075WL_*.dgn July 2015

Section 075WL has been created for wetlands, mitigation and other environmental issues. This section shall be included on all projects where wetlands have been delineated. This section may be required even if there are no designed wetland impacts. This section is also intended to help communicate the avoidance of wetland impacts. This section is usually not required on projects that don’t require a wetland review for environmental clearance. Contact the Environmental Section Leader if project circumstances are questionable. Ensure the appropriate reference files are attached and displayed. See “Appendix A – Plan Sheet References” (http://www.dot.nd.gov/manuals/design/caddmanual/appendixa.pdf#page=11). Additional drawing references may be required if a project includes temporary work such as bypasses or cofferdams. Drawings showing temporary earthwork should be displayed in the 075WL sheets even if it doesn’t create impacts. All information in the Wetland_Impacts.dgn should be display in the 075WL sheets. This includes:

• Delineated wetlands and other waters • Hatching for both temporary and permanent wetland impacts • Hatching for both temporary and permanent other water impacts • Hatching for wetland mitigation • Labels

o Type of impacts and mitigation o Acreages and/or linear feet of impacts and mitigation o Wetland numbers

• Grading tie lines. The control.dgn reference should display the following information at a minimum.

076TE_*.dgn July 2015

Section 076TE is used for Temporary Sediment and Erosion Control. These sheets are used in storm water pollution prevention plan (SWPPP) evaluations. This guidance addresses some of the information requirements for SWPPP sheets. Ensure the appropriate reference files are attached and displayed. See “Appendix A – Plan Sheet References” (http://www.dot.nd.gov/manuals/design/caddmanual/appendixa.pdf#page=11). All information in the T_Erosion_C.dgn should be display in the 076TE sheets. The Wetland_Impacts.dgn reference display within the 076TE sheets requires level display adjustments. The exterior boundaries for all water bodies including delineated wetlands and wetland mitigation needs to be displayed, but all hatching levels within this reference need to be turned off. Most labels should also be turned off. The only labels from this reference that should be displayed in 076TE sheets are for “Grading Tie Lines”. The DS_Util.dgn reference display within the 076TE sheets requires level display Adjustments. Proposed pipes and culverts are not shown in these sheets. The only thing from DS_Util.dgn that is displayed in these sheets is the flow lines. If temporary drainage patterns are different than the final drainage patterns, DS_Util.dgn doesn’t need to be displayed and the temporary flow lines from T_Erosion_C.dgn will be displayed. The following are some other import referenced features. This list is not inclusive. The control.dgn reference should display the following information at a minimum.

Design.dgn Aug 2014

Safety fence is used to protect cultural resources avoidance areas within an earthwork project. These areas should be marked with the cultural resource avoidance hatching. The only time safety fence should be drawn in design.dgn is when it is used to mark cultural resource avoidance areas. Safety fence used for normal purposes should be drawn in a consign.dgn The outline of new bridges and box culverts should be drawn in the design.dgn with the “bridge-box culvert” line. Bridge design plan sheets are seldom drawn so that they can be geo-referenced. Designers may have to adjust referencing to trace – draw the bridge or box culvert outline. In some cases, the outline may have to be drawn from scratch by using the bridge drawing details.

Appendix-Q

DS_Util.dgn (Draft Revision) Dec 2016

The DS_Util drawing shall include both 2D and 3D Models. An OpenRoads managed – civilized “Default–3D” model is recommended but is not mandatory. The managed – civilized 3D model is automatically created from within the 2D model by creating a civilized 3D feature or setting an active terrain. Presently, the most important reason for a 3D drainage model is to support OpenRoads cross sections. If drainage items need to be shown in cross sections they should be drawn in the 3D model. The 2D model should include the annotation, dimensions and other items not shown in the cross sections. Flow lines should also be shown in the 2D model. All ditches must be marked with flow lines to indicate direction of flow. The 3D model should include the pipes and structures. Structures can be modeled with a basic slabs or cylinders or both. The NDDOT 3D structures library is incomplete. The NDDOT has not implemented the 3D features of Bentley – Subsurface Utility Design and Analysis. A Macro has been devolved to help draw 3D pipe. The macro uses a 3D line as a reference. The 3D lines should be drawn from pipe invert to invert. The macro will use this line to place pipe and end sections. The macro can be accessed from them main pull down menu, “NDDOT > Tools > Pipe 3D by Line”. This tool is only accessible from a 3D model. A named expression is used to hide the tool in the menu when a non-applicable 2D model is open. The following dialog box should open when the tool is accessed. Select the type of pipe, size, and end sections. Then click the “Place Pipe” button and select a 3D line. The macro will place the 3D pipe. The 3D elements are place as cells. One more adjustments needs to be made before these elements are ready for plan production.

