Major Associates to evaluate the development and engineer.4 marina at the Waterfront Park location. This was accomplished through an analysis of: -background studies on the site, -river access requirements by the U.S. Corps of Engineers, PA DER and. PA Fish Commission, -data of similar marinas and area trends, and -related experience with similar projects. The analysis shows that the Falls Township site has significant advantages for the construction of an in-river marina. There is a strong economic market for the service. Engineering of the marina will focus on a permanent anchor system with removable docks. Fenced land storage will provide off-season protection for docks and boats. The in-river marina could ultimately service 200 boats although a 75 slip marina is suggested at this time. A recommendation is made to proceed with design of this marina when sufficient funding is obtained. Estimated costs of the described facilities are $648,000 with annual operating costs of $50,800 per year. (3) Falls Township Waterfront Park INTRODUCTION Project History Falls Township acquired 15 acres of riverfront property adjacent to the Pennsbury Manor State Historical Park. The intention is to develop this site into a recre.at@ional`_oriented waterfront park utilizing principally the Delaware River and also the adjoining wetlands, fields, picnic areas and proximity to Pennsbury Manor. The site is wedged between Scots Creek (a part of Warner Lakes) and the Delaware River. Planning for the Waterfront Park began in 1980 with a re- port by UNIPLAN (1). It called for three phases of development as follows: I . Passive Recreation- limited to providing site access, open fields and clearing underbrush, parking, picnic areas and pathways. II. Facilities for Dayboating- extend roadway, in- stall boat launching ramp, access, trailer, parking, a small vending building, gas tanks, and pumps. III. In-water Marina- provide slips for 100 to .150 boats and lan service utilities such as water, sewer, electric, parking and boat storage. To date, Phase 1 and part of Phase 2 has been completed. The site is open to the public, parking for 52 cars exist, picnic tables are located, fencing along Pennsbury Manor site is complete. In 1981, the township entered into an agreement with the Pennsylvania Fish Commission to lease 5 acres of the property for a river access facility. Surveys were started and a preliminary plan was prepared by the Fish Commission (2). However, an acceptable design was not obtained and funding was not authorized. obstacles to development centered on wetland impact and concern with the Pennsbury Manor Historical Park. Development of the in-water marina faced the same problem. Falls Township received a grant (fiscal 87) from the Pennsylvania Department of Environmental Resources (DER) Office of Coastal Zone Management (CZM) for furthering thd. marin.,a by obtaining design and engineering funding and coordination services. Accordingly, William G. Major Associates (WGMA) was retained to provide these services. This report. presents a compilation of findings and a design for a seasonal in-water marina at the Pennsbury Manor/Falls Township Park site. (4) SCOPE AND OBJECTIVE The scope of this study (3) focuses on preparing a preliminary engineering design of the marina complex and a final design of the river access. This was accomplished in a step-wise process as follows: 1. Data Collection 2. Evaluate Data-and recommend overall plan 3. Preliminary engineering design 4. Final design of dayboat access area 5. Funding 6. Coordination 7. Report preparation 8. Consultation (5) MARINA DEVELOPMENT ALTERNATIVES Site Selection A marina must have access to the body of water for which water dependent activities can be practiced. Falls Township has a frontage on the Delaware River extending from Tullytown upriver to Morrisville a distance of about 14 miles. The majority of this waterfront is owned by Waste Management Incorporated and USX Corporation. The Pennsbury Manor State Historical site, (William Penn's home) is waterfront property wedged between the large corporate holdings roughly two (2) miles up- stream of Tullytown corporate limits. Falls Township owns a 15 acre parcel adjacent and south of the Penns- bury Manor State site. This was obtained persuant to a study by Economic Research Associates (4). The Falls Township property is essentially rectang- ular; being 1000 feet of shoreline and 650 feet inland. From land, it is approached by Pennsbury Road, the prin- cipal access to the Manor, and is about 1.4 miles in from Bordentown Road. The land is almost level with a viewing mound exceeding 10 feet in height centrally located. There is a four'foot high dike which parallels the shore- line several hundred feet inland. The area between the dike and river contains man, large trees and the area Y inland of the dike is cleared grass fields and/or parking lot. No other Delaware River waterfront properties are available to the Falls Township for development as a river access or marina complex. Type of Service At the present time, there are no marina services at the Falls Township Waterfront Park site. An agree- ment exists with the Pennsylvania Fish Commission to lease five (5) of the fifteen (15) acres and install a boat ramp, comfort station and parking facilities. These facilities, and any developed for the marina would be oriented to the public recreational boater. Com- mercial operations would not be compatible for the public support services envisioned at this site. The recreational boating public in the Delaware River is seasonal in nature. Generally, the season ex- tends from April 1 to October 1. The major types of use include fishing; swimming, skiing and related water contact activities; cruising and sailing; live- a-boards, and racing. Improved water quality over the past number of years, coupled with an ac'tive boating public have raised the level of recreational boating on the Dela- (6) ware. Above Philadelphia the river has a deep channel maintained by the U.S. Army Corps of Engineers upstream to the Morrisville-Trenton Bridge crossing. Downstream of Philadelphia the Delaware is easily navigable to the Delaware Bay or south via the Chesapeake-Delaware Canal to the inland waterway and Chesapeake Bay. The type of services needed by the seasonal rec- reational boater in the navigable portion of the upper Delaware include the following: 1. Inwater slip or mooring facility for "permanent" and transients with cor- responding utilities (e.g. electric, water, sewer, telephone). 2. Security from damage by man or the elements and freedom of access for personal use. 3. Land related facilities such as rest rooms, showers, laundry, boat sales and services, ship store, fuel docks, bait, ice, phone, and winter storage. The degree to which each marina provides its services depends on its ability to capture and re- tain its market share. Many of the marinas in this area are open year round in order to keep sales, services and response current to user needs. it's not uncommon to find marinas in the Chesapeake area to have swimming pools, social rooms, golf courses, land transportation and similar facilities to attract the transient boaters. Table 1 presents a list of the services pro- vided by marinas in the market area of Philadelphia and north to Trenton. The "typical"marina in this area provides the following types of service: TABLE 1 MARINA SERVICES LAND STORAGE L A N D SUPPORT SERVICES ICE NO. IN- OUT'- WET BOAT BEV. SLIPS.

