Photo Documentation MSA • MCCullough Residence Expansion Mitigation • Planting Plan 2 1. Introduction' The proposal described herein is for the construction of an uncovered deck adjoining an existing residence within the central portion of Parcels 701184009 and 701184018 in Jefferson County, Washington (Figure 1). An Ordinary High -Water Mark (OHWM) Determination was conducted by Marine Surveys & Assessment (MSA) on April 27' and September 6th, 2018 to determine the marine shore OHWM and substantiate the absence or presence of an estuarine wetland. The marine shore OHWM was identified, delineated, and mapped within the southwestern border of the project site (Figure 2). The standard buffer for marine shores, in all shoreline environments, is a minimum of 150 -feet (Jefferson County Code, Shoreline Master Program, and 18.25.270 (4)(e)(i) — Standard Buffer). A ten - foot building setback was also established landward of the standard buffer (18.25.270 (4)(d) — Building Setbacks). The 150 -foot buffer, plus ten -foot building setback, extends a total of 160 feet northeast into the area of proposed construction. A Type "Ns" Non -fish bearing stream was identified and delineated. However, the stream OHWM was consider physically separated from the proposed construction area by impervious surface associated with the existing single-family residence (JCC 18.25.270 (4)(c)). A Category II estuarine wetland was also identified and has a 110 -foot buffer (Chapter 18.22 Critical Areas; Table 18.22.330(2): Wetland Categories, Rating Scores and Buffer Widths for Moderate Impact Land Uses). The marine shore buffer extends further into the project site than the Category II estuarine wetland, therefore, the Category II estuarine wetland was not delineated. MSA was informed by the Department of Community Development (DCD) that a letter, describing our findings, and Mitigation Planting Plan are required for the proposed development, which this report satisfies. The proposed expansion of an uncovered deck is approximately 286 ft2 within the marine shore buffer (Figure 4). As stated in Jefferson County Code Shoreline Master Program 18.25.660 (9)(iii), the administrator shall require a planting plan to ensure there is no net loss of shoreline functions for nonconforming lots. A Mitigation Planting Plan shall enhance the shoreline buffer through planting of native vegetation (300 ft2), plus appropriate additional mitigation (Figures 5A and 513). 2. Project Information 2.1 Project Location and Site Description The proposal is located on privately -owned, single -residence property in Jefferson County (Figure 1) Address: 1200 East Quilcene Road, Quilcene, Washington Coun : Jefferson Tax Parcels: #701184018 and 701184009 Property Description: 1100 — Residential — Single Unit and 9100 — Vacant Land PLSS: Section: 18, Township: 27N, Range: 1 W Latitude. Longitude: 47.825'N, -122.851'W Water resource inventory area WRIA : WRIA 17 South (Quilcene-Snow) Water bodies in which work will occur: None Water bodies bordering or adjacent to the project location: Quilcene Bay The project site includes Parcels 701184018 and 701184009, which equal 1.75 acres. Parcel 701184018 consists of a single-family residence, residential lawn, well compacted gravel driveway, ditched stream, and a low energy marine shoreline. Parcel 701184009 consists of a residential lawn, forested area, and low energy marine shoreline. The parcel slopes gradually waterward from 40 feet elevation, throughout the northeastern border, to 10 feet along the southwestern border (Figure 1). The approximate slope of the project site is 8%. Drift logs were present along the marine shoreline as a low energy bulkhead. MSA • McCullough Residence Expansion \litigation • Plnnting Plan 2.2 Proposed Construction Proposed construction includes an uncovered deck adjoining the existing single-family residence on Parcel 701184018. The area of construction currently consists of residential lawn (Figure 3). Current approximate measurements of construction are 656 ft2 The proposed 656 ft2 uncovered deck will be constructed adjoining the southeastern portion of the existing single-family home, which is in the central portion of the project site (Figure 3). Existing structures on the project site include a 1,678 ft2 single-family residence, 212 ft2 combined wood porch, 312 ft2 garage (attached to home), 864 ft2 garage, 288 ft2 carport, and 104 ft2 shed. 2.3 Ordinary -High Water Mark (OHWM) Determination According to WAC 173-22-030 (11)(a)(ii) Clarifying Criteria: (ii) In low energy environments where the action of waves and currents is not sufficient to prevent vegetation establishment below the mean higher high tide, the ordinary high-water mark is coincident with the landward limit of salt tolerant vegetation. Salt tolerant vegetation is defined as vegetation which is tolerant of interstitial soil salinities greater than or equal to 0.5 parts per thousand (ppt) (WAC 173-22-030 (11)(a)(ii)). The salt tolerant vegetation observed within the OHWM was entirely herbaceous and consisted of Chairmaker's club -rush (Schoenoplectus americanus), Garden bird's -foot -trefoil (Lotus corniculatus), Dagger -leaf rush (Juncus ensofolius), Softrush (Juncus effusus), Sow -thistle (Sonchus oleracea), Halberd -leaf orache (Atriplex patula), Western glasswort (Lilaeopsis