Re: MLA10-00385 Stormwater Permit to retrofit Balsa Way drainage Public Works Department fees Dear Mr. Eades: This follows up on my letters dated August 12, and November 30,2011 and my phone messages on February 13 and March 21,2012. Public Works reviewed the storm drainage plan for your project in October 2010. You will recall that Public Works responded expeditiously to assist you to correct a serious drainage problem that was threatening residences and septic drainfields. While construction was in progress, revisions to the drainage system were proposed. Revised plans have not been submitted to Public Works. The project engineer needs to submit revised plans to Public Works. Depending on the revisions that were made,the plans may also need to be reviewed by the Environmental Health Department to ensure that the septic permit for Parcel F remains valid.After construction has been completed,the project engineer needs to submit a letter to Public Works certifying that construction conforms to the revised plans. In order to meet the requirements of the Jefferson County Unified Development Code and ensure that the drainage facilities are maintained,Jefferson County requires project proponents to enter into a Stormwater Management Facility Maintenance Agreement with the County. Public Works sent you a copy of its Model Agreement with the suggestion that you review it with your attorney, share it with the other parcel owners,and revise it as appropriate. The Agreement should refer to recorded easements that authorize the construction and maintenance of the facilities and identify the parties that will be responsible for maintenance. Prior to final signoff on your project by Jefferson County, the Agreement needs to be reviewed by Public Works and filed with the County Auditor. Until these actions have been completed, you and the other affected property owners will not have assurance that the drainage problem that instigated this project has been solved. Attached is an updated bill for Public Work's fees for the project. Please remit the amount due. Please contact me if you have any questions or if I can be of assistance. erely, Jam s W.

BLD10-368 Hi Jay When I first reviewed your plan I took your location of the storm drain and transposed it onto the various septic system as-built drawings. One version of this showed a storm drain to be up against a septic drainfield. Jim Eades came into my office shortly after that and explained how the "greenbelt" factored into the two drawings and that there shouldn't be any setback issues with this portion of the storm drain. When I noticed the construction had started I did make a courtesy stop by the project to see how things really laid out. The trench that was excavated is not up against the drainfield and appeared to be in the 30' range. I did not take any measurements as I did not take the time to locate the reserve drainfield, however, I confirmed the storm drain is not up against the septic system as I originally feared. It is my understanding that Nathan Cleaver is aware of this situation. In the end any open ditch that is down slope from a primary or reserve drainfield must be 30' away. Existing reserve drainfield areas can be moved by Nathan if necessary, this may or may not require an application from our office. Our office can't sign off on this project until the above is confirmed.

Dear Randy, 10/24/2011 Page 2 of 2 On Friday, October 21, 2011, I reviewed the progress on the stormwater conveyance system and infiltration pond being constructed by the Eades. The plan is to route storm water runoff away from some existing residences and drain fields. Our plans indicate using 12 pipe at the end of Eisenbeis Avenue. The Eades indicated that you have reviewed the infiltration ditch constructed and have approved the setback from the drainfield and reserve areas for the two lots at the end of the road. Please confirm that the installed infiltration trench meets the required setback. If the setback is not sufficient, then the pipe will need to be installed, per the approved design. Regards, Jay S.

After an expedited review I noticed some setback issues with the proposed stormwater system and existing septic systems. If the stormwater system is installed as show on the revised plot plan drawn 10/21/10 two existing in use septic systems will become invalid and require additional permitting to correct issues this stormwater system will cause. Specifically the issues are: • Existing primary and reserve drainfields are not shown accurately. • Any down slope drainage ditches or drainage swales must be located 30 feet below a primary or reserve drainfield area. • Can not install a stormdrain tight line through a primary and reserve area. A septic system designer needs to be contacted to address these and other possible issue that this project may create. Further review by health will require a review fee.

Comparing these two drawings with the final survey of the boundary line adjustment(AFN515101) we determined that the septic system is indeed located 30' from the east property line as shown by Nathan. This 30' accounts for the HWY 20 corridor buffer as shown on the survey. This 30' is a part of lot"F." Nathan shows this as "Greenbelt." The approved stormwater plan by 4 Seasons Engineering does not show that lot"F" includes the 30' buffer. This puts the storm drain 30' from the true east property line and therefore up against the septic system. Installation of the storm drain in this location will invalidate the septic system that serves the residence on lot"F." I recently visited the property and believe this not your intension, as I noticed that you have a temporary drainage system installed along what appears to be the true east property line (along the HWY 20 buffer.) Your engineered stormwater plan needs to be revised. Lot"H" also has issues as you know. The approved stormwater plan shows an open drainage swale between lots "H"&"G." This open drainage needs to be 30' below the reserve drainfield of lot"H." Installation of an open drainage in this location will invalidate the septic permit that serves the residence on lot"H." Your solution was to tight line this section reducing the setback to 10.' This is acceptable however;the approved plan needs to be revised to reflect this. I am copying this letter to the effected property owners should this stormwater system be installed as designed.

