24 DRAFT City of Milton Shoreline Analysis Report Table 3. Function Summary of Surprise Lake Shoreline. Shoreline Processes and Functions Surprise Lake Alterations and Assessment of Functions Hydrologic Storing water and sediment LOW-MODERATE: The lake of course provides excellent water and sediment storage functions. However, the uplands surrounding the lake within shoreline jurisdiction have low water and sediment storage functions. Impervious surfaces and compact managed lawns interfere with infiltration of precipitation and rapidly send water downstream. Wetlands and other natural water and sediment storage features are generally lacking. Attenuating wave energy MODERATE: Wind and wave driven erosion is generally not a problem on the lake. However, bulkheading (primarily along the western shoreline) and other shoreline modifications have replaced native vegetation and natural woody debris as the features most likely to attenuate wave energy. Shoreline erosion is therefore not Removing excess nutrients and toxic compounds Recruitment of LWD and other organic material Vegetation known to be a serious problem on the lake. LOW-MODERATE: The lake is surrounded by intensively landscaped lakefront development. The upland shoreline areas are more often a source of nutrients and toxic compounds, via lawn treatment runoff (pesticides, fertilizers, herbicides), pet wastes, road and construction site runoff (hydrocarbons, metals, sediment), and septic systems. MODERATE: Residential development and other upland modifications restrict the ability of the lake to recruit significant LWD and organic material. Temperature regulation MODERATE: Lack of dense shoreline vegetation nearly eliminates potential for some shading of the shallowwater nearshore area. Vegetation is less effective at shading west- and south-facing shoreline areas due to afternoon sun from the southwest. Water quality improvement LOW-MODERATE: Residential areas surround the lake and in most cases are dominated by lawn and landscaping rather than dense buffers of native lakeside vegetation. These residential landscapes are sources of water quality contaminants such as fertilizers, herbicides and pesticides. In addition to the typical residential landscaping pollutants, runoff from surrounding urban areas carries hydrocarbons, metals, sediments, and other pollutants to the lake from roads, parking lots, and other developed areas. Attenuating wave energy MODERATE: In its pre-development condition, the lake was ringed with emergent wetlands and mature mixed-forest communities. Those communities are now almost entirely absent around the lakeshore, so vegetation provides limited wave attenuation function. As mentioned above, bulkheading and other shoreline modifications have replaced native vegetation and natural woody debris as the features in places (primarily the western shoreline) to reduce the effects of what limited wave energy there is on uplands. 16

25 The Watershed Company September 2010 Shoreline Processes and Functions Surprise Lake Alterations and Assessment of Functions Sediment removal and bank stabilization LWD and organic matter recruitment Habitat Physical space and conditions for life history LOW-MODERATE: Under natural conditions, there would be an ongoing, underlying rate of shoreline erosion, which would contribute to maintaining substrate conditions. This rate would be partially determined and moderated by the presence of shoreline vegetation whose root systems would tend to hold bank material in place. Instead, the lake shore now has little shoreline vegetation and a large proportion of it is armored. While this stabilizes the banks, it limits natural recruitment of lakebed materials. LOW-MODERATE: Again, the loss of natural, forested shoreline vegetation and its replacement primarily with lawn and other types of landscaping has nearly eliminated LWD and organic matter recruitment potential along the lake shore. Any trees or LWD that enter the lake are likely to be quickly removed out of concern for safety or to reduce the risk of property damage. The vegetated shoreline on the Camp Edgewood property is a notable exception. LOW-MODERATE: Under natural conditions, the lake bottom would gradually rise in a shallow wedge such that any incoming waves would roll up the bottom and onto the shore, losing energy. This reduced energy environment would be more hospitable to emergent vegetation, which further attenuates wave energy and provides a refuge for small fish and amphibians. Shallow nearshore areas in lakes typically provide rearing and foraging habitat for fish. Shoreline armoring, however, generally reduces this low-energy shallow-water environment, creating a deeper, more turbulent nearshore area that is less hospitable to small fish and amphibians, as well as to emergent vegetation. The deeper water may also allow larger fish predators to prey on small fish. The absence of dense shoreline vegetation is a limiting factor in terrestrial species (birds, mammals, amphibians) use of the shoreline, since cover, food, nesting sites, travel corridors, etc. are limited or largely absent. Food production and delivery LOW-MODERATE: Food production from the uplands is limited by the lack of native seed- and fruit-bearing vegetation. This may be made up for, in part, by fruit trees and other non-native vegetation in yards which supplies some food for wildlife. Not only does native upland vegetation provide food directly for terrestrial wildlife, but it is a source of insects and other organic matter that drop into the water to provide food for fish and other aquatic life. The historical emergent wetland areas that are now reduced or absent also provided productive foraging areas for small mammals, wading birds and waterfowl. Summary Accounting for the existing hydrologic, vegetative, and habitat conditions within the shoreline surrounding Surprise Lake, the overall shoreline ecological function is considered LOW-MODERATE. 17