Environmental_Wetlands.dgn –Base Maps July 2013

The MicroStation base maps have been updated to work with annotation scale and geographic coordinate systems (GCS). The NDDOT wetland database is maintained with ESRI (ArcMap) and it is exported to the following MicroStation wetland drawing by the environmental section. R:\project\BaseMaps\Projected Coordinate Systems\Environmental_Wetlands.dgn Designers should reference this drawing using the GCS tools within MicroStation. The appropriate project wetlands should be copied into the designer’s wetland drawing (Wetland_Impacts.dgn). See Also Wetland_Impact guidance. http://www.dot.nd.gov/manuals/design/caddmanual/AppendixQ/Wetland_Impacts_dgn.pdf The drawings in the “base map” directory change over time because additional wetland delineation information is added for new projects. Project drawings should not be edited after they are signed and sealed even if the changes are not within the viewable limits. Copying wetlands to project files preserves a static copy. Creating a copy of the wetlands for designers can also expedite and simplify plan production work. Information that is a considerable distance from the project limits can be deleted (Example you might not need delineation information on Hwy 281 if you are working on Hwy 20). Cross sections can be processed quicker if Geopak doesn’t have to read about wetlands that are not directly related to the project limits. As designers copy wetland information, they need to assure the copy will be updated if updates occur in the original map and are within their project limits.

Appendix-Q

P_Erosion_C.dgn April ‘17

Permanent seeding and wetland seeding are included in the P_Erosion_C.dgn. Seeding often extends beyond the Grading Tie Line for a better vegetation transition. On site wetland mitigation may require special wetland seeding. There is a separate wetland seeding line and shading that should be used in the P_Erosion_C.dgn. Other temporary seeding should be included in T_Erosion_C. Final wetland shapes should be included in the P_Erosion_C.dgn. These shapes should be similar to the delineated wetlands shown in the Wetland_Impacts.dgn except with the permanently impacted areas trimmed off. The shapes should represent what the delineated wetlands will look like after construction. Mitigation areas should not be represented in these shapes. Wetland mitigation areas will be shown separately in other drawings. The following is a recommend procedure for including the final wetland shapes in the P_Erosion_C.dgn:

1. Copy elements on both “Wetland Delineated Line Exist” and “Wetland Impact Permanent Hatch” levels into the P_Erosion_C.dgn. Do NOT copy “Wetland Impact Temporary Hatch” or “Wetland Creation Mitigation Pattern” levels.

2. The “Create Region” tool will use the active symbology. Maintain the appropriate US ACE Jurisdiction Color Indicator even though they will not be labeled. Set the active symbology to the applicable wetland;

a. Existing Wetland Jurisdictional b. Existing Wetland Non-Jurisdictional c. Existing Wetland Undefined Jurisdiction

3. Use the “Create Region” with the difference option to trim the “Wetland Impact Permanent Hatch” areas from the “Wetland Delineated Line Exist” Elements. If the “Keep Original” option is turned off, the “Wetland Impact Permanent Hatch” element will disappear when using the create region tool.

4. While using the CADD Standards and these recommended procedures, there should be no wetland hatching or wetland patterning in this final drawing.

Appendix-Q

T_Erosion_C.dgn Aug 2014

If temporary drainage patterns are different than proposed, the temporary drainage patterns must be marked with flow lines within the T_Erosion_C.dgn. Indicate flow direction for all ditches and areas where appreciable flows enter or leave the DOT right of way.