The applicant will need to document the easements to Public Works prior to preparation of the Stormwater Management Facility Maintenance Agreement. FINDINGS: 1.) The Administrator finds that this application complies with applicable provisions of the Unified Development Code,all other applicable ordinances and regulations,and is consistent with the Jefferson County Comprehensive Plan and Land Use map. 2.) The proposal is intended to retrofit an existing drainage system by collecting runoff from the adjoining property to the south (Assessor's Parcel Number 001-212-008)that periodically inundates properties on Balsa Way and conveying it by means of Swale and 12 inch diameter storm drainage pipe to an infiltration facility located on an adjoining lot to the north (Assessor's Parcel Number 948-603-201). 3.) This drainage problem was the subject of an Action Request to Public Works Initiated by Nancy Rody, 159 Louisa Street(Balsa Way on June 10, 2010. Public Works determined that the problem was not attributable to runoff from public roads or from the Eade's development on Louisa Street and Balsa Way. 4.) The Jefferson County Unified Development Code, Section 18.30.070 Stormwater Management Standards adopts the standards and minimum requirements of the Washington Department of Ecology Stormwater Management Manual for Western Washington. 5.) The applicants have submitted a Stormwater Improvement Plan for the proposal prepared by 4 Seasons Engineering (October 14, 2010). The Plan states that the improvements have been designed in accordance with the Stormwater Management Manual. Public Works reviewed the Plan and discussed it with 4 Seasons which clarified and revised aspects if the Plan in an email and attachment to Public Works dated October 22, 2010. 6.) A natural drainage channel on the adjoining property to the south has been impounded by a 7 foot high earthen dam that was constructed by the applicants in 2006. The structure has an 8 inch outlet pipe with a 2 inch orifice cap. This structure was not permitted by Jefferson County or a State agency. The Stormwater Plan states that it does not comply with the State requirements for height or construction materials or methods. The Plan recommends either the structure be removed or its height be reduced to 4 feet and the orifice cap on the outlet pipe be removed. It also recommends that if the structure is kept in place, it should be inspected by a geotechnical engineer. The Stormwater Plan calculations and recommended design of the conveyance and infiltration facilities assume that the height of the structure will be reduced and the orifice cap will be removed. The disposition of this structure is not the responsibility of Public Works. This memo does not review or authorize its construction or modification.

During periods of late winter heavy rains,considerable stormwater passes through the yards of the newly constructed homes. Balsa Way and the associated residences were constructed beginning in 2006 in a previously platted,but undeveloped area. To improve the conveyance of stormwater around the homes,a new rock lined drainage swale, 12" culvert,and catch basins are proposed. The outflow of the new conveyance system will direct the stormwater to a shallow infiltration depression on the lot to the north. Our assessment of the existing conditions included review of topography,drainage patterns, soils, ground cover,and existing development using aerial photography,lidar topographic mapping, and on site observations,including soil test pits. The analysis and design of the stormwater improvements was done in accordance with the latest version of the Stormwater Management Manual for Western Washington. Drainage Basin Description: The proposed project is in the Glen Cove area south of Port Townsend, in Sections 16 and 21, Township 30 North,Range 1 West. The residential area at the end of Balsa Way is a moderately sloping area west of Highway 20, accessed from Louisa Street. The residential area was platted many years ago,but only recently developed by the Eades. The Eades family also owns the undeveloped property to the south, as well as a number of remaining undeveloped lots in the area. Average annual rainfall at this site is approximately 25 inches per year. The ground elevation at this location is approximately 250 feet above sea level. A natural drainage channel from the south previously dispersed overland onto the gently sloping area at the end of Balsa Way. The drainage is a small,forested valley on the edge of a gently sloping plateau. An earthen dam was constructed across the natural drainage channel in 2006. The earthen dam is about 7 feet high and topped with crushed roofing tiles. An 8 inch outlet pipe with a 2 inch diameter orifice drains the impounded area to the natural drainage below. The plateau to the south is undulating,very gently sloping and extends approximately 1/2 a mile before reaching the natural drainage divide. The plateau contains a mixture of forested and lightly developed rural properties just west of Highway 20. Undeveloped areas of the basin are forested with second growth fir,cedar, and alder,with