The city may waive <br /> this requirement in lieu of a cash escrow or letter of credit equal to 150 percent of the cost to install the <br /> required buffer. <br /> (e) The city-may allow the disturbance of an existing buffer area during the course of <br /> construction activity. This disturbance must be kept to a minimum, soils must be decompacted to a level <br /> that will accommodate root growth, and the buffer area must be re-established as required by the city. <br /> � The city will determine the amount of allowable disturbance. The city may require a cash escrow or letter <br /> of credit equal to 150 percent of the cost to re-establish the buffer to its original condition. <br /> (fl The city may require buffer area planting and maintenance when the city determines that <br /> there is inadequate vegetation in the buffer area to meet the intent of this section. The city may require a <br /> cash escrow or letter of credit equal to 150 percent of the estimated cost of the vegetation and <br /> installation.
