A few words of explanation: I was informed as to the date and approximate time of the survey: Therefore, I was able to invite children from `other daycare homes.to.j'oin us.. In this way,•I was able to closely approximate the, number of children"which would be on site at any time:l This number includes my own three school -:aged children, which were all . present in the play yard. Additionally, I planned activities which typically excite the children.and.get them quite wound up. In other words, I attempted to stage a situation with the maximum number of people and the'maximum,amount of noise. Additional activity not mentioned in the report; but which occurred during the noise survey includedltwo Parents entering the play yard to pick up their children and one child,crying when pushed by another child. The report summary explains that the cars on Swallow drowned out any noise made by the children. Without traffic, the sounds of children playing never exceeded 5'S dB, the sound level of two people engaged,in normal conversation. Please include this report in the information which you are compiling on Wonderland'Preschool. Thank you. Sincerely,.

At the time of the survey there were 15 children playing in the backyard. The age range was 1j years old to 17 years old, with 10 children between 1j and 5 years old and 5 school age (two 7 year olds, one 8 year old, one 12 year old and one 17 year old). Activities taking place during the noise survey included group play activities that excited the children such as chasing bubbles, bouncing balls in the center of a large parachute, playing in the sand box and on the playgroundlequipment. Children were laughing and running around. At site #1, I was directly behind the house approximately 20 feet from the chain link fence. Kids playing 45-55 dB(A) Traffic on West Swallow 50 to 60 dB(A) Site #2 - West side of ditch, behind house on Meadowlark Drive (Third house north of West Swallow on Meadowlark Drive) Traffic on West Swallow 46 to 52 dB(A) Children playing 45* to 50 dB(A) * Meter does not measure noise levels below 45 dB, so reading may have been lower than that. Background noises which I could hear, but did not register on noise meter included train, dogs barking, birds in trees along the ditch and wind blowing leaves in the trees. Summary Based on the city noise ordinance of 55 dB(A) from 7 a.m. to 7 p.m. my preliminary noise survey did not find any noise violations. The cars going by on West. Swallow were louder than the children playing. In fact, Thad to wait for a break in traffic to get a noise meter reading of the children playing. The noise survey was conducted under what would be the maximum children present and engaged in active and. boisterous play. Ms. Jacobs indicated a privacy fence was going to be put up along the back, this would further reduce the noise. BOARD OF COUNTY COMMISSIONERS (14Q v,--4L� Courtlyn W. Hotchkiss M. J.