Major clubs in the vicinity of the Falls Township park include Bristol, Bordentown, Florence, Capital City, Anchor, and Pennsylvania yacht clubs. Typically, these clubs have limited dock facilities in the river and numerous moor- ing locations, sometimes on. both sides'of the navigable channel. Moored boats do not have the advantage of hook-ups for electricity and water and therefore cost savings can be realized by owners who do not need these services and who do not trailer their boats to access ramps. The type of services to be considered for the Falls Township Waterfront Park Marina should include,.- in-water docks, moorings, dry storage on land, service building for rest rooms, supplies and parking. River Access The Falls Township Waterfront Park property exhibits several development problems with respect to a marina, not the least of which is access to the water. The Delaware River is freshwater tidal in this area and there are general- ly two tides per day. The normal elevation change from high to low tide is about 61 feet. In the past, wetlands were generally viewed as waste- lands places infested with mosquitos@;,..biting flies, and snakes having little real or economic value (6). Because of the negative view and access to navigable waterways, wetlands were used for commercial development. Falls Township serves witness to this development with its utilization of riverfront for commercial purpose (e.g. USX Corporation, Warner, and GROWS, Inc.). More recently, wetlands are being recognized as important natural resources with many benefits to society. They are vital habitats for plants, and animals. They help improve water quality and reduce flood damages. They minimize the effects of upland erosion and they are beneficial to the hunting, fishing and tourism industries. This increased awareneFss has brought intense regulation toward any type of flood plain development. This has made "_perseverance" the keyword to progress with respect to marina development. The problem is crossing the wetlands. The objective is to minimize the impact on wetlands. The original plans (1) called for separate developments of a boat access ramp and a marina at this site. This would be similar to the Neshaminy, State Marina in Croydon which has.-separate.facilities. However, both the access ramp and the inarina require impact on the wetlands. An alternative approach is to construct an. in-river marina with a common access. In order to do this, it is first necessary to de- velop an approved access structure. Numerous alternative river access plans were considered and twa basic alternatives were drawn up for further considera- tion. They are: Alternative 1- Dredged channel and turning basin with sheet piling and ramp inland. Alternative 2- Filled in staging area and ramp over wetlands to river. Both alternatives were presented to various local, state and federal officials to obtain input as to a preferred direction. Appendix Drawing 1 attached presents the compromise position which has been submitted for permitting. The selected river access design has a raised staging area and driveway to the ramp which projects into the river well below the mean low water level. The structure is open underneath to permit tidal flushing. It is built on wooden pilings with precast concrete decking. The ramp is wide enough for two accesses at once, both using the center floating dock. This center dock will also provide level access to the in-river floating marina that will be connected to the end section. other land possibilities planned for the river access site include parking for 58 cars and trailers and a comfort station. (10). MARINA DESIGN CONSIDERATIONS Physical Conditions The river access location at the Falls Township Waterfront Park is shown in Appendix Drawing 1. The access is located 116,000 feet upstream of Allegheny Avenue in Philadelphia in accordance with U.S. Army Corps of Engineer stationing. It is about midway along the Kinkora Range on the opposite side of the channel from the flashing red marker number "72". The terminal pilings of the access ramp are 350 feet from the nearest edge of the Kinkora Range navigable channel. It is within this 350 foot area that the planned marina will be located. There is not an approved pierhead or bulkhead line in this vicinity that would interfere with the placement of a seasonal marina. A bulkhead does exist in front of the adjoining Pennsbury Manor property.. Drawing 2 presents photographs of the proposed site at high and low tide and. up and down the river. Clearly, the bulkhead at the Manor is not used for boating purposes but merely to protect the lawn against erosion. The in-river marina would be subject to conditions not present in a sheltered backwater location. Some conditions would be advan- tageous and some not so. Table 3 presents a list of considerations in this regard. The advantages are sufficient "as is", but the disadvantages need to be addressed separately. Ice Flows - The Delaware will occasionally freeze over during the winter, which when coupled with the rise and fall of tides gen- erates large vertical and horizontal forces on any structure. The floating docks will be securely stored on land at this time and the fastening system will need to be protected from these forces. Runaway - Large commercial ships use the navigational channel with tug escort/power. It is possible that a ship could wander from the channel if lightly loaded and do damage to an in-water marina. A breakwater would prevent this mishap, but the probability of such an event is too small to warrant the cost of such protection. Boat owners insurance would no doubt cover vessel damages and the marina would need a blanket policy for the dockage system. Floating Debris - It is not uncommon to find floating trees, .55 gallon drums, tires, plastic containers and similar items flowing out with the current. These items rarely have enough impact force to do damage to standing boats or docks. However, they can accumu- late and become entrapped around pilings, outdrives, lines, etc. This will present a maintenance requirement which should not be allowed to get out of control. Table 3 Considerations for an In-River Marina Location Advantages �Lower initial investment �Close to "the action" for the boater �Fresher water conditions �Self cleansing of sediment, pollution �More scenic �Less impact on wetlands and land based recreation facilities Disadvantages Subject to off season ice flows Run away barge or uncontrolled ship Floating debris in river Current flows and changes, particularly extreme high and low Require "no wake" conditions in river Little protection from wind force (12) Current Changes - Tides are vertical changes in the water elevation and currents are horizontal flows. At the marina loca- tion in Falls Township, no current (slack water) and maximum cur- rent