REQUESTED ACTION

Approve Daniel W. Ayer Revocable Trust's request to perform the following work on Cocheco River in Dover. File tf2018-00515. This project will not have significant impact on or adversely affect the values of Cocheco River.

An amendment request was received by NHDES, dated November 26, 2018, to change the size, location and

configuration of the originally approved tidal docking structure, in order to meet the requirements outlined by the USArmy Corps of Engineers. The New Hampshire Department of Environmental Services (NHDES) has reviewed andapproved the above referenced application to amend NHDES Permit 2018-00515 to impact 984 square feet of tidalwetland to replace an existing tidal docking structure. The new structure will be constructed from an existing 4 foot x 4foot landing and stairs (located landward of the highest observable tide line) and consist of a 3 foot x 32 foot rampconnected to a 10 foot x 12 foot seasonal landing float connected to six 8 foot x 16 foot seasonal floats configuredparallel to the river channel. The overall structure length seaward of the highest observable tide line is 40 feet, providingeight slips on 502.5 feet of frontage on the Cocheco River.

The New Hampshire Department of Environmental Services (NHDES) imposed the following conditions as part of thisapproval:

1. AMENDED: All work shall be in accordance with plans by MJS Engineering dated January 31, 2018, and revised

through October 04, 2018, last received by the NHDES on November 26, 2018.2. No less than 5 state business days prior to starting work authorized by this permit, the permittee shall notify the

NHDES Wetlands Bureau Pease office and the local conservation commission in writing of the date on which work

under this permit is expected to start.

3. AMENDED: This amended permit shall not be effective until recorded at the Strafford County Registry of Deeds

office by the permittee. A copy of the recorded permit shall be submitted to the NHDES Wetlands Bureau prior to

construction.

4. Any future work in jurisdiction as specified in RSA 482-A on this property will require a new application andapproval by the NHDES Wetlands Bureau.

5. No person undertaking any activity shall cause or contribute to, or allow the activity to cause or contribute to, anyviolations of the surface water quality standards In RSA 485-A and New Hampshire Administrative Rule Env-Wq

1700.

6. AMENDED: This tidal docking structure constructed from an existing 4 foot x 4 foot landing and stairs (locatedlandward of the highest observable tide line) and consisting of a 3 foot x 32 foot ramp, a 10 foot x 12 foot seasonallanding float and six 8 foot x 16 foot seasonal floats configured parallel to the river channel with an overall

structure length seaward of the highest observable tide line of 40 feet, providing eight slips on 502.5 feet offrontage on the Cocheco River, shall be the only docking structure on this water frontage.

7. There shall be no removal of mature trees along the shoreline of the river on this property associated with the

construction of the dock and access way.

8. Construction of the dock shall occur from a barge equipped with a crane, at low tide, to reduce potential impacts to

the river bank and the estuarine intertidal and subtidal wetlands.

9. Decking shall have at least 3/4-inch spacing between the decking planks to provide sufficient sunlight penetrationand rainfall to underlying vegetation.

10. Appropriate siltation/erosion/turbidity controls shall be in place prior to construction, shall be maintained duringconstruction, and shall remain in place until the area is stabilized.

11. Work shall be conducted in a manner so as to minimize turbidity and sedimentation to surface waters and

wetlands.

12. Work shall be conducted in a manner that avoids excessive discharges of sediments to fish spawning areas.

13. The seasonal structures, including but not limited to the gangway and float, shall be removed during the non-

boating season and stored on the existing pier or in an upland location.

14. All construction-related debris shall be properly disposed of outside of the areas subject to RSA 482-A.

15. Within three days of final grading or temporary suspension of work in an area that is in or adjacent to wetlands or

surface waters, all exposed soil areas shall be stabilized by seeding and mulching during the growing season, or if

not within the growing season, by mulching with tack or netting and pinning on slopes steeper than 3:1.?

