16.24.080 Design toolbox.

A. Design Introduction. The design toolbox provides information about how to meet the requirements of other sections of the LMC and other mandates (e.g., the City of Lacey Stormwater Design Manual), in ways that are consistent with the vision for the Woodland District and the three subdistricts defined in LMC 16.24.010, and mapped on Figure 16.24.010-1, Regulating Plan, Subdistricts. There are three areas of design that are addressed in the design toolbox section: LIDA treatments, street intersection design and street traffic calming design.

1. Low Impact Development Approaches (LIDA). LIDA design options are described in Table 16.24.080-1. A stormwater management and land-development strategy applied at the scale of the block and the scale of the parcel that emphasizes conservation and use of on-site natural features integrated with engineered, small-scale hydrologic controls to more closely mimic predevelopment hydrologic functions.

2. Street and Through Connection Crossings. Table 16.24.080-2, Street and Through Connection Crossing Approaches, describes the type of intersection designs that are required on specific street intersections, and when they are required to be constructed.

3. Traffic Calming Approaches. Table 16.24.080-3, Traffic Calming Approaches, describes the type of traffic calming designs that are required on specific street intersections, and when they are required to be constructed.

Table 16.24.080-1. Low Impact Development Approaches

Urban Mixed Use. Low-impact development approaches (LIDA) should reflect the character of the place. In the most urban areas of the Woodland District, the function of rainwater detention and stormwater re-infiltration should be intense and highly structured. LIDA techniques consistent with this context include green roofs, rainwater harvesting, infiltration planters, permeable paving, and detention vaults.
Urban Mixed-Use LID Approach	Example	Where Permitted
Urban Mixed Use Type A (Street Furnishing Zone and Sidewalk) Site Applicability: For urban sidewalks where there is on-street parking and street furniture. Applicable LID Facilities: Bioretention with raised edge treatments with native and drought tolerant vegetation and street trees are preferred. Permeable paving is the preferred surfacing for sidewalks where feasible. Design Considerations: Designed to accommodate frequent pedestrian traffic between parked cars and retail or service commercial. Vegetated LID facilities are confined to a portion of the furnishings zone of the sidewalk, and are limited in length.		6th Avenue Golf Club Road Pacific Avenue Other streets Through connections Infill block site area
Urban Mixed Use Type B (Curb Extensions/Bulb Outs and Sidewalk) Site Applicability: For urban sidewalks which include curb extensions, such as at corner curb ramps. Applicable LID Facilities: Bioretention in planters with native and drought tolerant vegetation are preferred. Permeable paving is the preferred surfacing for sidewalks where feasible. Rainwater harvesting to manage roof runoff is encouraged. Vegetated roofs are encouraged for roofs that serve as a gathering space.