CADD Standards

Appendix-Q

Wetland_Impacts.dgn April ’17, wetland seeding discussion moved to P_Erosion_C.dgn

The wetlands associated with a project shall be copied from the Environmental_Wetlands drawing into the Wetland_Impacts.dgn. The Designer is responsible for confirming with the ETS Division that copied information is current and appropriate for calculating impacts. The delineations in the base maps are occasionally updated. Some projects may have future delineation updates that should be used for your project. Designers should NOT assume the delineations are applicable just because they can reference and copy wetlands. Coordination between Design and ETS is always needed. Consultants need to create a drawing named Environmental_Wetlands.dgn in order to access the Environmental task group. The wetlands are drawn in Environmental Wetlands drawing and then copied into the Wetland Impacts drawing. This step may not be intuitive, but it is based on separate NDDOT division and functions. Delineated wetlands are symbolized 3 different ways; Existing Wetland Jurisdictional, Existing Wetland Non-Jurisdictional, Existing Wetland Undefined Jurisdiction. The wetland symbology should indicate US Army Corp of Engineers Jurisdiction when known. Standard symbology settings for the Wetland_Impacts.dgn are found in the MicroStation task group named “Wetland_Impacts”. The Wetland_Impacts drawing should indicate the “Grading Tie Line”. Geopak sometimes refers to this line as “Limits of Construction”. However the term “Limits of Construction” should NOT be used in any drawing labels. These lines should always be labeled “Grading Tie Line” to disassociate it from areas of ground disturbance. The Grading Tie Line may also indicate the type of grading tie.

• Grading Tie Cut Line (Green Solid Line) • Grading Tie Fill Line (Red Dashed Line) • Grading Tie Transition Line (White Dotted Line)

If it is helpful to show cut, fill and transitions in a plan view, all three of these lines should be labeled. If showing all three of these lines would create confusion then all of the “Grading Tie Line” symbology can be shown as the white dotted line used for Grading Tie Transition Line. These lines must be clearly labeled in the Wetland_Impacts drawing in order to avoid confusion. The levels used for placing Grading Tie Line labels is important because this is the only label from the Wetland_Impacts drawing that will be displayed in the 076TE and 077PE sheets. Include the wetland numbers from the wetland impact table. Usually these labels are copied from the Environmental_Wetlands drawing. Use the “Wetland Impact Permanent” and “Wetland Impact Temporary” hatch tools to indicate permanent and temporary wetland impacts. Label impact acreage.

CADD Standards

Appendix-Q

The drawing element “Other Water Line” shall be used to delineate dry channels and deep water habitat (fill greater than 6.6 feet below existing water line). The patterning named “Other Water Permanent Impact” and “Other Water Temporary Impact” shall be used to indicate if these impacts are temporary or permanent. Label impact acreage. Use the “Wetland Mitigation Line” and “Wetland Mitigation Pattern” tools to indicate wetland mitigation if applicable. Create a contour line indicating the location and bottom elevation for the wetland mitigation area. Addition labeling and dimensioning may also be helpful. If wetland shapes are irregular use northing and easting’s to indicate important points. The plans need to provide enough details to correctly construct the mitigation areas. Label mitigation acreage. On site wetland mitigation usually requires additional plan preparation. The mitigation needs to be detailed on the cross section sheets. Additional cross sections may be needed (See Section 4.7.1 Cross Section Interval). If the mitigation wetlands have an irregular shape, additional information should also be included in the plans. See the “Wetland Information Check List” for additional Guidance. http://www.dot.nd.gov/manuals/design/designmanual/wordfiles_design/Wetland%20Information%20Guidance%20for%20NDDOT%20Designers.doc

Xsec.dgn July 2013

There are 3 different lines to represent “existing ground” in a cross section:

1. Exst Grnd (Existing Ground) 2. Exst Grnd Assumed (Existing Ground Assumed) 3. Exst Grnd Void (Existing Ground Void)

“Exst Grnd” is used in areas of reliable survey data. “Exst Grnd Assumed” is in areas of an obscured surface. The obscured areas are often represented with a separate dtm or tin. “Exst Grnd Assumed” should also be used in areas where designers make assumptions or guesses about the existing ground such as under water assumptions. “Exst Grnd Void” is for areas where there is no reliable survey data and no assumptions are being made. The Exst Grnd Void line is used just to provide a continuous surface. The following wetland information should be shown on proposed cross sections if applicable.

• Limits of delineated wetland • Limits of onsite mitigation area – Enough cross sections should be cut to clearly show

beginning and end of the area along with the elevation. For example cross sections should be cut near the beginning, center and near the end of each mitigation site.

