4.0 OPPORTUNITIES AND CONSTRAINTS ANALYSIS 115

4.0 OPPORTUNITIES AND CONSTRAINTS ANALYSIS

The purpose of this comprehensive analysis of opportunities and constraints for the Sly Park Recreation Area is to give a clear picture of how the site encourages or limits recreation development. Each topic analyzed within this section is based on existing conditions and issues as described in Section 3. Opportunities and constraints are considered for the following resources:

Climate

Geology

Hydrology

Biological resources

Forest resources

Visual resources

Cultural resources

Traffic and circulation

Noise

Land uses and zoning

Public utilities

Recreation

Opportunities are those site characteristics that may encourage certain types of use or development. For example, a site that provides scenic vistas would be a desirable destination for both picnickers and hikers. Constraints are those characteristics that might limit or restrict use. Examples include steep slopes or sensitive wildlife habitat.

It is the general intent of this Master Plan, as reflected in Section 2, Goals and Objectives, to respond as closely as possible to identified

opportunities and constraints while minimizing environmental impacts.

There are some inherent conflicts between opportunities and constraints. For example, creeks, which are sensitive ecosystems, are also desirable locations for trails and other recreational pursuits. These potential conflicts have been evaluated with the intent of balancing recreational opportunities with the need to protect valuable resources.

4.1 CLIMATE Opportunities

Located between 3,400 and 4,000 feet in elevation, SPRA provides a respite from the heat of the Central Valley all summer long and into the fall. Seasonal variations also provide added beauty to the area. Many visitors travel to SPRA expressly to see fall colors on black oaks and big leaf maples as well as spring wildflowers and blooming Pacific dogwood, all of which are especially appealing and not commonly found in lower elevations or urban areas. This aspect could be a marketing tool to attract off-season visitation.

Occasional periods of deeper snow provide the opportunity to learn snowshoeing or cross-country skiing. Winter camping is also possible at these times. All-weather, convenience camping units such as cabins and yurts could also encourage additional off-season use by people who enjoy the views and relative solitude of the winter landscape but are not interested in tent camping in winter conditions.

4.0



Constraints

Cold weather, rain, and snow can be a major detraction to many potential campers, especially when combined with a lack of adequate shelter. In some years, SPRA’s location in the Sierra Nevada limits year-round uses due to snow and adverse travel conditions from late October through March.

4.2 GEOLOGY The two primary geologic considerations for recreational uses at SPRA are topography and soils. The nature of the soils and underlying rocks, coupled with the topography at SPRA, generate both opportunities and substantial constraints to the types of buildings and facilities that can reasonably be constructed.

4.2.1 TOPOGRAPHY Opportunities

Flatter areas of SPRA, those with slopes of 10 percent or less, are more desirable for many recreational uses, including structures, trail staging areas, trails, day use areas, and campgrounds (Figure 4-1).

Where slopes are 5 percent or less, campsites can be established at a 2 percent slope with relatively little grading (cuts and fills of 19 inches or less) needed to accommodate an RV or a vehicle/trailer combination as well as a “patio” area with a picnic table, fire ring/grill, and sitting room. Such minimal changes in grade can easily be retained with natural materials such as logs and boulders.

Areas with slopes that exceed 5 percent may still provide opportunities to offer other types of camping facilities, such as convenience units (platforms, cabins, or yurts) constructed on piers.

Areas with slopes ranging between 10 and 15 percent can still be utilized for handicap

accessible and less strenuous trails when designed with proper alignments.

Constraints

The majority of land within SPRA exceeds slopes of 15 percent. Land with less severe slopes has already been developed extensively for recreation uses. Recreation uses and facilities planned for areas exceeding slopes of 15 percent will generally require the use of retaining walls to provide reasonably flat, usable spaces. This not only increases a project’s cost but poses accessibility and potential maintenance issues as well.

4.2.2 SOILS Soil erosion potential, permeability, and construction suitability are generally constraining factors with respect to the continued use of SPRA and future facility development.

Constraints

All of the soils at SPRA are moderately to highly erosive (Figure 3-4). This erosive quality can be observed along the entire shoreline, on the trails, and in the campgrounds. Erosion prevention and repair on trails and unsurfaced roads will require careful planning and regular maintenance.

Most of the slopes around SPRA exhibit some degree of soil creep where subsoil is exposed by cuts. On banks or steep slopes where erosion is unchecked, the potential for landslides is a safety concern for park visitors. The north shore is currently showing impacts from wind-generated wave action at high-water levels. Both wind-generated wave action and motorized boat wake action have contributed to bank instability along the south shore. Along the greater percentage of the south shore, these bank cuts range from one to eight feet in height. These cuts not only pose a significant hazard to recreational trail users but



also make the shoreline more prone to further erosion due to loss of stabilizing vegetation.

Continued overuse of existing trails and campgrounds may worsen soil erosion along the west and north shores. Undefined campsites and parking areas result in soil compaction, the eventual loss of soil stabilizing vegetation, and increased runoff.