each normally occur four times per day. From a slack current, the flood current upriver occurs to a maximum rate in about three hours and then subsides to another slack condition three hours later. An ebb flow then increases downriver for about three hours and then subsides to another slack current. This sequence is re- peated in the second 12 hours of the day. Vertical motion follows essentially the same cycle but may not peak at the same time as the currents. Vertical motion may be affected by extreme flood flows in the river caused by upland rains rather than by the moon's gravitational effect. For this reason, the marina should be de- signed for elevations to the 100 year event for the high point and in deep enough water to provide sufficient draft in a low-low tide condition. "No Wake" Condition - This condition will take a section of the river and remove it from free boating. Boat wakes are waves that can do damage to other boats or docks that are Jostled against docks, pilings, bulkheads or other boats. Posted "No Wake" signs are usually sufficient to slow boaters down and prevent this dam- age. However, this is a straight section of the river which is frequently used by skiers so that the loss will not go unnoticed. Moored boats are usually not as vulnerable to wakes because they do not rub against a fixed object, but they take more space than docked boats, so the trade off of centralizing in-water boat stor- age may actually increase sections of the river for free boating. Wind Forces - A sheltered marina would tend to provide pro- tection from hurricane type winds. The design of the in-water marina should consider winds to 100 m.p.h. This force, coupled with maximum flood current and a safety factor should provide a sound basis for securing the dock system. Individual boats will be fastened with lines of sufficient strength to prevent leaving their berths. Wave forces generated by wind across the water surface will not be a major problem because the prevailing winds will have a relatively short fetch length. This means that large waves will not be produced as might be the case at the edge of a large lake. Dock System- There are several major dock manufacturers that will construct systems adequate for this installation. Because the tide change is in excess of 6 feet,it will. be necessary to have a floating system, rather than a fixed one. Also, the individual units must be easily disconnected and removed for off-season storage. (1-3) Built in utility channels along the main docks should carry .as a minimum fresh water (portable hose connections for cleaning, fire protection) and electricity (boat hookups and dock lighting). Winter Storage winterizing boats in this area requires action on hull clean- ing, motors, outdrives, pump systems, heads, pressurized water sys- tems, batteries and other temperature affected systems. Once done, the boat is covered from the elements and supported in a manner that insures stability. The boatyard merely has to provide a secure area. In-water winter storage would not be possible at this location due to the inability to control ice damage. Secured areas should be as follows: 75 Boats - 26,000 Sq.Ft. 100 Boats - 35,000 Sq.Ft. 200 Boats - 70,000 Sq.Ft. This maximum area would require about three quarters of the parking area required for the access ramp. Therefore, we consider fencing a portion of the parking area to enable winter storage of docks and boats. Parking At present, the Waterfront Park has 52 normal size asphalt parking spots which are used for the picnic area and any other activities (including marina) at the Park. The River Access plan calls for an additional 58 double spots (tow car and trailer). This should be sufficient parking for the initial 75 boat marina and perhaps more depending on use. The most critical time will be the hot Sunday in July when everyone wants to be on or near the water. During these periods, parking on the grass along the en- trance drive would be sufficient for an additional 90 cars. This would total 200 cars. At three (3) people per car, this would be a total service population for 600 people. Water and Sewer Requirements Men and Women's restrooms will be provided for the River Access phase of this project. The water supply necessary for the marina should service the total user population,i.e.600. At 10 gallons/person per day for 600 people, this represents a flow requirement of 6,000 gallons per day. The ground water bearing strata in this area is unconsolidated sand, gravel and clay depositc. with wells yielding 200 to 3,000 gallons per minute. Water quality is fair. A holding tank--inthe order of 5,000 gallons will be suffic- ient to service the restroom facilities. (14) Boating Market and Economic.s The 1980 ERA report (4) concluded "....market support exists for an additional 100 to 150 slips on the upper Delaware River." The intent here is to determine if conditions have changed to warrant a different conclusion. Table 2 presents statistical data and trends related to boating registration, population, income, and visitor attendance at Pennsbury Manor. Pennsylvania Boating registration has increased at the rate of 3.19 percent per year. This rate compares favorably with more current data presented by the National Marine Manufacturers Association-(NMMA) (8). They have indicated five straight years of sales gains for the industry with 1987 being about 5 percent better than 1986. Furthermore, their analysis suggests that the boat buying public (35 to 54 year olds) is expanding as the "baby boomers" travel through this group and that this alone will support a 4 to 6 percent annual growth rate for boating through the year' 2000. From 1980 to 1983, the Bucks County population increased at an annual rate of 1.7 percent. The trends of more people with more money available would support the original premise that a market exists. In 1980, ERA (4) selected 10 marinas in the upper Delaware that were significant in terms of the number of slips available and services offered. These marinas had 1153 slips available in 1980 and these same marinas have 1608 slips available in 1987. This represents an annual average increase in the number of slips in the amount of 7 percent per year. In addition, a major marina on the Neshaminy was not included in the 1980 report, i.e. the Snug Harbor Marina in Croydon which has 200 slips. Another new marina in the City of Philadelphia, the Philadelphia Marine Center has 350 slips that Were not included in the 1980 report. 91e increase in the number of slips available (7%) is higher than would be indicated from either the increase in Pennsylvania boater registration (+3.9%) or in new boat sales (4 to 6 %). It is interesting to note that the majority of new slips are in New Jersey and that Pennsylvania's rate of increase for new slips is about 0.5% per year.