grass,salal,and native ground cover. Many small depressions exist with signs of seasonal ponding and vegetation tolerant of hydric soil conditions. A small area of light industrial properties also drains into the natural drainage with a 24 inch concrete culvert across Highway 20. Soils of the plateau area,and the natural drainage channel are mapped mostly as Clallam gravelly sandy loam,according to the Soil Survey of Jefferson County. The Clallam soils 2 , typically consist of 20 to 40 inches of well drained soils over a slowly permeable cemented layer. Permeability would typically be moderate to the glacial till layer,but very slow through it, causing a shallow seasonal water table during the rainy season. A portion of the area, including the natural drainage is mapped as Hoypus gravelly loamy sand,but soil test pits confirmed the presence of compact till layers similar to Clallam soils. Soil test pits were dug in the area of the natural drainage channel just south of the Balsa Way neighborhood. The soils contained layers of sandy gravel over compact glacial till at a depth of about 5 feet. Below Balsa Way,the drainage naturally dispersed out onto a lower plateau of gently sloping sandy soils,where it appears to have naturally infiltrated. Overflow from the area would naturally have flowed toward a shallow ditch along the west side of Highway 20. The existing ditch does not have a well defined bed,indicating that the majority of runoff from the area naturally infiltrates into the sandy soils. The Soil Survey indicates that the area contains Dick loamy sand,which is typically very deep and somewhat excessively drained sand formed in glacial outwash. Permeability of these types of soils is typically rapid and the hazard of water erosion is slight to moderate. Soil test pits confirmed the presence of deep, sandy soils in the area. Two test pits were dug, confirming the presence medium fine sand down to depths of over 7 feet. Proposed Improvements: Intermittent flooding of the properties at the east end of Balsa Way in the past few winters, illustrated the need for a storm drainage system. The natural drainage channel has been altered by the grading and home construction. The roadway ditch along Balsa Way ends at the last ririxrcaxrav ixrith nit a enlvprt to heln maintain the natural drainage. Y � Stormwater controls could include preserving portions of the site, such as the natural drainage channel as native vegetation,and incorporating smaller stormwater retention areas throughout the development. Earthen dams over 6 feet high require a geotechnical design,are required to be keyed into the native ground,and compacted to proper specifications. The existing dam appears to be constructed of lightly compacted native earth and discarded roofing tiles without an adequate spillway. In the event of an overtopping storm,the earthen dam could fail and send a large surge of water down towards the residences below. We recommend that at a minimum,the orifice cap on the outlet pipe be removed and the vertical riser cut down to 4 feet above the pond bottom to restore the free flow of the natural drainage. Removal of the earthen dam or lowering the top to a maximum of 4 feet should also be considered. If kept in place,the earthen dam should be inspected by a geotechnical engineering expert to verify whether the construction is adequate for existing or future use as a stormwater impoundment. Hydrologic Modeling: The Western Washington Hydrology Model was used to model stormwater runoff and size the stormwater control measures. The predevelopment condition was analyzed based on soil and surface types from soil survey maps,aerial photography,and field verification. The computer model used a single basin with the attributes of the existing conditions with outflow to an infiltration swale area of wooded terrain. The infiltration swale was assumed to have an infiltration rate of 20 inches per hour,based on the soil survey and experience with similar sandy soils. Approximate dimensions of the predevelopment infiltration area are 140'wide by 300' long with a natural slope of 8%. The post development condition was modeled as a single basin with outflow to a constructed infiltration basin. The infiltration basin was modeled as a 3 foot deep trapezoidal pond with 2:1 side slopes and a total surface area of 1400 square feet. The proposed basin will be sculpted to appear more natural, but retain the modeled surface area. The existing impoundment on the Eades'property south of Balsa Way was also modeled using the Western Washington Hydrology Model. The predevelopment condition was analyzed for all area of the basin upstream of the impoundment in its existing state. The postdevelopment condition was analyzed for development of 7.3 acres of the Eades'property with 30% impervious and 70%lawn area. The impounded area was modeled as a trapezoidal pond with a total depth of 5 feet and 6:1 side slopes. The required surface area of the pond was approximately 35,000 square feet with a total volume of about 2 acre feet. Based on lidar contours of the natural drainage,the existing impoundment has approximately the same surface area. Exact layout and configuration of the future development could be significantly different from that assumed,and a stormwater plan addressing the specifics of the development will be required at the time. The impoundment also detains a significant amount of offsite runoff which is neither required or recommended. 