October 4,1995 , .'Mr. Dennis Koblhaàs Y Scripps Bank Center . 411 South Escondido Boulevard - -, 'Escondido, CA92025 CARLSBAD GOLF PRACTICE FACILITY (PD 433) c - In response to your request, the City Engineer has agreed to defer some of the frontage improvements required of the Golf Practice Facility. This deferral extends only to the street widening along the property frontage with Haymar Drive west of the Haymar bridge and the street light proposed at station 124+50 on the improvement plans: The improvements east of the bridge and the streetlight just west of the bridge are still required to be installed at this time. The property owner will be required to enter into our standard Contract for Future Public Improvements for the deferred improvements prior to our releaseon the project., With regard to the Buena Vista Creek maintenance, the City does not concur with your, conclusion that the sediment and accumulated growth within the channel resulted in the flooding of the Golf Practice(Facility site The project site is- located entirely within the floodway for the Buena Vista Creek..It was clearly projected by this Department and your engineering consultants that the site would frequently be inundated during medium to heavy storm events'..It was for this reason that the .structures on the site were required to incorporate flood protection construction measures. The hydraulic analysis done for the Buena Vista Creek, and validated by the hydraulic studies done for the project, identified the bridge as the controlling factor for the upstream water elevation and, not the geometrics or condition of" the 'dównstréam channel. The channel condition was clearly evident prior to the construction of your clients project. If the condition of the channel was a major factor in the hydauIics of the site, then your clients consultant engineer 'should have made such identification and incorporated appropriate mitigation recommendations into the hydrology report With that said, the City does not object to your client removing any accumulated sediment, debris or vegetation from the channel immediately west of the Haymar bridge provided your client complies with the following requirements: . :. 1. Submit a sketch showing the location and extent of the area of the channel to be . cleared 1pclude a brief description of the types of vegetation to be removed and the construction method to be employed.

S Street Lighting: As we explained, it is our belief and that, of our lighting engineer, there is sufficient ambient light from the course lighting to illuminate Haymar Drive to City of Carlsbad standards. However, after our nieting and wherein you expressed your desire to have lighting in the bridge, we discussed this matter with SDG&E. We were informed SDG&E could readily install a Street light along Haymar Drive at the Buena Vista Creek crossing. This would illuminate the bridge and most of the street to the property line. SDG&E does not feel it is feasible to place a light standard further east than the bridge due to the contour of the hill on the one side, and the location of the creek on the other.-,We would however, stipulate through 'a Non-dispute Letter that we would mstall the second light standard at whatever time the road is improved :Buena.Vista.CreekAsyou: ie'callthecrëekthaIiné1 Wet Oftli€itë is overgrown with reeds, whereby a ñiassivebuildup ofsilt'Occutfed.