However, it appears that the seasonal cost per foot of boat has risen from 10$/ft. in 1980 to 40$/ft. in 1987. After adjusting for inflation, this still represents an increase of more than 14 percent per year. Clearly this implies that a strong demand exists for in-water boat docking. Additional fees would be collected by the marina for electricity and winter storage plus any mark-ups for supplies, food and the like. Winter storage in a securd 'outdoor area could run from 10 to 20 dollars per foot. A representative mix oj'--' boats in a seasonal marina on the Delaware would be suggested as follows: Average length 23' and under- 60 percent 20' 23' to 35' 30 percent 30' over 35' 10 percent 40' A seasonal marina fully used with the above mix of boats at the average dock and storage fees would realize an annual income of: 75 BOATS 100 BOATS 200 BOATS $103,000.00 $137,500.00 $275,000.00 In reference to ERA's conclusion that a market exists for a new marina, it is apparent that the boating public is willing to pay for these services. The upper Delaware has had a significant increase in the number of slips over the past seven years and yet the fee per slip has risen dramatically. Perhaps the lack of adequate river access ramps is forcing the boater to stay in the water. Maybe the overcrowded c;onditions at the Jersey shore, coupled with higher dockage rates ($100/ft) salt water and associated pollution problems are directing the boater to keep the boat closer to home where it can be used more fre- quently. Maybe the aggressive sales organizations in the vicinity of Croydon, PA, Dredge Harbor, NJ and the Philadelphia Marine Center are selling boats faster that the national average. The improved water quality in the Delaware, the decline in large commercial traffic, the easy access to the upper Chesapeake Bay and the availability of disposable income have all been factors that substantiate the conclusion that a new marina in the Falls Township site would receive strong market support.

The initial cost of systems depends on the size of members, the extent of utilities (water, electric, lighting, fire protection, cleats, etc.) and the pricing market at time of purchase. Accurate costs for these systems can be obtained through a public bidding process once permit approvals have been obtained. For purpose of estimating project costs at this time, 1988 MEANS Catalog of construction costs. has been used which estimates per slip costs ranging from $2,225 to $5,725. Key factors in the selection of a dock system include durability, appearance, stability for various live load conditionst ease of installation and removal safety for people and boats. See Appendix B - Representative Dock Systems. Anchor System The most common anchor system for marinas in the upper Del- aware are creosoted wooden pilings. They are in good supply, easy to install and relatively Permanent for the marine environment. We have a concern with use of piling for an in-river marina as opposed to the other backwater marinas in the area. This is not related to interruption of river flow, because they will have es- sentially no daming effect. It is a concern with ice damage which may tend to lift the piles as the tide rises. This may result in an additional significant operational cost by having to install a percentage of new pilings each spring. Al- ternative anchorage systems such as large concrete dead weights, telescoping piles, and removable caps may be considered if normal wooden piling is deemed unacceptable. For cost purposes, we have used wooden piling as the preferred anchoring system. The selection of an anchoring system would depend on the type of dock system selected. See Appendix B - Representative Piling System. Winter Storage A storage area has been reserved in the land side parking area to permit outside secure boat and dockage off-season storage. The access ramp will be needed in addition to a transport vehicle and storage blocks. Pressurized water cleaning of the hull as the boat comes out of the water eliminates the need for soaps and/or detergents later on. Winterizing of the boats can be done e1ther by the boat owner or a mechanic recommended/retained by the marina. The process of emptying the marina will depend on the availability of manpower and equipment and.will generally take from 4 to 6 weeks to remove all boats and docks and to secure them on land. The spring re-entry would be equivalent. Consideration can be given to expanding boat storage by constructing Hi-Dry units in the future. Several marinas in the area are going to this method which has the advantage of year (21) round protection from the elements and yet relatively easy river access. Operational Factors Maintenance and Repair - The marine environment is aggressive to most man-made materials. Metals, wood, fiberglas, plastics and the like are either actively corroded or used as habitats for marine organisms. A marina operator must be vigilant for these conditions and must have the: resources to correct problems before they become dangerous or out of control. Annual maintenance and repair operating costs generally vary from 2 to 8 percent depend- ing on whether it is for a permanent non-moving structure or for mobile equipment. For estimating purposes, we have used 4 percent of the pilings, dockage and storage facilities. Service Building - Shelter is necessary to provide a place for record keeping, to be a base of operations, and to focus a marina-wide security program. Also, it would be necessary if boat sales, repairs, and/or marine supplies were part of the oper- ation. These latter activities require more extensive consideration then is permitted in this report. Therefore, we suggest leasing a portable trailer type office! for the first several seasons to pro- vide the basic necessities. Market Identity - Consideration needs to be given to developing a market identity for the Falls Township Waterfront Park. The avail- able site is by no means "ideal". Within eyesight up river is the large steel making operations of USX Corporation. Just down river on the Jersey side are hulks; of the Roebling Steel Company. The Pennsbury Manor Drive to the site can not miss the activities of GROWS, Inc. These views are not easy on the Boater's eyes. The advantages of the site include proximity to Pennsbury Manor, passage through Penn-Warner Lakes to the site, pleasant wildlife@ and wetland vegetation along the river, and a gateway for the Bucks County boater to enjoy the river. Capitalizing on an advantage to form a market identity will be important on develop- ing a successful marina. Unlike the Neshaminy State Marina in Croydon which charges essentially one half the normal dockage fee and thereby maintains a five year waiting list, it is suggested that this marina use competitive rates. Access Road - Pennsbury Manor receives about 50,000 visitors per year. The bulk of these are during the summex months, holidays and the normal vacation periods. If we assume that three quarters of these visitors occur during the period of April 1 to October 1 on Friday, Saturday and Sunday, then the average weekend traffic to the Manor would handle 6411 people which, at two people per car would be 320 cars. Most of these cars would be traveling in the period of 10am to 4pm. (22) The river access site is designed for 58 vehicles and the initial marina for 75 boats. Normal weekend daily usage would be in the order of fifty percent (50%), which would mean 67 vehicles, coupled with an additional 30 cars for the picnic area and Penn Warner Lakes would put a total usage on the Pennsbury Manor access road of 417 vehicles. This rate of use would repre- sent a low volume driveway in accordance with PennDot criteria. We judge the present access is sufficient to handle the required traffic. Cost Estimates Preliminary Capital and Annual Operating Cost Estimates are presented in Tables 5 and 6. Total costs are based on: 1. 