4 r r A map of the predevelopment and postdevelopment basin areas with lidar topography and aerial photography from Jefferson County GIS is included in Appendix A. A spreadsheet of the predevelopment and postdevelopment basin sizes, surface conditions is included in appendix B. Results of the WWHM computer modeling are included in Appendix C. Stormwater Conveyance Analysis: Flow capacity of the proposed pipe and drainage swale was modeled in an Excel spreadsheet using the step backwater method based on maximum flow for the 25 year storm based on the WWHM model results. A 12 inch smooth wall corrugated polyethylene pipe is sufficient for conveyance of the stormwater. The spreadsheet is included in Appendix D. In addition, some minor changes to the home at the southeast end of Balsa Way are recommended. The grading around the back of the house aggravated the infrequent flooding and previously resulted in stormwater pouring through the foundation vents and accumulating in the lowest portion of the crawl space. We recommend that vent wells be added along the back of the house and that a drain pipe be installed from the lowest portion of the crawl space. Summary: The proposed stormwater improvements for the east end of Balsa Way are designed to restore the natural drainage disturbed by the recent grading and home construction. Analysis and sizing of the facility has been performed using the latest version of the Stormwater Management Manual for Western Washington and the Western Washington Hydrology Model. The proposed conveyance system is designed to protect the existing homes from infrequent flooding. The existing earthen dam and impoundment may be suitable for stormwater control of future development of the property south of Balsa Way. However, it does not appear to have been constructed according to current standards. We recommend that at a minimum,the orifice cap on the outlet pipe be removed at this time and the dam inspected by a geotechnical engineering expert. Maintaining the free flow of the natural drainage channel and providing separate stormwater controls for future development would be more appropriate. Extreme storms,uncontrolled development,or alteration of natural drainage patterns could exceed the capacity of the proposed stormwater conveyance system. In this event, stormwater would most likely back up and cause temporary flooding of the homes and yards of the homes in this area,as has happened previously. Care should therefore be taken to ensure that adequate stormwater detention facilities are constructed when approving development within the drainage basin. Diversion of additional areas to this drainage basin is not recommended. 5 Y Appendix A Basin Maps Y ' I J r .. j� i 1�• 9 11 M �w� � R y 4r f as •'' c . +w/ b CI j •"11.:-.4...•;` r 5 • MMYnM i'f ,i }'b°"':.., f.,y ..' f• 1 tt l • �w w,u , { a • I I y r; '2 J`7 .r s t ..*Pi' r ,r ' 1 f6 4kw, ...� �w . . ,. , tiles �.p ir..... � k F ....„.,..... :, ,. ,.„.„,,.

Thank yoga for contacting me With your questions about the Stotmnwater Improvement Plan for James and Marsha FA4des. In our phone conversation,you expressed concern about the infiltration tate used in our design of ttte infiltration basin at the end of the stormwater conveyance system. The proposed stormwater conveyance system preserves the natural drainage pattern and dischar acs into a forested area underlain by sandy soils,which slopes toward the state highway. The infiltration basin was designed to restore infiltration capacity lost when the natural drainage pattern was altered. I have reviewed the infiltration rate used,and the computer modeling of the stormwater routine and infiltration design. The soils observed daring our site investigation of the infiltration area were very uniform, homogenous sand,which will likely have a much higher infiltration rate than that assumed by the textural analysis guidelines of the Storrmvater Management Manual for Western Washington. Unfortunately,a Pilot Infiltration Test, as described in Volume III - Appendix I7 of the manual, is cost prohibitive for a project of this size. The Soil Survey of Jefferson, County Area. Washington cites an infiltration rate of 6.0 to 20.0 inches per hour for soils in. this area. In my professional judgment,an infiltration rat'of 8 inches per hour as recommended in Table 3.7 in the manual,with the minimum recommended reduction factor of 0.5 is a very conservative estimate for the soils and the application of this project. ject. Results of the computer modeling with the revised infiltration rue indicate that an infiltration basin with a surface area of 2500 square feet is sufficient. I have revised our report_the computer model,and plan sheets. Please review the amended report and plans and contact me if von have any further questions or concerns.

