C. Placing Piles
1. Piles properly placed and driven shall be interlocked throughout their length with adjacent piles to form a continuous diaphragm throughout the length or run of pile wall.
a. Piles shall be carefully located as shown. Piles shall be placed plumb with out-of-plumbness not exceeding 1/4 inch per foot of length and true to line. Place the pile so the face will not be more than 6 inches from vertical alignment at any point. Top of pile at elevation of cut- off shall be within 2 inches horizontally and 2 inches vertically of the location indicated. Manipulation of piles to force them into position will not be permitted. Check all piles for heave. Redrive or replace all heaved piles to the required tip elevation.
2. Provide temporary wales, templates, current deflectors or guide structures to ensure that the piles are placed and driven to the correct alignment. Use a system of structural framing sufficiently rigid to resist lateral and driving forces and to adequately support the sheet piles until design tip elevation is achieved. Use two templates, at least, when placing each pile. Templates shall not move when supporting sheet piles. Fit templates with wood blocking to bear against the web of each alternate sheet pile and hold the sheet pile at the design location alignment. Provide outer template straps or other restraints as necessary to prevent the sheets from warping or wandering from the alignment. Mark template for the location of the leading edge of each alternate sheet pile. If in view, also mark the second level to assure that the piles are vertical and in position. If two guide marks cannot be seen, other means shall be used to keep the sheet pile vertical along its leading edge.
D. Driving Piles
1. Prior to driving piles in water, paint a horizontal line on both sides of each pile at a fixed distance from the bottom so that it will be visible above the water line after installation. This line shall indicate the profile of the bottom elevation of installed piles and potential problem areas can be identified by abrupt changes in its elevation. Drive piles with the proper size hammer and by approved methods so as not to subject the piles to damage and to ensure proper interlocking throughout their lengths.
2. Each pile shall be driven continuously without voluntary interruption, from the first blow until the penetration depth as indicated elsewhere in this Section.
Repairs to the Boat Ramps 02464-5 VINYL SHEET PILING Sandy Point State Park Anne Arundel County, MD P-021-102-010 a. Maintain driving hammers in proper alignment during driving operations by use of leads or guides attached to the hammer. Caution shall be taken in the sustained use of vibratory hammers when a hard driving condition is encountered to avoid interlock-melt or damages. Discontinue the use of vibratory hammers and impact hammers employed when the penetration rate due to vibratory loading is one foot or less per minute.
b. Employ a protecting cap in driving when using impact hammers to prevent damage to the tops of piles. Remove and replace piles damaged during driving or driven out of interlock at the Contractor's expense.
c. Drive piles with the aid of a water jet when necessary.
d. Take adequate precautions to ensure that piles are driven plumb. If at any time the forward or leading edge of the pile wall is found to be out-of-plumb in the plane of the wall the pile being driven shall be driven to the required depth and tapered piles shall be provided and driven to interlock with the out-of-plumb leading edge or other approved corrective measures shall be taken to insure the plumbness of succeeding piles. The maximum permissible taper for any tapered pile shall be 1/8 inch per foot of length.
e. Piles in each run or continuous length of pile wall shall be driven alternately in increments of depth to the required depth or elevation. No pile shall be driven to a lower elevation than those behind it in the same run except when the piles behind it cannot be driven deeper. Incrementally sequence driving of individual piles such that the tip of any sheet pile shall not be more than 4 feet below that of any adjacent sheet pile. When the penetration resistance exceeds five blows per inch, the tip of any sheet pile shall not be more than 2 feet below any adjacent sheet pile. If the pile next to the one being driven tends to follow below final elevation it may be pinned to the next adjacent pile.
f. If obstructions restrict driving a pile to the specified penetration, the obstructions shall be removed or penetrated. If the Contractor demonstrates that removal or penetration is impractical, make changes in the design alignment of the pile structure as directed to ensure the adequacy and stability of the structure. Piles shall be driven to depths shown and shall extend up to the elevation indicated for the top of piles. A tolerance of 2 inches above the indicated top elevation will be permitted.
