Why are the street intersections/connections with Castlerock Parkway not shown in the profiles? (Stone Shadow Trail, Rock Bend Drive, Rolling Stone Drive) Response: The plans have been changed to include these intersections. 2. How will you insure that the drainage will not undercut the roadbed on Stone Shadow Trail, Rock Bend Drive, Rolling Stone Drive, and south end of Rocky Creek Trail? Response: Each of the locations cited above are places where water runs onto the street from vacant land adjacent to it. These streets will eventually be extended when future phases of the subdivision are built. While no one can guarantee that problems will not occur, undercutting of the new streets is not likely because there is no place for water to flow under the street that would cause erosion problems. The ends of the street will be backfilled with spoils from the excavation and sloped gently upward to existing ground to facilitate drainage into the gutters. If unforeseen problems occur prior to the extension of the streets, remedial measures will be taken at that time to insure the integrity of the roadway and subgrade. 3. Indicate limits of structural backfill on Storm Pipe 2P3. Response: The plans have been changed accordingly. 4. Please insure that where there is a change in pipe diameter, the soffit of smaller upstream pipe shall at least match the soffit of the larger pipe. Response: We did not see a location where the soffits did not match. If there is a specific location where this occurs,please advise us do it can be corrected. 5. What is happening at the outlet of Pipe 5P4? What is the grading from roadway to drainage channel 2? Response: The plans have been changed to show how the contours accommodate the small flow coming from the gutter. The intent is to provide a path for water from the gutter to flow down the channel bank into the larger ditch without causing significant erosion. The large channel and the small channel will both be removed when the street is extended with Phase 2 of the subdivision. They will be replaced by inlets and storm drain pipes. 6. Provide protection from erosion on drainage channel over sanitary sewer line where cover is proposed at 2' (S-1). Response: The plans have been changed accordingly 7. Provide cross-section of drainage channels. Do you have enough rip-rap at outfall to Channel No. 1 to reduce the velocity to acceptable range for seeded grass surface treatment? Response: A cross-section of the channel has been added to the page. Additional rip-rap has been added as well. The temporary channel will be privately maintained until the street is extended with future phases of the subdivision. If excessive erosion begins to occur, measures will be taken by the owner to mitigate the problem. 8. The storm collection system will be considered private south of where street pavement ends. Response: That is our understanding as well. 9. Please confirm that the TXU gas line is not high pressure. If it is high pressure show approximate depth. (W-1) Response: The line is not high pressure. It is the same 6"poly line that serves the C'astlegate Suhdivsion. Castlerock Subdivision, Phase 1A— Final Plat Response to Staff Review Comments No. 1 (dated 9/12/2006) Planning Noted. ,_/2. Vicinity map has been corrected. /3. All utility easements have been labeled on the plat. /4. All "Greenbelt" or `Buffer Area" labels have been changed to read "Common Area" so that Note 10 makes sense. Engineering 1. The CLOMR floodplain has been added to this map, and it is almost identical to the FEMA FIRM line in this area. 2. The Conservation Easement was developed as a part of the Corps of Engineers (COE) permitting process for the Crowley Tract and SH 40. All of the state and federal agencies were involved in this process and the COE permit was approved with regional detention at the downstream portion of the Crowley Tract, with the runoff from the developed portions of the Crowley Tract and Castlegate flowing through the Conservation Easement to the regional detention pond. The issue of discharging into the Conservation Easement has already been resolved with the COE permit, the granting of the Conservation Easement, and the dedication of the property to the City of College Station by Tim Crowley, which specifically gives the upstream landowners the right to allow their storm water to flow across the Conservation Easement. 3. Permits will be submitted. 4. A blanket easement application will be submitted for the entire tract. 5. Noted. ,/Electrical 1. The application for the blanket easement will be provided. 2. Noted. 3. Easements have been added per the master plan file for electrical sent by Brent Read. Some of the requested easements will be added in future phases, but will be covered under the blanket easement for this phase. Are 1. There are 30 lots in this phase. Sanitation 1. Rocky Creek Trail can serve as a turnaround, making a temporary turnaround Aft unnecessary.