75 Slip Marina as previously described. 2. Storage area for initial phase. 3. River access site already developed by others including water, sanitary and a comfort station with holding tanks. 4. Electricity available within 400 feet of site. 5. Layout of docks and anchorage in accor- dance with Drawing A3. The Total Capital Costs, including contingency is estimated. to be $648,000. Annual operating costs are based on: (1) initial phase marina as discussed above, and (2) leasing of service building and trailer lift vehicle for moving boats and docks in and out of the water. The annual operating costs are estimated for capi- tal amortization are not included in the annual costs. The amount of capital that would require amortization would depend on the grant money available from various local and feder- al sources. If we consider no grants (worst condition) at an interest rate of six percent (6%) for 20 years, the annual amorti- zation rate would be $648,000 X .08718 = $56,400. This figure, when added to the annual operating cost gives a total yearly cost of $107,200. Because the annual revenues are only $103,000(based on current average dockage and storage fees of $55/ft.), there will be a short fall of $4,200 per year until the user fees in- crease (at a rate of fourteen percent (14%) per year, this would take less than one year), or unless sufficient grant monies can be obtained to reduce the amount of amortization.

This report will provide'a basis for permitting to construct and operate an in-water marina. Pennsylvania has a joint permit process whereby one application (in triplicate) is made to the Pennsylvania Department of Environmental Resources and it is distributed to the Philadelphia District Corps of Engineers and the Pennsylvania Fish Commission. This process can take as little as 45 days, but more likely for this.size project it could take 6 months or more. Detailed engineering of the dock and anchor system will consist of in-water hydrographic surveys, core borings and sizing of docks, utilities and anchor systems. The hydrographic surveys should obtain data on instream velocities, water quality analysis, water depth over the entire proposed area and water flow levels at Trenton during the sampling period. These data in conjunction with tide table, wind charts, current charts and the like will provide the basis for detailed engineering analysis on the structural integrIty required for the in-river marina. once the structural members are designed and the systems are specified, detailed construction cost estimates can be made. Funding for the marina can be accomplished through a combination of federal, state and local sources. Federal sources include those administered by the Pennsylvania Coastal Zone Management (CZM) Program which receivest` - grants from the U.S. Department of Commerce's National Oceanic and Atmosphere Administra- tion (NOAA). This funding is normally limited to 50,000 dollars per year and requires that the project be designed and engineered before application. Also, there must be at least 30 percent local matching funds and a good indication that permitting will be approved. A possible source of state funding is the Pennsylvania Fish Commission. However, because the Fish Commission would be involved with construction of the river access site, it is unlikely that large amounts of additional funds might be available for this development. Another possibility for state funding might be the State Park Department. The Neshaminy State Park operates the state marina in Croydon and it operates the Pennsbury Manor next to this site. Perhaps the township could interest the State Park Depart- ment to assist with this development. An alternative idea, based more on private financing would be to approach Penn-Warner recreation club to determine if interest exists in combining the public marina and the Penn-Warner Lakes. The Penn-Warner lakes are a privately operated recreational area which adjoins the site on its south and west boundaries. Electricity,access road, and to a certain extent security, are A26) shared at present. The lakes are owned by Waste Management, Inc. which operates the nearby GROWS, Inc. Sanitary Landfill. Start-up funding could be obtained from a general obli- gation bond to the Township. Under the worst case condition, (i.e. no grants), it would take a year or so before revenue would exceed operating costs depending on level of use, fees, and operating conditions. Permitting for the River, Access Facility was initiated f ormal- ly by application of a revised Joint Permit on November 2,1987. Notes of the meetings and related documentation is included in Appendix C. (27) CONCLUSIONS AND RECOMMENDATIONS Conclusions Based on the findings of this report, several conclusions are presented regarding the development of a marina on the Delaware in Falls Township: 1. The existing Waterfront Park presents a site suitable for a marina. 2. The presence of valuable wetlands at the site restrict the options for development while enhancing the boating experience. 3. A river access built over the wetlands to the navigable portion will double as an access for an in-river seasonal marina. 4. User fees for marina slips in the upper Delaware are increasing at a rate (14%) twice as fast as slip availability (+7%) and more than three times faster than boater registration (+3.9%) in Pennsylvania. 5. The marina's anchor system must be designed to with- stand winter freezing condition as well as extreme high flows. 6. winter storage is a service that most marinas in the region provide. 7. A marina does not require a fully dedicated on site service building, but rather a record keeping office. 8. A market identity would help establish a clientele. 9. The Pennsbury Manor ac.ce.s:s road and existing parking area (including the! proposed river access site) are sufficient for the marina development. 10. Construction grant funding would improve the likeli hood of self-sustaining economics. Recommendations 1. Assist and coordinate with the Pennsylvania Fish Commission in the construction of a river access at the Waterfront Park site. 2. Apply forCZM funding for continued design of an in-river seasonal marina. (28) REFERENCES 1. UNIPLAN REPORT, 1981, by Uniplan Associates, Princeton, N.J. 2.

