First and foremost, there will be no further review of the civil portion of the Major Plat due to the non-response to repeated requests for detailed long term ground water monitoring. In addition, 2 test pits are not adequate for a site this size. Infiltration must be shown as infeasible in order for the project to claim that it is infeasible and not use it. Provide detailed accounts of testing and tabulated results.

The following City comment is to address the Engineers response to a previous City comment: PREVIOUS CITY COMMENT (12/31/2020): The State highway basin does not meet the criteria for full dispersion. The total impervious area exceeds the 10 percent threshold. The overall site is 13.319 acres (2.579 acre onsite plus 10.74-acre native easement). The total impervious is 1.62 acres (.59 acres within the roadway and tracts as measure of drawing plus .844 acres for roof plus .184 acres for driveways). The impervious percentage equals 12.2%. Also, the eastern most flow path slope exceeds 15% based on existing contours. Please revise stormwater report to address this issue. RESPONSE FROM CLIENT'S ENGINEER (12/30/2021): The storm drainage report will reduce the amount of roof area to 3,600 square feet per lot for a total of 0.66 acres, 0.184 acres driveway (average of 1,000 sf per lot) and 0.474 acres of roadway. The basin will have a total of 1.318 acres which meets the ten (10) percent threshold. CITY COMMENT ON RESPONSE: It is unclear to reviewers how the roadway will be reduced from 0.59 acres to 0.474. Although a Storm Report and Plans were submitted with this response, the documents either had not been updated since October 2020, or it was not made clear which portions of the documents had been updated. They are both still showing a date of October 2020 which is before the 4th correction notice; from which these comments came, was issued. The client will need to clearly demonstrate on the Civil Plans that the roadway impervious has been reduced and that the total basin meets the 10% requirement. Also, eastern most flow path slope comment not addressed. Revise stormwater report to address these issues.

The following City comment is to address the Engineers response to a previous City comment: PREVIOUS CITY COMMENT (12/31/2020): A portion of lot 6 and 7 and all of lot 8, tract C and the proposed 5’ walkway is graded towards the north east. The storm report shows a portion of this as a bypass basin that is included in the Shaw Road basin. The bypass basin does not match the grading. Show how the increase in runoff for the northeast corner of the plat will be mitigated? Please revise stormwater report and provide a qualitative description/analysis to address this issue. RESPONSE FROM CLIENT'S ENGINEER (12/30/2021): The proposed drainage for these lots is being directed to the dispersion area to the north. The post developed basin shows a small bypass area which has been accounted for in the drainage model. CITY COMMENT ON RESPONSE: It will need to be clearly demonstrated on the civil plans how the water is being conveyed from the lots to the dispersion system. Also clearly demonstrated and described will be the bypass scheme for this basin. The current submittal does not provide enough detail to completely review the drainage in relation to the basins.

The following City comment is to address the engineers response to a previous City comment: PREVIOUS CITY COMMENT (12/31/2020): The access tract shown the storm pond is 20’; City Engineering standards requires a 40’ easement. Previous response noted that an AMR will be submitted to reduce the width at the time of Civil Permit. If the AMR is not approved the buildable area of lot 16 will be impacted. Either the easement shall be widened as part of the preliminary Plat or the AMR shall be submitted and approved prior to Preliminary Plat approval; please address this upon resubmittal. RESPONSE FROM CLIENT'S ENGINEER (12/31/2021): Attached is the AMR requesting the reduction of the easement width. CITY COMMENT ON RESPONSE: After further review and discussion the City has determined that an easement is not required because it is in a dedicated tract. City Standard 206(2) discusses the requirements: Publicly maintained water quality and R/D facilities shall be located in tracts dedicated to the City. The size of the tract shall be based on the size of the stormwater facility. At a minimum, the tract shall include the entire facility, site access area, and at least 5-feet of clearance around the facility. All publicly owned and maintained stormwater tracts/parcels shall be fenced at the property line. Fencing shall meet the minimum requirements of City Standard Detail 06.01.08 – Type 1, Chain Link Fence. Section 205.2 of the City Standards requires the access road in a tract to be a minimum of 15 feet wide. Employing the minimum 5-foot buffer to each side of the access road would result in a 25-foot access road within Tract B with the pipe centered in the access road.

The following City comment is to address the engineers response to a previous City comment: PREVIOUS CITY COMMENT (12/31/2020): The storm pond does not meet City Stormwater Standards; revise the design upon resubmittal addressing the following issues. a. The Storm pond shall setback 20’ from any property line. b. The storm pond is located within a steep slope buffer. Per the DOE stormwater manual, the facility shall not be located above a slope that exceeds 15%. c. The Drainage Report models to have a bottom that is 79.1’ by 79.1’. The bottom of the pond shown on the preliminary plat is approximately half that size. d. The storm pond will be City owned infrastructure. The city does not accept its current location above a steep slope that leads to a wetland. This configuration will likely case additional maintenance and has a potential for failure over time. The pond shall be relocated to a more suitable location outside of any critical areas or buffers. RESPONSE FROM CLIENT'S ENGINEER (12/30/2021): a. Please provide specific location where the pond does not meet the 20-feet b. The geotechnic engineer addressed this in their previous memo c. The pond bottom is 60 x 120 feet which is approximately the same area d. The previous Geotechnical Engineering memo addressed the location of the proposed pond in relation to the steep slope CITY COMMENT ON RESPONSE: a. Ensure that the pond is a minimum of 20-feet from any structure, property line, or vegetative buffer and 50-feet from steep slopes per Volume V, Chapter 10.3 of the SWMMWW. b. Cannot locate information in “previous memo”. Specify document version and page number where this is addressed. Reviewers read the 6/24/2019 updated Geotech report, the 10/23/2020 addendum to the Geotechnical Report and the updated October 2020 Storm Report and cannot find any mention of how the design will conform to the Ecology Manual’s provisions for ponds near steep slopes and, in fact, these documents still refer sporadically to a stormwater vault. c. Model the pond as it is proposed to be constructed. d. See Comment on Response 8.b.