EXPLANATION

The NHDES approved this project on January 8, 2019. The NHDES supported its decision with the following findings:I

1. This is a Major Project per New Hampshire Administrative Rule Env-Wt 303.02(a), projects in sand dunes, tidal

wetlands, or bogs, except for the repair of existing structures pursuant to New Hampshire Administrative Rule Env-

Wt 303.04(v).

2. The applicant has provided evidence which demonstrates that this proposal is the alternative with the least adverse

impact to areas and environments under the department's jurisdiction per New Hampshire Administrative Rule

Env-Wt 302.03.

3. The original parcel, including approximately 42 acres with approximately 2,500 feet of water frontage on the

Cocheco River, was subdivided into an open-space subdivision plus a 13 acre conservation parcel with 1,400 feet of

water frontage now held by New Hampshire Fish and Game. The remainder of the subdivision (approximately 29

acres with 1,055 feet of water frontage) is dedicated as open-space waterfront parcels, including the proposedtidal docking structure, shared by residents of the inland portion of the subdivision.

4. Pursuant to New Hampshire Administrative Rule Env-Wt 204.05, in correspondence dated February 17, 2018, the

applicant requested a waiver to New Hampshire Administrative Rule Env-Wt 402.21, Modification of Existing

Structures. The existing tidal docking structure on the subject frontage (depicted as "Pier #2" on the approved plan

set) was permitted by the NHDES Wetlands permit #2003-02241.

5. In accordance with New Hampshire Administrative Rule Env-Wt 402.14, Exceptions to Frontage Criteria, the

proposed structure will accommodate eight boat slips on 502.5 feet of water frontage, which would otherwise

typically qualify for only seven boat slips.

6. A conventional subdivision on this property could have yielded eight waterfront lots, each presumably eligible for

individual tidal docking structures and each with multiple slips. Alternatively, the primary lot was subdivided in such

a way as to conserve the natural waterfront, reduce the potential number of structures and slips on this reach of

the Cocheco River, and reduce the overall environmental impact.

7. In accordance with New Hampshire Administrative Rule Env-Wt 204.04, a waiver will be granted if the project will

not have an adverse impact to the environment or natural resources of the state, public health, or public safety,

and the strict compliance with the rule will provide no benefit to the public and will cause an operation or

economic hardship to the applicant.

8. Consistent with New Hampshire Administrative Rule Env-Wt 204.04, the Department finds that the alternative

configuration proposed will minimize adverse environmental impact to the surface water and shoreline and,

therefore, waives the standard configuration requirements set forth by New Hampshire Administrative Rules Env-

Wt 402.13 and 402.21.

His Excellency, Governor Christopher T. Sununu

and The Honorable Council

9. The dock is the minimum length necessary to provide full tide access at this location and to a water depth whichwill prevent the float and vessel from sitting on the mud at low tide.

10. The decking of the dock will have a minimum of have 3/4-inch spacing between the decking planks. Further, theapplicant will be utilizing a barge and crane to complete construction of the dock from the water to minimize

impacts to the wetland resource.

11. The applicant has demonstrated by plan and example that each factor listed In New Hampshire Administrative RuleEnv-Wt 302.04(a) and (c). Requirements for Application Evaluation, has been considered in the design of theproject. I

12. NH Natural Heritage Bureau (NHB) has record of a sensitive species and an exemplary natural community withinthe vicinity of the project (NHB18-0468).

13. In correspondence dated February 13, 2018, NHB stated that the project is not expected to adversely impact thesensitive species or the exemplary natural community.

14. In correspondence dated February 08, 2018, the US Fish and Wildlife Service (iPaC Consultation Code: OSEINEOO-

2018-SLI-0941) identified the Northern Long Eared Bat and Small Whorled Pogonia, both federally threatened, tobe within the vicinity of the project.

15. On June 19 2018, the results of the NHDES staff field inspection found that the site is accurately represented in theapplication.

