A copy of that earlier letter dated December 11, 2000 is attached to this letter for ease of reference. In subsequent telephone conversations you indicated that the City would likt to have supporting documentation for the fixture unit calculations cited in the referenced letter, This letter transmits the requested calculations. Attached is a letter dated January 18, 2001 from Mr. Matthew Hicks of Swoboda Engineering, the mechanical/plumbing consultant for the project. Mr. Hicks' letter contains a table summarizing the types and number of fixture units (FU) employed in the calculation of the total F'U count of 1,343 FUs. That total FU count was used to determine the peak domestic water flow in gallons per minute (gpm} for tlxe proposed hotel development. The peak domestic water flow was determined using the total FU count along with Table II -WATER DEMAND BASED ON FIXTURE UNITS {Page 4-7) of the draft joint Bryan/College Station ' Destgrt Manual for Streets and Alleys, Storm Drairra~e, Domestic Water, and Sanitary Sewer (revised 1/29/98), and was also determined using a similar Figure F102 in the Standard Building Code. A pedk domestic water flow of 251 gpm was calculated and is indicated both in Mr. Hicks letter and the CSC letter,of December 11, 2000. We trust that this prcsdntarion~~~and explanation of the calculations used to determine the peak domestic water flow meets the City's re uirernants. Please do not hesitate to contact us should any questions arise or if additional supporti~tg do~ct~tnentation is necessary. ;~ ~I: ;, -- 3407 Tabor Road Phone {878) 778.2810 6ryan.

(CSC) for the proposed Marriott Cc in College Station, ?axes. In a telephone conversation of December 1, 2000, the project architect, Mr. Payne & Associates, telephoned to inform us that some of the domestic wa1 t17c above-referenced project should be revised based upon newly develo flows were estimated for both "normal" domestic demand and for irrigati were presented in tabular form on Sheet C-1 of the site drawings that have City of College Station for review, ed by CSC Engineering c~ at Wood Creek Development Ebert L. Payne, AIA of R. L. flows estimated by CSC for j information. Those water flow. The estimated flows •eady been submitted to the Basically, the revised estimates in the water demand are required because more extensive design work has been performed to better define the water demands for the project. For example, at the time that the site drawings were submitted for, review, no detailed design of the irrigation water system had been performed. Therefore, CSC based the estimate of maximum irrigation water demand on similarly sized previous projects. A maximum irrigation water demand of 27.8 gallons per minute (gpm) was estimated. However, as Mr. Payne has informed us, a more extensive landscape design for the project has since been undertaken. Analyses performed as part of the new design indicated that a larger maximum irrigation water demand water would be appropriate. The new increased irrigation water demand was determined to be approximately 75 gpm. Similarly, the normal domestic water demands should be revised. The normal domestic water demands computed by CSC were based upon the land use determination method outlined in the draft joint Bryart/College Station Design Manual for Streets and Alleys, Storer Drainage, Domestic Water, and Sanitary Sewer (revised 1/29/98), hereinafter referenced as Joint Design Manual (Method 2 -Land Use Determination {Page 4-8]). However, as pointed out by Mr. Payne, the mechanical/plumbing engineer for the project, Mr. Paul M. Swoboda, P.E. of Swoboda Engineering, also calculated the water demand for the proposed building using the Fixture Count Determination (Method 1 -Fixture Count Determination of the Joint Design Manual). As you are aware, the Fixtwe Count Determination method is based upon a specific count of the plumbing fixtures in a building and should produce a more accurate determination of water demand than the more general Land Use Method. Mr. Swoboda computed that the maximum domestic water demand would be 25 i gpm, as summariud along with other water demands in tabular form on drawin P3.4. 3407 Tabor Ro+~d P1ion® (9T9} 776-28i 0 Bryan, Texas 77908 ~ 1`ax (879) 778-0820 01f18f2001 15:09 409-778-0820 CSC ENG & EN'J PAGE 07 $ .
