The widening on Palomar Airport Road consists of an additional eastbound lane beginning at El Camino Real and ending at Melrose Street as well as an additional left tum lane onto the westbound lanes of El Fuerte Avenue. El Camino Real widening includes an additional lane between Palomar Airport Road and Orion Street for deceleration purposes. The Orion Street (the access road to the Carlsbad Water District and Coast Waste Management) widening consists of an interim 48' Right of Way and a future Right of Way of 72'. Finally, the widening of Faraday Drive will accommodate an additional left tum lane onto southbound El Camino Real. The purpose of this study is to address the impacts of the proposed widening of Palomar Airport Road, El Camino Real, Orion Street and Faraday Drive on the existing drainage flow. This analysis will incorporate the drainage report dated October 18, 1991.

The runoff coefficient "C" is a coefficient expressed as the percentage of rainfall which will become surface runoff. Some of the rainfall will not become mnoff and will infiltrate into the soil or evaporate. Different values for this coefficient are listed on page II-2, Rational Method Runoff Coefficients, from the Master Drainage Study for the City of Carlsbad. Average rainfall intensity, "I", in inches/hour is determined based on a time of concentration (Tc) of the contributing storm. The time of concentration is the time required for storm runoff to flow from the most remote node of a drainage basin to the outlet node (lowest node) under consideration. In natural and urban watersheds, the "Tc" is determined from County of San Diego Appendices X-A, X-B, and X-C respectively. The 6-hour and 24-hour precipitation needed for use with the above charts were determined from the San Diego County 100-year isopiuvial charts as shown on pages II-3 and II-4. "A" is the area of the drainage basin, and is determined based on the path the rainfall will take when running downhill. The delineation between basins marks where the water will flow in varying directions. All the rain falling within a basin will typically flow to the lowest point in the basin. These drainage basins are shown on the hydrology maps. Manning's equation has been used to calculate flow characteristics for certain improvements. Manning's "n" of 0.013 was used for reinforced concrete pipe and 0.015 for improved channels. P:\...\75104 \DOCS\HYDRO \104HYROI.

This report should perform a hydraulic grade line analysis for all proposed storm drains, and a confirmation of adequacy for existing storm drain to remain. 2. Improvements to existing storm drain as shown on Exhibit "B", proposed Hydrology, or as recommended in this report, shall be done with the fmal grading plans or improvement plans, whichever is applicable. 3. Any storm runoff during construction shall be in conformance with the NPDES permit for the City of Carlsbad. P:\...\75l n4\DOCS\HYDRO\l 04HYROI.