occidentalis), and Silverweed (Potentilla anserina). Other indicators of the OHWM included the presence of the most recent high tide drift line, which was approximately 1.5 to 2 feet below the OHWM. The OHWM overlapped a drift log bulkhead in some portions of the project site. Two Wetland Determination Data Forms (VSH-1 and VSH-2; Appendix A) were completed to demonstrate the transition between wetland and upland vegetation. A Non -fish bearing stream was observed along the western border of the project site. The marine OHWM mark extended to the elevation within the stream where it entered tidal water. The marine shore OHWM was identified, delineated, and mapped within the southwestern border of the project site (Figure 2). The standard 150 -foot buffer for marine shores was measured landward in a horizontal direction perpendicular to the OHWM of the shoreline water body using geographic information system (GIS) software. A Category II estuarine wetland was also identified, predominantly within the southeastern portion of the project site (Appendix B). Category II estuarine wetlands with moderate impact land uses have a 110 -foot buffer. The marine shore buffer exceeds the Category II estuarine wetland by 40 feet into the project site. Category II estuarine wetlands are smaller than one acre, however, if this estuarine wetland was considered a Category I it would have a 150 -foot buffer which equals the marine shore OHWM buffer, therefore the estuarine wetland was not delineated. 3. Regulatory Framework Nonconforming lot means a legal lot of record in existence prior to the effective date of the current Shoreline Master Program and any amendments thereto, on which it is not possible to construct a structure outside of/landward of the shoreline buffer or which does not otherwise meet the minimum lot size MSA • MCCullough Residence Expansion Mitigation . Planting Plan requirements as set forth in this program. Depth of lot is measured as the distance from the ordinary high- water mark to the inside edge of the frontage setback (JCC 18.25.100 (14)(h)). 3.1 Expansion/Enlargement with a Conditional "C(d)" Use Permit According to JCC 18.25.660 (9): (a) The administrator shall require a conditional use permit for any of the following: (i) Enlargement or expansion of nonconforming single-family residences by the addition of space to the exterior of the main structure or normal appurtenances where the total footprint will increase by more than 25 percent or the expansion/enlargement occurs vertically, laterally or landward, but not waterward, of the structure. (ii) Enlargement or expansion of single-family residences where the addition of space to the exterior of the main structure is likely to adversely affect critical areas or is likely to obstruct the view of an adjacent development. (iii) When allowed, an equivalent area of shoreline buffer area shall be enhanced through planting of native vegetation, plus additional mitigation to be required as appropriate. The administrator shall require a planting plan to ensure this standard is implemented. 3.2 Critical Areas, Shoreline Buffers, and Ecological Protection According to JCC 18.25.270 (4) Regulations — Critical Areas and Shoreline Buffers: (c) Unless otherwise specified in this program, a buffer zone shall be established landward of all shorelines of the state to protect and maintain ecological functions and processes and to minimize risks to human health and safety. All buffers shall be maintained in a predominantly natural, undisturbed, undeveloped, and vegetated condition. Buffers shall not extend across lawfully established paved roads or hardened surfaces to include areas which are functionally isolated from the shoreline or critical area. (d) Building Setback. As established in Chapter 18.22 JCC, all new uses and developments, including preferred uses and uses exempt from shoreline permit requirements, shall be located landward of the standard buffer plus a 10 -foot -wide building setback unless otherwise specified in this program. (e) Standard Buffer. The standard buffer shall be measured landward in a horizontal direction perpendicular to the ordinary high-water mark (OHWM) of the shoreline water body, and is a three- dimensional space that includes the airspace above, as follows: (i) Marine Shores. A minimum buffer of 150 feet shall be maintained in all shoreline environments. (ii) Lake Shores. A minimum buffer of 100 feet shall be maintained in all shoreline environments. (iii) Stream/River Shores. A minimum buffer of 150 feet shall be maintained in all shoreline environments. MSA • McCullough Residence Expansion Mitigation • Planting Plan 3.3 Regulations — No Net Loss and Mitigation According to JCC 18.25.270 (2) — Regulations No Net Loss and Mitigation: (f) When compensatory mitigation measures are required, all of the following shall apply: (i) The quality and quantity of the replaced, enhanced, or substituted resources shall be the same or better than the affected resources; and (ii) The mitigation site and associated vegetative planting shall be nurtured and maintained such that healthy native plant communities can grow and mature over time; and (iii) The mitigation shall be informed by pertinent scientific and technical studies, including but not limited to the Shoreline Inventory and Characterization Report (Final — Revised November 2008), the Shoreline Restoration Plan (Final October 2008) and other background studies prepared in support of this program; and (iv) The mitigation shall replace the functions as quickly as possible following the impacts to ensure no net loss; and (v) The mitigation activity shall be monitored and maintained to ensure that it achieves its intended functions and values. The monitoring timeframes shall be consistent with JCC 18.22.350(3)(h). (vi) The county shall require the applicant/proponent to post a bond or provide other financial surety equal to the estimated cost of the mitigation in order to ensure the mitigation is carried out successfully. The bond/surety shall be refunded to the applicant/proponent upon completion of the mitigation activity and any required monitoring. 4. Mitigation Planting Plan 4.1 Planting Area The proposed plan will require —300 ftZ of planting area, which equals or exceeds the area of impact. The planting area is located within the marine shore buffer and should help to reduce stormwater discharge into Quilcene Bay. The planting plan will include Planting Area A (Figures 5A — 5B). Planting Area A is located along the southeast border of the project site and will reduce nutrients and pollutants from entering Quilcene Bay. Planting Area A will include ten shrubs and ten herbaceous plants. Shrubs will be installed with —5 -foot centers for spacing with herbs planted between (Figure 513). Plants to be installed for each area are shown in the following tables: Table 1. Plant Area A Quantity Botanical Name Common Name Stratum Size 3 Ribes sanguineum Red Flowering Currant Shrub 1 Gal 4 Rosa gymnocarpa Baldhip Rose Shrub 1 Gal MSA • MCCullough Residcncc Expansion Mitigation • Planting Plan Quantity Botanical Name Common Name Stratum Size 3 Symphoricarpus albus Common Snowberry Shrub 1 Gal 5 Polystichum munitum Sword Fern Herb 1 Gal 3 Mahonia aquifolium Tall Oregon Grape Herb 1 Gal 2 Athyrium felix femina Lady Fern Herb 1 Gal (*Plants will be selected from a regional native plant nursery) All invasive species will be identified and weeded prior to planting and soil will be amended where necessary. The plants will be installed by digging a one to two -foot hole, loosening the soil and root ball, and placing the plant in the ground. The hole must be deep enough to ensure that roots are straight, but not so deep as to bury plants too far above the root collar. Once the plant is in place the hole will be backfilled and tamped lightly. Mulch should be applied 3" deep at a radius of at least 12" around each plant, being careful not to touch stem of plant. Each plant shall be watered immediately after planting and mulching. 4.2 Performance Standards Performance standards are measurable criteria for determining if the goals and objectives of the mitigation project are being achieved. If the proposed benchmarks are not achieved by comparing the surveys to the mitigation goals, then contingency plans will need to be implemented. Performance standards are measurable criteria for determining if the goals and objectives of the mitigation project are being achieved. If the proposed benchmarks are not achieved by comparing the surveys to the mitigation goals, then contingency plans will need to be implemented. The goal of this mitigation plan is to maintain the critical area and to restore wildlife habitat. Performance standards will include: A. Survival rate: A 90% survival rate for installed plants and existing native plants will be the goal in mitigation areas. 90% survival will be expected in all monitoring years. B. Percent cover by native plants: Year one: at least 10-15% cover by installed and volunteer native plants. Year two: at least 15-25% cover by installed and volunteer native plants. Year three: at least 25- 35% cover by installed and volunteer native plants. Year four: at least 35-45% cover by installed and volunteer native plants. Year five: at least 45-55% cover by installed and volunteer native plants. C. Removal of non-native species in planted area: Less than 10% cover by non-native species. 4.3 Monitoring Plan An as -built drawing and report will be submitted to Jefferson County Department of Community Development as documentation of the implementation of the approved planting plan within one month of installation. The plan will include vegetation description, and photo documentation from established photo stations. Monitoring will take place over a period of five years at the end of the growing season (late August or early September) of each monitoring year. The performance standards will be monitored by measuring plots in zones within the planting area that will be established and mapped after planting occurs, on the as - built plan. There will be photo points for each plot and they will be referenced on the as -built plan. Photos MSA • MCCullotigh Residence Expansion Mitigation • Planting Plan will be taken at all points for all three years as visual documentation of the performance standards progress, or lack of. Collected data and photos will be compiled into a report for Jefferson County DCD. The report will address whether the performance standards are being met during each monitoring year and if the final end of monitoring period standards are going to be met. Monitoring results will determine whether or not