New facilities and expanded recreational uses will be constrained by the suitability of the land to support them. Currently, the campgrounds use self-contained vault privies for restroom facilities. The Geotechnical Analysis conducted for this Master Plan (Appendix F of the SPRA Master Plan EIR) indicates that soils in the park have a moderate capacity for septic system development. The study also shows the presence of Valley Springs and Mehrten formations, often containing hard rock that may require blasting to excavate for new construction. These formations may also contain dispersive clays or clays that have a significant shrink-swell capability.

All of these constraints can be managed by site-specific planning for each new facility. This can be achieved by conducting focused studies to identify site specific conditions, such as slope stability and expansive clays, as well as potential impacts of improvements. Focused studies should also provide specific recommendations for effective mitigation measures.

Specific studies should examine soil suitability for each facility planning to use on-site wastewater disposal systems. Structures requiring any earthwork should be evaluated for erosion potential and the need for further geotechnical analysis.

All grading activities are subject to local regulations, including implementation of Best Management Practices to mitigate potential construction-related impacts.

Bioremediation strategies may be used to stabilize shoreline erosion and simultaneously reduce hazards, enhance habitat, and reduce impacts on natural and archaeological resources. Shoreline stabilization would also help protect the lake’s high water quality.

4.3 HYDROLOGY Opportunities

Jenkinson Lake has been used for water-related recreation activities for many years and continues to have very high water quality (EID, 2004). Indeed, the lake’s water quality is one of the reasons it provides excellent opportunities for fishing, motor boating, waterskiing, canoeing, kayaking, paddle-boating, and swimming.

SPRA’s easily accessible location and the lake’s high water quality suggest that the park would be an excellent location for a watershed/water quality education program. The opportunity also exists to provide environmental interpretation where trails cross creeks and drainages. Creek locations are illustrated on Figure 3-6.

Constraints

Jenkinson Lake provides a substantial portion of west El Dorado County’s drinking and irrigation water. The lake’s water quality is an important issue that must be considered before any new activities are allowed within the park. The lake water is required to meet certain standards set forth by the California Department of Health Services (DHS), Central Valley Regional Water Quality Control Board (CVRWQCB), and the U.S. Environmental Protection Agency (EPA).

A minimum setback of 50 feet from the ordinary high water mark of creeks should be established and strictly adhered to when developing or rehabilitating park facilities. Creeks are environmentally sensitive areas that can be degraded through inappropriate or extensive human use.

Lake levels generally draw down throughout the summer and fall and may result in lake access issues from as early as mid-July until the following spring. Amenities and equipment

planned for use along the shore be adaptable to these constantly changing lake levels. For example, floating docks should be used to minimize manpower needed to make frequent adjustments.

The FEMA 100-year flood zone corresponds closely with the maximum water level of the lake. All capital improvements should be planned outside of this zone.

In order to protect water quality, the park’s recreational uses must be managed to limit increases in erosion and sedimentation, coliform counts (total and fecal), and petroleum hydrocarbons from fuels.

Erosion is a leading non-point pollutant source for surface waters nationwide because eroded soil entering lakes and streams can carry pollutants with it and impair aquatic habitat. Excessive camping and foot traffic at SPRA have already resulted in highly compacted areas in many of the campgrounds. These areas have a corresponding decrease in storm water infiltration and increased potential for surface runoff and erosion. These problem areas need to be addressed, and constraints implemented to prevent the future recurrence of the problem.

The potential degradation of water quality and habitat due to erosion also constrains SPRA trail and road design and location. If trails are to cross streams, bridges are needed to prevent unstable banks and excess erosion. Roads and shore trails must be properly designed to prevent the concentration runoff and formation of rills and gullies on slopes leading to the lake.

Erosion as a pollutant source is being addressed by the EPA through their National Pollutant Discharge Elimination System (NPDES) program. Any future SPRA construction activities may be required to obtain an NPDES General Construction Storm Water Permit to



ensure containment and minimization of construction related erosion.

Jenkinson Lake has very low levels of fecal coliform and other related contaminants. Most of these contaminants that do exist in the lake occur naturally due to the presence of wildlife and are not a threat to water quality for drinking or recreation (EID, 2004). In order to prevent increased levels of these contaminants, visitors are not allowed to let dogs and diaper-wearing infants into the lake.

Petroleum hydrocarbons can also contribute to nuisance odors and decreased water quality. Motorboats need to be properly maintained to reduce the risk of spills and leaks. The design of new road and parking facilities needs to incorporate measures to prevent the discharge of storm water runoff directly to the lake or creeks.

4.4 BIOLOGICAL RESOURCES

Opportunities

There are opportunities for specific habitat enhancement in the Sierra Day Use Area, the Hazel Creek corridor, and in the meadow near the Hazel Creek Day Use Area. These sites would benefit from limitations on human access and replanting of native species to facilitate habitat regeneration.

SPRA also contains appropriate habitat throughout many areas of the park for special status species, especially a variety of raptors (see Appendix E of the SPRA Master Plan EIR). Opportunities exist to protect, enhance, and expand this habitat and potentially the populations of these sensitive species through management practices and focused revegetation efforts.

