Does the building design meet the requirements of the Design Corridor? No plans have been available for public viewing. Response: Yes. 2. I would like to see the math explained for the estimated 13,600 cubic yards of fill dirt required. My estimate is closer to 20,000 cubic yards. How many dump truck trips will be required and what route will the tracks take? Response: Using estimated 13,600 cy of fill, assuming 18 cy per truck load, about 755 trips will be required. This will take about 1 to 2 weeks to complete. The earthwork volume was determined using AutoCAD Civil 3D computer program. The program creates a 3D surface model of the site prior to grading and compares it to a 3D surface model of the site after grading is complete. Unfortunately, other than the output, there is no “calculation” that can be printed and shown to you. However, as a check, we have included a rough calculation which shows approximately 11,500 cy of soil. See attached. Again, this is a very rough estimate that ignores some areas of random grading, but it serves to verify that the 13,600 cy determined from the computer model is realistic. 3. What happens to the waste water generated from washing the fire trucks? Response: If trucks are cleaned inside the station, the water will be collected in a trench that will drain to a grease interceptor unit prior to being released to the sanitary sewer system. If the trucks are washed outside, the

ROSEVILLE DESIGN GROUP, INC. • Established 1979 Architectural • Civil Engineering • Surveying • Planning • Structural Engineering September 3, 2014  Jon Green Home on the Range, Inc. 671 Newcastle Road, #7 Newcastle, CA 95603  Subject:  Newcastle Fire Station,  PLN14‐00044  (RDG project #13‐262)   Review Questions   

Dear Mr. Green,   We have received questions dated July 16, 2014 (forwarded to us from Placer County) and propose the following responses:    

1. Does the building design meet the requirements of the Design Corridor?  No plans have been available for public viewing. Response:  Yes.  

2. I would like to see the math explained for the estimated 13,600 cubic yards of fill dirt required.  My estimate is closer to 20,000 cubic yards.  How many dump truck trips will be required and what route will the tracks take? Response:  Using estimated 13,600 cy of fill, assuming 18 cy per truck load, about 

755 trips will be required.  This will take about 1 to 2 weeks to complete. 

   The earthwork volume was determined using AutoCAD Civil 3D 

computer program.  The program creates a 3D surface model of the site prior to grading and compares it to a 3D surface model of the site after grading is complete.  Unfortunately, other than the output, there is no “calculation” that can be printed and shown to you.  However, as a check, we have included a rough calculation which shows approximately 11,500 cy of soil.  See attached.  Again, this is a very rough estimate that ignores some areas of random grading, but it serves to verify that the 13,600 cy determined from the computer model is realistic. 

 3. What happens to the waste water generated from washing the fire trucks? 

Response:   If trucks are cleaned inside the station, the water will be collected in a trench that will drain to a grease interceptor unit prior to being released to the sanitary sewer system.  If the trucks are washed outside, the

water will surface drain to a storm drainage inlet located at the southeast corner of the parking area where a CDS unit will be installed.  The CDS system screens, separates and traps debris, sediment, oils and grease from the stormwater runoff.  Next, the water will flow to grassy swales for further water quality treatment. 

 4. What happens to the storm water runoff from the parking lot that may contain 

hazardous waste? Response:  Please see response to question #3 above.  

5. Will any of the tree loss be mitigated? Response:  To be determined by Placer County.  

6. Question 4 on page 8 has not been answered.  (not checked) Response:  The answer is yes.  

7. Will Old State Highway be closed for any period of time during the construction? Response:  We do not anticipate closing Old State Highway.  We do, however, 

expect the Contractor will need to close one lane from time to time to facilitate construction.  The Contractor will be required to provide a traffic control plan that is subject to approval by Placer County, and will provide all necessary traffic controls. 

 8. What is the plan for moving the sewer pipe on the property? 

Response:  The existing sewer pipe will be replaced and raised in the area of the proposed grading.  This is subject to approval by the South Placer Municipal Utility District. 

  Please let us know if you have any additional questions or comments.  Sincerely, Roseville Design Group, Inc.
