Home My WebLink AboutLINDEN TECH CENTER - Filed GC-GENERAL CORRESPONDENCE - 2004-08-16June 12, 1972 TO: The Honorable Mayor and City Council THRU: Mike DiTullio, Acting City Manager FROM: Charles Liquin, Director of Public Works RE: lion Pavel Annexation At the Council meeting on June 8, the annexation of the Linden Street Tech Center was discussed. At that time, a concern was voiced relative to flood plain. Enclosed herewith is a map of an old Flood Plain Study of this area made by the USGS. The area outlined in red appears to be fully outside of their concern at that time. I have checked with the Corps of Engineers in Omaha, who are doing the Present Flood Plain Study, and they are in the process of placing data on the computer but have no information on this area at this time. Based on the above, I would recommend that the City proceed with the annexation. Respectfully submitted, Charles Liquin Director of Publi Works CL/lms Enclosure calculation sheet from 1988 Drainage Report). Using a new weighted "c" value of .60 to calculate the storm watershed results in the following; 10-year storm - Q = 2.7 cfs 100-year storm Q = 5.4 cfs As you. can see these are insignificant amounts. .That and the fact that Catholic Community Services has a standing agreement with the ditch company to allow undetained offsite flow (see Agreement dated 6-20-•88 in City file for this subdivision) we feel it is unnecessary to detain any runoff. Thank you for your cooperation in this matter. If you or anyone in your office has any questions regarding this manner, please don't hesitate -to call.

Sundance Circle Fort Collins, Colorado Re: Linden Tech Center Dear Stephen: The utility drawings for the referenced subdivision were approved in 1972 showing a four -foot sidewalk along the west side of Linden Street between the back of the curb and the Coy ditch. We anticipate considerable pedestrian traffic along Linden Street in the future. Therefore, we expect the develper, through his engineer, to provide the City with. an acceptable design to accomplish what is shown on the utility drawings. Yours truly, - T±� � �_ urice E.

This does riot include the sidewalk on the west side of Linden Street or the extension and repair of the west wing wall at the ditch diversion structure. Since David Stringer Chief Engineering Construction Inspector ENGINEERING DIVISION January 9, 1981 Mr. Steve Robinson Stephen & Company 120 East Oak Ft. Collins, Colorado Re: Escrow Linden Tech Center Mr. Robinson: As you requested a visual inspection was made on the Linden Tech Center subdivision. The City cannot release a certificate of occupancy until the following have been carpleted: • Catch basin outlet pipe at Station 3+00 needs to be extended to the ditch flowline. • Catch basin inlet pipe at Station 5+58.75 needs to be marked, and the earthen d.em obstructing the corrugated metal pipe needs to be removed. • West side headwall at irrigation structure needs to be replaced and extended to match new curb and gutter. • Manholes and valve boxes need to be brought up to final grade. • The four -foot sidewalk on the west side of Linden Street needs to be installed. Sincerely, David Stringer Chief Construction Inspector ENGINEERING DIVISION January 15, 1.981 Mr. Steve Robinson Stephen & Company 120 East Oak Ft. Collins, Colorado Re: Certificate of Occupancy for Topanga Dear Mr. Robinson: per our conversations concerning the Certificate of Occupancy release for Tcpanga, the Engineering Services division will release this building without all of the required improvements per utility plans dated October 19, 1972. However the following items must be ccrq)leted before Certificate of Occupancy will be released on any other units within this subdivision. 1. Manholes and valve boxes brought up to finish grade. 1. Catch basin outlet pipes are to be serviceable per my letter of January 9, 1981. 3. Sidewalks and headwall structures either constructed or monies escrowed to insure completion, whichever you choose. Sincerely, David Stringer Chief Construction Inspector January 15, 1997 Glen Schlueter City of Fort Collins Stormwater Utility 235 Mathews Fort Collins, CO 80524 RE: Drainage Calculations Catholic Community Services CDS Project No, 96-8696 Dear Mr. Schlueter, This letter is in -regards to our conversation on January 13, 1997. At -that time we discussed the drainage concerns of the Catholic Community Services Addition to their existing building. This new structure is attached to the Northwest cornerofthe existing structure and covers approximately 88o sq ft. Along with the proposed addition there will be four parking stalls to serve the building. These will be located on the north side of the existing service drive (see the attached drawing for these locations). As I previously mentioned, we have changed the existing permeability of the total site by less than four percent. Using the Equation Detention Method this change would equate to a detention volume of .0032 ac-ft for a 100-year storm and 0017 ac- Lt for a 10-year storm (see attached detention calculation sheet). The developed runoff values for this site has been previously calculated to be 5.0 cubic feet per second for a 100-year storm and 2.5 cubic feet per second for a 10-year storm (see attached 165 2nd Street S.W. .
