Hardscape Installation Many municipalities consider hardscapes impermeable surfaces even if they are constructed to meet permeable surface guidelines. This categoriza- tion typically subjects these areas to stormwater and other regulations. Once a hardscape design is completed and approved by the client, it should be sub- mitted to the proper authority for approval. Designers who are familiar with a particular area often know local codes and incorporate this into their design. The installer or contractor may apply for permits once the design is approved. Scheduling and Site Access Effi cient scheduling and defi ned access to a site helps ensure a smoother work fl ow. The project manager or job site coordinator must schedule employ- ees, tool and equipment delivery, irrigation installation, and the delivery of both plant and hardscape materials. The coordinator must also anticipate site challenges, changes in weather, and changes made due to the client’s prefer- ences, and work additional time into the schedule. See Figure 15-23. Existing landscape can be disrupted when new components are being installed. Defi ning site access, delivery pathways, and staging areas before the job begins will help minimize damage to other areas. Damage may also be limited by installing silt fences or plastic tape to indicate restricted areas and borders. Special attention should be paid to plants, such as existing trees, that will be incorporated into a design. The roots must be protected from excava- tion work and traffi c across the canopy should be limited to prevent soil com- paction and ensuing health issues. Safety First All equipment must be transported to and from worksites using transport equipment, such as a trailer. When loading or unloading, check the attachment to the tow vehicle and ensure ramps have enough support to prevent raising of the tow vehicle when the equipment enters or exits the trailer.
