Durkin 4660 La Jolla Village Drive, Suite 1080 San Diego CA 92122 SUBJECT: PIP 00-04 - CARLSBAD RESEARCH CENTER LOT 24 Thank you for applying for Land Use Permits in the City of Carlsbad. The Planning Department has reviewed your Planned Industrial Permit, application no. PIP 00-04, as to its completeness for processing. The application is complete, as submitted. Although the initial processing of your application may have already begun, the technical acceptance date is acknowledged by the date of this communication. The City may, in the course of processing the application, request that you clarify, amplify, correct, or otherwise, supplement the basic information required for the application. In addition, you should also be aware that various design issues exist. These issues, listed below, must be addressed before this application can be approved administratively. Please contact your staff planner, Michael Grim, at (760) 602-4623, if you have any questions or wish to set up a meeting to discuss the application. Sincerely, i MICHAEL JXOLZ~~ILLER Planning Director MJH:MG:mg C: Chris DeCerbo Jeremy Riddle File Copy Data Entry Planning Aide Steve Hall, Chapo and Hall Architects 1635 Faraday Avenue Carlsbad, CA 92008-7314 (760) 602-4600 FAX (760) 602-8559 www.ci.carlsbad.ca.us 49 ,- ISSUES OF CONCERN NO. PIP 00-04 - CARLSBAD RESEARCH CENTER LOT 24 Planning: 1. The standard parking space measures 8.5 feet by 20 feet. Up to 2.5 feet of that parking space may overhang, however this overhang shall not interfere with pedestrian circulation. The proposed overhang in front of the building should be revised to include wheel stops or bollards that prevent the automobile from overhanging into the required width of the circulation for physically-challenged individuals. In addition, landscaping strips and islands within the parking area are measured from the inside edge of curbing rather the outer extent of curbing, as shown on the site plan. 2. The City’s Landscape Manual requires an average of one parking lot trees for every four parking spaces. Please provide on the landscape plan an indication that the proposed development meets this requirement. 3. The proposed deferment of indoor employee eating area to the tenant improvement is unacceptable since no discretionary action is required for the tenant improvement and the building could be occupied by more than one tenant. Please either specify the location of the indoor employee eating area on the floor plans or accept a condition requiring that the first tenant improvement building permit must include the entire indoor employee eating area(s). 4. Based upon updated information from the County of San Diego, lot 24 of Carlsbad Research Center is located within the over 75 dBA CNEL noise contour for the McClellan-Palomar airport. According to the existing Comprehensive Land Use Plan for McClellan-Palomar airport (CLUP), only agriculture (except residences and livestock), extractive industry, fishing, utilities, public rights-of-way and golf courses are allowed within this noise contour. Therefore, an inconsistency between the industrial subdivision (as zoned) and the CLUP exists. Staff from the City, County, SANDAG and the McClellan-Palomar airport are investigating this inconsistency and will apprise you of the outcome once derived. Engineering: 1. It is our understanding that this project will require the installation of on-site fire hydrants. Please meet with the Fire Marshal to establish a preliminary layout of these hydrants. All fire hydrants are to be served by public water mains. On the site plans, depict the limits of a proposed public waterline system required to serve the project. Indicate a preliminary horizontal alignment per Carlsbad Municipal Water District Standards, latest edition. 2. On the site plan, complete the date of preparation of the plans. 3. On the site plan, add a typical street section for Dryden Place. 4. On the site plan, depict all easements listed in the title report (see item 4, 6, 8, 10 and 11 of the preliminary title report). Add record data for all reference easements on the property. 1 . 5. On the site plan, identify horizontal distances between the proposed driveway centerlines and adjacent driveways (intersection spacing). 6. Provide a recent Soils Report identifying specific recommendations for this project. The Report should identify the limits of any anticipated onsite remedial earthwork. 7. Provide a hydrology report that addresses how water is intercepted, conveyed and discharged across the site. Ensure that NPDES requirements are met (see related concerns below). The updated National Pollutant Discharge Elimination System (NPDES) permit is nearing approval, and would involve significant changes to this project and other projects processed throughout the San Diego region. It is our understanding that these changes will not include a grandfather clause for projects. This means that this projects and all other projects will be impacted pursuant to the approved NPDES requirements, no matter what stage the project is in. We encourage you to review the draft permit requirements (www.swrcb.ca.qov/-rwqcbg) so that you understand the nature of our comments when they are made on projects. In order to facilitate compliance of this project, the following are some criteria that should be incorporated into the design of the project: a) Post development storm run-off flows and velocities should not exceed pre- development storm run-off flows and velocities during a 10-year, 6-hour storm event. This shall be proved via engineering calculations in a project hydrology/hydraulic report. Revise the site plan to incorporate all measures required to detain any increases in flows. b) Include additional BMP (Best Management Practices) measures to capture pollutants from the parking lot. In general, grass-lined swales should be utilized to filter storm water before entering inlets. These tend to be the most efficient, long-term pollutant filter. c) Offsite and downstream'siltation would not be permitted at any time during the project (long term or near term). d) For projects disturbing more than one (1) acre of soil, submit a Storm Water Pollution Prevention Plan (SWPPP) that addresses both construction and post- construction phases of the project. The SWPPP will be required before the permit issuance. 8. If a westerly portion of the proposed parking lot will drain into the existing drainage (swale) system, a portion o the swale may have to be demolished and rebuilt as a grass- lined swale to filter pollutants from the proposed development. 9. Add a legend to the site plans to differentiate between existing and proposed items. 10. Revise the site plan to include the application number "PIP 00-04" in the upper right- hand corner. 11. Include all proposed surface elevations (top-of-curb, finished surface, flow-lines, drainage arrows, etc.) to demonstrate how storm water will be conveyed from the site. c I . 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. Depict existing topography at least 50 feet from the north property line. Depict the location of all existing driveways adjacent to the site and across the street. Include the driveway slopes as they approach Dryden Place. -. Include minimum 10-foot vertical curves on all driveway approaches to soften grade breaks just beyond the property line. Provide 5-fOOt offsets at parking lot corners to allow for vehicles to back up. Depict the turning radius for trucks entering and exiting the site plan from Dryden Place to verify that vehicular movements do not conflict with opposing traffic. Consider widening the driveway to 30 feet to address rear tire tracks. The proposed waterline system must be looped and both connections should be located in the proposed driveway entrances. The waterline should be located within the paved drive aisles. If improvements for lot 23 and lot 24 (PIP 00-04 and PIP 00-05) are constructed simultaneously, then one connection to Dryden Place could be required for each lot at the discretion of the District Engineer (versus two). In this scenario, the southwesterly driveway on lot 23 would have a street connection and the easterly lot 24 would also contain a street connection. If the projects were constructed independently, then each of the lots would stand alone as an individual looped system. Ensure that proposed waterline includes a stub for future connection to the west to lot 23. Depict a proposed 20-foot waterline easement to the Carlsbad Municipal Water District that encompasses the proposed waterline system. The waterline should be centered within the easement. Clarify the location of the irrigation service using the legend symbols and identify the approximate demand (in GPM) at the point of the connection. On the site plan and landscape plan, depict the line-of-sight and both project entrances using Caltrans Standards. Verify no conflicts exist (see entry monument). Add earthwork totals, EDUs (sewer), GPM (potable), and GPM (recycled) to the site plan. Include any new water services (and/or irrigation services) to the rear portion of the site to allow water circulation in the new looped water system for water quality purposes. A redlined check print is enclosed for the applicant’s use in making the requested revisions. This check print must be returned with the plan revisions to facilitate continued staff review.
