Pilot reported a new parallel grass runway was constructed at X35 airport with no publication or NOTAM associated with its creation. Additionally; the airport beacon is difficult to see at night.

Narrative

New airport (X35) runway is likely to result in mid-air collisions. A short new grass runway has been cleared paralleling the eastern side of paved Runway 05-23; however; there is no NOTAM nor any announcement for this new grass runway. A few thin strip streamer flags have been secured via small poles at each end; and this grass runway cannot be seen at ground level/taxiways because of its low elevation where rain is likely to accumulate. This has created a very confusing approach to X35 when aircraft are making rapid and simultaneous radio calls for left AND right traffic for '05' or '23'. Type of traffic appears primarily para-gliders; which cross over the paved Runways 10-28 and 05-23 regardless of wind direction. Some para-gliders don't make radio calls and are hard to see and avoid.The airport (X35) beacon is not visible at night when approaching at altitude.Other pilots based at X35 have stated their requests to angle the lenses up more have gone unanswered. I remember once when low on fuel at night the relief I felt when I saw a flashing beacon 10+ miles away; at an airport I never landed at previously.