During periods of late winter heavy rains, considerable stormwater passes through the yards of the newly constructed homes. Balsa Way and the associated residences were constructed beginning in 2006 in a previously platted,but undeveloped area. To improve the conveyance of stormwater around the homes, a new rock lined drainage swale, 12" culvert, and catch basins are proposed. The outflow of the new conveyance system will direct the stormwater to a shallow infiltration depression on the lot to the north. Our assessment of the existing conditions included review of topography, drainage patterns, soils, ground cover, and existing development using aerial photography, lidar topographic mapping, and on site observations, including soil test pits. The analysis and design of the stormwater improvements was done in accordance with the latest version of the Stormwater Management Manual for Western Washington. Drainage Basin Description: The proposed project is in the Glen Cove area south of Port Townsend, in Sections 16 and 21, Township 30 North, Range 1 West. The residential area at the end of Balsa Way is a moderately sloping area west of Highway 20, accessed from Louisa Street. The residential area was platted many years ago,but only recently developed by the Eades. The Eades family also owns the undeveloped property to the south, as well as a number of remaining undeveloped lots in the area. Average annual rainfall at this site is approximately 25 inches per year. The ground elevation at this location is approximately 250 feet above sea level. A natural drainage channel from the south previously dispersed overland onto the gently sloping area at the end of Balsa Way. The drainage is a small, forested valley on the edge of a gently sloping plateau. An earthen dam was constructed across the natural drainage channel in 2006. The earthen dam is about 7 feet high and topped with crushed roofing tiles. An 8 inch outlet pipe with a 2 inch diameter orifice drains the impounded area to the natural drainage below. The plateau to the south is undulating,very gently sloping and extends approximately'A a mile before reaching the natural drainage divide. The plateau contains a mixture of forested and lightly developed rural properties just west of Highway 20. Undeveloped areas of the basin are forested with second growth fir, cedar, and alder,with grass, salal, and native ground cover. Many small depressions exist with signs of seasonal ponding and vegetation tolerant of hydric soil conditions. A small area of light industrial properties also drains into the natural drainage with a 24 inch concrete culvert across Highway 20. Soils of the plateau area, and the natural drainage channel are mapped mostly as Clallam gravelly sandy loam, according to the Soil Survey of Jefferson County. The Clallam soils typically consist of 20 to 40 inches of well drained soils over a slowly permeable cemented layer. Permeability would typically be moderate to the glacial till layer,but very slow 2 through it, causing a shallow seasonal water table during the rainy season. A portion of the area, including the natural drainage is mapped as Hoypus gravelly loamy sand,but soil test pits confirmed the presence of compact till layers similar to Clallam soils. Soil test pits were dug in the area of the natural drainage channel just south of the Balsa Way neighborhood. The soils contained layers of sandy gravel over compact glacial till at a depth of about 5 feet. Below Balsa Way, the drainage naturally dispersed out onto a lower plateau of gently sloping sandy soils, where it appears to have naturally infiltrated. Overflow from the area would naturally have flowed toward a shallow ditch along the west side of Highway 20. The existing ditch does not have a well defined bed, indicating that the majority of runoff from the area naturally infiltrates into the sandy soils. The Soil Survey indicates that the area contains Dick loamy sand,which is typically very deep and somewhat excessively drained sand formed in glacial outwash. Permeability of these types of soils is typically rapid and the hazard of water erosion is slight to moderate. Soil test pits confirmed the presence of deep, sandy soils in the area. Two test pits were dug, confirming the presence medium fine sand down to depths of over 7 feet. Proposed Improvements: Intermittent flooding of the properties at the east end of Balsa Way in the past few winters, illustrated the need for a storm drainage system. The natural drainage channel has been altered by the grading and home construction. The roadway ditch along Balsa Way ends at the last driveway with out a culvert to help maintain the natural drainage. A new drainage system with a mixture of rock lined drainage swales and 12 inch culverts is proposed to direct the natural drainage around the existing homes and yards. The storm drain system will daylight to a shallow infiltration basin a block to the north, on a residential lot also owned by the Eades. Any overflow from the infiltration basin will be directed overland toward the natural drainage,which leads toward the highway. In addition,to the proposed storm drainage improvements, the existing impoundment of the natural drainage channel was analyzed. The property which contains the dammed impoundment is currently an undeveloped, forested area of approximately 17.5 acres, also owned by the Eades. The impoundment was analyzed for its' impacts on stormwater flow and the future development of the property. Approximately 7.3 acres of the property appears to drain to the impounded area. Future plans for the property include the development of residential lots and possibly some park area. The impounded area is of adequate size to be suitable for stormwater control from a future development. However, the earthen dam and outlet pipes would need to be reconstructed to meet state and local codes. Maintaining the free flow of the natural drainage channel and providing separate stormwater controls for the developed area would be more appropriate. Stormwater controls could include preserving portions of the site, such as the natural drainage channel as native vegetation, and incorporating smaller stormwater retention areas throughout the development. 