This consists of approximately four computer runs for each study year (1978 and 1981) using "Noisemap" toenerate Ldn contours (aver- age day-night sound exposure levels in decibels) The runs would include categories such as all operations, all jet and turboprop operations, and other appropriate and interesting categories yet to be decided He also proposed to provide a new approach to the problem of quantifying the noisy single events which have been perceived by residents as most annoying The approach will be to generate on a grid of approximately 100 points around the airport average distributions of single event noise occurances It was explained that the "time-above" contours which the Commission has shown interest in, in the past, do not really give meaningful insight into the noise that annoys people There were several other issues of modelling,which will be discussed with the Noise Sub-Committee, airport users, and tower officials A se- rious problem of incomplete descriptions of some of the aircraft in the original tower data has been mostly eliminated through Lynne and Sally's effort to identify the aircraft by partial N numbers The remaining un- identified aircraft are small percentages of the total and the sensitivity of the contours on how they are modelled can be checked, as Bob Miller pointed out It was stressed that the Hanscom study will be a pioneering one since little has been done previously for relatively small , general aviation air- ports in such depth It may not be possible to answer all questions Paul Showstead (MPA) briefly discussed the need for selective cutting in 4 acres off of runway 11 this spring He hopes to include this work under the ENF already filed for runway 23 Trees up to 3 inches in dia- meter, 20 to 25ft high which presently obscure runway lighting will be removed and their stumps painted with ammonium sulfonate Norm Fredkin reported that the Operation Sub-Committee had met and re- commended that the Commission send a letter to the FAA, urging that the ILS on Runway 29 be installed as soon as possible Using visual aids, Norm gave a`very thorough presentation of landing procedures in IFR conditions, with and without the ILS on 29 Both of the present IFR approaches (a non-precision approach to 29, and a circling approach from 11 to 29) occur at lower altitutes and require larger engine power than would a precision approach using an ILS on 29 It was concluded that both noise and safety would benefit from the installation, and the Commission agreed to send the proposed letter with copies to Bill Coleman and to MAC asking their active support ENVIRONMENTAL AUDIT Specialty Restaurants Corporation 94th Aero Squadron Restaurant Project Description Massport proposes to lease a three acre site to Specialty Restaurants Corporation for the construction of a 12,000 square foot restaurant within the confines of Hanscom Field The restaurant will be located on the North side of Hanscom Field in the Town of Bedford The site is bounded by South Road; a line 750' north of and parallel to the center line of runway 1129 and 100' East of the centerline of taxiway G The restaurant will have 190 seats for dining and 75 seats in the lounge Parking facilities for approxi- mately 170 automobiles will be located adjacent to the restaurant On peak days the restaurant will serve 300-350 lunches and 600-700 dinners Background The restaurant will be a replica of a 100 year old French farmhouse and will have World War II aircraft tied down around it Specialty Res- taurants Corporation owns and operates a large number of "atmosphere" res- taurants around the country The 94th Aero Squadron motif is its most popular These restaurants are located on or adjacent to airfields on lo- cations that provide a view of active runway and as close as possible to runways most heavily used for landing It is important that the restaurant site be removed from other buildings as much as possible to help convey the French farmhouse feeling and to provide sufficient area to allow the tie down of antique aircraft Construction Impacts Site preparation and construction will take approximately eight months During this period, daily truck traffic to and from the site will average less than five trips This traffic will result in insignificant amounts of noise and air pollutants The impact of construction upon water quality is not expected to be significant The project will not require extensive earth moving so the likelihood of erosion will be minimal Operating Impacts Traffic Access to the restaurant will be via South Road from the intersection of Westview Street and Bedford St South Road is a paved, residential street used almost exclusively by residents of South Road and residents living in homes located on tracts of housing which are only accessible from South Road - 2 On an average weekday, the patrons of the restaurant will generate 456 vehicle trips on South Road This estimate was developed using trip genera- tion data developed by the Institute of Traffic Engineers (ITE) An ITE study of "quality restaurants" (i e , turnover time of one hour or more) found that 1 2 vehicle trip ends were generated for each seat on an average weekday and that there were 2 0 people per car on the average for all time periods Number of trip ends is multiplied by two to get vehicle trips Peak hours are from 12-2 on every day except Saturday when peak hours are from 8-9 p.m During a peak lunch, 300-350 vehicle trips on South Road would be generated A peak Saturday evening would generate 600-700 vehi- cle trips on South Road During a peak dinner hour beginning at six and ending at midnight, the increase in traffic attributable to the restaurant would average two cars per minute Traffic would more than likely, actually peak just before and after 8-9 p m -- the peak dinner hour These traffic impacts will be evaluated in a separate study which is currently being prepared_ by a- traffic- consultant Air Quality No known violations of ambient air quality standards exist at Hanscom Field and ambient air quality conditions are not expected to deteriorate as a result of implementation of this project Stack pollutants from the restaurant's heating system and restaurant cooking exhausts will affect air quality to a very minor degree Traffic to and from the site will generate the amounts of air pollutants indicated below TABLE 1 Air Pollutants Generated By Restaurant Traffic* Gram/Day pollutants in average day peak lunch peak dinner grams/mile 456 trips 350 trips 700 trips HC 9 23 4,209 3,231 6,461 CO 135 4 61,742 47,390 94,780 NOx 2 78 1,268 973 1,946 * 1 Based upon official EPA factors for 1982 at 19mph 2 Estimated 1 75 miles per vehicle trip Calculated from intersection of Westview Street and Bedford Street along Westview Street and then South Road to the restaurant site - 3 h Visual The restaurant will be modelled after a French farmhouse c WWII An- tique planes will be tied down outside the restaurant The surrounding area would be landscaped with grassy areas, plants and trees The project will have a positive visual impact on the area Water Quality Waste water generated by the restaurant will be discharged to the U S Air Force Sanitary system During operation, the restaurant will consume approximately 84 gpm of water Water saving devices will be used whenever feasible Conclusions Construction of the restaurant will generate minor environmental im- pacts Once the restaurant is in operation, traffic to and from the restaurant will be the most significant inoact The evaluation of traffic presented in this audit has pointed to the need for additional evaluation of traffic impacts A traffic consultant is currently undertaking further analysis of the traffic impacts associated with this project Associated air quality impacts will be relatively minor, but residents along South Rd will experience readily perceptible increases in traffic during periods of peak operation ML/pl
