I told Alex that ultimately this is a question for you and Dick and that if you are comfortable with them grading the trail itself to smooth it out or whatever then that’s your decision but that they should not cause any permanent vegetation loss in these excluded areas, at least not until after all other veg removal has occurred so that we can be sure that they won’t exceed the acreage that has been allocated. From a bio perspective ideally they’d follow the plans and not remove anything at all in these “protect in place” areas but if really necessary it should come at the end of all other removal work and only after acreage has been pre-confirmed. * As of the end of last week the project has permanently removed approximately 0.0295 acre of CSS, or approximately 16% of the approved limit of all CSS. Finally, Alex had a couple questions for me that I told her I’d pass on to you because I think they fall more within your area. 1. Should the crew be removing vegetation or casting it aside into piles on the side of the trail? This is not specified in the MMRP, but it does say in the MMRP under the Aesthetics measure that vegetation piles should be, “staged and screened from public view in a designated construction staging area. Staging areas shall be approved and subject to periodic field inspections by the City of Diamond Bar Parks and Recreation Department, or responsible designee(s).” This indicates to me that they shouldn’t be just casting vegetation to the side of the trail as they go but I wanted to confirm an approach with you. 2. Does the project have an oak tree permit? This was pointed out in the original bio report that removal or pruning of oaks and walnuts (both of which are on-site and may require pruning) may require a permit under Chapter 22.38 of the Diamond Bar Municipal Code; however, I’m uncertain if the City itself would need a permit for its own project or if any pruning would simply be conducted under the City’s oversight pursuant to the municipal code. Again I won’t be able to make it to the meeting this morning. However, I am happy to talk over the phone later today if you want to catch up on any of these items or make sure we’re in agreement with everything. I will also be in touch with Alex later today as well to follow-up on things. Thanks!
