Ms. Katie Larsen <br />10/03/2025 <br />Page 3 <br />Erickson Property Development - Engineering Review <br />WSB (10/3/2025) Marked up grading plan provided – Coordinate grading and <br />structure work on adjacent properties with existing residents and Lennar. <br />Update grading plan following finalization of elevations with Lennar/Carlson. <br /> <br />c. Utilize current grading as-builts/plans for Watermark <br />Landform Response (8/11/25) – Understood. <br />WSB (9/3/2025) Show existing EOFs and proposed contours should maintain <br />minimum 2% slope <br />Landform (8/11/2025) Additional EOFs have been added to plans. Additional <br />slope arrows have also been added to better illustrate proper drainage of <br />site. See sheet C3.1 <br />WSB (9/26/2025) A revised eastern grading exhibit will be distributed for <br />discussion early next week. This exhibit will need to be discussed internally <br />and with both Hampton/Landform and Watermark/Carlson to finalize <br />Landform (9/30/2025) Acknowledged <br />WSB (10/3/2025) Marked up grading plan provided – Coordinate grading and <br />structure work on adjacent properties with existing residents and Lennar. <br />Update grading plan following finalization of elevations with Lennar/Carlson. <br /> <br />5. Drainage from one lot to another requires drainage and utility easement <br />Landform Response (8/11/25) – Updated. See Plans. <br />WSB (9/3/2025) Complete <br /> <br />6. Propose future 'ghost' grading including roadway for remaining area between <br />Erickson Property and Watermark 6th to justify temporary retaining walls and how <br />they will be removed in the future <br />Landform (8/11/2025) Retaining walls removed <br />WSB (9/3/2025) Propose future 'ghost' grading including roadway for remaining area <br />between Hampton Property and Watermark 6th to show how future elevations will <br />work and how they can be achieved transitioning from proposed to future lots <br />Landform (8/11/2025) Future design on the Kominski Luther property will be <br />completed at the time of site development by others. A future ghost plat with a <br />possible future road horizontal alignment and future vertical profile are provided on <br />sheets c2.1 and c6.1 that shows a possible road connection thru subject property. <br />Providing a ghost grading is outside of Erickson property project limits and scope. <br />WSB (9/26/2025) A plan must be created that shows how the grades now will <br />transition to the future road extension grades while minimizing the impact to Lot 1 <br />Block 1 and Lot 7 Block 2 similar to Watermark 6th. <br /> <br />Future grading should only take place in the drainage and utility easements <br /> <br />This plan will be conveyed with the sale of the lot so the homeowners are aware of <br />potential future impacts <br />Landform (9/30/2025) See the future grading exhibit included in this resubmittal for <br />the future road extension grading. <br />WSB (10/3/2025) Update grading exhibit and identify future ‘shaded’ areas to be <br />impacted. Magenta elevations and contours are current, red elevations are future. <br />Update grading plan. <br /> <br />a. This may include temporary retaining walls or easements on the proposed <br />lots <br />Landform (8/11/2025) Retaining walls have been removed from the design, <br />no other retaining walls are proposed in the design. <br />Page 122 of 145
