CALCULATING A BUDGET WATER USE VALUE Cool ool-season tu turf requ equires app pproxim imatel ely an an aver erage • of 18. 18.696 96” irrigation per year. The a aver erage an annual al “ef effect ective” r rain ainfal all is 7. is 7.44” 44”. • The per acre water requirement t is is 305, 305,645 g gallo allons • per per y year ear. For appr pproximately 79. 79.00 acr acres es o of tu turf, water • requirements are approximately 24, 24,145,955 g 5 gallo allons of water ter an annual ally ly. The actual water applied in 2018 was 39,543, 543,711 g 711 gallo lons, making the existing irrigation system 61.06% e 06% effici cient ent . LOS ALAMOS COUNTY GOLF COURSE

EXPECTED EFFICIENCY OF A NEW IRRIGATION SYSTEM The new irrigation system could apply up to • 30, 30,182, 182,443 43 g gal allons p per er day. This would equate to a theoretical water use • reduction of approximately 23. 23.7% over er 2018 2018 reported ed w water ter usage. LOS ALAMOS COUNTY GOLF COURSE

PROPOSED DESIGN FEATURES Edge-to-edge spray irrigation system, covering • approximately 79. 79.00 acr 00 acres es of turf. Designed for long term maintainability and effective • irrigation control. It is estimated to require approximately 1, 1,500 500 valve- • in-head style golf sprinklers. Proposed irrigation control system will be a • computer-controlled system. LOS ALAMOS COUNTY GOLF COURSE

PROPOSED DESIGN FEATURES Large mainline hydraulic structure capable of • applying the maximum daily evapotranspiration rate of 0. 0.26” 26” within an 8-hour hour water window. All golf sprinklers will be “electric-valve-in-head” • which will enable them to operate individually, allowing for precision control and management when needed. Quick couplers located at greens and tee complexes • facilitates easy access locations to plug in hoses and utilize a high-volume water connection. LOS ALAMOS COUNTY GOLF COURSE

PRELIMINARY COST ESTIMATES Based on a per-sprinkler base cost of $1, $1,250 p 250 per er sprin rinkle ler, plus a “premium” of between 15% and 30% for the likely scenario of perceived “rock- trenching” conditions, the estimated installed cost of the basic golf course irrigation system is expected to range between: $2,157, 157,000 000 ($1,438/per sprinkler) AND $2,437, 437,500 500 ($1,625/per sprinkler) Plus costs of taxes, fees, permits, options, etc. LOS ALAMOS COUNTY GOLF COURSE

ADDITIONAL DESIGN CONSIDERATIONS Turf rf R Reductio ions: There are approximately 3. 3.61 acr 61 acres es of fairway • where some potential areas of turf may be reduced. This could result in a potential annual water • savings of approximately 1, 1,103, 103,17 178 g 8 gal allons. LOS ALAMOS COUNTY GOLF COURSE