Star thistle, a highly invasive non-native species, is present in the western portion of the park,

primarily around the old quarry below the dams. Eradication of this and other invasive non-native plants would enhance habitat value for native species.

Constraints

SPRA’s sensitive habitats are the vegetation communities that are of specific concern in California. These include areas that provide habitat for special status species as described in Appendix E of the SPRA Master Plan EIR, streams that are regulated by CDFG under section 1603 of the California Fish and Game Code, and mesic areas that potentially qualify as wetlands under USACE jurisdiction pursuant to section 404 of the Clean Water Act. Areas mapped as Montane Riparian and Drainages (Figure 3-10) are subject to regulation under the CDFG code. Any activities within SPRA that result in streambed alteration will require a Streambed Alteration Agreement with CDFG.

If new areas of development or forest management activities are planned, surveys for special status species as identified in Appendix E of the SPRA Master Plan EIR should be conducted. Impacts to special status species should be avoided to the extent practicable and mitigated where impacts cannot be avoided. Depending on survey results, coordination with resource agencies may be needed to identify appropriate avoidance and mitigation strategies.

4.5 FOREST RESOURCES Opportunities

The implementation of various forest management practices, as discussed in Appendix B, could provide many benefits and opportunities to SPRA. These practices could benefit forest health, improve aesthetic views through the forest, and reduce fuel loads and the associated danger of wildfires.



Specific forest management practices may also be employed to enhance habitat value for some wildlife species. For example, maintenance of late seral stage forest south of the lake would benefit spotted owl and northern goshawk. Forest management practices may also be used north of the lake to minimize invasion of brush and maintain open habitat for native grasses and forbs, including special status plant species. Forest management to prevent suppression of oaks would provide greater habitat diversity north of the lake.

Some forest stands at SPRA are over stocked and growing, on the average, about 10 rings per inch (see Appendix B). There is potential to manage these stands to release co-dominant and dominant conifer and oaks for promotion of growth. Growth rates are higher in portions of the park where soils are deep and trees are not overstocked.

Constraints

SPRA forest management practices need to be scheduled to limit their intrusion on the quality of visitors’ experience. This will be increasingly important as new facilities are provided and visitor use expands throughout the year. For example, timber harvesting should be limited from the last weekend in May through the first weekend in September to avoid adversely affecting visitors during the prime recreation season.

Another scheduling concern is the need to adjust the timing for under-story burning to periods of high-fuel moisture and cooler air temperatures. This practice will reduce the mortality rate of young conifers and limit the early succession of species such as oaks. The frequency of burning also needs to be evaluated in areas of the park where California black oak regeneration is to be encouraged. Repeated burning to control brush in the fall is eliminating regeneration of California

black oak. The loss of mature black oak due to natural mortality and the absence of regeneration will lead to a continuing decline of the species in the park.

Forest management treatments implemented from February through June have the potential to create insect brood material if woody debris is not properly disposed of.

Forest management also includes aesthetic constraints. While the SPRA forest is not intended to be managed as a commercial enterprise, trees will periodically need to be logged and sold for purposes of forest health, public safety, and the enhancement of recreation and biological resources. Any proposed harvesting will need to be carefully planned and implemented to ensure that visual resources are not negatively impacted. When trees are removed, stumps should be flush cut or ground down where appropriate to improve the visual appearance of an area after harvest.

Other constraints associated with forest management may include:

In lieu of hauling logs through the park, temporary use permits from USFS and Sierra Pacific Industries may be required to use off-site roads.

Operations need to be limited to reasonable periods to avoid noise impacts.

Directional felling will be necessary near facilities and roads.

Soil protection and dust abatement during harvesting activities may be required to protect water quality.

4.6 VISUAL RESOURCES Opportunities

The visual resources at SPRA include the lake, the forest, and the topographic variation. The



forest and site topography can also be utilized in conjunction with sensitive and judicious site planning to hide or minimize the visual impact of renovated or newly constructed facilities. For example, by taking advantage of screening ridges most new campground areas can be sited so they are minimally visible from Sly Park Road and to neighboring residents. Careful siting of structures and roads among existing trees within each of the campground areas can minimize the visual impact on other areas in the park, including the lake and the south shore trails.

Although the majority of developable sites around the lake are already being utilized, there are still opportunities to maximize views of the natural environment in siting new facilities and redeveloping existing facilities, and to improve the aesthetics of those facilities and the area around them.

Many vista points along the lakeshore and ridgelines provide spectacular views that can also serve as trail destinations.

Constraints

Careful attention needs to be given to site planning for the renovation of existing facilities and proposed new facilities in all locations around the lake to minimize visual impacts. Implementing projects as recommended in Section 6, Design Standards and Guidelines, will be important to creating a rustic, natural look consistent with the existing natural environment. Consideration should be given to developing a design review committee to review proposed improvements for compliance with the guidelines.

4.7 CULTURAL RESOURCES Opportunities

There are numerous opportunities at SPRA for the interpretation of cultural resources.

