17.34.040 Design criteria.

The following design elements shall be utilized by the applicant when preparing development proposals and shall be utilized by the DRB and the director when reviewing a development application requiring review per MCMC 17.34.020. When specific design guidelines have been adopted for an area or site as part of a specific development approval, those guidelines shall be utilized in conjunction with design elements listed below. For example, development in the planned community business zone district shall also be subject to the town center design guidelines as adopted in city council Ordinance No. 97-404, as amended.

A. Site Design. The following design elements shall be applied to all projects:

1. Site Design Layout.

a. Sites shall be developed in a coordinated manner to complement the natural topography and drainage, and adjacent structures through building placement, architecture and size/mass.

b. Whenever possible, buildings on the same site shall be designed to enhance safe and convenient pedestrian access between buildings including plazas, courtyards, pocket parks, and other pedestrian use areas connected by clearly marked walkways.

c. Where appropriate, sites shall incorporate transit-compatible designs. “Transit compatibility” means designs that are pedestrian oriented, provide safe and convenient access to transit facilities, and foster efficient transit service.

d. Where appropriate, sites shall be designed to provide vehicular and pedestrian connections to adjacent sites.

e. Private open space shall be incorporated into attached single-family and multi-family residential projects in accordance with MCMC 17.22.060.

f. The use of LID best management practices is required whenever site and soil conditions make it feasible, including pedestrian facilities such as trails and sidewalks. LID best management practices include, but are not limited to, minimizing impervious surfaces, designing on-site LID stormwater management facilities, and retaining native vegetation.

2. Parking Lot Design and Screening.

a. Project design shall avoid the appearance of domination by automobiles. Positive methods to achieve this concept include:

i. Orienting buildings to fronting streets and placing parking at the rear and/or sides;

ii. Designing the required parking area into smaller, discrete, connected lots rather than large, single-use lots;

iii. Designing parking areas to be partially screened from view from adjacent streets and building occupants. Screening can be accomplished through a number of methods including:

(A) Orienting buildings away from parking areas;

(B) Placing buildings between streets and parking lots;

(C) Using extensive landscape screening, berms, and architecturally treated walls that also allow visibility to provide adequate safety and surveillance of the parking areas.

iv. The use of LID best management practices in parking lots is required whenever site and soil conditions make it feasible. Such BMPs include, but are not limited to, permeable surfacing materials and integrating LID stormwater management facilities into the required landscaping.

3. Tree Preservation.

a. Project design shall maximize the preservation of existing significant tree stands and significant individual trees, especially on slopes, street frontages, and on the perimeter of the site.

b. Project design shall incorporate existing natural vegetation into the site design wherever possible.

4. Storm Drainage.

a. Open stormwater facilities (i.e., ponds and bioswales) visible from public areas shall be designed as site amenities and shall provide a natural appearance through layout, design, and landscape treatment. If fencing is determined to be necessary by the city, it shall be installed in accordance with MCMC 17.22.040 and public works policies, and be obscured with landscaping.

b. Stormwater facilities (whether open facilities or vaults) shall be located outside roadway buffers/cutting preserves unless there is no other feasible alternative and the facilities do not compromise the purpose and function of the roadway buffer/cutting preserve. In such cases, the facility may only be located in the outer portion of the roadway buffer/cutting preserve.

c. Where located under areas to be landscaped, underground stormwater vaults shall have adequate soil cover to support the approved landscape plan. The soil shall be of sufficient quality to properly support vegetation.

d. Stormwater bioretention facilities that are integrated into interior landscape areas within parking lots, and that meet area and landscaping requirements may be counted toward the interior parking lot landscape requirements.

5. Vehicular Entrances.

a. Vehicular entrances shall be designed to welcome residents, customers, and visitors. Gated entrances on public right-of-way are prohibited. Gated entrances on private roads are strongly discouraged.