28 DRAFT City of Milton Shoreline Analysis Report Table 4. Function Summary of Hylebos Creek. Shoreline Processes and Functions Hydrologic Storage of water and sediment Transport of water and sediment Hylebos Creek Alterations and Assessment of Functions LOW/MODERATE: Adjoining floodplain and riparian wetland areas contribute to this creek s ability to store water and sediment during high flow events. However, downstream sections of the stream are quite narrow and constrained by development. MODERATE: The stream has been channelized through portions of this reach. Paired with increased development in the basin, the flow regime and the sediment transport capacity have likely been altered. This system may be less sensitive to such alterations, given the large areas of adjacent wetlands. Attenuating flow energy MODERATE: As mentioned above, some sections of broad floodplain remain in this reach. These are effective at attenuating streamflow energy during flood events. However, the recruitment of woody debris, especially LWD, is impaired due to clearing and the small size of the streambank trees remaining. To its benefit, the basin includes associated wetland areas which serve to dampen and moderate stream flow fluctuations. Still, the decrease in channel roughness brought on by a reduction in accumulated woody debris and bank vegetation has reduced the stream channel s ability to absorb and dissipate stream flow energy. Developing pools, riffles, and gravel bars Removing excess nutrients and toxic compounds Recruitment and transport of LWD and other organic material LOW/MODERATE: Reduction in roughness elements, via channelization and removal of LWD has resulted in a simpler channel form which is less conducive to the formation and maintenance of the basic habitat elements, including pools, riffles, and gravel point bars. MODERATE: Remaining broad floodplain areas provide a competent biofiltration function. However, upland shoreline areas and developed, former floodplain areas now functioning essentially as upland are more often a source of nutrients and toxic compounds than a sink, due to impervious surface runoff (hydrocarbons, metals). LOW: Streambank forest vegetation, particularly large trees, has been reduced, reducing the recruitment of large logs and some other vegetative material as well. Remaining trees along the creek are typically small in size, so opportunities for recruiting large wood are reduced. Furthermore, channel migration has been curtailed by channelization. Laterally migrating channels recruit the forest materials in their paths and also recruit and recycle riverbank gravels laid down along previous channel alignments. Vegetation Temperature regulation LOW/MODERATE: Well-vegetated banks and buffers improve shading conditions, in turn benefiting both temperature and dissolved oxygen. Low density and small size of shoreline vegetation greatly reduces the level of shading afforded the creek. However, smaller vegetation is needed to provide shade to a narrower creek as opposed to a wider river. 20