UNITED MC GILL CORPORATION TECHNOMARINE Technomarine, Inc. manufactures and installs the finest floating dock systems available in today's world market. Competitively priced and fully warranted for two years after installation, these systems can be adapted to any salt, or fresh water application -- from a private boat dock to a fully equipped marina complex.. The Technomarine system uses a modular, adaptable approach to meet the requirements of each specific application. The supporting framework of the system is composed of weather-resistant ' nickel- aluminum alloy, buoyed by durable polyethylene (Marlex) floats filled with styrofoam. All surface walkways are copper-treated southern pine, which lasts for many years. Water, electrical and cable hook-ups to each slip are easily incorporated (and inspected) by use of utility channels along both sides of every main walkway. All materials and parts are designed for maximum flexibility and low maintenance costs in the event. requirements change. Every system proposal prepared by our engineering team receives exacting attention to detail and technical requirements. Prospective customers are interviewed and asked to fill out a thorough questionnaire that will enable the best product match to the specific application. Once this has occured, an on-site visit, followed by another interview is required. After this process, Technomarine will provide (at no cost to the prospective customer) one or more planned system alternatives. Technomarine has sold floating dock systems, breakwaters, work barges, fishing and ferry vessels tn the United States, Canada, Europe and the Carribean.

E Catwalks: bilateral, unilateral or articulated I n general, the main walkways are Vt, 7: equipped with catwalks or bilateral cross- walks in one piece, bolted to the main 4_5 walkway. The catwalks are provided with floating stabilizers at each end thus con- tribute to the firmness of the whole struc lure with their resistance and flexibility to the movement of the water. The ends of the catwalks are covered with a pliable protection of ethafoam. The length (3.6 to 10 metres) and width of the catwalks varies according to the customer's requirements. Each customer is assured of adequate advice from our technical department to complete an esti- mate of a project. The lateral resistance of a 10-metre catwalk has been calcu- fated depending on the mooring of boats upto 15 metres. Articulated unilateral cat- 7@' walks are especially designed to be used #.3 for the mooring of boats at an already existing dock. The resistance of each type of catwalk f we construct has been studied. They are fixed to the main dock by galvanized steel bolts. 7 TECHNOMARINE Access bridges and fastenings . ........ Technomarine offers several types of co rinecting bridges and fastenings to meet problems arising from tides, changes in water levels and other matters relating to a dock or a marina. A-@ We examine all the conditions and advise our customers accordingly with each order. V%A-'VT,' Dead men anchor or plies The Technomarine system uses four 7:y methods of keeping the docks in place: dead men anchor, piles, connecting A-arm and guiding rail. We recommend the method that best suits the conditions of a particular project. For anchoring, galvanized steel chain is used to join the central passage rail to blocks of concrete whose mass is geared _7 a to the conditions of the place. Where plies are necessary, they are inte- grated to the central unit and a system Ja of rubber rollers permits verl ..AJ ical move ment to adjust to tides and water levels. Troughs and fosterings The Technomarine dock system includes all necessary boat mooring accessories such as stirrups, fenders, water faucets, electric connections, etc. Utility points can be installed at regular intervals, providing power and lighting outlets. Water faucets are built directly into the planking. The water and electrical conduits can be placed on either side of the main walkway in a special trough with an aluminium covering. - 4@z' ,6-0-1 TECHNOMARINE NEW NEEDS, NEW METHODS For some years the popularity of recre- ational activities has demanded that docks be available where there is water and the growing requirements of the 2, groups and invidivuals involved in this field led Technomarine to develop a sys- tem of pontoons and floating docks of Ir4t., exceptional quality. The quality of the materials used, the ingenuity of the Technomarin e system, 7t the study of most of the problems encountered in the development of docks for private users or marinas and the expertise of the Technomarine technical team are the best guarantee for exacting customers. The Technomarine system is durable, fle- Able, resistant, modular, maintenance a free, easily dismantable, much lighter than traditional docks and meets all safety and environmental standards. During the last dozen years, more than 20 kilometres of docks built with this ------ technique have been installed in Europe, the United States and Canada: on salt water and fresh water, in regions having enormous variations of temperature, on ------- rivers where currents and tides are con- siderable and on surfaces of water requir ing ingenious arrangements.