Interpretive themes could include Native American culture, mining, pioneer settlement, early logging, transportation, and emigration through the region, as well as early water use, impoundment, and conveyance. The SPRA trail system, campgrounds, and day use areas afford many suitable locations for the placement of interpretive displays and signage. Programs such as walks and lectures could also be led by volunteers or park staff to further educate visitors.

Constraints

Recreation facility development and use must be coordinated with the protection of cultural resources. Where appropriate, protective measures should to be designed to prevent damage to sites where cultural resources are located, without revealing the presence of these resources. If protection cannot be provided, data recovery excavations of the resources should be considered to prevent further loss of the data from the sites. Any plans for these resources should be developed in consultation with appropriate Native American groups and individuals.

4.8 TRAFFIC AND CIRCULATION

Opportunities

There is sufficient area at the SPRA main entrance to allow reconfiguration of various components to reduce congestion and potentially reduce stacking on Sly Park Road.

On Mormon Emigrant Trail, there is an opportunity to consolidate the two entrances for the group camp sites and the Retreat House Complex into a single entrance. The new entrance could include a staffed booth to check guests in and provide information. This arrangement could help limit unauthorized visitation.



Safety and circulation throughout the park could be improved by widening portions of Lake Drive and the campground access roads to more uniform widths.

Realignment of some of the campground roads could result in a more efficient layout and use of existing campgrounds.

There are numerous opportunities to improve parking by designating and delineating parking spaces in campgrounds and day use areas. Depending on the location and current use of a particular area, there may be some opportunities to develop additional parking without displacing other uses. The potential development of the Sugarloaf Fine Arts Camp (see Section 5.3.2) could result in the availability of additional day use parking when camp is not in session.

The off-site dirt roads on Sierra Pacific Industries property could provide interim access to SPRA in the event of an emergency. Ensuring that these roads are passable could be beneficial to both parties in the event of a wildfire.

Constraints

The current configuration of the main SPRA entrance is a constraint to moving visitors in and out of the park quickly, safely, and efficiently.

Lack of parking and traffic congestion are constraints that combine with staff shortages and environmental sensitivity to ultimately limit recreation use at SPRA. This is especially true at day use areas where parking spaces are not clearly defined and may turn over several times in a day. Staff has no way to direct day users to specific parking places or to know when all day use spaces are full. Staff is not available to continually patrol parking areas to make sure the number of cars does not exceed the capacity of the parking area. Soil compaction and damage to

vegetation can result when cars are parked outside of the parking area.

While sections of Lake Drive would benefit from road improvements, in certain locations such work may be constrained by topography, natural resources, and other improvements. Any planned improvements to Lake Drive should be scheduled for the slowest parts of the year to avoid disruption to park visitors.

The potential for forest fire is extremely high in the vicinity of SPRA. The nature of recreation uses at the park also carries the potential for medical accidents or emergencies. Because Lake Drive is too narrow to accommodate two-way traffic in many areas, in the event of a fire or other emergency it would be difficult to impossible to get emergency vehicles into the east portions of SPRA while trying to evacuate park visitors. An emergency evacuation plan that includes coordination with adjacent property owners is needed. A simple, concise map showing evacuation routes and procedures should be provided to visitors when they register or pay at the gate.

4.9 NOISE Opportunities

The noise of large groups is sometimes bothersome to other campers because of an expectation for peace and quiet. Increasing separation between campsites and between campgrounds, particularly group campgrounds, may potentially reduce the intensity of noise generated. Increasing ranger patrols may also help to limit this problem.

Constraints

The location and operation of any new facility needs to consider the impact of noise on other park visitors and local neighbors, including rules for quiet time and the use of amplified sound.



4.10 LAND USE AND ZONING Opportunities

The majority of land contiguous to SPRA to the north, east, and south is owned either by the USFS or Sierra Pacific Industries. The USFS lands are zoned RA-80 and managed as part of the Eldorado National Forest. The USFS has typically been supportive of existing uses at SPRA and has worked to coordinate trail development.

Sierra Pacific Industries lands are zoned TPZ and are restricted to timber harvesting and ancillary uses. Other uses permitted by right include many of those currently occurring within SPRA, including watershed and wildlife management, and non-commercial recreation uses such as fishing, day use activities (picnicking, riding, hiking), and camping.

Constraints

In order to implement the Master Plan, it must be consistent with the adopted El Dorado County General Plan. The current General Plan land use designation for SPRA is Natural Resource (NR). This designation allows limited recreation uses. If proposed improvements in this Master Plan are found to be inconsistent with the NR designation, a General Plan Amendment will be required to achieve consistency between the two plans.

The renovation of existing facilities and development of any new facilities may require special use permits or variances from the El Dorado County Planning Department.

4.11 PUBLIC SERVICES

4.11.1 WATER Opportunities

Potable water is available in all campgrounds within SPRA and at the Retreat House Complex.

While the existing water service line along the west and north shore poses a major constraint on any additional development in those areas, that limitation will soon be removed with the anticipated water service upgrade. An increased water supply will provide the opportunity to develop shower and laundry facilities somewhere along the new water line which will end at Hazel Camp.