29 The Watershed Company September 2010 Shoreline Processes and Functions Hylebos Creek Alterations and Assessment of Functions Water quality improvement MODERATE: Where wide floodplain areas remain and are densely vegetated with willows, grasses, emergent vegetation, and other riparian vegetation types, an effective level of biofiltration can still occur. However, urbanizing areas in the basin are dominated by roads, parking areas and landscaping, and lack densely vegetated buffers of sufficient width. These urban areas are sources, rather than sinks, of water quality contaminants such as fertilizers, herbicides, pesticides, hydrocarbons, metals, and eroded soils. Slowing riverbank erosion; bank stabilization MODERATE: The dense grasses and shrubby vegetation that line much of Hylebos Creek are fairly effective at stabilizing soils and slowing the rate of erosion. However, the function of slowing the rate of bank erosion formerly provided by bank vegetation has now been taken over by artificial armoring in some areas, such as at the road crossings. Prior to settlement and clearing, the creek would have been lined with mature, mixed-forest communities. Attenuation of flow energy LOW/MODERATE: (As stated above), the decrease in channel roughness due to a reduction in accumulated woody debris, channel straightening, and reduction in bank vegetation has reduced the channel s ability to absorb and dissipate stream flow energy. Sediment removal MODERATE: As stated above, remaining densely vegetated floodplain areas are effective filters for the filtering Provision of LWD and organic matter Hyporheic Removing excess nutrients and toxic compounds Water storage and maintenance of base flows and retention of fine sediments. LOW: Streambank vegetation now consists primarily of grasses along much of this reach, and includes only smaller tree sizes in the remaining areas, so there is little opportunity for the recruitment of LWD. MODERATE: The soils in this portion of the stream are largely fine-grained and not as conducive to hyporheic flow as a coarser substrate would be, limiting the natural potential for hyporheic removal of excess nutrients and toxic compounds. MODERATE: As above, the existing soils are not likely conducive to significant hyporheic flow, limiting the potential for water storage and base-flow maintenance. Support of vegetation MODERATE: Though hyporheic flow is limited, the vegetation supported by such flow has been altered significantly in much of this reach. Habitat Physical space and LOW/MODERATE: Habitat in and along Hylebos Creek has been reduced in quality, quantity, and complexity conditions for life history compared to its original condition. The vegetative community is now much sparser and with a much lower level of accumulated downed wood and snags, resulting in fewer places for various wildlife species to find cover or suitable nesting and rearing sites. The diminishment of dense shoreline vegetation is a limiting factor for 21

30 DRAFT City of Milton Shoreline Analysis Report Shoreline Processes and Functions Hylebos Creek Alterations and Assessment of Functions terrestrial species (birds, mammals, amphibians) use of the shoreline, since cover, food, nesting sites, travel corridors, etc. are absent. Within the channel itself, less wood overall similarly results in less available protective cover, and diminishes the creation of pool/riffle sequences as well. A reduction in side channels backwaters and sinuosity has reduced the amount of valuable edge habitat available, and further reduced overall complexity. Food production and MODERATE: Food production from developed floodplain and upland areas is limited by a reduction in native delivery seed- and fruit-bearing vegetation. Not only does such vegetation provide food directly for terrestrial wildlife, but it is a source of insects and other organic matter that drop into the water and provide food, either directly or indirectly, for fish and other aquatic life. The historic, but now reduced, emergent wetland areas also provided productive foraging areas for juvenile fish, small mammals, wading birds, and waterfowl. Summary Accounting for the existing hydrologic, vegetative, hyporheic, and habitat conditions within Hylebos Creek, the overall shoreline ecological function is considered MODERATE. 22

Shoreline Waterbody Surprise Lake Single-Family Residential Zoning Multi Family Residential Zoning Hylebos Creek Single-Family Residential Zoning Manufacturing East of I-5 Likely changes in land use and implications for shoreline management. Likely Changes in Land Use This area, located along the west side of the lake, is currently zoned Residential Single Family District, which allows up to 5.45 dwelling units per acre. Most of these parcels are built out and are not likely to change use. Approximately 3 vacant lots exist around the lakeshore, but these may be owned by adjacent properties or are owned and used as community access lots which are unlikely to develop in the near future. Some redevelopment of existing housing stock may occur. This area, located along the north and east side of the lake, is currently zoned Residential Multi- Family District, which allows between 4 and 12 dwelling units per acre. This area includes a mixture of single-family residences, the Surprise Lake Village Apartments and Camp Edgewood. All of these parcels are built out and are not likely to change use. However, some redevelopment of existing structures may occur. This area is zoned Single Family Residential, which allows up to 5.45 dwelling units per acre. The area is almost entirely developed with single-family residences, although not at the maximum densities allowed. New development and/or subdivision of property is possible in the future. However, the area of shoreline jurisdiction is entirely contained within the identified associated wetland. Thus, substantial new development is unlikely to occur. Redevelopment of existing structures is the more likely scenario but likely would occur outside of shoreline jurisdiction. This area is zoned Light Manufacturing and includes the Implications for Shoreline Management Shoreline Residential appears to be the most appropriate environment designation for this segment.