3. Do not drive piles within 30 feet of cast-in-place concrete, which has been in place for less than 72 hours.
Repairs to the Boat Ramps 02464-6 VINYL SHEET PILING Sandy Point State Park Anne Arundel County, MD P-021-102-010 4. Do not place cast-in-place concrete while pile driving operations are being carried out within a 30 foot distance
E. Cutting-Off and Splicing
1. Piles driven to refusal or to the point where additional penetration cannot be attained and are extending above the required top elevation in excess of the specified tolerance shall be cut off to the required elevation. Piles driven below the required top elevation and piles damaged by driving and cut off to permit further driving shall be extended as required to reach the top elevation at no additional cost to the Owner.
F. Inspection of Driven Piles
1. Perform continuous inspection during pile driving. Inspect all piles for compliance with tolerance requirements. Bring any unusual problems which may occur to the attention of the Engineer. Inspect the interlocked joints of driven piles extending above ground. Piles found to be out of interlock shall be removed and replaced at the Contractor's expense.
G. Pulling and Redriving
1. Pull, as directed, selected piles after driving to determine the condition of the underground portions of piles. Any pile so pulled and found to be damaged, to the extent that its usefulness in the structure is impaired, shall be removed and replaced at the Contractor's expense. Piles pulled and found to be in satisfactory condition shall be redriven when directed.

The goal of the project is to install new sheeting at the outboard end of the concrete boat ramps and fill any voids underneath the ramp with suitable material. In addition, the sheeting will be reinforced with additional protection to prevent future scouring. Construction will be separated into two phases to maintain public access to the boat ramps at all times. Although no as-built records of the existing boat ramps are available, DNR has provided the original design drawing of the boat ramps, a topographic survey of the existing facilities and a diver investigation r port. The project location is noted on the attached USGS 7.5 Minute Quadrangle (Gibson Island (MD)). Federal and/or State involvement for this project is Federal USACE Section 404 CWA permitting. No readily visible histOric structures, ruins or other cultural resources are identified in the project area. The project location is noted on the attached USGS 7.5 Minute Quadrangle (Germantown (MD)). Past land use at the project site is state park. Current land use is state park. No impacts are anticipated outside of the limits of disturbance (LOD). As required by the State/Federal involvement, we are requesting any information or records regarding the presence of culturat archaeological, or historic resources within the project area.

Driller’s Logs C. Laboratory Results MARYLAND DEPARTMENT OF NATURAL RESOURCES SANDY POINT STATE PARK BOAT RAMPS GEOTECHNICAL REPORT I. INTRODUCTION Sandy Point State Park Boat ramp provides boat access to the Chesapeake Bay from Sandy Point State Park. Twenty-two ramps provide boaters a safe place to launch and the ramps are very well used during boating season. The ramps are concrete with timber sheet piling at the toe. The soil at the toe is scouring causing the sheet piling to be exposed. Portions of the sheet piling have gone missing and voids are forming in the soil under the ramp. The ramps were constructed in 1970s, according to design drawings provided by the Maryland Department of Natural Resources (DNR). A soils investigation was conducted during September 2010 to ascertain the subsurface conditions at the project site. Geomatrix Drilling, Inc. of Baltimore, MD drilled and sampled five (5) borings under the supervision of Whitman, Requardt & Associates, LLP. Soil samples were tested for moisture content, gradation, and Atterberg limits. Testing was conducted by O’Berry Engineering, Inc of Edgewater, Maryland. Three soil samples were taking in addition to the SPT samples and were tested for BTEX and Total Petroleum Hydrocarbons by Microbac Laboratories, Inc of Baltimore, Maryland. II. GEOLOGIC SETTING The project site is located within the Alluvium interbedded sand, silt-clay, and