Please note, in our review, we found a calculation error in the design documents which we go through in the certification letter. Everything still checks out and meets regulations per what has been constructed. Let me know if you have any questions.

This will need to be shown on the as - built drawings. Shelbeck to install riprap between September 15t" and 20th. David please plan to re -inspect the week of September 23rd. Now that we are all working off the same approved plans, Roudabush to include in final as -built drawings. The 6-inch storm drain that is supposed to collect the barn roof doesn't appear to be installed. The inlet in the manhole has plastic covering the hole (see photo). I forgot to confirm if the other building collector drains were installed (you'll need to confirm if these were installed). Your engineer will need to confirm if these were actually installed, and if not, if they were required for quantity/quality requirements. If so, they'll need to be installed or your engineer will need to show how those requirements will be met. This should be shown on the as -built drawings unless your engineer certifies they aren't needed. See Devin Keeler's response attached which includes: o Agreeing the 6" SD should have been labeled LID for underdrain. o Approving the deletion of LID for structural soil of the Fire Lane There are two trees planted over the 48-inch detention facility. These need to be relocated outside of the stormwater easement. See attached Landscape plan showing the relocation of these tree to take place in the Fall at the same time as replacements are installed. The Fall is the recommended time for planting and transplanting of trees. The 48-inch pipe looked fine except it has some gravel/mud that needs to be removed. Shelbeck to clean a second time between September 15t" and 20th. David please plan to re -inspect the week of September 23rd The mulch layer was not installed in the biofilter as required on the approved plans. Shelbeck to install mulch layer between September 15t" and 20th. David please plan to re -inspect the week of September 23rd The earth is eroding on the downstream side of the overflow weir. This needs to be corrected. Shelbeck to address erosion between September 15t" and 20th. David please plan to re -inspect the week of September 23ra Once all of these items are addressed, an engineer (typically the engineer of record) will need to write a letter certifying that the facilities have been installed in accordance with the plans. Dewberry was our Engineer of record, but Craig Kotarski of Timmons will certify all facilities are operating as designed. David James will be your contact from now on. Please route all correspondence through him as I will not have access to emails over the next two weeks. I have not reviewed the most recent as -built submittal, David will do this, but since there are changes needed, I am going to suggest he wait until corrections are made. David - I will confirm after all items have been addressed by the site contractor and officially request a re -inspection. Roudabush has submitted several as- builts already, should they provide final as -built drawings prior to your inspection or after? Which would be more efficient? I apologize for the timing of inspections and review of as-builts. We typically review as-builts with a site visit, and do not issue comments until both are completed so there isn't more than one set of comments. But in the effort to help you close this project before the end of the month, we went ahead and reviewed the as -built drawings without competing the field inspection, assuming everything was completed in the field correctly. We should have waited and next time I will make sure to do so. Sincere apologies for additional comments on the as -built drawings. Thanks, Frank Frank V.
