The most recent 30-yr data set from 1992-2022 with 50% prob of >28 degrees gives 243 days, with a date range of 3/19 to 11/16, which we will utilize for the entire monitoring period. We will provide a statement about defaulting to the WETS table to establish growing season, within the MY report and include the WETS table within the appendix of the MY report. Let us know if this amendment to the MY will work.

Here are some thoughts on growing season dates, but the take-home message is that the dates should be established in the beginning and stay consistent throughout monitoring. If the NRCS WETS tables state that March 1 - Nov 13 is the growing season, then we are fine if you use those dates and stick with them. There's no need to take soil temperatures and measure vegetative indicators. If the WETS tables list a different set of dates, you should use those dates. If you would like to use a modified growing season that is not listed in the WETS tables, you will need to measure the soil temperature using a continuous monitoring device, and document vegetative indicators such as bud burst and leaf drop. Ideally, this data would be collected prior to submitting the final mitigation plan so you have accurate dates, similar to collecting pre -data for hydroperiods. If you decide to use a modified growing season, once you establish the dates (assuming it's a normal year), you will need to stick with those dates throughout the life of the project for consistency. A lot of inconsistencies can occur when documenting bud burst and leaf senescence, such as which species are selected, the location of the vegetation, shading, etc., so that's why it's best to only measure the vegetative indicators once and stick with those dates. Let me know if you would like to discuss.

Actions and responses will be incorporated into the Year-1 field monitoring and subsequent report where applicable. Thanks, Kevin Kim Isenhour, USACE: 1. I concur with DWR's comment #6. When the Corps issues the Intent to Approve letter, it is with the understanding that we are approving the Draft Mitigation Plan, contingent upon the IRT comments being addressed in the Final Mitigation Plan. If additional changes are made to the Final Plan, those changes/additions should be added to the errata sheet Response to IRT comments and submitted with the Final Plan. Re: Apologies for the misunderstanding. This has been noted. Additionally, Dactylis glomerata will not be proposed for seeding in future projects. 2. Section 42: Were groundwater gauges installed to collect pre -construction data? If so, it's helpful if you include the pre -construction gauge data in the MYl report to show functional uplift. Re: Pre -construction gauges were not installed. In future monitoring, please capture the wetland reestablishment areas on UT-3 and UT-4 with random plots. Re: The wetland reestablishment areas along UT3 and 4 will be captured with random plots during MY1 monitoring and beyond. 4. I concur with EPA's comment #1. Re: See response to EPA comment 41. 5. Page 7: What is the growing season start date? You should state a growing season start date and use that same date throughout monitoring for consistency. Re: The growing season is listed in section 3.0 as March 1 to November 13, with the March 1 start date to be confirmed by soil temperature and documented bud burst. If these parameters are not met on March 1, the growing season start date is subject to change depending on when the parameters are met. This is the methodology outlined in the approved mitigation plan. Please advise if the IRT would like to see different growing season start/end dates or methodology for MY 1. Erin Davis, NCDWR: DWR was glad to see the change from culvert to bridge stream crossings. Re: Noted. 2. Based on the monitoring summary table, please clarify whether the growing season start date is proposed to vary from year to year during monitoring. Re: The growing season will be March 1 to November 13, with the March 1 start date to be confirmed by soil temperature data and documented bud burst. If these parameters are not met on March 1, the growing season start date is subject to change depending on when the parameters are met. This is the methodology outlined in the approved mitigation plan. Please advise if the IRT would like to see different growing season start/end dates or methodology for MY 1. 3. DWR understands that stem species identification at as -built is a challenge and may be corrected in the MYl survey. However, we would recommend keeping an eye on species diversity, particularly in plots currently showing only 3 to 4 species or a significant number of Sycamore. Re: Species diversity will be watched closely during year 1 monitoring. 4. What was the stream condition along UT7 that initially warranted the proposed structure installation? DWR understands that this is an enhancement reach, but what is the risk of stream instability and/or potential sediment source to downstream if the current stream condition is not addressed through an alternative treatment or structure? Re: The stream is incised, and the log cross vane was initially proposed to reduce further incision. Although property constraints prevented installation of this structure, another cross vane was installed further downstream where property boundaries allowed, and a large marsh treatment area was installed above the stream origin to catch sediment. Further the stream bank has become densely vegetated with rooted black willows to aid in stability. If the stream bank does become unstable and a sediment source, remediate measures will be taken. 5. As noted in the report, some of the permanent veg plots shifted compared to locations in the approved final mitigation plan monitoring plan figure. DWR questions whether the new locations provide representative coverage to demonstrate performance standard success for all proposed credit areas. DWR requires either veg plot 19 or 20 be relocated to nearby wetland reestablishment areas. Re: One plot, either plot 19 or 20, will be moved into a nearby wetland reestablishment area prior to MY 1 monitoring. 6. For future projects, please don't propose seeding orchardgrass (Dactylis glomerata) within the project easement. Orchardgrass is a perennial non-native species. It wasn't in the draft mitigation plan, and I didn't catch its addition to the final mitigation plan. Re: Dactylis glomerata will not be proposed for seeding in future projects. Todd Bowers, USEPA: 1. Table 6a/Page 33 and 124: Recommend adding the wetland indicator status here and updating the table to show deviations from proposed planting plan in final mitigation plan. Re: Red -line changes from the design planting plan to as -built are on sheet AB-04W of the record drawings (Appendix F). Wetland indicator status will be added to each species in the planting list in the MYl document. 2. Modifications made during construction and red line deviations in site plans noted with no issues. The explanation given in subsequent documents as to why bridge crossings were changed from culverted crossings is sufficient but I am curious if there was a significant increase or change in the cost of the project. Bridge photos were excellent but an oblique angle of the crossing would be valuable. Re: Noted. 3. While overall, vegetation stem counts are performing as expected, several plots have dominant species (>50%) and/or less than 4 species. Recommend keeping a close eye on the areas with these plots (fixed plots 3, 7, 9, 11 and random plots 1, 2, 7, and 9). Re: The bare -roots were thoroughly mixed up before planting occurred, however, some overlap with same species can occur with planting crews. Species diversity will be watched closely during year 1 monitoring. 4. Table 7/Page 35: I'm not convinced that success criteria was met for all the plots for the reasons mentioned above if diversity and dominant species are considered. Re: This will be re-evaluated during MY 1. 5. Overall, I am very satisfied with the report and the work that CMS has completed at the site. Having not been able to visit this location, I really appreciated the detailed ground -level wetland, vegetation and stream feature photos to illustrate the grading, planting and features implemented. I recommend the appropriate credit release (Milestone 2) for warm stream and riparian wetland mitigation units for this monitoring milestone. I have no other substantial comments not requesting a site visit at this time. Re: Noted, thank you.