contingency measures will be needed. Performance Standard # 1 (survival rate): Immediately after planting, all plants including planted and naturally established will be counted and documented. At the end of each growing season (late Aug -early Sept) plots will be visited and a count of surviving plants will be documented. The percent survival for the plots will be calculated by dividing the total number of plants after planting by the total number of surviving plants at the end of the season. Performance Standard # 2 (percent cover): The percent cover standard will be monitored by looking at each monitoring unit of the enhanced areas from above and estimating the area covered by the individual species. The percent cover within an area can be quantified as a total greater than 100% because plants (in tree, high/low shrub and herbaceous layers) overlap in cover. Performance Standard # 3 (removal of non-native species): The cover of non-native species should be maintained at less than 10%. The non-native coverage will be determined through the same process as determining the coverage of native plants in plots. Maintenance should occur at least two times during the growing season, one of which should be conducted before plants go to seed. The maintenance method will be hand removal, no herbicides. 4.4 Maintenance Maintenance shall occur at least twice during the growing season to ensure the survival of all native species within the mitigation area, including volunteer natives. Watering by hand or sprinkler may be necessary during year number one until the plants are established. Water requirements will depend on the timing of planting with the seasons and weather conditions. Once plants are established, extra watering may not be necessary. Hand weeding will be necessary around all plants that are being monitored for survival and coverage. It is desired that native species should repopulate the area naturally but should be considered weeds if the survival of plan plants is jeopardized, unless the species can potentially provide more value to the overall function of the buffer area in question. All non-native species shall be removed by hand at least twice during the growing season. If the 90% survival rate is not met by the end of any monitoring year, plants lost to mortality will be replaced to achieve the percent cover performance standard described above. Prior to replacement, an appropriate assessment will be performed to determine if the survival was affected by species/site selection, animal damage, or some other factor. Subsequent contingency actions must be designed to respond directly to the stressor(s) which are increasing mortality of planted native species. If a species is shown not to endure site conditions then another, more appropriate species will be selected. If excessive damage is observed, protective measures will be introduced. Monitoring years may be added if significant re -planting becomes necessary. 4.5 Contingency Plan If the 90% survival rate is not met by the end of any monitoring year, plants lost to mortality will be replaced to achieve the percent cover performance standard described above. Prior to replacement, an appropriate assessment will be performed to determine if the survival was affected by species/site selection, animal damage, or some other factor.

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) 1 75 (combined) Size of parcel acres An acre contains 43,560 square feet. Multiply the acreage by this figure Size of parcel in square feet 76230 sq/ft 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 str cture 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 CUTIFILL Calculate the total area to be cleared, graded, filled, excavated, and/or compacted for proposed development project Include in this calculation the area to be cleared for: Construction site for structures 656 sq/ft Drainfield, septic tank, etc. Well, utilities, etc. Driveway, parking, roads, etc. Lawn, landscaping, etc. Other compacted surface, etc. Total Land Disturbance sq/ft sq/ft sq/ft sq/ft sq/ft sq/ft Answer the following two questions related to conversion of native vegetation: Does the project convert % acres or more of native vegetation to lawn or landscaped areas? Circle: Yes No Does the project convert 2 % acres or more of native vegetation to pasture? Circle: Yes No Indicate Total Volumes of Proposed: Cut Fill (cu/yd) Impervious surface is a hard surface that either prevents or retards the entry of water into the soil mantle as under natural conditions prior to development. 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. stormwater talc worksheet — REV 10/20/2014 ,STORMWATER CALCULATIONS_ -IMPERVIOUS SURFACE NEW EXISTING Structures (all roof area) sq/ft I Structures (all roof area) 3,246 sq/ft Sidewalks Patios 656 sgtft Solid Decks (without infiltration below) Driveway, parking, roads, etc Other Total New TOTAL NEW + TOTAL EXISTING" 6,752 sglh sq/ft sq/ft Sidewalks Patios Solid Decks (without infiltration below) Driveway, parking, roads, etc Other '21850 Total Existing 6,096 sq/ft sq/ft sq/ft sgift sq/ft sq/ft sglft "This amount will be used to check total lot coverage The following questions will help determine whether the proposed project is considered development or redevelopment.

Yes 1 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.