3 Earthen dams over 6 feet high require a geotechnical design, are required to be keyed into the native ground, and compacted to proper specifications. The existing dam appears to be constructed of lightly compacted native earth and discarded roofing tiles without an adequate spillway. In the event of an overtopping storm,the earthen dam could fail and send a large surge of water down towards the residences below. We recommend that at a minimum,the orifice cap on the outlet pipe be removed and the vertical riser cut down to 4 feet above the pond bottom to restore the free flow of the natural drainage. Removal of the earthen dam or lowering the top to a maximum of 4 feet should also be considered. If kept in place, the earthen dam should be inspected by a geotechnical engineering expert to verify whether the construction is adequate for existing or future use as a stormwater impoundment. Hydrologic Modeling: The Western Washington Hydrology Model was used to model stormwater runoff and size the stormwater control measures. The predevelopment condition was analyzed based on soil and surface types from soil survey maps, aerial photography, and field verification. The computer model used a single basin with the attributes of the existing conditions with outflow to an infiltration swale area of wooded terrain. The infiltration swale was assumed to have an infiltration rate of 8 inches per hour,based on the soil investigation and the infiltration rates from the Stormwater Management Manual for Western Washington. Approximate dimensions of the predevelopment infiltration area are 140'wide by 300' long with a natural slope of 8%. The post development condition was modeled as a single basin with outflow to a swale and a constructed infiltration basin. Infiltration rate used in the model was 8 inches per hour. Based on the homogeneity of the sandy soils observed in the test pits, a reduction factor of 0.5 is suitable. The infiltration basin was modeled as a 3 foot deep trapezoidal pond with 2:1 side slopes and a total surface area of 2500 square feet. Retained depth was 2 feet with an overflow weir. The proposed basin will be sculpted to appear more natural,but retain the modeled surface area. The existing impoundment on the Eades'property south of Balsa Way was also modeled using the Western Washington Hydrology Model. The predevelopment condition was analyzed for all area of the basin upstream of the impoundment in its existing state. The postdevelopment condition was analyzed for development of 7.3 acres of the Eades'property with 30% impervious and 70% lawn area. The impounded area was modeled as a trapezoidal pond with a total depth of 5 feet and 6:1 side slopes. The required surface area of the pond was approximately 35,000 square feet with a total volume of about 2 acre feet. Based on lidar contours of the natural drainage,the existing impoundment has approximately the same surface area. Exact layout and configuration of the future development could be significantly different from that assumed, and a stormwater plan addressing the specifics of the development will be required at the time. The impoundment also detains a significant amount of offsite runoff which is neither required or recommended. 4 A map of the predevelopment and postdevelopment basin areas with lidar topography and aerial photography from Jefferson County GIS is included in Appendix A. A spreadsheet of the predevelopment and postdevelopment basin sizes, surface conditions is included in appendix B. Results of the WWHM computer modeling are included in Appendix C. Stormwater Conveyance Analysis: Flow capacity of the proposed pipe and drainage swale was modeled in an Excel spreadsheet using the step backwater method based on maximum flow for the 25 year storm based on the WWHM model results. A 12 inch smooth wall corrugated polyethylene pipe is sufficient for conveyance of the stormwater. The spreadsheet is included in Appendix D. In addition, some minor changes to the home at the southeast end of Balsa Way are recommended. The grading around the back of the house aggravated the infrequent flooding and previously resulted in stormwater pouring through the foundation vents and accumulating in the lowest portion of the crawl space. We recommend that vent wells be added along the back of the house and that a drain pipe be installed from the lowest portion of the crawl space. Summary: The proposed stormwater improvements for the east end of Balsa Way are designed to restore the natural drainage disturbed by the recent grading and home construction. Analysis and sizing of the facility has been performed using the latest version of the Stormwater Management Manual for Western Washington and the Western Washington Hydrology Model. The proposed conveyance system is designed to protect the existing homes from infrequent flooding. The existing earthen dam and impoundment may be suitable for stormwater control of future development of the property south of Balsa Way. However, it does not appear to have been constructed according to current standards. We recommend that at a minimum,the orifice cap on the outlet pipe be removed at this time and the dam inspected by a geotechnical engineering expert. Maintaining the free flow of the natural drainage channel and providing separate stormwater controls for future development would be more appropriate. Extreme storms,uncontrolled development, or alteration of natural drainage patterns could exceed the capacity of the proposed stormwater conveyance system. In this event, stormwater would most likely back up and cause temporary flooding of the homes and yards of the homes in this area, as has happened previously. Care should therefore be taken to ensure that adequate stormwater detention facilities are constructed when approving development within the drainage basin. Diversion of additional areas to this drainage basin is not recommended. 5 Appendix A Basin Maps — \ t- a fit._= ` v: `' r pp 22° 1.70 7 1,.r �� ,.i ,, \ ,..u_ �� may.., e ,f. � , ,n 1 7 IIPII i y r j`��i�,a 1 -,r i ce ' L. 5 � ,, `°� 1� \ 0,-1 ' EX 24 Co I CULVERT �4� � - E ISTING DAM �` ',7k -_ 73l ;'� 1 _�"'`` MBANKMENT 4„-\41 ,1/4k, _-- t. >, � °-.° �, 9°;AC rp is a.,.> 1-"f O. ti q� k. �^ i i ri �3 ' 170 3� ''�..� :''is `°.,,,,,,,, ,. ,, .v= ', s „, i r ,.,,,: : % 1 s r.

