Proposed name change of State Street to Main Street: Public comment will be taken regarding the proposed name change of State Street to Main Street. Mayor introduces the issue. Mayor opens the Public Hearing. Doris Creed, 1337 E. State Street. Feels changing the name of State Street to Main Street has no relationship with the businesses on the street. Ron Marshall, 380 W. State Street. Estimated that to change his office from State Street to Main Street would cost him $500.00 and this is for a one person office. It would be more with an office with more people. This would cost all businesses to change their address. City needs to be careful not to drive the small businesses out of town. We will eventually end up with a town that has no small business. Suggest to table matter tonight and send a questionnaire to all business people that this will affect. Lets leave well enough alone. Pauline Hinman, 404 Ranch Drive, Chamber Executive Board decided that if phased in properly and gently that they would go along with changing the street name. I have had telephone calls from small business people. I'm wondering if the business people should be polled. Chamber will offer their help. ORIGIN'/ I Beckry, owner of the Artisan Gallery, 118 E. State Street. I agree with Ron. The cost for me would be about $500.00. The pro from my stance is that I get phone calls trying to find me in downtown Eagle. They have trouble going from State Street and finding how to mm back onto State Street. I don't know if it will increase my business to have a name change. I can see both sides. Fred Kunkler, 1601 W. State. I have lived with this for 70 years. It's not broke so why change it. Mayor closes the Public Heating. General Council discussion. Sedlacek moves that the Eagle City Council not purse the changing of the name from State Street to Main Street, that it remain State Street. Seconded by Bastian. Discussion.

Firstly, acoustic energy projected at an object can either be deflected away from the object, go over the object or be absorbed by the object. The slain concern here is that sowed which is not deflected away be sufficiently absorbed by the material. The attached sheet provides .he sound absorption coefficient c, various materials The sound absorption coefficient is the measure of the sound -absorptive property of a material and varies with the sound frequency. If a materia has a sound absorption coefficient c_" .65 than this indicates that 65% of the incident acoustical energy which strikes the material is absorbed. Typically, :he sound absorption coefficient Is obtained at frequencies of 125, 250, 530, 1000, 2000 and 4000 Hz. For simplicity, we group the coefficients at these frequencies together and provide a range for each material.

State St. Eagle, ID 83616 Re: Floodplain Impacts from Improvements of Eagle Road and Construction of Eagle Bypass; HECO Project No. 111697 Dear Mark: The following presents the results of the review of Idaho Transportation Department plans for the referenced projects and the applicable Flood Insurance Rate Maps. PURPOSE: Due to the construction of the Eagle Bypass and improvements to Eagle Road, it was determined that review of these plans was necessary to verify that the existing floodplain boundaries and potential flow patterns during a flood were not modified. The review included the areas south of the Eagle Bypass and east of Eagle Road. FINDINGS: Based on review of the plans obtained from ITD, the following items were discovered. 1. The Eagle Bypass was constructed at elevations above the 100 -year floodplain. 2. Eagle Road is being constructed with finish elevations closely matched to the existing road elevations. 3. The structures over the North and South channel of the Boise River indicate the passage of the 100 -year flood and show that the channel is not being constricted by these new structures. WATER • WASTEWATER • SOLID WASTE • PUBLIC UTILITIES • STRUCTURES • PLANNING • STUDIES Page 2 Mark Butler March 31, 1998 CONCLUSIONS: Based on the findings, the following conclusions were reached. ORHN,AL 1. With the construction of the Eagle Bypass, the floodplain boundary is not modified, even though the newly constructed road essentially acts as a levee. It does not modify the floodplain due to culverts constructed under the roadway, in particular the 4 -foot concrete culvert at Ballentine Canal, allowing the water to pass from the south side of the bypass to the north. However, the flooding experienced on the north side will now be from pooled backwater instead of flowing flood waters. 2. With Eagle Road being constructed at existing road elevations, there are no foreseen impacts to the flood elevations depicted on the existing Flood Insurance Rate Map. 3. As indicated on the plans, the new structures allow the passage of the 100 -year flood and even provide an approximate 3 to 4 foot clearance above the base flood elevation. Therefore, no impact on the existing floodplain is expected. Since this review does not indicate any potential modifications to the existing floodplain, a more extensive study is not needed. An updated study of the floodplain is currently underway. This interim evaluation may be modified by additional findings from the restudy. Public hearings will be required when the restudy is completed giving the City ample opportunity to assess and comment on the findings. If you have any questions, please call.

President Lexington Hills Subdivision RE: Vinyl fence facing Hwy 55 Dear Duane: We are providing some information you requested regarding the vinyl fence you are considering for the Lexington Hills Subdivision - the 4 foot high, tan, tongue and groove privacy panel. This product makes an esthetically beautiful fence that will stay looking as good as the day it was installed. It requires no upkeep and will never need painting. It is backed by an industry-leading Lifetime Non -prorated Limited Warranty. Besides being attractive, vinyl is one of the three best sound insulators in fencing materials today. It has an air space in the fencing pieces which help to absorb sound and provides thirty-five to fifty percent absorption rate. Vinyl is a natural insulator, unlike cement, which is the worst fencing product for noise. With fence construction, one can plan on having some sound absorbed by features around the fence such as trees and other landscaping as well as the fence absorbing some of the sound waves. Dirt is the very best insulator of sound. By having the 4 foot berm of dirt and the 4 foot vinyl panel on top, you are providing an excellent barrier for noise. Another factor to consider, is that the vinyl panels will never separate or gap, unlike wood, which has a tendency to warp after time. This fence will always remain solid and remain a barrier against unwanted sound. We are providing some technical data you may want to read concerning noise absorption by different materials. You may contact Lisa Fertis, who is one of Ultraguard's engineers if you have any questions on the vinyl material itself. You can also call me. Jared Bell 1-208-884-0203 Lisa Fertis 1-800-592-6220 Thank you for your consideration. If we can be of any further help, please call. Sin ely, 01,-eX / Jared Bell Operations Manager
