Median Planting Design intent –a grid planting of early, mid and late blooming plants to generate year-round interest. Implementation –has followed the current design standard, but establishment and maintenance has varied by development and homeowner’s association. Maintenance –can be challenging to weed if the person doesn’t know what each plant looks like.

(Changes Character & Site Lines of street) This is a more acceptable option, however the cost of replacing trees if they are not watered/irrigated is costly and labor intensive Irrigation 1st year and during drought Grid-Planting of Grasses and Plants (Consistent Multi-Season Interest) This would require contracting a gardener. Too time consuming, labor intensive and costly Block-Planting of Grasses and Plants (Easier Maintenance) In looking for cost and time saving for our department I see too much time in weeding, cutting and disposing of the grass Maintenance Turf Grass the Entire Median This would be acceptable but if not irrigated it will likely brown up leading to complaints Mow Strip Around the Median Perimeter Wood Mulch Not interested, rain can wash it out, weeds develop, it would need replacement Rock Mulch This would be an acceptable option. However dirt and leaves can fill the rock requiring weeding, cleaning or replacement in future WORKSHOP #1 –MAINTENANCE –PUBLIC WORKS FEEDBACK WORKSHOP #1 –FOUR DESIGN OPTIONS 1.Turf only 2.Turf with ornamental trees 3.Turf plus some ornamental trees plus perennial block plantings (illustrated in sketch plans) 4.All perennial block plantings. •Bring back the estimated maintenance costs associated with each of the four options. •No design direction given without understanding of maintenance costs.