The following City comment is to address the engineers response to a previous City comment: PREVIOUS CITY COMMENT (12/31/2020): The storm design does not adequately show that the project meets MR #8 of the 2014 DOE Stormwater Manual. Please revise stormwater report to address this issue. a. The Hydroperiod needs to match the guidance included in Appendix I-D. Provide a revised analysis/design that shows the project meets MR #8. The hydraulic analysis shall also be evaluated by the project wetland Biologist to verify that there is no new loss. b. The three consecutive wetlands have been modeled as one wetland. The conveyance between wetland A and B appears undersized. Provide an analysis that show the three are hydraulically connected to function as one. RESPONSE FROM CLIENT'S ENGINEER (12/30/2021): a. The wetland biologist reviewed the analysis and the calculations to verify there is no new loss b. Please provide direction on what the city would consider the critical path with regards to the wetland and drainage. The intent was to preserve the wetland removing and replacing culverts will impact the wetland and require mitigation. CITY COMMENT ON RESPONSE: a. The direction from the City was to revise the stormwater report and analysis to demonstrate to reviewers that the project meets Minimum Requirement #8. b. The critical path is conforming with applicable City and State design standards. Provide an analysis that demonstrates proper culvert capacity and that the wetlands are hydraulically connected.

The following City comment is to address the engineers response to a previous City comment: PREVIOUS CITY COMMENT (12/31/2020): The storm report does not provide enough information to determine how the wetlands and storm system will function. Once the storm pond is constructed the wetland will function as part of the onsite storm system. a. The existing culvert between Wetland A&B appears undersize for the volume of water that is being contributed to wetland A from the adjacent neighborhood. b. Provide a complete hydraulic analysis of the wetlands, ex culvert/control structure, inlet to the wetlands and outlet. c. As part of the analysis show how the downstream storm system will be affected by any changes to the existing wetlands hydraulics. RESPONSE FROM CLIENT'S ENGINEER (12/30/2021): a. The wetland has functioned for several years in the existing condition. The intent of the storm design was to maintain the wetland hydrology while meeting the flow control requirements. Adjusting or changing the wetland culverts will impact the wetland function. Is the city suggestion we replace the 3 existing culverts so the drainage can flowthrough the wetlands? A note can be placed on the plans indicating the culvert replacement. b. An analysis was provided in the preliminary storm report. c. It was not our intention to change the downstream hydraulics. CITY COMMENT ON RESPONSE: a. The existing condition is being changed by the development. Sine it is the applicant that wants to discharge to the wetlands, thereby altering the historical function, it shall be the applicant that demonstrates compliance with local regulations. b. The analysis shall be enhanced prior to civil submittal to include details about the proposed control structure, inlet and outlet to and from wetlands, and capacity of the system on-site and downstream. c. All new development impacts the downstream areas and hydraulics.

ADDITIONAL COMMENTS: -Geotech Report and other documentation still refer to a detention vault and older lot configurations. Ensure that all documents including reports, plans and model outputs on subsequent submittals represent the most current design. Any reference to design elements that are not part of the project will result in the review being halted. This will help lower the amount of subsequent reviews and re-submittals. -The modeling and the design discount groundwater. Wet weather modeling to determine the peak groundwater level to inform pond and general site design is required. See #3 under Engineering Conditions from DRT Letter #4. Display results of wet weather monitoring in detail including groundwater levels on particular wet weather dates showing a peak over a specific period of time. -The Stormwater Report claims that the State Highway Basin is dispersed over a full ¼ mile, but the easement is only for 100 feet. If the full quarter mile is to be used for stormwater dispersion, then the size of the easement (unbuildable area) must be commensurate. In addition: • Dispersion area is located in right of way. Unless it was previously discussed by past reviewers, CBs #14. #16, and #18 should be relocated to the future curbline within the newly dedicated ROW on 19th Ave SE and the dispersion infrastructure moved outside of the ROW not only for 19th Ave SE, but for the future dedication of 21st St E. • The area proposed for the dispersion paths needs to be a part of the project. Either an easement or a dedicated tract (City Standard 206(2)). • According to documents submitted by the applicant there are wetlands and slopes that may exceed regulations for dispersion on parcel number 0420353009. There are also wetlands on the west side of 21st St E. Dispersion is not allowed in critical area buffers or on slopes exceeding 20%. Provide rationale or revise, clearly indicating all wetlands and buffers.