subordinate gravel as defined by the “Geologic Map of Anne Arundel County”, by John D. Glaser published in 1976 by the State of Maryland, Department of Natural Resources, Maryland Geological Survey. III. SUBSURFACE INVESTIGATION All of the borings, labeled SP-1 through SP-5, were located on site at the end of the concrete boat ramp with the drilling barge anchored to the nearest pier. All borings were drilled using 6-inch diameter hollow stem augers. Samples were taken and standard penetration tests were performed using a 2-inch O.D. split spoon sampler driven by a 140-pound hammer falling freely for 30 inches. Blow counts were recorded for each 6-inch increment for a total penetration of 18 inches. For each boring samples were taken starting at the pond bottom and occurring at 5 foot intervals to a total depth of 30 feet from the pond surface. N:\42052-000\Engineering\Design\Geotechnical Report 1 Water level readings were not taken due to the borings being drilled beneath the pond surface. The depth to the pond bottom varied throughout the day as the tide changed. Tides change based on season as well as time of day. The Boring Location Plan, copies of the Driller’s Boring Logs, and Laboratory Test Results are included in the Appendix. Representative soils were classified and laboratory tested for Gradation Analysis, Atterberg Limits, Natural Moisture Content, BTEX and Total Petroleum Hydrocarbons (TPH). The results of the laboratory tests identified the soil according to the Unified Soil Classification System (USCS) and the Plasticity Index (PI). The PI is the Liquid Limit (LL) minus the Plastic Limit (PL) as shown in the laboratory results. IV. DISCUSSION OF SUBSURFACE CONDITIONS All borings encountered 8 to 9 feet of oligohaline brackish water from the Chesapeake Bay. The difference in depths can be accounted for by the changing tides. Borings SP-1 and SP-5 encountered very soft, 0 blows per foot (bpf), organic silt as the top most submerged soil layer. The organic layer had an average thickness of 18 inches. Below the organic silt lay 10 bpf silt and clay. The blows per foot increased with depth before both borings ended at 30 feet below the water level in 15 to 22 bpf material. Boring SP-1 had a final layer, 3.5 feet thick, of organic silt while boring SP-5 remained silt and clay. Borings SP-2 and SP-3 encountered approximately 18 inches of very soft, 0 bpf, organic silt as the top most submerged soil layer. Below the organic silt lay approximately 15 feet of 2 to 12 bpf sand with clay. The last layer was 4 to 6 feet of organic clayey silt having an average of 13 bpf. Boring SP-4 encountered four feet of very loose, 4 bpf, sand as the top most submerged soil layer. Below the sand lay 18 feet of 3 to 15 bpf sandy clay. The blows per foot increased with depth and this boring appeared to have only two layers. Organic soil was present at the top of the submerged soils but in a thin layer that was taken for BTEX and TPH laboratory testing and did not show up in the first SPT sample. BTEX and TPH testing showed contaminates were not detected at or above the reporting limit. Full results of these tests are included in the appendix. Natural Moisture Content and Atterberg Limit tests were performed on selected samples. The results of these tests are summarized as follows: N:\42052-000\Engineering\Design\Geotechnical Report 2 Boring No. Sample No. Sample Depth Natural PL LL PI Moisture (%) SP-1 S-2 13.5’ - 15’ -- 19 32 13 S-3 18.5’ - 20’ 52.3 ------S-5 28.5’ – 30’ 50.6 ------SP-2 S-2 13.5’ - 15’ 22.6 ------S-4 23.5’ – 25’ -- 43 88 45 SP-3 S-2 13.5’ - 15’ 23.7 ------S-3 18.5’ – 20’ ------S-5 28.5’ – 30’ 66 54 97 43 SP-4 S-2 13.5’ – 15’ ------S-3 18.5’ – 20’ -- 31 71 40 S-4 23.5’ – 25’ 46.8 ------SP-5 S-2 13.5’ – 15’ 24.1 ------S-3 18.5’ - 20’ ------S-4 23.5’ – 25’ -- 37 74 37 V. SHEET PILING CONSIDERATIONS Several options are available for replacing the failing sheet piling wall at the end of the boat ramp. The first is flat panel vinyl sheet piling, the second is z-shaped vinyl sheet piling and the last is z-shaped steel sheet piling. The sheet piling was designed to withstand scour up to 6 feet deep, based on the dive report from the DNR, be subjected to loading from trucks with boats on trailers and be capped with concrete. It