Infill Design Standards. Property that is eligible for infill residential development pursuant to Section 14.46.210 shall adhere to the following administrative design standards. While creativity and variation in architectural design are encouraged, the purpose of these requirements is to ensure compatibility of infill development with the character of nearby existing residential structures.
(1)
Building orientation on infill lots shall match the predominant orientation of other buildings along the street frontage to match the neighborhood character. Multiplexes may have one unit face the street to meet this design standard.
(2)
Parking. Infill developments shall comply with all parking standards pursuant to Chapter 14.72 except as specifically modified by this chapter.
(i)
Parking may be consolidated for infill projects. Parking lots can be attached to individual lots, in common easements or set aside in a separate tract.
(ii)
For single-family and townhome projects, the access and off-street parking shall be like the predominant character for existing development along the street frontage; however, a central parking lot at the rear or side of the development would be allowed.
(iii)
For stacked apartment style projects, the primary vehicular access and off-street parking are preferred to be located to the rear or side of the proposed structures.
(iv)
For garden/courtyard style apartments the parking must be on the side or rear of the development.
(3)
Landscaping shall be provided along the perimeter of the development and parking lots to soften the transition between new and existing dwelling units when the new dwellings are different than the adjacent existing land use.
(i)
Attached dwelling units, including townhomes, stacked apartments and garden/courtyards shall provide a Type B screen as described in Section 14.76.040.
(ii)
Detached single-family infill projects are exempt from buffer landscaping adjacent to other single-family zoning districts.
(4)
Integration with Natural Amenities. Natural amenities (views, mature trees, creeks, rock outcrops, and other similar features) should be preserved and integrated with the development to the maximum extent feasible. Clustering of lots/units and adjusting roadway configuration to integrate these features are encouraged to achieve these goals. Access and visibility to these natural amenities are encouraged.
(5)
Horizontal building facades longer than 25 feet, or the width of individual attached units, shall be treated to reduce building mass and visual bulk using elements described in the Lake Stevens Design Guidelines for blank wall treatments.
(6)
Attached dwelling units shall be design reviewed using the Multifamily Chapter of the Lake Stevens Design Guidelines.
(7)
Additional Requirements for Garden/Courtyard Apartments.
