Chevak is also known as New Chevak because residents inhabited another village called Chevak before 1950. "Old" Chevak, on the north bank of the Keoklevik River, 9 miles east of Hooper Bay, was abandoned because of flooding from high storm tides. The mame Chevak refers to "a _ connecting slough" on which "Old" Chevak was situated. New Chevak became the site of a post office in 1951. The new site was first reported by the U.S. Coast and Geodetic Survey in 1948. es Regional Educational Attendance Areas 2-Bering Strait REAA Schoo! District 3-Lower Yukon School District 4-Lower Kuskokwim School Oistrict 5-Kuspuk School District 11-Iditarod Area Schoo! District ——-- —— Native Regions! Corporation Boundaries POPULATION: The population of Chevak has been increasing slowly but steadily since 1950 when census’ statistics revealed a resident population of 230. By 1960, there were 315 residents; by 1970, 387. By 1979, there were 488 residents. The Inventory of Rural Sanitation Services done in April of 1984 estimates 550 residents. ECONOMY : Employment in- Chevak is at its peak in the summer months, with seasonal firefighting for the Bureau of Land Management (BLM) and summer construction projects. The city usually hires an additional 5-10 people in the summer ffor city improvement and construction programs. The vilage corporation, the Chevak Company, is a viable economic force in the community. In addition, some residents sell their handicrafts (grass baskets, kuspuks, dolls, masks and ivory carvings) to the Native corporation store and to stores in Anchorage, GOVERNMENT: Chevak was incorporated as a second class city in 1967. The city has both a mayor and city administrator. The mayor is selected from the 7-member city council. Under authority granted to second class cities, Chevak levies a 2% sales tax to finance community services, and can assume diverse powers under state law. Chevak is a participant in the State of Alaska's revenue sharing program where communities are eligible to receive financial assistance for certain public services with funds allocated on a per capita basis. TRANSPORTATION: Chevak's location near the Bering Sea_ renders the city subject to heavy winds and rains which sometimes preclude air access to the city. In addition, the 2,300-foot dirt airstrip is usually closed down for a month each year during break-up, There is a public domain seaplane base on the Ninglikfak River. Groceries are shipped air freight from Anchorage to Chevak. Commercial air services provide regularly scheduled flights from Bethel to Chevak Monday-Saturday of each week, In the winter months there is a heavy reliance on the snowmachines in the city for transportation to nearby villages. There are no roads connecting Chevak with other population centers in the region. LAND OWNERSHIP: Pursuant to the Alaska Native Claims Settlement Act (ANCSA) of 1971, the Chevak village corporation was entitled to select 138,240 acres of federal land (equivalent to 6 townships). Chevak has a federal townsite. The townsite patent (U.S>S> 5023, on 75.25 acres of land) was issued to the BLM Townsite Trustee on April 30, 1974. The Trustee, in turn, has since deeded occupied parcels to residents and other vacant subdivided lots to the city. As Chevak is within the bounds of the Clarence Rhode National Wildlife Refuge, the village corporation could not select more than 69,230 acres (equivalent to 3 townships) of the land from the refuge. Other identified lands in Chevak include a 3.77 acre withdrawal in 1964 for BIA school purposes. Land was also withdrawn for an Alaska National Guard Armory site. CLIMATE: Chevak has a maritime climate, Temperatures range from between -25 degrees F and 79 degrees F (Cape Romanzof data). The snow depth on the tundra averages between 2-1/2 and 3 feet with an average of 60 inches of snowfall per year for Chevak. Freeze-up occurs at the end of October; break-up occurs in June. SCHOOLS: Chevak schools come under the jurisdiction of the Bureau of Indian Affairs (BIA). The Chevak Day School’ serves grades K-12 with an elementary and a high school program. Fifteen teachers and teachers aides instruct students in 7 classrooms. The facility, built in 1976, includes a maintenance building and shop, warehouses, utility buildings and teachers' quarters. The City of Chevak is currently attempting to gain control of the school when the BIA withdraws in June of 1985. Should this fail the school will be run by the Lower Yukon School District. OTHER STRUCTURES: Chevak has a large Native store which sells food and clothing and operates a fast food snack bar. There are 4 other stores in the city, including a combination hardware store and shop. The pool hall building is a recreation center for meetings, movies and disco dances and has a snack bar. There is also a traditional council building, community hall, city offices, a post office, Catholic Church, laundromat, clinic, armory and Fish and Wildlife building. ELECTRICITY AND HEAT: The Alaska Village Electric Cooperative (AVEC) provides Chevak with electric power with 3 generators: 350-kw, 300-kw and 160 kw. All occupied structures in the city are hooked up to the system. There are 2 standby generators at the school, each 100-kw. The system appears to be adequate to meet present consumer needs. Fuel oil is shipped by barge during the summer and stored in bulk storage tanks with a total capacity of about 375,000 gallons. In 1983 AVEC paid on the average $1.54/gallon and the BIA School paid $1.44/gallon in 1984.

BUILDING NAME: School Central Boiler Plant OWNER: Bureau Indian Affairs Current Use: BIA School Utility Building Type of Construction: Wood siding, metal roof, piling foundation Size: Approximately 2,000 Square Feet (Boilers provide heat for 28,000 sq. ft. of School Buildings) General Condition: Good Estimated Annual Fuel Oil Consumption: Included with main school Type of Heating System: Two oil fired boilers Method of Waste Heat System Connection: Direct connect to boiler return piping. No heat exchanger. Plans for Future Building Use: See Main School Building CHEVAK HEAT RECOVERY CONCEPTS Concept A: There is sufficient room in the AVEC Butler Building to locate the new heat recovery equipment and district heating pumps. Remote radiators can be mounted outside of Butler Building. Cooling manifold piping can be run from remote generator module to the AVEC Butler Building in the new utiliduct. District heating piping would run to main school building and central boiler building. Arctic pipe would be routed to main school building in new above ground utiliduct extending from AVEC plant to main school foundation, Once under school the arctic pipe would extend through piling foundation to connect with existing utilidor. Once inside existing utilidor pipe would change to standard pipe with wrap type insulation installed inside existing vapor barrier and insulation, Heating piping would extend in existing utilidor to central boiler building. The district heating system would penetrate boiler building floor and connect directly to boiler return piping. For main school building one set of lines would branch off arctic mains and penetrate classroom area floor in fan room access area. A coil would be placed in ductwork and piping would be run in attic space above corridor to fan room at opposite end of building where another coil would be installed in ductwork, Another branch off district heating lines would penetrate gym floor in corner and piping would extend up inside gym wall to two new vertical unit heaters at gym ceiling. Conclusion: No other alternatives were considered since the school is capable of using all the waste heat produced by the Power Plant. The short Payback figure makes this installation economically justified. CHEVAK 1983 WASTE HEAT PROFILE JAN. FEB. MAR. APR MAY JUN JUL. AUG. SEP. oct. NOV. DEC.