16. In accordance with RSA 482-A:8, NHDES finds that the requirements for a public hearing do not apply as thepermitted project is not of substantial public interest, and will not have a significant impact on or adversely affectthe values of the estuarine resource, as identified under RSA 482-A:l.

17. In correspondence dated June 21, 2018, the Pease Development Authority, Division of Ports and Harbors,

determined that the project would have no negative effect on navigation in the channel.

18. In correspondence dated March 23, 2018, the Dover Conservation Commission stated no opposition to the projectas proposed.

19. In correspondence dated February 22, 2018, signed authorization was provided by the applicant to allow theiragent to act on their behalf throughout the permitting process.

20. No comments of concern were received by the NHDES from local governing organizations.21. In correspondence dated November 26, 2018, an amendment request was received by NHDES to change the size,

location and configuration of the originally approved tidal docking structure, in order to meet the requirementsoutlined by the US Army Corps of Engineers (subsequent to NHDES' original approval).

22. The float, as amended, will have 4-6 inches of vertical clearance at low tide between the main float and the surface

of the substrate. The substrate in this location consists of 3-4 inches of silt above ledge.23. In correspondence dated December 13, 2018, the applicant's agent stated that it is not possible to install piles for

float stops in this location, due to shallow depth to ledge, precluding minimum vertical clearance criteria of 18inches per the National Marine Fisheries Service.

24. In accordance with RSA 482-A:3 XIV (e), the proposal does not represent a significant amendment and is notexpected to have an adverse impact on the environment, it is therefore approved.

Application file documents are being forwarded to the Governor and the Executive Council in connection with their

consideration of this matter pursuant to RSA 482-A:3,ll.(a) as it is a major project in public waters of the state.

We respectfully submit this request for your consideration.

Detailed Description: 2004: Dominant species are Spartina alterniflora (smooth cord-grass), Amaranthuscannabinus (water hemp), and Typha angustifolia (narrow-leaved cattail). Less frequent areLemna minor (lesser duckweed), Polygonum hydropiper (water-pepper), Argentina egedii(coastal silverweed), Eleocharis parvula (small spike-rush). Ranunculus cymbalaria (seasidecrowfoot), Liiaeopsis chinensis (eastern lilaeopsis), and Samolus parvijlorus (false waterpimpernel). 1988: Forms a narrow zone along the river, dominated by Spartina alternijlora(smooth cord-grass). A few stands of Typha angustifolia (narrow-leaved cattail) exist,mostly less than an acre in size. Rare plant species present are Samolus parvijlorus (falsewater pimpernel), Lilaeopsis chinensis (eastem lilaeopsis), and Eleocharis parvula (smallspike-rush). Spartina alterniflora (smooth cord-grass) is dominant. A few stands of Typhaangustifolia (narrow-leaved cat-tail) exist. Many exotic species are present. The bases ofsteep, rocky slopes support virtually no emergent vegetation.

General Area: 2004: This low marsh lies adjacent to a sparsely or narrowly vegetated high brackish tidalriverbank marsh. The high tidal riverbank is often an unvegetated zone grading into theadjacent upland. Some characteristic species are Solidago sempervirens (seaside goldenrod)and Spartina pectinata (fresh-water cord-grass). Along most of the riverbank community,moderate residential and commercial development occurs on adjacent lands. High levels ofdevelopment occur along the west end of the riverbank in downtown Dover. 1988; A narrowzone along the river. Bordered by steep forested slopes and heavily impacted areas.

General Comments:

ManagementComments:

2004: Several invasive species occur on the higher margins of the riverbank community,especially at the west end nearest downtown Dover. They include Lythrum salicaria (purpleloosestrife), Phalaris arundinacea (reed canary-grass), Rorippa nasturtium-aquaticum (truewatercress), Polygonum cuspidatum (Japanese knotweed), and Solanum dulcamara(nightshade). These plants should be monitored. 1988; Guard against future development.Current disturbance includes impacts by rock fill, dams, clearing, and power plantconstruction.