EID has determined that water pressure may be sufficient to also supply water to Scout Hill. If not, water service could be brought to the site from the residential developments on the west and north.

Constraints

There are no plans to upgrade or provide any new water services along the Mormon Emigrant Trail. Existing facilities are limited by the current service. The existing system should be evaluated to determine if showers could be provided at the group campground.

Without a water line to this area, the proposed Sugarloaf Fine Arts Camp would have to drill an acceptable well or transport water in, as well as provide sufficient storage capacity to meet the fire suppression and potable water requirements.

4.11.2 ELECTRICAL Opportunities

While electrical service is very limited at SPRA, the proposed Sugarloaf Fine Arts Camp may be able to secure electrical service from nearby PG&E transmission lines. It may also be possible to add another transformer to the existing infrastructure on the north shore near Jenkinson Camp to provide electricity for some limited new uses, such as a laundry facility or cabins.



Constraints

With one minor exception, electricity is only available at park headquarters, the Marina, and the Retreat House Complex. All services are currently at maximum capacity.

Electrical services are expensive, requiring an upfront capital outlay. If conduit cannot be installed concurrently with proposed water line improvements, costs to underground future electrical infrastructure may be prohibitive.

4.11.3 WASTEWATER

TREATMENT Opportunities

“Green” alternatives to traditional septic systems, including composting toilet systems such as those utilized by national and state parks, should be considered to reduce the overall cost associated with septic waste.

Grey-water disposal systems should also be considered for proposed showers and laundry facilities to avoid costly disposal fees.

Constraints

There is no wastewater treatment plant at SPRA; the Retreat House Complex and park headquarters utilize septic systems. Toilets at the campgrounds and day use areas are waterless units that must be pumped frequently.

Alternative approaches to wastewater treatment, as well as any new traditional septic systems, will require approval from the El Dorado County Health Department.

4.11.4 TELEPHONE SERVICE Opportunities

The water tower at the Retreat House Complex, or some other location within SPRA, may be suitable as a cellular relay site, provided the visual impact could be minimized and such a

facility was determined to be technically and financially feasible by a cellular service provider. Revenue generated from lease contracts could be utilized to develop or redevelop facilities at SPRA. An accessible, reliable phone system would also enhance public safety.

Constraints

Land-based phone service is essentially non-existent within the park with the exception of park headquarters. Cellular phone reception is spotty at best within the park, making it undependable.

4.12 RECREATION

4.12.1 BOATING Opportunities

There is an eight-year waiting list for the Marina’s 78 rentable boat slips. The Marina is one of SPRA’s most consistently utilized features and will most likely continue to be a highly sought after recreation amenity.

On weekends during the summer months there is enough demand for rental boats to occupy all boats available at the Stonebraker boat launch rental facility, including motorized aluminum fishing boats, canoes, kayaks and paddle boats. More rental boats could be added to increase revenues.

The Stonebraker boat launch is located within the 5 MPH zone. This provides non-experienced boaters with a greater level of safety than is found in the remainder of the lake where higher speeds are allowed.

Constraints

The primary constraint for the Marina is the limited number of boat slips allowed. When the Marina parking area was last expanded with grants from CBW, stipulations were made with respect to the maximum number of slips allowed



due to the presence of foraging bald eagles and osprey.

Due their location on the lake, the Marina docks often sustain substantial damage when they are twisted by high winds. Unfortunately, the type of docks used cannot be anchored, so, until they are replaced with a different type of system, they will be subject to wind damage.

Although access to the Marina docks is restricted by a locked gate, swimmers often circumvent the gate in order to use them for diving and jumping.

There is tremendous demand for lake access at the Marina from boaters who don’t rent slips, but the current boat launch capacity (4 lanes) exceeds the existing Marina parking capacity. CBW has awarded a grant to EID that would partially fund expansion of the Marina parking facility, but implementation of this expansion is contingent on CEQA compliance, securing additional funding, and approval by the EID Board.

The Stonebraker boat rental facility is located in the eastern area of the park away from the larger, more popular campgrounds. It is impossible to see from the road because it is situated at the bottom of a steep embankment. Access requires descending a narrow concrete stairway to the water’s edge. Alternate locations for docks have been considered, but the long flat shorelines at other sites, such as Chimney or Hazel Creek, make access difficult once water levels start receding in early July.

4.12.2 CAMPGROUNDS Analysis of SPRA campgrounds reveals many common opportunities and constraints as well as some specific to each campground.

General Opportunities

The primary issues with all of the existing campgrounds are campsite densities, lack of campsite definition, and, in some cases, campsites located too close to sensitive resources or steep slopes. In combination, these factors are contributing significantly to environmental degradation, including over compaction of soils and destruction of vegetation. These impacts can precipitate erosion and damage water quality and forest health.

These factors also contribute significantly to the occurrence of user conflicts. Reconfiguring each campground to reduce campsite densities to a more moderate level and siting campsites appropriately according to the existing slope and type of campsite would help to reduce all of these problems.

