3.3 Equipment and Materials
<br />The text box to the right provides a list of equipment and
<br />materials that may be needed to perform maintenance
<br />and inspection activities. The list should be reviewed and
<br />approved by the Silva Cell owner or- operator and should
<br />be modified as of propr at:e for fl e specific: installation.
<br />For instance, if the installation does not have a planter
<br />strip area, weeding equipment may not be needed.
<br />Similarly, if underdrains are not included, vactor, water
<br />jets, and pressure washing equipment may riot be
<br />needed, etc.
<br />3.4 Skills and Staffing
<br />The skills and staff required to inspect and maintain Silva
<br />Cells will vary depending on the size of the installation,
<br />complexity of the system, surface treatment, and site
<br />constraints. Routine maintenance and inspection activities
<br />for the above -ground features will generally be similar to
<br />that of a street tree, planter strip, or sidewalk. Routine
<br />maintenance for the below -ground features will generally
<br />be similar to that of an underdrain or footing drain system.
<br />The Table 2 summarizes the staffing resources that may be
<br />required for routine maintenance and inspection activities:
