. The maximum density may be increased to twice the underlying zoning.
B. Minimum Lot Size. Lot size for single-family and duplex residential structures shall be no less than 3,000 square feet. Lot sizes for affordable housing may be reduced to 1,500 square feet for affordable housing components. Lot size for multifamily structures shall not be defined.
C. Minimum Setback Distances. The applicant may propose residential minimum requirements for setbacks, except perimeter setbacks shall meet the underlying zoning district.
D. Maximum Height Requirements. Height shall be consistent with the underlying zoning.
E. Maximum Lot Coverage. Maximum lot coverage shall be 50 percent for all residential and duplex building lots and 75 percent for multifamily lots.
F. Sites two acres or greater shall provide at least 10 percent open space, in addition to yard requirements.
G. Parking. One parking space shall be provided for each dwelling unit under 1,500 square feet, and two parking spaces for each dwelling unit greater than 1,500 square feet.

18.40.070 Multiple-use project requirements.
Any planned development project containing combinations of residential, commercial, or recreational uses may be known as a multiple-use project, and shall bear the following relationships to the zoning districts in which it is proposed:
A. In any district, projects shall include:
1. Uses. The principal use or uses proposed in a multiple-use project shall be consistent with the underlying zoning.
2. Parking. For all mixed-use development, shared parking is encouraged. If proposing shared parking, it shall be demonstrated to be maintained for the life of the project by a recorded agreement.
3. Height. Height shall be consistent with the underlying zoning.
B. In the residential districts, which abut other residential districts, multiple-use projects which include residential use shall:
1. Limit land area of nonresidential uses to ten percent of the gross area of the development;
2. Limit nonresidential use to those business facilities which, in size and service, can be related principally to the project; e.g., grocery, drug, and specialty shops, or professional offices. In no case shall transient uses be permitted in residential planned developments. Such uses should be in ground floor locations and in buildings comparable in size, character, and architectural style with the project buildings;
3. Multifamily units shall be in character and of similar architectural style to the single-family buildings of the project;
4. Nonresidential uses permitted as a part of a planned development project in a low density residential area shall not be designed to dominate surrounding residential uses by incorporating oversized advertising signs, intense lighting, increased building height, or other devices which focus attention on location.
C. In residential districts located in transitional areas immediately abutting and adjoining nonresidentially zoned property, multiple-use projects which include residential use shall:
1. Orient nonresidential uses and their automobile circulation and parking towards the adjoining nonresidential district;
2. Limit commercial nonresidential uses to ground floor locations;
3. Provide residential uses on all perimeters adjoining residential districts. [Ord. 1588 § 1 (Att. A), 2019; Ord. 551 § 28.110(35), 1976; Ord. 531 § 1, 1973. Formerly 18.40.090.]
18.40.080 Approval – Conditions.
The granting of approval of a planned development district constitutes an amendment to the zoning map, and must comply with the provisions set forth in the Leavenworth comprehensive plan and Leavenworth zoning ordinance. [Ord. 1588 § 1 (Att. A), 2019; Ord. 1203 § 20, 2003; Ord. 551 § 28.120(10), 1976; Ord. 531 § 1, 1973. Formerly 18.40.100.]
