Project Background I am working on a project located in northern Alberta Canada. The current application is an existing wastewater lagoon constructed in 1982. The existing lagoon was constructed utilizing compacted clay liner medium to high plasticity (clay berms and clay bottom). A recent...

Could you use vents instead... They may be more cost effective. I am working on a lagoon project as well. Did you end up using concrete/soil filled pipes as ballast in your design? Standard details for vents can be found at the below link...

The fill will be compacted to 98% SPD on all roadways. Underneath the apartments will not be compacted to 98% SPD instead the apartments will be built on piles. The 7.3 ha remaining environmental reserve area (25.1 ha total owned lot area - 17.8 ha developable area) will be undisturbed leaving...

We do have approval to develop in the floodplain. The city has seen the conceptual subdivision plan and the engineering brief and approved it. The developer has changed the lot layout a few times since the city has last seen it but the building envelope area has not changed. This subdivision...

I am looking for general feedback, links or documentation which will give me a better insight on the possible economical solutions to overcome certain problems with developing in a floodplain. I am working on the preliminary design of 25.1 ha of land which 17.8 ha will be developed. The...

Thanks guys you have been a big help

Has anyone heard of SURGE 2000. I am wondering if you know a company, person, or website where I can find a contact number to purchase a program called SURGE 2000. This program analyzes water hammer and transitional flow. I spent a couple of hours last night searching the internet for a...

The wet pond has a 7:1 sideslope where the riprap will be placed. The edge of the wet pond will be within 200m of the city's river edge. The proposed subdivision will be composed of executive townhouses and apartments. I am trying to make this pond look as natural as possible without breaking...

I have looked at my local standards which state erosion protection must be placed around the perimeter of the stormwater wet pond to an elevation of a 1:5 year water level. Is there other less expensive options or products available than rip rap. Maybe for example a type of geo-fibre or grid...

Thank you cvg for the list of books with authors. Does anyone know of any solid transportation textbooks they use as references for design. I don't need transportation modelling books. Thanks

Currently I am involved in the design of drainage, water and sewer design, grading and earthwork, and street design. This "good textbook" to aid me with these designs is what I am looking for cvg. Could you recommend some good ones. I am using the city design standards and TAC manuals. I need...

am a fresh graduate from University hired by a land development firm. I was wondering if you guys/girls could recommend me some good land development or transportation books that you use as references for design and construction. Thanks

A guardrail is warranted in one of my roadways according to the highway geometric design guide of Alberta. I was wondering how far past the critical 5m embankment drop location (the starting of the guardrail) would I extend the guardrail up the roadway in a 60 km/h zone and if the roadway has...
