Landscape Lessons Learned
Landscape Lessons Learned August 4th 2008 Gravel Pave Parking Lots Gravel pave reduces the amount of hard surface at the site, but increases the maintenance of the overall parking lot. Gravel sticks in the tires of parked vehicles and tracks onto the concrete creating a slippery surface. Areas were not meant to be plowed by snow removal vehicles. When plowed the pea gravel gets carried by the snow plow blade. If parking lot is not level or close to level all the pea gravel washes down to the lowest points of the parking lot creating drainage problems and maintenance issues. PSD has tried two of theses parking lots and does not look to continue this idea for the above mentioned reasons. Native/Drought Tolerant Turf 1 2 3 Native turf needs to be isolated from other turf so that irrigation can be applied to specific turf type (picture 1). Plants need to be inside an edge area that keeps mowers and trimmers away from the plant material (picture 2). Application of native or drought tolerant turf works well on tops of hills. Allowing less water to be used to achieve the same green look (picture 3). Native/Drought Tolerant Turf Kinard Junior High has native grasses that are zoned separately from the surrounding grasses and surrounding planting beds. Irrigation can then be specific to the type of crop in the irrigated area. These pictures show the turf being mowed at 2 ½” every week instead of once or twice a season. The savings is realized on the water conservation side, not the mowing maintenance. More xeric or drought tolerant plant selection in these planting beds. All trees in the native area are watered with automatic tree bubblers in preparation for less water because of turf type. Student “Traffic” Patterns Areas where students take the shortest distance between point A and point B. These pictures show a path from the student parking lot to one of the main entrances of Fossil Ridge High School. Student “Traffic” Patterns Before Lunch room traffic at Riffenburgh Elementary Passing period traffic at Boltz Junior High caused these wear patterns between these outside doors. Student “Traffic” Patterns After New sidewalk allows for students to walk around the building without being in the turf. Area by the drive also allows for students to gather while waiting for parent pick up. New colored sidewalks should provide hard surface walk ways for students between outside doors. Bike Collection Areas Bike racks are often an after thought once the school is open. Often the front entrance is where racks are placed or even in the turf due to lack of hard surface space available. Newer sites are being designed with collection points away from main entrances. All new bike rack areas have hard surface and ample room to access both sides of the racks. Playground Transfer Area Progression from first elementary (Zach) to second elementary (Bacon) through final elementary (Bethke). Playground transfer areas have improved drastically from having an issue with student traffic across the turf to not having turf between the building and the playground. Area still looks pleasing with the use of colored concrete instead of turf. Planter Beds In Play Area Three different approaches to the planter 1 2 beds at Bacon (1), Zach (2) and Bethke (3). At Bacon the plantings are still original with large shrubs that can be invasive of the sidewalks and grow into the other plantings. At Zach we changed the plant material to grasses and lilies because these plants are more contained. At Bethke the planting beds are completely surrounded by seat walls to keep the students out of this area. 3 Athletic Field Access Gates Access gates are sometimes an after thought and not as well planned or located as needed. Field drainage needs to be taken into account when deciding a location for large traffic gates. The shortest route to the field might not always be the best, even if it costs a little more up front. Employee Buy In Of Integrated Landscaping As a facilities department the effects of integrated landscaping can be felt for years. Some problems can be addressed by letting the employees state their input prior to building approval. PSD prides itself on learning from previous ideas and maintenance costs associated with new ideas.