Pearson,Project Manage DATE: a DATE: October 22, 2010 L 9� RE: MLA10-00385 Emergency Stormwater Repair; Balsa Way James and Marsha Eades, applicants The Public Works Department has reviewed the Stormwater System Improvement Plan(4 Season Engineering, October 14, 2010) for the proposal and notes the following: • The proposal is intended to retrofit an existing drainage system by collecting runoff from the adjoining property to the south(Assessors Parcel Number 001212008)that periodically inundates properties on Balsa Way and conveying it by means of a Swale and 12"diameter storm drainage pipe to an infiltration facility located on an adjoining lot to the north(Assessors Parcel Number 948603201). • This drainage problem was the subject of an Action Request to Public Works initiated by Nancy Rody, 159 Louisa Street(Balsa Way)on June 10,2010. Public Works determined that the problem was not attributable to runoff from public roads or from the Eades' development on Louisa Street and Balsa Way. • The Jefferson County Unified Development Code, Section 18.30.070 Stormwater Management Standards adopts the standards and minimum requirements of the Washington Department of Ecology Stormwater Management Manual for Western Washington. • The applicants have submitted a Stormwater Improvement Plan for the proposal prepared by 4 Seasons Engineering(October 14,2010). The Plan states that the improvements have been designed in accordance with the Stormwater Management Manual.Public Works reviewed the Plan and discussed it with 4 Seasons which clarified and revised aspects of the Plan in an email and attachment to Public Works dated October 22,2010. . • A natural drainage channel on the adjoining property to the south has been impounded by a 7' high earthen dam that was constructed by the applicants in 2006.The structure has an 8"outlet pipe with a 2"orifice cap.This structure was not permitted by Jefferson County or a State agency. The Stormwater Plan states that it does not comply with State requirements for height or construction materials or methods. The Plan recommends either that the structure be removed or its height be reduced to 4' and the orifice cap on the outlet pipe be removed. It also Eades Stormwater Repair Balsa Way } recommends that if the structure is kept in place, it should be inspected by a geotechnical engineer. The Stormwater Plan calculations and recommended design of the conveyance and infiltration facilities assume that the height of the structure will be reduced and the orifice cap will be removed. The disposition of this structure is not the responsibility of Public Works. This memo does not review or authorize its construction or modification. • The applicants shall implement the Stormwater Management Improvement Plan as revised by 4 Seasons Engineering on October 22, 2010. The work shall be conducted under the direction of a licensed engineer. • After the work has been completed,the applicants shall submit a letter to Public Works from the project engineer certifying that the stormwater management facilities have been constructed as per the Stormwater Plan. • In order to meet the requirements of the Jefferson County Unified Development Code and the Washington Department of Ecology Stormwater Management Manual for Western Washington Minimum Requirement#10 Operation and Maintenance and to ensure that the approved • stormwater management facilities are appropriately maintained for the life of the project, Jefferson County requires the applicant to enter into a Stormwater Management Facility Maintenance Agreement with the County. Public Works will send a copy of the Agreement that has been signed by the Public Works Director to the applicant.Prior to final project approval, the applicant shall sign the Agreement before a notary and file it with the Jefferson County Auditor. • The proponent shall pay all costs related to Public Works review of the Stormwater Improvement Plan, any site inspections,communications,and preparation of the Stormwater Management Facility Maintenance Agreement. In accordance with the Jefferson County Public Works Department Fee Schedule,the Department's fee is currently$65 per hour. c: Paul Walters, Jefferson County Public Works Department Terry Barnet, Maintenance Superintendent, WSDOT, 1707 South C Street,Port Angeles, WA 98363 Jim Eades, 2911 Sherman Street, Port Townsend, WA 98368 Nancy Rody, 159 Louisa Street, Port Townsend, WA 98368 Ryan Barnard, 155 Louisa Street, Port Townsend, WA 98368 Jay Gordon, 153 Louisa Street, Port Townsend, WA 98368 Eades Stormwater Repair Balsa Way Page 1 of 1 Michelle Farfan From: Jim Pearson Sent: Monday, October 25, 2010 3:24 PM To: Michelle Farfan Cc: partch_fourse @olypen.com Subject: MLA10-00385 Stormwater Repair; James and Marsha Eades, Balsa Way Michelle, The following should be added to my comments dated October 22, 2010: The applicant's engineer shall provide an operations and maintenance manual that is consistent with Stormwater Management Manual, Minimum Requirement#10 Operations and Maintenance to the applicant and Public Works.