• Included “Other Waters” line to distinguish limits of deep water areas (water deeper than 6.6’)

• Important mitigation elevations should be labeled. • If the mitigation wetlands have an irregular shape, additional information should also be i

ncluded in the plans.

Cross Sections and Utility Features April 4, 2017

Three different utility models are needed for utility conflict plans;

1. Topog_Drape.dgn – Topographical linear features 2. Xsec_Utility_Crossings – Manually drawn linear elements drawn in plan view. Begin

and ending crossing elements are drawn at approximate locations that will intersect known cross sections locations.

3. Xsec_Utility_Cells_as_Lines - Utility cell will be converted to 3D linear elements so that they can be displayed in cross sections.

All three of these models use OpenRoads technology where the 3D linear element can be represented by a MicroStation cell in the cross sections. Completed models can be referenced into any model used for cross sections and the utility cells will automatically be referenced into the cross sections. This guide will discuss how to prepare each of these 3 models, but before this is discussed, 3 task common to preparing all 3 models should be understood.

1. Create OpenRoads Features from plain MicroStation graphics 2. Set Active Terrain 3. Drape Features on Surface (Terrain).

Create OpenRoads Features from plain MicroStation graphics The “General Geometry > Feature Definition Toggle Bar” and “Set Feature Definition” tools can be used to assign a feature definition to plain MicroStation graphics. This process may be automated for many features that are referenced in cross sections by using a macro.

1. Features are typically created from a 2D model. This will allow for both a 2D and separate but linked 3D features. This facilitates easier feature editing. Having utility graphics in a 2D model with the correct level color style and weight attributes is a prerequisite.

2. Use the Macro to set the applicable feature definitions. This macro can take over a minute to process. The macro can be activated from the main menu: NDDOT > Tools > Utilities > Set Utility Features.

3. Use the Element Information tool to confirm that the feature definitions have been set.

CADD Standards

Appendix-Q

Set the Active Terrain Setting the active terrain provides a reference surface for draping features (assigning elevation based on surface). Setting the active terrain can also create a “Default-3D” model that is associated to the “Default” 2D model. These steps are needed for assigning elevations to different types of features and will be cross referenced in preparing the different utility reference drawings.

1. From a 2D model reference the 3D terrain from a terrain drawing. Utilities will usually be using a voidless terrain named Terrain_Exst_Drape.dgn.

2. Right click and press on the terrain boundary. A popup tool tray should appear. The second icon in the tray is used for setting the active terrain.

Drape Features on Surface (Terrain) The “Vertical Geometry > Profile from Surface” tool can be used to assign elevation information to a feature. “3D Linear” features in a 3D model will be created from 2D features in a 2D model.

1. Set the Active Terrain (see previous guidance). 2. Create OpenRoads features (see previous guidance). The features should be in a 2D

model. 3. Features are typically draped one of three different depths; 0’, -3’ or -7.5’. Load the

Utiltiy Level Filters to assist with level selection. This can be done from the main menu: NDDOT > Levels > Level Filters > Utilities.

4. All the features at a specific depth can be draped at one time. After the utilities of a specific depth are selected with the applicable filter, use the “Profile from Surface” tool to assign a profile based of the active terrain.

5. Repeat step 4 for each group of utilites at other depths. 6. After the utilities have been draped, “3D linear”

elements should have automatically been created in the 3D Model. Review the 3D model for these elements.

7. Set the “Drawing Scale” of the 3D model to the Display scale for the cross sections. This “Drawing Scale” setting will determine the size of the MicroStation utility cells displayed in the cross sections. “Save Settings” so that this Drawing Scale is kept.

General Utility Model Preparation The following information is required – as a starting point;

• Topog.dgn with utilities • Terrain_Exst_Drape.dgn with voidless terrain.

CADD Standards

Appendix-Q

Preparing Topog_Drape.dgn 1. Create a 2D drawing named Topog_Drape.dgn. 2. Attach the Utility Filters. This can be done from the main menu: NDDOT > Levels >

Level Filters > Utilities. 3. Reference the drawing Topog.dgn and display only utility lines by using the filter

“Utility_Lines”. 4. Copy these utility lines into this Topog_Drape.dgn. 5. “Create OpenRoads Features from plain MicroStation graphics” (see previous

instructions). 6. “Set the Active Terrain” (see previous instructions). 7. “Drape Features on Surface” (see previous instructions).