will be installed as close as possible to the existing sheet piling and backfilled with sand. A flat panel vinyl sheeting section was requested in the project design program and the Flat Panel from Crane Materials International was selected for analysis. Using a sheet pile embedment depth of 12 feet and a design moment of 4796 ft-lbs the deflection was 3.45 inches. A z-shaped vinyl sheeting section was analyzed to minimize the deflection. SG-650 from Crane Materials International was analyzed. Using a sheet pile embedment depth of 12 feet and a design moment of 4796 ft-lbs the deflection was 2.14 inches. A z-shaped steel sheeting section was analyzed as a standard material choice. PZC 13 was analyzed. Using a sheet pile embedment depth of 12 feet and a design moment of 4796 ft-lbs the deflection was 2.09 inches. The cost per square foot of vinyl sheet piling is lower than that of steel sheet piling. The deflections generated are reflection of 6 feet of scour; in reality the scour considerations should limit scour to near zero feet thus making deflection a mute point. The flat panel vinyl sheeting requested by the MD DNR is recommended. N:\42052-000\Engineering\Design\Geotechnical Report 3 The following soil parameters were used in the above sheet piling analyses: Buoyant unit weight of soil ' = 70 pcf Angle of Soil Incline = 6.8° Angle of Internal Friction = 25° Active Pressure Coefficient ka = 0.4 Passive Pressure Coefficient kp = 2.5 VI. VOID & SCOUR CONSIDERATIONS Missing timber sheet piling has caused scour beneath the concrete boat ramp. To fill these voids grout will be pumped underneath the boat ramp behind temporary forms. Open graded coarse aggregate will be used to fill the void between the existing sheet piling and the new sheet piling. The client suggested #2 stone to a depth of 1 foot below the mudline. WR&A determined that #2 stone would be too lightweight to counter scour. A nonwoven geotextile to reduce sinking and 18 inches (minimum) of Class 1 rip rap is proposed instead.

ANDY HANAS MARYLAND DEPARTMENT OF NATURAL RESOURCES ENGINEERING AND CONSTRUCTION FROM: . RANDYWITTE.....::-f-- SUBJECT: RESULTS OF SUBAQUATIC SURVEY OF SANDY POINT STATE PARK BOAT RAMPS DATE: APRIL 10, 2007 CC: FILE ·- ----..---· ·--·----··..-----'--:· Pursuant to our agteetnenon April 5, 2007, I conducted a sub-aquatic survey of the boat ramp area at Sandy Point State Park. This survey was conducted in response to a teport from the Anne Arundel County Fire Department Dive Tenm (AADT) indicating that there were large pieces of concrete and large .rocks on or around several of the boa1 ramps. Dw:.ing my survey, T only located two possible hazards to navigation. lhese hazards were crab pots, which l removed from the water. 1 located several piles of broken concrete, in the areas indicated by the AADT, but none of these piles extended mote than n few inches above the surrounding bottom. As such, I do not believe them to be a hazard to tuvigation. In the locations where MDT indicated there wete pieces of com.:tet:e sticking out of the sllttOunding bottom, I located the concrete ••kicker" at the end of boat .tamp #21. At the location where n large rmk was reported to be, Ifound only the end of thtboat ramp (#20). However, the pond bottom nt the end of the ramp app!.".ars to have washed away, and the end of the ramp extends two to three feet above the bottom. Because of the scouring, and the murky conditions, the ends of the tamps could have been mistaken fur la.tge .rocks or pieces of concrete. I also observed some undercutting of the ends of the several boat ramps, and decided to survey all cif the ramp ends to detetmi11e the conditions. Wood "V" groove sheeting, dtiven .into the pond bottom, originally protected the ends of the mmps. ln many areas, this sheeting has been broken off at pushed away from the end oftht! ramp. In areas where this sheeting is missing, the pond bottom has washed from under the concrete i:amp as far back as 6'. The concrete ramps appear to be about 8' thick, with a kicker about (/' high. Below is a chart with a description of whnl I observed at the end of each .ramp. . •, RAM1.J# DESCRIPTION OF CONDITION 1 The end nf the ramp is covered in silt, up to the kicker. ..,- 2 Oniy a few of the V groove boards are missing.
