In conjunction with the preliminary plan requirements of Chapter 123, Subdivision and Land Development, the following existing site features shall be designated on a conservation plan, drawn at the same scale as that required for preliminary plans:
A.
Tract boundaries, with suitable metes and bounds.
B.
Topography or degree of slope, as measured at two-foot contour intervals in ranges of 0% to 15% and 15% to 25%, and as measured at five-foot contour intervals for slopes exceeding 25%. At the discretion of the Township Planning Commission and upon the recommendation of the Township Engineer, the topography of adjacent lands within 200 feet of the tract shall be shown with permission of the adjacent landowner. Location and elevation to which contour elevations refer shall be identified; where reasonably feasible, this shall be a known, established benchmark as approved by the Township Engineer. At the discretion of the Township Planning Commission and upon recommendation of the Township Engineer, United States Geological Survey contours will be acceptable for such purposes where it is determined that field run topography is not required.
C.
All existing woodland or tree masses, species and size of trees over six inches diameter not part of a tree mass, quarries, rock outcroppings or other geological formations, ponds, streams and other bodies of water, springs, marshes, other areas subject to inundation and any other significant features within the property and, with permission of the adjacent landowner, within 50 feet of its boundaries. Driplines for tree masses shall be shown on the plan. Where floodplain areas, as defined in Article VI, FPC Floodplain Conservation District, are located on the tract, such area(s) shall be delineated on the conservation plan.
[Amended 6-25-2001 by Ord. No. 4-2001]
D.
Locations and boundaries of all soil types, with an identification key.
E.
A description of each soil type which explains limitations for on-site sewage disposal and includes the location and results of any soil percolation tests (if on-site sewage disposal is proposed which would require such tests).
F.
Notations indicating:
(1)
All trees or portions of tree masses or woodland proposed to be cleared as part of the proposed subdivision or land development plan, together with the reasons for such clearing;
[Amended 6-25-2001 by Ord. No. 4-2001]
(2)
All proposed alteration of the natural grade, whether by cut or by fill, exceeding two feet, together with reasons for such alteration.
G.
Locations of all historic resources or structures on the tract or on any abutting property.
H.
Wetlands.
(1)
Wetlands shall be designated on said plan where indicated by any one or more of the following:
(a)
The National Wetlands Inventory Maps, as prepared by the United States Fish and Wildlife Service or any other governmental agency having jurisdiction;
(b)
Hydric soils or soils with hydric soil inclusions, as depicted in the soil survey of Chester and Delaware Counties and/or in United States Department of Agriculture Soil Conservation Service Hydric Soils Lists; and
(c)
The existence of hydrophytic vegetation or hydrologic conditions, as determined by on-site investigations performed in accordance with the Federal Manual for Identifying and Delineating Jurisdictional Wetlands, dated January 10, 1989, or as later amended.
(2)
If, after examination of the site, a qualified professional selected by the applicant determines that wetlands are not located on the site, the following note must appear on the plan.
"This site has been examined by a qualified professional and no wetlands were found to exist." |
(3)
Submissions containing this note must be accompanied by a written statement signed by the examining professional attesting to the fact that the site was examined in accordance with the Federal Manual for Identifying and Delineating Jurisdictional Wetlands, dated January 10, 1989, or as later amended, and no wetlands were found to exist. In addition, a written statement of the qualifications of the professional who examined the site shall accompany the submission.