Notes of Meeting Falls Township Project W.G.M.A. No. 7017 Date and Place of Meeting: October 16, 1987 @ PA Fish Commission Office-Bellfonte, PA Attendees: Eric Conrad-Coastal Zone Management Jim Young, John O'Brien, Tom Snyder, PA Fish Commission T. Cadwallader, W.G.M.A. The prupose of the meeting was to review the current plans and costs of the proposed river access at Falls Town- ship Waterfront Park. A summary of the major discussion items is as follows: 1) Eric presented a background of CZM funding for this project and the subsequent marina develop- ment. 2) Tom presented the original alternatives and rationale for development of the current plan. This plan calls for wooden pilings with an elevated deck leading to the ramp which extends over the wetlands to the river. A floating center dock is used to enable ta:. accesses at once. 3) Project cost estimate of $397,500 was distributed. This is about $6800 per parking space which is well above that typically constructed by the Fish Commission. 4) A question was raised aS to keeping pilings stable during winter freezing when there is a tendency toward upward pressure. 5) Funding source was raised. PA Fish Commission has bulk of 87-88 dollars budgeted. Ed Miller and the Commission Members would have to redirect budgets to permit funding this year. Jim Young is to meet with Mr. Miller next week and will discuss the project. Re-programming access/marina projects is not impossible. 6) Normally the PA Fish Commission constructs its own access ramps. A 400,000 dollar ramp would be one of the largest undertaken to date. They. subcontract piling work. 7) Cash awards can be made by the PA Fish Commission although they normally contribute through work services. TEC:lcm RECEIVED September 16, 1987 SEP 21 1987 WM G MAJOR ASSOC Thomas E. Cadwallader William G. Major Associates, Inc. 108-110 Mill Street Bristol, PA 19007 Dear Mr. Cadwallader I surveyed the site of the proposed boat launching facility along the Delaware River just south of the Falls Township Park on September 5, 1987. The following description applies to the area designated by stakes in the ground. The bank of the Delaware River consists of a 60 - 75 foot wide fresh water tidal marsh. The marsh shows zonation typical of this habitat. The lower two-thirds is dominated by Nuphar advena with an understory of Sagittaria subulata. There are scattered small patches of Scirpus americanus and Eleocharis sp. The upper one-third of the tidal marsh consists of Nuphar advena, Pontederia cordata and Zizania aquatica as co-dominants with occasional patches of Sagittaria subulata and Eleocharis sp. On logs and stumps at the high tide line additional herbaceous species are found including: Lythrum salicaria, Eupatorium perfoliatum, Vernonia noveboracensis, Polygonum punctatum, Pilea pumila, Juncus tenuis, Panicum virgatum and Lycopus americanus. Adjacent to the river bank is a floodplain forest dominated by Fraxinus americana and Acer negundo. Other canopy trees include Quercus bicolor, Ulmus americana and Prunus serotina. A single large specimen each of Liriodendron tulipifera and Acer saccharinum. also occurs in this area. Shrub species include Lindere benzoin and Viburnum prunifolium. The herbaceous layer of this forest contains scattered clumps of Asarum canadense and Arisaema triphyllum. Dried stalks of Alliaria officinalis are also present. Of the species listed above, Sagittaria subulate and Zizania aquatica are included in the Pennsylvania Plants of Special Concern list where both are classified as Rare. Not found at this site, but noted nearby are Biden bidentoides (listed as Threatened in PA) and Amaranthus canabinus (listed as Rare in PA.) Sincerely, Ann F.

Box 603 Bristol, Pennsylvania 19007 Dear Mr. Cadwallader: In response to your letter dated July 17, 1987, 1 want to apologize for not responding before August 15, and to thank you for your patience with the Fish Commission. After reviewing the notes of the meetings with DER, the Corps of Engineers, and Coastal Zone Management, and after reading the comments from our own people, it is very apparent that everyone agrees that Alternate Plan 1 is preferable. It is recommended by the Fish Commission that the turning basin be eliminated and the matter of "who will do the dredging" will have to be resolved. Also, before this project can be put on any construction schedule, the money for the project will have to be budgeted so it is imperative that a cost estimate be furnished as soon as possible. It is also recommended that any further inquiries be addressed to the following gentlemen as they are the ones who are instrumental in budget decisions: Mr. James:Young, P.E.i@-Acting Director Bureau of PropertV & Facilities Management Pennsylvania Fish Commission 450 Robinson Lane Bellefonte, PA.:`16823 Edward R.