In general, the same basic amenities are found at each campsite. Providing additional amenities, such as lantern poles and prep tables, could justify moderate fee increases if these amenities could be secured against theft and vandalism

SPRA visitation might be expanded by providing convenience camping units (such as cabins and yurts) to attract people already drawn to region by tourist attractions such as Apple Hill and the numerous wine tasting areas. Sites that would be well-suited to test out the popularity and demand for convenience units should have good road access and views of the lake, to enhance the premium camping experience.

Convenience camping units provide a more financially viable option for people who do not prefer traditional camping, but cannot afford more expensive bed and breakfast or resort facilities and dining options. Additionally, convenience units could increase camping during the shoulders of the peak season and potentially through the winter, although the demand for



winter camping would probably be very limited. The Market and Economic Analysis in Appendix A discusses these opportunities in more detail.

General Constraints

A substantial change in the overall camping experience from traditional camping to convenience camping may not be well received by people who have been camping at SPRA for many years or generations.

Pinecone Camp The proximity of the day use area to the

campground requires the clear delineation of day use parking from that of campers.

Jenkinson Camp Jenkinson is the only existing campground

with reasonable expansion potential uphill from existing campsites; however, the gradient of the area makes it suitable for convenience units only. Another potential expansion area for convenience units is located east of the campground along an existing unpaved access road.

Expanding the campground would require construction of new roads and, at minimum, expansion of the water line to provide potable water for new sites and toilets. Some tree removal may be necessary for road construction. Although convenience units are relatively small and can be flexibly sited, some additional tree removal may be needed depending on tree density in this area.

Sierra Camp The location and orientation of Sierra Camp

affords some of the best views of the entire lake.

Because of its size, this campground offers a great opportunity to renovate campsites to benefit both the environment and quality of the visitor experience. The most degraded campsites on the west side of the campground nearest the lake are excellent

candidates for reconfiguration and for revegetation to improve site conditions.

Day use and camper parking need to be clearly delineated and identified to reduce conflicts.

Stonebraker Camp The smallest of all the campgrounds,

Stonebraker can function as a small group/extended family campground.

Hilltop Camp Hilltop Camp is best suited for traditional

campsites but needs better definition of individual campsite boundaries.

This area would benefit from revegetation once camper impacts are limited to defined campsites.

The entrance to this campground is very confusing and should be signed or realigned if feasible.

Chimney Camp Parallel parking could be provided at

Chimney Camp by constructing short retaining walls on the up-hill side in order to define parking spaces for campsites.

Hazel Creek Camp The tree canopy at Hazel Creek Camp and its

proximity to the creek makes it peaceful and quiet, which is especially appealing to some campers.

This campground should be renovated to accommodate traditional campsites that are more dispersed and defined. Moving campsites away from the creek would provide better protection for wildlife and habitat and provide an excellent restoration opportunity.

The proximity of the creek to the campground may pose some environmental and permitting constraints for redevelopment.



Dogwood Camp The tendency for campers to be disorderly at

Dogwood Camp may be exacerbated by the fact that this campground is so far from park headquarters.

The majority of this campground appears to be suitable for tandem spurs for RVs and vehicle/trailer rigs.

This campground is small and grades will require a linear configuration of tandem spurs.

Scout Hill Scout Hill is already being used on a limited

basis by Boy Scout troops for Camporees. The site is located on a gently rolling ridge providing enough flat area to accommodate various types of camping facilities, including larger structures such as a mess hall or mess tent.

Horizontal distances ranging from 1,600 feet to 2,400 feet separate this ridge from residences to the west. There is a substantially forested ridge between these two areas that provides a visual and sound buffer.

Scout Hill is located away from existing campgrounds, reducing the potential impact of Scout Hill activities on other campers.

As the forest in and around this area has been thinned to reduce fire danger over the years, there is substantial space between trees in which to locate structures and use areas.

A camping facility suitable for scouts might also be suitable for other youth groups. This potential increases opportunities for revenue generation and to develop partnerships for facility development.

Renovation of this campground could focus on providing amenities, such as an organized group kitchen area, amphitheater, and some convenience camping units to better accommodate adult and family groups.

The existing dirt road up to this area would need to be improved for vehicular access, in particular to accommodate emergency vehicles.

There are currently no utilities in this area, which could be a substantial constraint depending on the level of improvements desired for the area.

Trail access should be created between Scout Hill and the lake so that campers can take part in canoeing and swimming activities.

Better drop-off arrangements are needed to reduce congestion on Lake Drive.

Flash Mountain Flash Mountain offers a good location for

cabins for the proposed retreat/event center at the adjacent Retreat House Complex (see Section 5.2.5). Retreat attendees would be within walking distance of the complex, and the overnight accommodations could increase the revenue potential of the complex.

This site provides great views of the lake. Existing trees would serve to screen proposed cabins from view of residents and campers across the lake.

The gradient of the area would allow a lower set of cabins to be sited without obstructing views for cabins located at higher elevations.

