No additional impervious surface to be added. This project qualies as a Small Project per the Stormwater Flow Chart, however, the central section of this parcel (not including the proposed build site) is considered a "Moderate" Landslide Hazard area. I am inquiring what stormwater steps will be necessary with that in mind. Do we need an engineer to come up with a drainage plan? 2) There is a discrepancy with the North property line.

No additional impervious surface to be added. This project qualies as a Small Project per the Stormwater Flow Chart, however, the central section of this parcel (not including the proposed build site) is considered a "Moderate" Landslide Hazard area. I am inquiring what stormwater steps will be necessary with that in mind. Do we need an engineer to come up with a drainage plan? An engineered stormwater plan is required if the applicant is proposing to alter the existing stormwater drainage on the subject property. If the applicant is proposing to introduce additional stormwater (associated with an additional structure) to the existing drianage pipe, a licensed stormwater engineer shall review the proposal and submit a engineered stormwater letter and/or engineered stormwater plan verifying the existing drainage pipe can manage all impervious surfaces proposed. Jeerson County will also request that the professional geologist address the proposed additional stormwater dispersion onto the steep slope and into the erosion hazard area. This review can be submitted as an addendum of the existinng geological hazard assessment. 2) There is a discrepancy with the North property line. The "Aker Short Plat" from 1988 shows the Northwest property pin to be approx 25' south of what the Land Survey from 2006 is showing based o of a Quit Claim Deed recording (File No: 513887).

I anticipate some turbulence with applying for the building permit with this in mind, and would like to know how to best resolve and avoid issues later. The most recent legally established land division action on the property will determine the current property lines. According to the property history, a Boundary Line Adjustment (SUB200700031) was approved in 2007. It is highly recommended to ask the Jeerson County Assessor's Oce if the 2006 survey is the most recent survey conducted for the property, and if this is the survey approved with SUB200700031. Creating and altering private easement areas are a private legal matter. 10/12/22, 1:42 PM Online Appointment Scheduling Software :: Free Scheduler for Appointments https://secure.acuityscheduling.com/appointments/view/906035343?print=1 4/6 3) Is a Geological Hazard Assessment provided by a Geotech with conclusions and recommendations for the tree removal and drainage option pertaining to the landslide or erosion hazard sucient to address building with the parcel having a section that is a "Moderate" Landslide Hazard Area? And will a Geological Hazard Assessment provided also help with the Stormwater requirement? The Geological Hazard Assessment must contain language addressing the proposed new structure and/or development footprint in the landslide hazard area, and any stormwater or construction recommendations associated with the proposed new structure. If it currently does not contain such language, an addendum shall be required in conjunction with a building permit application. See the answer for question #1 regarding stormwater review.

No special report is required for the proposal. Aquifer Recharge Areas in Jeerson County are characterized by porous geological formations that allow percolation of the surface water into the soils and the underlying zone of saturation. Aquifers are geologic formations that contain sucient saturated permeable material to yield signicant quantities of water to wells and springs. Aquifers serve as the source of drinking water within most of the rural portions of Jeerson County. Critical Aquifer Recharge Areas may require special protection measures to mitigate water quality degradation. The submitted proposal does not require additional aquifer protection measures. However, during construction the project shall follow the Best Management Practices (BMPs) and facility design standards as identied and dened in the Stormwater Management Manual for the Puget Sound Basin.

An Engineered Stormwater Plan will be required if the project meets any of the criteria below: - Sites with greater than 15% slopes may require applicants hire a geologist to recommend if a drainage method is appropriate. - If you cannot do full dispersion on parcels larger than 5 acres, engineering is required. - Discharging directly to a marine water via tight line must be engineered. - Other site constraints (i.e. critical areas, setbacks, lot size, etc.) that would require engineered consultation and design.