The size determines whether a Stormwater Site Plan is required in conjunction with a stand-alone stormwater management permit application, building permit application, or other land use approval application that involves stormwater review. The basic information will also be helpful for completing a Stormwater Site Plan,if required. PARCEL SIZE(I.E.,SITE) Size of parcel acres An acre contains 43,560 square feet. Multiply the acreage by this figure. Size of parcel in square feet sq/ft ,_ v Land-disturbing activity is any activity that results in movement of earth, or a change in the existing soil cover(both vegetative and non-vegetative) and/or the existing soil topography. Land disturbing activities include, but are not limited to clearing, grading, filling, excavation, and compaction associated with stabilization of structures and road construction. Native vegetation is vegetation comprised on plant species, other than noxious weeds,that are indigenous to the coastal region of the Pacific Northwest and which reasonably could have been expected to naturally occur on the site. Examples include species such as Douglas fir,western hemlock,western red cedar, alder, big-leaf maple, and vine maple;shrubs such as willow,elderberry,salmonberry, and salal; herbaceous plants such as sword fern,foam flower,and fireweed. LAND DISTURBING ACTIVITY,CONVERSION OF NATIVE VEGETATION,AND VOLUME OF CUT/FILL Calculate the total area to be cleared, graded,filled, Answer the following two questions related to excavated,and/or compacted for proposed development conversion of native vegetation: project.

A hard surface area which causes water to run off the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. Common impervious surfaces include, but are not limited to roof tops, walkways, patios, driveways, parking lots or storage areas, concrete or asphalt paving, gravel roads, packed earthen materials, and oiled, macadam or other surfaces which similarly impede the natural infiltration of stormwater.

The following questions will help determine whether the proposed project is considered development or redevelopment. DEVELOPMENT v. REDEVELOPMENT Divide the total existing impervious surface above by the size of the parcel and convert to a percentage: -6,70 Does the site have 35%or more of existing impervious surface? Circle: Yes No FURTHER INSTRUCTIONS: If the answer is yes, the proposal is considered redevelopment and the attached Figure 2 should be used to determine the applicable Minimum Requirements. If the answer is no, the proposal is considered new development and the attached Figure 1 should be used. At this juncture, the applicant should refer to the applicable Flow Chart to determine the Minimum Requirements for stormwater management. DCD staff will help verify the classification of the project and the application requirements. For proponents of "small" projects who must comply only with Minimum Requirement #2—Construction Stormwater Pollution Prevention—an additional submittal is not required. The proponent is responsible for employing the 12 Elements to control erosion and prevent sediment and other pollutants from leaving the site during the construction phase of the project. Pick up the Construction Stormwater Pollution Prevention (SWPP) Best Management Practices (BMPs) Packet. Proponents of"medium" projects—those that must meet only Minimum Requirements #1 through #5—and for "large" projects—those that must meet all 10 Minimum Requirements—are required to submit a Stormwater Site Plan. DCD has prepared a submittal template of a Stormwater Site Plan, principally for rural residential projects. Complete the template in the Stormwater Site Plan Instructions and Submittal Template or prepare a Stormwater Site Plan using the step-by-step guidance in the Stormwater Management Manual.