Rainbow Camp As with Dogwood Camp, the tendency for

groups at Rainbow Camp to be disorderly may be exacerbated by the fact it is so far from park headquarters.

Providing low barrier fencing at the outer edge campsites next to Hazel Creek would not only help define the usable areas for each campsite but would also provide additional protection for the creek area.

Rainbow Camp is the flattest of the three east end group campgrounds and is especially suitable to accommodate tandem parking



spurs. There is also sufficient area to provide a more communal campground environment.

Kamloop Camp Disorderly conduct by groups at Kamloop

Camp may be exacerbated by the fact that the campground (like Dogwood and Rainbow) is so far from park headquarters.

Providing low barrier fencing at the outer edge campsites next to Hazel Creek would not only help define the usable areas for each but would also provide additional protection for the creek area.

Gradients at Kamloop are a little steeper than Rainbow but are still suitable for tandem spurs. Although space is more limited than at Rainbow, there should be sufficient area to provide a more communal campground environment.

Black Oak Equestrian Camp Black Oak is very popular with equestrians

and seems, with little exception, to meet their needs. However, as with the other campgrounds, renovation of this campground would improve its utility, function, and environmental conditions.

Group Campground The Group Campground consists of five

group campsites, so designated by their numbers. Naming the campground and campsites could provide an opportunity to recognize key figures in EID history. It might also provide more clarity when referencing sites for operational or reservation purposes

This campground would be a desirable location for shower and/or laundry facilities given the high number of visitors and proximity to potential retreat facilities at the Retreat House Complex.

4.12.3 DAY USE AREAS Each SPRA day use area is unique and presents its own specific opportunities and/or constraints for recreation use.

Main Day Use Area The main day use area is very narrow, fairly

steep, and heavily treed. Reconfiguration to improve use of the area would require the design of ramps, stairs, and terracing. The construction of such improvements could damage existing trees.

Pinecone Day Use Area The proximity of this small day use area to

the water makes it a desirable spot for family picnicking.

The Pinecone Day Use area is adjacent to Pinecone Camp. On busy summer weekends, there is competition between both groups for use of parking spaces.

Sierra Day Use Area The Sierra Day Use area is on a narrow

peninsula where visitors can be on land yet feel like they are on the lake.

Due to its proximity to campsites, it is not uncommon for conflicts to occur over parking or intrusion into campsites.

Stonebraker Day Use Area Proximity to the Liberty Nature Trail at the

east end of the parking lot makes the Stonebraker Day Use area a good location for interpretive features such as signage or a kiosk.

Existing day use sites could be reconfigured to eliminate the one on the steepest slope and create a new one on flatter terrain east of the parking lot.

A better trail is needed from this location to the shore.

Chimney Day Use Area One of the flatter day use areas, Chimney

offers picnic spots in the sun or shade next to a shallow beach area where children can wade.



The parking area adjacent to Lake Drive is not delineated, making it somewhat inefficient.

Two remnant rock chimneys offer a unique sense of historical interest.

In the fall as the water level in the lake drops, the beach area can become very muddy.

Hazel Creek Day Use Area Located at the mouth of Hazel Creek, this

meadow area is unique to SPRA in contrast to the steep hillsides and conifers that generally dominate the park.

This location at the transition between the developed and undeveloped sides of the lake functions as an informal trail staging area for hikers. It also serves as a rest spot at roughly the half-way point on the loop trail (from the main entrance) for hikers, bikers, and equestrians.

Hazel Creek Day Use area has sufficient room to accommodate designated, delineated parking for day users as well as a kiosk with information about trails, history, and natural history.

Marina Day Use Area Because the parking lot occupies the majority

of the Marina, there is no opportunity to expand this day use area.

A shade structure of some type over the two existing tables would make the area more pleasant to use in the summertime.

Bumpy Meadows Day Use Area EID has received grant funding to construct a

day use area and multiuse trailhead at Bumpy Meadows east of the second dam. These improvements would address visitor access and usage issues near the dams, and provide some equestrian staging capacity. This area currently experiences heavy unauthorized day use, including fishing and picnicking. Visitors tend to park their vehicles on the

shoulders of Mormon Emigrant Trail creating traffic and safety issues.

It is currently possible for people to access this area without entering through the main gate and therefore not paying fees. A great deal of trash is associated with activity in this area and the maintenance required is not offset by use fees. Creating a designated day use area with trash receptacles and a fee box may reduce this problem

4.12.4 TRAILS Opportunities

SPRA trails provide visitors the opportunity to enjoy the natural resources of the park and be physically active at various levels and abilities. The shoreline trail is relatively level in many areas along the west and north shores but can be somewhat challenging in spots where the slopes are steep. Water and rest stops are frequent along this part of the trail, making it attractive to families with young children and older folks.

The trail along the south shore can provide a quieter experience, depending on the number of people on the trail, for those who like to hike longer distances and don’t mind the lack of facilities.

The entire Old Scaling Road is contained within an area being considered as the preferred location for the Sugarloaf Fine Arts Camp. It may be possible to accommodate a designated equestrian trail staging area in some portion of the proposed parking for the camp.

