_ vith’ GORPORATION OF THE CITY OF PORT cOQUITLAN Re: Pesticides July 9/81 is very difficult to estimate but if we were to have to replace all playing fields once every five years, the cost could be in the order of forty to fifty thousand dollars per year and this would not include the passive parks. I am aware that it is possible to retard the growth of weeds in parks by the use of frequent fertilizing and frequent close mowing. However, to do this we would need to purchase additional mowing equipment and put an additional mowing crew on as our present crew is fully utilized during the summer. I would anticipate that extra fertilizing, irrigation, and mowing costs would run to about $40,000 per year and this would still not solve the problem but only slow it down. dif submitted, i “ LZ FP.E.
