As requested, we have completed our review of the site plan provided for the Quarry Creek Planning Area 3 (R- 3). Compared to the approved traffic study for the Quarry Creek project, the residential unit count has increased by 20 units as discussed and approved in several previous memos and conformance reviews with the City of Carlsbad. Thi s minor increase from 188 units to 205 units has previously been reviewed and approved and will not be discussed here. However, there is also a minor reconfiguration of access. Previous plans showed "Public Street D" connecting all the way through R-4 to a cul-de-sac at the terminus of "Public Street A" as shown in Attachment A. The cu rrent configuration would have "Public Street D" terminating at a cul-de-sac at "Private Driveway A" within R-4. This would serve as the terminus of "Public Street D" with traffic wishing to travel to "Public Street A" having to traverse private drives. The current proposal is shown in Attachment B. We have evaluated the effect of this redistribution of traffic and have determined that the planned configuration will function adequately without significant effects on Street A. This analysis is discussed below. Trip Generation The anticipated trip generation from R-4 is shown in the Table 1. Redistribution of Traffic As discussed above, the minor alteration in access and connection of "Public Street D" will cause a redistribution of traffic due to the removal of a direct connection to "Public Street A". However, this will primarily effect traffic from R-5 which already planned primary access fro m "Public Street A". Therefore, the redistribution is anticipated to be minor with a small increase in traffic resulting at the intersection of "Street B" and "Street A". Thi s redi stribution is expected to result in the volumes shown in Attachment C with peak hour volumes at the intersections at "Public Street B" being very similar to previous studies. Conclusion: Based on the volumes in this analysis, it is not anticipated that the reconfigured access will have any impacts or cause any changes to the planned roadway network for the Quarry Creek Master Plan area.