Mountain bikers typically prefer more challenging terrain than pedestrians or equestrians. Developing a dedicated mountain bike trail would help reduce user conflicts and increase SPRA’s appeal to mountain bikers.

Constraints Many areas of both the equestrian and

pedestrian/bicycle trails are in poor condition



due to erosion problems that create potential hazards particularly in areas where shore erosion is creating drop-offs ranging from 1.5 to 8 feet high.

Mixing different types of trail users on narrow or blind sections is a source of user conflict and potential safety issues.

Some unmanaged equestrian staging is currently occurring at the undesignated area along the Old Scaling Road. The configuration of the Old Scaling Road requires that horse trailers enter from the east end, generally requiring a left-hand turn across Mormon Emigrant Trail on a long curve offering limited sight. Due to these conditions, the USFS, which owns the road, will require that access to the area be moved to improve safety.

4.12.5 EXISTING STRUCTURES Park Headquarters and Maintenance Complex

The current configuration of the park headquarters office building is very inefficient and would not work to accommodate additional uses without major remodeling, especially to address Title 24/ADA issues.

The adjacent upper maintenance yard is large enough to accommodate another new maintenance building, which could replace the smaller, dilapidated storage shacks.

Because of its location on Sly Park Road and proximity to the main park entrance, this would be a good area for a museum and/or visitor’s center. Such a structure should be sited to avoid impacting traffic entering or leaving the park.

Retreat House Complex The Retreat House Complex is isolated

enough from other use areas to be an ideal location for a retreat/event center. The scenic views from the site and forested setting could

make it a very marketable venue for such uses.

The house at the Retreat House Complex is currently being renovated to improve accessibility with the intention of renting it out for group meetings, seminars, or retreats.

With the addition of a large deck on the back side, the house would be attractive for special events, such as weddings, receptions, and small parties. This could generate significant revenue for SPRA.

The presence of kitchen facilities in the house enhances opportunities for catering at scheduled events and activities.

The existing maintenance and shop building could be an ideal workshop for crafting classes, such as pottery, woodworking, or stained glass, with little modification.

The large, gently sloping area off the northeast corner of the complex could be used for outdoor events. Developed with a pavilion and nice gardens and given the backdrop of the lake and Sierra Nevada mountains, this area would be ideal for weddings, receptions, or reunions.

The garage could potentially be remodeled to provide indoor support facilities for such functions. It is conceivable that two events could be held concurrently, depending on the size and needs of each event.

The area southwest of the buildings is suitably large and flat to provide adequate parking for events.

Utilities at the complex include propane gas, electricity, and a septic system, but no phone service. Bringing some sort of phone and internet connectivity to the complex would be desirable to provide communications access for various seminars or other business functions, and in case of emergencies.



4.12.6 PROGRAMS Opportunities

SPRA offers exceptional opportunities for a variety of interpretive programs that could help attract visitation during non-peak periods.

The Miwok Nature Trail provides an opportunity to learn about the local Native American population and the natural history of the area.

There may be opportunities to offer recreation programs or classes in cooperation with other entities, such as the City of Placerville or Folsom Lake College (El Dorado Center), including kayaking, canoeing, fishing, natural history, wildflower walks, and trail riding. These types of classes could also be offered through volunteer-coordinated efforts.

SPRA could offer special packages for recreation programs in order to attract off-season and mid-week use. By requiring pre-payment or a deposit, it would be possible to gauge ahead of time whether there was enough interest in a program to cover costs.

It might be possible to develop a volunteer-vacation program, similar to those offered by the American Hiking Association, the Catalina Conservancy Job Corps, and the Sierra Club. Participants would pay a nominal fee to cover rustic camping or lodging costs and basic meals and participate in various volunteer projects, such as trail building, restoration, and bank stabilization.

Constraints Other than occasional volunteer-led nature

walks or cultural walks, there are no formal interpretive programs offered at SPRA. There are no staff positions dedicated to this purpose.

Recreation programming is generally a staff-intensive effort that requires the oversight of someone with experience to coordinate

programs and instructors. The primary constraints identified by SPRA staff that limit recreation programming at the park are lack of staffing and budget.

4.12.7 OPERATIONS Opportunities

Most SPRA senior staff have been working at the park for over 20 years. They know the area and visitors very well, as well as the history of how facilities and policies have evolved. Their institutional knowledge of the park and its operations is an invaluable asset.

SPRA is enjoying visitation from an increasingly diverse visitor population. Staff should be provided with professional training to help them understand cultural differences and recreation preferences. Such training will help park staff to deal with difficult situations and more effectively resolve user issues and conflicts.

Constraints Due to the addition of new Project 184

facilities, the existing staff are stretched extremely thin. Understaffing is already resulting in a backlog of improvement projects, deferred maintenance of facilities and grounds, and the inefficient utilization of staff.

Funding for park operations has lagged significantly behind the need for additional staff and facility improvements for many years. While there is a reluctance to increase fees and possibly limit access to the park for some visitors, either additional revenues must be found or the level of services reduced.