Eng. Tech. Division of Fisheries Environmental Services In response to your July 31 , 1987 memo, as you noted, the Pennsbury Manor ramp development is certainly complicated,by the Delaware's tidal influence at that location. The two schemes presented by William G. Major Associates appear to overcome the "mud flat" problem and would allow boat launching and retrieval at various tide stages, but each presents several negative features. From an environmental -standpoint, both plans involve fill and/or excavation of tidal wetlands and shallow water river habitat and would.obviously require DER and COE permitting. As you know, these regulatory agencies and the other commenting groups carefully evaluate these types of activities, particularly in terms of potential cumulative impacts to the resource. Based on past experience, it is expected that the applicant, in this case the consultant, will have to provide detailed analysis of all available alternatives, including possible development at other sites. Water dependency is certainly satisfied by the nature of the project, and the public benefit aspect also would contribute to positive recommendations from the review agencies. Assuming it can be reasonably demonstrated that no feasible alternatives exist, permit issuance, possibly with mitigation requirements, would be likely for either design, with Alternative 1 being the most acceptable because of the minimal fill required. As discussed, fill associated with this plan would mainly consist of riprap necessary to protect the sheet pile seawalls, and could be considered a fisheries enhancement. William G. Majors Associates has also presented both proposals to DER for preliminary review, and Khervin Smith advises that he discussed the above considerations with their'representative and also indicated a preference for Alternative 1--possibly with a reduced or eliminated turning basin pending a requested wetland assessment of the wooded area between the dike and the high water line. Thanks for the opportunity for early input, and let me know if you need anything else. RRT:dms cc: J. Miller STO-501 1 -84 COMMONWEALTH OF PENNSYLVANIA August 11, 1987 SUBJECT- Preliminary Proposals Pennsbury Manor, Bucks County TO: Jim Young, Acting Director Bureau of Engineering FROM: K. Ronald Weis, Chief Engineering & Architectural Division I wish to begin by expressing Tay real concern that we, the Pennsylvania Fish Commission, are getting backed into a corner if we allow this process to continue. It is true that we do have an agreement with Falls Township to construct an access area at this location) however, we must have sufficient monies budgeted to cover the cost of construction or we will again have pressure from legislators. We entered into this agreement without the full knowledge of the difficult physical problems that exists with this site. This was due completely to the Commission's negligence by not thoroughly investigating the site. In my review of the two alternatives submitted, both contain a common major problem which I can see no acceptable solution for. This problem is that both schemes create obstruction to the free flow of water in the Delaware River which poses two situations: (a) By forming an impediment to the flow of high water, a build up of back water could possible create flooding problems for the operators of the Pennsbury Mano 'r Historical site. (b) * The structure also will be highly susceptible . to ice damage during spring flows. Specific comments on the two alternatives are: Alternative one - in my opinion, is the preferable plan. The major difficulties are the projection of the metal pile channel into the river and the re- sulting maintenance dredging. Alternative two - in addition to projecting into the river, this provides a much more difficult launch situation because of a required 1800 turn of vehicles and trailers, a long backing requirement, and launching into the current.. In addition I have attached a copy of our. agreement as well as a memor- andum of May 12, 1980. My review of the agreement yields no discussion of an obligation for dredging on either party. jm cc: T. SnydeV,' J. O'Brien, J. Miller WILLIAM G. MAJOR ASSOCIATES, INC. P-e.

Rationale for the fill might include: a. prevent future dredging/maintenance considerations. b. promote public access/use to the river. 3. Need to coordinate with Ron Wise @ PA Fish Commission in Belfonte. 4. CZM funding - Earliest availability would be October 1, 1988 design and engineering must be done before application - $50,000.00 limit based on 30 percent matching local - need permits in hand or at least a good indication of availability. 5.

The following are major comments from the discussion: 1. The application should identify the wetlands and the presence and/or absence of rare and endangered spieces. Mr. Smith recommended contact with the Morris Arborptum. NOTE: Dr. Rhoads - 247-5777 Ext. 9144 Meadowbrook (who is on vacation until August 10) 2. The fill Alternative would be less desirable than the dredging because the later would increase wet areas, but consideration should be given to maintenance dredging for future use. The permit will include this requirement. 3. Sheet pile dredging would be preferrable to open dredging 4. A pile supported structure would be OK because it would allow flow of water under and on wetlands. 5. Mittgation will require a one for one replacement of any wetlands removed. 6. The Environmental Review GrouD meets the last Thursday of every month and would be a forurii -for input to the project. This months meeting will be in Erie, PA 7.

Two alternative plans were reviewed including 1) A dredged channel and turning basin, and 2) A filled ramp into the river. %,Comments and observations are as follows: 1. Preference for the open or dredged plan over the fill because of less impact on wetlands. 2. The dredged plan may not need sheet piling because the substrate may be stable- enough to maintain slope independently. 3. Perhaps a partially dredged channel and floating d6ck closer to shore would be a preferable alternative. 4. The dredged turning basin is discouraged unless there is a flushing stream to help water quality. Tidal changes alone might not. be sufficient. 5. Does the Township own any other lands that would have less impact on the wetlands? Not for this purpose. 6. Is there any feedback from the State Office of Historical Preservation? Yes, we are coordinating with Pennsbury Manor. 7. What is the proximity of similiar facilities in PA? Next one downstream in Bristol - none upstream. 8. The plan could be coordinated with all adjacent property owners, i.e. Penn Warner/GROWS. 9. Suggest meeting with Kervin Smith at DER (717-787-6827) since the 'permit system is now a joint effort starting at Kervin's office. (Note: I called and he is on vacation this week. I'll try to meet with him next week) Received a new Joint Application Form - disregard the previous two forms sent by.the Corps. WILLIAM G. MAJOR ASSOCIATES, INC. Page Two Richard Hassel July 24, 1987 10. If fill is necessary a 401 certification will be required from the Norristown office of DER. 11. Smith's office has an Environmental Review !Committee which may be helpful in getting input. 12. Delaware Valley Regional Planninq Authority has an Urban Waterfront Action Group (UWAG) which meets monthly if necessary. Keith Harrington (592-1800 ext. 137) can arrange a meeting (Note: I called and set up our presentation for 10 a.m., Aug. 11) 13. An aerial photo showing extent of wetlands would be a helpful addition to the submission application. All drawings for the permit. must be at 8 1/2 X 11 size for public notice purposes. 14. Depths of water should be referenced to mean low water. A channel depth of -5ft. would be preferable to 8 feet because of less impact on wetlands. 15. It maybe necessary to provide a 1 for 1 replacement of wetlands - perhaps by excavating a shoreline area to enable wetlands to develop. 16. The final permit will come from Corps of Engineers.