Preparing Xsec_Utility_Crossing Drawing In most cases crossing elements are not perfectly perpendicular to the alignment and would be difficult to reference into a true cross section. This process creates an embellished model that represents utility crossings on the nearest cross section.

1. Create a 2D model named Xsec_Utility_Crossings.dgn. 2. Identify your cross section range, interval and key stations. You can use the following

options to display OpenRoads Pattern Line for the cross sections to help sketch in crossings to pattern lines. Drawing Open Roads Pattern Lines is optional.

a. This part of the guide doesn’t address how to create cross sections sheets. Only certain cross section settings and files pertaining to pattern lines are discussed.

b. Try to get a *.xsc file from the designer. The cross section range, interval, and key station can be saved to this file. Using the same *.xsc file as the designer will help you draw crossing lines that will match the final plans.

c. Before you draw the crossings lines, create some draft cross section sheets with the following option changed. We are not really concerned about the draft cross section with this step. At this step we mostly after the pattern Lines.

CADD Standards

Appendix-Q

3. Use the Drawing Task Tools locate at “Design>Xsec>Linear>Utilities>Mark as Crossing” to draw a line from the start of the crossing utility to an approximate point that crosses a cross section location which generally creates a line roughly parallel to the alignment. Repeat this process for the end of the crossing element. Each crossing element should be represented with 2 new lines.

4. After all of the crossing elements have been drawn. a. “Create OpenRoads Features from plain MicroStation graphics” (see previous

instructions). b. “Set the Active Terrain” (see previous instructions). This step may have been

completed in step 2 above. c. “Drape Features on Surface” (see previous instructions).

CADD Standards

Appendix-Q

Preparing Xsec_Utility_Cells_as_Lines_(Alignment_Name) Drawing. 1. Create a 2D drawing named Xsec_Utility_Cells_as_Lines_(Alignment_Name).dgn.

Appending the alignment name to the end of the Drawing name is recommend when multiple cross section alignments are planned. This should help user associate the correct drawing with each cross section model.

2. Attach the Utility Filters. This can be done from the main menu: NDDOT > Levels > Level Filters > Utilities.

3. Reference the drawing Topog.dgn and display only utility cells by using the filter “Utility Cells”.

4. Copy these utility Cells into this Xsec_Utility_Cells_as_Lines.dgn. Use the level filter “Utility Cells” to pick the cells.

5. Detach the Topog.dgn. 6. Manually attach the cell library:

S:\STANDARD\V8i\cell\SpecialAttachment\cells_to_lines.cel. 7. Use the Replace Cells tool to replace the cells. Be sure to use “Method > Update” and

“Mode > Global”.

8. The Replacement cells will look like lines, but at this point they are still cells. Detach the “cells_to_lines.cell” library. If you don’t detach this library the correct cell will not appear in the cross sections.

9. Reference the alignment file, usually DS_Align.dgn. 10. Rotate the all the cells so that they are relatively parallel to the cross section alignment.

a. Reference in your cross section alignment model. b. Select the utility cells. c. Activate the “Rotate Point Symbol” tool from

Geopak or main menu: NDDOT > Tools > Utilities > Rotate Point Symbol. Use the OpenRoads alignment as a MS Element, Rotation > Tangent. Then click Start.

11. If the project uses multiple cross section alignments, make a backup drawing at this point. You will need to have separate versions of the “Xsec_Utility_Cells_as_Lines.dgn” in order to address the different cell rotation orientations.

12. Once the cells are rotated, use the MicroStation > Drop Element command with the Complex option to drop the cells to single line elements.

CADD Standards

Appendix-Q

13. After all of the cell have be replaced with rotate line elements; a. “Create OpenRoads Features from plain MicroStation graphics” (see previous

instructions). b. “Set the Active Terrain” (see previous instructions). c. “Drape Features on Surface” (see previous instructions).

Test and Review Utility Models The 3D utility models needs to exist or be referenced into your 3D cross section model. The utility features should display in both dynamic cross sections and sheet cross sections. If the size of the cell doesn’t appear correctly, the Drawing scale of the 3D Utility model is probably off (see previous instructions on “Drape Features on Surface”).

Cross Sections Key Index The Cross Section Key Index is locate in the Sheets.cell library. The cell “XS Legend” should be placed without annotation scale.
